WINT - Water Intelligence, a globally renowned company in cutting-edge water management and leak prevention solutions for construction, commercial and industrial applications, has developed a solution that detects and prevents leaks and other issues in chilled water systems and pipes. Leak prevention solution The solution prevents water damage by detecting issues, automatically shutting off water flows and isolating impacted areas. WINT has developed a solution specifically designed to detect leaks and other issues in chilled water HVAC systems. Damage from water leaks in buildings is one of the biggest sources of damage to facilities. Large buildings use chilled water systems to cool the facility and ensure that occupants are comfortable. These systems consist of lengthy piping networks filled with massive amounts of water that flow throughout the building. Water is pumped at many thousands of gallons per hour so when a pipe breaks water accumulates quickly, causing massive damage within a very short timeframe. Advanced AI and machine learning technologies WINT uses advanced artificial intelligence, machine learning and signal processing technologies WINT uses advanced artificial intelligence, machine learning and signal processing technologies to deliver extremely high detection accuracy. The solution detects drip-level leaks in chilled water pipes, allowing maintenance staff to perform corrective action before the issue becomes significant. And if pipes burst and reach damage-potential levels, the system shuts water off and isolates the impacted area. "Ongoing waste and leaks are a major source of damage and cost in most facilities," said Yochanan Mor, Head of Logistics at The Phoenix Insurance Company, adding "It's a day-to-day battle for facilities teams and insurance companies. We use WINT's suite of solutions across Phoenix's facilities to protect everything from domestic water to chilled water systems.” He adds, “Also, WINT's AI-powered technology ensures our facilities are protected against the massive damage of a water leak while cutting our ongoing water bills." Edge devices WINT's edge devices are installed on the chilled pipes in key locations throughout the facility. They use AI technology designed specifically for chiller systems combined with cloud-based computing and a user-friendly mobile app that alerts staff and enables remote control and valve shut-off. Each WINT edge device includes a high-accuracy flow meter, a processor that analyzes water flow in real time, a communication device and an optional automatic shut-off valve. Water Intelligence devices learn a building's typical water flow pattern using machine learning technology so they can detect small leaks and anomalies before they become problems. "A leak or burst chiller pipe is the stuff of nightmares for facility and operations managers," said Yaron Dycian, WINT's Chief Product and Strategy Officer, adding "Water gushes out at very fast rates and accumulates rapidly. It then flows down the building and causes massive damage in its path. Physical damages can easily reach millions of dollars, let alone the business disruption and the time to bring the facility back to order."
Hunt’s Foodservice has taken delivery of 31 new vans and trucks fitted with Carrier Transicold refrigeration equipment, in a move designed to increase the versatility of its fleet by improving cold chain integrity on multi-drop delivery routes. Carrier Transicold is a part of Carrier Global Corporation, a globally renowned provider of innovative heating, ventilating and air conditioning (HVAC), refrigeration, fire, security and building automation technologies. The new vehicles include 20 3.5-tonne MAN vans featuring Carrier Transicold Pulsor 400 MT, multi-temperature units specified by the customer. They are joined by three 7.5-tonne, two 12-tonne and six 18-tonne MAN rigids, each fitted with Supra 550, Supra 850 MT and Supra 1250 MT units respectively - a mixture of replacements and additions to the customer’s 120-strong fleet. full refrigeration capacity “Our priority is maintaining the integrity of the cold chain when the doors are constantly being opened on demanding multi-drop routes, where customers are often in close proximity to each other,” said Philip Hopkins, Group Transport Manager, Hunt’s Foodservice. “Carrier’s systems effortlessly meet that challenge, which allows us to focus on providing the highest quality service to our customers.” The Pulsor 400 MT unit uses Carrier Transicold’s patented E-Drive technology to transform the van’s engine power into electricity, providing rapid temperature pull-down and full refrigeration capacity at engine speeds as low as 1,000 rpm – ideal for congested city centers. Another benefit of the system is its ‘key out’ function, which allows the driver to leave the vehicle parked securely while making deliveries, without cutting power to the refrigeration unit. incident management service Hunt’s Foodservice’s first Carrier Transicold system was a Supra 1250 MT unit, purchased in 2015 Hunt’s Foodservice’s first Carrier Transicold system was a Supra 1250 MT unit, purchased in 2015. Having been impressed by its performance and reliability, the company has consistently selected Supra units for new trucks ordered since. Each of the units offers constant airflow, independent of truck engine speed, supplying rapid pull-down and accurate multi-temperature set point control. The company expects to operate the vans for three years, while the trucks will be in service for five years. Both the Pulsor and Supra units are backed by Carrier Transicold’s comprehensive everCOLD fixed cost, full-service maintenance package, which includes annual temperature control testing and certification, full regulatory checks and access to Carrier Transicold’s oneCALL 24/7 incident management service. frozen and chilled goods Based out of depots in Sherbourne, Fareham and Bridgwater, the vehicles will be on the road up to six days a week, making deliveries of quality frozen and chilled goods, including fresh meats and ice cream, to customers across southern England.
Control Systems have always played an important part in the function of HVAC systems and for many years were centered around the safe and optimum performance of the hardware deployed. Every HVAC system is a closed-loop process, with inputs fed into control logic that determines the best course of action to achieve the desired output. Energy management and integration into Building Information Management saw the advent of energy-saving techniques like free cooling and night-time purge reduce mechanical cooling loads, whilst occupation data allowed greater holistic management of systems. These are well-recognized practices that are being refined using predictive weather data, additional focus on heat recovery and more environmentally energy sources. Control Systems have always played an important part in the function of HVAC systemsThe scope of the typical systems loosely described above are around the management of systems on one site and their operation and maintenance tends to be centered around that particular location. Multi-site Development & Management The UK temperature-controlled warehousing market tends to develop on a project-by-project basis that fosters the site-by-site focus of ongoing management and maintenance. For multi-site logistics operators and manufacturers and distributors with a multi-site portfolio. this approach has the following disadvantages: Disparate system KPI data collection and reporting Setpoint adjustment left to untrained operators who apply their individual assessment of compliance risk and often don’t consider the financial and operational implications of fine-tuning (or meddling) Enterprise-wide energy management is difficult to control Duplication of staff tasked with reporting and maintenance Inconsistency of measurement and interpretation Slow response to system failures Poor interpretation of operational processes that impact system efficiency Portfolio Management The distinction here is that a portfolio of temperature-controlled sites is managed centrally instead of independently. The enabler to the solution is the rapid Energy management and integration into Building Information Management saw the advent of energy-saving techniquesdevelopment of access control systems and data communication. The next step is vital in the customer engagement process; what do they want to see? What’s important and what is not? How often do they want to see it and in what format? From experience of going through this process this is a voyage of discovery for the warehouse operator in understanding the stakeholders in their business. Quality and compliance managers are the obvious starting point, facilities managers, finance managers who are tasked with reducing energy costs, customer service and the end customer. Alongside the KPI monitoring, Jet Environmentals created a hierarchy of alarms management that alerts the right people with system information, that triggers a sequence of actions driven by the data. Trends are monitored to predict where there might be a problem on the horizon so action can be taken before there is an issue. Faults and failures are alerted instantly and corrective action alerts sent to the right people. Conclusion The continuous development of HVAC controls and reliability of secure data connections has provided a means of improving performance, lowering cost and building trust in provider/user relationships. To be successful, the roll-out of such a project requires the willingness and collaboration of all parties and the groundwork defining stakeholder requirements is vital in defining a scope that meets expectations.
Sensors have been used in buildings since the invention of air conditioning to understand how buildings are performing, from in-room temperature sensors, to sensors on plant equipment, motors, ductwork and pipes. The Internet of Things (IoT) has enabled more sensors of different types to be deployed in more locations throughout the building easier than ever before. The point of installing and using IoT sensors is to gain deeper insight into how buildings are performing, and ensure buildings are healthier, more productive for people to work in, more effective to run and more energy efficient. This article looks at in-room sensors, such as temperature, air quality and occupancy, and how IoT sensors can help improve building performance. The benefits of IoT sensors is that they are easy to install, both physically and from a commissioning perspectiveThe benefits of IoT sensors is that they are easy to install, both physically and from a commissioning perspective. Cabling is usually minimal or not required at all: IoT sensors are battery powered, or require simple USB power (from a plug socket) or utilise Power over Ethernet (PoE). IoT sensors use low power wireless protocols (such as Bluetooth, Mesh etc) to send data, and thus can be placed anywhere within a building and do not require multiple physical IOs for integration. Unprecedented amounts of data IoT sensors are usually cost-effective such that thousands of sensors can be deployed throughout the building without much effort. This gives an unprecedented amount of data to building managers, which comes with its own challenges – How to make use of this data? There are two ways to utilise this data to improve building health, performance and efficiency: Use an effective monitoring platform or data analysis tools to turn raw data into actionable insights. This can provide the building and facilities team with insights to be more pro-active, and spot temperature, air quality, overcrowding, etc issues even before the users or tenants begin to notice e.g. it’s too cold, too drafty, too stuffy, etc. Integrate the live data from the IoT sensors straight into the Building Management System (BMS) and create new control strategies to automate the building further. This requires a bit more integration and commissioning work upfront, but the performance and efficiency benefits through automation will give a fast Return on Investment. The key here isn’t the sensor integration itself, but the building control strategy that will be the logic to which the building automation fucntions. Some use cases of IoT sensors are: Temperature and HVAC A common problem I’ve heard from many buildings is that existing temperature sensors that connect to the BMS have been placed in the ceiling, and not at head height. Using battery powered IoT temperature (and humidity) sensors, and sticking them to the wall at head height, is a quick and easy way to measure temperature where it actually matters.Data can be used to plot temperature heatmaps, find hot or cold spots, or analyse the solar heat gain Data can be used to plot temperature heatmaps, find hot or cold spots (e.g. if two nearby FCUs are working against each other, one heating one cooling); or analyse the solar heat gain, and adjust internal loads. The IoT temperature sensors can be connect to the BMS to provide more accurate temperature data to FCUs instead of the sensors in the ceiling. In general, IoT senors can easily be reconfigured and moved, e.g. during a fit out. But care needs to be taken to keep a close eye on the sensors and which room/space they relate to. Battery will need to be changed every 5 years. The IoT temperature sensors are cheap enough that they can simply be replaced with new ones e.g. the sensors element need recalibrating. Indoor air quality sensors and HVAC Accurate CO2 level sensors (which use duel channel NDIR technology) with IoT connectivity are getting cheaper and can also be used to do ‘heatmapping’, of the building, and provide accurate insights on indoor air quality. Similarly, heatmaps can be done with particulate matter sensors (PM10, PM2.5, PM1), VOC sensors and others embedded in an IoT connected sensor. CO2 level sensors in Accurate CO2 level sensors with IoT connectivity are getting cheaper and can also be used to do ‘heatmapping’particular are important as the level of CO2 indoors affects our cognitive ability. High indoor CO2 levels hinder our productivity. Indoor CO2 levels of 900ppm to 1400ppm and higher, which are seen in buildings with poor ventilation, reduce our ability to make decisions and use complex information by 15% to 50% and higher, respectively. Indoor CO2 levels are also a good indication of the risk of infection, as people breathing are usually the main source of CO2 in buildings. So being able to monitor CO2 levels in every space inside the building will provide building owners, tenants and users with reassurance with regard to COVID-19 related challenges. ‘eCO2’, a derivative from VOC sensors, should NEVER be used as a measure of CO2 levels. All CO2 sensors elements need to be recalibrated every 3-5 years. Occupancy level and HVAC Knowing the occupancy on every floor of the building can be used to control HVAC systems. Through BMS integration, controlling the flow of ventilation dynamically, based on real-time floor-by-floor occupancy, allows the building to ‘breathe’ with actual demand.Employing an occupancy-based, dynamic control strategy on the BMS reduces the energy consumption for buildings that rarely see full occupancy This balances the building from a technical perspective, and improves air delivery by opening up more ventilation capacity. Employing an occupancy-based, dynamic control strategy on the BMS, not only improves the indoor air quality, but also reduces the energy consumption for buildings that rarely see full occupancy, or have dynamic use (which will only be more common as we begin to work-from-home more often) Measuring the number of people is difficult, which usually means expensive. One way to count people is using PIR sensors places under each desk. This can get expensive for 1,000 desks even if one IoT PIR sensor is relatively cheap. Another way is to use a less accurate, but cheaper method, e.g. using long-range sensors that count the number wireless devices in a vicinity / floor, and using that as a proxy for percentage occupancy levels. Summary 1,000s of IoT sensors can be easily installed anywhere throughout any building. To get the best out of an IoT system a clear use case (or set of use cases) is necessary. By understanding the use cases and benefits, the right design, UI or integration can be used to maximise the cost-benefit ratio for the specific use cases, for example: BMS integration for IoT temperatures sensors; Relevant platform UI and analysis to extract actionable insights for the Facilities Management team from the raw IoT sensor data; or Correct HVAC control and automation strategy based on occupancy level data.
In the summer of 2018, a customer was facing a real problem – their resident satisfaction at two properties needed some work, and they were just about to hit the hot summer busy season – which can be notoriously difficult if residents experience air conditioning issues. Fortunately, they were able to implement a preventative maintenance and HVAC asset management solution at one of their properties. At this property the customer wound up doing only 3% unplanned replacements out of 300+ units – and had a customer satisfaction score of 97%. Unfortunately, they did not have time to implement this solution at another one of their recently acquired properties and wound up with 17% unplanned replacements on 700+ units and a 77% resident satisfaction score. Finding Relevant HVAC Solutions The search for a HVAC technology solution that is focused on energy efficiency and provides multifamily and commercial property owners with ease and insight into their HVAC property management needs, can be daunting.Property owners have several boxes to check: proactive maintenance, environmentally friendly solutions, always with an eye to the bottom line. HVAC is one of the largest consumers of energy in commercial and multi-family properties, accounting for up to 40% of a building’s energy consumption. It may be hard to believe, but in totality, businesses are wasting over 60% of the energy they purchase every year. And the inefficiencies can build upon one another. HVAC systems are typically the largest consumers of energy in commercial and multi-family properties, accounting for up to 40% of a building’s energy consumption. There is also the matter of the state the HVAC system in play. Poorly installed or malfunctioning units can increase energy consumption by another 30%. Add to that another 18% energy increase from poorly optimized heating and cooling processes and it is possible to see up to 90% of energy costs directly related to HVAC. Considering Energy Costs HVAC is one of the largest consumers of energy in commercial and multi-family properties, accounting for up to 40% of a building’s energy consumption. Not only is high energy use costly for business operations, but it has an impact on the environment through the carbon that HVAC systems emit. That is why technological innovation and a reputable contractor network for commercial and multi-family building HVAC investments is a crucial consideration for commercial building owners. Commercial and multi-family properties that ‘back burner’ system innovation at this critical time will find it increasingly difficult to compete and maintain their resident satisfaction ratings by staying ahead of the inevitable replacement and repairs. Building owners must make time to consider what the future of big data and smart platforms looks like. In our world of data, implementing HVAC services like this are no longer a luxury; they are a necessity. In fact, commercial buildings can attain a savings of roughly 18% on whole-building energy consumption from installing smart technologies to optimize services. Adopting Smart Technology Partnering with the right service provider will have a dramatic effect on the ultimate success or failure of an HVAC rollout in several areas such as acquiring quality, cost-effective equipment, ensuring compliant and thorough installation, accessing knowledgeable and rapid repair personnel who can also maintain equipment on an ongoing basis. Whether your company is looking to adopt HVAC smart technology for the first time or replacing an out-of-date solution, here are a few factors to consider that will help in making your choice when embarking on a HVAC contractor network. Commercial buildings can attain a savings of roughly 18% on whole-building energy consumption from installing smart technologies Look for an experienced professional It may be tempting to seek an HVAC professional based on the lowest bid received, but there are other considerations that must be taken into account. Look for a solution provider with industry experience and a history of demonstrated success in managing technology from roll-out to deployment. When you meet with potential partners, insist on viewing live solutions. A network of contractors Look for an HVAC professional that is connected in their local community. Other considerations include the size of their contract network and are those contractors well-vetted? Ensure that the network has a reputation for meeting deadlines and affirms that it can meet yours. Ask if there is one point of contact for the life of the job, too. It’s an important detail to know who your point person is and with whom you will be contacting for the questions that will arise along the way. Have an eye to the future Ensure that the HVAC technology under consideration possesses the capability to handle large volumes of data and a large number of users at the same time. Ask some questions about the peak season and confirm the contractor has planned ahead and thought through a scenario of how to prioritize repairs during a heat wave, for example. What about considering predictive analytics? What benchmark performance measures do they have in place? Do they use state-of-the-art remote monitoring, giving them a 360-degree view of your entire property portfolio? No hassle, no waiting Although larger than the residential market, commercial demand gains will increase at a slower rate due to an expected slowdown in commercial construction activity. As 2021 is quickly approaching, the market changes can present both dynamic opportunities and challenges for technology platforms. What’s key here is availability of product and services. Ensure that the contractor has the resources to accomplish your objectives. Are they vendor neutral? Consider and compare the price of labor and equipment. Also, confirm that there are multiple channels of ordering paths for optimization. How to choose your solution The installation and implementation of all of a building’s HVAC assets should consider how the condition analysis of each unit captured. Make certain there is a clear representation of how data is being collected from your contractors and that you understand your role in consuming and interpreting that data. Ask about the kind of alerts and sensors that will be used and how the data collected is then presented to you. The technology provider should be able to provide guidance into which building metrics should be measured and offer technology solution that gives property owners visibility into their entire asset portfolio, empower managers, and make precise decisions about HVAC condition and energy-efficiency. Building owners must make time to consider what the future of big data and smart platforms looks like The reason why most residents do not renew their leases is because of poor staff performance and assistance. Technology solutions are now considered mission-critical for property managers, owners, and investors who want to excel at HVAC service needs. If the HVAC is in disrepair for too long a period, tenants will move onto another property. According to data from the U.S. Environmental Protection Agency’s ENERGY STAR program, companies spend more than $20 billion on energy, annually. By replacing air conditioning equipment that has been in operation for 10 years, facilities can save 20-50% on energy and maintenance costs. Taking some steps toward technology via a contractor network can help ensure excellent staff performance and assistance, resulting in higher residential satisfactory ratings, tenant retention, as well as energy and cost savings.

As schools work to reopen safely in the midst of a global pandemic, HVAC is at the center of the mission. Adequate ventilation and effective air filtration are critical elements to ensure safe indoor air quality for educational institutions. Many schools are housed in older buildings that may not have been adequately maintained. Transforming them to address the new challenges of minimizing exposure to the novel coronavirus is that much more difficult. In fact, a recent study by the U.S. Government Accountability Office found that more than half of the nation’s school districts have outdated building systems. Some 40% of the nation’s 13,000 school districts need new or updated HVAC systems in at least half of their schools - that’s almost 40,000 schools that have issues of poor indoor air quality. Funding is an ongoing problem, especially as the pandemic has undermined the financial health of many school systems. interior building components Even so, classroom air quality is now more important than ever before. Introducing more fresh air into a building - with better ventilation - is an important consideration to minimize spread of the novel coronavirus. Already, many schools are chronically under-ventilated. Extending HVAC system operating hours can provide more ventilation before and after the building is occupied. Building code standards typically require schools to circulate the air inside classrooms at least three times per hour. With the threat of COVID-19, the recommendation is to target five clean air changes per hour. However, increasing outdoor air ventilation comes with a toll of more indoor humidity and less comfortable temperatures. Additional dehumidification is needed to avoid condensation on interior building components such as piping and ductwork. And the solutions are not one-size-fits-all. supplemental air cleaning Related to filtration, ASHRAE suggests use of MERV 13 filters, which can capture particles as small as 03-1.0 microns There are many variables in terms of the educational facilities and HVAC systems such as complexity, flexibility, age and condition. Mechanical needs of each school depend on available resources, school demographics and building characteristics. As classroom occupancy becomes less dense through social distancing, the changing impact on HVAC needs should be factored in, too. In addition to ventilation, there are considerations of filtration and supplemental air cleaning. Related to filtration, ASHRAE suggests use of MERV 13 filters, which can capture particles as small as 03-1.0 microns. However, higher efficiency filters can restrict airflow and cause strain on HVAC systems, especially older models. An alternative is using portable air filters with HEPA filtration for each classroom. Another consideration is possible use of UV-C for in-duct air disinfection, although the systems must be compatible to existing HVAC systems. airborne infectious diseases There are also upper-room germicidal UV-C fixtures for infection control, which work by interrupting the transmission of airborne infectious diseases in high traffic communal areas. Use of bipolar ionization is another way of deactivating airborne viruses using proactive air purification. HVAC-mounted devices use positive and negative ions to destroy viruses for cleaner, healthier air and less risk of infections. However, there is limited information about the effectiveness of ionization systems, especially related to the novel coronavirus. In addition, schools should examine air handling systems to ensure dampers are connected, fan belts are operative, and that cooling and heating coils are working. Cleanliness of units, condensate drain pans and related components is also paramount.
Building Information Management (BIM) software creates an intelligent 3D model of a design or building project and provides documentation, coordination and simulation through each step of the project’s lifecycle, from planning to design, building to operation and even maintenance. Use of a 3D model enables stakeholders across various disciplines to visualize and understand every detail of a project before it is built, makes it easier to document a project, and facilitates communication among various parties. Construction logistics and details are shared among contractors, including HVAC, and teams can work more efficiently. Any updates to a project can be made easily and communicated universally; there are fewer mistakes because of miscommunication. Reworks are minimized. BIM modeling software, for example, can help designers lay out ductwork and pipes in a new structure, and automatically detect any collisions or clashes among objects before they become a problem in the “real world.” Facilitating communication of specifications Contractors can create an accurate virtual model of proposed new systems and/or of existing systems. BIM modeling also provides a central repository for all construction design documents, characteristics and operational details. BIM software therefore becomes a resource where designers and planners can access information and solve any future problems during the planning stage. Facilitating communication of specifications saves money during construction. If there is a change to a diffuser or other component on a floorplan, that change is automatically updated wherever the diffuser is located, thus making engineering design changes easier and more efficient. Any equipment or component can be easily swapped out to improve performance, and all drawings are updated automatically with the changes. Higher productivity equates to less project time and costs. enhance construction productivity Learning how to leverage BIM can provide a key differentiator from more traditional HVAC competitors Having a single, accurate point of reference enhances construction productivity and cuts down on cross-referencing and approval times. Understanding BIM and being familiar with operating in a BIM environment provides an advantage for HVAC companies seeking to be considered for projects. Learning how to leverage BIM can provide a key differentiator from more traditional HVAC competitors. And it makes the job easier: BIM facilitates coordination in the field among HVAC installers, energy contractors, and building owners. In the building industry, BIM enables extra HVAC planning during preconstruction and construction phases. Ductwork can be routed for the most efficient air flow and while avoiding clashes with structural elements or other equipment. An engineer can download data from BIM drafting files and carry out load and performance calculations using software to ensure a better design. building heating system Increasing use of BIM for HVAC projects enables engineers to design systems that are energy-efficient, which is an important factor given that the HVAC system will account for 30 to 40% of a building’s energy costs. New advantages of BIM for HVAC are emerging, too. For example, Austrian technology researchers have examined the use of BIM data to automatically generate control strategies for energy systems, thus simplifying and accelerating the commissioning phase. The methodology creates control strategies of a building heating system with several variations of renewable energy systems and includes both heat provisioning and a distribution system.
The Wyss Institute at Harvard University has developed an evaporative cooling system that uses a specially coated ceramic to cool air without adding humidity. Researchers say the approach can yield more affordable and environmentally friendly air conditioning systems for the future. ‘cold-SNAP’ system The ‘cold-SNAP’ system uses a water-repellent nano-scale surface coating that is applied selectively to surfaces of a 3D-printed ceramic heat exchange. The result is much cooler buildings with less humidity. ‘cold-SNAP’ is short for cold superhydrophobic nano-architecture process. The invention uses evaporative cooling, which happens when hot air is put in contact with water. As the water evaporates, it cools the air but adds moisture. Use of the water-repellent coating separates the moisture from the cool air to provide an inexpensive source of cooler, dryer air that can cool a building in lieu of traditional air conditioners. Evaporative Cooling technology The hydrophobic coating is selectively applied to components that will manage the flow of dry air The approach is a union of old and new – combining ceramic, one of the oldest, cheapest and most widely available building materials, with the novel hydrophobic surface coating developed by Wyss Institute. Because ceramic is malleable, the heating exchange unit can be produced via extrusion or 3D printing of a single piece, with its shape adjusted to maximize surface area available for heat transfer and evaporation. The hydrophobic coating is selectively applied to components that will manage the flow of dry air. Variation on indirect evaporative cooling (IEC) systems The specialized coating separates incoming hot air from outgoing wet air, allowing the hot air to be cooled by circulating water without adding humidity to the inside of a building. ‘cold-SNAP’ is a variation on indirect evaporative cooling (IEC) systems, which use complex heat exchange units that make them difficult and expensive to manufacture. Researchers say the approach can create low-cost, efficient air-cooling units to meet the world’s increasing demand while using 75% less energy. The system can be up to four times more efficient than conventional air conditioners as measured by the coefficient of performance (COP), the ratio of cooling to required energy. ‘cold-SNAP’ was designed by a multi-disciplinary team of scientists and designers from the Wyss Institute’s Adaptive Material Technologies Platform, Harvard’s Graduate School of Design (GSD), and the Harvard Center for Green Buildings and Cities (HCGBC). Integration into evaporative cooling systems The new technology could be integrated into existing evaporative cooling systems and sold as environmentally friendly air conditioners in a variety of climate zones. It could even be manufactured into the facades of buildings, thus cooling the space within, using only the energy needed to pump water to the system. With global warming causing a rise in the Earth’s average temperature, worldwide demand for air conditioning systems that do not contribute to that climate change increasingly will be in demand. A growing middle class throughout the world is also contributing to demand. No humidity added to the air ‘cold-SNAP’ does not add humidity to the air and works well in humid, tropical climates, as well as dry, hot climates Because ‘cold-SNAP’ does not add humidity to the air, it works well in humid, tropical climates (where it is sorely needed) as well as in dry, hot climates like the Middle East. Traditional electric air conditioners use mechanical vapor compression to convert a chemical refrigerant back and forth between its liquid and vapor forms, absorbing heat during vaporization and then removing moisture during condensation. Traditional systems use a large amount of energy to cycle the refrigerant, which increases costs, not to mention the refrigerants contribute to global warming. Historically, the environmental impact of such systems was a hidden cost that was not considered. Wyss Institute Validation Project In 2019, ‘cold-SNAP’ was named a Wyss Institute Validation Project, which puts it on track to become commercialized. The validation program seeks to ‘de-risk' technologies and demonstrate that they can be scaled up for commercialization. The Wyss Institute for Biologically Inspired Engineering at Harvard University emulates Nature’s design principles to engineer new, ‘bio-inspired’ materials and devices with high-impact applications in healthcare, manufacturing, robotics, energy, and sustainable architecture. The cross-disciplinary faculty, technical staff, students, and fellows undertake high-risk research and technology development.
Nicknamed the gateway to Southern California, the city of Ontario, as well as neighboring city Montclair, is home to the third largest elementary school district in California, the Ontario-Montclair School District (OMSD). Founded in 1884, the district also incorporates portions of the city of Upland, and unincorporated areas of San Bernardino County, comprising 24,000 students in 26 elementary schools and six middle schools. Ontario-Montclair School District Ontario-Montclair School District’s overall mission is simple yet speaks volumes to its dedication to all students, to do whatever it takes to guarantee its commitment in providing the highest quality education for all students. To meet this mission head-on, OMSD contracted with TMAD Taylor Gaines, a professional engineering consulting and services firm. Ontario Montclair School District was interested in reducing their overall energy costs by 20%" “Ontario Montclair School District was interested in reducing their overall energy costs by 20%, they along with other school districts throughout California were mandated to reduce their overall energy costs,” said John Simmons, RCDD, LEED AP, and Project Manager for TMAD Taylor Gaines. He adds, “We initially ran some numbers based upon information we found on Bard HVAC’s website, and through consultation with Geary Pacific Supply, Bard’s largest West Coast distributor.” Geary Pacific, distributor of new HVAC units Based upon the scope of the projects in consideration, the money available to fund them and the overall cost of the units in consideration, as well as overall potential energy savings, TMAD Taylor Gaines recommended that OMSD select Geary Pacific as the distributor of the new HVAC units. “We considered other companies as part of our overall recommendation but in all honesty we were impressed by a couple of things. First, Bard Manufacturing had a wealth of product and technical information about their products on their website, including case studies of other customer successes. That in combination with Geary Pacific’s previous experience working successfully with the School District made our recommendation a simple one,” added John Simmons. Bard wall-mounted HVAC units deployed “Our District was already familiar with Bard because we had success using some of their other wall mounted units on several of our modular school buildings,” said Craig Misso, Director of Facility Planning & Operation at Ontario Montclair School District, adding “Our goal was to not only upgrade our facilities and make them more energy efficient, but also work to reduce some of the HVAC noise inside the classroom, as well as save on the purchase, operation and maintenance of all of the units at our schools.” TMAD Taylor Gaines and Geary Pacific’s approach was to do the retrofit in several phases. The pilot project encompassed one site, Sultana Elementary School, which included 24 re-locatable buildings, made up of both newer and some older construction. Bard WG*S Step Capacity Series units with CO2 sensors TMAD Taylor Gaines and Geary Pacific started doing groups of schools, encompassing 14 different building sites “Sultana was a great school for the pilot because there were a lot of little issues to contend with and work through,” stated Simmons, adding “The Bard WG*S Step Capacity Series units with Energy Recovery Ventilators and CO2 sensors worked great and we were initially very surprised at how quiet they actually operated.” After that, TMAD Taylor Gaines and Geary Pacific started doing groups of schools, encompassing 14 different building sites. Group one included 6 schools and approximately 83 units while Group 2 included 8 schools and 101 units. It was during the second group of installations that TMAD Taylor Gaines realized that putting in units that required the installation of underground gas piping was not the best solution for all classrooms. Bard’s Quiet Climate 2 units That’s when Geary Pacific recommended utilizing Bard’s Quiet Climate 2 units with Energy Recovery Ventilators and CO2 sensors in about 1/3 of the overall installation. “Bard’s Quiet Climate 2 units are some of the most energy-efficient HVAC units on the market today,” said Maury Tiernan of Geary Pacific, adding “Plus the operational sound level is extremely low and is greatly appreciated by the students and teachers.” John Simmons said, “We were really pleased at how easily these units were able to be retrofitted into the re-locatable classrooms. There are almost no changes and smooth sailing in almost all cases.” Quiet, efficient operation The dramatic reduction in operating noise levels was an added improvement and benefit for which Craig Misso was particularly proud. “At Sultana, we invited some of the teachers and our principal over to see the new classrooms. Our principal asked, ‘Why aren’t the new HVAC units running’? I had to laugh, because I knew they were on. They were just so quiet nobody could tell that they were working. That moment sold every teacher on the Bard units,” added Craig Misso of Ontario Montclair School District. “From the very beginning, Geary Pacific became our partner in the success of the project,” stated Simmons, adding “Always available to answer questions on-site and knowledgeable about all aspects of the product and installation I can honestly say they can’t do anything wrong by me. Geary Pacific and the engineers at Bard Manufacturing came through in every way possible and more.” Wall-mounted heating and cooling equipment expert Bard’s HVAC products offer a combination of quiet operation, and energy efficiency Over thirty years ago, Bard Manufacturing began solving the comfort needs of schools across the country by providing wall-mounted heating and cooling equipment. Bard’s HVAC products offer a combination of quiet operation, and energy efficiency, with unsurpassed quality and dependability that make them the #1 choice for schools. With three, state-of-the-art manufacturing facilities and a global distribution network, Bard’s commitment to quality and product innovation begins with its commitment to research and development. With features like self-diagnostics and self-programming energy monitors, Bard delivers products that provide tangible solutions for any school. Energy and cost savings “The Bard units reduced ambient classroom noise levels by over 75% and further gave us a 50% savings in energy,” said Misso, adding “This savings allowed us to also install software on our computers that automatically turns off the lights and the AC, when the classrooms are unoccupied, which further increased our savings. Our hope is to have the funds necessary to install all 280 Bard units as specified by TMAD Taylor Gaines.” Misso concluded, “Geary Pacific has been extremely professional and service oriented throughout the project. Because of our School Board’s commitment to energy conservation, our District will receive a dual reward, recognized energy savings and efficiency with an enhanced classroom environment for our students and teachers. We couldn’t ask for anything more.”
Living in the McLean County Unit District No. 5 region ensures one thing that children will receive one of the finest educations available. With one of its high schools ranked in the Top 50 Public High Schools in Illinois and listed in U.S. News & World Report’s Nation’s Top Schools, Unit District No. 5 is the place where excellence in education takes on a new meaning. Replacing antiquated HVAC systems But excellence doesn’t come without a price. In the current economic environment, maintaining and improving upon existing school facilities remains one of the most significant challenges for administrators and educators alike. That’s why officials turned to a solution that proved both unique and highly practical, when six schools in the district faced antiquated HVAC systems, nearing the end of their life-cycle. Upgrading and retrofitting school HVAC systems CM Engineering and Earth City Distributing understand the challenge of maximizing facility investment dollars CM Engineering and Earth City Distributing understand the challenge of maximizing facility investment dollars when it comes to upgrading and retrofitting school facilities. They also realize the key role those facilities play in keeping a school educationally competitive. The first schools from the Unit 5 School District to undergo retrofits included Oakdale Elementary School and Glenn Elementary School. Each school had ceiling limitations which made a conventional rooftop boiler-chiller system impractical. “We wanted a system that would be easy to service and maintain, provide cooling and be energy efficient,” said Jeff Monahan, Director of Maintenance for McLean County Unit District No. 5. Bard QTEC ground source heat pump installed “We had experienced earlier success working with a school in McComb, Illinois, where using a new type of piping system and the Bard QTEC ground source heat pump saved us over 50% in installation costs,” said Kirk Mescher, President of CM Engineering. Kirk adds, “Using Bard Manufacturing’s QTEC product in the Unit 5 School District applications was not only practical, it was the win-win solution in terms of reliability and efficiency in operation.” Between 2006 and 2008, 112 Bard QTEC units were installed in 6 schools. “Between CM Engineering’s unique design approach and Bard’s very efficient QTEC unit, the installation at all of the Unit District No. 5 schools couldn’t have gone any better, “ said Mike McManus, Owner of Earth City Distributing, a local Bard distributor, adding “Not only are the units energy-efficient and incredibly quiet when operating, they can be easily accessed for service.” Bard’s wall-mounted heating and cooling equipment Over thirty years ago, Bard Manufacturing Company began solving the comfort needs of schools across the country by providing wall-mounted heating and cooling equipment. Bard’s products offer a combination of quiet operation, and energy efficiency, with unsurpassed quality and dependability that make them the #1 choice for schools. With three, state-of-the-art manufacturing facilities and a global distribution network, Bard’s commitment to quality and product innovation begins with its commitment to wide-scale research and development (R&D). With features such as self-diagnostics and self-programming energy monitors, Bard Manufacturing Co. delivers state-of-the-art products that provide tangible solutions for any school’s needs. Enhanced serviceability The QTEC’s serviceability is also a contributing factor to Unit District No. 5’s overall success “What we got by using Bard Manufacturing’s QTEC product was an HVAC system that not only provided heating and cooling, but did so while also providing more than a 40% savings in total utility costs, without upgrading windows or insulation,” said Jeff Monahan. The QTEC’s serviceability is also a contributing factor to Unit District No. 5’s overall success. “I love the fact that the units are virtually maintenance-free,” stated Monahan, adding “They’ve basically reduced our service calls to near zero.” Energy estimate from CM Engineering “Whenever any of our school clients are open to the idea of having an in-room unit installed, we always spec the Bard QTEC units. In fact, in all the years, since we’ve been in business, we’ve never installed anything else inside a classroom,” said Kirk Mescher, President of CM Engineering. With Unit District No. 5, CM Engineering initially gave them an energy estimate that proposed they could provide the schools with heating and cooling at no additional operating cost. Energy and cost savings Mescher adds, “Not only were we able to achieve that goal, but because of the Bard QTEC units, we were able to surpass it, helping the schools reduce their overall utility costs significantly, in some cases by over 40%.” He further stated, “For any school, anywhere in the country trying to save money on installation, service and energy costs, not to mention lowering overall ambient noise in a classroom, these are significant enough results that simply can’t be ignored.” Quiet and comfortable QTEC units Bard’s QTEC unit is designed to be installed inside the classroom, fully engineered to be quiet and comfortable Success with the retrofit of their six schools has, in fact, led McLean County Unit District No. 5 to approve installation of additional Bard QTEC units in a seventh school during the summer of 2009. Bard’s QTEC unit is designed to be installed inside the classroom, fully engineered to be quiet, comfortable and aesthetically pleasing. QTEC units are designed and tested to operate at 20% above federal standards with easy installation features that make servicing fast and simple. Bard’s QTEC units can provide the following features: A one-piece factory unit with individual room climate control Designed for fast installation and easy servicing Sound deadening insulation Simple utility hookups Integrated energy recovery ventilator Controlled dehumidification A rating for efficiency that is 20% above Federal Standards
One won’t find bustling cities or lots of traffic in Montgomery County and that is just the way residents like it. Montgomery County is located in south-central North Carolina, an hour drive from Charlotte and just under two hours from Raleigh and Fayetteville. Eighty percent of the county comprises the geologically pristine Uwharrie National Forest, which provides a beautiful, scenic backdrop for quiet, country living. With children under 18 accounting for just over 25% of the local population, Montgomery County Schools' mission is to ensure that all students are prepared for the opportunities by addressing the challenges. Cost-Effective solution One of these challenges was directly related to a new elementary school – Green Ridge Elementary School - the district was planning to build in the town of Biscoe. “We recently completed building another school in the district that used a combination boiler/chiller to heat and cool the school”, said Bill Mingin, Maintenance Director for Montgomery County Schools. All Seasons recommended utilizing the wall-mounted design of Bard’s Quiet Climate 2 unit “Unfortunately, we found the high cost of fuel oil combined with the high cost of installing this type of system, forced us to come up with a better, more cost-effective solution for Green Ridge.” That’s when Montgomery County Schools turned to Drayton Stott of All Seasons Commercial HVAC Distributors, the local Bard dealer. Overall construction costs “I was very familiar with Bard because we had great success using some of their wall mounted units on several of our retrofitted schools,” said Mingin. “We were hoping, however, to reduce some of the overall operational noise and costs within the new building even more.” That’s when All Seasons recommended utilizing the wall-mounted design of Bard’s Quiet Climate 2 unit – albeit on the outside of the building. “The Bard Quiet Climate 2 units are some of the quietest HVAC units on the market today,” said Stott. “Green Ridge Elementary School also benefitted from a reduction in overall construction costs, including cement work, steel framing, the cost of running ductwork and construction of a maintenance and mechanical boiler/chiller shed.” Utilizing the Quiet Climate 2, Stott was also able to also provide each room and teacher with individual control over their room’s temperature. Enhanced operational efficiency “This enhanced operational efficiency in several ways, including better and more even temperature control throughout each classroom,” said Mingin. “Plus, if any particular unit needed maintenance, it wouldn’t mean that the whole system had to be shut down. By having the units installed on the outside of the building we could work on the units without disturbing the teachers or the students inside.” The school had the added benefit of turning units off or on as needed" “The school had the added benefit of turning units off or on as needed depending on whether or not individual rooms were in use.” Another big improvement was the overall cost and installation of the Bard system. “Our mission is to provide our students with the educational building blocks that will prepare them to ultimately compete in a global economy,” said Donna Kennedy, Principal of Green Ridge Elementary School. Wall-Mounted heating “Working with Bard, we were able to save Green Ridge Elementary over $800,000 in installation and purchasing costs over a conventional system. That savings gave us the opportunity to purchase a complete technology package for our school, including smart boards and computer labs in every classroom. As a former AC service technician, I have to say that I’m extremely impressed with the Bard Quiet Climate units– they actually make no noise at all,” said Matt Wolf, a teacher at Green Ridge Elementary School. “They make teaching and learning a quiet, comfortable experience.” Over thirty years ago, Bard began solving the comfort needs of schools across the country by providing wall-mounted heating and cooling equipment. Bard’s products offer a combination of quiet operation, and energy efficiency, with unsurpassed quality and dependability that make them the #1 choice for schools. Self-Programming energy monitors Bard delivers products that provide tangible solutions for any school With three state-of-the-art manufacturing facilities and a global distribution network, Bard’s commitment to quality and product innovation begins with its commitment to research and development. With features like self-diagnostics and self-programming energy monitors, Bard delivers products that provide tangible solutions for any school. “With the Quiet Climate 2 units our teachers and students never have to worry about room temperature interfering with classroom learning,” said Kennedy. “Whenever we have a weekend community activity, teachers tutoring in off hours, or classes going on night, we know we can make those spaces comfortable without wasting energy in unused classrooms.” “Our experience with Bard products over the years in retrofitted schools has been excellent and the Green Ridge Elementary School results confirm that Bard performs as well in new schools as they do in older, existing school buildings,” said Mingin. “Bard’s ability to give us individual room dehumidification is another benefit that’s hard to quantify – we just don’t have any of the problems associated with high humidity.”
As Albert Einstein once said, “We can't solve problems by using the same kind of thinking we used when we created them.” That wisdom has been put into practice in the form of a smarter approach in the way modular schools can be built and used. Pre-fabricated, modular classroom In 2006, the Montgomery County Public Schools in Maryland, in partnership with the Council for Educational Facility Planners (CEFPI), held a national design competition, The Portable Classroom Design Challenge, to create a pre-fabricated, modular classroom unit that was environmentally sustainable, or green. This competition led to eventual development and installation of one of the most uniquely created modular spaces ever conceived, indeed the award winner of the design competition. Triumph Modular of Littleton, Massachusetts, in partnership with ARC/Architectural Resources Cambridge and builder NRB Inc., won the design challenge because of their revolutionary, new modular classroom. Relocatable Green Modular Classroom Relocatable Green Modular Classroom comes designed with many LEED-focused design elements Aptly named the Relocatable Green Modular Classroom, it's also the first modular classroom to be designed with many LEED-focused design elements. “Our goal was to create a high-quality, portable classroom that was green, one with environmentally conscious materials used in its design and operation. The design was smart in the way that it used resources and provided heat, light, unsurpassed acoustics and air quality within the space,” said Cliff Cort, Founder of Triumph Modular. In fact, it’s estimated that the Relocatable Green Modular Classroom performs 56% better, in terms of overall energy costs, than similar, older style modular units that often use almost three times as much of energy as a permanent school building. Wall-mounted heating and cooling equipment Thirty years ago, Bard Manufacturing Co. Ltd began solving the comfort needs of schools across the country by providing wall-mounted heating and cooling equipment. Bard’s products offer a combination of quiet operation, patented ventilation packages, unsurpassed quality and dependability that make them the #1 choice of many school officials. With three, state-of-the-art manufacturing facilities and a global distribution network, Bard’s commitment to quality and product innovation begins with its commitment to research and development. Self-programming energy monitors and green refrigerants With features like self-programming energy monitors, unsurpassed energy efficiency, green refrigerants and the lowest acoustic profile on the market, Bard delivers products that provide tangible solutions for modern school facilities. Already impressed from their previous working experience with Bard, Triumph Modular wanted to incorporate the Quiet Climate 2 into their green modular design. “Building green is good for the environment, good for the wallet and good for the occupants of the building,” said Cliff Cort, adding, “And Bard’s HVAC unit is a big factor in why the Relocatable Green Modular Classroom performs as well as it does.” Green modular design Bard’s HVAC System in the Relocatable Green Modular Classroom Unit contributes to its high energy efficiency According to an independent third party analysis, the green modular design provides a 68% reduction in heating energy and a 49% reduction in cooling energy, most of which can be attributed to Bard Quiet Climate 2. An efficiently designed HVAC system is perhaps the single largest building component that can influence a building’s sustainability. Bard’s HVAC System in the Relocatable Green Modular Classroom Unit contributes significantly to its high energy efficiency and quiet, almost undetectable acoustic profile (37 bBHL) within the classroom. Quiet-Climate 2 heat pump Bard’s Quiet-Climate 2 heat pump is the most innovative wall-mount HVAC equipment ever made. Designed specifically to provide superior energy efficiency and quiet operation in classrooms, the Quiet Climate 2 uses green refrigerants and provides operating sound levels that are 20 to 35 times quieter than a standard wall-mounted heat pump. Bard’s Quiet Climate 2 can provide the following features: Higher energy efficiency and greater comfort through step-capacity technology Unmatched acoustical performance Sound levels vary with applications and construction techniques, but integrated operating sound levels as low as 35 dbA have been achieved when combined with Bard Quiet-Climate acoustical accessories Improved ventilation and Enhanced IAQ Continuous blower operation – without noise – keeping fresh air constantly in the classroom Optional UV lighting which keeps the coils free of bacteria and mold Enhanced filtration capabilities A one-piece factory unit designed for fast installation and easy servicing Additional sound curbing accessories including, an isolation curb and return air and supply air plenums The Carroll School Serving over 75 communities around Lincoln, Massachusetts, The Carroll School was founded in part by Dr. Edwin Cole who wanted to provide a special school for children with language-based learning challenges. The Carroll School supports nearly 300 students, in grades 1 – 8, with a 3.4 student to teacher ratio using multisensory and individualized teaching methods for specific learning needs. Progressive by nature, The Carroll School’s thriving community brings children together in an environment that values their differences and remediates their learning difficulties. “Cliff Cort, a Lincoln resident and friend of the school, approached us with the idea to replace one of our existing modular building with the green modular design,” said Margaret Gebhard, Director of Finance and Operations at The Carroll School, adding “Our existing modular space was not a popular one with either faculty or students due to its poor lighting, sound characteristics and overall appearance.” Occupancy sensors and vestibule The classroom incorporates many unique green components, such as formaldehyde-free, low VOC paints Things changed when teachers, students and administrative personnel moved into the Relocatable Green Modular Classroom for the first time. The classroom incorporates many unique green components, including formaldehyde-free, low VOC paints and coatings that reduce off-gassing, occupancy sensors that conserve energy by turning the lights off, when people come and go, a vestibule that safeguards the inside from inclement weather while buffering outside noise and helps retain heating and controlling levels for its green and virtually silent HVAC system – the Quiet Climate 2. Enhancing schools’ energy efficiency Margaret adds, “The Relocatable Green Modular Classroom is truly amazing and smart to incorporate into any schools modular planning, we’re quickly approaching our original 3 year leasing agreement with Triumph and I see us keeping the Relocatable Green Modular Classroom around for many more years to come.” She further stated, “It has the best lighting, best HVAC system, and is the most energy-efficient building on our campus, which is why it’s also the most coveted space on our campus. Now we can not only say our kids here are special but now they have a truly special and smart environment in which to learn.”
Tuscumbia, Alabama was first settled in 1815. Originally the site of a Cherokee Indian village, Tuscumbia was also home to the first railroad west of the Allegheny Mountains. Today, Tuscumbia has retained its original charm. With a population of just over 9,000, Tuscumbia also enjoys one of the best school systems in the state of Alabama. It is this singular desire to support its rich educational system which prompted Tuscumbia’s City Board of Education to pursue a plan to remodel two of its more than 40 year old school buildings. chilled water HVAC systems It was decided that one central air handler also needed to be installed in each building “We wanted to give our students a comfortable environment in which to learn and recognized that we had a number of things that needed to be updated, including both schools chilled water HVAC systems, and we had to do so within a budget with no margin of error,” said Royce Massey, Superintendent, Tuscumbia City Schools. Since new building codes require that a certain amount of fresh air be delivered to each classroom based on the number of occupants, it was decided that one central air handler also needed to be installed in each building. To help with the renovations, Tuscumbia’s School Board hired Parker Architects who in turn hired Paul Smith and Associates. air conditioner units “At first we specified Bard’s standard gas/electric wall mount air conditioner units with an additional roof top make up air unit for each school,” said Paul Smith, PE, Environmental Systems Corporation. “Unfortunately, after final bids were collected from all of the contractors involved, the project came back nearly $200,000 over budget.” Thirty years ago, Bard began solving the comfort needs of schools across the country. Providing wall-mounted heating and cooling equipment, Bard’s products offer a combination of quiet operation, patented ventilation packages, unsurpassed quality and dependability that make them the #1 choice by many school officials. provide tangible solutions We also decided to add energy recovery ventilator cassettes and the dehumidification option to each unit" With three state-of-the-art manufacturing facilities and a global distribution network, Bard’s commitment to quality and product innovation begins with its commitment to research and development. With features like self-diagnostics and self-programming energy monitors, Bard delivers products that provide tangible solutions for today’s modern school facilities. After the bids were returned, Tuscumbia’s School Board and Parker Architects realized that they had to find a way to resolve the cost barrier or they would have to forgo the bulk of renovations. energy recovery ventilator “Bard really came through when the bids came back,” said Massey. To solve the problem, John Hayes, who works for the George Wheelock Company - one of Bard’s distributors in Alabama - proposed eliminating the two central make up air units and adding features to the Bard WG units that would allow each to provide fresh air to each classroom. “It required some re-engineering of the units on Bard’s part,” said Hayes. “We also decided to add energy recovery ventilator cassettes and the dehumidification option to each unit.” These features would allow each unit to pre-treat the outside air - removing heat and moisture in the summer, adding heat in the winter - and also adding dehumidification, allowing each unit to control humidity in each space. WG Series Wall Mount The WG Series is designed to be mounted on the exterior wall surface of the classroom – fully engineered to be quiet, comfortable, aesthetically pleasing and secure. All of Bard’s WG Series units are designed to meet or exceed federal standards with easy installation features that make servicing fast and simple. Bard’s WG Series units provide the following features: A one-piece factory unit with individual room climate control Optional ventilation packages including energy recovery Controlled dehumidification Simple utility hookups Integrated energy recovery ventilator Easy installation, maintenance and service no additional installation costs Because of Bard’s initiative and everyone’s willingness to work together, we were able to complete the product" “Bard’s willingness to come forward and work towards a solution helped to save the project,” said Brad Bernard, Parker Architects. By eliminating all of the ductwork and subsequent demolition of each hallway ceiling, as well as changing the lighting, wiring and plumbing within the ceiling, Bard saved the Tuscumbia School Board over $300,000. “As part of the savings, there were no additional installation costs because the new features came Bard factory installed with each unit,” said Smith. Bard’s experience working with school systems around the country helps them design manufacture and support the best HVAC system currently on the market. traditional HVAC systems Not only can Bard save its customers money on the installation of traditional HVAC systems, Bard’s units, like the ones installed in Tuscumbia, can save their customers money on their maintenance costs because they are simple to maintain and service. “It’s win-win for everyone involved,” said Massey. “Because of Bard’s initiative and everyone’s willingness to work together, we were able to complete the product, on time and within budget - allowing our students to get the best education in an environment that’s comfortable and one that fosters their hard work and creativity.”
Few buildings demand stricter environmental controls than a library, given the potential for damage caused by temperature, humidity, light and pollutants. To preserve its precious collection more effectively and efficiently, the National Library of Scotland called in Trend Control Systems’ long-term partners, Craigalan Controls (CCL), to conduct a comprehensive BEMS upgrade. The National Library of Scotland, first established in 1925, is a major European research library based in the center of Edinburgh. With a collection of more than 30 million items, it is an information treasure trove for Scotland’s knowledge, history and culture. As the Library grew, however, so did the demands on its BEMS technology. Delivering enhanced environmental controls “As we asked progressively more of the system in terms of both performance and usability, an upgrade became increasingly urgent,” says the Library’s Head of Estates, Ian Symonds. “We worked with the CCL team to plan a series of innovations that would deliver enhanced environmental controls and energy savings, whilst meeting the inevitable funding constraints of our business”. The task was to update a legacy, closed protocol BEMS system which required manual monitoring and data downloads with the latest Internet of Things (IoT) technology. Fortunately, Trend equipment enabled CCL to offer a solution that could extend the Library’s existing BEMS infrastructure without any detrimental effects to its irreplaceable collections. Providing real-Time analytics The graphics demonstrate proactive energy optimization and control of global rate changes “We proposed a phased upgrade from the legacy 963 Supervisor system to Trend’s latest IQ™VISION platform,” said CCL’s Managing Director, Craig James. “Thanks to its full backwards compatibility, connection between the two was seamless. With IQ™VISION, the Library now has a single interface providing real-time analytics via the cloud and allowing enhanced integration with environmental controls, lighting systems, CCTV, fire and intruder alarms,” he added. The upgrade from 963 to IQ™VISION includes the creation of new Analytic Dynamic Graphics. The rich graphics suite provides a dynamic, analytical overview of each area, whilst monitoring temperature and humidity conditions, along with energy usage. The graphics demonstrate proactive energy optimization and control of global rate changes – which are all part of a demand driven response strategy to enhance site performance and help visualize the energy savings /CO2 reductions. Real-Time graphic representations Critically, IQ™VISION software also facilitates the integration of data from a pioneering trial the Library has undertaken with Heriot Watt University - predicting and responding to future weather patterns. The researchers’ algorithms have been developed to add future planning to the system’s broad range of data sets, thus enhancing BEMS performance over time. Thanks to the new platform, energy use and humidity levels are now managed to extremely fine tolerances and rapid analysis is made far easier through real-time graphic representations. The technology allows heating and cooling to be used as efficiently as possible. As a result, the Library has achieved energy savings of £343,000 - a ten-fold return on their initial investment - through a 9% reduction in energy use. They have also seen a 32% reduction in their facilities’ greenhouse gas emissions, allowing the Library to reach the government’s carbon emissions 2020 level four years early. Achieving unprecedented results The project has received widespread industry recognition, including the FM sector’s top honor “Not only have we seen huge savings, we also know we’re fully compliant with the relevant standards and can manage the environment for the Library’s collections and our guests far more effectively – both today and in the years to come,” said Ian Symonds. “The results have far exceeded our expectations, in large part thanks to CCL and Trend’s technology, which has enabled us to think differently, control differently, and achieve unprecedented results,” he added. The project has received widespread industry recognition, including the FM sector’s top honor, when it was declared Overall Winner of the 2019 PFM Partnership Awards. Its success has also led to the Scottish Government recommending that the National Library of Scotland’s practices be applied to public sector facilities throughout the country.
