Thermo King, by Trane Technologies, a global climate innovator, has expanded its portfolio of temporary storage solutions that can meet the unique requirements of global pharmaceutical companies developing COVID-19 vaccines. Thermo King is the global provider of intelligent end-to-end temperature-controlled cold chain solutions. Pharmaceutical companies in final-stage clinical trials anticipate they will require strict temperature controls to safeguard their products - down to temperatures as low as -70 degrees Celsius. Thermo King’s solutions can enable these companies and their distributors to ensure the efficacy of their products through the entire cold chain - from air transport to marine, rail, trailer, last-mile delivery and at storage points along the way. Cold Storage Solutions According to the World Health Organization, nearly 20 percent of temperature-sensitive health care products are damaged during transport, and 25 percent of vaccines reach their destination in a degraded state due to breaks in the cold chain. “Considering the urgent, global need for a COVID-19 vaccine, the world can’t afford breaks in the cold chain.” said Dave Regnery, President and Chief Operating Officer of Trane Technologies. “Our new Cold Storage Solutions can maintain temperatures of -70 degrees Celsius for an extended period of time, can be leveraged to help reduce degradation of a vaccination, and most importantly, could prevent vaccine ‘deserts’ or lack of accessibility.” temporary storage solutions Thermo King offers storage solutions that can substantially extend the life of dry ice, or eliminate the need altogether Thermo King and its worldwide partners can offer temporary storage solutions that maintain a set point down to -70 degrees Celsius, and can ensure end-to-end temperature control, security and traceability through state-of-the-art telematics. Additional storage solutions include refrigerated trailers, containers and portable cubes that can easily be scaled and repositioned to other locations as demand changes. In addition to launching Cold Storage Solutions, Thermo King has helped customers identify ways to maximize the range of dry ice, which is often used in vaccine transport and storage but has certain limitations. A container using dry ice to keep a product frozen may require re-icing if it sits for an extended length of time or is exposed to extreme ambient weather. Thermo King offers storage solutions that can substantially extend the life of dry ice, or eliminate the need altogether. temperature-Sensitive vaccine “We have been engaging pharmaceutical and transport companies, policymakers, regulators and other industry partners to discuss ways to strengthen the cold chain,” said Regnery. “We know that we can help mitigate risk - we have a long history in cold chain expertise, and are actively working to innovate and address the complexities and potential challenges of the mass distribution of a temperature-sensitive vaccine.”

As a Managing Director of a company that provides temperature and humidity solutions to predominantly the warehousing and industrial sectors, I thought I would share my dilemma that I’m sure other business owners and managers also face. I don’t pretend to know the answers, but thought it might be worth sharing some of the considerations that I’m facing in whether to reshape, recruit and build or hunker down until the World, Europe and the UK offers some sort or predictability. I promise to not refer to ‘new normal’, masks or social distancing as this is extensively covered elsewhere. Context Our business has seen steady growth in the past 5 years, as a result of our efforts to create and retain relationships with customers who value our offer. Our focus has always been to offer solutions to large scale complex HVAC projects. We invest heavily in intellectual talent sponsoring PhD and MSc students, to keep us on our toes and develop leading edge solutions. We also feed off each other and our network of equally talented suppliers. My dilemma as Managing Director is do I continue our ambitious Research & Development (R&D), IP and Business Development or throttle back and take a cautionary approach until the economy offers a more certain platform? ‘Fortune favors the brave’ they say, but when you have a good business and employees look to business managers to ensure their livelihoods, how brave is brave? The Dilemma Immediate transactional or contractor resources are easy to obtain with the right screening and due diligence Immediate transactional or contractor resources are relatively easy to obtain with the right screening and due diligence, but for more developmental strategic roles, do you recruit in an emerging post pandemic, catastrophic employment forecast, that to in a mid/post Brexit world? From my personal perspective, it boils down to attitude, communication, enthusiasm and buy-in from everyone in the company. Nothing new there, but it feels that the stakes are higher so confidence is key. Do we or don’t we? Inaction is the riskiest response to the uncertainties of an economic crisis. Rash or scattershot action can be nearly as damaging. Rising anxiety (How much worse are things likely to get? and for how long is this going to last?) and the growing pressure to do something often produces a variety of moves that target the wrong problem or overshoot the right one. Within the world of HVAC, changes to legislation, environmental considerations, technological changes and research and development might be slowed or influenced, but won’t stop as a consequence of the immediate economy, which is a good thing. Recruiting on a need basis Many companies recruit when needed, to fill a vacant position or when a large project demands more manpower than the current headcount supports. This approach is obvious and addresses immediate transactional and resource needs. Using headcount as a KPI for growth, at a glimpse may illustrate positivity, but may be signaling a stop gap and may not be a true indicator of strategic growth. Of all the things I have observed over the last 5 months, reading the news, talking to colleagues and peers, a few things have stuck out for me, such as how companies have treated their employees, customers and suppliers, how creative and flexible some big organizations have been in responding to market changes and demands and how, despite uncertainty, their core business skills, intelligence and ability enabled them to prosper in a new and unforeseen environment. Finally, how companies will be remembered post crisis. Robust business planning The ability to respond quickly to market changes relies on creativity and attitude My belief is that those companies that have and continue to float to the top had the key ingredients of a successful business, enabled by capable enthusiastic talent that were given the opportunity to shine. These people weren’t hired to fill a stop gap, but rather these people were hired as part of a robust business plan. So, ‘do we or don’t we?’ Our philosophy at Jet Environmental Systems is to have a solid platform, identify future markets, trends and technologies and hire the absolute best people that we can to get us there. Recruitment in our business is a process that supports our strategic development and so for us our answer is yes, have confidence and continue to invest in the best talent. The ability to respond quickly to market changes relies on creativity and attitude with support from equally enthusiastic management who create the opportunity for individuals who present this talent to grow. Conclusion I hope the thought process I’ve shared has been useful, for me it has been a checkpoint in whether our choice of investment in people is right, not just now but in all situations. For me, it’s a resounding yes! I think we will create opportunities by having vision and giving people opportunity.
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.
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.

Infinitum Electric, creator of the breakthrough printed circuit board (PCB) motor, has announced the first product shipment from its revolutionary line of IoT-enabled electric motors to Comefri USA, a renowned HVAC fan original equipment manufacturer (OEM). Twenty-five trillion kilowatt hours of electricity are consumed per year, of which 45 percent is consumed by electric motors. This leaves a significant opportunity for many industries, including HVAC, to develop or replace machines using traditional motors with more efficient electric motors, which consume far less energy. Infinitum Electric is enabling this transition with its IEs series of motors. IoT-enabled IEs series electric motors Infinitum Electric’s IEs205 10 horsepower electric motor will be used by Comefri to power more efficient, space-saving commercial plenum fans, used in commercial and industrial buildings to deliver more sustainable heating and cooling airflow, along with helping in fighting climate change. The company’s award-winning electric motors meet the industry’s highest standards for efficiency and are significantly quieter than the competition. By replacing traditional iron and copper wire winding components with an IoT-enabled circuit board, Infinitum Electric motors are not only smaller, quieter and up to 50% lighter, but they have fewer structural requirements than others on the market. Cloud-connected IoT capabilities The motor’s cloud-connected IoT capabilities enable remote monitoring of key operational data Additionally, the motor’s cloud-connected IoT capabilities enable remote monitoring of key operational data, such as power, speed and temperature, for superior smart building and HVAC equipment intelligence.

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.

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.”
Newberry, South Carolina is a town with a rich historic personality. Settled in 1745 by Scotch-Irish, English and German immigrants, Newberry became a leading cotton market with the coming of the railroad. Today, Newberry has retained and preserved much of its original small town charm. Its downtown business district and residential streets are lined with historical buildings and Antebellum homes - there are, in fact, several blocks in which every building is listed on the National Register of Historic Places, including its world famous Opera House and the Old Court House. part of A heritage It was this singular desire to preserve its traditions that prompted Newberry to take a similar approach when considering what to do with its now-closed, eighty-year-old Newberry High School. Thoughts of tearing it down to make way for a new facility simply weren’t acceptable. Especially so to Newberry’s 11,000 residents and alumni like retired Principal Phil Spots and lifelong resident Wirt Jennings. The job of renovating a building that had been closed for several years fell into the hands of Rufus Rogers “Newberry High School was central to our community, it’s a part of our heritage, and it’s where I, and many other Newberry residents, had the best times of our lives,” said Phil Spots, Class of ’54 and retired principal. The job of renovating a building that had been closed for several years fell into the hands of Rufus Rogers, Newberry County Schools Director of Buildings and Grounds. solving comfort needs Clearly up to the task, Rufus is a retired Army Colonel and graduate of Mechanical Engineering from Clemson University. His challenge was to recreate an old school with modern features - to restore what could be seen and modernize what couldn’t be seen. Newberry High School was to be transformed into Newberry Elementary. Features to restore included the exterior façade and glass, interior marble and terrazzo floors, and the school’s heart - its well worn pine floors. Unseen updates to be added included full climate control (heating, cooling, ventilation and dehumidification), electrical, data cabling, media network, and security. The trick was in making it look like it all belonged as part of an original, historical structure. Why Bard? Thirty years ago, Bard began solving the comfort needs of schools across the country. heating and cooling equipment 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 by many school officials. With three state-of-art manufacturing facilities and a global distribution network, Bard’s commitment to quality and product innovation begins with its commitment to research and development. Bard delivers products that provide tangible solutions for today’s modern school facilities With features like self-diagnostics and self-programming energy monitors, Bard delivers products that provide tangible solutions for today’s modern school facilities. Newberry was already familiar with Bard Manufacturing and its products - the school system has portable classrooms with Bard units in them that are 35 years old. provide tangible solutions “Our experience with Bard’s units and their experience working with schools, plus the ease with which their products can be serviced, make Bard an easy choice,” said Rogers. Darrel Bradfield, school HVAC specialist and Class of ’74 agrees with Rogers’ assessment. “Bard’s units are easy to service, simple to operate, information is always available, and the units are easy to maintain. Bard delivers products that provide tangible solutions for today’s school facilities, whether they are new buildings, renovations, or preserved historic landmarks.” Water Source Heat Pumps Working together with the architectural firm recommended by Rogers and hired by the Newberry District and School Board - McMillan Smith and Partners - Bard was able to provide the perfect solution. “Our first phase of the restoration was the exterior; to maintain an historical perspective we knew we did not want any penetrations through the exterior wall,” said Donnie Love, McMillan Smith and Partners. We really liked the Bard system and won’t hesitate to use it on a similar application, or a new school" “When Wade Crow, Wade Crow Engineering, suggested Bard’s QTEC Water Source Heat Pumps, I knew the units were perfect for the application - we really liked the Bard system and won’t hesitate to use it on a similar application, or a new school,” added Love. energy recovery ventilator QTEC - The Quiet “Hidden” Technology The 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 Dehumidification units “Our school has retained its historic charm and character and will do so for generations to come,” said Doris Coggins, a 27-year teaching veteran. “I also love the fact that the AC is very quiet.” “We have known Bard for years and Bard’s Water Source Heat Pump/Dehumidification units were the perfect application for this restoration project,” said Rogers. “We’re glad to have worked with a company with an established reputation for creating a comfortable environment for our school.” energy efficient HVAC systems “It’s not simply the building Bard helped us restore, they helped us preserve some of our residents’ fondest memories of what it was like to grow up and learn more about their world, its people, and our country’s rich history, which began in places like Newberry, South Carolina” said Leila Caldwell, Principal of Newberry Elementary School. Bard’s experience working with school systems around the country helps them design, manufacture and support the best HVAC system currently on the market. Not only do Bard’s units operate quietly, they’re also energy efficient - and they can save customers money on their maintenance costs because they are simple to maintain and service.
