Manufacturers continue to make improvements in heat-pump technology, including higher efficiencies, contractor-friendly designs, and innovative extras like two-stage compressors that allow them to run at lower speeds and cut down energy use and homeowners’ bills. Below is a sampling of six of the latest products to hit the heat pump market. Nortek Global HVAC introduced the W-Series of air conditioning and heat pump equipment for residential and light commercial applications, completing its redesign of Gibson®, NuTone®, and Frigidaire® branded 1.5- to 5-ton, single-phase air conditioning units and heat pumps. The redesign offers contractors a ‘good-better-best’ strategy (the premium F-Series, the mid-range E-Series, and the economically-priced W-Series) to accommodate varying consumer price ranges. Coil-Protecting wire guard The W-Series heat pump is available in 14- and 16-SEER models. Standard features include Copeland scroll compressors and a liquid line filter-drier for field installation in an accessible position to facilitate easy periodic change-outs. It also has a coil-protecting wire guard that adds cabinet structural integrity and holds a plastic mesh in place to safeguard against hail and accidental contact damage, plus an anti-corrosive polymer drain pan with more drainage holes to eliminate potential standing water. On the unit’s exterior cabinet, above the refrigerant access port, is a weather-proof QR code called ‘Charge Me’ that can be scanned to access Nortek’s charge assist tool. “The new W-series of heat pumps recently introduced by Gibson, Frigidaire, and NuTone features a high-tech way to charge,” said Dave Garvin, product manager, Nortek Global HVAC. Variable Speed Heat Pump Rheem’s next generation Prestige® heat pump harnesses the power of the new EcoNet Smart Thermostat “The proprietary website helps account for subcooling, fixed orifices, thermostatic expansion valves, ambient temperature at time of charging, lineset length, and other variables that can trip up contractors when charging any heat pump brand.” The Rheem® Prestige® Series EcoNet®-Enabled Variable Speed Heat Pump features a contractor-friendly design, which means expanded valve space and triple service access, for fast and easy install and repairs. Corner-service access allows optimal access to internal components, while individual louver panels speed coil cleaning and cabinet reassembly. Plus, Rheem’s next generation Prestige® heat pump harnesses the power of the new EcoNet Smart Thermostat, which provides control, monitoring, and one-touch alert capability. Proper installation and reduced time “Rheem’s Prestige Heat Pump powered by our EcoNet Smart Thermostat keeps contractors in control,” said Ryan Teschner, product manager for Rheem Mfg. “From real-time alerts and system notifications to a charge mode capability, which allows for proper installation and reduced time on the job, Rheem’s heat pump increases job site efficiencies and reduces labor costs for contractors.” The hybrid electric Voltex® from A. O. Smith has an energy factor (efficiency based on the amount of hot water produced per unit of fuel consumed over a typical day) of 2.3, and is Energy Star® qualified. “Heat pump water heaters use electricity to pull heat from the surrounding air rather than generating their own heat,” said Brandon Stepanek, national field marketing manager at A. O. Smith. Reducing greenhouse gas emissions Carrier’s Hybrid Heat systems automatically switch between electric and gas heating “This means that they can be a logical choice for dedicated green home builders interested in enhancing energy efficiency. Because a heat pump water heater uses energy efficiently, it can save customers up to 10 percent on energy bills, which adds up to thousands of dollars over the life of the water heater,” he continued. “The significant reduction in electricity use also has a direct effect on reducing greenhouse gas emissions.” Carrier’s Performance™ Series heat pumps offer a range of efficiencies that start at 14 SEER and reach 17.5 SEER and up to 9.5 HSPF. Combining a gas furnace, an electric heat pump, and a compatible thermostat, Carrier’s Hybrid Heat systems automatically switch between electric and gas heating to optimize the efficiency of each fuel source, helping defend homeowners against utility cost fluctuations. They have Energy Star designation. Carrier indoor furnace “Our microtube coil technology saves space and provides lasting comfort with its corrosion-resistant construction,” the company stated. “In addition, some models include innovative extras, like a two-speed compressor for added benefits like higher efficiency and even, consistent comfort. When installed with a custom-matched Carrier indoor furnace or fan coil and a Côr® Wi-Fi® thermostat, our two-stage heat pumps can operate on low stage up to 80 percent of the time to keep airflow and temperatures even and consistent while adding humidity control during cooling operation.” Heating operation is rated down to minus 5˚F outdoor temperature Fujitsu General America Inc. recently debuted the RGLX Series, three medium-static pressure ducted indoor units for the single-zone Halcyon mini split line. They have sufficient static pressure to heat or cool a whole house. Heating operation is rated down to minus 5˚F outdoor temperature.

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.

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.
As the Internet of Things (IoT) has evolved, the need has become obvious for stronger unity among brands and ecosystems to enable products within smart environments to work together more easily. Working to serve that need is the Zigbee Alliance, which seeks to promote collaboration in the Internet of Things by creating, evolving, and promoting universal open standards that enable all objects to connect and interact. Their effort took off when Amazon, Apple, Google and the Zigbee Alliance announced an industry working group in December 2019 to take the “best of market” technologies from leading smart home standards, portfolios and ecosystems and to develop a “super spec” that will be open, inclusive and a significant industry shift in the smart home market. smart home automation system “Zigbee Alliance has been for a while now working on openness and interoperability, which has led us to the Project Connected Home over IP (CHIP), which is looking to unify the environment, under one technology, one certification program and one logo,” says Chris LaPré, Zigbee Alliance’s IoT Solutions Architect. “It really does fuel IoT possibilities, whether in HVAC or any other sectors.” There is a stronger need for unity, which is why we are developing Project Connected Home over IP" Project CHIP is a royalty-free connectivity standard that unifies brands and ecosystems into a single smart home automation system that operates any other technology based on Internet Protocol (IP). The intent is to simplify product development for device manufacturers, broaden consumer choice, and to ensure easy discoverability, deployment and engagement to fuel connected living. unifies that environment “We have noticed that, as the IoT has evolved, there is a stronger need for unity, which is why we are developing Project Connected Home over IP,” says Jon Harros, Zigbee Alliance’s Director of Certification and Testing Programs. “It fits with the Zigbee Alliance’s goal to unify systems, and to focus on everyone using the same application at the top. It unifies that environment, whether you are integrating your system with Amazon Echo devices or connecting to Google Home.” Participating in development of Project CHIP are 125 companies of various types from around the world working together with more than 1,100 of their experts serving across sub-committees to formulate specifications and fine-tune the project. Although the technology is being developed for the home market, the specifications have been formulated with an eye toward expanding into the commercial market in the future. home system technologies Development of open, interoperable systems provides greater freedom for consumers to choose among the many technology choices on the market, without being tied to a single brand or ecosystem. Zigbee Alliance certifications and memberships span the globe, with roughly a third in Europe, a third in North America and a third in Asia. Involvement in Europe is slightly higher than the other regions. Alliance members represent manufacturing sites all over the world. Project CHIP is a newer initiative of the Zigbee Alliance, which previously developed Zigbee Pro to enable home system technologies to operate using IEEE 802.15.4 wireless signals on the 2.4GHz radio band over a self-healing true mesh network. The original Zigbee protocol is used for many applications around the world, including HVAC. smart temperature devices HVAC developers who have specific use cases should have a look at the work of the alliance Members of the Zigbee Alliance include HVAC companies such as Lennox, Stelpro and Belimo, among others. Carrier is a recent company that has joined the Zigbee Alliance. Smart thermostats, including the popular Ecobee, have used the Zigbee protocol. More than 100 different devices have been certified as thermostats or smart temperature devices. Harros urges other HVAC companies to become more involved with the Alliance. “We want them to come and have a look to see what we are doing and get involved,” he says. “This is where the work is being done as we unify the environment and bring together all the devices and ecosystems to work together.” HVAC developers who have specific use cases should have a look at the work of the alliance, he adds. certification transfer program Among the strengths of the Zigbee Alliance are years of experience certifying products, which includes testing them and confirming that they comply with the promoted specifications and functionality. The specifications are open standards that are developed in cooperation with all the companies that are Zigbee Alliance members. Another route is the certification transfer program, in which a company chooses a certified white-label product, becomes a member of the Alliance, and then rebrands the product while retaining the certification. “It helps them get products on the market quickly while they build their own knowledge base,” says Harros. "All our work is focused on standardizing the behavior and functionality of products and making sure everyone is following the same standard to get interoperability,” says Harros. “Members all contribute to the standards.”
Panasonic has conducted research that verifies that hydroxyl radicals contained in water can inhibit the novel coronavirus (SARS-CoV-2). The nano-sized electrostatic atomized water particles are generated by applying high voltage to moisture in the air. The patented technology - brand-named 'nanoe X' - is already used for air and surface purification in Panasonic’s air conditioning systems. The research suggests that the technology might be useful in fighting the coronavirus that causes COVID-19 in addition to its use to inhibit odors, pollutants, allergens, and other viruses. The research was conducted in collaboration with Mayo Yasugi, Associate Professor, Department of Veterinary Science, Graduate School of Life and Environmental Sciences, Osaka Prefecture University. Here is a clarification from Panasonic: "While Panasonic makes a wide range of products that generate these type of free radicals, none of these products has been tested for efficacy in the inhibition of the SARS-CoV-2 virus on surfaces or in the air. We continue to monitor the latest research and study the matter, and in the event that scientifically sound research shows our product/s to be effective in helping to inhibit this virus, we will work with the appropriate regulatory bodies to ensure all information is validated." inhibit pathogenic microorganisms Hydroxyl radicals contained in water are characterized by being strongly oxidative and highly reactive. Panasonic has conducted research on the technology since 1997 and has verified its effectiveness to inhibit pathogenic microorganisms (bacteria, fungi, viruses) and allergens, breaking down PM2.5 components that have adverse effects on the human body. In 2012, Panasonic conducted a virus clearance test with a third-party organization and confirmed the effectiveness of each of four categories in terms of biological characteristic. Based on the result, Panasonic announced that “hydroxyl radicals contained in water” technology could be expected to have an inhibitory effect on new viruses. evaluate product performance The virus infectious titer was measured and used to calculate the inhibition rate SARS-CoV-2 is an example of a new type of virus, and now testing (in July 2020) has confirmed that the hydroxyl radicals contained in water do in fact have an inhibitory effect, according to Panasonic. The testing was carried out in a closed laboratory environment and was not designed to assess efficacy in uncontrolled living spaces. The comparative verification was conducted in a 45L test space that contained the novel coronavirus with and without exposure to hydroxyl radicals contained in water. Over 99% of novel coronavirus activity was inhibited within three hours. Panasonic emphasizes the verification was designed to generate basic research data and not designed to evaluate product performance. A piece of gauze inoculated with the virus solution was placed in a petri dish and exposed to hydroxyl radicals contained in water for a pre-determined time. The virus infectious titer was measured and used to calculate the inhibition rate. creating healthy environments The same test was performed three times to confirm reproducibility. The reactive components generated by “the electrostatic atomized water technology” are “wrapped and contained” in the water particle, so the substances have a longer life and are delivered to wider areas than usual ions. Panasonic says it will continue to pursue the potential of “hydroxyl radicals contained in water” technology to address possible risks associated with air pollution such as new pathogenic microorganisms, with the aim of creating healthy environments for people around the world.
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
In the spring of 1999, Wilkes County, North Carolina had a difficult and challenging problem to contend with. With an ever-increasing student population the school system faced the daunting task of building four new middle schools to improve its countywide school facilities. Committed to excellence in teaching and to the belief that all students can learn, Wilkes County Schools strive for student success through a partnership of school, home and community. Building on funds already allocated by the State Board of Education, Wilkes County Schools received approval for up to $24 million in additional funding from the County Commissioners. Because of the needs of the growing middle school student population countywide, it was decided that one school would be built in each of Wilkes County’s four school districts – Central, West, North and East. Budget constraints Wilkes County Schools turned to the heating and cooling expertise and experience of the Bard Manufacturing Company But the challenges didn’t end with the County’s approval to build. Staying on budget would be an even greater challenge, given all of the amenities, and opportunities for greater learning that the school system wanted to provide for its students. Aware of the impacting impression a new school has on individual students, Wilkes County remained determined to build its schools so they were aesthetically pleasing, both inside and out, and comfortable throughout every season. That’s when Wilkes County Schools turned to the heating and cooling expertise and experience of the Bard Manufacturing Company. Wall-mounted heating and cooling equipment 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. 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. With features like self-diagnostics and self-programming energy monitors, Bard delivers products that provide tangible solutions for today’s modern school facilities. Bard’s Contribution What we liked best overall about the Bard units was having control over the environments in each of our classrooms" Wilkes County Schools were already familiar with Bard Manufacturing and its products, having successfully installed and operated Bard’s previous generation of wall-mounted units nearly 15 years ago in its other school facilities. “What we liked best overall about the Bard units was having individual control over the environments in each of our classrooms,” said Phil Couch, Maintenance Director and Assistant Superintendent for Wilkes County Schools. "When Wilkes County first suggested Bard units for the design, we were skeptical – we didn’t know a lot about Bard and we were more comfortable using the traditional four-pipe system,” said Frank Williams, Partner, Pinnacle Architecture. “However, now that we’ve seen how Bard units work, we’re comfortable recommending them wherever the incremental design makes sense. Teachers love the control, and we like the simplicity of installation!” Energy efficient Bard first developed its incremental wall-mounted cooling units in 1963. Since that time, Bard has made many advances and enhancements to its units, making them ideal for new schools and classroom renovations. Aware of Wilkes County Schools’ desire to also make their new facilities aesthetically pleasing, as well as energy-efficient and comfortable to learn in, Bard recommended its QTEC self-contained cooling unit. QTEC - The Quiet “Hidden” Technology QTEC units are designed and tested to operate at 20% above federal standards with easy installation features 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 Design for fast installation and easy servicing Sound deadening insulation Simple utility hookups Integrated energy recovery ventilator Controlled dehumidification Wilkes County Schools’ Results Wilkes County opened its four new schools in time for the 2002 fall semester and they were able to do it on budget, thanks to Bard. “Bard’s experience working with school systems around the country helped us design, engineer and install the best system we could have hoped for,” said Couch. “Not only do the units operate quietly, they’re energy efficient. They also save us money on our maintenance costs because we can work on them ourselves with our own in-house maintenance staff.” Comfortable environment And because Bard QTEC units take up less space and are less costly to install over traditional boiler/chiller systems, Bard also helped save Wilkes County Schools $3.5 million on their overall construction costs. Wilkes County Schools then used these savings to fund four computers in each classroom, and three computer labs for each school. “Working together with Pinnacle Architecture, Bard not only helped us create a comfortable environment for our students to learn in, they enabled us to purchase, through savings, additional technology equipment,” said Couch.
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.”
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.”
Situated almost halfway between San Diego and Los Angeles, Perris was a place where sheep casually roamed the valley, and where people discovered what the land had to offer; a moderate climate with rich soil good for farming. But Perris’s sleepy image began to change in the spring of 1886, when it became a stop along the Transcontinental Route of the Santa Fe Railroad. Perris continues to thrive. With a current population of 45,000, and continued population growth over the last several decades, dramatic improvements and expansion have been made to the Val Verde Unified School District. Val Verde, with its 23 school buildings serves a 60-mile radius, including Perris, Moreno Valley and Riverside County, California. To remain flexible in accommodating the number, as well as the individual needs of students, Val Verde employed modular construction techniques with many of its buildings. Prototype classroom Bard began solving the needs of schools by providing wall-mounted heating and cooling equipment These modular units are built off-site, employ a stucco wrap and have a flat roof and a wood floor. Although they are relatively inexpensive to build they do have the unfortunate characteristic in that they can also be noisy. “For a long time we were looking at ways to improve the quality of our building’s construction, and with them their acoustical environment,” said Todd Butcher, Director of Maintenance and Operation at Val Verde Unified School District. This idea led Val Verde to develop its own prototype classroom, one that used a sloped roof with a 4-foot overhang and a concrete floor. This prototype, which would create better sound insulation from outside noise while providing needed shade from the sun, would be used to build the new May Ranch Elementary School slated for opening in 2008. Bard selection 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, patented ventilation packages, unsurpassed quality and dependability that make them a 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. With features like self-diagnostics and self-programming energy monitors, Bard delivers products that provide tangible solutions for today’s modern school facilities. Bard’s Contribution We quickly ascertained that Bard’s Quiet Climate 2 series was the perfect option for what they needed" “In conjunction with our prototype construction, we also wanted to see if we could obtain quieter operating air conditioning units,” said Butcher. “Our ultimate goal was to additionally reduce the overall decibel levels within each of our classrooms.” That’s when Val Verde turned to Geary Pacific, the local distributor of Bard HVAC equipment. “Based upon their needs, we quickly ascertained that Bard’s Quiet Climate 2 series was the perfect option for what they needed,” said Dave Gorman, Head of School Sales for Geary Pacific. Already impressed from their previous working experience with Bard, Val Verde decided to test the Quiet Climate 2 in the single best environment for testing noise levels – Val Verde’s Audiology Laboratory where student’s hearing is tested. “The environment for evaluating our students has improved by at least 200%,” said Randy Lerner, District Audiologist for Val Verde Unified School District. Ambient noise level Since the Bard Quiet Climate 2 has been installed, the overall ambient noise level in the clinic has dropped considerably from 58 dbA to 37 dbA (decibels recorded ten feet in front of the unit). “With the old unit, I used to have to turn it off during a testing session because it sounded like there was a farm tractor outside the window,” says Lerner. “Now students comment on how quiet the lab is – and that’s when the unit is on!” The Quiet Climate 2 provides operating sound levels that are 20 to 35 times quieter than a standard wall-mounted heat pump Bard’s Quiet-Climate 2 heat pump is an innovative wall-mount ever made. Designed specifically to provide quiet operation in classrooms, the Quiet Climate 2 provides operating sound levels that are 20 to 35 times quieter than a standard wall-mounted heat pump. Ventilation and IAQ Bard’s Quiet Climate 2 can provide the following features: A one-piece factory unit designed for fast installation and easy servicing Higher energy efficiency Additional sound curbing accessories including, an isolation curb and return air and supply air plenums Improved ventilation Enhanced IAQ Val Verde’s Results “Bard overwhelmingly proved to us that they are able to help us reduce the sound levels in our school’s classrooms”, said Butcher. “If they can make our audiologist as confident as he is with the Laboratory’s ambient noise level, we know the units will perform just as well in our regular classrooms.” Comfortable environment Val Verde Unified is planning to use Quiet Climate 2 units in its new May Ranch Elementary School Because of its success with the Audiology Laboratory, Val Verde Unified is planning to use Quiet Climate 2 units in its new May Ranch Elementary School. “It’s great that a company like Bard has not only the reputation that they do for making quiet units, but that they also have an interest in helping create a quiet, comfortable environment in which our children can better learn,” added Lerner. Bard’s experience working with school systems around the country helps them design, manufacture and support the best HVAC systems on the market. Bard units operate quietly, are energy efficient and are also able to save customers money on their maintenance costs because they are simple to maintain and service. “Working together with Geary Pacific and Bard, we were able to create an even more quiet, comfortable environment in which our students can better hear and learn in,” added Butcher.
When Tuscaloosa County developed its HVAC wish list for their high school’s new addition, it looked something like this: Reliability, energy savings, installation ease, sufficient ventilation, quiet operation and aesthetics. A tough call when faced with the typical budget restraints facing school districts around the country. The Tuscaloosa County School System’s architect and engineer turned to a combination of Bard 12 SEER “Quiet Climate” wall-mounts and Q-Tec heat pumps, which resulted in comfortable students, an optimized learning environment and satisfied administrators. Q-Tecs and Quiet Climate Q-Tecs were installed inside those classrooms facing the front of the building to enhance the clean, finished look that the architect required. “Quiet Climate” wall-mounts were installed in all other areas of the building. Both models provided the Bard advantage that the school system was looking for when they specified individual room control. Each classroom has its own Bard unit with a built-in ventilation package, which provides each classroom with the specific climate control and outside air it requires, not what’s being determined by a central system. Along with comfort, the Q-Tec and the “Quiet Climate” units provided the additional benefit of low operating sound levels. Both units were specifically designed so teachers would not have to compete with the mechanical sounds often generated by other climate control systems. Maximizing the savings According to Dr. Frank Costanzo, Assistant Superintendent, “We’re very pleased with the performance of the Bard units on this project. Bard was selected for individual room control, energy efficiency – 12 SEER, and quietness of the units.” The school district was especially pleased with Bard’s ability to maximize the savings during the installation process and on-going operations. Installation ease and the fact that the units would not have to be ducted help bring the project’s mechanical costs within budget. Specifying the high efficiency 12 SEER design insured that energy savings would be generated on the operations side for years to come.
