As we look back at 2020, we are all reflecting on the year that was, and what we have learned from it. In the HVAC space, the year provided us with opportunities for growth and change, as we adjusted to our “new normal.” Here’s a look at some of the HVAC trends we see happening now taking hold as we head into 2021. Advancements and applications in indoor air quality - especially in HVAC space (SF / MF / CRE) 2020 was filled with starts and stops with regards to innovation. Covid-19 halted work in some facilities altogether earlier in the year. The pandemic has brought with it a re-energized interest in the air quality around us, especially in the public sector. There has been a newfound imperative in creating indoor air quality solutions that ensure that air is circulated, sanitized and purified to reduce the likelihood of the spread of sickness. This is a massive issue and 2021 will see growing efforts in these areas and the increased introduction of systems that will purify air quality. HVAC building systems Continued push toward energy efficiency (mainly SF but also CRE) Energy efficiency will be an ongoing issue into the foreseeable future. Once we have looked back at 2020’s carbon emission reductions (because fewer people were flying and driving) there will be no turning back. The same can be said for HVAC. Increased efficiency will continue to be an ongoing pursuit in 2021 and beyond. On average, HVAC appliances consume 48% of a household’s total energy usage. The latest generation of smart thermostats that use the newer 410A refrigerant have brought about reduced energy consumption by up to 35% optimizing how HVAC building systems are operated (reducing the possibility of leaving the AC on too long, and when it’s not necessary to use). convenience and energy savings Increase in supply chain management / platform services HVAC services such as those that collect and manage data including HVAC unit age, efficiency and condition at the property and portfolio level will continue to see increased adoption. These convenience and energy savings they provide is being seen in the multi-family and commercial space, especially with some building owners having been grounded by the pandemic in 2020. New construction had a role in expanding interest in HVAC asset tagging and helping it gain traction in the industry The data gathered by these services can be used in the future to predict HVAC system failures with significant accuracy before they happen. The convenience and potential cost savings acquired by implementing these services will continue to push their popularity into 2021. Additionally, it is interesting to note that new construction in 2020 had a role in expanding interest in HVAC asset tagging and helping it gain traction in the industry. Cataloguing HVAC assets ensures the follow up and guarantees that warranty registration holds and can help track future maintenance during a hold. At the time of sale, the current owner can present true data of the maintenance of these systems, which can increase the current value of the property and can also be used as a tool in negotiation. performing regular maintenance Remote monitoring can be the end to end solution that completes the action behind the alert (CRE mainly) Remote monitoring will continue to see adoption in 2021. Service providers will continue to rely less and less on clients identifying and reporting a problem a heating/cooling issue. The complaint from the tenant may come in some hours after the problem actually starts, and then by the time they get a service request completed, several hours more. And by the time the contractor is on the scene, it is likely more time has elapsed. Remote monitoring also results in regular maintenance, extending the lifetime of a HVAC system. By proactively performing regular maintenance, the overall costs of maintaining a system can be reduced by 40 percent, in addition to ensuring that units are always using the least amount of energy necessary. seamless customer experience Consolidation of HVAC services and equipment - the way people buy - turnkey integrated services One stop shopping for HVAC services and equipment gained popularity in 2020 One stop shopping for HVAC services and equipment gained popularity in 2020 and we will continue to see increased traction in 2021. There are many reasons why developers what to buy equipment directly from the manufacturer, such as convenience, working with a supplier because of its reputation, cost and guarantees on product and services. As more developers buy equipment directly, these manufacturers are responding by helping out with mechanical drawings. This process cuts down the supply chain, allows certainty that correct equipment is quoted, and saves money. The HVAC industry is also turning the corner in becoming more proactive in remediating failing assets and contractors are redoubling their efforts to provide a seamless customer experience increasing customer satisfaction for multi-family communities as well as other means of optimization of services that positively impact tenants, helping increase retention. HVAC providers that can manage the entire process from installation, to job request to invoicing, even reporting and tracking for each job, will be increasingly in demand in 2021.
Our world plunged into a new set of uncomfortable norms in 2020. Mere months ago, life for much of the planet chugged along at its customary monotonous pace. Then, without forewarning, an insidious health threat thrust upon us. COVID-19, colloquial for SARS-CoV-2, is a novel coronavirus that originated in China in late 2019. It quickly burned around the globe like a dry brush fire. Not since a hundred years ago has humanity confronted mask wearing and social distancing in efforts to prevent suffering on a pandemic scale. A single COVID-19 viral particle is extremely small at 0.06 microns. This pure form of COVID-19 is not found outside a laboratory and would not survive even if it made its way into the environment. A single sneeze can eject 200 million COVID-19 particles into the airInstead, SARS-CoV-2, when expelled by infected human hosts, is encapsulated by mucus material. Hosts shed airborne viral particles in two modalities: droplets and aerosols. Droplets are about 1 micron while aerosols approximate 0.5 microns. Millions of viral droplets and aerosols are sloughed-off by talking, laughing, coughing, sneezing, singing or simply by breathing. A single sneeze can eject 200 million COVID-19 particles into the air. Portable air purifiers provide a potent tool in the fight to reduce the spread of COVID-19. The selection and deployment of an appropriate purifier are instrumental in lessening airborne viral droplets and aerosols. Advanced purification units can sterilize air as well as trap pathogens. This best-of-both-worlds approach to disease prevention is vitally important. HEPA Filtration An air purifier must have a medical-grade HEPA filter if the goal is trapping airborne pathogens. HEPA filters remove 99.97% of particles down to 0.3 microns in size. HEPA has different levels. The H-values of HEPA range from H10 through H14. Medical-grade HEPA is H13 or higher and provides filtration efficiencies of 99.95% of 0.1 micron-size particles per liter of air. As a result, medical-grade HEPA is highly effective in COVID-19 droplet and aerosol elimination. Clear Air Delivery Rate Clean Air Delivery Rate (CADR) is a critical metric of a purifier's ability to remove particles of a given size and is measured in Cubic Feet per Minute (CFM.) This drastically differs from a CFM metric alone. CFM as a standalone value demonstrates only the volume of air moved through a system without regard to particle removal. CADR is a compulsory and precise method of comparing air purifiers in a standardized manner. Choosing a purifier with the highest CADR is always preferable. Experts recommend devices with a CADR that moves the total air volume of a room through the purifier 5 to 6 times per hour. Portable air purifiers provide a potent tool in the fight to reduce the spread of COVID-19 Ultraviolent Light Ultraviolent Light (UV) is a powerful sterilization strategy. UV is used in medical settings worldwide for this purpose. While utilizing UV in a purifier is advantageous, selecting a device with UV in 254 nm wavelength is paramount. UV outside of this wavelength can excite oxygen into creating harmful ozone molecules consisting of 3 oxygen atoms. Cutting-edge air purifiers have 254 nm UV bulbs formulated with doped quartz. Such doping precludes secondary harmonic UV wavelengths from radiating from the bulb. UV is an invaluable element of air decontamination if ensured UV is 254 nm and doped bulbs are utilized. Photocatalysis Some air purifiers employ photocatalytic Titanium Dioxide (TiO2) membranes to complement their UV. The resulting photocatalysis dramatically enhances the sanitizing effects of UV. A TiO2 photocatalytic reaction under UV radiation provides additional disinfection pathways in addition to UV directly acting upon pathogens. Thus, both direct UV and photocatalysis provide exceedingly effective methods of microorganism degradation and destruction. Other Technologies Other technologies are found in purifiers, such as sophisticated filters to thwart VOC/TVOC compounds and negative ion generation. Negative ions have antibacterial properties, including marked reductions of acinetobacter transmission. Also, negative ions have the beneficial capacity to precipitate airborne PM1.0 and PM2.5 particulate matter, which are impurities that affects health. Advanced purification units can sterilize air as well as trap pathogens With the COVID-19 age upon us, portable air purifiers provide enormously powerful weapons in protecting the health of persons inside enclosed spaces. Air purification coupled with other air quality measures -- such as ensuring a suitable amount of outside air exchange, air agitation with fans and upgrading existing HVAC filters with MERV-13 -- present an effective and comprehensive approach to health and safety.
Having spent the last few months working from our sofas, dining tables and ironing boards, many of us have become accustomed to the world of remote working. But we’ve now arrived at a point where many businesses are starting to reopen their doors or have plans to do so in the near-future. Employers will be hoping that a return to work will prove productive, reinvigorating the workforce and driving growth. To this end, however, they will need to instill confidence by demonstrating how they can keep employees safe and comfortable. Bringing employees back to work will be complex. For a start, businesses have had to implement a large number of new safety measures in response to COVID-19. However, ensuring safety in the workplace goes beyond adhering to social distancing measures and anti-bacterial cleaning stations. Behind the scenes, heating, ventilation and air conditioning (HVAC) play a crucial role in facilitating a safe workspace. Whether it’s the systems implemented to limit the spread of the virus, the ongoing servicing of these systems or their wider environmental impact, HVAC solutions and facilities managers (FMs) rest at the heart of a safer return to work. Embracing new strategies for clean air Walking in the building through a new automatic door, most office workers will be greeted with a queue for the lifts and plenty of signage reminding you to sanitise your hands and keep your distance. Some may have their body temperature scanned by a thermal detection camera on entry, which could also count how many people enter to ensure numbers are safe. Others could be met with an anti-virus access point that scans your face using facial recognition rather than a pass, and enforces hand hygiene by dispensing sanitiser before the lifts will open. Behind the scenes, heating, ventilation and air conditioning (HVAC) play a crucial role in facilitating a safe workspace All of these measures, however strict, are part of the new normal: ‘contactless’ buildings. Designed to limit the potential spread of COVID-19, facilities managers have plenty of options when it comes to keeping people safe. But not all of them are so apparent when entering a building. Some of the most important measures are those we can’t see. A healthy and safe working environment has always relied on a building’s HVAC infrastructure – temperature control, good air flow, and a reliable level of comfort are top of most office workers’ priority lists. But the pandemic has taken this to a new level of importance. As a critical part of their wider health and safety plan, facilities managers can look to identify strategies to increase clean air levels further. This could include increasing outdoor air circulation to decrease pathogen exposure, with smart air handling units. These will enable managers to bring in more outside air to displace potentially contaminated air, by increasing ventilation and air change rates. Improving Filtration Methods Improving filtration methods is another possibility, by adding additional filters including high efficiency filters and HEPA filters, to trap more particles and increase the percentage of clean air in a building. Portable HEPA solutions are also an option for those who need more flexibility. In addition to air filtration and circulation, it is also possible to use UV-C lighting to effectively ‘disinfect’ the air or surfaces, using ultraviolet germicidal irradiation (UVGI) to inactivate viral microorganisms. These can be installed brand new or retrofitted into existing facilities, to reduce costs for FMs and speed up implementation. These innovative uses of HVAC to limit the spread of infection could have a huge impact on the health and safety of occupants in any building – and this is by no means limited to offices. Within healthcare and laboratory facilities, for example, solutions like room pressurisation, air change rates, humidity and temperature controls are all critical to reduce contamination in the air and on surfaces. A healthy and safe working environment has always relied on a building’s HVAC infrastructure Safety is an ongoing process No matter which HVAC solutions a facilities manager chooses, it’s not a case of installing them and then waving goodbye. As with any good health and safety strategy, constant monitoring is crucial to ensure building occupants are well looked-after – and this also ensures you can get the most out of HVAC investments. For some this means keeping a close eye on how your HVAC equipment runs, to ensure that they’re reaching optimum performance and delivering the best ROI. Working with a partner who can provide continuous service and monitoring is critical, so that the pressure is off FMs themselves. Especially now, having remote monitoring capabilities is an added bonus, so that minor issues can be fixed without an engineer having to visit the site. For those with smart technologies in place, such as smart connected chillers, FMs may rather be reliant on predictive maintenance and monitoring tools, which use AI and automation to predict issues before they arise, and ensure equipment runs reliably and downtime can be minimised. Whether in person or remotely, good quality service and maintenance of HVAC equipment goes a long way – both to get the best return on investment, and to keep buildings as safe and comfortable as possible. Enabling a smarter and more sustainable workplace HVAC has always been critical to keeping employees happy and healthy at work – but for a long time this has had a negative impact on the planet. Inefficient HVAC systems can give a building a much bigger carbon footprint than it would ideally have. 75% of organizations plan to increase their investment in energy efficiency and smart building technologies Last year, our Energy Efficiency Indicator survey found that 75% of organizations plan to increase their investment in energy efficiency and smart building technologies. The opportunity, then, to overhaul HVAC systems in order to limit the spread of COVID-19 is also an opportunity to invest in more efficient, greener HVAC technologies, built for the future. Taking a holistic approach to your HVAC equipment is the best way to do this, to ensure efficiency gains can be made across an entire building or estate, by connecting intelligent systems. Chillers, for example, with efficiency and intelligence built in as standard can reduce energy use and carbon emissions for a building, or collection of buildings, helping FMs meet energy targets and keeping costs low. Choosing the optimal HVAC system Under current circumstances, the decisions made by FMs are pivotal in enabling business continuity and will ultimately impact building occupants’ comfort and safety. It should therefore come as no surprise that businesses are paying close attention to every move FMs make. Choosing the optimal HVAC system for your building and ensuring regular servicing and maintenance will prove cost-effective and energy efficient. Not only this, but smart HVAC technologies go a long way in enabling a safer, productive and more sustainable working environment. By picking the right tools for the job, businesses of every type can position themselves for growth while remaining as safe and secure as possible.
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.
It is common knowledge that a geothermal heating and cooling system provides a school with one of the most energy efficient climate control options available. What tends to be overlooked is that there are several geothermal system options available, which offer varying degrees of cost savings. Bard offers a type of geothermal system that provides the climate control and ventilation that a classroom deserves and maximizes cost savings. This was the challenge recently posed to Bill Stalker, a Marketing Manager for the Tennessee Valley Authority. To assist his efforts, Mr. Stalker called on Blake Neville, P.E., of Neville Engineering to perform an independent study of two different geothermal systems. Bard system chosen for the study The Bard system chosen for the study featured a 4-ton packaged QW series ground source heat pump The Bard system chosen for the study featured a 4-ton packaged QW series ground source heat pump with its patented, built-in energy recovery ventilator. The other system consisted of a 3-ton console heat pump and a separate, dedicated ventilation air unit (both provided by two widely-used, well-known HVAC manufacturers.) General assumptions like the number of occupants, ventilation loads, cooling/heating hours, installation costs and well drilling expenses were identical for both systems. Increases Savings Per Classroom Based on the study’s numbers, the Bard unit would not only save a school district $1,300 per classroom in upfront installation costs, it would continue to save them $493 per classroom every year in operating costs. Multiply both the upfront and operating savings by the number of classrooms in one’s school, and it all adds up to additional budget money for a few more field trips, a few more library books, a few more teaching supplies, etc.
Nicknamed the gateway to Southern California, the city of Ontario, as well as neighboring city Montclair, is home to the third largest elementary school district in California, the Ontario-Montclair School District (OMSD). Founded in 1884, the district also incorporates portions of the city of Upland, and unincorporated areas of San Bernardino County, comprising 24,000 students in 26 elementary schools and six middle schools. Ontario-Montclair School District Ontario-Montclair School District’s overall mission is simple yet speaks volumes to its dedication to all students, to do whatever it takes to guarantee its commitment in providing the highest quality education for all students. To meet this mission head-on, OMSD contracted with TMAD Taylor Gaines, a professional engineering consulting and services firm. Ontario Montclair School District was interested in reducing their overall energy costs by 20%" “Ontario Montclair School District was interested in reducing their overall energy costs by 20%, they along with other school districts throughout California were mandated to reduce their overall energy costs,” said John Simmons, RCDD, LEED AP, and Project Manager for TMAD Taylor Gaines. He adds, “We initially ran some numbers based upon information we found on Bard HVAC’s website, and through consultation with Geary Pacific Supply, Bard’s largest West Coast distributor.” Geary Pacific, distributor of new HVAC units Based upon the scope of the projects in consideration, the money available to fund them and the overall cost of the units in consideration, as well as overall potential energy savings, TMAD Taylor Gaines recommended that OMSD select Geary Pacific as the distributor of the new HVAC units. “We considered other companies as part of our overall recommendation but in all honesty we were impressed by a couple of things. First, Bard Manufacturing had a wealth of product and technical information about their products on their website, including case studies of other customer successes. That in combination with Geary Pacific’s previous experience working successfully with the School District made our recommendation a simple one,” added John Simmons. Bard wall-mounted HVAC units deployed “Our District was already familiar with Bard because we had success using some of their other wall mounted units on several of our modular school buildings,” said Craig Misso, Director of Facility Planning & Operation at Ontario Montclair School District, adding “Our goal was to not only upgrade our facilities and make them more energy efficient, but also work to reduce some of the HVAC noise inside the classroom, as well as save on the purchase, operation and maintenance of all of the units at our schools.” TMAD Taylor Gaines and Geary Pacific’s approach was to do the retrofit in several phases. The pilot project encompassed one site, Sultana Elementary School, which included 24 re-locatable buildings, made up of both newer and some older construction. Bard WG*S Step Capacity Series units with CO2 sensors TMAD Taylor Gaines and Geary Pacific started doing groups of schools, encompassing 14 different building sites “Sultana was a great school for the pilot because there were a lot of little issues to contend with and work through,” stated Simmons, adding “The Bard WG*S Step Capacity Series units with Energy Recovery Ventilators and CO2 sensors worked great and we were initially very surprised at how quiet they actually operated.” After that, TMAD Taylor Gaines and Geary Pacific started doing groups of schools, encompassing 14 different building sites. Group one included 6 schools and approximately 83 units while Group 2 included 8 schools and 101 units. It was during the second group of installations that TMAD Taylor Gaines realized that putting in units that required the installation of underground gas piping was not the best solution for all classrooms. Bard’s Quiet Climate 2 units That’s when Geary Pacific recommended utilizing Bard’s Quiet Climate 2 units with Energy Recovery Ventilators and CO2 sensors in about 1/3 of the overall installation. “Bard’s Quiet Climate 2 units are some of the most energy-efficient HVAC units on the market today,” said Maury Tiernan of Geary Pacific, adding “Plus the operational sound level is extremely low and is greatly appreciated by the students and teachers.” John Simmons said, “We were really pleased at how easily these units were able to be retrofitted into the re-locatable classrooms. There are almost no changes and smooth sailing in almost all cases.” Quiet, efficient operation The dramatic reduction in operating noise levels was an added improvement and benefit for which Craig Misso was particularly proud. “At Sultana, we invited some of the teachers and our principal over to see the new classrooms. Our principal asked, ‘Why aren’t the new HVAC units running’? I had to laugh, because I knew they were on. They were just so quiet nobody could tell that they were working. That moment sold every teacher on the Bard units,” added Craig Misso of Ontario Montclair School District. “From the very beginning, Geary Pacific became our partner in the success of the project,” stated Simmons, adding “Always available to answer questions on-site and knowledgeable about all aspects of the product and installation I can honestly say they can’t do anything wrong by me. Geary Pacific and the engineers at Bard Manufacturing came through in every way possible and more.” Wall-mounted heating and cooling equipment expert Bard’s HVAC products offer a combination of quiet operation, and energy efficiency Over thirty years ago, Bard Manufacturing began solving the comfort needs of schools across the country by providing wall-mounted heating and cooling equipment. Bard’s HVAC products offer a combination of quiet operation, and energy efficiency, with unsurpassed quality and dependability that make them the #1 choice for schools. With three, state-of-the-art manufacturing facilities and a global distribution network, Bard’s commitment to quality and product innovation begins with its commitment to research and development. With features like self-diagnostics and self-programming energy monitors, Bard delivers products that provide tangible solutions for any school. Energy and cost savings “The Bard units reduced ambient classroom noise levels by over 75% and further gave us a 50% savings in energy,” said Misso, adding “This savings allowed us to also install software on our computers that automatically turns off the lights and the AC, when the classrooms are unoccupied, which further increased our savings. Our hope is to have the funds necessary to install all 280 Bard units as specified by TMAD Taylor Gaines.” Misso concluded, “Geary Pacific has been extremely professional and service oriented throughout the project. Because of our School Board’s commitment to energy conservation, our District will receive a dual reward, recognized energy savings and efficiency with an enhanced classroom environment for our students and teachers. We couldn’t ask for anything more.”
