Efficiency

Con Edison has invested $1.3 billion in its electric delivery systems to keep service reliable this summer while continuing to be a brand that adds new technologies to build a clean energy future. Con Edison is preparing for a typically hot New York summer and one that brings the additional challenge of protecting the public and employees during the coronavirus health emergency. The company projects summer bills for typical New York City residential customers will be higher this summer due to more people staying home, as well as increased supply charges by power generators. In Westchester County, supply charges may result in slightly lower bills for typical residential customers, depending on usage. conserve on energy Con Edison does not make a profit on these supply charges and has taken steps to defer some of those costs, as customers struggle financially through the pandemic. Con Edison is working with customers on payment plans, has suspended turnoffs for non-payment and is waiving new late fees. The company advises that the best way for customers to manage their bills is to conserve on energy. The company advises that the best way for customers to manage their bills is to conserve on energy Con Edison has a variety of energy efficiency programs for residential and commercial customers and offers energy-saving tips. Conservation can be particularly important for residential customers who are spending more time in their homes during the pandemic. A typical New York City residential customer using 350 kilowatt hours per month can expect a 9.5 percent increase from $99.14 in 2019 to $108.53 per month in the June-to-September period. integration of clean technologies A typical Westchester residential customer using 500 kilowatt hours per month can expect an average decrease of 3 percent from $121.32 in 2019 to $117.63 per month. A New York City business customer using 10,800 kilowatt hours with a peak demand of 31 kilowatts can expect average monthly summer bills to increase from $2,203.94 in 2019 to $2,320.15 this year. “Safe, reliable power is essential for New Yorkers, particularly during the health crisis,” said Tim Cawley, the President of Con Edison. "We continue to invest to keep our system reliable and are accelerating the integration of clean technologies onto the grid. We also realize that these are difficult times for our customers and have taken steps to ease the financial burden and help them stay safe. Defeating the coronavirus requires a collective effort and the women and men of Con Edison are keenly focused on doing our part.” Investments in Reliability The upgrades cover all regions of the company’s 604-square-mile New York City and Westchester County service area While the company has put some work on hold, crews continue with work that ensures summer reliability, emergency work, and other essential projects. Company crews have installed new cable and transformers on the underground and overhead delivery systems. The upgrades also include network protectors and work at substations. The upgrades cover all regions of the company’s 604-square-mile New York City and Westchester County service area. In southeast Brooklyn, the crews have replaced 101 sections of underground cable and installed six new switches that isolate faults, reduce outages and allow for faster restoration of customers. In Westchester County, the company has continued with its $100 million storm fortification program, installing new poles, cable and switches to toughen the overhead system against storms. Storms often follow heat waves when warm, moist air fills the atmosphere. Impact of Health Emergency A project to enhance service in the northeast area of Staten Island replaced 170 spans of overhead conductor, 110 poles and 20 transformers. The project also includes the addition of four smart switches to the grid. Con Edison is also applying its engineering expertise to take stress off certain equipment in the southwest area of the Bronx, where the demand for power has grown. The company is transferring 6.6 megawatts of customer demand from one set of underground cables to another set that has capacity to accommodate the load. The project involves installing new cable and 2,000 feet of conduit. Con Edison’s initial projection for peak demand for electricity this summer was 13,220 megawatts under design weather conditions. But if major restrictions on opening businesses remain in place, demand could peak at 12,000 megawatts under design conditions. practice social distancing The record is 13,322 megawatts, which occurred at 5 p.m. on July 19, 2013. The company expects that more people staying at home due to the pandemic will result in less demand for power in highly commercial areas, such as Midtown Manhattan. But demand in residential areas will increase, particularly on weekdays, as people who are home during the day use their air conditioners and other appliances. Con Edison will take temporary steps if extreme heat and high energy usage place stress on the grid Con Edison will take temporary steps if extreme heat and high energy usage place stress on the grid. Those steps would include sending mobile generators to areas in need. Con Edison crews working in the streets practice social distancing with each other and the public and use face coverings when the requirements of the work make social distancing not possible. They follow the guidelines of the U.S. Centers for Disease Control and Prevention. Emerging Battery Technology  Battery technology has improved rapidly in recent years, providing Con Edison with another tool to help keep service reliable when the demand for power soars on hot summer days. Con Edison and its partner GI Energy have placed a battery system at a customer property on the North Shore of Staten Island. Under an agreement, Con Edison can discharge power into the grid at times of high demand. The system can provide 1 megawatt – or 1 million watts, making it a 1-megwatt/1 megawatt-hour system. Con Edison has a 2-megawatt/10.6-megawatt-hour battery system on company property in Ozone Park, Queens. The system, which the company debuted last year, discharges power into the local grid at times of high demand, taking stress off the electric delivery equipment upstream of the system. distributed energy resources Con Edison also encourages customers to consider whether solar energy is right for them Con Edison partnered with Enel X to install a 4-megawatt/16-megawatt-hour battery system – the largest in New York City - at the Gateway Center shopping center in Brooklyn’s East New York neighborhood. Con Edison also encourages customers to consider whether solar energy is right for them. Customers have completed nearly 32,000 solar projects that produce 290 megawatts of clean, renewable power. That is equal to 381,800 megawatt hours a year, enough to prevent 270,000 tons of carbon emissions, or the equivalent of more than 58,000 cars off the road. Counting combined heat and power, fuel cells and batteries, Con Edison customers provide more than 500 megawatts of power via distributed energy resources. Energy Efficiency Upgrades Customers can save money by using less energy. Con Edison offers customers incentives to make money-saving upgrades to their homes and businesses. For summer, Con Edison is offering residential customers: A $50 discount for buying a smart thermostat at Con Edison Marketplace and another $85 for registering it with Con Edison’s Bring Your Own Thermostat (BYOT) Program. Rebates on heat pumps (mini-splits and geothermal systems) that can also cool the user’s home. Con Edison is offering incentives for commercial and industrial customers. They include: Rebates on Energy Star and DesignLights Consortium-qualified lamps. The customers may speak to the lighting distributor for details. Savings for upgrading to more efficient LED lighting. Get up to $300 per LED fixture. Customers can visit the website for more information on available incentives. Small and medium-size businesses can get a free, no-obligation energy assessment of their facility. Con Edison will pay up to 70 percent of the cost for qualified lighting, HVAC, refrigeration and gas system upgrades. energy efficiency programs Since 2009, Con Edison’s energy efficiency programs have helped more than 1 million customers make upgrades preventing 6.8 million tons of carbon emissions. That’s the equivalent of more than 1.4 million cars taken off the road for one year. Con Edison is a subsidiary of Consolidated Edison, Inc., one of the US’ largest investor-owned energy companies, with approximately $13 billion in annual revenues and $59 billion in assets. The utility delivers electricity, natural gas and steam to 3.4 million customers in New York City and Westchester County, N.Y. For financial, operations and customer service information the official website of the company can be visited.

Camfil Air Pollution Control (APC), a global manufacturer of dust, mist and fume collection equipment, has doubled the size of its testing laboratory to include a climate-controlled facility with a new full-size dust collection test rig. The new equipment is dedicated to testing in accordance with ANSI/ASHRAE Standard 199-2016, Method of Testing the Performance of Industrial Pulse Cleaned Dust Collectors. ANSI/ASHRAE Standard 199-2016 testing Unlike other air filter standards that focus on HVAC systems, the Standard 199-2016 test process analyzes how well filters actually clean and how dust collectors perform as a whole. It is the first standard to provide a methodology for comparing performance results based on true operating conditions. Using a cartridge dust collector with four high efficiency filters, the unit feeds dust into the collector under specified conditions, measuring pressure drop and downstream emissions. Internal product quality testing Camfil will use the test rig for both internal product quality testing and to help customers simulate real-world conditions to evaluate the compliance and effectiveness of various filters. “We’ve always known that filters and dust collectors varied widely in performance, but now there’s a methodology to quantify that difference with actual performance data,” said Graeme Bell, Vice President of Camfil APC Americas. New testing capabilities Camfil APC was proud to serve on the Standard 199​​ project committee since its inception to help develop the standard" Graeme adds, “Camfil APC was proud to serve on the Standard 199​​ project committee since its inception to help develop the standard, and now we have a testing lab that makes it easy for dust collection equipment operators to perform the testing.” Camfil’s lab expansion also provides new testing capabilities. New equipment is available for research and development, customer support and testing for regulatory compliance. Highly sensitive scanning electron microscope A new, highly sensitive scanning electron microscope is equipped with the high level of magnification and resolution required to analyze high efficiency filtration media with nano fiber and PTFE membrane coatings. This microscope is one of the most sophisticated equipment available and will be used both for quality control of existing filter media and analysis of new media with potential performance improvements. Bench testing of dust collection samples The lab also houses an array of equipment used for bench testing of customer dust samples to take the guesswork out of dust collection, including a video microscope, particle size analyzer, moisture analysis and abrasion testing devices.

Viessmann has designed and developed a new modular, airtight intensive care unit (ICU), which could make a fundamental contribution to the care of seriously ill COVID-19 patients. The mobile, climate-controlled ICU builds on expertise within Viessmann’s Refrigeration Solutions division, which manufactures cold rooms with superior hygiene properties for a range of commercial applications. Thanks to their prefabricated and modular design, the one or two-patient portable ICUs can be transported in a 40ft container and set up in under three days. They can be used both indoors, for example in exhibition halls or sports arenas, and outdoors, under appropriate cover. Patient treatment from all four sides Suitable for use in temperatures of 2-40°C but it can be adjusted to operate in any conditions The units consist of an outer chamber and airtight inner chamber, each made of 100 mm polyurethane (PU) cleanroom panels, which are SmartProtec® antimicrobial powder coated and insulated to prevent energy loss. The outer shell of the unit is 3.2m x 3m x 7.2m (w/h/l), while the patient’s chamber is 2.6m x 2.5m x 4.2m. These dimensions are designed to allow the treatment team to reach the patient from all four sides. To avoid pressure drop and cross contamination, the entrance door to the patient's room is interlocked, as per an approved layout from the German Cleanroom Institut. The isolation chamber has a negative pressure of -15 Pa, as is common for the control of airborne infection in the care of patients with very contagious diseases. This is managed by a pressure sensor, as well as active pressure control and display. For immunosuppressed patients, pressure can be adjusted between +15 to +30 Pa. Highest air quality above patient bed Each unit features a plenum integrated air-conditioning unit for temperature control and recirculation, with separate fans for air supply and exhaust air. The design is suitable for use in temperatures of 2-40°C but it can be adjusted to operate in any conditions. The velocity can be set according to the needs and comfort of the patient between 0.1-0.15 meters per second The recirculation of air flow is undertaken by two high efficiency particulate air (HEPA) H14 grade filter fan units, designed to achieve the highest levels of air quality, located above the patient’s bed. The velocity can be set according to the needs and comfort of the patient, between 0.1-0.15 meters per second (m/s). The estimated grade of air quality in the bed area meets the ISO 7 or EN ISO 14644 standard for Particulate Cleanliness Class in Cleanrooms and Clean Zones. The return air is also filtered to H14-level via wall-integrated filter packages. Medical equipment can fit on both sides Units are also fitted with a switchboard cabinet, preassembled cable set and dimmable lighting The unit’s medical supply column is equipped in accordance with the recommendation of the Deutsche Interdisziplinäre Vereinigung für Intensiv und Notfallmedizin (DIVI) and can be adapted to clients' needs. It has standard setting dioxygen (O2), compressed air and vacuum, power sockets, a data connection and a nurse call function. The medical equipment for diagnosis and treatment can be fixed onto the vertical stainless steel tubes on both sides of the column. Units are also fitted with a switchboard cabinet, preassembled cable set and dimmable lighting (1000 lux in the patient’s room), in accordance with the IEC 60364 and VDE 100 standards. Collaboration for fast-track production Viessmann is also manufacturing its own newly designed compact ventilators, high quality respiratory protective face masks and hand sanitizer at its Allendorf factory in Germany.

With the Charger Low NOx Lochivar expands their range of Low NOx atmospheric gas water heaters, with three large commercial water models. Their complete Low NOx range has been designed to provide the most practical, cost-effective solution for replacement of existing water heaters. Their Low NOx Charger range is the only series of atmospheric gas water heaters available in the UK market with an output up to 90kW. They also meet strict ErP legislative requirements for NOx emissions. Condensing water heaters These products are designed specifically for replacement water heater requirements, especially where it is impractical to replace with condensing water heaters. The existing commercial building stock includes many of these types of water heaters and thanks to multiple draught hood options, the new Low NOx range can be installed on many existing flue systems, and they can also replace water heaters of competitive brands. Charger Low NOx water heaters have comparable hot water recovery rates, storage capacities and similar dimensions to previous models, making replacement easy. They meet the strict ErP requirements for NOx emissions introduced in September 2018 and are well below the permitted level of 56mg/kWh. A choice of draught diverter options provide further flexibility, and this range of water heaters can be used to replace any competitive brand.

As countries around the world work to contain the spread of COVID-19 and prepare to reopen, Trane Technologies is addressing critical needs for healthier air quality in buildings, hospitals and homes and safe transport for food and medicine. The global climate innovator has seen a growing focus on indoor air quality in buildings, including hospitals and other healthcare settings. At the same time, strain on the grocery supply chain and concerns about a pandemic-driven food supply crisis highlight the vital role transport refrigeration plays in getting perishables safely to their destinations. Healthier and Sustainable Buildings “Sustainable, reliable and efficient climate control technologies matter more today than at any other time in recent history,” said Mike Lamach, Chairman and Chief Executive Officer for Trane Technologies. “Society will increasingly depend on the latest technologies for airflow and filtration, controls and remote operation, and precision temperature control for transportation. As we serve these needs, strengthen infrastructure and increase efficiency and resiliency, we are improving health and safety for people, communities and the planet.” efficient built environments Technologies such as Trane Catalytic Air Cleaning systems include special filtration and UV light systems “While there are still a lot of unknowns about how the virus that causes COVID-19 spreads, what we do know is that proper design, installation and maintenance of HVAC systems are key to maintaining healthier and more efficient built environments,” said Dave Regnery, President and Chief Operating Officer for Trane Technologies. “By ensuring proper air treatment, filtration, ventilation and decontamination, we’re helping to keep people safe and comfortable in even the most challenging situations.” Technologies such as Trane Catalytic Air Cleaning systems include special filtration and UV light systems to remove pathogens and particulates from the air in healthcare facilities. In areas with specialized needs, such as isolation rooms and operating theaters, proper pressurization and airflow keep infections from spreading. supporting emergency hospital Other healthcare facilities, such as research laboratories and pharmaceutical manufacturers, also rely on specialized climate solutions to meet strict standards in air quality. Through rental options for climate and air quality control, Trane Technologies is also supporting emergency hospital expansions and temporary healthcare facilities – even tented facilities constructed in parking lots or parks. Remote monitoring and control systems enable building operators and technicians to monitor a building’s HVAC system around the clock, and technicians can diagnose and service issues that may impact efficient operation and air quality. Efficient Food and Medicine Transport It’s important that mechanical systems are checked and maintained after long periods of vacancy" “Beyond healthcare, indoor air quality is increasingly in focus as communities begin to reopen and people return to offices and eventually places like movie theaters, gyms, and shopping centers,” said Regnery. “It’s important that buildings’ mechanical systems are thoroughly checked and maintained after long periods of vacancy, with consideration to ventilation, airflow and humidity, to ensure healthy and efficient indoor environments.” Trane Technologies is helping to address another big challenge exacerbated by the pandemic: ensuring a safe, reliable cold chain to transport food and medicine. Feeding America says that food banks have seen a 70 percent increase in demand, and 40 percent of people served by food banks are new to the system. real-time intelligence “Perishable goods require precise temperature control,” said Regnery. “Even the slightest variance in temperature can cause food to spoil prematurely or compromise the integrity of life-saving medicine. Our communities need these products, so waste is not an option.” Thermo King telematics for real-time intelligence on the status of refrigeration equipment help fleet managers make sure units are running properly and efficiently to maintain safety and quality of the shipment. Further, the company offers special air filtration systems to improve air quality in vehicle passenger cabins for public transportation, such as buses. transport refrigeration technologies Trane Technologies is sponsoring and partnering with Feeding America and local food banks Through its transport refrigeration technologies and employee volunteers, Trane Technologies is sponsoring and partnering with Feeding America and local food banks to address growing food supply shortages and to divert food waste from farms to people in need. This includes establishing pop-up food pantries to serve thousands of people facing hardship. “We have an opportunity – and an obligation – to take care of our people, serve our customers in innovative ways and put our technology to work in service for our communities. Innovating and responding quickly are key to building community and global resilience,” said Regnery. transmission and mitigation There is strong evidence from The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) and other sources that HVAC technologies can mitigate the risk of exposure to infectious aerosols in built environments; however, the transmission and mitigation of COVID-19 in buildings is yet to be fully tested and confirmed.

Businesses need to take a three-step approach to reoccupying their buildings after the pandemic. The first focus is on preparing the building itself – maintenance inspections and conducting any maintenance which was put on hold. The second focus should be on preparing and training the maintenance team so they’re ready for the new normal. And the third step is preparing the workforce in advance through clear communication about what to expect when they return to work and what the organization has done to make them safe. creating a safe workplace Although maintenance is one of the least visible of the building services, it plays an important role in creating a safe post-pandemic workplace. Some buildings will have been left completely empty during the lockdown, while others will have been occupied with a skeleton staff. In some instances, companies may even have used the unexpected vacant period to upgrade plant or carryout intrusive servicing  – which would be disruptive when the building is occupied. Others will have ramped down M&E services and only continued with statutory requirements. It’s therefore best to start afresh and conduct a thorough inspection of all plant and systems – what has and hasn’t been completed over the last few weeks – and make a plan accordingly. Under new social distancing guidelines in workplaces, it will be more challenging for engineers to carry out works Under new social distancing guidelines in workplaces, it will be more challenging for engineers to carry out works. Once a general over-arching COVID-19 risk assessment has been completed on the facility, the next step will be to review all existing risk assessments keeping in mind social distancing guidelines and how best to reduce virus transmission. Once this is completed and the team trained on the new ways of working, put together a plan to carry out any non-essential maintenance which may have been put on hold when the building was closed. Ideally the plan should be completed in the coming weeks before full occupation. Planned preventative Maintenance For the same reason, examine the planned preventative maintenance activities due in the next few months and, where possible, complete them in advance of occupation. This will reduce the need for engineers to be in an occupied building, which is safer for them and others.  And it will ensure that the plant is running at its optimal state, improving the environment for returning building users. It’s likely that people will return to work gradually rather than in one go. Find out which areas will be occupied first. Are certain floors still going to remain closed, or will people be spread around the building?  Plan maintenance work accordingly. General HVAC equipment, such as heating and cooling systems, may have been switched off Life safety systems such as emergency lighting, fire alarm systems, fire suppression and fire extinguishers all need to be serviced to make sure they are operating correctly.  Generators and UPSs will need to be tested if they are to cover essential power. Lifts will need to be serviced because although they will be carrying fewer people, they will be operating more frequently thanks to reduced lift capacity. General HVAC equipment, such as heating and cooling systems, may have been switched off or working at a reduced rate to accommodate a skeleton staff and will need to be checked. If gas supplies were isolated by a registered Gas Safe engineer, then that individual will need to be brought back to reverse that move and a certificate obtained to demonstrate compliance. Conducting a full review of the BMS will help engineers to understand what systems around the building might not be working correctly.    HVAC tests for empty buildings In buildings which have stood empty over the last few weeks, it’s best practice to have a Legionella assessment before they come back online. The toxic mix of good weather and stagnant pipes should not be ignored. If standard legionella tests haven’t taken place in a closed building, then pipes should be flushed and temperatures taken before occupation. There has been some talk about the best way to reduce virus transmission through air conditioning by increasing the amount of outside air brought into AC systems which obviously also reduces the amount which is recycled. However, it’s important for occupiers to understand that while it reduces the chance for the virus to spread, it also reduces the ability for the indoor air temperature to be controlled so they may see fluctuations in temperature. Over the past few years, we have seen a significant increase in remote monitoring technology. There are a range of tools on the market – from wired sensors, optical remote sensors or wireless sensors – that enable organizations to monitor vibration, temperature, acoustics and power of numerous assets remotely but in real time through their BMS alerting the engineers to any pending failure. Installing this type of technology now, in advance of reoccupation, will mean organisations will no longer have to send people out into occupied buildings risking further transmission. It will also improve the efficiency and prolong the life of key assets. Installing these tools now means that should a second lockdown become necessary, plant and systems can easily be monitored. Reviewing emergency procedures Emergency procedures will need to be reviewed in light of social distancing Emergency procedures will need to be reviewed in light of social distancing. In the event of a fire, for example, is social distancing less important than the more immediate threat of a fire? How will bomb threats and other invac issues be managed with social distancing in mind? Hi-rises typically use cascade evacuations to ensure people can safely get out of a building without crowding and this could be adjusted to suit social distancing. In many cases, it will be up to the organization to decide on the new strategy. Much has been made of the new touch-free workplace. In terms of maintenance activities there are two options: keep doors open all the time and install a release mechanism for when a fire alarm activates or install automatic doors which are linked to movement sensors. The chosen option will depend on each organization’s particular business. Lastly, make sure the changes made are included in any return-to-work internal communications being disseminated to the workforce so they feel reassured that the organization is doing everything it can to keep them safe. Although maintenance processes and systems are not the most visible of a building’s assets, they play a crucial part in the safe reoccupation of the workplace and in maintaining an organization’s continuity in these troubled times.

Strategic electrification encompasses a host of solutions aimed at decarbonizing Earth’s atmosphere, decreasing pollution and reducing the costs of modern comfort and technology. Also known as “beneficial electrification”, this movement requires increased energy efficiency and end uses powered with electricity from cleaner grids and renewable sources. The movement will transform both the built environment and society’s modes of transportation. Despite the complexity of its challenges, strategic electrification can no longer be dismissed as a niche or a possibility of the far future. The movement is happening now, driven by a mix of public and private entities on various levels proceeding along voluntary and mandatory paths. What Is Being Done? In the absence of formal federal action on climate change — including the Clean Power Plan and Paris Accord — cities, states, municipalities and utilities are continuing to develop their own decarbonization strategies. There are now nearly 450 cities in the U.S. that have committed to 80% carbon reductions by 2050 The goal is to achieve this through a variety of policy mandates such as taxes, building codes and portfolio standards. This is in addition to voluntary approaches that can include utility rebates and construction decisions such as choosing a passive house design; updated building efficiency targets; system-specific electric mandates; and comprehensive gas bans. Just recently, Santa Cruz became the 30th city or county in California to enact a measure limiting or prohibiting the use of natural gas in new construction, according to an article published by Yale Environment 360.  The Carbon Neutral Cities Alliance Many organizations have rallied around these strategies. For instance, the Carbon Neutral Cities Alliance (CNCA) is one of the many organizations that have rallied around the strategies that must be employed to reach carbon neutrality. CNCA is a collaboration of leading global cities working to cut greenhouse gas emissions by 80-100% by 2050 or sooner. They’ve adopted some of the most aggressive GHG reduction targets undertaken anywhere by any city. Mitsubishi Electric Trane HVAC US was one of the organization’s first HVAC participants, providing expertise and product knowledge to support their continued efforts. Major CNCA cities include New York City, NY, San Francisco, CA and Washington, DC. If We Don’t Electrify, How Could That Impact the Environment? Cities are working aggressively to reduce fossil fuel use because our CO2 levels are trending in a dangerous direction. As a naturally-occurring greenhouse gas (GHG), CO2 helps earth retain enough warmth to sustain life but too much can lead to excessive warming. If our global energy demand grows and we continue to use fossil fuels in the same way, the average amount of atmospheric CO2 will likely exceed 900 ppm by the year 2100 For 800,000 years, before the Industrial Revolution and the widespread adoption of fossil fuel-burning technologies, the highest global average atmospheric amount of CO2 was 300 parts per million (ppm), according to the National Oceanic and Atmospheric Administration (NOAA). 407 ppm is the current average amount, per a trend report published by the Global Carbon Project. The NOAA also reports that if our global energy demand grows and we continue to use fossil fuels in the same way, the average amount of atmospheric CO2 will likely exceed 900 ppm by the year 2100. As atmospheric CO2 increases, the global temperature also increases, potentially reaching 1.5° C above pre-industrial levels between 2030 and 2052. At this temperature, the majority of climate scientists expect environmental changes to include rising sea levels, increased flooding, droughts, extreme heat, wildfires and new risks to human lives, infrastructure and biodiversity. According to the U.S. Energy Information Administration, buildings (residential and commercial) account for nearly 40% of the nation’s total energy demand — and about 75% of all electricity use. Where Does The HVAC Industry Fit In? Worldwide, all-electric heat pumps are the most popular technology for decarbonizing heating and cooling. VRF heat pumps and heat-recovery systems contribute to lower carbon footprints and benefit strategic electrification by reducing overall costs for commercial building owners, consumers and society. Instead of burning fossil fuels, a VRF heat pump provides heating to zones by introducing ambien heat its outdoor unit extracts from the air or a nearby water source. During cooling, VRF heat pumps reverse this process as indoor units transfer heat from zones to the outdoor unit which then rejects the heat. Until recently, some specifiers in northern regions felt obligated to select a gas-powered furnace or electric resistance for heating systems due to air-source heat pump derating at sub-freezing temperatures. Today that’s not the case. Mitsubishi Electric Trane HVAC US' SUZ universal outdoor unit uses Hyper-Heating INVERTER technology Air-source VRF systems now use advances such as flash-injection technology in the compressor to offer unprecedented levels of capacity and efficiency at low outdoor ambient temperatures. This creates opportunities to replace fossil-fuel-burning equipment in more regions than before. VRF heat pumps and heat-recovery systems help building owners, architects and engineers solve challenges associated with decarbonizing the electric grid as well as emerging building codes, standards and legislation related to decarbonization. Federal standards and programs like ENERGY STAR®, tax credits and utility rebates will continue accelerating adoption of energy-efficient alternates to fossil fuel burning systems. The Decarbonization Challenge The decarbonization challenge is significant and complex, but change is happening now. At Mitsubishi Electric Trane HVAC US, we’re passionate because we recognize the dangers of climate change and acknowledge the significant role we can play in decarbonization efforts. The decarbonization challenge is significant and complex, but change is happening now Legislation, codes, financial incentives, product innovations and environmental advocacy encourage the transition from fossil-fuel-burning equipment and will continue to evolve. We’re doing our part by researching, developing, manufacturing and providing training for the all-electric heat pumps and VRF systems that enable society to enjoy improved comfort while reducing both costs and carbon emissions. Ultimately, strategic electrification can only be successful if it’s associated with personal comfort and prosperous communities. 

A fuel called “Bioheat” is made by blending biodiesel made from organic and recycled products with ultra-low sulfur heating oil. The feedstocks used to make biodiesel include vegetable oils, animal fats, or recycled restaurant grease. About half the biodiesel produced in the United States is made from soybean oil. Blends are designated in percentages – a 5% blend of biodiesel with heating oil is B5, a 10% blend is B10, and a 20% blend is B20. Blends up to 5% are called “Bioheat,” while blends from 6-20% are “Bioheat Plus.” Blends from 21-100% are “Bioheat Super Plus,” and ongoing research is under way on higher percentage blends. The process of blending biodiesel into heating oil must meet ASTM D396 and 6751 specification and standards. Biodiesel-based Heating Oil Much of the home heating oil currently used in the United States contains biodiesel, but its use is not required in every state in New England, where the cold climate favors use of heating oil over electric heat pumps. The New York Heating Oil Association has pushed for mandates to use B20 blends by 2034, with the percentage of biodiesel increasing gradually from a B5 blend required in 2017. New York is the only state with an active mandate. Connecticut, Rhode Island, and Vermont require all neighboring states to have active mandates before laws go into effect. Although Massachusetts implemented a Bioheat mandate in 2010, it was subsequently replaced with a voluntary program because of costs. Lowering The Carbon Content The process of blending biodiesel into heating oil must meet ASTM D396 and 6751 specification and standards The home heating oil industry is concentrated in five Northeast states: New York, Massachusetts, Maine, Pennsylvania and Connecticut, which use 3 billion gallons of heating oil per year between November and March, according to the Energy Information Administration. The addition of biodiesel lowers the carbon content (and thus the environmental impact) of heating oil. The U.S. Environmental Protection Agency says biodiesel reduces greenhouse gas emissions, including nitrogen oxide. The process of making biodiesel from renewable and organic sources also boosts the environmental profile. Greenhouse gases emitted by the heating sector are significant. For example, in Rhode Island, the sector produces a third of the state’s 11 million metric tons of carbon dioxide equivalents released annually.  All Electric Systems And Heat Pumps Although biodiesel can help to meet carbon reduction goals, there is also a push for more expensive “all electric” systems (i.e., heat pumps) in cities throughout the Northeast. Pricing of heating oil blended with biodiesel is comparable with that of pure heating oil but may be somewhat higher. A blended fuel also burns cleaner and more efficiently, which reduces heating system maintenance and improves energy efficiency. Bioheat fuels can be used in the same tank and furnace system as standard petroleum heating oil without modification. Concerns Surrounding Biofuels The U.S. Environmental Protection Agency says biodiesel reduces greenhouse gas emissions, including nitrogen oxide There is some concern that producing biofuel stock could strain the food supply by displacing food crops in order to produce plant-based fuels on a large scale. Currently biodiesel is limited by the volume of available feedstock needed to achieve scale. Also, the lifecycle of producing renewable fuels may emit greenhouse gases. American GreenFuels, New Haven, Conn., has announced its biodiesel product has achieved environmental claim validations from Underwriters Laboratories. UL has confirmed that biodiesel produced by American GreenFuels contains an average of 42 percent post-consumer recycled content and 46 percent byproduct synergy feedstock content. As the largest biodiesel producer in the Northeast United States, American GreenFuels produces biodiesel from plant oils and recycled waste materials. 

Machine learning provides a tool to lower energy costs in a building, and Honeywell has launched a platform that incorporates the newer technology. Combining self-learning algorithms with building automation, Honeywell Forge Energy Optimization is a cloud-based system that analyzes a building’s energy consumption pattern and adjusts its settings. “We can help building portfolio owners fine-tune their energy expenditures to drive efficiencies and create more sustainable practices,” says David Trice, Vice President and General Manager, Honeywell Connected Buildings. Autonomous building solutions Honeywell says the autonomous, closed-loop building solution may deliver double-digit energy savings while decreasing a building’s carbon footprint. It can be implemented without significant capital expense or changes to a building’s current operational processes. The system autonomously and continually optimizes a building’s internal set points across hundreds of assets every 15 minutes by evaluating whether the HVAC system is running at peak efficiency.  When analyzing when to make an adjustment, the system considers factors such as time of day, weather, occupancy levels and other data points. The system considers factors such as time of day, weather, occupancy levels Honeywell Forge Energy Optimization calculates its decisions 96 times per 24-hour period in every building in a portfolio. Deployment is a simple plug-and-play process with no changes needed to business mechanics. Systems do not need to be rip-and-replaced. Results of the technology The technology has been demonstrated in a pilot at Hamdan Bin Mohammed Smart University in Dubai, United Arab Emirates, achieving an initial 10% energy savings. The pilot achieved the extra savings over and beyond what was achieved earlier in the highly smart, energy-efficient building with fully connected lighting, cooling, building management, power and efficiency control optimized based on real-time occupancy. The pilot also uncovered local control issues with the chiller plant and fresh air handling unit that were not adjusting to set points. “Honeywell Forge [was able] to drive further energy savings beyond our achievable optimization with the techniques we [had],” says Dr. Mansoor Al Awar, HBMSU’s Chancellor. The university is collaborating with Honeywell to support the advancement of artificial intelligence (AI) and machine learning to drive operational efficiencies. Energy consumption in commercial buildings is significant. Buildings and buildings construction combined are responsible for more than 36% of global final energy consumption and nearly 40% of total direct and indirect CO2 emissions, according to the International Energy Agency (IEA). Energy demand in these sectors continues to rise, driven by improved access to energy in developing countries, greater ownership and use of energy-consuming devices, and rapid growth in global buildings’ floor areas. Opportunities for energy saving It is a market where the potential impact of greater efficiencies is huge It is a market where the potential impact of greater efficiencies is huge. Heating, ventilation and air conditioning often presents the largest opportunity for energy savings in a commercial building. “Buildings aren’t static steel and concrete – they are dynamic ecosystems and their energy needs fluctuate based on ever-changing variables like weather and occupancy,” says Trice. “We are evolving building operations far beyond what would be possible even with a robust team of engineers and the rules they code in their building management system.”

Mobile systems are growing in popularity across the HVAC market, driven by convenience and changing demographics of the workforce. For younger employees, smart phones are almost an extension of their hands. As they enter the HVAC workforce, they are eager to embrace mobile systems. However, the simplicity of mobile systems is also attractive to older workers, who may be less inclined to use a complex desktop computer system. In the case of mobile systems, “limitation leads to creativity,” says Alex Meaney, senior Wrightsoft trainer at MiTek Holdings. Stripping down functionality to make a system available on a smart phone also makes it particularly easy to use. Utilising mobile systems HVAC professionals use WrightSoft’s software products, including mobile systems, to translate a site’s heating, cooling and ventilation needs into system designs and product choices to address those needs. Mobile systems do not complete the total design process, but they provide a start. Meaney says mobile systems are a “gateway to those who are less technically savvy.” Mobile systems are a “gateway to those who are less technically savvy” In addition to providing Right-J Mobile load calculation software for mobile platforms, WrightSoft also offers full HVAC design and build software for desktops. WrightSoft’s software can capture information from a CAD drawing or PDF and then calculate elements such as load, air flow, pressure drops, friction, etc. to ensure system performance, while taking into consideration elements such as moisture and outdoor temperature. The software creates a ductwork configuration and provides a materials list for the installer.  The flagship Right-Suite Universal product is sold modularly so customers only pay for what they need. The simplified interface does not require CAD expertise. In addition, the company’s latest Right-CAD product offers a more traditional CAD experience. Right-Mobile Consultant Another WrightSoft mobile system is the Right-Mobile Consultant, an in-home selling tool that can compare systems and operating costs, create a proposal, and includes tools for pricing. All the products are certified by the Air Conditioning Contractors of America (ACCA) and are based on ANSI standards. A feature of WrightSoft products is that they incorporate digitization of ACCA Manual J, which addresses load calculation. The software also incorporates expanded performance data, including proprietary engineering data provided by manufacturers, pre-loaded to enable users to recommend equipment based on ACCA Manual S, which directs residential equipment selection. The aggregated performance data provides value to WrightSoft’s OEM partners by allowing installers to automatically select equipment that complies with Manual S requirements by merely checking boxes in the software. The expanded data is more detailed and specific than Air-Conditioning, Heating, and Refrigeration Institute (AHRI) ratings, which are incorporated into some software systems but were never intended to be used by contractors to size equipment.  WrightSoft is part of MiTek Holdings, which also has HVAC-related subsidiaries M&M Manufacturing and Snappy, which provide metal ductwork. MiTek is owned by multinational conglomerate Berkshire Hathaway. Easing entry into the HVAC market Mobile systems can ease entry into the HVAC market of new, younger employees by providing instant access to expertise that older workers “keep in their heads” and had to learn over many years on the job. Helping to expand the labor pool is particularly timely as HVAC contractors have struggled to find enough employees. Cloud-based systems are also increasing productivity of HVAC installers Cloud-based systems are also increasing productivity of HVAC installers. Because information is now stored in the cloud, installers can enter information on a mobile product and then continue working on the same project on a desktop. WrightSoft’s focus is on residential installations, although some professional engineers also use the software for commercial projects. The company does not track how their software is being used in the market. WrightSoft typically interacts with customers at the point of sale, again when the software is updated, and also for support and training. Cloud technologies WrightSoft does not manage customer data or have access to a customer’s files. “Being in the cloud enables us to better tie all our technologies together and to tie into other industry partners in the building space,” says Micah Dawson, Product Portfolio Manager, HVAC at MiTek USA. MiTek overall is well positioned to expand their cloud-based services and develop a broader cloud offering over time, he adds. “There is a lot to know about HVAC design, and it requires a lot of input and analysis,” Dawson says. “People don’t realize they need software to help them.” HVAC systems are becoming more complex, which makes it harder for installers to rely on informal “rule of thumb” assumptions based on experience. “We as an industry have moved those assumptions, but some installers are not keeping up as things are becoming complex,” he adds. The incremental benefits achievable by using software can make the difference in a company’s success or failure, says Dawson, citing the turnover of companies entering (and sadly, exiting) the HVAC industry as a reflection of the need. There is a lot at stake for smaller companies especially, and there are around 60,000 HVAC contracting businesses with four or less employees. How software helps A wrong calculation or bad design choice could wipe away the profitability on a single job; or perhaps worse, hamstrung profitability over time could cause a smaller company to die “by a thousand paper cuts,” Dawson says. “Software allows you to get the design right at the digital stage, where it doesn’t cost anything, so you can be sure of the equipment you are spending so much money on,” says Dawson. Because of COVID-19, Meaney has shifted his training to online Because of COVID-19, Meaney has shifted his training to online, and the company is investing to improve that training. “We have enhanced and broadened our training availability significantly,” he says. Among the benefits of online training is the ability to spread out course material into shorter sessions spread over a longer period – several two-hour sessions rather than all crammed into two long days. In any case, Meaney expects online training to continue to play a larger role in the post-COVID-19 world. In general, the COVID-19 pandemic has increased the market focus on indoor air quality as we have all spent two months locked inside our houses. The benefit of using software to correctly design HVAC systems for the home will be more important than ever. Meaney predicts “the dam will break” after the quarantine ends as people look to improve their systems, not to mention catching up on routine maintenance.

With the rise of veganism showing no signs of slowing down, plant-based meal provider, allplants decided to consolidate its seven sites into a single, central facility. When the contracting company, Forma London was presented with the challenge of sustainably fitting out the new building, it turned to Elta Fans to deliver an efficient ventilation solution. Vegan diets are becoming increasingly popular for a variety of different reasons, including health, climate change, and animal welfare. As plant-based diets become mainstream, there is a growing need for convenient, meat-free meals, and offering greater choice for consumers. Sustainable building solutions allplants set out to meet this demand, making delicious frozen meals and delivering them straight to customers’ doors. Its success derives from the passion of its two founders, JP and Alex, and has necessitated the consolidation of its multiple sites into one central facility. The new premises provided allplants the opportunity to fit out the building with sustainability at its core Moving to new premises provided allplants with the opportunity to fit out the building with sustainability at its core. All the desks, for example, are made from locally sourced, sustainable wood, but it was in the kitchen that the greatest challenge was posed. Forma London, a principal contractor based in the capital, was tasked with delivering the project. Combining construction expertise with eco and ethical credentials, the contractors began working on providing ventilation for the meal provider’s centerpiece, the development kitchen. Enhanced ventilation The kitchen is where the magic happens, allowing allplants to ensure the meals it produces are as tasty as possible. As specialists in microwavable food, the traditional ventilation set-up of a commercial kitchen was far greater than what the site needed. Anthony Afram, Building Services Manager at Forma London, said “Balancing energy efficiency with performance output is a priority in any project, but given the nature of the client, this took on a whole new level of importance.” He adds, “The challenge of equipping the kitchen with the right ventilation was highlighted by the two bifurcated axial fans that we were originally quoted. These would have been perfect for a busy commercial kitchen, but for this application they were overkill. In terms of expense and performance, they would have been much more than required, and ultimately incurred far higher running costs than necessary.” Energy-efficient ventilation systems It isn’t just for the purposes of corporate social responsibility or an altruistic mindset that businesses must pay close attention to the energy credentials of their ventilation systems. Building Regulations and Ecodesign Directives obligate everyone in the supply chain, from manufacturer through to contractor, to select and supply ventilation with maximum levels of efficiency. This means that most commercial and industrial fans need to be provided with functionality that allows control over fan speed and power. Skyflow SSRL EC axial roof fans For allplant’s kitchen, this meant specifying a fan that was appropriate for a busy, but pollutant-low kitchen In the context of allplant’s kitchen, this meant specifying a fan that was appropriate for a busy, but pollutant-low kitchen. Owing to its position as the first ErP compliant low silhouette axial roof fan on the market, the decision was made to turn to Elta Fans’ Skyflow SSRL EC. Equipped with an EC motor with an integral potentiometer commissioning device as standard, the fan is ideal for environments such as a light commercial kitchen. Intuitive controls Anthony continues, “For applications such as this, where ventilation requirements may be variable, the ability to control fan speed through intuitive controls is vital. “It also highlights the importance of not over-specifying, as it can be all too easy to opt for the highest performance available, without consideration of the energy expenditure. “Elta Fans’ Skyflow SSRL is a great example of the energy saving possibilities associated with the latest ventilation technology. Opting for the most efficient products can make a significant contribution to the overall energy credentials of a building, and projects such as this illustrate what is possible.” Energy savings and sustainable HVAC system allplants is understandably concerned with sustainability, and the fitting out of its premises necessarily reflects this. However, it is important to be aware that its growth as a company shows the overall trend towards an environmentally-conscious society. As legislation is introduced to reflect this, those tasked with providing ventilation must ensure they opt for solutions that balance performance with optimum energy efficiency.

The task facing Donovan & Son’s, Inc., Plumbing/HVAC in Middletown, RI was to propose and install heating system boilers that allow the Preservation Society of Newport County to conserve on fuel costs, more closely match varying building heat loads, and coexist with the tremendously large water content of a gravity system. The historic mansions of Newport, RI are known for their elegance and remind its visitors of a bygone era of social and financial preeminence during the turn of the twentieth century in America. Cornelius Vanderbilt II, grandson of railroad industrialist Cornelius Vanderbilt (1794-1877) had the 70 room Italian renaissance inspired mansion built on the site of a wood-framed house which was destroyed by fire in 1892. gravity feed system The Breakers is now owned and operated by the Preservation Society of Newport County A year later, Architect Richard Morris Hunt, deployed an international team of craftsmen and artisans to create the mansion, which is considered to be the most elegant of the Newport summer cottages. The Breakers is now owned and operated by the Preservation Society of Newport County. The preservation society recently replaced an old inefficient boiler with two high efficiency model MPC9 boilers (up to 88.6% efficiency). The old boiler operated at minimal efficiency, especially during the spring and fall when the building demand only required partial load. The mansion, built during the dawn of electricity, used a gravity feed system with large 18-inch supply and return mains. This large supply and return mains divide up into a network of several smaller mains that feed scores of cast iron radiators hidden away in the walls of the structure. heat distribution system The radiation that heats The Breakers is built into the walls of the building and is for the most part out of sight. The heat distribution system consists of radiators lying horizontally in vertical structural chase ways throughout the building. Air connects upwards through these chase way-mounted radiators and is distributed into the rooms via ornately cut grilles in the marble walls allowing the system to exist without being seen. The task facing Donovan & Son’s, Inc., Plumbing/HVAC in Middletown, RI was to propose and install heating system boilers that allow the Preservation Society of Newport County to conserve on fuel costs, more closely match varying building heat loads, and coexist with the tremendously large water content of a gravity system. The boilers had to be installed as part of a century old high-mass gravity feed system. system injection piping MPC boilers have built-in return water temperature protection in the form of a return water mixing tube (RWMT) To do this, Donovan & Son’s converted the near boiler piping to a primary/secondary configuration consisting of a boiler room loop with boiler and system injection piping. The purpose of the boiler room loop was to create a buffer area where heated water from the boilers is no longer in direct contact with the cooler system return water as each boiler injects its heated water into the boiler room loop and in turn heated water from the boiler room loop is transferred into 18-inch supply and return mains, utilizing several small pumped connections. desired minimum temperature This configuration assists the flow of the gravity system to operate as it always has, by simply keeping the large system supply main hot and the boiler loop well above a desired minimum temperature. Such a large water volume in the system loop required that added consideration be given to boiler protection. MPC boilers have built-in return water temperature protection in the form of a return water mixing tube (RWMT). The RWMT protects the boiler from low return temperatures by distributing cool return water evenly throughout the length of the boiler, virtually eliminating concerns of thermal shock and providing balanced flow through each casting. Operating parameters for the MPC, with the RWMT, require a minimum 130ºF supply temperature, minimum 80ºF return temperature and a maximum of 80ºF ∆T. modulate supply water temperature Modular boiler systems provide redundancy if a mechanical device fails to operate during the winter months System operation is controlled by a Tekmar 264 boiler staging control allowing for two individual sets of high-low firing, or four stages of firing. The control also modulates supply water temperature based on outdoor air temperature fluctuations. Domestic hot water is generated using a Burnham Alliance indirect water heater which replaced a separate oil fired water heater. Staging the boilers, modulating the system set-point based on outdoor air temperature and installing the indirect water heater, all combined with the MPC’s high-efficient three-pass sectional design are key factors in reducing energy costs. A recent jobsite visit showed the outdoor temperature to be 38°F and the system water temperature at 155°F with one boiler sustaining the load on low fire. greatly reduced fuel costs The ultimate benefits of The Breakers’ new boiler system will be greatly reduced fuel costs and greater building comfort, by more closely matching the building heat load. Additionally, modular boiler systems provide redundancy if a mechanical device fails to operate during the winter months. The building can now be heated with as low as 25% of the total boiler capacity on the plentiful amount of moderate days that we encounter during the heating season. This will be a boiler system that will offer considerable payback for many years to come.

The new Adidas LDN flagship outlet in London, which opened late October 2019, has been specifically designed to enhance the retail experience. As the brand’s most technologically-advanced store worldwide, it required a ventilation system that would effectively deliver a fresh air supply across the four-storey, 27,000 sq. ft, site, in the most energy efficient way possible. Adidas is one of the most well-known sports brands in the world, and so it’s to be expected that when it launched its new store on Oxford Street, London, it would be no ordinary shopping experience. Digitally-Savvy innovations The store features over 100 digital touch points that are all powered by green energy The store features some of the most digitally-savvy innovations in retail, such as interactive mirrors in changing rooms that allow shoppers to order different sizes direct from the stockroom, a ‘Bring It To Me’ feature using in-store geolocation tracking to allow customers to shop without queueing, and a MakerLab where clothes can be customized with personalized designs. However, with additional energy usage comes additional heat sources, and therefore the size and volume of air required to keep the building and shoppers cool needed to be carefully calculated. The store features over 100 digital touch points that are all powered by green energy. While incorporating these interactive elements into the design of the store would, undoubtably, help to revolutionize the high street, subcontractor, PCB Technical Services, also recognized that they would increase energy usage and would therefore result in additional heat loads. Enhanced technical support With this in mind, a ventilation system that would be able to meet a consistently high demand at all times was required. What’s more, a quick turnaround was essential to ensure the unit would be installed and delivered within time and budget. After an initial supplier interview and factory review, Ricardo Hudson, Senior Technical Project Manager at PCB Technical Services, was given the confidence to opt for a bespoke Air Design unit from Elta Fans. This was thanks to the company’s enhanced technical support and understanding of the project, as well as its ability to meet the tight delivery date. Elta Fans uses in-house Air Design technical engineers who utilize specialist software to tailor the unit especially for the customer’s exact needs; considering performance, efficiency, noise, and, most importantly, the latest regulations and any site restrictions. Air Design ventilation unit The Air Design ventilation unit supplied by Elta Fans was custom-made, ensuring it was able to effectively ventilate Providing fresh air to a store as big as this one is essential if customers are to feel comfortable while browsing, but it is also crucial that adidas adheres to the most up-to-date energy standards and legislation. The Air Design ventilation unit supplied by Elta Fans was custom-made, ensuring it was able to effectively ventilate according to the unique size and layout (across four floors) of the store. The specialized solution chosen, the fully-configured PURA+ Air Handling Unit (AHU), would be mounted on the roof to maximize space on site. The challenge of transporting the AHU into position was exacerbated by the high-profile nature of the location. PCB Technical Services was reluctant to disturb the busy street, particularly given the strict local regulations that had to be upheld. Improved ease of installation A great deal of planning was required to fit the unit as PCB had to work within a limited timeframe, gain the relevant planning permission, and eliminate as many risks as possible to nearby occupants and shoppers. As a result, the team was required to arrange a specific timeslot for delivery to site. As the Air Design unit was manufactured offsite, it was able to be lifted into place by crane, minimizing road closure time, and ultimately disruption. This also improved ease of installation as it was delivered in two parts and could be easily bolted together once in place. Now installed and operational, the AHU delivers a consistent fresh air supply into the building by removing polluted air and replacing it with clean air, at the most efficient temperature.  Balancing indoor air quality This allows the store manager to balance indoor air quality (IAQ) and energy efficiency Building Management System (BMS) controls enable the store manager to ensure the ventilation system is working as it should in tandem with other products. This is essential as it is not just the store itself that needs to be kept cool, but also the data center, which generates a significant amount of heat from the servers. Controls will essentially determine how a ventilation unit runs, whether that’s scheduling airflow, linking to a BMS, permitting fault signals and alarms, or communicating that filters need changing. Ultimately, this allows the store manager to balance indoor air quality (IAQ) and energy efficiency, and also effectively manage operating costs. Evolving ventilation demand Ricardo said: “The unique challenges of the project were amplified with the introduction of a series of in-store digital screens. This meant that more heat was being generated within the structure, thus increasing the levels of ventilation required.” “It also necessitated wholesale changes to the ductwork system, in order to increase the velocity and retain ambient temperatures. Owing to its reputation in the industry and having already completed several successful projects together, Elta Fans was the standout choice to provide us with an AHU capable of meeting this evolving ventilation demand.” The bespoke PURA+ that we ultimately installed was ideal for meeting the velocity" “The bespoke PURA+ that we ultimately installed was ideal for meeting the velocity and air volume required for the store’s footprint. Plus, it was able to integrate with the BMS, enabling us to manage the significant amount of power throughout the building.” Quickly identify ventilation requirements Melissa Goodman, Technical Sales Manager at Elta Fans, said: “The challenge of providing consistent air flow across the site’s four floors was underpinned by the tight time constraints. It presented the Air Design engineers with an exciting opportunity to produce a bespoke PURA+ that was both straightforward to install, but also robust and powerful enough to perform as required.” Ricardo concluded: “Finding a bespoke solution in a short amount of time is difficult, and this project highlights the importance of choosing a brand that offers consistency, even in its customized products. The adidas project was a perfect example of Elta Fans’ ability to quickly identify ventilation requirements, and the PURA+ unit provided by Air Design highlights its precise approach to tackling air movement problems.”

Two new Burnham model MPC™ high efficiency commercial boilers were recently installed by The Witmer Company of New Holland, PA in the historic ‘High Point’ Mansion located in Hershey, PA. The Model MPC boilers will provide space heating for the 22-room Mansion which was built in 1908 as the home of Milton and Catherine Hershey. Mr. Hershey was the founder of the Hershey Chocolate Company, now known as The Hershey Company. Today, ‘High Point’ Mansion serves as the headquarters location for the Hershey Trust Company which, among other things, oversees the continued philanthropic efforts that were founded by Milton Hershey. Exceptional heat transfer Two, five-section model MPC boilers were selected to provide heat for the building through a combination of 5 air handlers, 52 fan coils and commercial finned tube radiation. The MPC’s are well suited for the job with their unique 3-pass flue design and Return Water Mixing Tube, which translates into exceptional heat transfer as well as the ability to accept return water temperatures as low as 80°F. The MPC’s 4-inch insulation blanket insulates the boilers so well that the jackets stay cool to the touch The MPC’s are manufactured in nearby Lancaster, PA using BC25-HSi cast iron sections, which contain high levels of silicon for exceptional flexibility and heat transfer capabilities. Even at start-up a big difference could be noticed – the boiler room temperature had dropped 30-degrees from the previous boilers. The MPC’s 4-inch insulation blanket insulates the boilers so well that the jackets stay cool to the touch, and the boiler room at the Hershey Mansion is now a much more comfortable place to work. Heat distribution systems Heat transfer and high efficiency is only part of the equation in this new installation, with a variety of heat distribution systems and controls the MPC’s needed to integrate with an advanced control system. The power burners were ordered with the powerful new Burnham SBC™ – or Sage Boiler Control, which made the control portion of this job simple for the Witmer crew. The SBC’s control many of the boiler room functions such as outdoor reset, multiple boiler modulation, lead-lag boiler rotation, combustion air louvers, and pump controls, all without the need for additional control systems. And the SBC’s tie right into the existing building management system so the whole system works together to deliver comfortable, efficient heat throughout the beautiful historic Hershey Mansion.
