Heat-Pump Water Heaters – the Next Frontier of Sustainability Heat-pump water heaters are the most viable carbon-free solution for domestic hot water, and can help make ambitious sustainability, electrification and decarbonization goals a reality. This article originally appeared in BuildingEnergy magazine, Fall 2019: Situation Overview: Why Heat-Pump Water Heaters? The commercial and residential building sector consists of many […]
Cut Energy Costs by 40% with Preventive HVAC Service and Maintenance
Cut Energy Costs by 40% with Preventive HVAC Service and Maintenance Save Money, Time and Resources Did you know that many HVAC systems contain over 100 components? That’s a lot of moving parts. And the minute any of them run into a problem, system performance, efficiency and effectiveness are impaired. The key is to conduct […]
5 Reasons Why Building Efficiency Matters
5 Reasons Why Building Efficiency Matters The built environment in the U.S. is extremely inefficient. Consider these facts: Buildings consume roughly 40% of the total energy used in the U.S. and more than 70% of the country’s electricity, according to the U.S. Department of Energy.[1] The U.S.’s building stock each year uses more energy than […]
4 Reasons Why Hospitals Need Photocatalytic Oxidation to Fight MRSA
4 Reasons Why Hospitals Need Photocatalytic Oxidation to Fight MRSA Rising Patient Infection Rates are a Major Challenge Hospitals are increasingly challenged by rising patient infection rates, especially from hospital-acquired infections / healthcare associated infections (HAIs), such as methicillin-resistant Staphylococcus aureus (MRSA). MRSA causes about 80,000 infections and 11,000 deaths annually in the U.S. (CDC), as well as up […]
Controlling Legionella In Cooling Towers And Condenser Water Systems
Controlling Legionella In Cooling Towers And Condenser Water Systems Legionella can be controlled in cooling towers and condenser water systems with four steps to reduce bacterial growth and improve the safety of building occupants. No building should make people sick; however, due to poor planning, the water in cooling towers and condenser water systems can […]
Heat-Pump Domestic Water Heaters
Heat-Pump Domestic Water Heaters Conventional Water-Heating Systems are Inefficient Heating water in New York City’s buildings can be expensive and harmful to the environment, especially if fossil-fuel-burning heaters or furnaces are used. In fact, older heaters can waste up to 20% of their fuel, and even newer models can waste up to 10%. This results […]

By Richard Gerbe CEO and Co-Founder The commercial and residential building sector consists of many structures that are inefficient with […]
Four Steps to Controlling Legionella Growth in Cooling Towers
Four Steps to Controlling Legionella Growth in Cooling Towers No building should be making people sick; however, because of poor maintenance and cleaning efforts, the water in cooling towers has the ability to serve as the breeding ground for a variety of bacteria. One such bacterium is Legionella, the root cause of the recent major […]
