Battle against climate change

Logical approaches to addressing climate change in the HVAC industry can provide both indoor and outdoor environmental improvement as well as financial benefits. Sample energy reductions calculated by the building owners present paybacks about one year while they reported superior indoor conditions for their building occupants.

DX Cooling Opportunity

HVAC systems that mix fresh air and building return air to varying quantities for cooling purposes often have control logic comparing the total heat content of the outdoor to the total heat content of the return air.

HVAC logic improvements

APS has developed many unique HVAC logic circuits: improving comfort and reducing energy consumption. The reductions caused the avoidance of over 60,000 person-years of GHG emissions with a three-person crew.

Old HVAC systems don’t listen — they just run. Smarter control means only heating or cooling where and when it’s needed. That’s how buildings are saving up to 57% on
Why is your building still hot and stuffy even after professional air balancing? A commercial building kept getting uncomfortable in the afternoons. Three different air balancing companies tried to fix
Controlling humidity isn't just about comfort—it also helps reduce the spread of viruses and bacteria. While most standard humidifiers use a lot of energy, cold-water spray systems can actually help
Enthalpy is the total heat content value in air, considering both dry bulb temperature and relative humidity level. If either value changes while the other is constant the enthalpy value
