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 has to change.
This HVAC case study examines the heating control systems in the oldest high school in Peterborough, Ontario, and proposes energy-efficient improvements.
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.
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 energy bills.

Did you know that fossil fuels will be exhausted in your lifetime?
