Is your HVAC system burning money?
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.
Why is your building still hot and stuffy?
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 it… But nothing worked.
Breathe Easier, Save Energy:The Hidden Benefits of Cold-Water Humidification
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 save on heating costs.
Enthalpy Report
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.
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.
Bourdon Tube Investigation
Industry experts contacted indicated that the volume of a Bourdon tube does not change while flexing or they had no data on this consideration. If the industry consensus is true, work output can exceed work input (Wout ˃ Win) as per an APS experiment.
Significant savings for school
This HVAC case study examines the heating control systems in the oldest high school in Peterborough, Ontario, and proposes energy-efficient improvements.
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.
How efficient are HVAC systems in filtering virus
The APS manual highlights concerns about the effectiveness of HVAC system upgrades in mitigating COVID-19 transmission. While authorities have recommended increasing ventilation and upgrading filters to MERV 13, APS questions the necessity and efficacy of these measures.
