Waste Not, Pay Not: Energy Recovery Ventilation
March 21, 2012
Proper ventilation is essential for maintaining good indoor air quality, yet it places an additional burden on heating and cooling equipment, which must condition air that will soon be exhausted from the building. Fortunately, energy recovery ventilation systems can help ameliorate this problem.

Hybrid Ground-Source Heat Pumps
March 20, 2012
Ground-source heat pumps are often prohibitively expensive because they're sized to meet the peak heating or cooling loads for commercial buildings. This video Tech Brief explains how hybrid models downsize the ground heat exchanger and use small supplemental cooling towers or boilers to meet peak load. ...
