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.

A recent analysis indicates that in cooling-dominated climates, relocating ducts to conditioned spaces can be one of the most effective efficiency measures for residential new construction, whether you’re focused on economics or the overall level of energy savings.

Have you always thought that short-cycling was an unavoidable yet insignificant aspect of boiler operations? Initial results from a new boiler control system indicates that not only is short-cycling avoidable, its near elimination can result in annual fuel savings from 20 to nearly 50 percent.
