The Benefits of Zone Pressure Diagnostics
Weatherization and home performance contractors have been using zone pressure diagnostic (ZPD) testing since the 1990s to better diagnose, and ultimately improve, the airtightness of homes. Though our understanding of ZPD testing has come a ...
Manufacturers of radiant barrier materials claim that their products significantly cut cooling costs by reducing summertime radiant heat gain through attics and ceilings (see "Conservation Clips: Radiant Barriers Test Well," p. 45). A new study confirms that radiant barriers can indeed conserve cooling energy. [continue reading]
Residential energy auditors commonly find problems caused by dust and other airborne particles in forced-air heating and cooling systems. [continue reading]
It's cooling season, and if statistics are any indication, utilities, energy technicians, and HVAC contractors will be spending more time than usual dealing with mobile homes this summer. [continue reading]
An innovative way to cool houses has recently been tried at two sites in California. It's called night evaporative underfloor cooling storage (NEUCS). [continue reading]
Energy auditors cringe when they see open windows cooling off overheated apartments on cold days. By preventing apartment overheating, thermostatic radiator valves (TRVs) can cost-effectively reduce space heating energy use, according to a recent study in New York City. [continue reading]
Evaporative coolers cost only one-tenth to one-fourth as much to operate as refrigeration air conditioning and are much cheaper to buy ($400-$800). This makes them an excellent option, particularly in hot, dry areas of the country. [continue reading]
