Demand Controlled and Energy Saving Pumps
Two authors discuss how these water pumps save money by working only as hard as they need to
A boiler is generally more fuel efficient than a standard gas water heater, especially when the boiler is fully loaded. [continue reading]
Energy use for domestic hot water (DHW) is the second largest component of a multifamily building's energy budget; it is surpassed only by heating in cold and mixed climates. [continue reading]
Multifamily buildings with more than five units make up about 17% of all U.S. housing, yet scant information exists on the fuel use of these building in specific locations (see "Multifamily Statistics"). [continue reading]
Ground source heat pumps (sometimes called geothermal heat pumps, Geo-Exchange Systems, or GHPs) most often exchange heat with the ground by means of a ground heat exchanger. [continue reading]
Have you ever wanted to calculate how much energy a water heater would use annually in a given household? To make this task easier, Lawrence Berkeley National Laboratory (LBNL) has developed a straightforward equation that produces results close to those of simulation programs--without their baffling complexity.

Space conditioning is the biggest piece of the residential energy pie, and thermal shell improvement is a homeowner's best opportunity ...
Energy supplies and efficiency in new home construction took an interesting turn when researchers at Oak Ridge National Laboratory (ORNL) ...
