Parts of the House That Stay On
We've come a long way in making hot water more efficiently. The next place to cut waste is in the distribution systems. [continue reading]
A wide range of options exist for ready-to-install, readily certified solar water heating systems. To further heat things up, government and utility incentives are expanding. [continue reading]
Q: It seems like I waste a lot of water while waiting for the hot water to get to my faucet. I have heard that tankless water heaters can ... [continue reading]
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.

Today, the Home Performance Coalition (HPC) calls on policymakers, industry leaders, energy program managers and contractors to redefine home energy ...
Zero-energy (ZE) homes—efficient homes that produce or procure as much renewable energy as they consume over the course ...
