Resolving the Circulation Dilemma in Multifamily Buildings
Demand-controlled pumping for hot water distribution holds high value in multifamily buildings.
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.

In 1995, a group of agencies in Florida teamed up to bring low-cost solar systems to low-income households so they could save money on their utility bills. [continue reading]
Reducing hot water costs is the most cost-effective way to save money for low-income housing in warm climates. This is one conclusion that can be drawn from a new study on the cost-effectiveness of energy-saving measures for low-income housing in warm climates. [continue reading]
The National Plumbing Standards passed by Congress in 1992 as part of the Energy Policy Act marked a turning point for U.S. manufacturers of toilets, faucets, and showerheads. [continue reading]
Many plumbing and heating designers have considered the tankless coil heating system to be the least efficient method of heating domestic hot water (DHW) in a multifamily building. [continue reading]
