Resolving the Circulation Dilemma in Multifamily Buildings
Demand-controlled pumping for hot water distribution holds high value in multifamily buildings.
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]
The technology to increase energy savings and improve the performance of domestic hot water (DHW) heating systems has been around for years. The problem is that few people know what's out there and even fewer are getting to use it. [continue reading]
Over a third of America's domestic hot water is heated by electric resistance elements. For many residences, electric resistance is a more expensive method of water-heating than fossil fuels or solar, but there are buildings where these latter alternatives aren't feasible. [continue reading]
