Resolving the Circulation Dilemma in Multifamily Buildings
Demand-controlled pumping for hot water distribution holds high value in multifamily buildings.
In July 1993, Wisconsin Public Service (WPS) and Public Energy Systems (PES) began to evaluate the condition of existing Solar Domestic Hot Water (SDHW) systems as a precursor to a New Install Demand-Side Management (DSM) program. [continue reading]
Water heating--which accounts for about 16% of U.S. residential energy consumption--is one of the most complex end uses to evaluate, both individually and nationally. [continue reading]
In just four months last year, Pacific Power, with the help of Energy Technology Laboratories (ETL)--not to be confused with ETL Testing Laboratories--placed energy-efficient showerheads in more than 100,000 Oregon homes. [continue reading]
It is a documented fact that low-flow showerheads generally save less energy than a simple change in flow calculation would indicate. [continue reading]
How much energy do low-flow showerheads actually save? To answer this question, Proctor Engineering Group (PEG) and Pacific Gas and Electric Company (PG&E) metered 243 showerheads as part of a larger evaluation of PG&E's low-flow showerhead rebate program. [continue reading]
The Michigan Public Service Commission (MPSC) staff was interested in conducting a pilot program to look at the feasibility, cost and energy savings of electric-to-gas water heater conversions. [continue reading]
The Bonneville Power Administration (Bonneville) provides wholesale electric power to more than 100 retail distribution utilities in the Pacific Northwest. [continue reading]
