Engineering models of the physical processes of energy use in individual houses are quite complex. We investigate simple statistical models of summer electricity use and compare them to engineering models. Our data include interviews, energy audits, and utility billings for a random sample of...

We describe the results of a study to estimate the energy intensities of major end-uses in commercial buildings in the PG&E service area. These energy intensities are central to commercial sector electricity and natural gas consumption forecasting models that utilize an end-use approach. The use...

The Department of Energy has proposed energy efficiency standards for eight types of appliances. One of the criteria used to establish these standards is the economic impact of the standard on the consumers of the regulated products. A life-cycle cost analysis was performed for 32 classes of...

During the summer of 1980, Davis (CA) undertook a program to encourage residents to reduce peak electricity use. The program was initiated by the local utility company and carried a collective financial incentive: for every 1% reduction in peak electricity use, the utility would reward the city...

Lighting has been one of the fastest growing electric end uses in China over the last 20 years, with an average annual growth rate of 14%. Fluorescent lighting provides a significant portion of China's lighting needs. In 1998, China produced 680 million fluorescent lamps, of which 420 million...

Benchmarking has been recognized to be an effective analysis methodology and management tool that helps to improve efficiency and performance in many areas for different objectives. Industrial energy benchmarking is a process of evaluating energy performance of an individual industrial plant or...
