California's electrical system peak demand is growing rapidly in the residential sector, mainly because of increased air conditioner use due to increased population growth in the central valley. This project...

California and other states with hot dry climates need air conditioners that maximize indoor temperature reductions for the expended energy. This is particularly true at high outdoor temperatures. This study...

Residential evaporative condensers offer effiency advantages over conventional air-cooled conditioners by utilizing evaporative cooling to improve condensing unit performance. The evaporative cooling process results in a 30-40F reduction in...

In-home display (IHD) devices provide homeowners with “real-time” data on total home energy consumption, giving them greater control over energy use and taking the surprise, delay, and mystery out of...

This project analyzes and tests the integration of night ventilation cooling technology into a standard heating, ventilation, and air conditioning (HVAC) system. Night ventilation systems automatically ventilate houses using the...

The BreezeAir single-stage advanced evaporative cooler is an Australian product that has recently been introduced into the U.S. market. This product differs from U.S. advanced technology in that it...

Air conditioning (AC) is the primary cause of peak electrical demand during California’s hot summers. This project evaluates air conditioners that perform better in hot dry conditions, resulting in reduced...

The first phase of an evaporative cooler technology evaluation project conducted 2003 tested the performance of advanced evaporative coolers (AECs) that used 8 inch thick rigid media. The results...

This project is a demonstration of the energy-efficient CFL downlight fixture developed by the California Energy Commission’s Public Interest Energy Research (PIER) program (PIER 500-04-005, December 2003). The project...

The purpose of this project is to evaluate and compare the performance of two types of advanced evaporative coolers to the traditional evaporative cooler. The results will allow validation...
