Research Themes +
Energy Technologies Area (ETA) researchers are continually building on the strong scientific foundation we have developed over the past 50 years. We address the world’s most pressing climate challenges by bringing to market energy-efficient innovations across the buildings, transportation, and industrial sectors. ETA is at the forefront of developing better batteries for electric vehicles; improving the country's aging electrical grid and innovating distributed energy and storage solutions; developing grid-interactive, efficient buildings; and providing the most comprehensive market and data analysis worldwide for renewable technologies like wind and solar.
Strategic Initiatives +
The Energy Technologies Area (ETA) Strategic Plan is the guiding force for our research and development for the next ten years. It clearly charts a path toward clean-energy solutions and focuses on five detailed Strategic Initiatives. The Plan provides an in-depth look at how ETA is accelerating research to provide affordable, clean energy to all while accomplishing deep, economy-wide decarbonization, looking to avoid a rise in global average temperature while simultaneously developing solutions to increase humanity's resilience to extreme weather volatility.

Abstract

Fenestration performance in nonresidential buildings in hot climates is often a large cooling load liability. Proper fenestration design and the use of daylight-responsive dimming controls on electric lights can, in addition to drastically reducing lighting energy, lower cooling loads,speak electrical demand, operating costs, chiller sizes, and first costs. Using the building energy simulation programs DOE-2.1B and DOE-2.1C , we first discuss lighting energy savings from daylighting. The effects of fenestration parameters on cooling loads, total energy use, peak demand, chiller sizes, and initial and operating costs are also discussed. The impact of daylighting, as compared to electric lighting, on cooling requirements is discussed as a function of glazing characteristics, location, and shading systems.
