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

This study compared fixed Cooling Seasonal Performance Factors (CSPF) calculated using a general outdoor temperature distribution to those calculated considering specific climates and the use of Room Air Conditioners (RAC). Results indicate that tailoring CSPF calculation to specific climates is key to better communicating RAC efficiencies to stakeholders. Additionally, using Building Performance Simulation (BPS) was proved as an innovative approach within this scope, since it can tailor CSPF calculation to specific hours when indoor conditions are more likely to demand cooling. This approach also highlighted equipmentrelated outcomes that static evaluations could not detect.
