Heating and air conditioning -- an $11 billion industry in America -- accounts for 5% of domestic energy use. A new technology showcased at the Energy Department's Cleantech University Prize competition has the potential to significantly cut down on appliance degradation and increase efficiency.
Building energy modeling—computer simulation of building energy use given a description of its architecture, lighting and mechanical systems, occupancy and use, and local weather— is a powerful tool for architects and mechanical engineers. Energy modeling supports the design of buildings that operate at significantly higher levels of energy efficiency for little or no upfront costs.
Today’s housing market is incredibly competitive. Constructing homes that sell and that continue to delight homeowners for years to come is a challenge.
Motivated, leading-edge builders are using innovative energy-saving solutions and strategies to differentiate themselves and their products by building zero energy-ready homes. These high-performance homes are so efficient they can offset most or all annual energy consumption with a simple renewable energy system, like solar.
Energy Department's Challenge Home Student Design Competition aims to inspire the next generation of architects, engineers, construction managers, and entrepreneurs to design homes that meet requirements for zero energy ready performance that are affordable and market-ready.
Find out how the Energy Department is working to improve the energy efficiency, design, construction and operation of high-performance commercial buildings through research at Lawrence Berkeley National Laboratory's new FLEXLAB, Facility for Low Energy Experiments in Buildings.
The Energy Department’s Building America program provides practical guidance and research to assist housing professionals transform our nation’s housing stock into energy-efficient, state-of-the-art models for businesses and homeowners. Applying building-science solutions will improve energy performance and quality of new and existing homes.
With more than 120 participants, the Energy Department’s Better Buildings Challenge is making America more sustainable by transforming how organizations improve energy performance at facilities throughout the country all while saving money and creating jobs.
Autodesk has translated EnergyPlus’ 600,000 lines of computer code into C++, one of the world’s most popular programming languages. The change increases accessibility of EnergyPlus to many more developers, who can customize their own programs to identify potential energy savings in buildings throughout the country.
The Energy Department's Building Technologies Office partners with national laboratories, industry, and universities to advance research, development, and commercialization activities for projects expected to reach the marketplace in five years or less.
The Energy Systems Integrations Facility (ESIF) at the Energy Department's National Renewable Energy Laboratory (NREL) in Golden, Colorado, received a Leadership in Energy and Environmental Design (LEED) Platinum designation.
This year’s Solid State Lighting Market Introduction Workshop, to be held November 13-14 in Portland, Oregon, will include expert guidance from industry leaders and the Energy Department's national laboratories.
