Buildings Energy Efficiency

Researchers, in close cooperation with industry, develop technologies for buildings that increase energy efficiency, and improve the comfort, health, and safety of building occupants.

Researchers at the Environmental Energy Technologies Division work to transfer new energy-efficient building technologies from the laboratory to the real world, and stimulate the use of underutilized, high-performance technologies through innovative deployment programs.

Commercial building systems research explores different ways to integrate the efforts of the other research areas (windows, lighting and simulations) with the goal of developing coherent and innovative building construction and design techniques.

On warm summer days, a city can be 6 to 8°F warmer than its surrounding areas. This effect is called the urban heat island. Cool roof materials, pavements, and vegetation can reduce the heat island effect, save energy and reduce smog formation. The goal of this research is to develop cool materials to save energy and money.

Demand response (DR) is a set of time-dependent activities that reduce or shift electricity use to improve electric grid reliability, manage electricity costs, and provide systems that encourage load shifting or shedding during times when the electric grid is near its capacity or electric prices are high. Demand Response Research Center's objective is to develop, prioritize, conduct, and disseminate research that develops broad knowledge to facilitate demand response.

EETD’s energy efficiency program and market trends research includes technical, economic and policy analysis to inform public and private decision-making on public-interest issues related to utility-sector energy efficiency programs and regulation, and government-funded energy efficiency initiatives.

EETD’s research on high technology buildings and industrial facilities is aimed at reducing energy consumed by the industrial sector in manufacturing facilities, including high technology industries such as data centers, cleanrooms in the such industries as electronics and pharmaceutical manufacturing, and laboratories, improving the competitiveness of U.S. industry.

Lighting research is aimed at improving the energy efficiency of lighting systems in buildings and homes across the nation. The goal is to reduce lighting energy consumption by 50% over twenty years by improving the efficiency of light sources, and controlling and delivering illumination so that it is available, where and when needed, and at the required intensity.

Researchers develop whole-building energy simulation software programs that allow architects and building engineers to design or retrofit buildings for maximum energy efficiency and occupant comfort.

EETD’s research in residential buildings addresses problems associated with whole-building integration involving modeling, measurement, design, and operation. Areas of research include the movement of air and associated penalties involving distribution of pollutants, energy and fresh air.

Researchers develop whole-building energy simulation software programs that allow architects and building engineers to design or retrofit buildings for maximum energy efficiency and occupant comfort.

Research on sustainable federal operations supports the implementation of sustainable policies and practices in the public sector. This work serves as a bridge between the technology development of Department of Energy’s National Laboratories and the operational needs of public sector.

Windows research is aimed at improving energy efficiency in buildings and homes across the nation.
