Reducing the energy consumption of the nation's buildings and resulting carbon emissions is essential to achieving a sustainable clean energy future. To address the enormous challenge, Oak Ridge National Laboratory is focused on developing new building technologies enabling grid-interactive efficient buildings that provide beneficial effects to energy security and affordability, resilience, environment, and U.S. economy.
There are over 120 million buildings in the nation that account for 39% of U.S. carbon emissions and consume approximately 40% of the nation's total primary energy, 73% of electricity, and 55% of natural gas (34% of natural gas excluding gas used to generate electricity consumed in buildings). The DOE’s Building Technologies Office’s long-term goal is to reduce this energy consumption of U.S. buildings by 50% and ORNL is contributing to the goal through delivering scientific discoveries and technical breakthroughs to accelerate affordable building energy efficiency solutions from materials, components, and systems to whole building and community integration.
ORNL’s building technologies R&D efforts include the development of current and next-generation technologies encompassing building equipment, passive and dynamic envelopes, advanced energy storage, building energy modeling, sensors, transactive controls and improved energy management and market transformation in all these areas.
