The Building Technologies Office (BTO) invests in technology research and development activities that can dramatically reduce energy consumption and energy waste in buildings. Buildings in the United States use nearly 40 quadrillion British thermal units (Btu) of energy for space heating and cooling, lighting, and appliances, an amount equivalent to the annual amount of electricity delivered by more than 3,800 500-megawatt coal-fired power plants. The BTO technology portfolio aims to help reduce building energy requirements by 50% through the use of improved appliances; windows, walls, and roofs; space heating and cooling; lighting; and whole building design strategies.
