Buildings that are more energy-efficient, comfortable, and affordable…that's the goal of DOE's Office of Building Technology, State and Community Programs (BTS).

To accelerate the development and wide application of energy efficiency measures, BTS:

• Conducts R&D on technologies and concepts for energy efficiency, working closely with the building industry and with manufacturers of materials, equipment, and appliances
• Promotes energy/money saving opportunities to both builders and buyers of homes and commercial buildings
• Works with State and local regulatory groups to improve building codes, appliance standards, and guidelines for efficient energy use
• Provides support and grants to States and communities for deployment of energy efficient technologies and practices
