Welcome to DOE Renewable Energy Online Training Center

In partnership with the private sector, state and local government, national laboratories, and universities, the Building Technologies Program works to improve the efficiency of buildings and the equipment, components, and systems within them. The program supports R&D activities and provides tools, guidelines, training, and access to technical and financial resources.

The Building Technologies Program Multi-Year Program outlines the technology portfolio and activities that are necessary to achieve our strategic goal of net-zero energy buildings (ZEB) at low incremental cost by 2025. Achieving long-term ZEB goals depends upon not only integrating and optimizing the best available technologies, but also depends on the development of new technologies and solutions to bridge the gap between today's energy efficient buildings and ZEB.
