Achieving DOE’s high-level goals of combating climate change, creating clean energy union jobs, and promoting energy justice, requires improving the energy efficiency of America’s nearly 130 million buildings. The Building Technologies Office (BTO) is dedicated to growing the American workforce that manufactures, deploys, installs, and repairs efficient building technologies in residential and commercial buildings. BTO envisions a nationally representative building efficiency workforce of sufficient size, skill, and compensation to carry out an equitable transition of America’s buildings infrastructure to achieve net-zero greenhouse gas emissions no later than 2050.
