Commercial buildings have high energy needs and can put great strain on the nation's power grids during peak periods. Developing more efficient buildings helps ensure a steady supply of affordable power and significantly lowers operating costs for business.

The Department of Energy works to develop and deploy cost-effective solutions that help increase efficiency and reduce the cost of powering commercial buildings. Through research, best practices and the Better Buildings Initiative, the Department is working with businesses to create a cleaner, more sustainable future.
