Zero Energy Buildings Basics

Zero energy buildings produce at least as much energy as they consume on an annual basis. They do this by incorporating state-of-the-art energy efficiency and renewable energy technologies.

Zero energy buildings also can produce a surplus of energy over the year which contributes significantly less to greenhouse gases than traditional buildings.

Zero energy buildings use renewable technologies such as solar and wind to produce energy while reducing the overall use of energy with highly efficient HVAC and lighting systems.

The zero energy goal is gaining momentum and becoming more practical as the costs of alternative energy technologies decrease and the costs of traditional fossil fuels increase. Corporate goals, as well as regulatory mandates, are encouraging many commercial businesses and government agencies to move toward zero energy buildings.
