Look at Best Practices

Businesses around the U.S. have implemented energy-efficiency projects in conjunction with the U.S. Department of Energy, especially manufacturing plants where the potential savings are huge. When the project is complete, a case study is published online to show how it reduced energy consumption and the building’s environmental impact.

The U.S. Department of Energy site allows you to search for case studies by industry.

Other sites, such as the Lennox Commercial website, provide real-life case studies for businesses such as retail stores, restaurants and office buildings.
