Energy Efficiency in Commercial Buildings

Learn how commercial buildings can incorporate whole-building design to save energy and money while enhancing performance and comfort.

This video highlights several energy-saving features of the Research Support Facility at the Energy Department's National Renewable Energy Laboratory—a model for high-performance office building design.

Energy Efficient Data Centers

Data centers provide mission-critical computing functions vital to the daily operation of top U.S. economic, scientific, and technological organizations.

Energy efficiency improvements to data centers can produce significant energy savings, reduce the load on the electric grid, and help protect the nation by increasing the reliability of critical computer operations.

Lighting Choices

People have been using the same light bulb since Thomas Edison invented it about 130 years ago. Today, there are more lighting options in stores that will save you energy and money.

Daylighting

Daylighting—the use of windows or skylights for natural lighting and temperature regulation—is one building strategy that can save money for homeowners and businesses.

Highly efficient, strategically placed windows maximize the use of natural daylight in a building, lowering the need for artificial lighting without causing heating or cooling problems.

Home Energy Assessments

A home energy checkup helps owners determine where their house is losing energy and money - and how such problems can be corrected to make the home more energy efficient.

A professional technician - often called an energy auditor - can give your home a checkup. You can also do some of the steps yourself.
