Building Energy Tools from the Department of Energy

If you design or build buildings, you’ll find a very full toolbox at the U.S. Department of Energy. It has posted a wide variety of software and calculators to help evaluate the life-cycle potential of different energy efficiency and renewable energy technologies. The tools help designers develop energy strategies in new or existing buildings. Some are available for free, others for a fee.

And if you’ve developed a tool along these lines, DOE invites you to submit it.
