Predicting the energy performance of
a new building is a complicated project.
Computer-based energy simulations
are carried out routinely for large
institutional-scale projects, but they
require expertise with complex software
and days (or weeks) of data input.
Such an effort has generally been too
expensive and time-consuming for
homes or small commercial buildings.
But not anymore. A new software
package for personal computers,
Energy-10, puts detailed building energy
analysis within the reach of any residential
designer. With Energy-10
software, the analyses that used to take
weeks now take a few hours.
Equipped with an extensive database
of climate data for hundreds of North
American locations, Energy-10 enables
builders anywhere on the continent to
easily design homes that use 30% to
