, yet easy to use building energy use analysis tool which provides professional-level results with an affordable level of effort.
This freeware tool was designed to allow you to perform detailed analysis of today's state-of-the-art building design technologies using today's most sophisticated building energy use simulation techniques but without requiring extensive experience in the "art" of building performance modeling. This is accomplished by combining a building creation wizard, an energy efficiency measure (EEM) wizard and a graphical results display module with an enhanced DOE-2-derived building energy use simulation program.

The efficiency of fossil fuel based electricity production averages 34% (although new combined cycle plants can exceed 50% efficiency). The ultimate efficiency of any building pulling electricity from the grid is limited by that number.

A cool storage thermal energy storage system (TES) provides a means for shifting all or part of a facility’s cooling energy use to off-peak hours, when energy costs are lower and cooling systems can potentially run more efficiently. A TES system uses cooling equipment at night to remove heat from a thermal reservoir of chilled water or ice, which can then be used for space cooling throughout the day.
