See how much energy and money and carbon you can save by making various design or remodeling changes to your home with this free new easy-to-use program. You can draw in the floor plan of your own house, then click and drag your windows to their correct location. You can select from lists of typical wall and roof construction. For advanced users there are more detailed design data input options and output display graphics from the original Solar-5. HEED self installs as a stand-alone program on everything from Windows XP or later and Macintosh OS X 10.6 or later. HEED also runs in Spanish (HEED en Español).
If you already have HEED running, you can install this new version in the same folder, and all your data will be preserved. Just hit Recalculate Old Projects to update each scheme.
HEED is free.
