Sustainable By Design provides the following suite of shareware tools to aid with solar design and building-energy analysis:
- SunAngle determines the position of the sun at any time of day at any location on Earth.
- SunPosition calculates sun angles over the course of a year.
- SunPath produces graphic representations of the sun's course through the sky.
- Overhang Design analyzes the performance of simple window overhangs.
- Window Heat Gain calculates the solar-thermal gain through windows.
- CFL Economics compares the lifetime operating costs of compact fluorescent lamps and incandescent lamps.
