Fact Sheet

Published / Updated:

A passive solar designed home utilizes solar heat gain in the winter to warm the interior of a home, controls solar heat gain in the summer, and facilitates daylighting, natural ventilation, and nighttime cooling to keep a home comfortably cool in the summer. As a result, energy is saved by maximizing the home's natural heating, cooling, ventilation, and lighting options.  Additionally, homes featuring a good passive solar design are typically healthier and more comfortable.

This fact sheet from Build It Green describes the following five considerations in designing the basic form and layout of a passive solar designed home:

  • Shape
  • Orientation
  • Location
  • Aperture
  • Roof overhangs
