How does passive solar design work?

Architectural designs that enhance absorption of solar energy by using/adjusting for natural changes that occur throughout the year without requiring mechanical changes

- design overhangs on buildings that block summer sunlight but allow winter sunlight.

- build wall that absorbs solar energy and heats room.

- use trees that lose leaves in winter - plant on sunny side of building → summer shade to cool buildings.

- natural lighting through skylights → glazing on glass transmits light and gives insulation
