3. How it Works
What is It?
Passive Solar Heating uses a building’s architectural features to effectively capture sunlight for heating a house, using few or no mechanical devices to capture or store energy

4. How it Works Types of Heating Direct Gain (windows)
capture direct sunlight
Indirect Gain (trombe walls)
sun heats barrier which heats house
Isolated Gain (sunspaces)
sun heats detached room
heat circulated through house

5. Key Features Building Orientation (East-West) Windows (size/placement)
Good Insulation
Heat Absorbent Materials (masonry, water)

6. Advantages Low cost (initial and operating) Environmentally friendly
Simple, yet effective

7. Disadvantages Unwanted heat in summer Heat loss through windows
Difficult to convert house to passive solar heating
