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

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
