what is passive solar energy
What is Passive Solar Energy
  • Passive Solar Energy is the use of solar energy to heat a home with little or no mechanical assistance.
  • Homes constructed with solar design elements, capture sunlight and utilizes the natural movement of heat and air to maintain comfortable temperatures.
5 basic solar design principles
5 Basic Solar Design Principles

Orientation

  • Longer axis of home parallel to east/west direction
  • Longer dimension of house faces south

Overhangs and Shading

  • Properly sized overhangs provide shading when cooling is needed and allows sunlight in when heating is needed
  • Other methods of shading: insulated drapes or shutters, exterior shades, awnings, and landscaping

Insulation

  • To ensure that a comfortable temperature is maintained within the house

Windows

  • Optimum position for maximum solar benefits is true south
  • Position majority of windows on the south-facing wall to collect warm solar energy and to let in fresh air
  • Limit north/east/west windows to keep house well insulated

Thermal Mass

  • A solid or liquid material that absorbs and stores warmth or coolness until it is needed later on
  • To prevent large changes in indoor temperatures as outdoor temp. rises and falls, balance the amount of square footage of south-facing glass to the amount of effective thermal masses
advantages
Advantages
  • Environmentally-Friendly
  • Attractive living environment: large windows/views, open floor plans, and sunny interiors
  • Lower energy bills, year-round
  • High owner satisfaction, increases re-sale value of the house
disadvantages
Disadvantages
  • Without help of experienced passive solar designer, building a home that utilizes passive solar energy can be very difficult
  • A small mistake can be costly
  • Unwanted heat during the summer increases energy use in the building due to added load on the A/C
