The advantages of passive solar lighting

  1. 1. The Advantages of Passive Solar Lighting (Daylighting)<br />TJ Purewal<br />
  2. 2. What is Passive Solar Lighting?<br /><ul><li>Passive Solar Lighting, or Daylighting is the use of direct, diffused or reflected sunlight to provide added lighting for buildings.
  3. 3. Daylighting can fully replace electric lights.</li></li></ul><li>Advantages of Daylighting<br />
  4. 4. Saves Costs<br /><ul><li>Passive solar energy can reduce monthly energy expenses by 13.8 percent.
  5. 5. All heat and light generated by your passive solar system is free.</li></li></ul><li>No Equipment to Buy or Maintain<br /><ul><li>Homes with passive solar systems do not require central heating or air conditioning systems. 
  6. 6. Passive solar systems require no maintenance, as there are no filters to change or ducts to clean.</li></li></ul><li>Fossil Fuels Conserved<br /><ul><li>Homeowners who get their power from local utility companies ultimately rely on fossil fuels for energy. Therefore, using passive daylighting conserves fossil fuels.</li></li></ul><li>Environmental Benefits<br /><ul><li>Passive solar design is a completely clean energy source. It produces no harmful fumes, pollutants or emissions that can harm the environment.</li></li></ul><li>Daylighting Techniques<br />
  7. 7. Effective and Successful Daylighting is achieved through…<br /><ul><li>Positioning and sizing your windows to allow for sufficient natural light to enter your home.
  8. 8. Using exterior shading to diffuse the sunlight</li></li></ul><li>Solar Daylighting Windows<br /><ul><li>Solar daylighting primarily occurs through large windows. Buildings that use solar daylighting require specific placement and spacing of windows. For example, windows that are higher up on a wall distribute sunlight better.</li></li></ul><li>Clerestory Windows<br />
