     Windows
     

     Energy efficient windows have multiple layers of glass. The reason for this is because the more layers of glass you have the better it insulates the house. Three or four layers of glass are one of the best because you have more airspace in between layers.

     
     
     A smaller airspace doesn't insulate the building as well as a thicker airspace would. The thickest an airspace should be is 1 inch because any thicker than that will cause the glass of the window to no longer insulate the building.

Don't use low e glass on south windows, but low e glass on the other sides of the house is fine. North windows should be made large to bring in the sun light. East and West windows should have shade to protect the winds from coming into the building.
     The advantages of energy efficient windows are that they reduce heat loss in wintertime and reduce heat gain in the summer time.
     

Lights
     

     Energy efficient lights are used in homes because they:
1. Use less energy than standard bulbs
2. Lower the electrical bills
3. Produce just as much light as standard bulbs
4. Last longer than regular light bulbs

     Fluorescent bulbs are more efficient than regular bulbs because they don't produce as much heat. They are thin lights that are tubular shaped. Their life span is 10,000 to 20,000 hours, which means that they last 10 times longer than the regular bulb.
     Compact fluorescent bulbs provide just as much light as standard bulbs but they use one fourth (1/4) the energy. For example, a 15-watt compact bulb produces the same amount of light as a 60-watt normal bulb. Just like the fluorescent bulb, they are energy efficient and less heat is given off from them.
     Lights in a year don't usually show up as a
