How to save energy in Existing Buildings

  1. 1. By AmirAshkanSemyary Period#5 (1)
  2. 2. Why do we need to save energy?  Saving energy plays a big role in saving the money used in energy extraction.(2)  Helps reducing green house emission as well as reduction of air pollution (from burning coal or fossil fuels).(2)  We should consume less energy and use it more efficiently so that the future generations can use it as well.(2)  Non-renewable resources last longer.(2)
  3. 3. Heat houses more efficiently  Using a geothermal heat pump that transfers the heat stored in the earth to our houses (heat transferred from the ground.(3)  Passive solar heating(Energy extracted from the sun).3  Using a high efficiency natural gas furnace (about 85- 98% more efficient.(3) (4)
  4. 4. Heating houses more efficiently  Advantage: Clean source of heating.(3)  Disadvantage:   1)Expensive to purchase and install.(3) 2)Depending on model ,efficiency drops when the outside temperature is very low.(3) (7)
  5. 5. Stop other heating and cooling losses  Insulating our roofs and walls.(5)  Draw unwanted moisture from the crawl spaces beneath the house.(5)  Get rid of the cooling ducts in our attics( Attic insulation should be at least 30 centimeters)-(5)  Advantages: 1)The heat now is more efficiently used.(5) 2)Less running cost.(5)  Disadvantage: Cost of installation.(5)
  6. 6. Heat water more efficiently  Installing a mounted solar hot water heater.(6)  Use a tankless instant water heater which uses natural gas or LPG.(6)  Heating water directly is better than indirectly.(6)  Advantage: Less heat is used to heat our water.(6)  Disadvantage: Cost of installation(6) (8)
