Live reporting - Energy $ense - heating, cooling tips

Electric reductions
  • phantom load reduction with power strips
  • determine power eaters with "Kill a watt" meter and economize use
  • energy appliance purchases
buy Energy Star appliances (www.energystar.gov)

Appliance tips
  • don't buy a plasma TV (uses 3-4 times as much than conventional)
  • gas-fired clothes dryer
  • front loading washing
heating & cooling purchases
  • programmable thermostat (rebate available from local utility)
  • new furnace or heat pump
heating & cooling tips
  • boiler, efficient, tuned and cleaned
  • insulation, windows, don't let heat escape
Weatherization
  • sealing of air leaks (attic, basements)
  • insulation installation
air leakage paths
  • air comes into the basement through the windows, cracks in the walls
  • warm air rises and will go out where it can
homeowners who have insulated and did not see an improvement in energy usage, usually had air leaks that were not properly addressed

Blower door Air Leakage analysis
helps to find big leaks, assess ventilation, requires training, measure leakage before and after work, can cost $4-600 for a single household

get the neighborhood together to have the contractor come in to do several at the same time and reduce the cost

Infra-red Camera
assess current level of insulation in walls and spot gaps
check results of contractor work

windows are very expensive to replace but the energy saving payback is hard to get; about 8-13% on savings

  1. One tip is to use a spin dryer instead of a tumble dryer, they use a fraction of the energy and are gentler on the clothes. More information is available at http://www.laundry-alternative.com/drying.htm
