How to be an Energy No Load Tim Fulford Environmental Project Manager Trident Technical College

Did you know? In the U.S. alone, buildings account for: 72% of electricity consumption

Home Energy Use Source: Home energy % usage - US Department of Energy Discuss the fact the HVAC is trying to go against the outside temperature. And that is loses energy. Source: Home energy % usage - US Department of Energy

Top Energy Wasters Heating and Cooling (49%) Air Leaks Inefficient HVAC Low levels of Insulation Single Pane Windows Water Heating (23%) Temperature Water Usage Lighting & Appliance(18%) Incandescent Lights Appliances Vampire Loads

1 Kilowatt-hour costs 10 cents What does 10 cents buy? Run time for 10 cents 13 watt CFL - 77 hours 24 watt laptop - 42 hours 90 watt ceiling fan - 11 hours 100 watt light bulb - 10 hours 300 watt Plasma TV - 3 ½ hours 3 ton high efficiency AC - 22 minutes 3 ton low efficiency AC - 15 minutes A heat pump in strip heating mode = 5 minutes for 10 cents.

Seal Air Leaks Attic access doors Knee-walls Plumbing, electrical penetrations Recessed can lights Chimney/Fireplace dampers Windows and doors Almost every home has a large # of hidden air leaks that rob it of heating and cooling energy

Add Insulation Increase Levels Ceilings – R38 Floors – R19 Walls – R13 Optional Install Radiant Barrier to reduce cooling loads Radiant barrier save 10 -15% on cooling cost

Windows Single Pane Windows Use trees to reduce heat gain on windows facing south Plant shrubs in front of windows facing east and west Caulk gaps Radiant barrier save 10 -15% on cooling cost

Efficient HVAC Operation HVAC Technician Correct charge, air flow and size Seal ductwork Replace with 13 SEER or higher Homeowner Replace filters – monthly Turn system off when not at home Clear area around outside unit

Water Heating Reduce tank temp to 120oF Use Timer control/turnoff when away Insulate tank and pipes Install Low flow shower heads Replace with high efficiency unit Replace with Solar Thermal power and save $300-400/year

Lighting & Appliances Replace Incandescent with CFL’s Use natural light Operate ceiling fans only when room occupied Turn off heat cycle on dishwasher Replace existing washing machine with front load Use cold water

Vampire Loads Satellite TV box - 40 Watts DVD/VCR – 10 watts Printer – 8 watts Digital Cable Box – 15 watts Microwave w/clock – 8 watts Did you know? The American home draws between 50 – 150 watts of vampire loads.

How many CFL’s does it take to replace an incandescent?

Annual $avings Use 8 CFL’s = $130 Set thermostat 74o to 78o = $295 Reduce hot water from 130o to 120o = $60 Replace 10 SEER with 15 SEER HVAC = $220 Study based on a 1600 square foot home w/annual consumption of 18,000 kWh. Set thermostat 74o to 78o = $295 74o to 68o = $250 Seal leaky ducts = $250 Seal air leaks = $220 Increase insulation R11 to R30 = $70 This was a study on a 1600 square foot home w/annual consumption of 18,000 kWh.
