    • Four Basic Approaches
      • Behavioral – Lifestyle changes you can make
      • Appliances – Items you can buy
      • Weatherization Investments – Home improvements
      • Education – Reliable sources of information to help you become an educated consumer
    • Structure & Objective

    • Behavioral Lifestyle changes you can make
      • Hot water use
      • Heating & cooling
      • Lighting
      • Electric use reductions
    • Hot Water Use
      • Adjusting hot water heater
      • Insulate heater
      • Shorter showers
      • Hand dish washing
      • Wear clothes longer
      • Washing with cold water
    • Additional Hot Water Tips
      • When replacing a water heater, buy the most efficient one available, and don’t buy more capacity than you need.
      • Put “cut-off” switch on your
      • Shower head, and reduce flow when
      • full pressure is not needed.
    • Heating & Cooling
      • Turn down thermostat
      • Change A/C filter frequently
      • Regular tune up of furnace or heat pump
      • Seal windows and doors
    • Air Sealing
      • Rope caulk along edges of windows
      • Clear plastic on windows
      • Weather stripping on edges of doors
      • Plug holes in ceilings, floors, walls with caulk, fiberglass, plastic, etc.
      • Foam inserts for power sockets & switches
    • Lighting
      • CLF’s use ¼ the electricity for same amount of light, blub lasts 7 to10 times as long
      • Turn lights off when no one in room
    • Electric Reductions
      • Phantom load reduction with power strips
      • Determine power eaters with “Kill A Watt” meter and economize use
      • Energy appliance purchases
    • Energy Star Appliance Purchases www.energystar.gov
      • New hot water heater $350
      • New dish washer $450
      • New washer and dryer
      • New refrigerator $550
    • Additional Appliance Tips
      • DON’T buy a plasma TV
      • Buy a gas-fired clothes dryer
      • Buy a front-loading, high-speed
      • washing machine (the clothes
      • come out much dryer, reducing
      • dryer time)
      • Turn computers & other electronics off when not in use
    • Heating & Cooling Purchases
      • New programmable thermostat $35.
      • New furnace or heat pump $3500.
    • Additional Heating & Cooling Tips
      • Boiler – efficient, well-tuned & cleaned
      • Insulation, windows – don’t let heat escape through roof, walls, windows, basement
      • Don’t waste heat – use thermostat to provide heat only when needed
    • Lighting
      • Installation of additional CFL fixtures
      • Motion detector for security
      • lighting
    • Weatherization Major Home Improvement Investments
      • Sealing air leaks
        • Attic
        • Basement
        • Plumbing stacks, walls without top plates, etc.
      • Insulation installation
        • Empty walls
        • Empty attic
    • Air Leakage Paths
      • Attics & basements usually 50%-75% of leakage
        • plumbing stacks
        • walls without top plates
        • ceiling height changes
        • chimneys
        • soffits
        • recessed lights
        • foundation walls
      • Windows and doors typically 10%-15%
    • Blower Door Air Leakage Analysis
      • Measure leakage
        • before & after
      • Help find big leaks
      • Assess ventilation
      • Requires training
      • works well with infra-red camera
    • Infra-red Camera
      • Assess current level of insulation in walls and spot gaps
      • Check results of contractor work and if additional remedial work is needed to complete job

    • Energy Saving Actions: Priorities $600-$800 - Furnace Fan if set ON all year, change to AUTO $10-$30 - Humidifier unplug – shouldn’t be needed in tight home $150-$200 - Waterbed use quilted pad, no heat $80-$160 - Stereo off when not used Annual Savings Action $75-$140 Setback Heat 8°F, 8 hrs/day Action Priorities, when applicable $100-$200 - TV off when not used (vs. background noise) $5-$20 - Fans off when room is empty in summer $40-$100 - Computer off when not used vs. screen saver $100-$250 - Freezer get rid of / unplug $125-$400 - 2 nd fridge get rid of / unplug Turning Off Appliances vs. 24x7 operation
    • Energy Retrofit Priorities $10-$40 $5-$50 Very low flow showerhead <1.8 gpm $50-$200 $5-$150 Fix hot water leak $75-$150 $15-$100 Replace 15 most used bulbs with CFLs $40-$150 $15-$100 Security Lighting: motion detector $500+ $3,200 Replace old furnace w/92% if heat >1200 th $100-$400 $500-$1,000 - w/Strategic Dense Pack in tricky homes $500+ $500+ $400-$800 $800 $1,000 $1,200 Cost $350 Insulate empty attic bypass seal, 1000 ft² $350 Insulate empty walls dense pack, 1000 ft² $75-$175 +$100 H2O Replace old Clothes Washer 1 load/day $100 Insulate attic: some existing bypass seal $75-$200 Replace old (pre-93) fridge Annual Savings Retrofit $75-$250 Air Seal using blower door High Priority Treatments when applicable
    • Energy Retrofits: Lower Priorities $10 $1,000 Cool Roof (white roof coating on flat) $50-$150 $10,000? Replace 15 old windows $50-$100 $2,000 Tankless Gas Water Heater $0-$50 $50-$600 Seal basement ducts $30-$100 $1,200 Insulate basement ceiling 1000 ft² $10-$40 $50-$600 Caulk/Weatherstrip Windows/Doors $25-$45 $400+ Replace old dishwasher $300+ $3,200 Replace old furnace w/92+% avg. use $0 $150 Tune Up Gas Furnace (annual) $30-$60 $700 Insulate attic: some existing no seal Cost Annual Savings Retrofit Lower Priority Treatments
    • Windows
      • Longer payback than other measures
      • Estimate 13% savings from new windows if no storms before, 8% if storms
      • Standard double-glazed windows only R-3, versus R-12 for cellulose in walls, cost $300-$500 per window.
      • Buy triple-glazed, R-5, $460 and up per window.
      • Good installation important – fill cavities with loose insulation
    • Window Quilts
