1 Saving Home Energy Easy Ways to Help Yourself Part 2
2 Save energy now Energy saving methods Low initial cost/no cost Moderate initial cost Apartments and Homes
3 Human Thermal Comfort is determined by six variables: air temperature air velocity relative humidity clothing metabolic rate (activity level) mean radiant temperature Fanger, P.O., Thermal Comfort, McGraw Hill C., 1972, pag 256. Apartments and Homes
4 Low cost ways to save energy Personal attitude & behavior Wear layered warm clothes indoors during winter Take short showers instead of baths Close windows & doors (train family) Apartments and Homes
5 No Cost… Low Cost Reducing heating costs –Turn down thermostat –Unblock and clean heating ducts and return air vents –Place reflectors behind radiators –Leave south-facing window curtains open in winter and closed in summer to collect or prevent solar heat gain. Apartments and Homes
6 No Cost… Low Cost More Keeping Warm Tips –Clean and inspect furnace annually –Use foil tape to repair heating ducts –Use ceiling fans to circulate warm air –Check hot air furnace filters every 1 to 3 months –Close off unused rooms * * Caution with baseboard heating systems
7 Checking for Drafts Turn on a bathroom or kitchen exhaust fan Attach a 6 piece of tissue paper to a pencil and hold next to a window or outlet. Observe the paper moving slightly to show areas that need to be insulated.
9 Weatherize Against Infiltration Caulk at any joint or penetration to the exterior - wiring, pipes & duct penetrations in the attic, under floor & through walls Caulk where dissimilar materials meet Weatherstrip doors, windows, & sills Vapor barriers: –20 Gallons per day of moisture evaporates from crawl space into air of 1400 sq. ft. home Install 4-6 mil plastic on warm-in-winter side of the living space
10 Caulking & Weather Stripping Caulking and Weatherstripping will payback in one year and make you more comfortable
11 Storm Windows & Banking House Plastic sheeting Tar paper Bags of leaves Bales of straw or hay Solid foam board Combination Windows Glass Storm Windows Plastic Storm Windows (outside or inside) Caution: Do not cover propane clothes dryer vent, or other gas fired appliance vents with banking material
13 Effect of Window Treatments Apartments and Homes
14 Using Window Treatments Heavy Drapes Roman Shades Insulation Boards Apartments and Homes
15 Door Draft Stoppers Window Draft Snakes Fill with –foam pipe insulation –Sand –Plastic bags Apartments and Homes
16 No Cost… Low Cost Apartments and Homes Water Heating –Turn down temperature on hot water heater (110 o to 120 o F) –Drain a few gallons from the bottom of your hot water heating tank –If leaving for more than two days, turn off water heater –Install low flow showerheads and aerators in your faucets –Repair all leaking faucets –Insulate your water heater* and supply pipes *not recommended to insulate gas water heaters
17 Low Cost – No Cost Apartments and Homes Lighting –Keep lights clean; shut off when not in use –Compact florescent bulbs –Timers Other appliances –Use power strip for computer, television, VCR, recorders, satellite, etc. so you can turn them off completely when not in use.
18 Lighting Watt – amount of energy used Lumen – amount of light produced CFLs – cost 4x more that incandescent, last 10x longer, use ¼ the energy Incandescent watts Fluorescent watts Light Output lumens 4010450 75201100 150282600 http://www.energystar.gov/index.cfm?c=cfls.pr_cfls
19 Holiday Lighting… Light Emitting Diode (LED) *typical amount of lighting used on the exterior and interior for one holiday season. ** Assuming 240 hours of use (6 hours of use for 40 days) at an electric rate of $0.16.kWh) Bulb TypeNo. Feet Used* Energy Usage (watts) Av. Operating Cost** C7 5003500$547 C7 LED 500116$18 Mini Incandescent 500900$141 LED Mini 50067$11 Apartments and Homes
20 Refrigerator / Freezer –Remove frost from freezer –Replace worn gaskets –Keep full –Clean the coils Consider replacing appliances that are over 20 years old and/or in need of major repairs with energy star models Apartments and Homes

22 Save energy in the kitchen Match pan size to heating element When cooking small meal, use microwave, crock pot or toaster oven Use the smallest pan necessary for the job Keep the lid on to hold in heat Reduce cooking time by defrosting food in refrigerator first Avoid looking in the oven as you cook!

23 Save energy while doing dishes Use energy saving cycles Use no-heat dry cycle Dont pre-rinse Wash full loads Load dishes according to manufacturers instructions If washing dishes by hand, turn water on only to rinse Apartments and Homes
24 Save energy in the laundry room Use lower temperature settings Wash in cold water whenever possible Load the washer to capacity Dont over dry clothes Dry two or more loads in a row Clean dryer filter after each use Dry full loads Clean exhaust vents Hang clothes outside!

25 Fireplaces Put tight-fitting doors on open fireplaces Insert inflatable pillows into fireplace to block off chimney Use caution when planning to use the fireplace since wildlife may have plugged the chimney
26 Programmable Thermostats More convenient and accurate than manual thermostats and: Improve comfort Contain no mercury Save energy and money on utility bills Save 1% annually for each degree setback for 8 hours per day
27 Repair Ductwork Ducts might need repair and sealing when: –Rooms are too warm or too cold –High summer and winter utility bills –Little or no air flow from registers in some rooms –Air filters gets dirty quickly –Streaks of dust at registers or duct connections –No insulation on visible ducts (attic or crawl space) –Flexible ducts are tangled or kinked
28 Cost / Benefit of Attic Insulation Cost R-27Cost R-47 Fuel Costs (15% estimate savings) $2,408$2,268 Insulation (40 packs of loose fill cellulose @ $8.88) $355 Savings estimate$140 per year Time to pay back insulation costs 2.5 years
29 Insulation with ventilation to reduce ice dams Ventilation Requirements- Roof 1 square foot of ventilation opening per each 150 square foot of roof area ½ at eave ½ at roof edge or higher area of roof is ideal
30 Rating Systems Doors and Windows –National Fenestration Rating Council (NFRC) Labeling Furnace or boiler –Annual Fuel Utilization Efficiency (AFUE) Water Heater –EER is a measurement of the efficiency of the water heater based on 64 gallons of hot water per day Air Conditioner –Seasonal Energy Efficiency Rating (SEER) Appliances –Energy Star
