Unfortunately, alarge portion of that energy is wasted.And electricity generated by fossil fuelsfor a single home puts more carbon dioxide into the air than two average cars. Byusing a few inexpensive energy-efficientmeasures, you can reduce your energybills by 10% to 50%, and at the sametime, help reduce air pollution.The key to achieving thesesavings is a whole-house energy efficiency plan. To takea whole-house approach, view yourhome as an energy system with interdependent parts. For example,your heating system is not just afurnace—it’s aheat-deliverysystem thatstarts at the furnace and delivers heatthroughout yourhome using a network of ducts. Youmay have a top-ofthe-line, energy-efficient furnace, but ifthe ducts leak and areuninsulated, and yourwalls, attic, windows,and doors are uninsulated, your energy billswill remain high. Takinga whole-house approachto saving energy ensuresthat dollars you invest inenergy efficiency are wisely spent.Energy-efficient improvements notonly make your home more comfortable,they can yield long-term financialrewards. Reduced operating costs morethan make up for the higher price ofenergy-efficient appliances and improvements over their lifetimes. Improvementsmay also qualify you for an energy efficiency mortgage, which allows lenders touse a higher-than-normal debt-to-incomeratio to calculate loan potential. In addition, your home will likely have a higherresale value.This booklet shows you how easy itis to reduce your home energy use. It isa guide to easy, practical solutions forsaving energy throughout your home,from the insulating system that surroundsit to the appliances and lights inside.Please, take a few moments to read thevaluable tips in this booklet that will saveyou energy and money and,in many cases, help theenvironment by reducingpollution and conservingour natural resources.Whole-House Energy PlanPrioritize your whole-house plan byviewing your home as an energysystem with interdependent parts.IntroductionFlorida Solar Energy Center (FSEC)1679 Clearlake RoadCocoa, FL 32922-5703Phone: (321) 638-1000Fax: (321) 638-1010E-mail: info@fsec.ucf.eduwww.fsec.ucf.edu1

Your Home ’s Energy UseThe first step to taking a whole-houseenergy efficiency approach is to find outwhich parts of your house use the mostenergy. A home energy audit will showyou where these are and suggest themost effective measures for reducingyour energy costs. You can conduct asimple home energy audit yourself, youcan contact your local utility, or you cancall an independent energy auditor fora more comprehensive examination.Waterheating14%Lighting,cooking,and otherappliances33%Heating andcooling44%After you have identified placeswhere your home is losing energy, assignpriorities to your energy needs by askingyourself a few important questions: How much money do you spend onenergy?Refrigerator9%Energy Auditing TipsYour Home’s Energy Use Study your family’s lighting needs anduse patterns, paying special attentionto high-use areas such as the livingroom, kitchen, and exterior lighting.Look for ways to use daylighting,reduce the time the lights are on, andreplace incandescent bulbs and fixtureswith compact or standard fluorescentlamps.Formulating Your PlanHow We Use Energy In Our Homes(based on national averages)The largest portion of a utility bill for a typicalhouse is for heating and cooling. Check the level of insulation in yourexterior and basement walls, ceilings,attic, floors, and crawl spaces. Contactyour local contractor for advice onhow to check your insulation levels. Check for holes or cracks around yourwalls, ceilings, windows, doors, lightand plumbing fixtures, switches, andelectrical outlets that can leak air intoor out of your home. Check for open fireplace dampers.2 Make sure your appliances and heatingand cooling systems are properlymaintained. Where are your greatest energy losses?

Insulation and WeatherizationChecking your home’s insulating systemis one of the fastest and most costefficient ways to use a whole-houseapproach to reduce energy waste andmaximize your energy dollars. A goodinsulating system includes a combinationof products and construction techniquesthat provide a home with thermal performance, protect it against air infiltration,and control moisture. You can increasethe comfort of your home while reducingyour heating and cooling needs by upto 30% by investing just a few hundreddollars in proper insulation and weatherization products.InsulationFirst, check the insulation in your attic,ceilings, exterior and basement walls,floors, and crawl spaces to see if it meetsthe levels recommended for your area.Insulation is measured in R-values—thehigher the R-value, the better your wallsand roof will resist the transfer of heat.The U.S. Department of Energy (DOE)recommends ranges of R-values basedon local heating and cooling costs andclimate conditions in different areas ofthe nation. The map and chart on pages 6and 7 show the DOE recommendationsfor your area. State and local codes inInsulation and WeatherizationAtticWallsFloorsCrawl spaceBasementWhere to InsulateAdding insulation in the areas shown here may be the best way to improve your home’s energyefficiency.4

Insulation Tips Consider factors such as your climate,building design, and budget when selecting insulation R-value for your home.Should I insulate my home?The answer is probably “yes” if you: Have an older home and haven’tadded insulation: in a recent survey,only 20% of homes built before1980 were well insulated Are uncomfortably cold in thewinter or hot in the summer—adding insulation creates a moreuniform temperature and increasescomfort Build a new house or addition, orinstall new siding or roofing Pay excessive energy bills Are bothered by noise from theoutdoors—insulation helps tomuffle sound Are concerned about the effect ofenergy use on the environment. Use higher density insulation, such asrigid foam boards, in cathedral ceilingsand on exterior walls. Ventilation plays a large role in providing moisture control and reducingsummer cooling bills. Attic vents canbe installed along the entire ceiling cavity to help ensure proper airflow fromthe soffit to the attic to make a homemore comfortable and energy efficient. Recessed light fixtures can be a majorsource of heat loss, but you need to becareful how close you place insulationnext to a fixture unless it is marked“I.C.”—designed for direct insulationcontact. Check your local buildingcodes for recommendations. As specified on the product packaging,follow the product instructions oninstallation and wear the proper protective gear when installing insulation.The easiest and most cost-effectiveway to insulate your home is to addinsulation in the attic. To find out if youhave enough attic insulation, measurethe thickness of insulation. If there is less5Insulation and Weatherizationsome parts of the country may requirelower R-values than the DOE recommendations, which are based on costeffectiveness. For more customized insulation recommendations, visit the U.S.Department of Energy’s insulation pageat www.eren.doe.gov/buildings/wthr insulating.html. The Zip-CodeInsulation Program can tell you the mosteconomic insulation level for your new orexisting home.Although insulation can be made froma variety of materials, it usually comes infour types—batts, rolls, loose-fill, andrigid foam boards. Each type is made tofit in a different part of your house. Battsare made to fit between the studs in yourwalls or between the joists of your ceilingsor floors. Batts are usually made of fiberglass or rock wool. Fiber glass is manufactured from sand and recycled glass,and rock wool is made from basaltic rockand recycled material from steel millwastes. Rolls or blankets are also usuallymade of fiber glass and can be laid overthe floor in the attic. Loose-fill insulation(usually made of fiber glass, rock wool, orcellulose) is blown into the attic or walls.Cellulose is usually made from recyclednewsprint treated with fire-retardantchemicals.Rigid foam boards are made of polyisocyanurate, extruded polystyrene (XPSor blueboard), expanded polystyrene(EPS or beadboard), or other materials.These boards are lightweight, providestructural support, and generally have anR-value of 4 to 7 per inch. Rigid boardinsulation is made to be used in confinedspaces such as exterior walls, basements,foundation and crawl space walls, concrete slabs, and cathedral ceilings.

New ConstructionFor new construction or home additions, R-11 to R-28 insulation is recommended for exterior walls depending onlocation (see map below). To meet thisrecommendation, most homes andadditions constructed with 2 in x 4 inwalls require a combination of wall cavityU.S. Department of Energy Recommended* Total R-Valuesfor New Construction Houses in Six Insulation Zones231122155243Insulation and Weatherization6344264*These recommendations are cost-effective levels of insulation based on the best available information on localfuel and materials costs and weather conditions. Consequently, the levels may differ from current local buildingcodes. In addition, the apparent fragmentation of the recommendations is an artifact of these data and shouldnot be considered absolute minimum requirements.602477423mYou may also need to add insulationto your crawl space. Either the walls orthe floor above the crawl space should beinsulated.than R-22 (7 inches of fiber glass or rockwool or 6 inches of cellulose) you couldprobably benefit by adding more. MostU.S. homes should have between R-22and R-49 insulation in the attic.If your attic has ample insulation andyour home still feels drafty and cold inthe winter or too warm in the summer,chances are you need to add insulationto the exterior walls as well. This is a moreexpensive measure that usually requires acontractor, but it may be worth the cost ifyou live in a very hot or cold climate.

One ofthe quickest dollar-saving tasks you cando is caulk, seal, and weatherstrip allseams, cracks, and openings to the outside. You can save 10% or more on yourenergy bill by reducing the air leaks inyour home. Don’t keep your refrigerator or freezertoo cold. Recommended temperaturesare 37 to 40 F for the fresh food compartment of the refrigerator and 5 Ffor the freezer section. If you have aseparate freezer for long-term storage,it should be kept at 0 F. To check refrigerator temperature,place an appliance thermometer in aglass of water in the center of the refrigerator. Read it after 24 hours. To checkthe freezer temperature, place a thermometer between frozen packages.Read it after 24 hours.The EnergyGuide label on new refrigerators will tell you how much electricityin kilowatt-hours (kWh) a particularmodel uses in one year. The smaller thenumber, the less energy the refrigeratoruses and the less it will cost you tooperate. In addition to the EnergyGuidelabel, don’t forget to look for theENERGY STAR label.

Caulk and seal air leaks where plumbing, ducting, or electrical wiring penetrates through exterior walls, floors,ceilings, and soffits over cabinets.

Look for dirty spots in your insulation, which often indicate holeswhere air leaks into and out ofyour house. You can seal theholes by stapling sheets of plasticover the holes and caulking theedges of the plastic. Install storm windows over singlepane windows or replace themwith double-pane windows. Stormwindows as much as double theR-value of single-pane windowsand they can help reduce drafts,water condensation, and frost formation. As a less costly and lesspermanent alternative, you can usea heavy-duty, clear plastic sheet on aframe or tape clear plastic film to theinside of your window frames duringthe cold winter months. Remember,the plastic must be sealed tightly to theframe to help reduce infiltration. When the fireplace is not in use, keepthe flue damper tightly closed.

During the heating season, keep thedraperies and shades on your southfacing windows open during the day toallow the sunlight to enter your homeand closed at night to reduce the chillyou may feel from cold windows.

Close an unoccupied room that isisolated from the rest of the house,such as in a corner, and turn downthe thermostat or turn off the heatingfor that room or zone. However, do notturn the heating off if it adversely affectsthe rest of your system. For example,if you heat your house with a heatpump, do not close the vents—closingthe vents could harm the heat pump. Select energy-efficient equipmentwhen you buy new heating and coolingequipment. Your contractor should beable to give you energy fact sheets fordifferent types, models, and designsto help you compare energy usage.Look for high Annual Fuel UtilizationEfficiency (AFUE) ratings and theSeasonal Energy Efficiency Ratio(SEER). The national minimums are78% AFUE and 10 SEER. Look for the ENERGY STAR andEnergyGuide labels. ENERGY STAR is a program of the U.S. Department ofEnergy (DOE) and the EnvironmentalProtection Agency (EPA) designedto help consumers identify energyefficient appliances and products.DuctsOne of the most important systems inyour home, though it’s hidden beneathyour feet and over your head, may bewasting a lot of your energy dollars. Yourhome’s duct system, a branching networkof tubes in the walls, floors, and ceilings,carries the air from your home’s furnaceand central air conditioner to each room.Ducts are made of sheet metal, fiberglass, or other materials.Unfortunately, many duct systemsare poorly insulated or not insulated22What’s a Btu?One Btu, or British thermal unit, isroughly equivalent to burning onekitchen match. That may not soundlike much, but a typical home consumes about 100 million Btu per year.Approximately 44% of the total isused for space heating.properly. Ducts that leak heated air intounheated spaces can add hundreds ofdollars a year to your heating and cooling bills. Insulating ducts that are inunconditioned spaces is usually verycost-effective. If you are buying a newduct system, consider one that comeswith insulation already installed.Sealing your ducts to prevent leaks iseven more important if the ducts arelocated in an unconditioned area suchas an attic or vented crawl space. If thesupply ducts are leaking, heated orcooled air can be forced out unsealedjoints and lost. In addition, unconditioned air can also be drawn into returnducts through unsealed joints. In thesummer, hot attic air can be drawn in,increasing the load on the air conditioner.In the winter, your furnace will have towork longer to keep your house comfortable. Either way, your energy losses costyou money.Although minor duct repairs are easyto accomplish, ducts in unconditionedspaces should be sealed and insulated byqualified professionals using the appropriate sealing materials. Here are a fewsimple tips to help with minor duct repairs.Duct Tips Check your ducts for air leaks. Firstlook for sections that should be joinedbut have separated and then look forobvious holes. If you use duct tape to repair and sealyour ducts, look for tape with theUnderwriters Laboratories (UL) logo11Heating and CoolingDuring the cooling season, keep thewindow coverings closed during theday to prevent solar gain.
