1. Home energy audit 3rd project meeting, Sulingen 07.09.2009 Presenters: Emese Sulán Marcell Magyar Batthyány LajosGrammar School andSecondaryMedical School www.eltandict.com/course

2. Content Why study energy use Suggestions for energy conservation Energy assessment Energy audit Energy hogs 1 2 3 4 5

3. Whystudyenergyuse? • Large-scale environmental effects • Individual/ personal responsibility • Substantial financial savings possible Source: International Energy Agency (IEA)

4. Why an Energy Audit? • Identify where energy is going • Identify savings opportunities • Part of a comprehensive environmental program

5. Energyconservation Definition: Energy conservation is the practice of decreasing the quantity of energy used. It may be achieved through efficient energy use, in which case energy use is decreased while achieving a similar outcome, or by reduced consumption of energy services.

6. Energy audit process Analyze Information Data Energy audit Take action Measure

7. EnergyAssessment Spreadsheet • Provided a complete break-up and summaries of the total annual energy consumption and cost. • Helped identify avenues for energy and cost savings. • Included separate sections for the major areas of energy consumption at our homes.

12. Energyefficiency Efficient use of energy to obtain desired outputs that involves using alternative technologies that consume lower energy for the same purpose.

13. Suggestions • Turn down the temperature of your water heater to the warm setting (48,8 C%). • Check if your water heater has an insulating blanket. • Start using energy-saving settings on refrigerators, dishwashers, washing machines, and clothes dryers. • Survey your incandescent lights for opportunities to replace them with compact fluorescents. • Turn down the thermostat, or up in summer. • Clean or replace furnace, air-conditioner, and heat-pump filters.

14. Improving a homes air tightness (that is, to cut air leakage) can reduce consumption by 15-40% … proper insulation is a must! • Programmable thermostat is a must • Microwave oven’s use up to 75% less • Laptop computers use 90% less • Switch off the gadgets you don’t use!

15. Changethelightbulbs! • Because fewer watts used thus less long term cost. • It is easy to swap „normal light bulbs”, incandescent bulbs to CF bulbs (Compact fluorescent bulbs) as they are very interchangeable. • Typical reduction of wattage use is a 60 watt incandescent being replaced with an 11 watt compact fluorescent bulb.

16. Little hardertodo • Pay attention to insulation. Insulation saves in the winter and summer. • Insulate hot water pipes and ducts wherever they run through unheated areas. Install heat traps. • Seal up the largest air leaks in your house. It’s usually the cut troughs. • Install a clock thermostat to set your thermostat back automatically at night.
