    1. Garry Ruliffson Energy Solution SpecialistOPPD Welcome To:Residential Energy Efficiency

    2. Understanding a Home as a System The Energy Efficient Home

    3. Energy Trends

    4. Energy Efficiency in the Home

    5. Diagnosing a Home

    6. Performance Test

    7. Performance Test • Infrared Imaging

    8. Typically, What is the first options we choose for making homes more Energy Efficient? 1. Windows Long term Payback So, Where Do We Start? 1 or 2.High Efficient Heating 1, 2, or 3. Add Insulation High Efficient Fossil Fuel High Efficient Heat Pumps

    9. The Air Barrier

    10. Wind & Stack Effect Pressure Wind Stack Effect

    11. Mechanical Infiltration • Exhaust 50 to 110 CFM • Exhaust up to 150 CFM • Exhaust 200 to 230 CFM

    12. The Air Barrier Exterior Wind Air Barrier Interior Air Barrier

    13. Stack Effect Pressure

    14. The Thermal Barrier

    15. The Thermal Barrier

    16. Typical Basements are Energy Wasters An energy assessment of your home’s Basement Insulation • Uninsulated basements can make up almost 40% of your homes heating load requirements • Adding minimum insulation (R-10) cuts basement heating loads in half

    17. Basement Wall Insulation • Extruded Foams

    18. Wall Insulation Types • Blow-In Insulation Systems • Typical Installation • Spray Foam

    19. Attic Insulation Types • Loose-Fill • Cellulose

    20. Indoor Air Quality

    21. Ventilating Homes for PEOPLE Air-Cycler Pulling in Straight Unconditioned Air Energy Recovery Ventilator (ERV)

    22. Heating & Cooling Ductwork

    23. Ductwork - AtticOutside Conditioned Space • Furnace off • Furnace on • Red is Bad – hot air leaking out

    24. Heating & Cooling Systems

    25. Fossil Fuel Furnace Efficiencies AFUE 60% - 80% - 90% - 97%

    26. How a Heat Pump Works

    27. Putting it all together

    28. The Home System

    29. In the Future, There Will Be a Demand for High Performance Homes!
