Improving the Energy Efficiency of Your Historic Florida Home

  1. 1. ImprovingEnergy Efficiency in your Historic Home
  2. 2. “Efficient energy use, sometimes simply calledenergy efficiency, is the goal of efforts to reduce the amount of energy required to provide products and services.”“Making homes, vehicles, and businesses more energy efficient is seen as a largely untapped solution to addressing the problems ofpollution, global warming, energy security, and fossil fuel depletion.”
  3. 3. Why Improve Energy Efficiency? In our homes we want to:  Improve comfort  Reduce fossil fuel/ non-renewable energy use  Save money
  4. 4. The goal is to reduce energy use and improve comfort without diminishing the integrity of your historic home.And dont spend more than you would save.
  5. 5. “... when comparing buildings of equivalent size and function, building reuse almost always offers environmental savings over demolition and new construction.”
  6. 6. Understanding Your Historic Home“Early homes had many energy conserving features out of necessity because of the inefficiency of heating with fireplaces and the lack of artificial cooling. Interest in these features lessened as technical advances produced a greater ability to control interior temperatures while at the same time reducing the amount of homeowner labor. Ultimately, large mechanical systems were used to completely control the interior environment, thus eliminating the need for energy saving features.”- John Burns, Energy Conserving Features Inherent in Older Homes
  7. 7. Understanding Your Historic Home Designed to make the most of the natural environment Florida homes designed for Florida climate  High ceilings  Wide eaves  Porches  Raised foundations  Lots of large, operable windows with screens  Natural Light  Cross ventilation Air conditioning was not anticipated
  8. 8. Approaches to Improving Energy Efficiency1.Reduce reliance on energy sources/ improve performance of existing systems2.Upgrade to more efficient systems3.Replace existing energy sources with renewable energy sources
  9. 9. Simple Ways to Reduce Reliance on Energy Sources Adapt your attitude about comfort  Accept a wider range of temperatures Take an active role in regulatingclimate  Open windows rather than turning on AC  Use blinds/ curtains to reduce heat gain  Use ceiling fans before resorting to ACBECOME PART OF THE CLIMATE CONTROL SYSTEM
  10. 10. Simple Ways to Reduce Reliance on Energy SourcesReduce Heat Gain Use blinds and heavy curtains UV blocking films Awnings/ shutters Plant trees Add a porch
  11. 11. Simple Ways to Reduce Reliance on Energy Sources Seal wall openings  Plumbing, AC, wire penetrations, dryer vent, outlets, fireplace Weatherstripping Install a solar-powered attic fan Replace lights bulbs with more energy efficient bulbs Insulate your hot water heater Air dry clothes
  12. 12. Upgrades that will Improve Energy EfficiencyUpgrade appliances Water heater  Solar  Tankless/on demand  Set on a timer Kitchen Appliances  Energy Star ratings Water saving fixtures
  13. 13. Upgrades to Reduce Reliance on Energy SourcesInsulation  Attic  Radiant barrier  Floor  Walls − “One of the top reasons for exterior paint failure, termites and structural damage to old houses is loose cellulose or fiberglass insulation blown into the sidewalls”
  14. 14. Upgrades to Reduce Reliance on Energy SourcesRoofing Light Roof Colors  Cool Roof Colors  Metal roof  20% reduction in energy costs No skylights – use dormers when more light is desired
  15. 15. Upgrades to Reduce Reliance on Energy SourcesWindows Windows contribute only 10-12% of overall infiltration to the building envelope. Much more infiltration occurs at roof eaves, foundations and even through wall receptacles, dryer and plumbing vents and fireplaces. Double-pane windows do not work well at reducing heat gain
  16. 16. Upgrades to Reduce Reliance on Energy SourcesReplacement Windows – Rarely worth theinvestment 20 year max. life Generally a for replacement windows It takes 40+ years to recoup the cost of the replacement windows through energy savings Studies have demonstrated that a historic wood window, properly maintained, weather- stripped and with a storm window, can be just as energy efficient as a new window
  17. 17. Upgrades to Reduce Reliance on Energy SourcesWindows Keep windows in good repair Close latches so they meet properly Weatherstripping UV films
  18. 18. Upgrades to Reduce Reliance on Energy SourcesAir Conditioning Min. SEER Rating 13  If unit is more than 12 years old, replacing it with more efficient model could cut your cooling costs by 30% Size properly – bigger is not better Ducts in conditioned space if possible Air handler should not be in attic
  19. 19. Upgrades to Reduce Reliance on Energy SourcesAir Conditioning Seal duct leaks or replace ducts (insulated) Get a programmable thermostat Change filters monthly Small duct high velocity systems
  20. 20. Replacement Energy SourcesSolar Place panels on non-primary facades Place panels on outbuildings Solar producing shinglesWind Turbines Aesthetics/ Size Removable Noise
