Geo-Thermal

• Decrease hot water energy consumption
• Proven technology (70 savings)
• Most efficient heating cooling for this
  geographic area
• No greenhouse gas emissions environmentally
  friendly
• Creates 5 units of energy for every one unit of
  electricity
• No noisy outdoor condensor units
• - - - - - - - - -
• Initial investment
• Requires land area for loop (min. ½ acre for
  ground loop).
• More expensive alternative is a vertical loop
  system (wells) for smaller lots.

Windows Orientation

• Use of abundant windows skylights can increase
  passive solar radiant heating during the day
• Home orientation to maximize thermal gain
• Todays windows are thermally insulated (U-value
  coefficient). The reciprocal of R-Value. The
  lower the number, the greater the heat transfer
  resistance (insulating) characteristics of the
  material.
• Low E glass works by reflecting heat back to its
  source. It does this by utilizing an ultra thin
  metallic coating on or in the glass.

Housewrap (Tyvek / Typar )

• Combats water, moisture and air infiltration
• Prohibits growth of mold mildew
• Makes more comfortable and energy-efficient home

6
Foam Insulation

• Adds structural strength to wall areas
• Prevents sound transmission
• Prevents air permeation by up to 85 and improves
  building energy efficiency by up to 40
• Allows mechanical heating and cooling systems to
  be downsized
• - - - - - - - - - - -
• can make the home too airtight (heat to air
  exchanger)
• cost 5-6K typical 2-story home

Water Efficiency

• On Demand hot water heaters
• Insulate main hot water distribution lines
• Hot water delivery with timer controlled
  recirculation system
• Dual flush toilets (save .5 gpf)
• Collect use rainwater as permitted by local
  code
• Weather based irrigation controllers
• ENERGY STAR water conserving appliances
  (dishwasher, front load washing machine)

Construction Waste Recycling
12
Miscellaneous

• Use covered entry (porch / awning) at exterior
  doors to prevent water intrusion and subsequent
  rotting of joists, sills and finish
• Disassemble existing buildings (vs. demolishing)
  re-use salvaged materials
• Use of on-site bins for sorting scrap re-use
• C D waste management plan
• Conduct on-site recycling
