  • EPA calculates the amount of salvageable structural lumber disposed of annually 1 Billion board feet of structural lumber 3-5 pounds per square foot $250-$1000 plus disposal cost 62,000 average American homes could be built from itOver 1 Billion people without access to waterAbundance mentality – grow the pot not get more from it.Locally we have a lot of discussion on maintaining green space – local planning ordinances actually waste more green space and promote sprawl

    Reduced Energy usage and Water usage
    Healthy
    Protect occupant health and increase productivity
    Minimize waste
    Designed and constructed in a manner that minimizes waste, pollution, and environmental degradation
  • Impact of Buildings in U.S.A.
    In the United States alone, buildings account for: •    72% of electricity consumption,•    39% of energy use,•    38% of all carbon dioxide (CO2) emissions,•    40% of raw materials use,•    30% of waste output (136 million tons annually), •    14% of potable water consumption.

  • Energy Efficiency – The Basics
    How much energy will a home require to operate
    Based on the International Code Commission’s International Energy Construction Code (ICC IECC)
    Don’t be afraid to ask pros what the jargon means
    Department of the Energy has very good tools available
    NWI Green Building Alliance
  • What your energy is used for:
