122. The Ice-Stick pipes condense water vapor from the air, causing the refrigerant to warm and evaporate. As the evaporated gas moves to the compressor, pressurization raises its temperature. A pump sends the accumulated heat through the buildings water system. As the heat is dispersed the pressure falls, and the refrigerant travels back to the evaporator to repeat the cycle.

In July 2009, almost 50% of new homes were sold with a green certification. Over 50%, and appraisers will need to discount a home that is not green, since green will have become the new market norm.
