New American Home 2011

  • Description: The most noteworthy features of TNAH 2011 include the airtightness of its thermal shell and the use of solar energy for space conditioning and hot water. Under blower door testing, the thermal shell achieves 0.80 air changes at 50 Pa, an amount that is considered very airtight. Open-cell spray foam insulation is used on the inside of walls and underside of the roof deck, as well as around any penetrations, to prevent air leakage.

The home uses solar energy to power its space conditioning and hot water systems. Four dedicated photovoltaic (PV) panels harness the sun's energy to power the space conditioning system. When the system is not running, other electrical devices in the home can use the solar power instead. Overall, the home uses approximately 77% less energy for heating and 83% less energy for cooling when compared to a similar home in the same climate zone. In addition, a solar thermal system, which includes an 80-gallon storage tank, heats water for a majority of the home. End Type: No Submitted: No Approved: No Modified: 2011-01-06 * Visit: No
