The award was announced July 21, 2011 by the United States Green Building Council (USGBC).
This house is one of only approximately 400 custom homes constructed worldwide that have won the LEED Platinum designation, according to the USGBC, the originating and administrative body of the LEED program. Leadership in Energy and Environmental Design, or LEED, provides the construction industry with a definition of green building design and a means to measure green construction techniques and their effectiveness. As part of this program, the USGBC created a rating system to promote sustainable building practices. Since LEED’s inception in 1998, 993 house projects of all types, totaling 3,365 homes worldwide, have received a Platinum award.
A house can earn a maximum of 136 points. A structure the size of this house requires 80 points to obtain the highest award, a Platinum. This Praxis-designed house won 88 points.
The house also has achieved an Energy Star rating, as well as an Indoor airPlus certification. The latter designation is an EPA-sponsored program designed to encourage the construction of homes with improved interior air quality. It addresses issues such as moisture control, radon control, pest management, improved heating and air conditioning technology, improved combustion venting and reductions in chemical content of building materials.
The house has a Home Energy Rating System score of 58. The HERS Index compares the average house built in 2006, which receives a score 100, with a house that uses zero energy. The lower the score, the better the rating. A score of 58 means the Rothstein/Meckler house is 42% more efficient than the hypothetical 2006 home. (As a point of reference, a house must score 85 or below to qualify as an Energy Star structure, only 15% more efficient the 2006 house.)
