[Add new paragraph just before 3rd paragraph that starts "Project teams may..."]"In 2009, the EPA released the Indoor airPLUS program as a replacement for its original Indoor Air Package program. LEED for Homes projects that register after June 23, 2009 must use the Indoor airPLUS program to earn EQ 1; projects that registered prior to that date are encouraged to use Indoor airPLUS, but they may use Indoor Air Package instead."
