In addition to the standard visit from the city inspector’s office, each +Plus House is scrutinized by a team of licensed inspectors from the US Green Building Council throughout the home’s design and construction. The inspectors help us to design the +Plus Houses for maximum health and energy efficiency and assign us points for meeting our targets. At the end of the construction process these points add up to a LEED score. All +Plus Houses are intended to achieve LEED certification, with our first three having achieved LEED Gold and Silver. We also aim to earn a HERS energy efficiency score that beats 95% of Chicago area homes.
