University of Toledo's participation in the Phase II of USGBC's Research to Practice Program was a catalyst in developing EEAST and improving its calculations for the green construction community. As part of this work, we have added to EEAST a section that calculates possible LEED credits that can be earned using the technologies modeled in EEAST. EEAST now performs calculations to determine how many of LEED's Sustainable Sites (SS) and Water Efficiency (WE) credits can be obtained for a specific building that may be built with standard versus high efficiency toilets, or by using rainwater versus municipal water in toilets and in irrigation.
