1. Review the LEED v4 Building and Construction minimum program requirements. requirements. List the requirements below and determine if the ffordable ffordable !ome "ro#ect complies with the minimum program requirements. It needs to be fixed on permanent location with a minimum area of 1000 sq. feet. $. Determine the rating s%stem that should b e used for design and construction of the ffordable !ome "ro#ect. The rating system includes innovation and design process, location, sustainability, water efficiency, energy and atmosphere, materials and resources, indoor quality,and awareness and education. &. Because larger homes consume more energ% and produce more greenhouse gas emissions' LEED v4 credits provide a !ome (i)e d#ustment to reward more compact living spaces. *he ad#ustment is provided in the Energ% and tmosphere credit categor%. *he pro#ect can earn one point for ever% 4+ decrease in conditioned floor area compared with the E,ER- (*R (*R for !omes' version &' reference home as shown in the table below. a.
