Page 2

G|PROLEED Gold Building, NY

A green building is designed, constructed and maintained to minimize adverse environmental impacts and to reduce energy consumption, while contributing to the health and productivity of its occupants.  

A key component is consideration of the building's impacts and performance over its entire life.
