Achieve increasing levels of energy conservation beyond the prerequisite standard to reduce environmental impacts associated with excessive energy use.
Projects are required to achieve two (2) Optimize Energy Performance points. Project teams are awarded these two points towards LEED certification but documentation that verifies compliance with two (2) Optimize Energy Performance points is mandatory for a project to be awarded LEED certification.
Demonstrate a 15% improvement in the proposed building envelope compared with the base line building performance rating per ASHRAE/IESNA Standard 90.1 2004 (without amendments) for the building envelope components such as glazing, insulation, roofing, and slab.
Option 2 – Prescriptive compliance path
