This prerequisite establishes the project’s energy performance so that the project can demonstrate a commitment to energy efficiency. The energy use of a LEED-CI project, in terms of the ASHRAE 90.1–2007 standard, must meet four distinct requirements:
- ASHRAE 90.1-2007 – Mandatory Requirements
- ASHRAE 90.1-2007 – Prescriptive Option or Performance Option
- Lighting Power Density Reduction of 10%
- Energy Star-labeled Equipment and Appliances - 50%
