Many local incentive programs offer rebates for efficiency measures. Identify any available incentives at this time to inform your design decisions for equipment selection. Also look for incentives for energy optimization during the design process, like utility-funded energy modeling programs. (See Resources for help finding incentives.)
Having the owner take an active role in developing and maintaining energy efficiency goals for the project can be helpful to the project team. Stating goals in terms of a “minimum acceptable level” and a “specified payback period” is an effective way to articulate goals. For example: “Our goal is a minimum 30% reduction in lighting and HVAC energy usage” or “to implement efficiency measures with paybacks of less than 5 years.”
The owner and project team should determine the project’s energy efficiency goals and include them as part of the owner’s project requirements (OPR) and Basis of Design.
LEED-CI energy systems relate to only those building systems within the construction or remodeling scope of the project. They do not address base building systems outside the interior fit-out.
Identify the elements of the projectthat fall under this prerequisite: space cooling, space heating, lighting, ventilation, pumping, and domestic hot water. Do this by reviewing the requirements in ASHRAE 90.1-2007 and developing a building systems narrative for equipment and lighting.
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%
