Use the ASHRAE compliance forms to update the status of your prerequisite compliance. Typical prescriptive requirements may include a certain heat-pump efficiency rating and the installation of economizers. Building owners may perceive these to be high-cost items, so keep the owner involved in your prescriptive requirement review.

Complying with the prescriptive method may require some additional time on the part of the design team to review and update compliance with each requirement. The mechanical engineer, architect, and lighting designer need to walk through the checklist to t
