ASHRAE Level I, II & III Energy Audits

A structured evaluation of how a building uses energy and where it can use less, performed at one of three levels of effort defined by ASHRAE. Level I combines a review of available energy information with a walk-through to establish direction. Level II adds a detailed survey and analysis of systems, operating conditions, measures, costs and projected effects. Level III takes selected measures through the detailed engineering evaluation a major investment decision requires. Each level builds on the one before it, so you can start at Level I and go deeper only on the measures that justify it.

The decision in front of you, the records available and the complexity of the proposed improvements determine the right scope. A larger building does not automatically require the highest level, and a smaller building with one large investment question may need Level III analysis on that measure alone.

Yes. We tailor the assessment to building use, systems, access, occupant needs and the scope you authorize, whether the building is an apartment community, a school, a clinic or a manufacturing facility.

No. An audit evaluates projected opportunities. Post-improvement measurement and verification requires a defined baseline and a separate verification approach, which we can design alongside the audit if you want to track results.

Yes. It establishes system conditions and evaluates efficiency and electrification opportunities. A strategic decarbonization engagement adds emissions assumptions, capital sequencing and implementation tracking beyond the audit's defined scope.

Utility records, operating schedules, equipment information, prior studies and access to key spaces all help. We settle the audit level, the buildings and the site conditions with you before assigning the engineering effort, so no one pays for analysis the decision does not need.
