Description / Abstract:

Overview

A commercial building energy analysis can generally be classified into the following three levels of effort:

• Level 1—Walk-Through Analysis

• Level 2—Energy Survey Analysis

• Level 3—Detailed Analysis of Capital Intensive Modifications

In addition, there is a Preliminary Energy-Use Analysis (PEA), which is a prerequisite for any audit, and there are targeted audits, which do not have a strictly defined level of effort bu t may be useful or necessary for some situations.

This section contains a brief overview of the PEA, each audit level, and targeted audits. More rigorous definitions for each level also follow in this section.
