Walk-Through Audit (WTA): as the name suggests, this audit consists of a walk-through inspection of a facility to identify maintenance, operational or deficient equipment issues and also to identify areas that need further evaluation.

The results of a Walk-Through Audit include an identification of energy saving opportunities, a qualitative analysis of the implementation of energy saving measures and an estimation of its potential energy saving. The final audit report is usually accompanied by basic comments on a project’s feasibility.
