What's an energy audit?

While ASHRAE identifies four levels of energy audits, level 0 and level 1 audits are the most popular. They simply require comparison with benchmarked consumption rates at other similar facilities, or conducting a facility walk-through to visually identify energy savings opportunities. Common tactics include identifying and optimizing the largest loads in the facility. The most obvious of these loads is lighting. Since many utilities offer rebates for lighting upgrades, the cost is often low and the payback time short.
