A good energy audit is a valuable owner’s guide to making the best energy efficiency investment decisions. When the best energy conservation measures (ECMs) are identified and implemented, the facility owner will make the smartest choices, and receive the greatest return on investment.When the best ECMs are not identified and implemented, then the opportunity for reducing utility costs has been squandered, and the facility owner suffers financially as a result.Traditionally, developing energy audits involved hiring professionals to identify and communicate the ECMs.Typically, the more seasoned and skilled the energy auditor, the better the energy audit.
With the ever-increasing power of computers and abundance of energy use data, new software and services are now available that provide some impressive analysis of buildings.One of these new services, virtual audits, offer inexpensive energy audits, attractive web graphics and the capability to provide rapid analysis of buildings without an energy auditor having to set foot on site.
This presentation discusses whether the efficacy of virtual audits are supported by the results.The main claim is that a virtual audit can produce an actionable energy audit without having an energy auditor set foot on site.This presentation evaluates this potentially overreaching claim by considering the differences between traditional and virtual audits.
