Since the launch of various energy codes, energy engineers have compared their proposed energy model to a baseline energy model via a “percent better than code” metric. Whether this metric is a percent energy savings or percent energy cost savings output, what significance does this value have outside of the realm of the specific code or standard under which the model was analyzed?
