The answer—energy modeling payback is typically 1 or 2 months!—is surprising at first. But it shouldn''t be. For large buildings, modeling costs run from $30,000 to $200,000 depending on the ECMs considered and the tools required to evaluate them. Even the high side of that figure is a fraction of the annual energy costs of a typical large
