When Building Energy Models Outperform Their Buildings: What Happens and How to Prevent It
Energy models have become a commonly used service for several new construction and existing renovation projects. The accuracy of energy models has improved greatly over the past decade and they have the potential to provide important information about utility consumption and costs on the design of a building. So, why do the buildings sometimes not operate as predicted? Even after one year of operation, the building performance can drop off rapidly over the next few years. Building owners who paid for the energy modeling service to help make design decisions want to see the anticipated payback. This article will investigate several causes that have the potential to alter the energy model results throughout design, construction, and facility operation. Possible solutions to these issues will also be discussed.
