The Building Energy Modeling (BEM) Library demonstration website was created to advance the use of building simulation modeling in efficiency projects. It provides information resources for three audiences - Owners & Managers, Practitioners, and Financiers. For Owners & Managers, the BEM Library provides information to support defining and procuring modeling services for commercial new construction, renovation, or operation improvement projects. Guidelines and examples outline the value of modeling, types of services, and an example solicitation. For Practitioners, the BEM Library aims to improve standardization, expedite modeler training and expand the building energy modeling workforce. The industry needs to have modeling best-practice methods defined, documented and made readily available.
