Appendix 2: core and shell energy modeling guidelines

These guidelines are intended to ensure that projects in different markets approach the energy modeling requirements in a similar manner, and to establish a minimum benchmark for energy optimization. The energy modeling is based on the ANSI/ASHRAE/IESNA 90.1–2007 Building Performance Rating Method. This can be used for developing a whole building model when the core and shell work is known but the tenant space development is unknown.
