Dear all,
We have a project targeting LEED BD+C: Core & Shell. My question is how to model whole-building energy simulation? Do we need to take into account the energy consumption of tenant spaces? We currently don't have information for lighting at tenant areas.
Thank you for your time and support

You must follow appendix G (table 3.1) of ASHRAE 90.1-2010, it mentions how to model the whole building including core and tenants spaces, for HVAC equipment, lighting system, etc.
For instance, if you currently don't have information for lighting at tenant areas (as usual at C&S projects), table G3.1-6c says: "Where lighting neither exists nor is specified, lighting power shall be determined in accordance with the Building Area Method for the appropriate building type.", therefore for tenant areas, set Lighting Power Densities according to Table 9.5.1 for Baseline and Proposed models.
