A project consists of the renovation of 8 floors of an existing building intended for multi-tenant mixed office and retail use. The building qualifies as a historic building. The project is registered under the LEED Core and Shell (CS) rating system. The floor plan layouts have been designed in such a way that essentially all Core areas have been eliminated (Core and Tenant areas being defined thru the LEED CS v2.0 guidelines). The only owner-operated equipment is portions of a common ventilation system serving select floor areas. All remaining floor areas, entranceways, perimeter areas, and elevator lobbies will be served by equipment operated by the Tenants. Our intent is to only model the energy consumption used by the Proposed owner-operated ventilation system and compare that to a Baseline ventilation system created thru ASHRAE\'s Performance Rating Guidelines. Is this acceptable?
The applicant is requesting confirmation about the modeling protocol for the project; however, not enough information has been provided to understand the unique aspects of the project. As a general rule, the applicant must model all buildings to meet all the requirements of ASHRAE 90.1-2004, Performance Rating Method, LEED-CSv2.0 EA Credit 1 requirements and LEED-CS v2.0 Appendix 2 - Core and Shell Energy Modeling protocol. For items out of owner\'s control, the parameters for the proposed and the baseline models must be maintained as identical. Applicable Internationally.
