Hello Marcus.

We have a project that will be applying for LEED certification under CI. The project is located on 4th floor within an office building with 5-floors. The building is served by a common HVAC system (air cooled chillers, and pumps), everything else will be in the design as part of the tenant development (interior HVAC, lighting etc).

For the Proposed Design the simulation strategy is to simulated only the CI portion of the building by spliting the Chiller capacity for the CI project area. COP wil be simulated with chiller nominal value. Other systems such as pumps will be sized for the CI load.

For the Budget design the simulation will be based on ASHRAE chapter 11 for the CI portion of the building as well.

Do you think this approach is valid for the GBCI reviewers?

Any advise would be appreciated.
