Hello. I am working on a Shell and Core submission. The tenant requirement specifies a VRF system with an EER=3.45 for the proposed building. I am concerned that this is not enough information to qualify as a ‘HVAC system design’ according to Table G3.1.10. option 'b'. Can someone give me an idea of what minimum design detail is needed to follow this route?
For example, would a full example-design, with equipment selection for a typical floor be adequate to apply to the whole proppsed buidling model?
The alternative is to model the baseline building HVAC system (Table G3.1.10.d). We are trying to avoid this since the VRF system will probably be notably more efficient.
Thanks for helping.
