I am working on a project, which is going for LEED C&S. The project has tenant occupied space, which has designed HVAC system for it. I want to know if there is any provision for modelling this system. Should I go for system as per design or as per baseline model?
Kindly tell me the provision given in LEED C&S for modelling HVAC systems for tenant occupied spaces.

If the system is designed you can model it in the Proposed case. If the tenant system is not designed you model it the same as the baseline system.

The reference would be in 90.1-2007 Table G3.1-10 Proposed (a).
