Hi,
In one of the projects, there are no cooling tower. There are no AC Spaces in our project, and hence for the energy simulations ASHRAE 90.1 2010 Appendix G Space System 10 is selected. This is not congruent with the Pilot Credit requirements which states that the project baseline system designated for the building is using ASHRAE 90.1-2010 Appendix G Table G3.1.1 and includes a cooling tower (systems 7 & 8). But since there are no AC Spaces and no Cooling Tower in the project, System 10 was selected.
Kindly clarify whether which system to be selected.
- the baseline system designated for the building using ASHRAE 90.1-2010 Appendix G Table G3.1.1 includes a cooling tower (systems 7 & 8)
- the project design case does not include a cooling tower
- the design case mechanical system does not use the latent heat of the evaporative cooling of water.
- the project does not receive any cooling from a District cooling system
All other system types are ineligible for credit. The USGBC guideline clearly states that no other way is eligible for this pilot credit. The best approach may be to directly contact GBCI and explain your special circumstances. And provide email confirmation (if approved) for LEED submittals. Hope it helps!
