Campus Thermal Energy Plant Submission

Hi. We have LEED Campus Development with 2 LEED projects inside. Let's call it "Development F" and "Development A". Development F is housing the thermal energy plant, hence exception for option 2 is applicable. We have run simulation on both option and the savings are not eligible for both options. Under opt. 1: Development F achieves 6% and Development A achieves 9% Under opt. 2: Development F achieves 18% and Development A achieves 20% How we should address this situation? Since we can't fit at both options

I am not sure I understand the problem that is preventing the fit you are referencing? Point cap/point floor? 18% minimum? Could you be a bit more specific. Keep in mind you are not required to use the DESv2. You can use 90.1-2007 with addendum ai instead.

Hi Marcus. Under opt.1: we still required to meet 10% minimum savings. Hence it is not possible. Under opt. 2: we required to meet point floor of 6. Since our development is NC. Hence we required to meet 22%. Is my understanding correct? If we can use 90.1-2007 directly, how we should declare the energy consumption of campus thermal energy on each development? By their ratio of building cooling load?

Got it. You are in an awkward spot. Using addendum ai will probably not help enough to get you over 10%. You could ask GBCI to grant you an exception to the point floor. I am not sure how that would be received. You could ask them if you could earn the prerequisite without any points under Option 2. The obvious answer would be to improve the energy efficiency of the projects to increase the percent savings.

Thanks Marcus. Yes, we have tried to clarify with GBCI on this situation.
