Our project involves the new construction of a healthcare clinic that is being heated and cooled via heating and chilled water produced by a campus central plant. We are modeling the design using Carrier's HAP. We have decided to pursue Performance Option 1 (streamlined path) from the "Treatment of District or Campus Thermal Energy in LEED 2009" publication which allows the modeling of campus thermal energy as purchased energy for both baseline and proposed case with no direct accounting of the campus's network's efficiency.

I assume that on the EAp2-7 spreadsheet, under 1.4.3 HVAC water side, after selecting yes for district heating/cooling, I can leave all the inputs blank regarding chillers, chw pumps, cooling towers, boilers, etc. since all that equipment is "upstream" of the building. Is this correct?

If so, shall I include a narrative explaining this, or can I fill out the first cell on the spreadsheet and describe that we are following Performance Option 1?

Thanks for any assistance or advise.
