Dear all, Hi. For LEED NC certification, I’m modeling a building with 03 floors and less than 14.000 m² conditioned floor area. The proposed cooling system is composed by absorption chillers with natural gas as fuel. The building has no heating system, only cooling. According to ASHRAE 90.1-2007 – app. G, I understand that the baseline system is system #6. My doubt is: For cooling, Proposed model will use natural gas as fuel, and baseline will use electricity. Is that right? Because there’s a big difference between the natural gas and electricity tariffs, and I’m not sure if I can compare these costs, or if I should somehow calculate the cooling system from baseline with the natural gas tariff too. Tks in advance Thais

That is correct. Proposed is gas and baseline is electric using the appropriate rates.
