Hi Guys, I am a energy simulation engineer. Now I have a project which uses the district steam supplied by the local government as heat source. I did the energy modeling based on the guideline "Treatment of District or Campus Thermal Energy in LEED V2 and LEED 2009 – Design & Construction" option 1. When I set the energy rate in the modeling, I meet some problems. From this guideline page 13 to 14, it seems that there is a formula to calculated the steam rate. My question is that does it forcibly to use this formula to calculate the energy rate? Can we use the local energy rate instead?

You are required to use the formula if the rate is not flat and you are applying DESv2 Option 1. You can use the local rate if it is flat under the DESv2 Option 1 or if you alternatively use Addendum ai from 90.1.
