service energy

In general you should not lump all of the "service" (also called non-regulated or process energy) uses into a single category. The LEED reviewer will want to see that all building components have been modeled and that the energy use for them is reasonable. Also it is not the intention of the 25% rule for you to simply get your model to 25%. Model the building, including all energy uses, as accurately as you can. If you are at 25% process or more do nothing. If you are under simply explain why. Usually the best way to do so is to provide a narrative or spreadhseet showing the process energy loads and the modeling assumption used for those loads.

Is it compulsory to consider process loads as 25% of the total energy cost? If the building process load is less than 25%, can we consider that value instead of default 25%?
