[Bldg-sim] Process Energy Cost

[Hernandez, Arturo]

There is a lot of misconception with 25%  process energy. Your building
should be modeled as is if it over 25% of total energy, great you met
the threshold. If it is under 25% you should submit an explanation
describing your process load assumptions. Therefore you should ALWAYS
submit your actual loads.

Hello All,

 

The following excerpt is from LEED v2.2 "The default process energy cost
is 25% of the total energy cost for the baseline building. For buildings
where the process energy cost is less than 25% of the baseline building
energy cost, the LEED submittal must include supporting documentation
substantiating that process energy inputs are appropriate." This clearly
defines the minimum process energy cost but does it allow one to reduce
the energy cost to 25% for a building like a data center that would have
a much higher cost?

 

Thanks
