<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>There is no way to exclude process energy from EAp2/EAc1 calculations
under LEED 2009. The only way you can improve EAc1 performance is to document
process savings relative to some baseline. I’m also eagerly
awaiting some assistance from the USGBC/CaGBC/ASHRAE on baselines, but I’m
not aware that anything’s been published yet. <o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>In the case of data centre energy, I thought about using Energy
Star Portfolio Manager to determine a baseline by entering a portion of the modelled
building as a data centre (less than 10% of area), but I suspect that Portfolio
Manager, being a bit of a black box, won’t spit out a separate energy
intensity for just the data centre space. I think other modelers
speaking on this issue have mentioned being lucky enough to have clients with large
data sets of previous projects that they used for benchmarking various process
loads.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>It may seem unfortunate that, for the moment, high-process
energy buildings have a difficult time getting higher energy savings compared
to their low-process load counterparts, but if the goal is to reduce building-related
GHGs (as it should be), then it’s probably about time all energy use in
buildings gets addressed. Not that good intentions help modelers much for
the time being without some baseline values we can use.<o:p></o:p></span></p>

high process energy use (60%) because of a large data center and the TV Studio
equipment, lighting, and broadcasting. The process loads stay the same in
the building for the proposed and baseline case, so the difference in energy
costs between the two (as a percentage) is very low. Whereas, if the data
center energy, broadcasting energy, studio lighting energy weren't included in
the costs for the energy usage in the building, the difference would be
greater, thus reporting just the difference in energy usage for the mechanical
system and building efficiencies.<o:p></o:p></span></p>
