[Bldg-sim] LEED Process Energy Reduction

[Mark Prince]

Jeremy,

Did you file a CIR and get approval from USGBC before pursuing this, or did you just assume USGBC would accept your logic?  From where I was raised, modifying process loads is forbidden territory.  I'm thinking it would be best to get CIR approval first.

Glad this worked out for you though.

We have documented this on two projects - in both cases we had to document what the industry standard for the process would be and then how ours was more efficient.  One was related to conveyor energy usage and the process integrator documented the expected savings based on numerous other installations they had done over the past few years.  The second one was the process energy associated with refrigeration - through team member networking we surveyed approximately 200 owners of buildings of a similar scope and use to document the baseline refrigeration system that a building of that type would use.  Then we documented how our system was different and more efficient.

In both cases this was approached with the alternative calculation methodology of ASHRAE 90.1 and that section of the LEED template.  Hope that helps!

Hello All,

I am currently working on several process intensive buildings. The mechanical systems and corresponding control strategies that are being designed are ideal for achieving 30%-40% savings in a standard office building but I'm afraid that the common denominator, the high process loads, will significantly reduce my projects savings. Has anyone successfully submitted for a reduction in process load. If so, what/how did you document the reduction?

Thanks for your time.
