Dear all,
Can someone please advise on what are the conditions to claim an exceptional calculation for process energy, for having the proposed process energy less than the baseline's?
For example, we're working on one project whereby the design team is planning on installing highly efficient elevators. Is this something we can take advantage to?
Thanks!

Yes you can.
You will need to provide a narrative and calculations. The narrative must justify the chosen baseline for your location (i.e. what is standard practice for elevators in similar buildings in your area?).

Thanks Marcus. In that narrative, do you need to actually reference an SBD/Case Report for that local standard or can you claim it based on first-cost models available? What is common and typical in claiming a "baseline"? I'm not an engineer so forgive my ignorance.
We have a similar question for project regarding the high-speed roll-up doors and in-folding dock levelers we are using to minimize air infiltration heat loss in a cold storage facility. Our problem is we can't find a cold storage industry "baseline standard" for these features. But can we demonstrate the energy efficiency based on common, first-cost alternates and use straight-up calculation in the narrative to estimate the comparative savings?

Referencing a local standard can help. It is up to you to tell the reviewer what you believe is the local standard. The more data or information you can use to back it up the better.
Basically what is standard industry practice in your area for the installation you are wanting to claim savings for against the baseline? For example, are strip curtains typical practice in your application instead of high speed doors? The lowest first cost alternative in this case could be nothing installed in the opening which may or may not be an appropriate baseline. You need to make the case for the baseline you use. If the lowest first cost alternative is standard practice then it can be the baseline.
