[Bldg-sim] Leed eac1 Plug loads

[Fred Betz]

Chris,

The plug loads are the plug loads. The 25% is just a guidance value from USGBC/GBCI. I've been over and under this level numerous times without a problem.

If you've used the load estimated by the mechanical and/or electrical engineers and apply an appropriate schedule then it should be good enough.

When you're under the 25% threshold a text box will appear for you to explain why. Just state that you've modeled the plug loads as designed.

10 W/m2 sounds a little low for an office. If the owner has made a commitment to use Energy Star devices or laptops for everyone, then 10 W/m2 is plausible. Don't forget to include other equipment like servers/IT equipment, copiers and kitchen equipment (microwave, coffee maker, etc.)

Dear bldg sim'rs

I'm a little concerned that the plug loads I've modelled in my offices are low and could leed to some unwanted usgbc comments.

I'm meeting the 25% requirement but the peak load in the offices is 10w/m2. Whilst i dont think this is overly optimistic the reviewers may think otherwise. Has anybody had experience of plug loads being queried in detail?

Many thanks

Chris
