CS-2009 EAp2: Minimum Energy Performance
Hello all,
Two little questions:
1) If I had automatic internal draps, would I be obliged to simulate them in the baseline/proposed building?
2) Is it possible to consider, as for the lighting system, an occupancy sensor for the fan coil system (for example reducing at 90% the maximum fan's electric energy consumption)?
Thank you in advance!

Ciao Fabio,
1. Always model the proposed as designed. The baseline would be without shades. See Table G3.1.1-5 Proposed (d). You could likely get away without modeling them if you can make the case that your results are conservative without them, which seems likely to me.
2. Yes you can. Sounds like you will need to do it as an exceptional calculation. You will need to back up the claim of savings with a study or other documentation.

Hi Marcus,
Don't you think that if I turned off the fan coil I could lose the temperature control (not acceptable for Leed)?
Thank you very much!

I would assume that when the space is unoccupied your system would revert to the unoccupied temperature setting and cycle back on if it reached the unoccupied minimum set point.
I suppose you could have temperature control issues depending on how you model it. If you are concerned about too many unmet load hours there is one way to find out . . .
