[Bldg-sim] Appendix G - Fan power

[Rosenberg, Michael I]

The 2010 version of Appendix G provides some good guidance.

G3.1.2.10.1 The calculated system fan power shall be
distributed to supply, return, exhaust, and relief fans in the
same proportion as the proposed design.

>From time to time we´re asked in LEED-Clarifications to break up the total fan-power into relief, exhaust, supply etc. Can somebody tell us what to do?
The calculation in the proposed is totally different and for the baseline we only use the 90.1 equations.

Betreff: [Bldg-sim] Appendix G - Fan power

Does the dot in the equation indicate multiplication? So should the equation read CFMS X 0.0013 + A?

The reason I am confused is that they use X in other places.
