[Bldg-sim] Easy Question

[Wilson, Luke]

John,

I'm assuming you are using ASHRAE 90.1-2007 Appendix G for your Baseline?
If so, the way I read it from Table G3.1 is that you should evenly distribute the WWR of the entire building, not for each floor. Therefore I would use 11.4% for each floor.

I have a two story building.  For the baseline I am evenly distributing the
fenestration.

The first floor window area is 462.2 ft^2
The second floor window area is 647.1 ft^2

The first floor wall area is 4858 ft^2
The second floor wall area is 4858 ft^2

In the base line model do I use:

First floor 9.5%
Second floor 13.3%

OR

First floor 11.4%
Second floor 11.4%
