<DIV><FONT face=Arial size=2>Hello World!</FONT></DIV>

<DIV><FONT face=Arial size=2>We are working on a LEED project. Our project must
comply with ASHRAE 90.1. One of the requirements of 90.1 is that slab-on-grade
floors have an F-value of 0.73. I am modeling the baseline and proposed
buildings in HAP v4.2. When I click on a defined space ("space properties"
box comes up) with a slab-floor-on-grade floor type and go to the "floors"
tab, I am asked to input floor area, total floor u-value, exposed perimeter, and
edge insulation r-value. I am pretty sure the first two are required
inputs.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Questions:</FONT></DIV>
<DIV><FONT face=Arial size=2>1. There is no U-value requirement in 90.1 that I
see for baseline case. Would I just use the proposed design U-value then?
</FONT></DIV>
<DIV><FONT face=Arial size=2>2. Where/how do I input the F-value? Is the
F-value somehow related to the edge insulation R-value?</FONT></DIV>

<DIV><FONT face=Arial size=2>Thank you in advance.</FONT></DIV>
