<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif;color:windowtext">Another method I have heard of is adjusting the U-value for the roof so that the product U*Area remains constant. The BTU’s of heat transferred through the roof
is the same. The roof load is not distributed correctly to the rooms below, which might be OK if it’s a big open space. This method follows the principle that you aren’t modeling the building, you are modeling the
<u>energy use</u> of the building. It is usually better to model the building as closely as you can, so I prefer Bruce’s method of putting an air wall under the boundary of the roof to make it easier to delete unneeded roof polygons. (An even better solution
is to use software that does not have this problem!)<o:p></o:p></span></p>
