[Bldg-sim] Why should roofs have high emissivity?

[Chris Jones]

In some cases it may be counter productive to use a high emissivity 
roof.  I have worked on uncooled warehouses where the team used an 
approved roofing product to get that point but the heating energy 
increased enough to lower the savings enough to lose an EAc1 point.
