Hello All:

I am looking for a fairly straight forward to model a "Cool Roof" in
eQuest.

My general understanding would be to do a Parametric Run, changing the
outside emissivity from, say 0.75 to 0.3. But I am getting VERY little
energy benefit.

My building is a 140,000 sf office, 2-story (70,000 sf roof). It has a
CW VAV system with HW reheat, and return air is through ceiling plenums.

I am only seeing about a 50,000 kWh saving out of 11,000,000 kWh HVAC
usage.

Any experience, suggestions?
