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?
