Has anyone had any success modeling cool roofing
options (i.e. reflective or light colored surfaces) in PowerDOE? So far, I
have seen negligible results from the adjustment of roof construction
absorptance values (emissivity is also known to play a role, but there is no
input for this in PowerDOE). I have seen data showing cooling energy
savings from 0.06 to 0.54 kWh/sqft/yr, depending on building type. I am
getting only a very small fraction of this. Data collected in the
study was from facilities in the southern and western US, and I work primarily
on buildings in the Northeast.
My questions:
How well can I expect PowerDOE to
simulate this? Is there a better way to simulate cool roofing? Is
the sun simply too low in the sky in New England to yield substantial
savings?
Your thoughts are appreciated.
