403.9.3 Pool covers. Heated pools shall be equipped with a vapor-retardant pool cover on or at the water surface. Pools heated to more than 90°F (32°C) shall have a pool cover with a minimum insulation value of R-12.
Exception: Pools deriving over 60 percent of the energy for heating from site-recovered energy or solar energy source.
IG Pool with attached spa with gas heater for both. I think it is practical to assume the pool will not be heated to more than 90*F, the attached spa will be heated above 90*F. I interpret the spa to require an insulated cover, what about you?
A minority of fellow inspectors do not want to touch this with a ten foot pole cause if the homeowner wants to waste money on heating let them but mind you they will readily enforce wall, floor, ceiling insulation. Others feel the attached spa is not the same as a stand alone spa, stand alone is more likely to get used, electric vs gas heater, blah blah blah...
