Re: A zero-fossil-fuel studio?
A major concern with any thermal storage system is the moisture from
condensation on the surface of the thermal storage modules if a remote
storage bank is used. If the storage bank gets much above 60% rh some
rather nasty organisims will be growing in the air supply system with
possibly serious considerations for IAQ. The most succesful thermal
storage uses direct-gain solar mass walls rather than ducting warm moist
air to a storage bank. Water modules work well in the lower 48, and
gypsum board is better than masonry. Two or three layers of drywall is a
good compromise since only the first 1.5" to 2" is diurnally active.
a zero fossil fuel studio is quite feasible almost anywhere south of the
arctic circle.
