Abstract: An architectural heat and moisture exchanger. The exchanger defines an interior channel which is divided into a plurality of sub-channels by a membrane configured to allow passage of water vapor and to prevent substantial passage of air. In some embodiments, the exchanger includes an opaque housing configured to form a portion of a building enclosure, such as an exterior wall, an interior wall, a roof, a floor, or a foundation.

Abstract: An apparatus for enhanced heat and moisture exchange between make-up and exhaust air streams includes a housing having an exterior wall defining an interior channel through which air streams may pass and a water vapor permeable barrier disposed within the interior channel so as to partition the interior channel into a plurality of subchannels. At least a portion of exterior wall of the housing comprises a light-transmitting material. The exchange apparatus may be implemented as a modular panel which can be integrated into the exterior walls or facade of a structure. Also disclosed is a preheating apparatus in fluid communication with one of the subchannels of the exchanger apparatus. The preheating apparatus also includes an exterior wall defining an interior channel and having at least a portion of the wall formed of a light transmitting material. One or more energy absorbing heating elements are disposed within the interior channel of the preheating apparatus.
