Sunspace definition
Sunspace means an enclosure or room designed both as habitable space and as a passive collector/absorber for solar radiation. A sunspace must have the capacity for thermal separation from the building's occupied space; it may or may not be “occupied space”.
Sunspace means a passive solar space heating system in which a permanently attached useful space, physically separated from the conditioned space, permits solar radiation to pass through glazing where it is collected and stored by thermal mass, and from which heat is delivered into the conditioned space by controlled natural and/or forcedconvection; and
