“Attached solar sunspace” means a glazed extension to a building which acts as a solar energy collection device. Through direct radiation, natural convection or mechanical means, the energy is conveyed to a heat storage medium and reduces the building’s consumption of conventional energy. (Ord. 2310 § 28, 2000; Ord. 2020 § 2, 1994; Ord. 1252 § 1, 1982)
