Solar technology systems are being studied, managed, built and offered as an effective alternative energy option. This publication presents background material for the building and operation of better sunspaces and greenhouses. Recent developments in solar technology are explained and information on solar greenhouse and sunspace is provided (in question and answer format) in these categories: (1) design; (2) construction; (3) management, maintenance, and safety; (4) horticulture; (5) construction workshops; and (6) information sources. Guidance in the identification of common mistakes in design. construction, and operation that affect performance of these solar structures is given. Suggestions to help consumers apply and utilize information on solar technology systems effectively are also included. (ML)
