Energy Reference Energy Source Directory: A Guide to Products Used in Energy Efficient Construction (Iris Communications, 1993; 503/484- 9353). Three-ring binder, 11x12, 500 pages. $175. Life has been a whole lot easier around the office since Energy Source Directory arrived. Housed in a threering binder, the 500-page reference is the most complete and most useful guide to specialized products and materials for energy-efficient construction that I've seen. It's divided into 15 categories, including Air Leakage Control, Heating, Indoor Ventilation, Insulation, Lighting, Moisture Control, and Water Conservation. Each product listing has its own page and provides contact information, specifications, a list of applicable certifications and codes, and a product description ranging in length from a few sentences to several paragraphs. Products are indexed by manufacturer and trade name at the end
