Solar cladding in new and retrofit applications
The most widely applicable and financially feasible new solar energy product of the 90`s is the simple, yet elegant {open_quotes}transpired collector{close_quotes}, patented and manufactured under the tradename SOLARWALL{reg_sign}. SOLARWALL{reg_sign} started its product life as a glazed collector in the early 80`s and was installed in over 30 major applications in Canada and northern United States with Ford Motor Company installing solar collectors on seven plants. A typical application was 10,000 - 20,000 sq. ft. of collector. Conserval Engineering`s quest for an improved collector culminated in the patenting in 1990 of an all metal H.P. SOLARWALL{reg_sign} or High Performance SOLARWALL{reg_sign}. The conventional gazing was replaced with a dark colored metal building panel perforated with thousands of small holes, thus the nomenclature of {open_quotes}transpired collector{close_quotes}. The sun`s energy heats the dark metal panel installed on the south wall of the building. The heated metal, panel heats a boundary layer of air on the surface of the panel and this preheated air is pulled at a very low rate (typically 2 - 8 cfm/sq.ft.) through the small holes and into the building. The advantages of the all metal H.P. SOLARWALL{reg_sign} are multiple. First and most important, the unglazed system does not reflect energy, and is 30% more efficient. It also is less expensive, fireproof, exempt from breakage, and more aesthetically pleasing with a wide variety of dark architectural colors and panel profiles to choose from. In northern climates (3,000 degree days and upward), a square foot of SOLARWALL{reg_sign} panels will typically capture 3 to 6 therms (MMBtu`s) of solar energy per heating season, or $1.50 to $5.00 per sq.ft. depending on location, fuel type, and costs. Destratification savings achieved by Conserval`s unique fan and duct make-up air distribution system can double these savings in high bay facilities.
