One Design, Inc., has designed and developed modular waterwall components that make up a system for passive solar space heating using a south-facing thermal storage wall. The modules can also be used as thermal mass storage for roof apertures and for greenhouse applications. The modules are constructed of fiberglass reinforced polyester and each is 95 inches long, 16.5 inches wide and 24.5 inches tall. Each module contains 94 gallons or 784 pounds of water. When stacked behind south glazing, they provide 52 Btu//sup 0/F per square foot of net glazed area. A stack of four modules has a height of 93.5 inches, suitable for an 8-foot interior ceiling; a stack of five modules is 116.5 inches high, suitable for a 10-foot interior ceiling. The modules are designed to stack on one another without requiring additional hardware and nest inside each other to reduce shipping costs. Prototype modules were fabricated and subjected to structural tests. They were found to be capable of supporting at least 4.8 times the load imposed by a five tank stack, well above the recommended safety factor of 2. Long term purity of the water in the containers was tested and evaluated and found to be within acceptable limits. Prototype modules were installed in One Design's Star Tannery House near Winchester, Virginia, and performance was extensively monitored from January to April, 1979. Based on the performance during the period, it has been estimated that the passive solar heating contribution would be 79.5% of the house's total heating requirement.
