Data presented in this report indicate that solar space and water heating are possible in the Pacific Northwest. The first section of the report contains solar records from several stations in the region illustrating space heating needs that could be met, on an average daily basis, by solar energy. The data are summarized, and some preliminary planning hints are offered including analyzing a site for solar collector suitability, and a procedure for sizing a collector and storage tank. The second section discusses two of the earliest solar collector houses in the area and compares them with three well-known solar houses elsewhere. A selected bibliography on solar energy in architecture is included. The concluding section contains photographs and descriptions of local design solutions that exclude summer sun but welcome winter light, including the effects of trees and vines. Climatological charts, based on eight years of data from the weather bureau at the Eugene airport, are included for the purpose of exploring low-energy building design in general. (MLF)
