*A guide is given for engineers, architects, and individuals familiar with heating and ventilating applications, who wish to design a solar heating system for a residential or small commercial building in the Pacific Coast Region. Both air and liquid space heating systems and domestic hot water heating applications are presented in detail. Passive space heating and swimming pool heating systems are discussed qualitatively;a quantitative analysis is not available at this time. Sources of information are listed, and design considerations, collector types, and collector coolants are discussed. The active systems described and studied are as follows: (1) domestic hot water heating using liquid heating collectors;(2) space heating using liquid heating collectors, water heat storage, and forced air distribution;and (3) space heating using air heating collectors, rock-bed heat storage, and forced air distribution. Performance charts are presented for the three types of active solar heating systems. The analyses are based on hour-by-hour computer simulations using actual weather data from seven Pacific Regional cities. The required collector area has been determined for these cities in the four-state region, Arizona, California, Oregon, and Washington. A simplified approach to collector sizing is presented based on monthly solar radiation and temperature data. The effects of variations in importantdesign parameters have been studied extensively for Fresno, California, and are presented in graphical form. However, much of the information in the Handbook is generally applicable.
