This manual is intended to guide developers, site planners, and builders in designing residential developments so that access to sunlight is maintained for planned or potential solar collectors. Almost any housing development can be designed to facilitate the use of solar energy. Differences are not in costs but in planning. Described in this guidebook are the major elements of planning a housing site to protect solar access. These developments are: (1) site selection and analysis, (2) preliminary site planning, (3) general design approaches and techniques, (4) specific design strategies, (5) landscaping and plantings, and (6) covenants and easements. Also presented are two case studies which demonstrate the application of approaches and techniques discussed. Over 100 figures and tables supplement the written material. (WB)
