This manual presents guidance to facility designers, school administrators, staff, and students for the development of school facilities being constructed under Ohio's Classroom Facilities Assistance Program. It provides critical analysis of individual spaces and material/system components necessary for the construction of elementary and secondary schools and combination facilities. Following site selection and design criteria, the manual details the construction, design criteria, and standards for each school level's spaces, from administrative spaces, through various classrooms and specialized educational spaces, to food services and custodial areas. Construction specifications for all potential building materials are provided as are insulation specifications for thermal and moisture protection, specifications for doors and windows, finishes used, and equipment and furnishings. The manual also includes a CD-ROM version. (GR)
