When work started on a code for energy conservation in buildings, a preference was expressed for a performance code rather than a prescriptive code. With this type of code, the level of performance or energy budget must be specified and will vary depending on factors including building occupancy and geographical location. This note is one of three giving suggested norms for energy consumption. Two school building layouts, one extended and one compact, were developed. The energy consumption of primary and secondary schools with these layouts was computed. The energy norms derived from these analyses were plotted and compared to recorded energy figures for existing schools.
