The purpose of this manual is to consolidate into a single document all the maintenance and operational steps that, when implemented, will result in the lowest energy use consistent with school educational programs. The manual describes procedures for keeping the building and its equipment well maintained and efficiently run, establishing realistic standards for the energy requirements for the various activities in the school and adjusting the equipment to provide no more than these standards, and scheduling so that electricity and fuel are used only where and when needed. An appendix at the end of the manual contains supplementary information, including a chart for troubleshooting the heating plant, instructions for the evaluation and modification of existing systems, schedules, tables and record blanks to be used in connection with the various procedures, and some other background information.
