This report is the first in a series of energy use studies intended to provide real life examples of the implication of energy conservation practices. Research reports from five public school districts describing their methods of measuring and conserving energy are summarized. While investigating the responses of various school districts to the energy crisis, BSIC arrived at some conclusions regarding the current energy situation and the possibility of coping with it by rational procedures. These conclusions, discussed in the final section, relate to (1) the problems of analysis using existing tools, (2) the need for design and operation energy use guidelines, and (3) the need for more complete energy use studies.
