Educational Facilities Laboratories is developing a computer-based technical service--The Public Schools Energy Conservation Service (PSECS). As presently envisioned, PSECS would be capable of providing each participating district with information in five areas: (1) guidelines and instruction for establishing an energy usage data base; (2) a comparison of the energy usage at each of the district's plants with guidelines established by computer simulations and a nationwide data base of similar schools; (3) a "self-help" plant operations audit; (4) a cost-benefit analysis of modifications requiring capital investments tailored to each school plant; and (5) guidelines for monitoring the results of district decisions in each area of modifications.
