Design and Evaluation of Energy Efficient Modular Classroom Structures.
Brown, G. Z.; And Others
This paper describes a study that developed innovations that would enable modular builders to improve the energy performance of their classrooms without increasing their first cost. The Modern Building Systems' classroom building conforms to the stringent Oregon and Washington energy codes, and, at $18 per square foot, it is at the low end of the cost range for modular classrooms. The study investigated daylighting, cross-ventilation, solar preheat of ventilation air, and thermal storage as ways to reduce energy use. Phase 1 of the research analyzed the heating and cooling loads of the baseline modular classroom building with its long side facing south in five different climates: (1) Astoria, Oregon; (2) Bakersfield, California; (3) Fairbanks, Alaska; (4) Honolulu, Hawaii; and (5) Spokane, Washington. The Honolulu model, with a simple payback of 1.3 years, came closest to achieving the objective of increasing the first cost of the unit. The second- and third-best-performing climates were Fairbanks and Bakersfield, with simple paybacks of 7.7 and 10.3 years, respectively. Spokane and Astoria followed with simple payback periods of 17.2 and 23.8 years, respectively. Phase 2 of the research will combine design strategies of improved electrical light-switching, perimeter insulation, shading, window sizing, preheater configuration and location, and HVAC (Heating, Ventilating, and Air Conditioning) locations, to reduce simple payback periods. Six figures are included. (LMI)
