Design and Evaluation of Energy Efficient Modular Classroom Structures

摘要

We are developing innovations to enable modular builders to improve the energy performance of their classrooms with no increase in first cost. The Modern Building Systems (MBS) classroom building conforms to the stringent Oregon energy code, and at$18/ft(sup 2) ($1.67/m(sup 2)) (FOB the factory) it is at the low end of the cost range for modular classrooms. We have investigated daylighting, cross-ventilation, solar preheat of ventilation air, air-to-air heat exchanger, electric lighting controls, and down-sizing HVAC systems as strategies to improve energy performance. We were able to improve energy performance with no increase in first cost in all climates examined.
