The Modern Building Systems' (MBS) classroom building conforms to the stringent Oregon and Washington energy codes, and at $18/S.F. (FOB the factory) it is at the low end of the cost range for modular classrooms. We are investigating daylighting, cross-ventilation, solar preheat of ventilation air, electric lighting controls, and down-sizing HV AC systems.

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. The authors 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. The authors were able to improve energy performance with no increase in first cost in all climates examined. Two papers and a full report on Phase 1 of this study are available.

The system uses one-sided structural insulated panels (SIPs with one layer of OSB attached to foam insulation), a compacted gravel bed, and engineered lumber for the perimeter beam. Tests show that an on-grade panel floor system of 20 ft by 36 ft (6.1 by 11.0 m) is $895 less expensive and has a 55% better insulating value than an insulated concrete slab, exceeds deflection and flatness criteria for wood and concrete slab floors and supports structural loads in excess of those in residential construction. The flexible nature of the foam and wood may also improve the standing comfort of the floor compared to a concrete slab floor. In addition, the panel and engineered wood components increase the recyclability of the floor. The system is easily adaptable to use over an existing concrete floor.

The Modern Building Systems` (MBS) classroom building conforms to the stringent Oregon and Washington energy codes, and at $18/S.F. (FOB the factory) it is at the low end of the cost range for modular classrooms. The authors are investigating daylighting, cross-ventilation, solar preheat of ventilation air, electric lighting controls, and down-sizing HVAC systems. In Phase 2 the number of baseline buildings was expanded by simulating buildings that would be typical of those produced by MBS for each of the seven locations/climates. A number of parametric simulations were performed for each energy strategy. Additionally the authors refined their previous algorithm for a solar ventilation air wall preheater and developed an algorithm for a roof preheater configuration. These algorithms were codes as functions in DOE 2.1E.
