This bulletin is intended as a resource for school system facility planners and architects who design schools. Ways in which decision makers can incorporate environmental concerns in the design of school buildings are detailed. Focus is on the design of interior partition systems. Partition systems in schools serve several purposes; they define space, provide acoustical privacy, and myriad other functions. Some traditional criteria for such partitions, along with some building ecology criteria, are detailed. Various partition types such as concrete masonry unit partitions, gypsum wallboard over metal studs, straw panels, and operable partitions are described. Different features of each partition type, such as environmental issues, maintenance, and repair, are provided. Recommendations for what to look for in a particular partition system are offered. A decision-making process is outlined, which features various criteria: durability, cost, acoustics, flexibility, maintenance, recycled content, embodied energy, indoor air quality, and raw materials. In conclusion, although there is no perfect system for building partitions in schools, the most commonly specified systems are relatively favorable from an environmental standpoint.
