Accommodation options are to purpose build, to use ready-made, or to rehabilitate. The paper argues that rehabilitation is the option most likely to provide for good fit between organization and building. The procurement process must be one which allows management to link decisions about the organization with decisions about the building, taking account of differing interest groups. It is suggested that a participatory form of postoccupancy evaluation is a managable basis for initiating environment/behavior change. The paper gives a step-by-step description of a touring interview method of evaluation in current use in New Zealand and summarizes the lessons learned from efforts to institutionalize postoccupancy evaluation as a normal part of building procurement. The paper concludes with the suggestion that participatory evaluation has utility as a way to involve different interest groups in reaching negotiated agreement in programming for rehabilitation and as a basis for improved overall performance of buildings.
