Roles of building performance assessment in stakeholder dialogue in AEC

This paper treats rational expressions of building performance in order to better support dialogues between stakeholders in the design process. These expressions are based on the notion of objectively quantifiable performance measures, which are introduced through a set of “performance indicators”. The indicators can be used to quantify expectations and fulfillments in structured dialogues between different stakeholders. Two types of indicators are introduced based on: (1) normative models in biophysics and physiology; and (2) empiricist models of Environment-Behavior studies. The treatment is positioned to support rational decision-making during different stages of building delivery and use. The focus is specifically on the fulfillment of client expectations during design evolution.
