Evaluating Integrated Design Process of High-Performance Green Buildings

High-Performance Green (HPG) buildings are designed through an approach called Integrated Design Process (IDP). The approach emphasizes early collaboration of downstream stakeholders in upstream decision-making and consideration of interactions among various building systems (mechanical, electrical, etc.) by including the representatives of various disciplines in design team early on through the design process. Managing the IDP is of special importance if the teams are to be successful in achieving high-quality sustainable outcomes at regular prices. Therefore, owners and project teams need to comprehensively evaluate their performance on ‘integrated design’ in various points during project delivery in order to avoid the waste of resources and to improve efficiency. The main objective of this article is to use the Contextual, Input, Process and Product (CIPP) model of evaluation and apply a qualitative research to provide a framework for evaluation of IDP. The article reports the efforts and findings of researchers in this phase of a doctoral research project and presents the planned quantitative research design for its future phases.
