This document discusses how integrated project delivery (IPD) and building information modeling (BIM) can enable sustainable and smart building design. It provides three case studies that achieved energy savings of 40-50% through early stakeholder engagement in sustainable studies as an integrated process using BIM. IPD-BIM approaches allow for performance-based design, reduced costs and timelines, and near 100% cost certainty through collaborative design, energy analysis, and construction simulation.
