Performance-Based Building Design provides a detailed exploration of designing buildings to meet specific performance objectives rather than prescriptive rules. Covering safety, energy efficiency, occupant comfort, resilience, and sustainability, it offers practical frameworks, case studies, and regulatory context. Written for architects, engineers, surveyors, and policymakers, it explains how to set measurable performance targets, model outcomes, and evaluate designs against real-world scenarios. By blending theory, technical guidance, and applied examples, it equips professionals to create innovative, cost-effective, and high-performing buildings tailored to their intended use.
