Introduction

Achieving a net-zero carbon built environment throughout its entire lifecycle has become a critical global challenge. While new construction in developing countries holds significant potential for emissions reduction, retrofitting existing buildings in developed nations presents the greatest mitigation opportunities. However, current building management systems are primarily designed for expert users and do little to guide occupants toward sustainable behaviors.

To address this, SUTD initiated a new interdisciplinary effort focused on participatory building sustainability. This approach integrates sensor technology, real-time analytics, and intuitive user interfaces to raise awareness of energy consumption and environmental conditions. The aim is to empower all occupants—regardless of technical background—to engage in more sustainable habits and contribute to energy efficiency goals. Early trials show promise in encouraging behavioral change and lowering cooling-related energy demand, offering a more inclusive path toward sustainable building operations.
