Passive Design Strategies for Thermal Performance in Architecture

Buildings account for nearly 40% of global energy consumption, and people spend 90% of their time indoors, making thermal performance a critical architectural concern. Thermal performance begins with spatial decisions—orientation, airflow, daylight, and opening placement—that influence heat absorption, retention, and release before mechanical systems are introduced. It is tied to thermal comfort, affecting occupant health, well-being, and productivity; research shows healthy indoor environments can improve learning and productivity by up to 15%. The article emphasizes that thermal performance is not only about reducing energy demand but also about maintaining comfortable conditions in response to climate, linking environmental performance, resilience, and space quality.
