Passive design is often seen as an alternative to mechanical systems, but its real value is far greater. When climate, comfort and building physics are understood from the outset, passive principles become a foundation for architectural and engineering solutions that work together. This approach enables buildings to naturally reduce energy demand, moderate internal conditions and make better use of environmental resources—often unlocking opportunities that would otherwise require larger, more complex or more energy‑intensive systems. 

Drawing on projects across diverse climates and building types, this session demonstrates how passive design can shape architectural form, influence spatial planning and redefine the role of building services. It highlights how strategies such as daylighting, solar control, thermal mass, natural ventilation and night‑time cooling can become core drivers of the design response rather than add‑ons. 

What this session covers: 

• Passive design fundamentals — How climate, comfort and building physics shape early design decisions.  

• Architectural form and spatial planning — Ways passive strategies influence massing, orientation and internal layouts. 

• Environmental strategies — Daylighting, solar control, thermal mass, natural ventilation and night‑time cooling as primary design drivers.  

• Integrating active systems — How mechanical systems can selectively enhance passive performance during peak loads. 

• Holistic design process — The benefits of considering architecture, building physics and building services together from project inception.  

• Case studies — Examples from multiple climates and building typologies demonstrating real‑world outcomes. 

The session is ideal for architects, building services engineers, sustainability consultants, developers and asset managers, project managers and facilities managers who are involved in shaping building performance, resilience and long‑term value. It will also benefit students and early‑career professionals looking to deepen their understanding of how passive and active design strategies can work together.
