Air Movement for Energy - Efficient Comfort in Conditioned Spaces

OVERVIEW
This session unpacks how elevated air speed can dramatically enhance thermal comfort while reducing HVAC loads, embodied energy, and operational costs. From minimising ductwork to reducing stratification in winter, we'll explore how fan-assisted airflow can support passive design, improve air quality, and help design professionals achieve energy efficiency, cost savings, and sustainability targets in both new builds and retrofits.

LEARNING OUTCOMES
• Identify the factors that affect thermal comfort. (Design; Conceptual Design; 3.4)
• Name the 6 factors that affect thermal comfort (Design: Schematic Design; 4.7)
• Understand the use of elevated air speed to improve thermal comfort, air distribution, and energy efficiency in conditioned spaces. (Design 3.2; 4.4)
• Describe the design benefits of minimising ductwork, lowering HVAC first costs, and improving ventilation rates. (Design 2.2; 2.3; 4.5)
• Explain stratification and the energy-saving potential of de-stratifying a large open space. (Design 3.3)
