Description
This course provides a technical breakdown of the mechanics of infiltration (stack effect, wind load, and pressure differentials) and how air curtains mitigate these forces to reduce a building's carbon footprint. Participants will examine the research from the University of Concordia that led to the inclusion of air curtains in ASHRAE 90.1 and other major energy codes. From quantifying kilowatt-hour savings in diverse climate zones to identifying the "neutral pressure line," this session equips professionals with the data needed to justify air curtains as a cost-effective, space-saving sustainability solution.

Objectives
- Differentiate between stack effect, wind load, and pressure differentials, and identify how the neutral pressure line shifts based on building height.
- Explain the principle of entrainment and why laminar airflow is critical for maintaining thermal separation at building entrances.
- Contrast the ROI, floor space requirements, and performance of air curtains versus traditional vestibules under high-traffic conditions.
