This three-day course equips building professionals with essential knowledge to improve airtightness and compartmentalization in multifamily buildings. Participants explore how air leakage affects energy efficiency, moisture control, indoor air quality, and occupant comfort, while learning to identify common leakage pathways. The training covers practical air sealing techniques for exterior envelopes and interior partitions, with a focus on managing inter-unit airflow while meeting fire safety and acoustic requirements. Learners also gain experience applying proven field techniques and interpreting performance test results to verify outcomes in both new construction and retrofit projects. These skills help professionals meet evolving energy codes and green building standards.
By the end of this course, participants will:
This course supports the low-carbon economy by equipping building professionals with practical skills to reduce energy waste caused by uncontrolled air leakage in multifamily buildings. By improving airtightness, participants help lower heating and cooling demands, directly reducing greenhouse gas emissions. The training aligns with recognized green building standards and promotes high-performance building practices that enhance energy efficiency, indoor environmental quality, and resilience. Its focus on scalable solutions in high-impact residential sectors enables meaningful reductions in energy use and carbon emissions across building portfolios.
