The conference “IEQ 2025: Rising to new challenges: Connecting IEQ to a sustainable future”, organized by ASHRAE and AIVC, will be held in Montreal, Canada on 24-26 September 2025. The conference will also be the 13^th TightVent and 11^th venticool conference.

This conference provides the opportunity to learn, network and engage with IEQ professionals dedicated to advancing the fields of indoor environmental quality.  Emphasis is placed on the growing understanding of occupant response to indoor environment elements (thermal, air quality, lighting and acoustics) while enhancing resilience in a changing climate. Seminars are led by experts from around the world representing AIVC, ASHRAE and many other partnering organizations.

Conference Topics

• Performance Metrics: For all aspects of IEQ
• Occupant Behavior: How behavior impacts IEQ and how IEQ impacts behavior – psychological dimensions of IEQ
• Smart Sensors, Data and Controls: Sensor properties, data management, cybersecurity, applications, commissioning, equivalence
• Resilience and IEQ: Responding to climate change and disasters
• Ventilation: Mechanical, passive, natural and hybrid systems
• Air Tightness: Trends, methods and impacts
• Thermal Comfort: Dynamic approaches, health impacts and trends acoustics/lighting, the visual/auditory aspect
• The Environment Around Us: Acoustics, lighting, glazing, interiors and impacts upon wellness
• Policy and Standards: Trends, impacts, implications
• HVAC and IEQ in a post-COVID world
• Ventilation and building decarbonization
• Lighting and Acoustics: How can the outside be brought inside or vice versa
