  • About Conference

    Rising to new challenges: Connecting IEQ to a sustainable future

    The IEQ 2025 Conference will take place in Montreal, Canada.  Organized by ASHRAE and AIVC, this conference provides the opportunity to learn, network and engage with IEQ professionals dedicated to advancing the fields of indoor environmental quality. The IEQ 2025 Conference is also the 45th AIVC, the 13th TightVent and 11th venticool conference. 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.

    Topics for Papers and Seminars

    • 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
    • Lighting Performance and Metrics
    • Noise: How the environmental impact can be mitigated
    • IEQ in Indigenous Communities

    Keynote Title:A Performance Based Rating Ecology for Residential IAQ Management from IEA-EBC Annex 86

    Keynote Abstract: As the technical options for efficient IAQ management in residential buildings and their respective performances are becoming more diverse, we are faced with the need for a comprehensive approach to rating their merits. In IEA-EBC Annex 86, researchers and stakeholders from 43 institutes and 24 countries joined forces to develop consistent performance indicators, input data and modeling practices based on the latest available knowledge in the field. Their efforts are currently being implemented in ASHRAE, CEN and ISO standards. This keynote presents the general framework for performance-based assessment of IAQ management performance and the conclusions drawn from the experience in Annex 86.

    Biography: Jelle Laverge is a member of the Building Physics research group and chair of the department of architecture and urban planning at Ghent University with a research focus on residential ventilation. They are a part-time attorney-at-law at Uniqum Advocaten. They hold an M.Sc. in architectural engineering (2007), an ML in fiscal law (2011) and a PhD in engineering (2013) from Ghent University. They are the operating agent of IEB-EBC Annex 86, the secretary of ISIAQ and a member of the editorial advisory board of BAE and a member of ASHRAE. They were the scientific co-chair of BS2021 and the president of IA2016, ISIAQ’s flagship conference.

    Title:  Community Engaged Frameworks lead to Healthy and Sustainable Indoor Environments

    Abstract: On-reserve housing experiences higher rates of poor indoor environmental quality (IEQ) with many homes in critical need of major repairs. Overcrowded housing conditions, which are common in many on-reserve communities, have been associated with high humidity and moisture and may lead to increased mold growth. As such, it is critical that we explore community driven solutions through multi-dimensional Two-Eyed seeing approaches to improve indoor air quality and health and well-being of occupants.  Our team has partnered with multiple First Nations communities throughout Canada to co-develop culturally appropriate solutions to improve IEQ. Our program “From Harvest to House” seeks to empower community champions; leveraging storytelling, knowledge sharing, data collection, and capacity building to co-develop community-driven solutions to improve current housing inequities and challenges in communities. I will explore the current overarching challenges in IEQ, highlight the current gaps in on-reserve housing and provide an overview of approaches to tackling these large intersectional housing issues. To improve IEQ on-reserves, it is critical that we take time to listen to Indigenous leaders in crafting engineered solutions.

    Biography: Dr. Sarah Haines is an Assistant Professor in the Department of Civil and Mineral Engineering at the University of Toronto and the Principal Investigator of the Indoor Microbiology and Environmental Exposures (IMEE) Lab. She received her BS in Environmental Engineering and her MS and PhD in Environmental Science from The Ohio State University.  Her research focuses on healthy and sustainable indoor environments, with expertise in indoor air quality, microbial exposures, and housing self-sufficiency​ where she develops innovative methods to measure and mitigate pollutants and biological contaminants. A core aspect of Dr. Haines' work is community-based research, particularly through the From Harvest to House Program, which aims to co-develop pathways to housing self-sufficiency in Indigenous communities. She collaborates with local leaders, housing managers, and community members to address housing challenges, indoor environmental quality, and technical capacity building. Using a Two-Eyed Seeing approach, her team integrates Indigenous knowledge, storytelling, and emerging technologies to create healthy indoor environments. With a commitment to bridging environmental science, engineering, and community-driven innovation, Dr. Haines is at the forefront of research that empowers communities to build healthier, more sustainable built environments.

  • IEQ 2025 Preconference Summit: IEQ in Action: Healthy and Resilient Building Applications
