Accessible Indoor Air in the Built Environment

Accessible Indoor Air in the Built Environment


This project has been funded in part by Accessibility Standards Canada, Government of Canada, with ethics approval from the Women’s College Hospital, Toronto

Participate in the research project

We are pleased to announce our research project on Indoor Air Quality (IAQ) and accessibility in the built environment for people with Multiple Chemical Sensitivity (MCS), other disabilities and health conditions. Our main focus and priority area of research lies within the built environment, which includes the physical spaces constructed by people for human activities (such as buildings and urban areas where people live, work, play, or visit). Our research delves into how practices, space design, and building materials used within these spaces impact indoor air quality.

Indoor air quality plays a critical role in the well-being and accessibility of built environments. Canadians spend approximately 90% of their time indoors, making the quality of indoor air a crucial aspect of their daily lives. For individuals with certain disabilities, the quality of indoor air can become a barrier to accessing employment, programs, and services. Volatile organic compounds (VOCs), which are sources of indoor air pollution, are commonly found in cleaning products and personal care items. The usage of these products thus contributes to indoor VOC levels.

Our research aims to address the pressing need for studying built environments and accessible indoor air. By conducting extensive research on indoor air quality, we hope to identify potential barriers that hinder accessibility and propose solutions to create more inclusive and healthy built environments.


The study aims to focus on five key areas related to indoor air quality improvement and accessibility in the built environment:

  • Identify correlations between built environment characteristics and indoor air quality testing results.
  • Understand how IAQ policies are interpreted by administrators and building operators.
  • Explore the relationship between occupant comfort and indoor air quality.
  • Assess knowledge and awareness of indoor air quality maintenance among stakeholders.
  • Understand attitudes and beliefs towards IAQ policies for better policy development.


Indoor Air Quality Testing

We will sample and analyze indoor air quality in buildings with fragrance/scent-free policies and compare them to spaces without such policies. This data will identify airborne contaminants and their likely sources.

Building Characteristics Survey

A detailed survey will record information about each assessed space, including building age, materials, HVAC systems, occupancy type, and the presence of IAQ-related products like air fresheners.

Policy Survey:

Through this survey, we will examine the elements and implementation of IAQ policies, as well as the ease of reporting and monitoring compliance. Additionally, perceived barriers to IAQ policies will be explored.

Occupant Survey:

A survey administered to all building occupants will gather information about their comfort levels, symptoms attributable to IAQ, existing health conditions, and support for fragrance/scent-free policies.

Join the Focus Groups!

We are searching for participants to join our focus groups and share their experiences.

To be a part of our focus group, kindly complete the pre-screening questionnaire by following the provided link:

Do you know individuals in your network or community who experience discomfort or symptoms from exposure to fragrances, including scented and other products and who face IAQ-related challenges that impact accessibility to the workplace, health care, or the community due to MCS, other disabilities or health conditions? If so, please consider sharing our screening questionnaire link with them:

Assist in the recruitment of scent-free environments/spaces

Have you ever come across scent-free environments/spaces in educational institutions or workplaces?

If so, we kindly request that you share with us the names and locations of these buildings using our form:
