Research

Measurements from homes and neighbourhoods influence decisions about repairs, funding and climate adaptation. Those measurements are often held by the organizations that collect them and may not be available in a useful form to the residents and communities they describe. We work with partners to decide what information is needed, how it should be collected and interpreted, and how the results can be used locally.

The three areas below make up the lab's research programme.

Coming: NOMAD. We are developing an off-grid mobile laboratory for building diagnostics, on-site material analysis, and continuous air-quality and weather monitoring in places where distance, weather and limited infrastructure make fieldwork difficult. The first field use is expected in late 2027 or early 2028. What NOMAD will include →

1

Make building diagnostics more accessible

The tools include low-cost sensor networks, models that predict when equipment will fail, and ways of checking a building against its own operating data. We adapt and test them for housing where automation systems, on-site technical support or consultant budgets may be limited, as well as for larger commercial buildings.

Low-cost indoor air monitoring for communities

Affordable, offline-capable monitoring for real homes, backed by testing that makes the measurements—and their limits—clear.

Fault detection & diagnosis

Physics-based fault detection, diagnosis and correction using existing airport building-automation data.

Electrifying small businesses

Following one completed heat-pump retrofit and one project that stopped at feasibility to understand what shapes small-business electrification.

2

Connect housing & health

We study how housing conditions affect health under a changing climate (e.g., extreme heat, wildfire smoke, cold, mould) and which households and neighbourhoods carry the most risk.

Housing, heat & wellbeing

How housing shapes exposure and response to extreme heat across three connected studies involving indoor conditions, health and lived experience.

Support community-led action

Our research is designed with community partners. Agreements made with each partner set the research priorities and determine how data are collected, accessed, interpreted and shared. Projects also include training and tools that partners can use after fieldwork ends.

From Harvest to House

A co-led collaboration linking housing assessments and environmental monitoring with community priorities, workshops and training.

Public scholarship & advocacy

We also use building-science and spatial evidence to contribute to public decisions.

Ontario Place tree removal: a before-and-after spatial record

An interactive 3D story compares Ontario Place in July 2024 with the site after clearing on October 3, 2024. It documents the removal of more than 850 mature trees and makes the scale of the landscape change visible, including its implications for urban habitat and public wellbeing.

Networks, codes and standards

We contribute to international research networks and to building-code and guideline work. This gives us a way to bring evidence from buildings and communities that are often missing from the data behind standards. Helen co-leads the Community Scale Equity and Sufficiency subtask of IEA EBC Annex 95 (Human-Centric Building Operation and Design for a Changing Climate, 2024–2029) and was a collaborator in Annex 79. She sits on the IBPSA-Canada and Building Science Specialist (BSS) boards, serves on the ASHRAE Guideline 45P committee, and serves on Canada’s National Model Building Code IAQ Task Group for dwellings.

Funding & support
