Blanket of Warmth: A Hybrid Passive Heating System & Advancing Blue-green Infrastructure design

December 18, 2025

Join Sustainable Buildings Canada for a powerful and inspiring presentation on the Blanket of Warmth project – an award-winning hybrid passive heating system rooted in both technical innovation and Indigenous Ecological Knowledge.

Mold and moisture in housing is far more prevalent than many realize. As highlighted in the May 2025 ASHRAE Journal, mold issues affect a significant number of homes across Canada, particularly in First Nations communities – where this challenge has been described as a national “wicked problem.” On Star Blanket Cree Nation, more than 60% of homes face mold concerns, contributing to cold, damp, and unhealthy living conditions.

This project embraced the United Nations’ 17 Sustainable Development Goals as a framework for asking better questions – and created space for a unique blend of traditional cultural wisdom and modern engineering. Drawing knowledge from the tipi and ASHRAE radiant heating principles, the team developed an elegant, affordable HVAC solution that was accepted to the ASHRAE Building Decarbonization Conference in Greece (2022).

Through the lens of what Dr. Esam Hussein calls compassionate professionalism and social sustainability, this webinar explores how technical excellence and cultural understanding can work together to solve deeply rooted challenges.

Learning Objectives

  • Recognize the value of multidisciplinary work that includes Indigenous Ecological Knowledge.
  • Understand how hybrid HVAC hydronic systems can support renovations in the existing residential sector to meet 2030 climate goals.

You will also hear a second presentation by Dr. Corey Dawson (Dalhousie University) on advancing blue-green infrastructure design using synthetic 3D drainage channels – a new, geomorphology-informed approach to sustainable stormwater management and nature-based solutions in urbanized riverscapes.

Presenters:

Aura Lee MacPherson – CEO, Embodied Systems; Project Manager for Blanket of Warmth
Wendell Starblanket – Nehiyawak Knowledge Keeper, Starblanket First Nation
Dr. Corey Dawson – Assistant Professor of Landscape Architecture, Dalhousie University

Natalia Ortiz, student of Project Management Environmental (PME) program in Seneca Polytechnic, has an Environmental Engineering background completed at Universidad El Bosque in Colombia. She has always been involved in sustainability roles and projects that included Environmental Management Systems implementation, Water Treatment Systems’ design and operation, Hazardous and Conventional Waste management and minimization practices, as well as Ecosystem’s Conservation and Energy
Efficiency programs.

For the PME – Applied Project Management Course, Natalia developed a Green Roof Assessment Tool for Seneca Polytechnic’s Office of Sustainability, with the aim to provide green roof technology recommendations best suited to a particular scenario, taking into consideration multiple aspects of green roofs and buildings; infrastructure, design, materials, environmental factors, and costs, as well as the Toronto Municipal Code – Green Roof bylaw. Natalia also has a scientific journal publication as the main author of the project “Selection and sizing of industrial wastewater treatment units required at the
new maintenance, repair, and overhaul (MRO) aircraft facility owned by Avianca S.A. in Rionegro Antioquia” in the El Bosque University Journal of Technology.

Natalia strongly believes there are several research topics left to be developed, and the importance of
working towards Sustainability from different backgrounds, knowledge, and cultures to build strong, productive, and resilient communities.
With the vision of growing cities and infrastructure along with nature, always preserving and respecting the ecosystems’ attributes and services, Natalia would like to keep researching and acquiring more experience in Sustainability roles.

Emily is a second-year PhD student in Geography at the University of Toronto, and a co-operator of a small home renovation company, Magnus Home Improvements. Her research seeks to determine how single-family homes can quickly and best be retrofit to achieve Toronto’s emissions reductions targets – including net-zero by 2040 – as part of the TransformTO climate action plan. Specifically, she will assess the impact of municipal home energy reporting and disclosure programs, as well as produce recommendations for growing the retrofit labour force in ways that attend to the UN Sustainable Development Goals. Further, her research seeks to understand how home retrofit activities can be regenerative and produce net-positive impacts for humans and the environment towards transformative, place-based sustainability. When not at her computer, Emily can be found cycling with her kids to and from school or making funky sounds on her analog synthesizer.
