CMHC Housing Design Catalogue /
Materials GuidePolicy, Strategy
The Materials Guide provides practical support to housing providers, designers, and builders using the CMHC Housing Design Catalogue. Developed by Ha/f Climate Design, it outlines guidance for selecting materials that are cost-effective, durable, and aligned with low-carbon construction goals.
The Guide emphasizes strategies to reduce embodied and biogenic carbon while supporting climate resilience and compliance with emerging codes and certifications. Material choices are grounded in whole-building life cycle assessments and tailored to the Canadian context, offering a balance of affordability, constructability, and performance.

University of Waterloo Mathematics Building Strategy, Certification
The UWM4 Life Cycle Assessment, conducted by Ha/f for Moriyama Teshima Architects, quantifies the embodied carbon of the University of Waterloo’s new Math 4 building. Focused on structure and envelope, the report identifies key emissions drivers—structural steel, concrete, and curtain wall systems—and outlines strategies to halve total emissions. With Toronto Green Standard alignment, it highlights opportunities in low-carbon material specification, circular design, and reuse, offering a replicable model for low-carbon institutional buildings.

The Cost + Carbon of Canadian Commercial Construction
Policy
The Mass Timber Institute at the Daniels Faculty of Architecture, Landscape and Design, University of Toronto teamed with Entuitive, Ha/f Climate Design, and Bird Construction to develop structural designs, life cycle assessments, and cost estimates for commercial buildings built in Vancouver, Calgary, and Toronto.
Working across four structure systems - reinforced concrete, steel, mass timber, and timber-hybrid - the project team developed schematic-level design, cost estimates, and regionally specific carbon data to reveal clear insights. /Read the Report
The Bentway Phase 1 LCA Strategy, Certification
Working with The Bentway, Ha/f Climate Design assessed Phase 1’s design and materials to understand their carbon footprint. The study found that concrete and paving are key sources of emissions, while green spaces store carbon. For future phases, the report recommends recycled materials, low-carbon alternatives, and nature-based solutions to create more sustainable and resilient public spaces.
Ha/f’s analysis supports The Bentway’s commitment to creating more climate-resilient and sustainable public spaces, while providing a valuable blueprint for reducing carbon impacts in urban infrastructure projects.
Clean Enery Canada: Building Toward Low Cost and Carbon Policy, Strategy
Ha/f co-authored Clean Energy Canada's 2025 report, Building Toward Low Cost and Carbon. Leading an architecture and engineering consortium, Ha/f conducted in-depth research on efficient building design strategies aimed at reducing both carbon emissions and construction costs.
The study analyzed case studies of townhouses, mid-rise, and high-rise buildings, demonstrating how smart design choices can lead to significant carbon and cost savings.

Climate Resilience GuidePolicy, Strategy
The Climate Resilience Guide by Ha/f supports the development of climate-adapted housing across Canada’s diverse regions. Drawing on designs from the Housing Design Catalogue, it outlines practical strategies to address key risks including heatwaves, wildfires, flooding, drought, storms, and permafrost thaw.
The Guide helps builders, designers, and policymakers integrate durable, low-carbon, and resilient features into new homes. Strategies are categorized by building, interiors and systems, and site, and include impact ratings to support informed decisions. Emphasizing site-specific adaptation and collaboration with professionals, the guide ensures homes remain livable and safe in Canada’s rapidly shifting climate.

City of Toronto Embodied Carbon Policy Primer Policy
Ha/f co-led the development of Ontario’s first embodied carbon benchmarking study, shaping policy guidance for municipalities. Through research and cross-sector collaboration, Ha/f provided critical data, analysis, and design insight to help cities measure and reduce building-related carbon emissions—supporting climate leadership in Ontario’s construction and planning sectors.
The Primer informed the City of Toronto incorporating embodied carbon requirements into the Green Standards - North America’s first city with absolute targets.
