• Consideration of extreme weather events: The code accounts for the potential impact of extreme weather events, such as high winds and heavy snowfall, on building performance.

4. Emphasis on Sustainable Building Materials: The 2024 code promotes the use of sustainable building materials and practices to minimize environmental impact:

• Increased use of recycled materials: The code encourages the incorporation of recycled and reclaimed materials in construction, reducing the demand for virgin resources.
• Emphasis on life-cycle assessment: The code promotes the consideration of the entire life cycle of building materials, from extraction to disposal, to minimize environmental burdens.
• Reduced embodied carbon: The code aims to reduce the embodied carbon footprint of buildings, which refers to the greenhouse gas emissions associated with the manufacturing and transportation of building materials.

5. Streamlined Approval Processes: The NBCC 2024 aims to streamline the building approval process through clearer language and improved organization:

• Improved clarity and readability: The code has been revised to improve clarity and readability, reducing ambiguity and streamlining the approval process.
• Enhanced digital accessibility: The code is increasingly available in digital formats, making it easier for users to access and navigate.
