MASS TIMBER THROUGH A LIFE CYCLE LENS

Envelopes: Embodied Carbon Meets Thermal Performance Focusing on envelopes, this year's case studies stood in stark contrast to the highly emissive, thermally low-performing, aluminium-based unitized glazing systems of the multi-residential buildings that we examined last year. [...]industry-wide generic Environmental Product Declarations (EPDs) can be significantly different to manufacturer-specific EPDs for the same product class. A Whole-Life Carbon Perspective Finally, the benefits of mass timber are most significant if we are able to take a whole-life carbon perspective that accounts for upfront material emissions, reduced life-cycle operational emissions, and future disassembly and reuse of structural materials. Marrying the reductions afforded by mass timber's biogenic storage capacity with high-performing, low-GWP façade systems can result in buildings with significantly reduced footprints upfront, as well as over the life of the project.
