CIBSE has launched a new engineering guidance document, Embodied Carbon in Building Services: A Calculation Methodology for North America (TM65NA), developed in collaboration with ASHRAE.
This guidance emphasises the importance of assessing the embodied carbon in building services systems, covering emissions across a product's lifecycle - from manufacturing and installation to maintenance and end of life. While operational aspects and recycling potential are excluded, the methodology provides a comprehensive framework for calculating the embodied carbon impact, which is vital for managing a building's lifetime emissions.
TM65NA supplements CIBSE's TM65, with specific assumptions and guidance tailored for the North American market, covering the United States, Canada, and Mexico. The publication continues CIBSE's efforts to advance industry knowledge on embodied carbon through a series of publications, digital tools, webinars and collaborative projects.
