New TM65 embodied carbon guide aimed at North America

The guide emphasises the importance of assessing the embodied carbon in building services systems, covering emissions across a product’s life-cycle

CIBSE has published new guidance for assessing embodied carbon in building services systems, with assumptions tailored to the North American market.

Embodied carbon in building services: a calculation methodology for North America (TM65NA) was developed in collaboration with ASHRAE, and emphasises the importance of assessing the embodied carbon in building services systems, covering emissions across a product’s life-cycle – 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 to 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, and webinars.

There will be a panel discussion on experience using TM65 at CIBSE Building2Perform Live on November 13 at London ExCeL (www.build2perform.co.uk)

TM65NA is available on the CIBSE Knowledge Portal. www.cibse.org/knowledge
