Actuate UK welcomes launch of Embodied Carbon Calculator

Actuate UK, the voice of engineering services, welcomes The Chartered Institution of Building Services Engineers’ (CIBSE’s) new Embodied Carbon Calculator tool.  For the first time engineers can easily estimate the embodied carbon associated with mechanical, electrical and public health systems in buildings.

The digital tool is designed to support consultants, researchers and manufacturers to implement CIBSE TM65 Embodied carbon in building services: a calculation methodology, by performing the calculations set out in the document. CIBSE Technical Memorandum 65, published last year, enables the calculation of embodied carbon of building services equipment when no Environmental Product Declaration (EPD) is available.

Embodied carbon is associated with the extraction of materials, manufacture, repair, disassembly and disposal. Environmental product declarations (EPDs) are a standardised way of showing the embodied carbon and other environmental impacts of a product. However, because of the complexity of building services products and their supply chains, very few building services equipment manufacturers offer EPDs.

Paul Reeve from Actuate UK’s Net Zero Group said:

“Communicating the embodied carbon of electrical and electronic equipment and other building services products is a new challenge, and opportunity, for our sector.

Buyers are increasingly requiring mechanical, electrical & plumping (MEP) contractors to show how they are including embodied carbon in their carbon impact measurements - the new toolkit provides a technically sound, but also highly pragmatic, approach to help both manufacturers and contractors achieve this”.

To use the digital Embodied Carbon Calculator tool, a manufacturer will complete the Manufacturer Form describing the materials used in the product. Using this data, a user can complete either a basic embodied carbon calculation, when limited information is available, or a more robust mid-level calculation. Once the user has added contact details and completed consent to publication details, the result may be used as a self-assessed value for the embodied carbon of the product.

Using this tool as a supplement, TM65 will provide engineers with a consistent approach to the way embodied carbon calculations for building services products are carried out and reported. 

Actuate UK, the alliance of eight engineering services bodies, is helping the industry deliver net zero carbon targets. Find out more about Actuate UK’s net zero work.

New industry research to address net zero skills challenge in engineering services

14 March 2022

Engineering services alliance Actuate UK is working with Energy Systems Catapult (ESC) – an independent, not for profit, centre of excellence for energy systems innovation and transformation for net zero - on a strategy to boost the creation of a skilled workforce that will play a central role in reducing emissions from the built environment and deliver on the government carbon targets.

Actuate UK welcomes rise in apprenticeships, but warns of net-zero skills shortage

07 February 2022

Actuate UK, the voice of Building Engineering Services, warn that skills shortages are hampering ambitions to deliver net zero emission buildings. While the number of Engineering Services apprentices starting out in England in 2022 is back to pre-COVID levels, many more new starters are needed if we are to achieve net zero by 2050.

Actuate UK puts retrofit centre-stage in climate action for the built environment at COP26

11 November 2021

Engineering services alliance Actuate UK calls for industry and government collaboration on the challenge of retrofitting and decarbonising our existing buildings. Actuate UK presented as one of the Construct Zero partners in Construction: The Built Environment session which took place on Thursday 11 November 2021, 9:30am-11am, at the Green Zone of UN Climate Change Conference (COP26).
