The Chartered Institution of Building Services Engineers (CIBSE) has launched its new Embodied Carbon Calculator tool

Engineers can easily estimate the embodied carbon associated with mechanical, electrical and public health systems in buildings, for the first time. Actuate UK, the voice of engineering services, has welcomed the launch of CIBSE’s new Embodied Carbon Calculator.

The digital Embodied Carbon Calculator 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.

How to use the calculator

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.

Carbon impact measurements

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.”
