Measuring Embodied Carbon in Bespoke AHUs
Measuring the embodied carbon* of our bespoke AHUs is becoming more critical to our clients, as healthcare providers, commercial organisations and other industries seek to manage their own carbon footprint. Using CIBSE’s TM65 methodology, we are able to provide a mid-level embodied carbon calculation, along with the design data of each and every of our bespoke AHU products, from initial design stage.
Whilst Environmental Product Declarations (EPD’s) are generally considered the most reliable method to assess the environmental impact of a product, including its embodied carbon, at every stage of its lifecycle, the development of EPDs requires the involvement of an EPD operator, as well as third-party certification, which can be a lengthy and expensive process.
Furthermore, bespoke AHU’s are designed from scratch, with each product being unique in its configuration, size, weight and material composition making it impractical and costly to provide an EPD for every AHU. It would also be somewhat futile, because the information is needed at the earliest design stages, to allow sufficient time for the design team to make informed decisions. The very nature of a bespoke product means that the information required to calculate an EPD wouldn’t be available until after the AHU is manufactured.
Being able to apply TM65 methodology to establish a conservative estimate of the embodied carbon for our bespoke AHU products, in the absence of an EPD, is proving to be a valuable tool for our clients who increasingly demand sustainability metrics, alongside performance, quality and reliability assurance.

*Embodied carbon refers to the emissions associated with the process of extracting and transforming materials used for the manufacture of a product, as well as those associated with the assembly, transport, installation, maintenance, repair, disassembly, and disposal of the same product.
