What are TM65s & EPDs


What are TM65s and EPDs and why do they matter?

Sustainability is a core part of how projects are designed, specified, and delivered across the built environment. Whether you’re working on a refurbishment, a major rollout, or a new‑build project, customers increasingly want - and expect - transparent environmental data about the products going into their buildings. At Excel, we’re committed to making that easier for you. Two important tools include the  TM65 calculations and Environmental Product Declarations (EPDs). Both provide valuable insight into a product’s lifecycle impact, helping installation partners make informed, responsible choices.

What they are, how do they differ, and why they matter.
TM65: A Practical Way to Estimate Embodied Carbon

Not all products have full lifecycle datasets available, especially in structured cabling where components can be complex and varied. That’s where TM65 comes in. Developed by CIBSE, TM65 is a recognised methodology for estimating the embodied carbon of a product when complete environmental data isn’t yet available. It gives manufacturers and installers a structured way to calculate the carbon impact linked to:

Raw material extraction

Manufacturing processes

Transportation

Installation

Maintenance or potential replacement

End of life processing

For cabling infrastructure - where traditional EPDs may not always exist - TM65 provides a credible, consistent way to quantify environmental impact.

Why TM65 matters for Excel installation partners

TM65 helps you:

Understand the carbon footprint behind the products you’re installing

Support customers with sustainability reporting and ESG commitments

Meet the expectations of green building schemes

Compare options based on environmental performance

Make better procurement choices on complex projects

We have TM65 certificates for every Excel product in the range to provide full transparency. You can download the TM65 certificate for each product from the online catalogue under ‘Datasheets & Docs’ for each of the products.

EPDs: Verified, Standardised Lifecycle Data

If TM65 offers an estimate, EPDs go one step further. An Environmental Product Declaration (EPD) is a third‑party verified, standardised document that summarises a product’s environmental impact across its full lifecycle. They follow strict international standards including ISO 14025 and EN 15804, ensuring global recognition and consistency. An EPD typically reports on:

Raw material use

Manufacturing processes

Transportation

Installation impacts

Operational performance

End of life scenarios

Total lifecycle carbon footprint

Why EPDs matter for installation partners

EPDs support:

BREEAM, LEED, and other sustainability certifications

Responsible procurement frameworks

Transparent comparison between competing products

More accurate whole building lifecycle assessments

Clear, independent verification of a product’s sustainability credentials

Excel has developed EPDs for selected product families as part of our long‑term commitment to lifecycle transparency. If an EPD is available for a product, you’ll find it in the ‘Datasheets & Docs’ section - or you can download them directly here:https://excel-networking.com/downloads/environmental-product-declaration

How Excel is Supporting Data Driven Sustainability

TM65 and EPDs are part of Excel’s wider programme to deliver environmental transparency and help partners reduce the embodied carbon of their network designs. By adopting these frameworks, we’re helping you:

Build more sustainable, future ready infrastructure

Meet customer, regulatory, and certification requirements

Make informed product choices backed by verified data

Demonstrate measurable environmental progress

This work sits alongside our broader sustainability initiatives - from plastic free packaging, recyclable packaging and responsible sourcing to our ISO 14001 environmental management accreditation.
