Material passports launched at the Edenica building in London

The materials passport concept has been adopted to facilitate the reuse of components and materials at the end of the life of the new building.

The 94,000 square foot Edenica building, designed by Fletcher Priest Architects for BauMont Real Estate Capital and YardNine, is under construction in the City of London, with Keltbray currently undertaking preparatory work demolition work.

As part of the development’s approach to reducing carbon throughout life and creating a platform for material circularity, structural engineer Waterman is creating material passports for the project.

Material passports are digital data sets that record the characteristics of materials and components, giving them value for current use, recovery and future reuse. Edenica will serve as a pilot project for their implementation and is the first project within the City of London to be designed as a storage bank where materials are kept for future reuse.

Working with the Third London Wall project manager, Waterman’s sustainability team defined the sourcing route to ensure material passports contain key characteristics of selected building materials held in a database . This can be used to provide reporting on maintenance and potential future reuse over the life of the building and beyond, maximizing both material life and whole life value.

Edenica’s material passports will become a record of building elements, providing data on the materials, products and components that have been used. These records will enable the reuse of materials during the building’s operation or at the end of its life, transforming the materials used into resources rather than waste.

Material Passports are seen as a key step in bringing a functional circular economy to the built environment, but, to date, there is no standardized framework to define the process for their production, content or design. form. Waterman is currently creating a protocol to standardize the process of producing and reporting material passports across the UK. He collaborates with the Building Research Establishment and an EU research project called Circular Construction in Regenerative Cities (CIRCuIT). The City of London Corporation is also involved. The objective is to create a standardized model of material passports for all new products that can be supplied by manufacturers and suppliers.

Waterman’s sustainability partner, Anastasia Stella, led the development of Materials Passports at Edenica. She said: “It is extremely important that as construction professionals we continually try to move forward and innovate to help tackle the climate emergency. Our Materials Passport initiative shows how even the simplest concepts can create the potential for significant lifetime carbon reduction and maximize material reuse in the future.

Waterman specialists used data originally based on information provided by cost consultant Arcadis. The information included in the material passports comes from the building contractors. The information is based on 3D models, contractor records, product specifications and certificates.

Waterman’s team provides technical advice to support the development of an online platform called Circuland that enables the creation, viewing and maintenance of digital material passports at all levels of building, development and town. The platform will be used for digital storage and visualization of material passports, and the database structure will follow the level 2 sub-elements of the RICS NRM classification system (RICS, 2021). This will allow material passport information to be linked to post-completion circular economy claims and post-construction lifetime carbon assessments.

For developers, BauMont Real Estate Capital Managing Director Natalie Harrison said, “Our philosophy when it comes to development and renovation projects is to take a ‘use less, waste less’ approach. We engage sustainability specialists early on in our projects to ensure that our desire to deliver buildings with best-in-class ESG credentials is taken into account from the earliest design stages. This leads to better collaboration and fosters innovation, a good example of which is Waterman’s hardware passport initiative at Edenica, which goes beyond politics, setting a new precedent for London.

YardNine co-founder Maxwell Shand added, “Supported by low operational energy and an innovative approach to reducing embodied carbon, Edenica will demonstrate what can be achieved when sustainability is at the heart of YardNine’s design philosophy. a system. I believe that Waterman’s Materials Passport initiative will quickly become widely adopted as a “best practice” for responsible development.
