Here we invite industry leaders to share their valuable insights and expertise on creating a sustainable built environment. This week we welcome Jake Timothy?Dorward , Senior Consultant for QODA Consulting.
The sustainability landscape has started shifting since the initial introduction of Whole Life Carbon and Circular Economy requirements for GLA referable schemes in 2020. This has caused a top-down trickle effect as local boroughs of London have started to adopt the same standard of assessments for many of their own schemes. It is no surprise given that 20% of building emissions are related to embodied carbon of newly constructed buildings, annually. Furthermore, and especially with operational performance of buildings continuing to improve, roughly 40-70% of a building’s whole life carbon emissions can be identified with its embodied carbon footprint. There is a clear focus with the GLA and local councils to retain the existing building stock, build less, and build well. The key to success relies on many different stakeholders.
The developer has a huge opportunity to influence the project from the very beginning as the most carbon savings are achieved before a plan has actually been conceptualised. It is critical for a developer to ensure that their company is educated at board level to be carbon literate, to identify risks and opportunities that arise with relation to a building’s whole life carbon footprint, and to continue to collect and reevaluate performance. It is recommended to engage a sustainability expert in-house to develop employer’s requirements, in line with planning requirements, that must be met on each project. Early engagement with design team will help to safeguard planning requirements by identifying project specific risks and opportunities.
The design team are integral to turn employer’s and planning requirements into a feasible design. This can be broken down into several critical stages. The first element to consider is to collaborate with all principal designers at the earliest stage of the project to discuss the principles of whole life carbon and to explore opportunities to reduce carbon emissions from the offset. Conversations should centre around existing building retention, building form, building structure, waste reduction, procurement, and designing for end-of-life. Once a strategy has been agreed, the main task at this stage is to effectively generate an accurate inventory of materials, with a bespoke and effectively communicated plan in place for each material throughout its useful life. It is critical at this stage that all requirements related to whole life carbon are properly specified including location of materials, recycled content of materials, reused materials, availability of EPD, construction methods, etc.
Early engagement with supply chain plays a huge role in delivering a project in line with the principles of whole life carbon. Designers should be reaching out to manufacturers to inform on requirements and request how far their products can be pushed. Increased demand will provide manufacturers with the confidence to re-strategize and deliver products that embody low-carbon technology. This enables more ambitious targets to be set at planning stage which will help buildings to push for aspirational whole life carbon benchmarks.
The contractor faces the challenge of piecing all of the design work together and delivering it in actuality. Procurement is one of the most pivotal items to get right at this stage, and technical submissions must be clear and robusdt in terms of whole life carbon requirements. One of the roles that has evolved most is the role of the quantity surveyor, who now needs to be literate in carbon as well as currency, and able to identify products that are most suitable to low-carbon construction. Furthermore, training should be provided regularly to site operatives to illustrate the best methods for reducing waste on site, as well as ensuring that materials are easily reachable and disassembled.
The supply chain faces the greatest challenge of developing products that are fit for purpose. Whilst contending with many other items such as fire safety of products, manufacturers have a responsibility to invest in innovating their processes to produce assets that are low-carbon, resourceful, designed for longevity and end of life. The most important piece of the jigsaw is to have verifiable products with explicit metrics of performance that can inform. This is an area of paramount importance with services, where data is currently extremely limited. TM65 was released in 2021 to act as methodology to measure whole life carbon impact of services without EPDs. The document highlights that a heating system alone can account for up to 25% of a building’s whole life carbon footprint. Manufacturers in the services sector have been provided the intricate challenge of producing third party verified EPDs in line with EN15804 standards to properly inform projects about their total carbon emissions. The challenge necessitates developing technology that is compact, efficient, containing low GWP solution, operable for 25+ years, and with maximum recycled content. No easy feat! A lot of great work from supply chain has come in remarkably simple yet effective fashion. For instance, leasing products instead of selling them, and communications with design teams between CAT A and CAT B to salvage and repurpose otherwise obsolete installations. The upcoming couple of years are going to have a huge impact on the future of whole life carbon with services joining structures and fa?ade at the forefront of whole life low-carbon design.
