Sustainability team highlights

The sustainability team has worked on several exciting projects in the last six months, contributing across a range of technical areas to embed sustainability across projects early in design.

Billet Road

Greengage was commissioned by Bellway Homes to provide a number of energy and sustainability services in support of the planning applications for Site A and Site B of the Billet Road Opportunity Site in the London Borough of Redbridge. For both sites combined, the proposals include the construction of 681 new residential dwellings and c.1,300sqm of non-residential uses including commercial and community spaces, on an area of 10.22 hectares that comprises an open-air storage facility, a kennel and cattery, and a scrubland with a partial historic unregistered and uncontrolled landfill site.

Greengage worked on the energy strategy for the sites, which includes connection to a new proposed district heating network served by heat pumps, as well as undertaking WLC assessments, overheating assessments, sustainability statements and the climate change ES chapter for both sites. We also completed a BREEAM pre-assessment and a circular economy statement for Site B.

As part of our involvement in the project, we worked closely with the design team and client to ensure that the proposals provided the required levels of energy performance and thermal comfort, informing design decisions around fabric specification and façade design, explored options to reduce the embodied carbon impact of the development, and provided guidance on circular economy principles that could be incorporated in the design.

Central Quay

Central Quay is a residential-led, mixed-use development on a brownfield plot in central Glasgow, upon which Greengage was appointed to undertake:

  • A BREEAM pre-assessment targeting ‘Excellent’
  • NZC co-ordination across the site
  • Whole life carbon assessment
  • Development of a NZC (operation & embodied) strategy for the existing and retained office building.

Working alongside the design team, bespoke appraisals of the various design solutions were undertaken enabling the project to target operational net zero, in line with the LETI definition, and RIBA Challenge embodied carbon benchmarks, as opposed to a standard one-size fits all approach to sustainable design. The scheme is currently in planning, however Greengage helped to successfully develop a pathway to achieve operational NZC on the PBSA and is finalising the details on the residential units.


Greengage worked on behalf of the National Trust to analyse the embodied carbon within their new Shugborough visitor centre. With many innovative materials used, bespoke calculations were undertaken to establish an accurate embodied carbon figure. Other considerations included the carbon impact of reusing materials already on site and how different end of life treatments would affect the embodied carbon of this unique building.

We are looking forward to further exciting projects in 2024 as the sustainability agenda continues to grow and new regulations and guidance come into force, such as the net zero carbon building standards. In particular, projects already in the pipeline include work with Imperial College on their campus sustainability brief and sustainability coordination for the new academic building, as well as work on the redevelopment of part of Dartford town centre with architect partners.
