Project overview
c.1,300 apartments & c.50,000sqft commercial space supported through planning stage
c.1,300 apartments & c.50,000sqft commercial space supported through planning stage, working to RIBA 1-3. Developed comprehensive sustainability-led design principles; produced collaboratively through early-stage circular economy and whole lifecycle carbon assessments workshops. Delivered long-term solutions to future-proof ongoing development – due for completion by 2030.
Results
What Did We Achieve?
- Futureproofed a long-running development, incorporating solutions compliant with upcoming changes to Building Regulations
- Developed a comprehensive Energy Strategy compliant with both London Plan policy and the Berkeley Group’s high performance standards
Service Overview
Supported the design team through Concept Design & Planning stage, RIBA 1-3, to complete a range of sustainability and carbon reduction assessments, developing a comprehensive Energy Strategy.

Requirements
We were engaged to contribute to and provide consultancy on early-stage sustainability considerations ahead of commencement on a long-running project to deliver a mixed-use development.
Having worked with Berkeley Group on a number of projects, we had a good understanding of their high internal standards for energy performance and carbon reduction.
Challenge/Opportunity
The client was also keen to get ahead of new regulations and avoid redesigns when the Future Homes Standard comes into force (expected in 2025). As a long-running development, ongoing to 2031, a comprehensive, ‘futureproofed’ Energy Strategy was essential, to remain both compliant and buildable while also supporting the client to set realistic budgets.
The development would also be delivered during the AD-L 2021 transition period. We commenced our consultancy working to the AD-L 2013 regulations, and frameworks for SAP 10 emissions and TM59 overheating.
As the design developed, the requirements of AD L and AD O 2021 became applicable, prompting revised design inputs and compliance advice.
Deliverables
- Developed high-level Energy Strategy, futureproofed to allow for the changing regulatory requirements under AD-L as build progresses through to 2031
- Coordinated Energy Strategy solutions in line with requirements of both the London Plan and Berkeley Group’s ‘Our Vision’.
- Delivered early-stage Circular Economy and Whole Life Cycle workshops with design team to ensure requirements were incorporated into the design process.
- Liaised with heating manufacturers to identify emerging technologies suitable for the development, specifically the use of exhaust air heat pumps.
Energist were also required to provide a compelling brief to demonstrate the suitability of these technology to the Greater London Authority.
