Sustainability

Low carbon thinking embedded in every project, from the first sketch to the final commissioning — because the buildings we design will shape our environment for decades.

Sustainability isn't a service. It's how we think.

Every engineer in our team understands that the decisions made at the design stage have a lasting impact on how a building performs — for its occupants, its owners, and the environment. We don't treat sustainability as a separate workstream or a compliance exercise.

Our BREEAM assessors and low carbon specialists work alongside our MEP engineers from the earliest stages of a project, ensuring that sustainability objectives are baked into the engineering strategy rather than retrofitted later.

What we do to build better.

🏆
BREEAM Assessment

We provide the complete range of BREEAM services — from pre-assessment reports at the start of design through to full assessment and post-construction evaluation. Our accredited assessors help clients understand where investment in sustainability will have the greatest impact.

🔬
Thermal Modelling

Dynamic thermal modelling allows us to test design assumptions before they become costly on-site realities. We simulate energy consumption, overheating risk, daylighting and natural ventilation to optimise performance and comfort in every climate condition.

🌿
Low Carbon Design

We challenge every project to minimise its carbon footprint — starting with a fabric-first approach, then optimising mechanical and electrical systems for efficiency, and finally exploring renewable energy technologies where they offer a genuine return on investment.

⚡
Renewable Energy

Our energy team evaluates the feasibility of solar PV, ground and air source heat pumps, CHP, biomass and other renewable technologies — providing clients with clear, honest assessments of costs, benefits and payback periods to support informed decisions.

📊
Energy Strategies

We produce compliant energy strategies for planning submissions across the UK, including London Plan strategies for GLA scrutiny. Our reports are clear, technically robust and designed to support planning applications and discharge conditions effectively.

📈
Monitoring & Reporting

Good design is only half the picture. We help clients establish energy metering strategies, monitoring systems and reporting frameworks that ensure buildings continue to perform as designed — and provide the data needed for corporate sustainability reporting.

Certified performance
across all ratings.

Our BREEAM accredited assessors have experience across the full range of ratings — from Pass through to Outstanding. We work with clients to understand what level of certification is appropriate for their project and investment profile, and we build the engineering strategy around achieving it.

How we approach sustainability.

01
Early-Stage Feasibility

We engage at the very beginning — before design decisions are locked in — to establish sustainability targets, evaluate technology options and set the engineering brief on the right footing.

02
Integrated Design

Our sustainability engineers work alongside our MEP designers throughout the design process, testing options through modelling and ensuring low-carbon thinking is embedded in every system specification.

03
Assessment & Compliance

We manage the formal assessment process — BREEAM, Part L, energy strategy — coordinating with the wider design team to gather evidence and produce compliant documentation for planning and building control.

04
Post-Completion Review

We support clients after handover — helping to verify that buildings are performing as designed and providing the data and documentation needed for certification, reporting and ongoing optimisation.
