Energy strategy, building performance and sustainable engineering design.
Practical sustainability integrated into every engineering decision.
Our sustainability team works alongside our MEP engineers to ensure energy strategy, building performance and environmental compliance are considered from the earliest design stages.
By integrating sustainability consultancy with building services design, we ensure that energy reduction strategies are practical, cost-effective and genuinely deliverable.

Sustainability FAQs.
BREEAM is the world's leading sustainability assessment method for buildings. It evaluates environmental performance across categories including energy, water, materials, waste, ecology and management.
Part L of the Building Regulations sets requirements for the conservation of fuel and power. Compliance involves demonstrating minimum energy performance standards through SBEM calculations.
Overheating assessments (typically to CIBSE TM52 or TM59) evaluate whether a building will maintain comfortable temperatures during warm weather without excessive mechanical cooling.
Yes. We carry out net-zero carbon calculations, develop energy reduction strategies and evaluate renewable technologies to help clients achieve their carbon targets.
When sustainability and MEP design are delivered by the same team, energy strategy decisions are coordinated with building services design from the outset, ensuring targets are genuinely achievable.
Yes. Our building physics team carries out daylight factor analysis, sunlight hours assessment and glare modelling using industry-standard software.
