Sustainable performance through design
ECE Sustainability delivers low-carbon, high-performance design strategies rooted in Passivhaus, retrofit, and whole-life carbon expertise. We combine creativity with precision to help clients meet net-zero goals; balancing beauty, functionality and climate responsibility with the confidence of proven experience.
Sustainability
Delivering low-carbon, high-performance buildings
Our sustainability ethos is grounded in building performance, not just promise. We prioritise measurable outcomes – delivering low-energy, low-carbon buildings through Passivhaus design, whole-life carbon analysis, and retrofit strategies that balance ambition with pragmatism.
Designing for people and planet means going beyond compliance. We integrate performance modelling, thermal bridging analysis and post-occupancy evaluation from the outset – ensuring our buildings don’t just look good, but work hard over time. This approach supports clients in achieving their net-zero goals while enhancing occupant comfort and long-term value.
“We now have the tools, data and design methodologies to deliver buildings that meet future standards today – from Passivhaus performance to deep retrofit and embodied carbon reduction. The challenge is no longer technical – it’s a question of commitment.” Patrick Osborne, Head of Sustainability, ECE Architecture
What we offer
We design and deliver certified Passivhaus buildings that meet the highest standards of energy efficiency, comfort and airtightness.
We provide whole-life carbon assessments and material impact analysis to support low-carbon design and informed specification.
We model, analyse and resolve thermal bridges to reduce heat loss, condensation risk and improve building performance, for both Passivhaus and Part L requirements.
We prepare sustainability strategies and planning reports aligned with policy, ESG goals and client ambitions.
We develop pragmatic retrofit strategies, from step-by-step upgrades to full EnerPHit or AECB Standard interventions.
We assess how buildings actually perform – using POE, monitoring, and analysis to close the performance gap.
Turning strategy into performance
Our process supports clients from concept to completion with clear, data-led decision-making at every stage.
Step 1
We define project goals early, aligning climate ambitions with planning, performance and practical delivery. Through feasibility studies, early modelling and carbon analysis, we build a shared foundation for success.
Step 2
We deliver integrated strategies from Passivhaus design and retrofit detailing to embodied carbon reporting and thermal bridging resolution, collaborating closely with design teams to ensure every decision supports your sustainability goals.
Step 3
We demonstrate results through evaluation. We track real-world performance via POE, energy data and qualitative feedback – giving clients the transparency to verify outcomes, adapt strategies, and build trust with stakeholders.
Deliver
This structured, responsive approach gives clients confidence that sustainability targets are not only set, but achieved.
