Capability
The greenest building is the one that already stands. We extend the life of existing structures with deep-energy upgrades, adaptive reuse, and Passivhaus-level performance standards.
Retrofitting is the most impactful climate strategy available to the built-environment sector. We approach every existing building with the same rigor we bring to new construction — measuring, modelling, and upgrading to meet modern standards.
Our team are certified Passivhaus designers and LEED APs who specialise in deep-energy retrofits. We balance thermal performance with heritage sensitivity, ensuring that improved efficiency never comes at the cost of architectural quality.
From fabric-first upgrades to full MEP overhauls, our retrofits typically reduce operational energy by 60-80% while improving comfort, air quality, and asset value.
Energy modelling, thermographic surveys, and fabric testing to establish baseline performance and identify weak points.
Insulation upgrades, airtightness improvements, high-performance glazing, and thermal-bridge-free detailing.
MVHR, heat pumps, solar PV, and smart controls that replace fossil-fuel heating with efficient electric systems.
Passivhaus EnerPHit, LEED, or BREEAM certification; post-completion monitoring to verify in-use performance.
What We Deliver
Whole-building fabric upgrades targeting 60-80% energy reduction, designed to Passivhaus EnerPHit standards.
Converting underutilised buildings into new uses — offices to residential, industrial to cultural, and more.
Recladding, window replacement, and thermal upgrade strategies that transform building performance and appearance.
Replacing fossil-fuel heating with heat pumps, MVHR, and smart building management systems.
Sensitive retrofit of listed and heritage buildings, balancing conservation requirements with performance goals.
End-to-end Passivhaus, LEED, and BREEAM certification management, from early design through final compliance.
Let's Talk
Whether you own a single building or manage a portfolio, we can help you plan and deliver a deep-energy retrofit.
