Building Performance Engineering
Engineering, design and modelling services that improve building performance, reduce energy demand and optimise retrofit strategies — before construction begins.
What building performance engineering covers
Once we know how a building actually performs, the next step is to design the solution. Our engineering stage turns measured data into a buildable, cost-effective strategy using building physics, PHPP energy modelling and Passive House principles — led by a Certified Passive House Designer.
We predict how the proposed construction will perform — heat loss, moisture safety, thermal bridges, comfort and energy demand — before any work begins. That means fewer surprises on site and a building that performs as intended.
Design on evidence, not assumption. Modelling the solution first de-risks the spend and proves it will perform.

Our three service categories form one connected engineering journey. Each stage builds on measured evidence from the last.
