Senior Partner

I lead the Practice’s work on building performance, advocating a Soft Landings approach and encouraging project teams to engage with operational issues from design through to post-occupancy. I am keen to provide operational support to the users and managers to help them get the most out of their building.

My involvement in post-occupancy work began as Project Engineer on the Renewable Energy Systems Headquarters. After delivering the project through design to practical completion, I was able to observe the building in use for two and a half years. Through this experience, I saw first-hand just how much operational use differs from design expectations and how I could help lessen the gap. Here, and again at the Hayward Gallery, I was able to help fine-tune the systems to maximise comfort and minimise running costs.

I have also worked with University College London to investigate the energy performance gap in schools, co-authoring a paper, and I am an active member of the BSRIA Soft Landings User Group.
