Thomas is a Sustainability Engineer with more than 15 years’ experience in environmental engineering, and sustainable design and construction. He has worked in the UK and abroad, in architectural and engineering firms.

Thomas set up Etude (2012), a sustainable engineering practice based in London with a particular expertise in very low energy buildings. His aim has always been to find the most appropriate environmental response on projects, including the Passivhaus Parliament Hill School in Camden; the refurbishment of Grade I listed Somerset House East Wing; research into energy efficient retrofit opportunities for Tower Hamlets, or the exemplar East Wick and Sweetwater development in the Queen Elizabeth Olympic Park.
