Sustainability Lead at SOM London Sustainable Engineering Studio since December 2021; helping to form an in-house environmental design and analysis support team working on projects in various climates across the EMEA region from building to masterplan scale. Prior to joining SOM, Herman was Sustainability Lead on a number of projects and Head of the Research and Innovation branch at ChapmanBDSP.

Herman has been a tutor at the Architectural Association Sustainable Environmental Design Masters programme for ten years and his main area of interest is the drive towards net zero while ensuring occupant and pedestrian wellbeing through climate-responsive solutions.
