This is an exciting opportunity to take a role in the growing Sustainability and Building

Performance Team, to contribute to our commitment to help tackle the climate and biodiversity

emergency and to develop zero carbon buildings. As a Building Performance Modeller you will carry out building performance modelling across a range of metrics to support and inform our developing designs as well as analyse post occupancy evaluation generated data to understand and improve existing building performance. A key part of the role will be to develop bespoke parametric analysis tools, identify opportunities for optimisation and structures of iterations.

The clients Building Performance Team supports architectural designers to develop detailed and strategic plans for low carbon buildings. The team implements advanced dynamic thermal modelling and life cycle assessments to inform the architectural process since the early-design stages. Part of this role is communicating with our architects, clients and beyond. The team also carry out and publish independent research and post occupancy evaluation studies of our finished buildings. We are active outside the practice through teaching, advocacy and working with activist groups. A current research project is investigating Net Zero Carbon buildings with UCL and Innovate UK.

They have ambitious clients throughout the UK and internationally and their research-led, collaborative working method offers a friendly, rewarding and supportive environment for personal and professional development.
