About Cambridge Institute for Sustainability Leadership (CISL)

CISL’s new HQ will be in The Entopia Building, a retrofitted 1930s Telephone Exchange at 1 Regent Street, Cambridge. The building will be transformed into an ultra-low carbon sustainability hub, and home for CISL, fostering academic, government and industry leadership, collaboration and innovation to accelerate the global sustainability transition.
The standard-raising project aims to be a world first for a retrofitted sustainable office building with energy use, carbon emissions, impact on natural resources and user experience and wellbeing measured against multiple benchmarks


On arrival, all visitors will receive an induction before a presentation on the history of the project. Visitors will then be provided with PPE and escorted around the project by a member of the construction team where they can see first-hand the works that are taking place behind the scenes.

Information on Open Doors 2022 will be released shortly
