CISL Entopia Building – Material learnings and reuse

CISL Entopia Building – Material learnings and reuse

The Cambridge Institute for Sustainability Leadership (CISL) needed a headquarters that reflected its own values, so it set about a deep green retrofit of the Entopia building, proving along the way that the most sustainable building is probably the one that already exists. The 1930s former telephone exchange in central Cambridge, used for offices since the 1990s has been refurbished to the Passivhaus EnerPHit standard and BREEAM Outstanding, and is aiming for WELL Gold certification.

Discover material reuse stories from the recently completed Entopia Building. ASBP and CISL will be joined by guest speakers to share success stories and lessons learned. Hear about the use of bio based and low carbon materials, altering glazing in a conservation area to help achieve the standards, the innovative PV array, and product and steel reuse.
