Who are we are and what do we do? 

This is a new group that has started with Tim Martel as the group leader. Tim organised Transition Stroud’s Open Homes 2018 and has plenty of contacts for visits in the surrounding area. Please also contact him if you’d like to suggest a visit.  Tim is one of our tutors on the CarbonLite retrofit course and is also an AECB Expert Advisor.

New monthly AECB visits of energy efficient eco homes are starting in the Stroud area. Visits are open to all and no booking is required. Each visit will be a guided tour lasting around an hour, similar to Transition Stroud’s Open Homes but only one house at a time. The event is joint hosted with Transition Stroud.
