Detailed energy audit

Developed program to reduce energy use


  • Identify opportunities to reduce energy consumption.
  • Improve internal comfort condition for the occupants of Cuthbert House.

“As a Diocese and the Church of England we are really focused on reducing our carbon footprint and ensuring that all the money we spend is done in the most efficient way. So looking at our use of energy and how we can reduce it is really important to us. We asked Sustain to help us with this by undertaking an energy audit, the results of which are now being used to structure our thinking, decisions and future plans around energy use. We are delighted with the work they have done.”- Andrew Thurston - Diocesan Secretary for the Diocese of Durham
