About

fourwalls is an independent building performance company founded by Ian Mawditt. We are based in Bristol, but operate nationally, working with with people, both householders and businesses, to help you to improve both the comfort and the use of energy in your building. We do this either by working with the construction chain in delivering quality construction, or by working with occupants to help them to better understand how to optimise their built surroundings.

fourwalls work with individuals, organisations, government and their agencies, and offer support and knowledge that is needed to help understand and improve energy use in buildings

We do this through:

  • Providing technical expertise, based upon a broad-range of experience in the field of building performance
  • Discovering insights in buildings and related energy issues, and develop strategies to help improve energy performance
  • Developing tools to help close the performance gap
  • Help organisations and individuals to realise their building’s long-term potential
  • Feedback to stakeholders involved with the building’s design and delivery to ensure lessons are learned.

We can help you to:

  • Save energy
  • Target long-term improvements
  • Improve occupant comfort
  • Reduce costs

fourwalls are pleased to be an associate of the National Energy Foundation, and members of the Good Homes Alliance and the Passivhaus Trust.
