welcome to fourwalls

We are a multi-disciplinary practice that specialises in building performance evaluation. The work we do spans from single project technical support through to industry-wide research.

Our goals are: to effect positive change in building practices and standards; to help close the performance gap between the predicted and actual energy use; and to help ensure the built environment is a healthy place for people.
