In order to support building engineering physicists in practice, we must develop new centres in universities and new funding mechanisms to support original and applied research into building energy performance. The dissemination of real world building performance information capable of being benchmarked, rather than marketing misinformation will not just inform future low carbon building designs, but also allow for the development of robust national policy. We must value and reward work by academics in broad multi- discipline fields of design and research and promote knowledge transfer to industry through partnerships and mass publication
