A mechanical engineer, Diane’s interest in building physics arose a number of years ago with the realisation that our existing buildings are crucial to reducing our environmental impact. After the completion of her MSc at the Centre of Alternative Technology and academic publications in the field of ventilation in traditional dwellings, she continues to increase our level of understanding through a combination of research and project work with clients.  Working as Green Footsteps (greenfootsteps.co.uk), Diane undertakes airtightness testing (iATS accredited), infrared thermography and energy calculations for new buildings and those about to undergo retrofits. She is a Passivhaus Consultant, Passivhaus Tradesperson and a Level 2 Building Thermographer.
