Ian is an independent Building Performance Researcher, specialising in the testing and monitoring of buildings to evaluate the energy performance, indoor environmental quality, and comfort. He is routinely involved in field-based building performance research programmes. The outcomes of his research projects often help inform building standards.

Ian has been a long-standing partner of the AECOM-led technical team appointed to support the UK Government (now the Building Safety Regulator, part of HSE) and, separately, the Welsh Government, in developing revisions to Parts F and L of the Building Regulations for England and Wales, respectively. Since 2008, Ian has provided a leading technical role in the revisions to Approved Document F and the building fabric specifications for Approved Document L, including airtightness standards. More recently, Ian has developed formal guidance for the Future Homes Standard, intended to reduce the performance gap and to improve ventilation standards during the retrofitting of existing homes.
