Part 1 - Ian Mawditt
With the consultation out now for the Future Homes Standard and some revisions to guidance on Part F (ventilation) in the UK, what better time to talk to the person behind many of the changes we have seen in guidance over the last few years?
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.
We speak about standards, their role in addressing the performance gap and improving outcomes, what he sees in his research and much more.
