Liam has worked in PassivHaus and EnerPhit construction for 8 years, beginning his career on Lancaster Co-Housing where he became responsible for ensuring all houses surpassed the 0.6A/ch requirement.
He moved to Erneley Close in Manchester, a retrofit of 32 social housing maisonettes, where he worked with the main contractor and project managers to install and test the airtight envelope. To achieve this they also trained two other site operatives onsite and became responsible for liaising with trades to ensure the airtight fabric remained undamaged. He took on responsibility for making sure the insulation was carried out to the required standard.
He has worked as a main contractor on a variety of projects including a Victorian end-of-terrace in Lancaster which met new-build PassivHaus standard and an EnerPHit project near Manchester that passed the airtest at 0.67 a/ch.
He specialises in refurbishment projects and has worked on many as an ‘air-tightness champion’, not just installing the airtight layer but also training site operatives in how to work on an airtight, super-insulated build.
He is a trustee of the AECB (Association of Environment Conscious Builders) and believes strongly that this style of building needs to become the mainstream, as this is the only way the existing UK housing stock and new-build at any scale can play its part in combating climate change.
