Building code airtightness and moisture management
Over several years, Jesse Clarke, M.AIRAH, has worked to improve building standards in Australia with a focus on updating codes and standards to deliver international best-practice building envelopes that are healthy, durable and energy efficient.
In 2015, Clarke proposed that Standards Australia adopt the AS/NZS ISO 9972 standard allowing the determination of air permeability of buildings using the fan pressurisation (or blower door) method. In 2019, he successfully lobbied for the inclusion of a verification method in the residential section of the National Construction Code (NCC) to include an airtightness metric of 10m3
In the recent NCC 2022 update, Clarke successfully lobbied for extension of vapour permeability in building envelopes to further temperate climate regions of Australia. He was also instrumental in the development of AIRAH DA07, which is now a code verification pathway driving innovation in airtight building envelop assemblies that will not trap water, create condensation or mould.
