Lois recently completed her PhD which explores the embodied and life cycle impacts of domestic retrofit from a carbon and energy basis, as well as furthering the understanding of how retrofit life-cycle studies should be framed differently to those of a new-build. Prior to this, she worked in environmental consulting for nearly a decade, during which time she embarked on her own retrofit journey in 2015, converting a Victorian industrial building into a home. She joined the AECB at this time, and was later part of the first cohort of the original AECB Carbonlite Retrofit course. This was pivotal in establishing the best approach for her retrofit, supported by her background in environmental sciences which provided a firm foundation for understanding building physics. Lois completed her Passive House Consultant qualification in late 2020. Her transition back into academia for her PhD enabled a deep exploration of retrofit; her findings are critical to ensuring that robust decisions can be made with respect to retrofit and decarbonisation, and are published in a series of peer-reviewed articles. Her work in this area is ongoing.

Lois is a Trustee with the Lune Valley Community Land Trust, who with their housing association partner, developed 20 affordable Passive House homes for shared-ownership and rental to local people, completed in 2023. Lois sits on the Board, and was part of the design team and was involved in community engagement and developing scheme layout options, through to detailed design and appointing contractors.
