We’re proud to share that our Building Physicist and Research Fellow at Energy House Labs, Grant Henshaw, recently featured on Episode 6 of Create & Construct: The Podcast by Tobermore.
In conversation with Michelle McNeill and co-guest Tom Greening, Grant explores some of the most pressing challenges facing the built environment today, including performance gaps, retrofitting, and the future of construction materials.
Drawing on work at Energy House Labs, Grant discusses how we test how homes actually perform compared to their design intent. This includes evaluating fabric heat loss, airtightness, and building services within controlled environmental conditions, helping to better understand real world performance.
With around 80% of the homes that will exist in 2050 already built, improving existing housing stock is just as critical as delivering high performing new homes. The conversation highlights why robust measurement and verification are essential to ensuring retrofit interventions genuinely deliver on their promises.
The episode also touches on the role of IEA EBC Annex 94, which is focused on validating diagnostic tools to confirm that energy efficiency improvements achieve measurable outcomes.
This is a valuable listen for anyone working in housebuilding, building performance, and energy efficiency, offering insight into how the industry is evolving to meet future demands.
