    Lessons from AHMM’s Stirling Prize-winning Burntwood School building performance study

    Lessons from AHMM’s Stirling Prize-winning Burntwood School building performance study

    Episode 27. We continue our focus on building performance; AHMM sustainability lead Craig Robertson shares important lessons from a building performance study of 2015 Stirling Prize-winning Burntwood School in southwest London. It is still much too rare for architects – and clients – to transparently share post-occupancy data, especially when it flags up a significant performance gap, so kudos to AHMM for sharing this study with us.

    In the case of Burntwood School, heating loads were nine times the design prediction, while electricity loads were four times as much. Shocking as this may sound, it is not unusual. Craig explains why and what we need to do about it. A key premise of the study was to investigate the relationship between energy performance and indoor environmental quality. These must be looked at in tandem. Our conversation with Craig reveals, in practice, the many building performance issues we discussed in our last episode with Judit Kimpian.

    Judit Kimpian on why building performance studies are crucial for net zero

    Judit Kimpian on why building performance studies are crucial for net zero

    Episode 26. A year after publication, Judit Kimpian and Hattie Hartman revisit key messages from the book they co-authored with Sofie Pelsmakers. Judit explains why building performance studies de-risk the construction process and help ensure that what was designed actually gets built and operates as intended. She explains why it is so important to stay with a project during a one-to-three-year ‘landing’ period after completion, to ensure proper commissioning, monitor both energy and indoor environmental quality, and talk to occupants.


    Plus, you can WIN a copy of Energy|People|Buildings by J. Kimpian, H. Hartman and S. Pelsmakers (RIBA Publishing 2021). We have three copies to give away – details here.

    AKT II’s Hanif Kara on CLT virtue signalling, concrete innovations and Bloomberg’s embodied carbon

    AKT II’s Hanif Kara on CLT virtue signalling, concrete innovations and Bloomberg’s embodied carbon

    Episode 25. AJ Climate Champions with Hattie Hartman. In this episode, we hear from structural engineer Hanif Kara who is working with leading architects on projects across the globe for ambitious clients with resources to deliver sustainable outcomes, including Google, Apple and British Land. Recent projects include Grafton’s Stirling-Prize winning Town House in Kingston, Grafton’s Marshall Building at the LSE, Foster + Partners' Bloomberg building and the new Google headquarters currently on site at King’s Cross with Bjarke Ingels and Thomas Heatherwick.

    In contrast with most of our guests so far, Hanif is not a Climate Champion from way back, but we’re delighted to have him on the pod because he is at the forefront of what is being delivered on the ground now and his design-led approach is pushing best practice. In this episode, he advocates reverse-engineering as a forensic method that utilises complex computational methods to retrofit and extending existing buildings.

    Bangladeshi architect Marina Tabassum on why the climate crisis is not a north-south problem

    Bangladeshi architect Marina Tabassum on why the climate crisis is not a north-south problem

    Episode 24. AJ Climate Champions with Hattie Hartman. In this episode, Soane Medal (2021) winner Tabassum describes her approach as distilling the essence of vernacular buildings into contemporary architecture


    Working on the front line of climate change in the Ganges delta, Tabassum is developing flat pack bamboo homes to bolster marginal communities devastated by seasonal flooding.  ‘How relevant are we as a profession if we just cater our services to one per cent of the people?’, she asks.


    Tabassum was recently short-listed in the London School of Economics’ competition for an academic building at 35 Lincoln’s Inn Fields as part of a team led John McAslan + Partners with Tod Williams/Billie Tsien Architects.

    Philippe Madec on combining sustainable development with Frampton’s critical regionalism

    Philippe Madec on combining sustainable development with Frampton’s critical regionalism

    Episode 23. AJ Climate Champions with Hattie Hartman. In this episode, we continue our focus on France, speaking to one of the country’s leading practitioners of ecological architecture. Over four decades, Philippe Madec has combined practice, teaching and writing. He has built extensively across France: housing, public buildings, and many urban design and masterplanning projects which feature abundant green spaces. He also explains why he is no longer interested in Passivhaus.

    How France is pioneering contemporary architecture built from straw, hemp and thatch

    Episode 22. AJ Climate Champions with Hattie Hartman. New year, new horizons: Climate Champions is going abroad in search of fresh approaches to ecological architecture. This week we continue talking to French architect and natural materials expert Dominique Gauzin-Müller, who explains why hybrid use of materials is the way forward. We also speak to French structural engineer and ACAN member Frédéric Bourgeon about France’s new embodied carbon regulations.

Stuff that matters today & tomorrow

I’m not an architect but this is intensely interesting. It tells me about topics that matter now and in the future with respect to the environment in general e.g. natural landscape, energy use etc.. It’s not about aesthetic look of so called ideal example buildings.
