Architects must re-educate themselves on timber sourcing
Thursday Oct 12, 2023
Thursday Oct 12, 2023
Episode 42. AJ Climate Champions with Hattie Hartman and George Morgan. Montreal-based architect and systems thinker Scott Francisco explains why architects must educate themselves to understand the nuances of timber sourcing.
Francisco believes that greater use of timber in construction in coming decades will be essential to meet our climate targets. This in turn means an increase in plantation forestry, but this can be achieved without compromising biodiversity.
He also explains why it’s crucial for designers to have a holistic understanding of the timber supply chain. While timber certification is important, relying on certification alone is not enough. He outlines the range of factors that impact the carbon footprint of timber and how to understand different sourcing strategies.
Architects can play an important role in specifying ecological timber by asking the right questions and educating themselves to understand that specifying a species and a grade is not enough. In some instances, particularly on smaller projects, architects can construct a timber value chain for a particular building.

Architype’s Ann-Marie Fallon: ‘Net Zero has almost lost its meaning’
Wednesday Sep 27, 2023
Wednesday Sep 27, 2023
Episode 41. AJ Climate Champions with Hattie Hartman and George Morgan. In this episode, AJ100 Sustainability Champion and Architype associate director Ann-Marie Fallon discusses her belief that delivering net zero is not just technical – understanding how people use buildings and their role in the community is crucial.
We also hear about Architype’s success in influencing policy changes in Scotland, including a Passivhaus equivalence standard for all new housing. Fallon describes the growing community of architectural practices in Scotland pushing for more sustainable outcomes.
Fallon has been instrumental in developing a ‘blended’ approach to retrofit through a nuanced study of the city of Edinburgh’s estate of 300 buildings with a wide variety of building typologies from different eras. This holistic approach involves everything from exploring whether the activities in a particular building can be consolidated and intensified to the nitty gritty of updating mechanical plant.

‘We apologise for designing buildings that exploit the planet’
Wednesday Jul 26, 2023
Wednesday Jul 26, 2023
Bonus episode. AJ Climate Champions with Hattie Hartman. During an Obel Award panel at the UIA conference in Copenhagen, Heringer seized the opportunity to ask the global audience for ‘forgiveness’ on behalf of architects of the global north.
‘I'm sorry for creating this … ideal of an architecture that was supposed to bring us a comfortable, safe and happy and healthy life, when in fact, it was just exploiting the planet and adding to social injustice,’ she said.
Winner of four important awards since our last interview in episode 6, Anna explains how earthen architecture is gaining traction and describes her ongoing work in Ghana and at the St Michael Campus for Sustainability in Traunstein, Germany.

Chinese architect Xu Tiantian on revitalising rural villages
Wednesday Dec 14, 2022
Wednesday Dec 14, 2022
Episode 40. AJ Climate Champions with Hattie Hartman. In this episode, we explore the global phenomenon of shrinking villages in the countryside, hearing about a remarkable series of interventions in southeastern China by DnA_Design, a small Beijing practice.
Xu advocates a role change for architects in both rural and urban contexts. Architects should no longer accept a commission as given, but take the initiative and evaluate a project’s regional context to make a proposal that is unique and rooted in its place.
In less than a decade, Xu and her team have built more than 20 projects that vary widely in programme and materiality: a tofu factory, a museum, performance spaces and a sugar factory. These projects have attracted new residents back to formerly dilapidated villages by creating jobs and a sense of purpose in these forgotten places.

Episode 38. AJ Climate Champions with Hattie Hartman. Slade, head of historic building climate change adaptation at Historic England, explains why insulation is the area of highest risk.
As a conservation-accredited building surveyor with deep interests in both the natural and built environment, Slade explains the role of Historic England as a statutory consultee in planning, in provision of technical guidance and training, and in research to confront upcoming climate challenges. In this episode, she argues that sustainability and conservation are ‘well-matched’ to deliver change on the ground.
Slade also details the range of guidance and webinars available from Historic England, as well as the current research agenda which includes ‘hazard mapping’ of regional risks. This involves granular mapping of overheating, flooding, slope collapse, shrink-swell capacity and storm exposure under different emissions scenarios and their implications for the built environment.

Adapting conservation area guidance for climate emergency
Wednesday Nov 16, 2022
Wednesday Nov 16, 2022
Episode 38. AJ Climate Champions with Hattie Hartman.In our second episode exploring how sustainability impacts heritage buildings, we speak to Procter-Rihl Architects’ Chris Procter, lead author of ACAN’s Climate Emergency Conservation Area Toolkit – England. Chris explains how conservation areas can streamline the consent process by developing a pattern book approach to building elements.
Chris’ detailed audit of Islington’s Cross Street Conservation Area found that two-thirds of existing single-glazed windows could be suitable for double or triple-glazing, 44% of solid external walls could be wrapped in external wall insulation and over 30% of roofs could be fitted with solar panels.
Chris also delves into the sensitive topic of window replacement, arguing that if existing windows do not conform to the original window pattern of a building, they should qualify for upgrading. He advocates development of a pattern book of details, complete with approved manufacturers, to simplify the consent process for building owners, relieve planners’ workloads, and speed up retrofit. Chris argues that this should be done locally based on specific building types.

Wednesday Nov 02, 2022
Episode 37. AJ Climate Champions with Hattie Hartman. 5th Studio co-founder Oliver Smith shares his radical approach to upgrading listed buildings. He talks about the practice’s radical retrofit of New Court at Trinity College, Cambridge. Completed in 2016, New Court remains a trailblazing project because it pioneered an ambitious sustainability agenda in a Grade I-listed building using a nuanced approach that balanced heritage concerns with upgrading thermal and energy performance and internal comfort.

Educators Sofie Pelsmakers and Cíaran Malik on teaching climate literate design
Wednesday Oct 19, 2022
Wednesday Oct 19, 2022
Episode 36. AJ Climate Champions with Hattie Hartman. In this episode, Pelsmakers argues that teaching values must be at the heart of architectural education. She believes students are bombarded with too much technical information on sustainability and that a strong grounding in architectural ethics is essential in order to apply technical knowledge for the best possible built environment and social equity outcomes. This approach requires not only new curriculum content, but a shift from master-apprentice to more democratic and inclusive peer-to-peer learning.
Sharing insights from having taught recently in seven different schools of architecture, structural engineer and educator Cíaran Malik notes that curriculum reform has not kept pace with students’ demands for change and that retrofit remains a minority topic. Malik argues that once students develop an intuitive understanding, grounded in evidence, they can begin to experiment with results that are both ‘beautiful and exciting.’

Why architectural education needs radical reform
Wednesday Sep 21, 2022
Wednesday Sep 21, 2022
Episode 34. AJ Climate Champions with Hattie Hartman. Glasgow climate activist Scott McAulay and ACAN’s Rosie Murphy advocate for a curriculum which empowers students as changemakers.
McAulay, founder of the virtual Anthropocene Architecture School, argues that the answer to every brief should not be a new building. Architects must rethink their role as stewards of the built environment rather than designers, and students should be taught to scrutinise a brief in its larger context. Perhaps a vacant or underutilised building nearby can be transformed to meet a client’s needs.
