Studio: Diana Dina on AJ Climate Champions podcast 

Diana Dina, our head of sustainability and regenerative design is interviewed by Hattie Harman in the fourth episode of the AJ’s Climate Champion podcast series. She shares her insights on how to be a changemaker in a large architecture practice, and how Haworth Tompkins is looking to collaborate with other practices on the climate emergency.

We are signatories of Architects Declare, and these are the actions we are taking in response to those commitments

Research: Could professionals within the Built ​Environment be held to account in the future? 

Associate Hannah Constantine completed her MSc in Construction Law and Dispute Resolution at Kings College London at the end of 2020.

Her final year dissertation aimed to proposition whether a new class of negligence is emerging within the Law of Tort, in response to the growing urgency surrounding climate change, and whether professionals within the Built Environment could be held to account in the future for their contribution, both passively and proactively, asking the question of whether we are doing enough.

Project: Refurbishment vs Demolition 

We are committed to retaining and refurbishing existing buildings wherever this is a feasible and suitable solution, as part of our AD declaration.

Recently we worked with our structural engineers, Heyne Tillett Steel, to assess and compare the carbon emissions between two options: retain, refurbish and extend vs demolish and rebuild in one of our projects for a London local authority.

Research: Post-Occupancy Evaluation - Liverpool Everyman Theatre 

As co-founders of the Architects Declare Climate and Biodiversity Emergency movement (AD) Haworth Tompkins have acknowledged the significant impact buildings have on climate and on global ecosystems. By signing up to the AD declaration points HT have committed to assess and re-think our approach to design.

One important aspect of this is the decision to carry out in-house light-touch Post Occupancy Evaluation (POE) studies aiming to identify strengths of completed projects, possible areas for improvement, and further learning for the design team, alongside our clients and consultants.

The Everyman Theatre in Liverpool was used as a test case to see how the Practice could embed light-touch Post Occupancy Evaluation (POE)/Building Performance In-Use reporting across our office portfolio. The Everyman was chosen because it uses an innovative assisted natural ventilation system and the design team were keen to understand how well it was working, to inform the design of similar performing spaces.

Studio: HT Architect Simon Ricketts on WUFI 

WUFI is an acronym that stands for Wärme-und Feuchtetransport instationär, which translates in English to 'Transient Heat and Moisture Transport'. It’s an advanced moisture modelling programme designed by the Fraunhoefer Institute in Germany, enabling highly accurate building physics decision-making. Haworth Tompkins are keen to preserve existing buildings and upgrade them as much as possible, not only to keep our important historic heritage, but also to reduce the environmental impact of projects.

Project: BREEAM Outstanding for Kingston School of Art 

Haworth Tompkins’ major refurbishment of Kingston University’s Mill Street Building for Kingston School of Art has been awarded BREEAM Outstanding, with a score of 86.2%.

BREEAM provided a structure for benchmarking and assessing the sustainability aims with the team paying attention to measures reducing energy use and CO2. BREEAM was supplemented by Haworth Tompkins’ own sustainability toolkit, with further priorities incorporated relating to wellbeing, adaptability and resilience.

Studio: Our Carbon Footprint Report 2019 

The current climate and biodiversity emergency highlighted by the Architects Declare movement – now celebrating its 1 year anniversary - has prompted individuals and organisations to become aware and take responsibility for their impact on the environment.

As founding signatories of the AD declaration, HT have started to calculate their office carbon foot­print with the aim to find ways to reduce it, and then to offset the remaining carbon emissions in a way that is meaningful for the environment.

Research: Sustainable and regenerative design: reading list, research and design tools 

Here are our suggestions for a broad reading and research list - including articles, books, databases, tools and guides to help understand the problems and the solutions. Please click for link:

Studio: Passive House Training 

In a bid to adopt more regenerative design principles, and to design architecture and urbanism that goes beyond the standard of net zero carbon in use, a third of our architects are receiving specialist training this week, focusing on Passive House.

Advocacy: Future Homes Part L consultation 

Haworth Tompkins are supporting LETI’s response to the Part L consultation, focusing on the need for:

- improved fabric performance requirements
- use of metered energy (kWh/m2yr) as principal metric for performance evaluation
- retaining the power of Local Authorities to set carbon reduction targets beyond Building Regulations

Advocacy: The London Energy Transformation Initiative 

Haworth Tompkins are an organisational supporter of the London Energy Transformation Initiative (LETI), a network of over 250 built environment professionals who are working together to put London on the path to a Zero Carbon future. LETI have lobbied for policy change and their recommendations have been included in emerging London Policy. These recommendations include energy use disclosure, use of updated carbon factors and whole life carbon assessments for referable schemes.

Event: Rethinking the way we design and work 

‘Rethinking the way we design and work’ was the theme of a day held by Haworth Tompkins focusing on the Architects Declare emergency goals and commitments. We acknowledge that addressing the AD goals will require an important change in our design process, and in our studio, and this was an excellent opportunity to get everyone in the office involved in the discussion.

Project: The Den - a low-carbon portable, community theatre 

Minimum environmental impact and social equity are at the heart of the design that composes this super-lightweight theatre.

Advocacy: Architects Declare 

The twin crises of climate breakdown and biodiversity loss are the most serious issue of our time. Buildings and construction play a major part, accounting for nearly 40% of energy-related carbon dioxide (CO2) emissions whilst also having a significant impact on our natural habitats.

Event: Exploring Doughnut Economics 

Steve Tompkins and Beatie Blakemore recently attended a workshop at Hawkwood College led by Kate Raworth and Juliet Davenport, looking at how businesses can meet the needs of people within the means of the planet. The workshop explored the principles of ‘Doughnut Economics’ – a concept developed by Kate Raworth that has been widely influential amongst sustainable development thinkers, progressive businesses and political activists. Juliet Davenport is founder and CEO of renewable energy supplier Good Energy.

Project: Offsite construction for Osco Homes 

Transportation associated with construction site activities, material delivery and waste removal account to just under 40% of total energy use within the construction industry. At Baycliff Road our houses are constructed off site as separate wall, floor and roof cassettes and then assembled on site in typically around 12 hours per house. The construction period on site is much shorter than a traditionally built project and relies on considerably fewer deliveries to site and vehicle movements.

Studio: HT appoints Head of Sustainability & Regenerative Design 

Diana Dina has recently joined Haworth Tompkins to help develop and lead the practice’s sustainability and regenerative design strategy, balancing practical in-house support/training, external advocacy and independent research. Diana will work closely with the Directors, the Associates and the HT Sustainability Team to focus on progressing a vision and strategy for sustainable and regenerative design and practice including the education of staff, developing and reporting on sustainability metrics, maintaining sustainability resources, and greening the practice operations.
