We are on a mission to demystify sustainable design and make it effortless; collectively we can combat the climate and biodiversity crisis. Our whole life design approach reduces carbon emissions over the lifecycle of a building and creates healthier, happier environments.
We have been pioneers in sustainable design since the practice was founded. Did you know we are working on the UK’s largest Passivhaus development and first certified hospital? And we created an award-winning open-source tool for architects, designers, and clients to achieve zero carbon emissions at every stage in a building lifecycle? There’s also a fair chance that we contributed to the industry-led sustainability guidelines that you currently refer to. We can make sure that your project makes a real contribution to resolving our climate and biodiversity crisis for future generations through a curated range of services and evidence-based design. We constantly strive to do better and are strong advocates of Post Occupancy Evaluation to close the feedback loop.
Newcastle University Urban Sciences Building
The Urban Sciences Building is a real ‘living’ laboratory – a place where academic research is used to generate and test real-life solutions that benefit people, businesses, and the city. The university’s aspirational post occupation goals, to deliver the highest standards of sustainability throughout the building’s operational lifetime, were such that they couldn’t be sufficiently recognised with a BREEAM ‘Outstanding’ rating.
So, together with engineers Buro Happold, we developed a bespoke sustainability framework for the building, designed specifically to drive sustainability beyond BREEAM with an auditable approach to developing targets for design, construction, and occupation, proposing vigorous reporting techniques and innovative delivery strategies to ensure targets were met.
The building’s sustainable design features include: a smart tech demand and response energy system with on-site storage; thousands of sensors providing real-time, online environmental data for each space; a bio-dome on the building roof that uses waste heat, water and carbon dioxide produced by the labs below to grow food for the café, and experimental areas of DC electrical power supply for workspace. The team undertook a comprehensive, post-occupancy evaluation to improve the building’s performance and the University are now developing the BIM information into a ‘digital twin’ to progress further internal research.
Nottingham Trent University Arts Building
The requirement for a net zero carbon building was enshrined in Nottingham Trent University’s original brief for their new arts department. We led regular dedicated carbon workshops during the first design stage, in which we agreed to target net zero whole life carbon, the targets to be applied to the project and a strategy for achieving this. The workshops also facilitated easy sharing of design data between consultants and enabled us to set up a process to track operational, embodied, and whole life carbon through the various design stages.
The net zero carbon pathway developed with the University was a key part of the planning material presented at public consultation and the commitment continued into the development of the tender information. Embodied carbon information was written into the specification and shared with the main contractor and their team, with an aspirational carbon target defined in the documentation. Client actions in relation to the net zero carbon performance of the completed building were also documented. The project is currently on site.
1 Golden Lane
We have been leading a multi-disciplinary team in the design and delivery of a complex refurbishment project into commercial workspace. The project features a complicated set of conditions including listed façade and internal features, with a proposed new build roof extension and lateral extension.
Alongside the architectural role, we have been leading the embodied and whole life carbon analysis workstream. This has included early-stage scheme benchmarking and material advice, stage by stage analysis, data for planning and visualisations of the carbon reductions and net zero carbon pathway that will contribute to marketing material for the development.
A key part of the design investigation has been an emphasis on the circular economy and the re-use of as much found material on-site as possible, balanced with the constraints of warranties and budget. We have undertaken detailed façade comparisons together with the façade engineer and contractor to specify the materials, construction process and life cycle replacement guidance.
The case study explores the façade shading options by using solar irradiation mapping as a tool. The key challenge was to find the suitable shading option that provides solar protection during summer period to avoid overheating, whilst maintaining good amounts of daylight access.
Here and Now
The ‘Now’ building, completed as the first phase of the ‘Here and Now’ project, is a refurbishment of two existing office buildings in Reading, which provides a range of spaces in response to the increasing demand for sustainable work environments. The existing building used glass and metal extensively, leaving no clear identity or purpose. Facades looked corporate and defensive and had no relationship with the surroundings, that are rich in plants and trees.
The refurbished spaces reintroduce nature through extensive internal planting and connections between internal and external spaces. Amenity spaces are provided at these points to create a shared community.
Assura Net Zero Design Guide
A leading primary healthcare developer, Assura is on a mission to lead on securing a sustainable future – caring for the health of people and our planet. We coordinated a multi-disciplinary team including Civic Engineers and Atelier 10 in the production of a comprehensive Net Zero Carbon design guide.
Assura needed the guide to help the Executive Board effort to push for organisational improvements in the development and operation of their built projects at a strategic level, as well as to provide information to the development team for implementation on live projects.
The information provided included a summary of the qualities that a net zero carbon building should have and an action list for each member of a multi-disciplinary team at each RIBA Stage. A template environmental metrics tracker was developed for use on all projects as part of the initial briefing process, and to record the agreed position for any contractors or building managers coming on board later. More detailed information on low carbon design, relevant to all stages of the design and members of the team, was provided, which linked to each work stage guide and included guidance on post completion actions, building monitoring and setting up the BIM model for asset management. We will be involved with updating the guide as Assura use it on more projects, gain feedback and the evolution of Net Zero Carbon continues in the built environment.
We are the Passivhaus Designer for the third phase of the Agar Grove estate regeneration project, working for Camden and also the contractor Hill Partnerships. We have been working alongside Max Fordham who as Passivhaus Consultant is responsible for the PHPP planning tool, thermal bridge modelling and liaison with the Passivhaus certifier, regarding documentation and evidencing.
We have detailed the external envelope without contractor design portion, initially focused on window brackets as the largest unknown thermal bridge, and developed details that ensured balustrades and window reveals could be supported by either brickwork and their support angles, or in some instances, thermally broken structure. Air tightness at a block level has been simplified by creating air tight party walls – redundant once complete – but key to enable more efficient testing. At a detail level the geometry and number of multiple tapes used on individual junctions has been significantly simplified from previous phases.
This mixed use development delivers a beautiful new primary school and nursery alongside 89 high quality homes.
From the outset, both the client and design team wanted to create a school that both pupils and the community could be proud of; the BREEAM approach inspired the team to go above and beyond the initial aspiration. Far from being a hindrance, the mixed brief supported more efficient and innovative design solutions and enabled the building to meet Outstanding at design stage, rather than its initial target of Excellent. The project team’s core principles were to retain the quality of the design outcome within the constrained viability of the scheme and ensure it carried through to construction. The focus on health and wellbeing and the BREEAM methodology has been key.
In 2018, Tiger Way won a BREEAM award for the best public project at design stage.
We worked in partnership with the UCL Institute for Environmental Design and Engineering (IEDE), through their Engineering Doctorate program, to create the award-winning Hawkins\Brown: Emission Reduction Tool, which works by measuring the volume of all materials tagged in the Revit model. It then applies embodied carbon data to that material, broken down into life cycle stages (product, construction, use stage and end of life) in line with BS EN 15978:2011.
H\B:ERT V1 (V2.1.5) aligns with the RICS and RIBA guidance and currently uses the Circular Ecology ICE database, but can use alternative data where available.
H\B:ERT is compatible with Revit 2018, 2019, 2020, 2021 and 2022. Download the new updated toolkit with installer below.
H\B:ERT V2 has evolved from the free version through the creation of a web-based data collection and visualisation platform, that allows the data from Revit to be more clearly represented. The tool enables the filtering of results, comparisons between various design options for both embodied and whole life carbon, as well as a breakdown of building elements and life cycle stages aligned with the RICS Methodology 2017 and GLA WLC reporting. We have also added a component library which allows the quick comparison of different build-ups to drive good decision making from the earliest stages of creating an outline material palette.
