Student accommodation provider, urbanist, has achieved Passivhaus standard accreditation for its purpose-built student accommodation (PBSA) development in Battersea.
The certification from the Passivhaus Institut makes it the largest Passivhaus building in the UK and the eighth largest in the world.
Developed by a project team also featuring Allford Hall Monaghan Morris (AHMM), Mace, and Henriksen Studio; the development is situated close to the iconic Battersea Power Station and provides energy-efficient accommodation for 853 students.
This achievement also establishes it as the largest student dormitory/university building designed to Passivhaus standards in Europe, and the third largest in the world after UTSC in Canada and the Cornell Tower in New York.
With a treated floor area of over 17,964sq m, the building was designed by RIBA Stirling Prize-winning architects, AHMM, with specialist Passivhaus design consultancy from Henriksen Studio.
It was sustainably constructed by Mace using its innovative low-carbon, off-site technology.
Situated at the northern edge of the Battersea Design and Tech Quarter masterplan, the four-block development steps up in height from 11 to 19 storeys, serving as a gateway into the site.
And its glazed terracotta façades in a vibrant colour palette of red, green and blue reflect the site’s industrial heritage.
Opened to students last September, urbanest Battersea features ensuite and studio accommodation and boasts a cinema room, gym, and roof terraces with views across the city.
Rendering conventional heating systems unnecessary, the low-energy construction concept makes efficient use of the sun, internal heat sources, and mechanical ventilation with heat recovery. This allows for space heating and cooling related energy savings of up to 90% compared with typical buildings and over 75% compared to average new builds.
Having undergone stringent airtightness testing, the building was also designed with great attention to all relevant construction details, reducing thermal bridges as much as possible.
High-performance opaque and transparent façade elements have been used in order to assure a comfortable interior environment. And the building was also delivered to BREEAM 2018 Outstanding standard.
Since 2008, urbanest has opened nine PBSA properties in central London, including King’s Cross, St. Pancras, Victoria, Vauxhall, and Tower Bridge.
This is the firm’s first Passivhaus scheme, but it is already on its way to bringing forward a second scheme on an even larger scale in Canary Wharf.
urbanest Canary Wharf is set to be the largest residential Passivhaus development in the world upon completion in 2026.
Angus Kearin, head of development at urbanist, said: “We’re delighted that urbanest Battersea has now achieved Passivhaus certification to become the largest Passivhaus building in the UK, setting the standard for sustainable student accommodation.
“From the start we wanted our Battersea development to be an exemplar for future projects, not only in London, but in cities all over the world that need to respond to the net zero challenge.
“This is just the beginning of our Passivhaus journey and we look forward to continuing our work with the Passivhaus Insititute to achieve accreditation at urbanest Canary Wharf and all further urbanest schemes going forward.”
Simon Allford, co-founder at Allford Hall Monaghan Morris, added: “urbanest Battersea stands as an industry-leading example of compelling architecture and sustainable construction, achieved through the combined expertise of urbanest, AHMM, Henriksen Studio, and Mace.
“Passivhaus certification highlights what’s possible through collaborative ambition and a commitment to excellence; we are immensely proud of the result.”
And Dragos Arnautu, building certifier at Passivhaus Institut, said: “urbanest Battersea exemplifies the benefits and innovation of Passivhaus design applied to student living.
“Delivering unmatched energy efficiency, Passivhaus buildings maintain consistent indoor temperatures and superior air quality, reducing the need for heating and cooling systems.
“Students benefit from a thermally-stable space conducive to focus and relaxation, while the integration of renewable energy sources aligns with broader climate goals.
“This building also stands out for prioritising community and modern amenities, offering a holistic lifestyle that balances sustainability with urban convenience.”
