Data centre architecture and innovation explored in London exhibition

‘Power House: the architecture of data centres’ is a new London exhibition exploring the design of these often overlooked, but increasingly commonplace infrastructure buildings

‘Power House: the architecture of data centres’ is a London exhibition (3 November 2021 – 28 February 2022) about a critical and increasingly commonplace type of building, albeit one that remains out of sight for the vast majority of the world’s population. The data centre is now utterly integral to modern society, emerging as a crucial piece of infrastructure and industrial architecture that serves up everything from official secrets to selfies. As computing shifts decisively into the cloud, we are effectively untethered from hardware thanks to our reliance on these colossal structures and data centre architecture. For the end user, it all remains very abstract; we have no idea where our data is stored, let alone what kind of building houses the servers required to host it. 

Data centre architecture explored

Retrofitted Oil Rigs by Arup

Retrofitted oil rigs by Arup. Created especially for the exhibition, this vision of an offshore cluster of data centres proposes re-using existing oil rigs, with cooling coming from the sea and the wind. According to the architects, the structures would be ‘circular, modular and sustainable, giving a new life to these abandoned sea giants'&

Contemporary data centre architecture comprises colossal structures, shaped by the need to provide space for thousands of pieces of equipment, together with the security, cooling, and redundancy measures required for smooth, seamless operation. These buildings are also extremely energy intensive; one of the stark statistics cited by the exhibition curators is that ‘a single Bitcoin transaction has the equivalent impact of watching 91,624 hours of YouTube’. They add that the internet generates around one billion tonnes of greenhouse gas emissions every year, thanks in part to the rapid spread of these new architectural archetypes. 

Depending on its scale, a data centre can draw up to a hundred times more power than a comparatively sized office building, which is why ‘lights out’ centres are becoming more popular; remote, dark facilities that can run without any human intervention except for maintenance, to make for more sustainable architecture.

Gak Chuncheon Project by Kengo Kuma and DMP, Gangwon Province, South Korea. Completed in 2013, this data centre for Naver was designed by Kengo Kuma with DMP. A low-rise structure, it sits in the foothills of Mount Gubong and has been designed to allow for natural cooling

Clearly, we’re going to need more data centres, not fewer, so their visual and environmental impact is of paramount importance. ‘Power House’, on show at the Roca London Gallery, considers the evolving physical design of these decidedly non-human spaces. Curated by author and Walllpaper* contributor Clare Dowdy, the exhibition also has a focus on London’s data centres, overseen by Dezeen's Tom Ravenscroft. In big cities, these structures are often ‘hidden in plain sight’, with a corresponding absence of aesthetics. All too often, they’re the epitome of business park blandness, whether it’s for reasons of security or sustainability. 

There’s no such coyness in many of the exhibits, which include completed structures, projects underway and conceptual ideas. ‘Data centres power modern life and yet they're rarely considered as pieces of architecture,’ says Dowdy. ‘As they mushroom across the globe, it's time we thought of data centres as a peculiar, and peculiarly challenging, new building typology.’

Qianhai Information Building by Schneider + Schumacher, Shenzhen, China

Qianhai Information Building by Schneider + Schumacher, Shenzhen, China. Designed by the German studio Schneider + Schumacher, the Qianhai Information Building in Shenzhen is the first high-rise data centre. Due for completion in 2023, the 16-storey tower has a roof garden for employees and a windowless façade bearing a binary representation of pi, designed to shimmer in the wind. At ground level, public facilities help integrate the structure into the cityscape

AM4 data centre by Benthem Crouwel Architects, Amsterdam

AM4 data centre by Benthem Crouwel Architects, Amsterdam. Built for American data giant Equinix as part of its portfolio of over 200 data centres around the world, AM4 is located in Amsterdam. Completed in 2017, the 12-storey building was designed by Benthem Crouwel as a modular structure that could eventually be repurposed. In addition, heat generated by the equipment is shared with other buildings on its Science Park site
