(P)RECAST

Location: Copenhagen Contemporary, Refshaleøen

Period: July 1 – October 30

The (P)recast pavilion challenges conventional attitudes towards precast concrete in sustainable, equitable urban development.

As Denmark faces a wave of demolitions targeting post-war social housing, the (P)recast pavilion is taking a stand against the perception of these buildings as outdated and unattractive. (P)recast showcases innovative use of precast concrete elements, a construction system that has dominated the Danish industry since the 1950s.

The (P)recast research project explores the potential of reusing building components from structures built in Denmark from the 1950s onwards. With these buildings far from reaching their technical lifespan, the team questions whether their components can be reused in new construction, reducing resource consumption and could help Denmark meet its Paris Climate Agreement commitments. An innovative approach, with few references, making the pavilion the first of its kind in Denmark to showcase the reuse of unaltered precast concrete elements.

The concrete elements have been harvested in various demolitions in the metropolitan area of Copenhagen carried out by Tscherning & Søndergaard. The timber used to build the frames are harvested from Jagtvej 169 in the Østerbro borough of Copenhagen and is over 150 years old, however still fit to lift the heavy concrete.

Continously through the research project,  the outcome will be shared with social housing corporations and municipalities across Denmark, empowering them to implement the reuse of precast concrete elements as soon as possible.

The partnership highlights industry-wide collaborative research within the methods and future of reuse of precast concrete elements.

“This pavilion showcases the demolition techniques necessary to implement full-scale reuse of precast concrete elements. The pavilion exhibits the elements whole, and without alteration to illuminate the fragility and aesthetics they have undressed. The pavilion structure is constructed with solely reused building materials, all of which are harvested in the metropolitan area of Copenhagen and is designed for disassembly such that the elements will return to use after the exhibition.”

AFTERLIFE

After ended exhibition period, the pavilion will be disassembled and moved to a different location for further research.

OTHER PAVILIONS

Poetic Daylight

Daylight gives us an understanding of where we are in the world and of the spaces, we find ourselves in every day. The ‘Poetic Daylight’ pavilion, unfolds the spatial qualities of daylight, where the perceptual, aesthetic and poetic potential of daylight can be experienced in a series of spaces.

The Raft

A sensory structure landing on one of Copenhagen canal’s floating platforms, aiming at offering visitors a direct and playful sensorial experience with the water.

13 Climate Action

From 4 to 1 Planet

How do we reduce climate impact from residential buildings to a fourth of the current level without compromising on attractivity and liveability?

Find three different answers to this question in our three pavilions, developed by next generations architects.

Bricks in Common

The brick pavilion ‘Bricks in Common’ brings our attention to this double bind: brick has a potentially long lifespan – it is, however, also a very energy-consuming material to produce. If we want brick to play a larger part of the sustainable development, we need further innovation, development, and more design for disassembly.

12 Responsible Consumption and Production

Living Places Copenhagen

Living Places Copenhagen – the first seven prototypes of the concept, show how we can develop sustainable buildings with a three times lower CO2 footprint and a first-class indoor climate. The concept holds the lowest CO2 emissions in Denmark, demonstrating that we do not have to wait for future technology to build more sustainably

Feed Back

Different lenses on food systems. The pavilion uses virtual spatial design to guide the audience through an exhibition that explores the content of the publication in a gallery-like experience. Users take part of the exhibit space by using their own mobile devices through virtual reality features.

Bio-centre

Architects Without Border’s pavilion is an interpretation of one of their actual development projects, the “Bio-Centre”. Through basic sanitary functions, a bio-center provides crucial services in a densely packed slum – while creating a social focal point.
