ENERGY has become a powerful topic in the architectural debate on sustainable building. It is taking a prominent position next to reuse, CO2 emissions, reductions on waste materials and other environmental impacts. Current trends in addressing these issues tend to focus on imposing approaches, in which reducing, minimizing, restricting and preventing seem to be the buzz-words.

This competition seeks to investigate the inherent characteristics of one material, concrete, in relation to ENERGY. It asks to evaluate those properties of concrete that make it a relevant and versatile material for ‘energy-aware’ applications. It aims to fully pursue the potential of core properties like mass, volume, surface textures, mixtures and hybrids, in acting on current needs and ambitions.  

The 5th Concrete Design Competition - ENERGY stands for a comprehensive strategy to optimize the relations between the built environment and its users. Production and consumption of energy can be dealt with intelligently when taking into account day and lifetime cycles. Storage and distribution needs to be managed with programmatic varieties in mind. Developing built structures that produce energy is part of a more inclusive approach as well.

ENERGY signifies a powerful presence in an architectural sense. How buildings activate and facilitate their users; how they project vitality to their surroundings in form and material – simply by how architecture is.

This competition aims to maximise the material’s potential in its combined technical, physical and architectural opportunities. Applied mass can be embraced to facilitate ‘formal’ and expressive desires that so far have suffered in richness through strategies of minimizing. Simultaneously mass can be deployed to offer capacity for harvesting and storing warmth and coolness. Required volumes and structures can extend in meaning and use beyond their original task of facilitating program. Surfaces and structures can both be visually enticing and can be optimized to capture, store and transport energy. 

Students are asked to explore and exploit the potential of concrete’s properties with respect to any notion on ENERGY. These can range from issues of vitality, robustness, dynamic behavior and architectural presence to energy production, storage and consumption. Competition entries need to address technical and functional aspects as well as formal and programmatic ones – ideas need to be tested through design proposals to demonstrate their potential convincingly. They will be reviewed on the combination of inventiveness in addressing the competition’s theme and architectural implications.

This competition does not prescribe a specific location or program; participants can choose a context of their own that supports their fascinations and ambitions and that fits an acute presentation of their ideas and solutions. The design proposals may range from objects, furniture and architectural details to housing, landscape interventions, complex buildings, infrastructure and structural systems.

Daan Roosegaarde, NL
artist & architect
Principal Studio Roosegaarde

Artist and architect Daan Roosegaarde (1979) explores the dawn of a new nature that is evolving from technological innovations by creating interactive landscapes that instinctively respond to sound and movement. Roosegaarde’s remarkable works of art function as a documentation of the dynamic relation between architecture, people, and technology. 

His sculptures, such as Dune and Intimacy, are tactile high-tech environments in which viewer and space become one. This connection, established between ideology and technology, results in what Roosegaarde calls “techno-poetry”.

In 2009, Roosegaarde won the Dutch Design Award. He has been the focus of exhibitions at the Tate Modern, the National Museum in Tokyo, the Victoria and Albert Museum in London, and various public spaces in Rotterdam and Hong Kong.

Kasper Guldager Jørgensen, DK
Head of GXN, associate partner 3XN

3XN’s Research department, GXN, is established in order to exploit the possibilities that arise when you apply the latest knowledge and technology. The idea is that the expertise and know-how from the department should be implemented in the work of the office. By using new materials and technologies, 3XN will develop a building culture that positively affects the world in which we live – architecturally and environmentally.

Digitalisation has given designers, engineers and architects new tools to work with. This has led to new design and production methods that can generate a new type of architecture. The natural sciences are also moving fast. Within the fields of biology, chemistry and physics it is today possible to design materials that meet specific needs.

'It's always about connections. The meeting, the touch, there's where it happens.
This is true for people as well as for materials. It will always have my interest.'

Gregor Zimmerman, DE
Civil engineer

In 2007 Dr. Gregor Zimmerman, with his partner Thomas Teichmann, began G.tecz an interdisciplinary company composed of material specialists, structural engineers and laboratory experts working to optimize and develop structural and cement-bonded materials. Their latest research includes nano based particle packing algorithms, calculation of water film thicknesses, finite element methods and the use of SQL databases.

Gregor Zimmerman studied civil engineering in Karlsruhe, Germany,
and completed his Ph.D. at the University of Kassel on the topic of membrane concrete grid shells.

Arjen Habraken, NL
Structural engineer

After more than 10 years working as lead designer and project manager/director at Arup in Amsterdam and taking part in their leadership of the structural group, Arjan Habraken recently started his own firm called SIDstudio – representing Structural Innovative Design. With this firm he want to focus more on the design aspects of structure, always with a strong architectural added value and a high level of integration with other disciplines.

Arjan is fascinated by lightweight structures and their inseparable architectural and structural buildup - how Force, Form and Function come together.  He teaches part-time lightweight structures at the faculty of Architecture, Building and Planning at the Eindhoven University of Technology.
