March 30, 2012

On March 29, 2012, the results of the 3d Global Holcim Awards 2012 in the sphere of technological, environmental, socio-economic and cultural issues affecting building and construction were summed up.

A secondary school project in Burkina Faso (Gando) designed by Diébédo Francis Kéré won the gold prize. Passive cooling during oppressive summer heat creates an indoor climate conducive to learning by routing air through
subterranean tubes, planting vegetation, stack-effect air currents, and using double-skin roofs and façades.

The silver prize went to a project that transforms an eroded landscape within the Paraisópolis favela in São Paulo (Brazil) into a productive zone and dynamic public space. The project led by architects Alfredo Brillembourg and Hubert Klumpner includes a terraced public space with areas for urban agriculture, a water management system, a public amphitheater, a music school, a concert hall, sports facilities, public
spaces and transport infrastructure.

An urban plan for transforming an under-utilized arm of the River Spree in the historic part of Berlin (Germany) into a natural 745m-long “swimming pool” won the bronze prize. The project includes a 1.8ha reed bed natural reserve with sub-surface sand bed filters to purify the water was developed by a team led by architects Jan and Tim Edler.

For the first time, all 53 prize-winning projects from the five regional Holcim Awards 2011 competed for additional prizes based on their contributions to innovative building materials. Special attention was paid to their contributions to innovative building materials and construction technologies in the context of sustainable construction.

The Holcim Innovation 1st prize went to Fabio Gramazio & Matthias Kohler for a construction technology using molds that combine existing processes and materials in a new way to fabricate cast-on-site concrete structures with reusable and digitally-fabricated wax formwork.
The 2nd prize was awarded to a collaborative project by German Barkow Leibinger Architects, Schlaich Bergermann und Partner, TU Berlin and Transsolar Energietechnik. Their low-cost apartments project in Hamburg uses innovative techniques and materials including prefabricated lightweight-concrete elements with recycled foamed glass as aggregate.

A team of students from the AA School of Architecture in London (UK) won the 3rd prize for a research project on an efficient cast concrete fabrication system for geometrically complex building elements.

The six global prizes will be presented to the winners in individual events and in close cooperation with the respective Holcim Group companies in the course of the next half year.
