Following five regional competitions, 15 Award-winning projects including the Air Suit - Housing Renovation in Hiroshima, Japan, will now compete in the first global Holcim Awards competition for sustainable construction projects. The global phase of the competition showcases the best entries from more than 1500 submissions from 118 countries, and encourages innovative, future-oriented and tangible approaches within the building and construction industry.Holcim Awards competition goes global » pour en savoir plus (French) » más información (Spanish) » leia mais (Portuguese) » lesen Sie mehr (German) » per saperne di piú (Italian) » 更多详情 (Chinese) »
Third prize of USD 25,000 went to an urban housing renovation project to create a building envelope “air suit” in Hiroshima, Japan, by architect Kazuhide Doi of Hiroshima.
Ashok B Lall said that the Air Suit project showed a highly transferable and context sensitive approach and provided a solution to extending building life that is beneficial on both an economic and ecological level. “More than merely a cosmetic alteration, this technique of renovation assures that the living quality of the city is enhanced at the same time as the life expectancy of its buildings is increased,” he said.Full media release – Holcim Awards 2005 for Asia Pacific » 更多详情 (Chinese) »
This project offers a persuasive and inventive solution for the revitalization of the existing urban fabric with minimal logistical concerns. The scheme stands out particularly because of the degree of transferability to a number of different building typologies within the chosen context. The proposal skillfully suggests how social reality in the city can be enhanced by a careful and systematic attitude to renovation rather than only insisting on new construction.
A responsible ethical position concerning urban recycling is thereby forwarded that is beneficial on both an ecological and economic level. The use of light materials for the building envelope increases energy efficiency while reducing operating and maintenance costs. Such savings in turn make it possible to offer affordable housing to a broad range of society, including those who are most vulnerable. More than merely a cosmetic alteration, this technique of renovation assures that the living quality of the city is enhanced at the same time as the life expectancy of its buildings is increased. This solution offers a cost-effective measure to reactivating the urban environment that is at once context sensitive and socially stimulating, proving that the reuse of surviving urban structures need not be programmatically limited or aesthetically disappointing.See more
This project from Japan – entitled Air Suit – is representative of a large number of entries addressing façade construction. In this case, a new enclosure for an existing structure, dealing with strategies of how to potentially improve the energy performance of existing buildings, provides not only a novel approach to the design of high-yield envelopes, but also pushes the envelope in terms of aesthetics. The solution offers a sensitive strategy for dealing with building stock already in place.Download project entry poster (PDF, 4.41 MB) »
