A prototype house was completed in mid-2005, after which it was tested and exhibited for 5 years, attracting more than 5,000 visitors. Testing indicated that the energy efficiency of the house was effective, and energy consumption was only 30% compared to conventional designs. During the 5-year period, some elements of the house were further modified to improve efficiency.
Acknowledgement prizes went to a public utilities project in China, and two housing projects in China and India. In presenting the prizes, Tongji University Dean of Architecture and Planning, and member of the regional Holcim Awards jury, Wu Zhiqiang (China), said that all three projects may well prove to be pioneers in sustainable construction. “The projects showed innovative approaches to ethical, energy consumption and stakeholder engagement, and could equally be applied in other locations,” he said.Full media release – Holcim Awards 2005 for Asia Pacific » 更多详情 (Chinese) »
The overall strength of the project lies in its experimental disposition toward the design of mass-developed, small-scale residential buildings. The authors actively engage the increasing demand for affordable housing in China.
Although the units are quite compact, they nonetheless offer spatial variety as well as a diversity of environmentally-friendly qualities. The ethical concern is straightforwardly addressed as one of providing for communal interconnectivity within a setting that achieves zero energy consumption in a year due to active and passive solar collectors, natural ventilation, ceiling fans, as well as the utilization of earth heat.
Another significant achievement of the project is the implementation of sustainable state-of-the-art technologies for mass-production and demonstrating their adaptability to local skills and social needs. Given the degree of complexity of crossing “generic” production techniques of the building industry with socio-cultural particularities, this project presents a technically competent architectural solution that is just as aesthetically accomplished as it is pragmatically considered.See more
The SRIBS zero-energy link house is commissioned and supported by the Shanghai Research Institute of Building Sciences (SRIBS) as an experimental design for mass developed small-scale residential buildings in Shanghai and its neighboring regions. Due to the increasing housing demand for the middle class families in China, multistory apartments and residential towers cannot meet their demands anymore.
The project develops a link house idea that the buildings are close to nature, with short building width. Each house unit has three stories, and a floor area of 268 square meters (including 50 square meters of basement). The whole building achieves zero-energy consumption in a year. Active and passive solar collection manners are integrated in the design. An atrium is arranged in the center of the house, supplying daylight and enhancing natural ventilation for the deep areas and forming an interior garden. There are windows with automatic outer-shade on the top of the atrium. A section design with half story staggered between front and rear, stairs and light well arranged in the center of house will benefit communication and indoors traffic from different functional areas, providing uninterrupted space for family life.
Insulation in the outer envelope has been improved and there is a major emphasis on the air-tightness. Natural ventilation, ceiling fans and solar control will be adopted so as to reduce the energy consumption from the air conditioning system. Underground energy sources will be used to heat and cool the house in winter and summer. Solar hot water and photovoltaic system will potentially be installed as well. Controlled by the Building Management System, the heating and cooling demands and ventilation are monitored to ensure the indoor air quality and thermal comfort. Rain water and waste water are collected and will be reused for toilet flushing, irrigating plants and treated waste water can be used for evaporative cooling to reduce temperature. Building earth is used as insulation in some parts of the building.Download project entry poster (PDF, 2.46 MB) »See more
Our website search engine covers the web pages including project descriptions and expert profiles, PDFs, images and videos on the LafargeHolcim Foundation website. To improve your search results, here are some tips:
Our search defaults to term-pairing AND. If you search sustainable construction - then the search engine will look for any items containing sustainable AND construction
photovoltaic OR solar
Looks for either word
(clay OR mud) AND (school OR university)
Combine alternative terms for more specific searching
Excludes a term from results, automatically ANDs other terms listed
Use quotation marks to search for a specific phrase or combination
Asterisk (*) matches any word or phrase - so archit* will find architect, architecture, architectural as well as architrave
