Overall Winner of the 7th Active House Symposium – I-yard 2.0
On 16 and 17 October 2019 the Active House Alliance held its 7th symposium, where experts from all over the world interested in the sustainable construction exchanged ideas and best practices. This is the first time that this international event has come to North America.
During the event, the Active House Label Awards have been organized, where projects submitted to Active House have been evaluated and awarded in different categories by a professional jury composed of international building experts. The Jury Committee was composed of Professor Marco Imperadori, Politecnico di Milano (Italy), Eileen Meyer, architect (Italy), Shaun Joffe, executive director, Great Gulf (Canada), Arianna Brambilla, Lecturer, Sydney University (Australia), Wolfram Trinius, Civil Engineer, Ingenieubüro Trinius, Hamburg (Germany), and Peder Vejsig Pedersen, Board member and Renewable Energy specialist at European Green Cities (Denmark).
The house I-yard 2.0, China has been the Overall winner of the Awards. The house has been created by a team of architects: Junjie Li, Haishan Xia, Chunxiang Lin, Jie Huang, Wanlin Wang, Lei Shi, Changdai Han, Yichun Jin, Xiaotong Liu, Xinxing Chen, Jiayi Wang, Danyang Zhang, Shujian Dai, Min Li.
The building has a series of basics design parameter on daylight, thermal comfort and ventilation. The indoor day lighting regulation system mainly uses the dual-channel control method to reach the control of wireless physical switch and intelligent app through a variety of wireless connection devices. It adjusts the lighting brightness, light color temperature, one-button control mode and wake up stress lamp at night to meet the lighting needs of the elderly under different use environments.
In terms of active design, the floor heating system of the building uses the radiant film technology of electric heating and the stone floor of tourmaline + calcite which can improve the heat transfer efficiency and absorb indoor particles to improve indoor air quality. The air conditioning system uses the efficient and energy-saving photovoltaic direct-drive VRF air conditioning system. It centrally arranges the air inlet and outlet pipes according to the shortest path to reach the rapid indoor cooling in summer.
The core of the building uses a variable atrium. On the one hand, the platform is made of aerogel glass which has a good heat preservation and insulation effect; on the other hand, the rise and fall of the atrium platform can achieve a good ventilation adjustment and temperature adjustment by changing the upper and lower positions
The exterior wall of the building uses self-designed light-weight steel composite wall board and external hanging insulation board to improve the overall insulation effect of the building. At the same time, the field filling method is used to solve the problem of discontinuity of insulation of traditional modular prefabricated buildings.
The building uses a membrane filtered reclaimed water recycling system that collects water from the kitchen, bath and shower as well as rainwater, which is treated for daily watering and electric vehicle cleaning to reduce water consumption.
In awarding the prize the Jury Committee mentioned:
“A very interesting and inspiring compact building dedicated to co-housing where Active House strategies and radar drove to an elegant and simple solution but full of small details which create harmony and originality. Active House is clearly a vision beyond 2020 and it is a pleasure that this vision spans around different parts of the world and in this case the winner is a project in China that could inspire many other ones in the future.”
