New energy architecture development, which is under the idea of green low carbon, is a subject attracting all the countries’ attention at present.2013 Solar Decathlon, which Beijing Jiaotong University participated in, is co-held by the United States Department of Energy and National Energy Administration of China. It is a solar energy architectural scientific competition that takes global university as participating unit, which is called “World Exposition of solar energy architecture”. It takes 2 years’ efforts for our university’s team to enter the finals. By building for test in campus and field installation assessment competition, displaying technology research and development and designing innovation achievement of new energy architecture along with other 20 global famous universities. Our entry i-Yard 1.0 generated 270 kilowatt hour and used 120 kilowatt hour, getting the first prize in energy balance.
The design creativity of i-Yard 1.0 originates from combination of contemporary philosophy of life, traditional living space and modern scientific methods. The starting point of designing is not only satisfying contemporary needs of market, but also to create kind of house product which leads consumption demand.
Although having the spatial characteristics of Chinese traditional architecture, iYard uses the modern scientific method at the same time to make a perfect integration of intelligence, individuality, imagination and industrialization. The introduction of concept of smart home provides user a humanized and individual life. Internet of things brings one-click interaction of human and architecture, which make i-Yard become smart house and provide technology platform for solar energy technology application at the same time.
With rapid development of urbanization at present, courtyard culture of Chinese housing tradition is onthe wane because of high land consolidation. Contemporary lifestyle requires courtyard space as a new carrier.
Architecture spatial variability—the change of courtyard is led by variability of dining room. The change of coefficient of architectural formalization makes it possible to use solar energy passively. Setting a variable courtyard space in the architecture.
Setting intelligent“wake-up switch” of the whole architecture in an accessible height to feet in entrance. When the master of the house comes back( especially at night), he can wake up the whole architecture by a lightly kick.
APP terminal control
All the remote control to the electrical equipment state can be achieved by using graphic monitoring picture in mobile terminal.
On the premise of guaranteeing efficiency of solar-thermal systems, the system components should be considered as a whole with architecture. To improve the structural rationality and guarantee the overall quality of architectural component and system.
Based on the biological environmental designing strategy, considering effective control and rational utilization to solar radiation from physical layout, spatial organization to surface design.
Energy consumption research: In order to maximize energy efficiency, students have completed numerous alternative energy models under the guidance of teachers and instructors to guide key design decisions such as system design, enclosure structure, and equipment size. ·市场定位：iYard针对西北部中小城市高新技术开发区科技人员的两口之家的“微别墅”的定位，即高舒适度和低消费量。
Market Positioning: iYard's positioning as a "micro villa" for a family of two of scientific and technological personnel in the high-tech development zones of small and medium-sized cities in the northwest, namely high comfort and low consumption. In addition, the variable adaptation of iYard's indoor space presents a dynamic change with the change of family size and structure to meet the needs of residents in different periods. For example, when a household changes from a family of two to a family of three, iYard can separate the children's bedroom to meet the needs of the family.
Innovative practice activities: The SD competition gives college students a special opportunity to learn about the most cutting-edge applications of new energy and energy-saving technologies, allowing them to directly participate in world-class competitions and learning, and lay the foundation for becoming industry leaders.
On-campus trial construction: On the morning of June 7, 2013, the "Beijing Jiaotong University Solar Decathlon Launching Ceremony" hosted by the School of Architecture and Art of Beijing Jiaotong University was grandly held at the Xiaoshulin Plaza, South Gate of Beijing Jiaotong University. This ceremony is the beginning of teaching practice combining production, teaching and research, and a good beginning for teaching practice to focus on practice.
Promotional materials: We have designed a series of postcards, micro-chapters, brochures, T-shirts, etc. about iYard, which are presented as souvenirs to other teams and sent to friends who care about iYard from afar, hoping that they will see our design results, and It is given to tourists who visit iYard on the public day, and it is deeply loved by everyone.
As an architect, it is our dream to achieve the design on our own will completely, and to build it by ourselves. As an architectural teacher, it is our dream to lead students from idea, drawing to construction in a competition.
Solar Decathlon takes our 2 years to make our dream come true. Recalling the experience of last two years, from conceiving slogan to submitting the application, from forming a team to selecting the scheme, from production check to negotiating and raising money, from changing drawing to building for test, from designing team uniform to web construction, from safe training to site construction, from interior layout to iYard party. We spent countless nights meditating in front of computer, discussing and arguing with teammates, we also spent countless days to transporting materials and building the house.
Why can 60 teachers and students devote themselves to SD? Because we have the same dream to chaise sunshine. Why can we insist during the past 600 days? Because we all believe sunshine comes after the storm—SUNNY HOME, SUNNY HOPE!
