The meaning of r-cells
The project, named R-CELLS, is a solar house prototype with ‘positive energy, full recycling, zero emission’ as the technical goals, aiming at creating ‘a lifetime healthy and sustainable home’. It symbolizes the self-adapting, self-circulating, and self-organizing characteristics of biological cells. By adapting prefabricated and customizable modules, innovative solar building integration technology, and close-to-nature design, it targets a solar energy housing prototype that can be replicated in rural and urban circumstances in North China.
Scheme design concept
在可持续性建筑设计概念和方法上，R-CELLS住宅强调“被动优先，主动优化”的设计原则，创新太阳能建筑集成技术。在被动式太阳能利用方面，借鉴中国传统建筑“反宇向阳”的特点，采用不对称 V 型屋面形式，增加南向得热和采光，最大限度地实现冬季被动式太阳能的利用。同时增加屋面光伏面积，为主动式太阳能的利用提供足够的空间。
In terms of sustainable building design concepts and methods, R-CELLS Residence emphasizes the design principle of "passive priority, active optimization" and innovative solar building integration technology. In terms of passive solar energy utilization, drawing on the characteristics of traditional Chinese architecture "anti-universal to the sun", an asymmetric V-shaped roof is adopted to increase southward heat gain and daylighting, and to maximize the use of passive solar energy in winter. At the same time, increase the roof photovoltaic area to provide enough space for the use of active solar energy.
Variable module combination
In terms of architectural design concepts and methods, R-CELLS residence adopts the design of prefabricated + custom combined modules. Module functions can be combined according to the needs of users, which can adapt to the needs of the entire family's life cycle.
Prototype expansion renderings
The R-CELLS housing prototype can be expanded horizontally and vertically, and can be promoted to urban low-, multi-storey and mid-high-rise residential buildings that are adapted to severe cold and cold climate areas, as well as new-type rural residential buildings in the construction of new rural areas. And through performance simulation optimization and parameterized design methods, the optimization design system of its physical performance, solar energy utilization efficiency, life cycle environmental impact and cost is established to adapt to different environmental and cost conditions.
Overall technical strategy
在总体技术策略上，R-CELLS 住宅强调“正能源、全循环、零排放”的技术概念。正能源即场地能源盈余；全循环即能源与水的内部循环利用，以及建筑材料的可回收；零排放即建筑运行中 CO2 净零排放以及洗浴餐厨生活废水零排放。
In terms of overall technical strategy, R-CELLS Residence emphasizes the technical concept of "positive energy, full cycle, and zero emissions". Positive energy refers to the energy surplus of the site; full cycle refers to the internal recycling of energy and water, and the recyclability of building materials; zero emission refers to the net zero emission of CO2 during the operation of the building and zero discharge of domestic wastewater from bathing, kitchen and kitchen.
Profile technology strategy
The R-CELLS residential prototype uses solar energy as the main source of electrical energy, supplemented by battery packs. On the basis of meeting the needs of daily life, the excess electrical energy can be transmitted to the grid, achieving zero energy consumption in the building and being a "producer and seller" of electrical energy transactions. Reduce the energy cost of users and have higher economic benefits.
Wood structure system
R-CELLS adopts a mixed structural system of heavy wood and balsa wood. The structural frame is heavy-duty glulam made of Douglas fir. The structural wall is composed of SPF balsa wood and SIPs structural insulation board. The structural materials are mainly materials that have low environmental impact or high recycling efficiency, such as wood and metal production and processing, and the physical and chemical carbon emissions including the initial construction, replacement and dismantling stages are small. Use environmentally friendly building materials to achieve the goal of human living health during construction and use.
Building life cycle carbon emissions
According to the R-CELLS energy consumption simulation value, in the next 50 years of the estimated building life, the carbon emissions reduced by building photovoltaic power generation and component recycling will exceed the sum of building carbon emissions and electricity carbon emissions during operation. Achieve negative carbon emissions in the life cycle of buildings, which has high environmental benefits.
R-CELLS is committed to creating a barrier-free environment for people of all ages and the disabled. The design considers the barrier-free path and the spatial scale of wheelchair movement, such as barrier-free kitchens and bathrooms. The indoor white, wood, and gray tones are gentle and comfortable.
Healing landscape design
Incorporate the healing landscape to create a quiet landscape atmosphere for home recuperation, choose plants with medical value, and play the practical value of plants while creating a good visual effect. The indoor green wall has the functions of air purification, microclimate control, carbon reduction and landscape creation.
Adopt the smart construction model, use the building information model, and coordinate the management of all disciplines to achieve full digitalization, and help all disciplines to unify the work platform, so that the overall work operation is more efficient, convenient and precise.
Five functions of the intelligent system
1.Energy management: energy consumption analysis, load forecasting, and dispatching strategies.
2.Environmental regulation: monitoring temperature and humidity, CO2 concentration, PM2.5 concentration, building indoor environment management based on indoor comfort evaluation.
3.Smart home scenarios: household-oriented young people mode, elderly mode, child mode, etc., and function-oriented wake-up mode, away from home mode, sleep mode, etc.
4.Voice interactive control: Intelligent voice controls lighting, air conditioning, smart home, etc.
5.Smart housekeeper: building operation and maintenance reports, energy usage recommendations, preventive maintenance strategies.

2021 年 4 月 21 日上午十点 R-CELLS 建造启动仪式在天津大学建筑西楼顺利举行。我们有幸邀请到了各位专家顾问共计 30余人与Team Tianjin U+师生共同见证开工搭建这一重要节点。
The launch ceremony of R-CELLS construction was successfully held at the West Building of Tianjin University at 10 am on April 21, 2021. We are fortunate to invite a total of more than 30 experts and consultants to witness the start of construction of this important node with the teachers and students of Team Tianjin U+.
随后历时两天两夜15个模块高效吊装运输，如期从西楼“搬家”至崭新的国家会展中心。R-CELLS将于6 月 24 日到 6 月 27 日在国家会展中心首展 GIB 展会与公众见面。最终作品将于 2021 年 9月亮相张家口张北德胜村，进行实际运行并实时测试。
Subsequently, 15 modules were efficiently hoisted and transported in two days and two nights, and they were "moved" from the West Building to the new National Exhibition and Convention Center as scheduled. R-CELLS will meet with the public at the first GIB exhibition at the National Convention and Exhibition Center from June 24th to June 27th. The final work will be unveiled in Desheng Village, Zhangbei, Zhangjiakou in September 2021 for actual operation and real-time testing.
