Text description provided by the architects. Project statement

THE-Studio is both a practical demonstration case which deeply integrates sustainable design strategies with ecological technologies, and an experimental platform for sustainable architecture based on the Moderate Zone in southwest China, aiming to examine whether the detailed design methods and building technologies can truly suit to the local conditions of climate, culture and even economy.

Oriented to the specific project positioning, the design team has developed the multi-system integrated design strategy from the very early design phase to minimize the negative impacts to local ecological system while maximizing the indoor comfort and energy efficiency.

Multi-system integration

The multi-system integration includes three levels: the paralleled construction systems, the integration of vernacular culture with sustainable technology and the BIM platform.

Four building systems are implemented in parallel to accelerate whole construction process thus reducing negative interference to the site. Timber frameworks are employed in the large-space exhibition hall, while the prefab light-steel modules are used to shape functional space at both sides. All these structural components and joints are produced off-site and swiftly assembled on site, leading to a significant saving of time and energy. Sustainable service systems (air through tunnel, biomass heating, PVT system, rainwater collecting, control and monitoring, etc.) are mostly plugged into the cavity of façades, which can save installation time, increase indoor flexibility and provide potential space for additional equipment in future experiments. The modular double-skin façade system is a unique integration of vernacular rattan-weaving craftsmanship with industrial prefabrication technology, highly expressing site-specific characteristics while promoting local traditional industry and economy. BIM is also adopted as integrating platform throughout building’s whole life span, especially for coordination of construction, operation and maintenance phases.

Passive design methods

The passive design methods responding to local climatic factors of natural wind, solar radiation and daylight are further contrived by the design team.

Firstly, the large-space central exhibition hall with extra-raised ventilating skylights can truly act as a venting chimney to promote both wind and thermal pressure ventilations while providing adequate and colorful light for the interior.Secondly, the double-skin façades consisting of double-glazed façade at the first floor and the rattan-weaving double skin at the second floor are typical climate responsive design. The double-glazed façade can adapt to the seasonal and daily changes of the outdoor environment, through different operative modes of vents and windows to reach the expected thermal and ventilation performance. Four module patterns for the rattan-weaving double skin are also developed and arranged according to local solar radiation and wind pressure on each façade through software simulation, aiming to comprehensively integrate environmental performance, structural stability and material durability together.Thirdly, the building also adopts the underground air through tunnel as the passive air-conditioning system, which can largely reduce the energy consumption particularly in summer and winter. Its vertical venting ducts are further integrated in the air cavity of double-skin façade and distributed into the major working places, providing fresh air while creating indoor comfort. Fourthly, the building highly encourages usage of renewable materials such as timber, steel and wheat-straw board and promote the employment of vernacular materials and craftsmanship such as traditional rattan-weaving, blue-stone floor pavage and rubble wall masonry, which can both decrease the carbon footprint during whole life span and create a unique architectural self-expression.

After the building was completed, a series of field measuring and monitoring for thermal, humid, ventilation and luminous environments are carried out and further analyzed. The outcomes verify that detailed design methods and building technologies of THE-Studio at the early design phases were both effective and appropriate during the construction and operation processes, which can be the references to the similar sustainable buildings in the Moderate Zone of southwest China.
