Since Reyner Banham, the status of pipes, ducts and other environmental control equipments has been brought to a significant stage, and even a crucial one in face of current environmental disasters and energy crisis, such as the great smog spreading all over China. Thus the current paradiam based on the classical modernism theories and principles no longer sees its sustainablity and recently great attention has been paid onto those invisible agents such as air, water, heat and so on to explore new paradiam that incorporates physical environmental elements from the very beginning of the design process and let them induce the final form of the design. This project is just based on this idea.

Although Reyner Banham laid the foundation of raising the awareness of architects to attach importants to the space for environmental control equipments, he went to the extreme futuristic end of the totally artificial space-capsule-liked space where everything is under precise control by highly sophisticated technology, which indicates that, in simple words, architecture can be an insulated system. Others like Dean Hawkes and Kiel Moe have different opinions that architecture is never a insulated system, the aim of design is actually finding a way to dissipate energy in the most powerful way possible, which I personally more agree on.

For me, the key to create a well tempered environment lies not in what kind of technology we should use or how we use it, but in whether this technology, low or advanced, can sychronize with other important factors such as function, aesthetics, or even social relations among people. Therefore in this small community center project, I firstly analysed the wind enviroment of the site located in Shanghai, then optimized the prototype of wind tower according to the basic rules of wind flow effect. In addition to that, I arranged the program according to their thermodynamic properties to create temperature gradient to trigger convection effect, together with rain water collection and circulation as well as air cooling equipments to creat a synergetic public space that integrated natural elements, program and people's activity. Though due to the limitation of hard core thermodynamic knowledges, the results of the simulation was not solid enough when it came to the quantative stage, the qualitative analysis were satisfying enough for the morphological optimization.

The site is right on the edge of a historical residential area that has been existed for nearly one century at the centre of Shanghai.

On the site there's already a food market, but the space quality as a major public centre of the surroudding area is far from satisfying. Therefore the market needs to be rebuild to create more pleasant experiences for the residents nearby.

The excessive using of ventilation machines and tubes on the south facade showed an exteme unfriendly gesture to the residents living behind it, consuming huge amount of energy for ventilation at the same time. This existing disadvantage became the starting point of the design concept—Using the building as the device for ventilation.

FLOOR PLANS

Summer Strong Wind Scenario On windy days in summer, due to the sloping shape of the roof, negative pressure will form on the leeward side, thus taking stable wind current from up high into the wind tower.

Summer Weak Wind Scenario On weak wind days, the interior pool and greenery will cool down the air temperature on the ground level through evaperation, while activities happening upstairs will increase the air temperature, this temperature difference will cause chimney effect to draw the air upward. Besides, with the help of cooling equipment mounted in the wind tower, exterior air will also be sucked in.

Winter Wind Scenario On cold winter days, the slope roof will guide the wind flow to pass the building quickly, reducing the cold wind effect. The wind tower will be enclosed to act as a thermo mass to absorb heat from the sun and release heat to interior space

VERTICAL TERMINAL 2015 CTBUH STUDENT COMPETITION GROUP WORK(4 PEOPLE) Contribution: Group leader, analytical drawings, overall strategy design, part of digital model making, rendering Advisor: WANG Zhendong FALL 2015

As one of the busiest metropolitans in the world, New York city enjoys the reputation of high-efficient transportation system. But after site study of our group, we found that , as the density increases, there have been explicit indications of decline in the connectivity and integration among major airports, urban railway transport system and subway system, which is the short slab of the whole system and calls for more intensive and efficient transportation infrastructure to be built. However, the extreme density makes it almost impossible to build new or expand existing infrastructure horizontally. On the other hand, the peninsula of Manhattan lies on the layer of hard rock which makes it much easier and more financially efficient to build the infrastructure UPWARD than DOWNWARD. Our site is just besides the Grand Central Terminal, the busiest transportation hub in New York. By 2050, a number of more than three times the total population of Boston commuters will pass by the GCT everyday. In order to satisfy the huge future demand of commuting and enhancing the connectivity among the airports, subway and long distance commuting, we proposed a vertical terminal.

This terminal integrates airport transport, railway, and ground public transport into one complicated system. By introducing airport express trains, new Silver Line and LIRR line upward, it presents an unprecedented transportation experience. For commute passengers, the primary issue is efficiency. In vertical terminal, passengers can transfer from airport express to shuttle train Silver Line or commute line LIRR, just by walking to the diagonal side of the building, which is a less than 1 min walk distance on the same floor level. This innovative vertical infrastructure makes transferring and waiting experience consistent with the New York cityâ&#x20AC;&#x2122;s urban space.

Various transportation systems of different levels draw people up into this infrastructure building. Vertical Terminal is the real sense full-time functional skyscraper. From the underground connection with GCT, to the city plaza, from the revolving driveway for city bus and taxi, to the three-dimensional parking of rental cars, from transfer floors for airport arrival and subways, to departure floors, these systems all-together propose a compositional high-rise building archetype, bringing a new perspective to high rise.

FLUENT CITY 2014 VERTICAL CITY ASIA COMPETITION GROUP WORK(6 PEOPLE) Contribution: Group leader, analytical drawings, overall public system design, pysical model of the whole site, one detailed physical model, 1/6 of final hand drawing Advisor: WANG Zhendong Summer 2014 Mumbai is one of the cities with the highest population density all over the world. Under the background of high population density and land shortage, it grows rapidly and vertically. Besides, the urgent need of modernization adds more complicacy to its urban planning and construction, and has caused latent danger for the city’s future development. Urban space, social structure and even the relationship with the traditional culture in Mumbai are all broken down, thus seem unsuitable to its regional characteristics.

Through the on-site investigation, we choose to follow the idea of “renovate with both preservation and development”. But we face three challenges.

The first one lies between city and nature. The north-south railway isolates the city from the eastern water front. So we propose a green dune for people to walk through while connect city with nature gently. It will also act as landscape infrastructure for Mumbai.

The second one lies in the infrastructure. There are a lot of breaking points and dead ends in the city. We propose a backbone includes transportation, industry, greenery and other infrastructures. All these kinetic energy will be handled on the backbone to interact with nature.

Third is that the communities become isolated islands during the urban development. Therefore, we propose fluent city for Mumbai 2050. To this end, we suggest to build fluent, kinetic boundaries to replenish infrastructure, improve living condition and connect public space, while preserving the existing life styles within the communities.

As a result, we create a fluent system. This system lies in traditional Indian concept of Aakash (void) which contains four subsystems of Green Infrastructure, Amenity, Transportation and Industry.

According to the characteristics of the climate and urban life in Mumbai, we consider three levels of adaptive designs in the fluent system: water space, wind path, flexible space. We expect that our fluent city will make it possible for everyone to have access to fresh air, clean water, job opportunity, better services and above all, the lost Indian livability traditions.

MUMBAI REALITY: STATIC CITY vs KINETIC CITY "Today in urban India there exist two cities—the static and kinetic—two completely different worlds that cohabit the same urban space. The static city is represented through its architecture and by monuments built in permanent materials. The kinetic city that occupies interstitial space is the city of motion—the kuttcha city, built of temporary material. In the kinetic city architecture is no longer the spectacle of the city; rather, processions and festivals form its spectacle and memory, and the very expression of the city is temporal in nature, in constant flux."

LOST OF TRADITION: THE PHILOSOPHY OF AKASHA Our spatial strategy oringined from a concept called AKASHA, which means the basis and essence of all things in the material world, the "upper sky" or 'space' in Hinduism. The metaphoric influence of Akasha can be found in spatial design at all scales in traditional Indian architecture. However, during the rapid development of metropolitan Mumbai, this tradition of "the valuable void"(Akasha) has been forgotten and has given way to massive, insulated, completely artificitial entities, the connection between city and nature, people and architectue has been lost.

SITE

BLOCKS ON SITE vs FLUENT STRATEGIES Three major problems were spotted on site, following by three corresponding strategies we proposed.

First of all, the north-south railway isolates the city from the eastern water front, an artificial green slope over the railways and highways, using backfill soil from the brown land along the east coast was created to reconnect the city with the east coast. Secondly, the Acharya Donde Marg, the most important road on site which not only embeds historical significants but also bears major role in west-east connections, has various existing breaking points and will soon reach its limitation infrastructure wise. Therefore we proposed a multi-layered backbone integrating transportation, industry, amenity, greenery, water, energy etc. to interact with people and nature. Lastly, to breakthrough the current isolation situations of the living communities on site, we extended branches from the backbone into the boundaries of the communities as a catalyse surface to activate communications among those communities.

PRESERVATION

DEVELOPMENT

Step1: Focus on the major road Acharya Donde Marg

Step1: Starting point of the new development: the railway running from north to south

Step2: Keep the relatively stable area such as the government chawls,hospitals,historical buildings,slums.

Step2: Connect the trans-harbor link to the present freeway,the metro to the railway,making the Sewri station a new traffic hub.The bridge goes underground as not to damage the small scale community environment.

Step3: For the preserved area,we increase the building density along the boundary to provide sufficient living space and infrastructure,thus releasing the inner pressure.

Step4: Furthermore,we introduce more base levels to connect the dotted renewal,so that the kinetic energy inside the communities can be gathered and transported.

Step3: The green slope decomposes the volume of the bridge,and people can get access to the sea over the slope.

Step4: As for the sewri station,a mixed development including Offices,commercial and residential area is encouraged to make it a new city center.

PRESERVATION vs NEW DEVELOPMENT The reality on site is ultimately complicated in terms of history, demographic, ownership,architectural typologies. The future transportation plan made by the government around existing railway station add more complexity to it. Different strategies towards different sub-areas were adopted to balance the complicated situations.

FLUENT CITY Putting together the three fluent strategies, we proposed our fluent city, a modern interpretation of Akasha, where natural elements and social interactions constantly flow. It is a kinetic space synergizing people with fresh air, clean water, better service, job opportunity and above all, the lost Indian traditions.

CITY LAB, CITY MAKER URBAN DESIGN STUDIO IN TECHNICAL UNIVERSITY OF BERLIN GROUP WORK(4 PEOPLE) Contribution: Analytical drawings, overall strategy design, major axonometrical drawings, all digital model making, part of physical model making Advisor: Raoul Bunschoten, Liss c. Werner Spring 2016

The CITY LAB pilot project is a mechanism that introduces mass-producible components that can be variably attached and combined to produce from a module to a cluster to a neighborhood. The Production Line is taking place in the premises of the former Tempelhof Airport, with the Hangar 7 functioning as the Manufacturing Department for the construction of the Modular Building Kit and the Hangar 6 as the Showroom Department for the control and exhibition of the modules. With the appropriate Infrastructure systems and the Urban Ecology principles applied as well to the Tempelhof production facilities as to each of the three out of sixty selected sites in Berlin, a new housing system typology is being created that fits the vision of the Conscious City.

This project forms a different identity for every site, according to our program and their correspondence to each theme. The target group is refugee students and families in need for housing, forming our scope of needs to be addressed and covered by our system, as following: housing, start-up establishment, internship collaborations, research development, study networks and recreation possibilities.

These needs were translated into spaces and were distributed to the sites accordingly:Quedlinburger Strasse, situated within the network of the biggest educational institutes in Berlin, functions as an ‘educational hub’, an extension of the existing educational framework, promoting the students’ research and development. Karl Marx Allee, situated at the heart of the existing Berlin co-working spaces’ network connects to the ‘start-up point’ network, since our site works as an incubator for young entrepreneurship. Alte Jacob Strasse, part of a generally housing neighbourhood, mostly satisfies the need for accommodation, thus acting as a ‘green living hub’, raising, at the same time, their environmental awareness.

The CITY LAB system proposes strategies of the development of education and research opportunities, along with building ‘green’ awareness among its citizens.It improves the overall living quality, by adopting new green technologies and implements systems with which energy is produced through natural treatment sources and is being re-used for the viability of the whole system itself.

Thus, an entirely new system is created, as an example of the positive impact of the new technologies and the cost and energy efficiency of modular housing solutions.

PRODUCTION LINE IN TEMPELHOF AIRPORT The former Tempelhof airport building is like a theatre set in search for a strong play and its characters. It is one of the largest buildings in Europe. It is a space of complex layers of history and contemporary city-life. Since closing in 2008, the building, which is strictly listed, has been at the core of debates regarding future usage, by making it the head quarter for design and production of CITY LAB project, the building is brought to new life as a showcase for historical renovation, digital fabrication and humanistic concern.

"was fertig ist, was niemanden mehr berührt, ist am ende(Finishing is the end when no one touches any more)" ----Behnisch Günter Giving a fnished spatial masterplan often means the end of something and people get stuck in structures. In this urban design housing project in Pankow, Berlin, we don’t want that. We called our design "Jam Session" because we don‘t want to deliver a product. A jam session is a PROCESS in which different impulses come together and lead to an open result. In our cpontext, we only provide a solid framework and the opportunity for a great and open process.

On the other hand, with this project, we would like to touch on how communication between different interest groups can better occur and bring balanced result that fit to all actors involved in the development. We developed card games assisting us about how systems communicate and act with or against each other in order to pursue and attain their goals. In this process, several possible development plans, including ownership, finance model, action plan were compared and a housing alliance model, which rooted from the rich tradition of cooperative housing in Berlin were developed.

A power shift from monopolic owner to multiple smaller private owners or groups is the key in our model. There will be a central committee consists of representatives from various interest groups to organize the formation of housing alliances and development. General public who share same interest can apply to form housing alliances freely as long as permitted by the committee. The development will start with public buildings on selected spots if the developers of these buildings are willing to reimburse part of the profit on affordable housing as the tradeoff.

With the democratic founding of alliance and the flexible master plan, diversity and order could be achieve at the same time, and ultimately, adequate participation of actors involved could be realized to reach multi-win situation during the development.

WIND DANCER DIGITAL FUTURE WORKSHOP IN TONGJI UNIVERSITY GROUP WORK(5 PEOPLE) Contribution: Team leader, analytical drawings, overall strategy design, part of digital model making, part of physical model making, part of Arduino code writing Advisor: Philip Feng Yuan Summer 2017

The energy issue in architecture has been brought into spot light again in face of severing environmental pollution and energy crisis. A new design paradigm is needed, which takes environmental performance and energy flow into consideration at the early stage of design at the same time retrieves the autonomy of architecture discipline.

This workshop project is conducted right under such background and focus on design strategies of wind-driven architectural design as part of the environmental performance based architecture design.

The direct response of architectural forms to energy is their dynamic response to natural elements including wind, light and heat. The increasing focus on buildingsâ&#x20AC;&#x2122; environmental performance calls for a change in architectural design paradigm, which creates comfortable dwelling environment on the pragmatic level, generates new form on the aesthetic level and regards architecture as an open system like metabolism that generate dynamic feedback to the ambient on a philosophic level. This epistemological change expedites environmental performance driven design, which doesnâ&#x20AC;&#x2122;t satisfy the standards and requirements of the performance through post design suppliment but completes the generation of form through correlating environmental parameters with morphological parameter in the early design stage.

Wind tunnel and CFD software has been used to make design optimization in the engineering field for a long time, but the workflow cannot be directly applied to design stage due to the heavy consumption of time and money for calculations. Although there are several architect-oriented connecting software in use, the fast real time correlation of form changing and CFD simulation is never fluently realised, which bring us to physical wind tunnel again but combined with mechanical systems controled by Arduino.

In this workshop, we focus on one form changing methods----rotated geometries, trying to find most optimized twisting shape regarding wind environment, in both single building scale and building cluster scale. The form changing is controled by Arduino system, though not as freely as in digital environment, it dramatically reduces the time needed for setting up grids and calculation in CFD software, the result of which is sufficiently informative for architects to make decisions in the early design stage.

RESEARCH CITATION AERODYNAMIC PERFORMANCE OF TWISTING GEOMETRY Existing research have shown that twisting geometries have better aerodynamic performance than rectangular shape, especially in reducing vortex shedding effect. The helical form also embeds aesthetic beauty which makes it appreciable to architects designing novel form of skyscrapers.

EVAPORATIVE COOLING BLOCK MATERIAL RESEARCH PROJECT IN HARVARD GSD GROUP WORK(4 PEOPLE) Contribution: Analytical drawings, overall strategy design, all digital model making, part of physical model making Advisor: Martin Bechthold Fall 2017

There is an argument to be made for the recovery of natural systems in architecture that challenge 20th century notions and modern practices of tight building envelopes and mechanically cooled buildings, regardless of the climate and context in which they are located. With the ubiquity of mechanical air-conditioning and market demand for fully-glazed building facades, the modern approach to architecture and building systems comes with high costs. Architects must consider introducing suitable materials adapted to local climatic conditions to offer innovative and viable solutions to conditioning spaces in and around buildings. By disentombing traditional methods of construction and variable thermal comfort and by enhancing them with contemporary modes of design and fabrication, this project proposes empirical study that suggests a return to designing naturally conditioned spaces to alleviate energy loads on buildings in cooling dominated climates. The results of this iterative process of discovery are the reliable production of lightweight ceramic units forming facades and partitions using minimal amounts of material. These facades are further enriched by performance-based tectonic assemblies that allow for effective thermodynamic characteristics and unique architectural expression.

The use of terracotta assemblies for evaporative cooling is well documented in vernacular construction, contemporary design, and even simple housewares. However, these distinct examples, unique in spatial and temporal conditions, either rely heavily on secondary and tertiary steel and aluminum assemblies, or are simple to the effect that performance metrics are inconsequential or not available. Digital design and fabrication offer new possibilities of combining simple construction techniques with highly programmed material performance.

Ceramics have a long history in art and construction, chosen for durability, workability, recyclability and locallysourced nature. However, ancient casting and extruding techniques limit the high-performance possibilities inherent in ceramic material assemblies. This research presents potentially scalable and transferable construction techniques that combine easily accessible casting fabrication methods with maximized surface area made possible by combining 3D printing technology with traditional slip casting techniques using plaster molds . There is an emphasis on well-established research in direct evaporative cooling (DEC) that closely influences the form and space of the units to be produced.

“THE INSULATED MODERNISM” ---- Kiel Moe We barnacle our buildings with these dx window air conditioning units. This does not exactly inspire the kind of architecture our cities deserve.

LEARN FROM TRADITIONS The use of water to lower the ambient air temperature by way of evaporative cooling is wellknown in vernacular construction. Throughout hot and dry climates around the world, such thermal comfort devices have exist still today in the form of modest pools within courtyard houses. The physics around evaporative cooling which takes advantage of the porosity of terracotta is also well known
