Guovdageaidnu village: urban design

2019 Europan 15 Competition

Site: Guovdageaidnu, Norway

Site area: 45.5km2

Personal research and design

Northern Europe has always been a mysterious area and rooted with plenty of urban issues due to the topographical and climatic situation. Sami people tends to leave their homeland reaching for better opportunities, and the rest of the local Sami are still struggling with the development of the towns and preservation of their husbandry tradition. Thus, the loss of population and the problem of productivity lead to a stagnant status of the area. How to develop and enhance the productivity, and meanwhile preserve the traditional husbandry is the main task in the development of Guovdageaidnu.

Using the basic combination of farmland and housing as a unit, furtherly develop into a new chessboard model that contains the potential of growing and mode-changing. A sustainable development program could be made according to the chessboard model, in order to bring back the dynamic of the town and using its traditional agriculture base to generate the economy growth.

In the project, buildings surround a common farmland for husbandry/ agriculture, which is autonomous by the residents themselves and as a part of the farmland network that improve the productivity in the whole village. The central farmland view is also penetrating into each of the building and create a dynamic collective community. Buildings are also surrounded by other public farmlands, which will turn into public square or park in the next phase according to the chessboard model

Idle resources

According to the research from European Environment Agency, there are many HNV farmlands in the north Sapmi area, but due to topography and climate situation, only a few used arable land located on the southern part. Therefore large amount of useful resources is left empty and wasteful.

3 stages of productivity in Sapmi town development

In the background of highly segregation, 3 stages of productivity are defined: the 1st stage is like Guovdageaidnu where only husbandry products are produced; the 2nd stage is like Abisko, where tourism and local agriculture tradition combines to create commercial benefits; the 3rd stage is like Tromso, a big city where its own industry and production line are able to produce economic profits and to reach autonomous development.

Guovdageaidnu (NO)

Punctual farmland network

A solution in which housing surrounds farmland could be introduced and a network of farmland connecting with each other is established.

Project program

Chessboard analogy

A surrounded figure/ground relationship is clear and obvious on the chessboard, and two main qualities could be defined in the chessboard model as followed.

The chessboard could regarded as a fractal pattern which could expand unlimited and form a high compatibility grid.

The chessboard model is variable in size and provide different shape of figure/ground relationship. Moreover, different levels of openness/function is compatible and could be applied to the model.

Four basic elements

Four basic elements and their modules are shown on the left. The diagram on the right indicates the relationship between the elements, the further theory and model is developed basing on the relationship of elements.

square

The relationship between farmland and housing in which the farmland provides its own products to the residents and the residents take care of the farmland, is called internalized relationship. When combining with public square, a further level of relationship emerges in the diagram.

The relationship between farmland and public building (school, shop, tourist center, etc.), in which the farmland provides educational, economical and experiential products to the users and visitors, is called externalized relationship. Internalized relationship could be blent into externalized relationship to create a complex system.

Existing housing

Grid setting

Phase1.1: infrastructure

Position new farmland according to the location of the existing housing and adding new infrastructure (street)

Phase1.2: Repeat

Repeating same procedure as phase1.1

Phase2.1: functionalized

New building (housing+amenities) is built according to the new farmland (private), public-oriented farmland is also added along the street

Phase2.2: Repeat

Repeating same procedure as phase2.1

Phase3: Mode shifting

The private internalized farmland could transform into a externalized tourism based or economy based farmland that generate the renovation of the whole area.

All public farmlands shift into new public park as landscapes or squares.

Schematic methodology

A methodology is designed according to the program and the chessboard model, corresponding to the existing site. Simple modification and adjustment will be made according to the grid pattern.

Decomposition

The project is decomposed into three diagrams: figure, ground and connection. Each of the parts is further decomposed into more detailed components with simple descriptions and analysis.

Furthermore, to reach a certain accessibility, a part of the private property would become a public pedestrian. Therefore, a continuous cantilever roof system is created to enhance the privacy of the public pedestrian.

Initial phase

Greenery and public square which provides open space for the café are positioned between commerce and residences. The gym and café provide direct services to the swimming pool, which could be a fish pond in the initial stages of development.

Initial phase

An axis is position between the 2 commerce, create a park/square that formerly could be a large farm or reindeer husbandry center. Another development proposal of hotel and reindeer experience center is also feasible.

Initial phase

Residence-only type is designated as a private area in which the farmland in the middle is only for the residents on the 4 sides.

02 Monument renovation: museum design

2018-2019 Fall History Design Studio

Site: Turin, Italy

Site area: 4006m2

Personal design based on academic studio

Rem Kolhass once said preservation is overtaking us, which emphasized the excessive unnecessary preservation undergoing in the global range. However, preservation, restoration and renovation are the three motors that drive the development of ancient cities. And Turin is exactly in the awkward position between modern renovation and historical preservation. Therefore a question is raised: how can we proceed new renovation on old structure without excessive meaningless preservation?

In order to find a solution, I picked one of the oldest monuments in Turin- Porta Palatina, as an example to study its history of preservation. Starting from a sensorial understanding of the monument's history in order to create a relationship of LOCUS that guides the following process. A series of rational research of value superposition and space formation matrix is made and developed into new language of space. According to the LOCUS relationship, a new museum is designed underground.

In the project, an "integrated" and "condensed" museum renovation was made underground against the monument, which forms two different central spaces that function separately as main circulative core and exit, between which are different types of spaces that stack together and form a complex holistic space.

In Hugo’s Notre Dame de Paris, he dedicated a whole chapter discussing "Ceci tuera cela": this will kill that, which means a book was to kill an edifice, as after the printingpress, one no longer depended on the sculptures at the Cathedral and the words of the priests to understand the meaning of God’s Words. As books killed the function along the forms of a church, modern individual are below the clouds of humanly constructed ideologies, and modern architecture worships function over forms.

The LOCUS

Aldo Rossi mentioned LOCUS as a subtle relationship between objects and between components within the object itself. A preliminary understanding of different components and the site of monument is shown as a ring diagram, which indicates a condensation from volume to point, while the components' influential radiance changed from inward to outward. A preliminary proposal is made according to the LOCUS.

Standardized structure unit: library design

2018 Spring Future Library Competition Site: New York, US Site area: 1729m2

Personal research and design

Libraries are the warehouses of information and knowledge that transcend years even centuries, and also provide the services of studying and cultural activities. Tradition libraries always follow a certain form that generate from larger volume to smaller spatial divisions. The big-tosmall design methodology creates such problem as the efficiency and usage comfort of the space are ignored due to the general control in the beginning of the design process.

A reversed thinking of small-to-big methodology could largely take human activities and dimension into account and consider the basic human comfort and efficiency in space usage. Starting from reconstructing the actual scene of studying and its space using, a standardized units are created and combined together in a loop of relationship to build subtle atmosphere in library study and book (information) storage.

In the project, two separated area named Yellow (open) and Purple (closed) are blocked from each other and start to intertwine along with the rise of level, in which a loop of circulation is formed and an interesting experience of encounter and separation emerges throughout the development of the spaces.

Three basic forms of library are chosen above. These traditional libraries follows a particular pattern as linear, circular or radiative, etc. that define the overall position of the bookshelves in entire library, therefore used spaces are the result of the bookshelves. This might lead to the lacking of consideration of human scale in the design process

Traditional library Schematic concept

The project is user-oriented instead of space-oriented, therefore users are divided into 4 categories shown in the matrix on the left: individual-open (IO), group-open (GO), individual-closed (IC), group-closed (GC). IC and GC users are encouraged to become GO users and get involved into a more sharing atmosphere, and break the distinct boundary among the 4 categories. Hereby, yellow is designated for open and dynamic atmosphere, purple is designated for closed and formal atmosphere

Isotope

Reversed spaces: residence design

2016-2017 Winter Site dwelling Competition

Site: Salir do Porto, Portugal Site area: 389.6m2

Personal research and design

When it comes to Southern Europe like Portugal, the atmosphere and relationship between oceans, beaches, mountains, cliffs, etc. are so subtle that living becomes more of an enjoyment and imagination. The project site is located on the cliffs of Salir do Porto, where the ruin of an ancient chapel sits on one side of the cliff. There is no more practical problem to be solved in this project, but to discuss in what way architecture could inspire imagination and enjoyment of living.

The starting point is still the ruin. Basic analysis of atmosphere is made concerning the site and the ruin, which further guided the decision of corresponding function. And to protect the ruin in its largest extent, the project mirrors the ruin completely to the other side of the cliff, given that the bay is symmetrical. A mimic and reverse of positive solid wall into negative circulation spaces creates a new sense of living develop from the ruin and inspires different interpretations and thinking of it on the other side. Therefore the project could be regarded as an isotope of the ruin.

In the project, the functional spaces of a residential housing are positioned around a central court yard which corresponds to the center chapel of the ancient ruin, indicating a sublime and variable feeling and relationship of different ambient. Walking inside "the wall" arouses the sensation of haziness between past and present, and therefore a picture of what lives were like in the past gradually emerges in mind.

The new project is designated to reminisce history and inspire thinking and imagination, therefore a reversed and mirrored residence is located at the cliff on the other side of the bay. A subtle relationship of isotope is emerging between the residence and the ruin.

Walls to spaces

parts of the ruin solid walls are chosen to transform into space and create different spatial experience in circulation area. Together with the visual/physical connection, the relationship between different spaces are getting clear.

Spaces formation

The project is a reverse isotope that could nest the ruin inside its circulation. A series of additional functional spaces are attached to the "reversed wall". The "walls to spaces" result on the left page are clearer in the sectional axonometric view.

Student's activities: high school teaching building design

2021 Spring Undergraduation Design

Site: Yunfu, Guangdong, China

Site area: around 28600m2

Personal research and design

Chinese students are required to choose only from Art or Science subjects for their College Entrance Exam until recently a new policy is carried out, giving students more possiblities to choose their preferred subjects for the Exam. Therefore, the subject-selection system is introduced to the campus and gradually replaces the original administrative system that class is normally led by a class teacher. This shift of teaching pattern requires new spatial and functional models for future educational resillience: how to create new typologies of teaching building to adapt to new policy framework becomes the essential problems in the project.

A case study of advantages and disadvantages of existing educational facilities is made in both terms of administrative system and subjectselection system, which would help to extract suitable elements and spatial patterns for the design. More importantly, a research of students' needs in different years and their behaviors based on these needs are made and analyzed. We found that senior 1 to senior 3 is a gradual transit from full-administrative system to full-subject-selection system, in which different students have various school lifes and activities.

The project is seperated into 5 different entangling area in order to satisfy requirements from the students in different years: senior 1, senior 2, senior 3, activities and subject-selection area, where each of them has their own special spatial configuration and atmosphere. These areas eventually are connected by a centralized courtyard platform, providing more public spaces for students to gather and enjoy their campus lifes.

1 Subject-selection system

The newly introduced system provides in total 12 different combinations for the students. Solid frames are previous science subjects and dash frames are previous art subjects.

Hereby, a presumed class calendar of a student who chooses physics, geology and chemistry as his subjects is made, and the following diagrams show the trajectory of the student within one day.

long + 10 short 20 long

Admin system is a polycentric mode where student's activities happen around the admin classroom. Long commutes always happen between different facilities.

Subject-selection system is a multicentric mode where students commute between different spaces and facilities. In this case, all the commutes are long commutes.

2 Commute analysis: chaos

If an equation was made from the two cases above, we can come to the result of 1 short commute = 0.6 long commute, which is a small difference. Imagine thousands of students having long commutes during breaktime, the public spaces would become extremely chaotic and crowded instantly. Therefore the reduction of long commutes becomes a necessity to prevent this chaotic situation.

Teacher offices locate between 2 rows of classrom facing south, which could stimulate the interactions between students and teachers.

Senior 3 area works in full-subject-selection system, which closely connects to the subject-selection area. Different from senior 1 & 2, its spatial and functional organization is independent, far away from the activity area. A narrow balcony (public study area) is formed due to the displacement of the classrooms, providing spaces for students to share ideas and experiences on the subjects.

Water collection system: eco-hostel design

2021 Columbia GSAPP Fall Advacned V Studio

Instructors: Vanessa Keith, Andrew Homick Site: East End, Jamaica Site area: 3000m2

Group research with Leah Smith and individual design

According to the book Our Final Warning: Six Degrees of Climate Emergency, written by Mark Lynas, he says that the global warming have already beome a non-negligible problem in the new century. Jamaica is an island country where environmental issues are influential and deciding. With further research, we found that flooding and drought might become a critical issue on the island in the future due to climate crisis. Therefore, the question of how to combine architectural design with resilient adaptive technology to tackle with environmental problem needs to be put on the table.

A simple design of rainwater collection is introduced to the project, in order to give resilience to the riverine flood condition, and help to redistribute the water resources during drought period. The design could be incorporated with the architectural structure and water supply/ drainage system. Collaborating with FMJ property, the project is consider to be beach hostel that provides amenities and services for the ecotourism in Jamaica, which could generate economic benefits for the region and client.

The core of the design is a series of water collector funnels that collect, purify, recycle and reuse the water from outdoor environment and within, to maximize the efficiency of water use and also to create a unique interactive atmosphere with water.

Flooding future

Due to the intense river system in the east part of Jamaica, coastal flooding as well as riverine flash flood will occur in the site area. Also these flooding areas are highly overlapping with agriculture zones. Therefore, our project intends to mitigate this situation and incorporate devices into infrastructure and architecture.

Funnel device

Flash floods always occur during rainy season and around intense river systems. Therefore, a funnel-like rainwater collection prototype is designed for mitigating the situation. This device could be incorporated into architectural structure and design, as well as itself being a leisure destination. The funnel functions to collect rainwater and allow it to travel through the hydroelectric power generator. The water can then be stored and pumped up again for irrigation during drought conditions

Programming

According to the analysis of the topography and hydrological features of the east end, the site is separated into three parts: the upper river, the lower river and the east end. The upper river is our frontier site for the diversion valve system, to divert the riverine flood at its beginning. In the lower river region, we are considering setting up a series of markets as well as parking spaces for road trip travelers. This would form a linear protection barrier, which is in blue, for the crocodile sanctuary, which is in green. And lastly, the East End, where our eco-hostel and oceanographic research center are located.

Water flow diagram

The project’s core is the circulation and flow of water. Rainwater comes from above and enters the funnel collector leading to down pipes that are for the services such as guest rooms and restaurants. Some water will go through a water curtain system that would give the visitors a different feeling of walking through and between water. And that water will enter the storage tank installed below the deck of the first floor. After the treatment process, the water could circulate back to the roof through the light green funnels and be used for water curtains again or for services usage. The used water will leave the system through the drainage pipes.

The Red Ritual

Light experiments and trailhead pavilion design

2022 Columbia GSAPP Adavanced VI Studio

Instructors: Stephen Cassell, Annie Barrett Site: Sedona, Arizona Site area: 225 m2

Personal research and design

The boundary between man-made world and the nature has always been a interesting point of view to discuss. Sedona, to which hiking trails and street systems dominated, is one of the most appropriate examples to research and design the relationship of these very opposite concepts. How to deal with the abrupt rupture from the man-made streets to the hiking trail to wilderness? What kind of junction should it be to deconstruct and reconstruct, or to say, to transform the human mental sprits from one world to another?

The research started with experimenting how light would be transformed after passing through a series of mediums. The changing of container materials, the mediums, and the environment, would lead to different result of the lighting and shadow and most importantly, the atmosphere and sensation of the space, which becomes the main methodology of the following design. Grasshopper became the major tools to determine the spatial configuration and the volume of the design.

The design is a pavilion that connects the parking lots in the trailhead and the trails to the rocks, where a series of spatial rituals happen and change the visitor's feeling and emotion during the whole walking within the rituals. There's special atmosphere of each space created by its own attribute of size, loudness, brightness (from the design and use of material), which correspond to one mood for the visitor to feel.

Governance

governance: borderland biostructure design

2021 Columbia GSAPP Summer Engtangled Studio

Instructors: Ersela Kripa, Stephen Mueller

Site: US-Mexico border, vairous locations Example site: El Paso, Texas Personal research and design

Biosecurity has always been a critical and contraditory issue along the border area. In fact, it's quite easy to manage human immigrants and animal imports, but not so easy on governance airborne pathogen, such as Coccidioides, our protagonist in this project. This fungus locates in the surface of soil and would be transmitted through winds and leads to a disease called valley fever. Environmental issues such as dust storm is so prevalent along US-Mexico border that make the borderland an endemic area. The question of how to counteract the governance of fungus and how to establish a new system that could manage air condition, environmental quality and human health is casted on the topic.

A new binational governance is designed considering different potential actors that would engage in the project, including goverment, scholars, initiators and workforce. Also geo-engineering techniques are introduced to the project to modify the soil and ground condition in order to improve the environmental quality for the border area. New binational relation are established after the execution of the planning above.

Furtherly into architectural scale, the air chimney and nonwoven fabric is introduced for indoor living quality improvement. The air chimney locates at the center of the house or public facility, which is for the installation of air purifier or air pipes; while the nonwoven fabric is used for enclosing the architecture and create a semi-open space to attract people to the outside environment.

Re-thinking BIM

Long Line Building facade renovation workflow design

Instructors: Mark Green

Fall Elective Course/ September 2021 Group research and design with Ralph Cheng

Our capabilities as architects today, to create and leverage organized building information, is continuously expanding the possibilities for designing and understanding what we build and how we can build it. Developing a literacy of the digital tools and how to leverage them through informed design practices that exist both within the architectural field and more broadly, is an increasingly essential competency for designers. This class challenges students to develop robust methodologies and frameworks to better drive possibilities for creative iteration and validation of design solutions through analysis, automation, simulation, optimization, and representation.

This course is intended to provide foundational knowledge of building information modeling (BIM) practices, as well as relevant options for alternative design-platform interoperability and integration.

For the final project, students will select one or more approach to interoperability and design intervention, leverage the affiliated platform(s) to develop their advanced parametric and design-informed methodologies, and apply them to the models developed earlier in the semester with a revised set of design goals.

If Building Could Talk

Back to Back: interactive installation design

Instructor: Sharon Ayalon Spring Elective Course/ Feburary 2022 Group design with Bisheng Hong, Chuqi Huang, Hao Zheng and Hazel Villena

Aiming to link Harlem’s daily life and diverse culture heritage to Columbia University, the project is located at the most dynamic stairway on the central axis. Boxes are designed as containers to suppoort daily activities for Columbia communities while recording the everyday life of Harlem.

Four maps related to the food, art, music, and historical building are set on the eight boxes as puzzles. By moving around the boxes, people can actively explore the miniature Harlem. At the same time, the volumes can turn into small tables or shelves for people during their break.

During the daytime, materials with different textures and colors are used to guide the puzzles, enabling people to participate in the interaction. Pockets are designed to place in iPhones as lighting sources. The translucency of the materials makes them possible to explore during nighttime as well.

Free Studio Seating

Optimization project on studio seating re-organization

Instructor: Danil Nagy Spring Elective Course/ Feburary 2022 Group research and design with Siye Huang, Siyu Xiao, Yuening Jiang and Yutong Deng

In the past decade, our interaction with the world has been deeply affected by artificial intelligence. Many industries including finance, science, and manufacturing have been revolutionized by developments in Machine Learning, optimization, and other artificial intelligence technologies, which have allowed them to leverage the power of computing to solve complex problems in new and innovative ways.

Meanwhile, architectural design practice has been barely impacted by these developments. Although almost all designers use computers in their practice, the tools they rely on have not leveraged these emerging technologies. As a result, the design profession has not substantially evolved since computers were first introduced to the design world nearly four decades ago.

This course will introduce students to the basic concepts of generative design and teach them how to create complex models that can be controlled and evaluated by an automated search algorithm. The Python programming language will be introduced as a way to amplify the generative complexity of parametric models in Grasshopper. We will also cover techniques for evaluating designs including using third-party Grasshopper plugins for structural and environmental analysis.

1 Introduction

The current condition of classroom seating arrangement is in a linear organization, meaning an central axis of major circulation, with branches to each of the studios. This organization ignores the privacy between students and the collective relationship within each studio. Also, it minimizes the possibility of interaction, communication and creativity. It is difficult for students to discuss while giving individual spaces with only one long desk.

Therefore, our project intends to reorganize the seating for the studios, in order to enhance the possibility of communication and interaction. We provide three different types of desk: single, double and triple, for different group structures (individual work, 2 people or 3

people group work) as basis for our rearrangement.

However, it is still difficult to quantify the term “privacy” and collectiveness”, and the traditional way of putting desk manually might be subjective and less effective. Therefore we introduced Grasshopper and Discover to optimize the seating organization with certain parameters: distance and overlapping area. The larger the overlapping area is, the more collectiveness the area could get, or vice versa, the smaller the overlapping area is, the more privacy the area could have. With these two different opposite trends that control the whole optimization process, we believe that there will be a balance in between for the best arrangement for the students future use.

2 Methodology

We set a series of points in the studio classroom plan for generating the studio group area, the desks and their movement range. We start our optimization process by minimizing the overlapping area between desk movement ranges (for privacy) and by maximizing the overlapping area between desk movement range and the studio group area (for collectiveness) to reach a balanced state. Our process are introduced below:

Step 1 Optimizing the area and position of 8 groups in the studio, using the distance to the classroom boundary as parameter to control the major circulation space from the entrance to each of the studios.

Input:

a. Coordinates of 8 rectangles’ centroid b. Rectangles’ size c. Boundary of classroom

Optimization process:

a. Minimize distance from classroom boundary to the rectangles’ centroid

b. Minimize overlapping areas between rectangles

Step 2 Each group contains around 12 people(11-13), a set of circles(representing movement range of different types

Overall result Manual adjustment

Overlaying results

of desk for discussion and individual work) are distributed in each group boundary(the rectangle).

For each group, the circles are optimized to repel each other (privacy between students) while attracting by the rectangle (collectiveness within the studio). And between groups, the circles are also set to repel each other. Both privacy and collectiveness are controlled by the overlapping area between circles and rectangles. The process is conducted group by group instead of 8 groups together.

Input:

a. The number of different types of desk b. Coordinates of circles’ centroid c. Circles’ radius depends on types of desk d. Rectangles from last step

Optimization process: a. Optimize the number of each desk type b. Minimize the overlapping areas between circles c. Maximize the overlapping areas between the circles and rectangles

Step 3 Manually operating and adjusting the orientation of the desks to better fit in the classroom for circulation

3 Results

We try to optimize the position of the desks all together, however, the result doesn’t show any trend. Therefore we decided to change our plan to optimize group by group, so that the trends could be salient. As a result, from the Discover chart we could see that the trend is salient in all the optimization (step1 & 2)

In step 3, we also try to rotate the desks in certain angles as input parameters, and set the constraint that the overlapping area should be less than 0. However, Discover doesn’t give us any optimal result, so we choose to manually adjust the angles of each of the desks.
