CONTENTS

The Urban Oasis

China has accomplished economy growth at a fast pace; however, it couldn’t improve the quality of life as much as economic prosperity. Wealth has been concentrated on a few people. As a result, this caused a serious social issue, education inequality. The Hukou system, which limits public education service within region of birthplace, aggravates the issue more. In the future, this will be more serious when increasing elderly education demand is combined with the Hukou system and the gap between rich and poor.

In this situation, libraries where anybody freely acquires knowledge can be a good solution to deal with the issue. However, the spread of education is not prepared in libraries because its architecture type has mainly been the repository of books. Then, in the future, what should libraries prepare for as a solution to handle the expected education issue?

THU Thesis Project Building Type Mixed Use

PLACE 8hao, Shuangqing Street, Haidian, Beijing, China

YEAR 06, 2019

How should future libraries be in urban areas?

The site is located in a residential area consisted of apartment complexes, which can be easily seen in Chinese megacities such as Beijing. Because this area has been recently organized, the population is increasing; however, there is a lack of commercial and public facilities compared to the increasing population. A village for immigrant labors is located in the west-north area. To have a library effectively solve expected education issues, a new library type is needed to be suggested that not only increases educational functions but also improves the life of residents.

To make the library of this project come closer to residents, library programs and various programs for daily life are combined in one building. In addition, to solve the disconnection caused by the area’s urban elements, the dynamic building form is designed.

ShoppingZone

TransitionZone

Shopping Zone Library LearningCenter

The Place for Everyone

The building provides free space where anybody can freely stay. Commercial spaces along free spaces not only enhance the vibrancy of the area but also connects different programs, education, and commerce. Transition zone consisted of bookcases filled up with donated books, resting places, and small shops works as the indoor free space. Various education programs which seen between bookshelves attracts people who finished shopping, to the learning center and the library.

The Mass and its the atrium were designed considering sun altitudes for sustainability. To maximize inflow of natural light, heliostat plates are installed on the ceiling

The library with everyday life

Spaces in the library are endlessly connected with each other to promote interaction between people. Commercial programs, the plaza, and park which surround library programs provide convenience and chance to increase the sense of community. By combining a library with everyday life programs, this library becomes the urban oasis where anybody can enjoy various activities from education and culture to shopping and rest.

The Model Wall

I.M.Pei said ‘life is architecture and architecture is the mirror of life.’ This means careful consideration of society and its changes are very important to design a good architecture. However, contemporary architecture schools fail to provide the education expanding students’ insight on society and architecture. THU school of architecture is one representative example of this. The school building filled up with only conventional rooms for research and lectures disconnects students from other activities happening outside. They can learn building design, however, cannot learn architecture. In this situation, the project’s question starts; To connect students’ architectural knowledge and society, What spaces and educational environment should architecture schools have?

Architecture : Mirror of Society

Spaces and forms of architecture are mirrors reflecting zeitgeist. Thus, architects need to give careful attention to the time’s changes occurred by human activities. To achieve this aim, the project connects this building with surrounding schools and provide spaces where students from different majors easily can meet, talk and work together. By this, the architecture school becomes the knowledge center of Tsinghua University as the first step for students to understand society.

The Model Wall: The Model Wall is a strong architectural element which connects activities happening throughout the architecture school building as well as disconnected two masses. By making activities recognized anywhere in the building, endless connected floors between the Model Wall increase people’s interests in these activities. Moving inside the building, people can feel changes in architecture by seeing students works filling up the model wall. In this project, the model wall is utilized as an educational method beyond a role of an architectural element.

Algorithm-driven Design in Architecture

Currently, AI is widely used from agricultural fields to industrial fields, and its technologies are fast being developed. However, its usage is very seldom in architectural design. Because it is very difficult to establish criteria of abstract elements for A.I scripting, such as general definition of beauty, space efficiency, human activities in buildings and etc.

However, if its utilization is slightly turned from having A.I work whole design process to A.I assistants helping specific steps of the process, the possibility of utilizing A.I can be infinitude. By providing A.I the information such as preferences of an architect on forms, spaces, numerous and diverse design solutions which an architect is able to refer, can be rapidly generated. The utilization of A.I in architectural design can be the strong catalyst helping architects clearly organize their abstract thoughts and efficiently construct these into physical forms and space.

Algorithm Procedure

The project aim is to make AI providing diverse building forms and materials for the architectural design process. As an example of this aim, AI is designed, which can suggest new forms and material expressions based on digitalized information from existing buildings.

To digitalize spaces and materials of existing buildings, two buildings, Galaxy Soho and THU Art Museum, were taken photos by a 360-degree camera. The AI of this project pixelates images and grows each pixel following already input directions of AI script. The group of grown pixels (Voxels) becomes a building form. During this process, architects can input data depending on their preferences and check the result in real time.

Precast Concrete: The shade structure of this project is inspired by the framework of Geodesic Dorm. By connecting equilateral triangles with a specifi c angle, various structure forms suitable for shade structures can be designed. As these structures are made of the same regular triangles, their components can be modulized.

Reducing Weight Surface Experiments #2 Assembly

Procedure: The module has two components. For easier connection between components, 3D-printed joints are devised. Diverse experiments from structure of modules to concrete mixture ratio were conducted to reduce weight of concrete modules. Casting forms are designed with various materials expressing China’s regional characteristics.

After Library

Dalseong county plans to build a new library in Guji-myeon to accommodate its increasing population. Urban planning and expansion have brought big cultural and topological changes to the area, so the library must consider its own changes to be practical. It should also take into account the rising popularity of digital books which are used on smartphones, tablets and so on in ways quite different from traditional books. The methods of library storage and access for digital books present challenges to and opportunities for the Guji-myeon library. How can it anticipate these changes and adapt to better serve the public’s needs?

Change 2. New needs

Economic expansion policies have increased the population of Dalseong County exponentially. Efforts have been made to use the area’s natural resources, such as the Nakdong River and abundant mountains, as locations for leisure facilities. Areas that were once expanses of rice paddies are now being made into parks and other community centers. This project could be very easily and very reasonably placed among them.

Change 3. New type of mankind

The digital revolution of the 21st century, with the overwhelming emergence of smartphones and tablets, etc., has changed society dramatically, particularly among younger generations. Young children and teens are more familiar with literature and other print media on small, glowing screens than on paper. Printed books may not be the primary method of disseminating information in coming generations. Libraries must anticipate the popularity of digital books and redefine what a library books like and does.

Change 1. Attack of building blocks

Under the direction of the Korean government, new industrial complexes are being built in Dalseong County to improve the economic well-being of the region. But this policy does not consider the cultural and natural resources of Dalseong County. It can destroy irreplaceable historic sites and beautiful landscapes, leaving only large-scale, often unsightly factory and housing complexes instead.

Mass Process

Step 1. Form

To emphasize the library’s setting amid beautiful natural scenery, it has been given an oblong shape to provide an abundance of windows and vistas.

Step

2. Connection

Koreans love biking, and the area has many bike roads available. The library will capitalize on this passion by incorporating a long bridge that can connect biking inflows from the area. The library will serve as a convenient, pleasant stop along several local bike roads.

Step 3. Void

The rise of digital books brings a change in where reading can be enjoyed. This library will expand the concept of reading space to include not just the inside but the whole of the surrounding library space. The library will become a large server, permitting visitors to roam the library grounds, enjoying the landscape and reading wherever they please.

Constantly changing bookshelves

Current bookshelves Books disappearing from the bookshelf The Spectrum Wall of things from daily life

TheSpectrum Wall

When books disappear, do the bookshelves have to disappear as well? Perhaps not. This project will adapt available bookshelf space into the Spectrum Wall. The Spectrum Wall will preserve and display local items and images displaced or destroyed by urban planning and development. Items and images could include children’s diaries, family photos, tools from past trades and so on. The items in the Spectrum Wall will reflect the flow of time across the bookshelves. The library’s glass surface allows visitors to see the flow of time and be reminded of memories and events that cannot be felt the same way with books alone.

Landscape drawn with light and shadow

The timeless natural landscape of Dalseong county is being devastated by new urban planning and development, which rarely consider the preservation of natural resources. In this situation, this project highlights the natural beauty around the library by using a roof and a wall as a canvas. Light and shadow become a brush and paint to draw surrounding nature on the wall. Time, seasons, and weather will endlessly draw new pictures of nature.

Urban Slope

The site is located in Gangnam, which is called the most dynamic district in Korea. The district has powerful agent leading various fields from culture to business. However, in the backside of the shining light of Gangnam, lots of shadows exist. The district does not have enough public open space such as parks compared to the population because the real estate of Gangnam is the most expensive in Korea. This makes people move like robots and causes disconnection between them. In addition, the high density of buildings and high electricity consumption causes serious heat island during summer. In this situation how can a new building deal with the issues?

Gangnam, the light of Seoul

The site is located in Seochodong, Seoul, which is reffered to as Gangnam. The district consists of lots of skyscrapers and facilities for diverse business. As the heart of the business district of Korea, the place releases powerful and dynamic energy. The office building, which will be constructed in the site, needs to consider how to accept this energy, and express it as an architectural language which can make the enviroment better.

The shadow of Gangnam

Gangnam is a CBD which has the most dynamic energy, but has a poor environment for living. The district has insufficient public open spaces compared to its population. It is very diifcult to produce the open spaces for the public when the average real estate cost of Gangnam is the most expensive in Korea. How can a new building deal with this issues of the district?

Building energy consumption of Seoul Heat island of Seoul

Evironmental issue of Gangnam

Gangnam is the district which has the highest energy consumption in Seoul. In addition, the high density of skyscrapers release significant heat onto the roads of the district. These environmental issues cause a great heat island effect during summer and higher electiricity loads.

URBAN SLOPE

This projects tries to design a skyscraper which is able to cope with the urban and environmental issues of Gangnam. Urban Slope, the concept of this project, shows how green arhictecture can make the site better and produce public green open space for the citizens. This can develop the dynamic energy of Gangnam.

Gangnam Hongdae Yongsan Songpa Dongjak Kwanak

Analysis of program needs

This graph shows the citizens of Gangnam want public and open spaces. They want to use their free time around their work schedule for social activites. Usual office buildings have a dichotomy between work and other activities, and have not been able to produce the space for the people’s need. To solve these issues, this projects scatters the diverse spaces for their needs throughtout the building.

Step 01. Reducting solar radiation on model surface

To reduce cooling energy consumption during the summer, this project tests which shapes absorb less solar radiation. The experiment shows a rotating-cylindrical model absorbs less solar radiation than a cylindrical model or an oval model.

Making Urban Slope

The design of Urban Slope first considered using natural winds to ventilate the building. This project wanted diverse programs for the needs in the building to not only increase social connection between people but also operate as eco-friendly spaces. The horizontal air tube for natural ventilation of the building is tilted to attract peoople from the outside, and diverse programs are arranged along the inclined axis.

Step 02. Seperating core

To maximize natural ventilation in the building, the building is designed with 3 separated cores. With one core plan, the building prevents air flow from passing through it; however separated cores can increase natural ventilation.

Step 03. Putting Urban Slope and an atrium

Urban slope, open spaces rotating and rising along with the building, promotes various activities. In addition to Urban Slope, an atrium provides sunlight throughout the building reducing lighting electricity load incresing efficiency.

3 core plan

Mass study

The form of Urban Slope considered how to express the dynamic energy of Gangnam as an architectural language. The rotating cylindrical mass attracts people’s attention from the surrounding areas and makes them curious about the building. The curiosities motivate them to explore the diverse activities in Urban Slope and amplifies the dynamic energy of Gangnam. As a result, Urban Slope will promote the sustainability with its public open spaces.

Passive Architecture

Many skyscrapers fail to achieve green architecture even if new eco-friendly technologies are used because most of them have low practicality compared to their high price. The buildings use curtainwall systems which have low heat insulation property. Although the buildings have certification of LEED, the actual energy performance score is lower than the buildings which were built 100 years ago such as Empire State Building and Chrysler Building. Considering this issue, Urban Slope uses a lower rate of glass walls and increases thermal insulation in the wall.

Sustainability of Urban Slope

The open spaces of Urban Slope connect people using different programs. The connection will gather people more and more to the open spaces. By the connectiion, Urban Slope will have the energy which makes each open space create its own character. The spaces will grow by people and their activities, not by money and economic policies.

VERTICAL ALLEY

104 Village has been loved by Seoul citizens because it has kept Korean style living and atmosphere. However, the village has suffered from decline in the last 30 years. Now, most houses of the village are empty, which has caused Seoul City Hall to start to plan its redevelopment by replacing old buildings with apartments over 20 stories. With this policy, the preserved atmoshphere will disappear. With the cost of real estate soaring, this project tries to find the architectural solution that is able to deal with the problems, and let the village get its liveliness back.

The decline of 104 Village

The site is located in 104 Village, Seoul. Because Seoul City Hall implemented massive redevelopments in Cheonggyechoen, Changshindong and Yongdeungpo during the 1960s, many residents of the regions had to migrate. The poor people started building a shanty town in the site which was a mountain at that time. Although the town might look dirty and undeveloped, it has accumulated the style of traditional Korean living, which shines as a pearl in the city of massive block apartments, and has become a place which Seoul citizens love.

However, the town has declined after new apartment blocks were built next to the 104 village. This caused shops scattered throughout the village to move closer to the apartment blocks. When the shops, which produced liveliness in streets of the village, started to disappear, the village also started to lose its vitality. Many houses have been deserted throughout the village. As a result, Seoul City Hall has planned a new massive redevelopment at the site.

Seoul, the city of the poor

From 1996 to 2001, Korea went through a deep recession. After the Korean Economic Depression, real estate has become the best investment. As a result, average real estate costs in Seoul have skyrocketed to 5 times the cost of 2003 while the average wage growth has only tripled. Rent has also soared and many people suffer from being House Poor. Having a house has become the dream of Seoul citizens.

VERTICAL ALLEY

104 village is destined to be redeveloped into the massive block apartments style. The redevelopment will cause real estate costs to rise and to destroy the atmosphere that the village has kept. To prevent this, this project propses the prototype which can preseve the atmosphere of the 104 village throughout the redevelopment. Maintaining the atmosphere of the alleys, with small locally own shops and restaurants throughout the village, can give it liveliness and a more traditional feeling.

Making a vertical alley

There are many attempts to envision the vertical village. However, the attempts have simply concentrated on how to stack residences vertically. This has caused the disconnection between people and has also caused villages that have no character. This project has attempted to move the usual atmosphere of an alley, which is the basement of daily life, to the vertical village. By putting irregular residences, the vertical village will have gaps within itself. The gaps will be filled with the diverseness of an alley, and have the chance to make its own character.

Vertical alley over corrider

Traditonally hallways in apartments are simply a path for vertical movement. However, when shops, resting places, and gardens are placed along the hallways, people can walk, talk, and creates memories with neighbors throughout it.

Connecting vertical alleys

To make the vertical villages connected to each other, facilities of everyday life are put throughout the villages, like streets of small town, with shops and restaurants conveniently located near residences. Public facilities such as playgrounds, libraries, and public toilets, are put on the ground floors. These become the entrance which attracts people to gather and connects the vertical villages. On the upper floors, commercial shops, typically found at street level, are put along vertical alleys. This makes people travel throughout the vertical villages.

Various types of blocks

Eco-friendly construction

Recycling of module

The vertical villages consist of modules. A module can be assembled with diverse panels consisting of different materials. Because 104 village will be torned down, lots of building remains will become waste. The waste can be reused as exterior or interior materials of a module. By this way, the vertical villages also can preserve the architectural history of 104 village and give character. In addition, the structure of a module is basically a steel structure which can be recycled into many different products after the buildings lifetime.

In Korean Building act, a parking lot has to account for the most area of ground floors of apartments. Because of this regulation, usually parking lots remain as a dead space. In this project, the parking lot is designed to have open public space when parking lots become empty during day time. By this, the dead area can have a new vitality as the main key to make people communicate each other

GREEN CHEOMA

Modern architecture has caused serious environmental issues.

The phenomenon is based on the architectural arrogance with architecture trying to control the environment with technology. However, the technology has totally failed to conquer nature. In this circumstance, traditional Korean architecture shines its eco-friendly traits. The traits were based on understanding nature, working with nature instead of against it. The wisdom of the past must be an important key to handling the issues of the present in an eco-friendly way.

Cheoma, traditional Korean eaves, shade the rooms of the Hanok, a traditional Korean house. Because it is designed considering the angle of the sun of all seasons, the Hanok gets less solar radiation during summer and more during winter. The idea of Green Cheoma starts from the eco-friendly wisdom of Cheoma.

Site Analysis

The site is located in a district of Sejong City which is currently in development as a new city. The city wants to develop the district as a growing town that accomodates an increasing population in the future. The site will be the center of the apartment complex.

The city is planning a community center on the site. However, it will be surrounded with the forest of apartments. The concrete forest will cause a thermal island effect in the district. The site needs architecture which can deal with the expected side effects.

Cheoma , traditional Korean eaves, shade the rooms of the Hanok which is a traditional Korean house. Because it is designed considering the angle of the sun of all seasons, the Hanok receives less radiation during summer. This means the inside of the Hanok is dry and cool compared to the outside zone heated by the sun. In contrast to summer, Cheoma makes rooms of the Hanok obtain more sunlight during winter, which warms the rooms and provides natural sunlight. Cheoma is a efficient heat controlling system without using energy. The wisdom of it can be adapted for an architectural solution to reduce thermal loads of a building.

Maru is a living room of the Hanok. During summer, the south zone of the Hanok is heated. On the contrary to this, the north zone of the Hanok keeps relatively cool compared to the south zone as the roof of the Hanok provides shade in the north zone. The temperature difference between the zones lets the air of the north zone move to the south zone. Air in the heated zone goes up, which causes a low air density area. This makes the air of the north zone, which has higher air density, to move to the south. As a result, the air current steals heat from the Hanok. With this system and the shade provided by Cheoma, Maru becomes a great place for people to gather together.

Site plan

In Korea, hot and humid weather, ranging from 32°C to 38°C during the summer, causes significant energy consumption. Although cold weather causes heating energy consumption during winter, energy consumption in summer is 1.6 times higher than winter. Thus, it is more important to consider methods to reduce the energy consumption and solar radiation on the surface of a building during summer.

Wind path - CFD simulation

Summer wind path of the site is generated by South-Eastern wind, which is a seaonal wind of Korean summer. The wind passes thorugh the middle part of the site. Preserving this path can help to reduce heat emissions from the building. Winterwind path is a seasonal wind path flowing North-West, the apartment layout will change the wind flow throughout the Cultural Center site. This changed route will make contaminated air of the town naturally ventilated away from the site, thus the wind path needs to be preserved.

Waste heat recycling system

Green Cheoma uses waste heat emitted from the building to generate electricity. The pressure gap between the inside and the outside of the building makes the air current faster. The accelerated current turns micro windmills which are set up on the truss structure, and the equipment produces electricity.

The science of Haeinsa Temple

The Temple of Haeinsa is home to Janggyeong Panjeon, the most complete collection of Buddhist texts, engraved on 80,000 woodblocks between 1237 and 1248. Beobojeon and Soodrajang, the buildings of Janggyeong Panjeon, which date from the 15th century, were constructed to house the woodblocks. Because the woodblocks are vulnerable to the humid weather of Korean summer, the buildings are designed to have South-Eastern wind, a seasonal wind during summer. The wind passes through two different sized windows on the opposite side walls of the building to reduce humidity. The bottom window of the south wall is wider than the top window to get more air flow from near the ground which is less humid. The wind coming through the bottom window is hotter than the air inside, and it becomes ascending air inside the space. The air current goes out passing through the upper window of north wall which is designed wider than the window below to increase emission of the hot air flow. This creates an air current that absorbs moisture inside the building and keeps the building cool. With this eco-friendly design, Haeinsa has been able to safely preserve Janggyeong Panjeon nearly 800 years without any electrical equipment. Based on the mechanism of the structures, this project tries to utilized the design as a green arhictecture solution to reduce the humidity and temperature of the building.

Kinetic energy harvesting

Rainfall has significant potential energy which can be converted into electrical energy. By using a micro vibration energy harvester, the building can accumulate electrical energy from rainfalls passing through cylindrical atrium structures. This green energy system does not produce any pollutants. After the conversion, the water can be reused for facilities of the building.

The hot air rises. Cool ceiling systems use this to the benefit. This system allows rainwater to cool down the ceiling surface through the ceiling pipe. When hot air touches the surface, the air becomes cold and the temperature of the room lowers.

Cylindrical Atrium

Winter

In winter, the atrium inside the building is warmed by the sun. As a result, the air cooled by the low temperature of winter naturally warms. The warm air current rises along the cylindrical structure and spreads throughout the building.
