3 01 Floating Architecture 3

4 BACKGROUND Climate change sea level rising Social Change increase of population growth of claims Contradiction reduction of the land for residential settlements Contradiction higher demand for residential settlements 4

5 BACKGROUND Climate change and sea level rise Low-lying coastal areas are at risk of being completely submerged, disappearing under water. Construction ground is becoming increasingly limited. The maps show areas to be flooded with sea levels rising by 30 centimeters, 50 centimeters and one meter respectively, Mekong Delta, Vietnam- Photo: Courtesy of the 5Vietnam Academy for Water Resources 5

6 BACKGROUND Sustainable solution: not against the water but adapting to the water Source: R.Misdorp and H. van Reeken Floating buildings and structures 6

7 BACKGROUND Social change The shortage of the settlements due to a rapid growth of population The shortage of land resources for agricultural production and raw materials. The increased demand for high-quality residential accommodation. Source: Institute of Applied Plant Nutrition (IAPN) 7

8 02 Situation in Germany 8

9 FLOATING BUILDINGS Residential floating houses Holiday floating houses Diving school Floating offices Floating church 9

10 POST MINING LANDSCAPE Utilization of the landscape after opencast mining 10

11 RESEARCH AND DEVELOPMENT Investigation of the movement of floating objects Usage of power from the kinetic energy Heat storage Pontoons/floating body 11

12 03 Situation in Vietnam 12

13 GEOGRAPHY AND OUTDOOR CLIMATE The coastline is more than 3,260km long, as well as a criss-crossed river system. The coastal zones are divided into 3 regions; south, central and north. Located in a tropical monsoon climate region with significant impacts due to climate change and sea level rise. 1. Nam Dinh, Red River Delta, 2. Thua Thien Hue, central part and 3.

14 FLOATING HOUSES FLOATING VILLAGE Current status of floating houses in Vietnam Long term historical tradition Using simple structures and materials Lack of planning, water and energy supply systems, sanitation system Environmental pollution Some floating villages were demolished 14

15 CURRENT STATUS 15

16 AIM FOR THE FUTURE Based on values of traditional architecture, preserve and develop a sustainable floating community with floating houses adapting to climate change and sea level rise in Vietnam Preservation Lesson on microclimate, lesson on local and friendly environmental materials, lesson about garden and plants, lesson on how to use natural resources, lesson on how to built a floating community etc. Development Planning of floating community Innovative floating structure and lightweight materials Sanitation system Renewable energies etc. 16

17 04 Architecture and technology of floating buildings 17

18 SITE PLANNING Planning In accordance with local planning. Developing a sustainable concept of floating communities - floating villages. Developing different types of compound floating housing: Line of detached floating houses Group of attached floating houses Spiral staircase of the Information, Communication and Media Centre (IKMZ) 18

19 BUILDING DESIGN Structure and Joining System The technology of floating structures would correspond to the owner s economic condition. Using light-weighted, flexible and assembly structure. Spiral staircase of the Information, Communication and Media Centre (IKMZ) 19

20 FLOATING FOUNDATION (PONTOON) Reinforced-Concrete pontoon systems (Fa.Clement) Steel pontoon systems Wood pontoon systems Plastic pontoon system 20

21 SELF-SUFFICIENT FLOATING HOUSES Using natural resources such as rainwater, sunlight Using renewable energies such as solar panels, wind turbines 21 21

22 ENERGY USAGE Under-water-heat exchanger Passive Cooling-System with capillary tube mats 22

23 SANITATION Development of sewage systems and septic tanks Development of floating toilet concepts. Development of floating community waste management cycles. Improvement membrane filter system Source: BUSSE IS GmbH 23

24 05 Cooperation 24

25 CAMPAIGN Exchange, evaluation and improvement of existing scientific results Improving innovative processes crossing the boundaries of scientific disciplines and societies Cooperation will pave the way to shape our cities of the future, turning them into sustainable and secure living areas 25

26 PARTNERS OF NETWORK Ha Noi Architectural University University of Architecture Ho Chi Minh City Vietnam Association of Architects (VAA) IBA Study House (International Building Exhibition) Fraunhofer-Institutes ISE, IVI, IKTS City administration of Cottbus Wilde Metallbau GmbH PonSys GmbH 26

27 SUPPORTED ACTIVITIES Exchange of scientific results Organising seminars, forums, workshops of floating buildings Preparing special literature of floating buildings Making fieldtrips in floating villages to collect database for discussion in the seminars, forums, workshops Participating in Vietbuild construction international fair exhibition corporation Adaptation to local conditions Water chemistry and parameters Outdoor climate components Protection of environment Usage of traditional architectural elements 27

28 SUPPORTED ACTIVITIES Activities with partners: Planning and processing for innovative projects Organization of the 4th conference of Floating Architecture, cooperating with Graduate Research School of BTU. Exchange scientists, planners and students Architectural competition of floating buildings for students. Successful teamwork of future challenges 28
