Aim and scope of the program Young students and professionals in Tunisia should be well trained to deal with the imminent risks facing the country and the region. Environmental and socio-economic risks that appeared as a direct result of climate are one of the biggest challenges facing the country and the region.

Creating a new green economy in Tunisia can help the country in facing the climatic and economic challenges of the future.

One of the most effective ways to rapid the progress in the country is to provide high quality education to the youth. Education in the field of sustainable design is especially important due to the challenges facing the countries which were mentioned above. In this context, the aim of this project from the institute of Sustainable and Energy Efficient Design and Building at TU Munich is to provide training on energy efficient design and buildings to young architecture students, while creating sustainable connection with the Tunisian partners for future collaboration.

The two-weeks summer school was to promote the knowledge of energy efficient and sustainable buildings design and to provide training for Tunisian students of architecture. The program consisted of lectures, discussions and workshops on the fundamentals of energy efficient building design. Lectures introduced concepts and recent applications and techniques for energy efficient buildings and advancements of the recent scientific researches and projects.

The participants were encouraged to form and present their ideas, results and what they learned in the form of innovative low-energy building designs that respond to both climatic

conditions and sociocultural aspects. The students carried out their work under the supervision of the instructors who gave feedback and evaluated the work at the end of the workshops.

In cooperation with École SupÊrieure d'Architecture, d'Audiovisuel et de Design (ESAD) and National School of Architecture and Urbanism (ENAU), the summer school was provided by Professor Werner Lang’s chair of Energy Efficient and Sustainable Design and Building. The Institute is a joint appointment between the Faculty of Architecture and the Faculty of Civil, Geo and Environmental Engineering in the Technical University of Munich.

For more details on the program structure, please refer to the attached booklet and flyer in annex 01.

Summer school progress The program of the summer school was carefully designed to ensure the delivery of knowledge and to function as a mutual collaboration rather than a one-sided setting.

Lectures As planned in the summer school outline, several lectures with focus on the summer school topic were provided to the students. This included keynote lectures by Prof. Werner Lang (TUM) and representatives from the Local Tunisian institutions in the opening day. TU Munich team has provided several lectures in the first week of the summer school to pass the knowledge forward to the students and to introduce them to the principles of sustainable building to be adopted in the design projects. Faculty members from TUM and the Tunisian partners delivered lectures on different topics related to sustainable and energy efficient design such as: - The fundamentals of energy efficient building design, - Design strategies and tools for high-performance facades in hot-arid and hot-humid climates - Case studies from previous successful projects.

- Life-cycle analysis and interdisciplinary design projects - Recent trials in energy efficient design and building in Tunisia - Current and future building efficiency codes and rating systems in Tunisia - and the use of Numerical and simulation tools in designing energy efficient buildings.

Assignment The Student were assigned on design project intended to serve as a cultural center for the island of Djerba. The project aimed to promote and spread the culture and heritage of the 3

island, with special focus on the island’s architectural authenticity. The main design objective was to introduce an architecture that responds to the local climatic, socio-cultural and urban context.

The project is planned to be adopted by Djerba Association for Sustainable Development, it is potentially an achievable project. It can be built in the future through funding from local businessmen and members of this association. Therefore, in addition to reacting with passive strategies to the local climate, aspects of economy and energy efficiency should be considered. Design projects should consider that they will be constructed one day.

The students worked in daily workshops under the supervision of TUM and Tunisian faculty members to develop their own designs and ideas for a cultural center in the island of Djerba in Tunis. This project was chosen because of the vernacular and cultural heritage of the island and the possibility to and rationalize the students designs and ideas and include them in the final building design which will be built with the support of local community. An excursion to an eco-village in Tunis (GDA Sidi Amor) was also organized where the students had the chance to observe different vernacular buildings and construction methods in an integrated socio-economic sustainable village.

During the summer school, the students presented their work and ideas to discuss and enhance their projects. And finally, they presented their final designs at the end of the summer school for final Jury.

Programm Students were divided into 5 groups of 5 to 7 participants in each. Each group worked as an interdisciplinary team to fulfil the holistic design purpose that includes the following topics: -

Architectural design Energy concept Building construction Building Physics Ecology and Life Cycle Assessment Economics

Every design project came up with its own vision of sustainability that introduce an integral approach to climatic responsiveness and contemporary interpretation of the local architectural typology.

Workload According to the workshop schedule, the students presented their work on two stages: During the first week, a conceptual 4

frame work including schematic design and preliminary passive design strategy were introduced through two group presentations. Under supervision and consultation of the lecturers (both from TUM and local institutes), each group developed their design and presented the final project by the end of the second week of the workshop.

Language All materials for the project were prepared in English.

Presentations were given in English.

Consultations were offered in English and Arabic.

Consultation All participants worked on an integrated design that focuses on energy efficiency, sustainability and passive design. The students were supervised by the Institute of Energy Efficient and Sustainable Design and Building of the Technical University of Munich in cooperation with participants from the local institutes.

Summary of the achieved goals The summer school was successful and achieved its main goals: 1. Providing high quality training for young Tunisian students in the field of energy efficient buildings: The lectures and workshops introduced the students to the field of sustainable design and energy efficient buildings.

From the progress of the students’ deliverables it was noticed that they successfully acquired the new knowledge and utilized it in an effective way to produce a well-developed final product.

2. Promoting the concept of sustainable design The summer school got the attention of a wider audience by being well presented in two of the largest architecture institutes in the country as well as being interviewed by a specialized Tunisian magazine (Archibat). The positive response that the summer school received from the local faculty including the participating students supports the possibility of future collaboration in that field.

3. Establishing future collaboration The German and Tunisian partners reached a mutual agreement on the possible shapes of future collaboration. Both sides showed their interest in working together on more optimistic projects such as developing a joint master program in the field of energy and sustainable design.

Recommendations/proposals for future activities A meeting between the German (TUM) and Tunisian partners (ENAU and ESAD) was held on the office of Dr. Najla Allani, director of the ENAU, to discuss the shape and opportunities for further cooperation. The meeting participants were: From TU MĂźnchen: Prof. Werner Lang (Chair for Energy-efficient and Sustainable Design and Building, TUM), Dr. Wael Mousa (Postdoc, TUM) M.Sc. Mahmoud Gadelhak (PhD candidate, TUM) From the Tunisian institutes: Prof. Najla Allani (Director, ENAU), Prof. Mouldi Chaabani (Director, ESAD), Dr. Ismail Haddad (Director, Department of partnership, Tunisian Ministry of Higher Education and Scientific Research), Dr. Kabil Fekih (Faculty member, ENAU and ESAD) Dr. Monia Ourfelli (Faculty member, ENAU and ESAD) Several ways of cooperation were discussed, which includes the following according to their impact: 1- International Master Program (120 credits, full-time) The collaboration project with the highest economic and academic impact is to establish an international master program (2 years, 120 credits). It could be established in close cooperation between TUM, ENAU and ESAD. While TUM might represent the European side, the Tunisian universities might represent North African countries. The international joint master program might focus on sustainable design in different regions and climates, covering hot and dry, hot and humid, moderate, and cold climates. The master is intended to be set up in an interdisciplinary way, including Architecture, Civil and Environmental engineering and Mechanical engineering. This requires an interdisciplinary set up of teaching faculty which will be supported by TUM, ENAU and ESAD and partner institutions. The general concept is to divide the teaching modules amongst the partners which gives the students the chance to be exposed to the rich cultural and economic situation of the participating universities and their countries.

Scientific impact: with an overall teaching load of 120 credits (3600 working hours) the master program allows for acquiring of a wide knowledge at a high scientific level. The graduates achieve a high degree of knowledge which can be applied in scientific research, research related teaching and research and development in the scientific field and the industry. Furthermore, it can be expected that these candidates can pursue their

6

research with regard to doing a PhD, which will qualify them to become leaders in the field of sustainable development.

Economic impact: due to the high qualification of the graduates it can be expected that they will find future positions in the field of research and development, education, governance, industry, engineering firms, manufacturing, and construction companies. This will serve as a strong support structure of the development of a green economy in North-African countries. That way the thorough implementation of sustainable design and technologies will be supported on an international scale, as the program is open to international applicants from all over the world. As mentioned before due to the wide range of climatic conditions of the participating universities, the students will gain a thorough knowledge to apply technologies and knowledge to almost all climatic zones of our planet.

2- International Master Program (90 credits, part-time) This program could address the majority of the current workforce who is – in most cases- not familiar with sustainable design and building. Similar to the above-mentioned program, this master program might focus on sustainable design with an interdisciplinary approach. This master program could be designed to allow students to continue to work in the professional field while participating in the program which could be taught in a concentrated way (e.g. six days\month with assignments between the modules). This could give the students the unique opportunity to bring their professional experience to the coursework, and apply the acquired knowledge directly in their daily professional work.

Scientific impact: The scientific impact can be compared to the above-mentioned international master program with 120 credits. However, due to the limited credit hours, the knowledge gained will be more focused, which will affect the range of the topics being covered through the program. Yet, it can still be expected that the graduates will still be sufficiently qualified to conduct scientific work worldwide.

Economic impact: As mentioned above, this program would address the majority of the current workforce who is – in most cases- not familiar with sustainable design and building.

Therefore, depending on the teaching format and resources available, the economic impact can be very high. Due to the limited credit hours, the knowledge gained will be focused, which will affect the range of the topics being covered through the program. Due to the work-study situation and intense, almost simultaneous transfer of knowledge between education and practice, this program will not only have a positive impact

7

of the participating professionals but also on their work environment including their superiors and colleagues.

3- Study abroad program Architecture students at TUM are required to study a year abroad during their third year of study. In that context, TUM is already cooperating with almost ninety institutions worldwide.

The Tunisian partners could be included in this program were a few German architecture students can spend a year studying in Tunisia while the Tunisian students have the chance to study architecture at TUM. However, this is not geared towards sustainable design only but covers all fields of architecture education.

Similar to this established program it could be considered to create on a M.A./M.Sc. level related to sustainable design once a comparable design program is established at the Tunisian partner universities (ENAU and ESAD).

4- International workshop for students of TUM, ENAU, ESAD Based on the success of the current workshop, future workshops could include students from the three universities named above to work together on a joint (possibly design\build) project. This could be started by a field trip with students from TUM in Tunisia, possibly in March 2018.

Such an international workshop will allow German and Tunisian students to learn from each other as much as from their teachers. Furthermore, international networks will be created and supported. Through the dissemination of the results other students as well as faculty and the wider public will gain insight to intercultural design work. Through the option of design built project the experience can be extended through the execution of real project. This will give not only hands-on experience to the students but also support the local culture in the field of sustainability, and creates case studies which will be published and experienced by a wider international audience. During the current workshop, two potential sites were investigated (Djerba and sustainable village) to be dealt with in the near future.

5- Joint Research projects Future research projects related to sustainable design can be an option for scientific research collaboration of the three universities involved.
