Topics proposed in Spring 2025
Topic25
What is a neighborhood? Scale of aggregation for alternative service provision
Which essential (daily) local services should be best provisioned at which scale: building, group of buildings, historical neighbourhoods, or simply a certain size in meters or number of people? âBestâ is here defined in terms of resource use, universal access, governance, quality of service and resulting quality of life, and ultimately as providing synergistic satisfiers. Focus on low density neighbourhoods: which could be developed and which demolished?
Project under the direct supervision of Sascha Nick
Topic33
How to transform existing buildings towards shared spaces?
Based on literature, identify successful and unsuccessful space sharing models, such as share kitchens, guest rooms, reception rooms, activity spaces etc. Summarize and propose new models designed to minimize m2 per person and facilitate shared activities, leading to higher wellbeing with less resources.
This topic, under the direct supervision of Sascha Nick, is specifically for architecture students.
Topic34
Material requirements for renovation of the Swiss habitat
In a broad renovation program for the Swiss building stock (energy efficiency, repurposing shared spaces), how much of the needed materials could be reused from old buildings destined for demolition? How will this reuse affect renovation practices?
Project under the direct supervision of Sascha Nick
Topic35
What is needed to reduce Swiss urban sprawl to its level of 1935?
In collaboration with Jochen Jaeger, Concordia University, who developed the âWeighted Urban Proliferationâ metric, estimate the effects of a renovation + space repurposing program focused on more wellbeing with less m2 per person, and demolishing poorly placed buildings. Analytical and/or GIS approach.

Topic44
Carbon footprint of European regions, exposure and vulnerability to the energy transition
The European Green Deal will impact the European regions differently, and there is a broad consensus that policies, in general, impact differently between sectors and geographical regions. Admittedly, the political resistance to climate policy tends to be more pronounced in countries that heavily depend on fossil fuel exports and have carbon-intensive energy systems or countries with ETS sectors that constitute a more significant part of their economy. Increasing regional inequality can intensify opposition against European policies and EU construction.
Considering that there is little information on the carbon intensity of European regions, the goal of this master project is to build carbon footprint indicators at the European level using the NUTS2 regional level that describes 242 regions and to derive from these indicatorsâ exposure and vulnerability risk again the energy transition. The primary data source will be the Eurostat database, and the work will take as a basis the existing work on this topic.

Topic47
Allocation of Global Carbon Budget to the Swiss Agri-food system
The Paris Agreement is a legally binding international treaty on climate change adopted by 196 Parties on 12 December 2015. Its aim is to limit the increase in the average global surface temperature to 2°C or even 1.5°C relative to pre-industrial levels, in order to avoid triggering severe climate change impacts. This means that the world population should not emit more than 250 billion tonnes of CO2 for a 50% likelihood of limiting global warming to 1.5°C, and 1 150 billion tonnes for 2°C. In 2022, the world population emitted about 40 billion tonnes of CO2, which leaves it with 6 years’ equivalent of its current emissions for 1.5°C, and 28 years for 2°C. In this regard, the European Court of Human Rights ruled that âthere had been a failure by the Swiss authorities to quantify, through a carbon budget or otherwise, national greenhouse gas emissions limitationsâ. Your role will be to study ways of dividing the global carbon budget and defining a fair share for Switzerland, and within Switzerland a fair share for the agri-food system. The ultimate aim is to contribute to the development of sustainable pathways for Switzerland, in particular for its agriculture/food sector.

Topic57
Hidden costs of agrifood commodities (cotton, cocoa, or meat)
True Cost Accounting for Food (TCAF) is a methodology that aims to quantify and monetise the hidden costs of agri-food systems, including costs related to environmental, social, economic and health impacts. This approach is being developed and deployed to change the relative price of food in favour of low-impact products and to steer demand towards healthier and more sustainable diets. For example, coffee can have hidden costs of up to $110/kg due to modern slavery, greenhouse gases, biodiversity losses, pesticides ingestion, etc. In this project, your role will be to assess and analyse the hidden costs in the value chain of a specific commodity such as cotton, cocoa, or meat production, in a specific context such as fast fashion, labelled versus conventional cocoa, and local versus imported meat. The results of the project will contribute to the following SNSF research project: From farm to fork and beyond: A systems approach to implementing real cost accounting for food in Switzerland. Depending on the product chosen, external partners may join the project.

Topic48
True Cost Accounting for Food – animal welfare
True Cost Accounting for Food (TCAF) is a methodology that aims to quantify and monetise the environmental, social, economic and health impacts of agri-food systems. Although there is no commonly accepted methodology, the impact on animal welfare is an indicator that often lacks quantitative measurement. The aim of this project is to study how to quantify and monetise the impacts of the agri-food industry on animal welfare, focusing on different production systems and different types of livestock. This involves (1) understanding the rationale behind the monetisation factors of the TCAF; (2) researching the data available for livestock in Switzerland; and (3) quantifying and monetising. The ultimate aim of this project is to contribute to the development of a TCAF calculator for Switzerland.

Topic50
What is « fair » inequality for energy, mobility, and housing?
As part of the SWICE project (sweet-swice.ch), the Swiss Fair Inequality Survey aims to investigate multidimensional « fair » inequality, focusing on developing consumption corridors for energy, mobility, and housing. The goal is to establish fair maximum consumption levels in these areas. The survey, comprising 15-20 questions and taking about 15 minutes to complete, will target 1,000 representative participants from French and German-speaking Switzerland.
This semester project involves support in preparing the survey categories and questions. The process includes reviewing relevant literature, conducting analyses, and utilizing mini-surveys to validate key elements. The ultimate objective is to ensure the survey effectively measures perceptions of fair inequality in the specified domains.

Topic52
The impact of noise pollution on the Swiss real estate market: new evidence
The impact of noise pollution on residential households is a highly debated topic in Switzerland. In the past decade, several cities have adopted and/or revised strict policies to limit such a disamenity. These policies can have an important impact on the real estate market, people’s choice of where to live, and how environmental factors in cities impact welfare. The goal of this project is to answer these two questions: Who is the most exposed to noise pollution in Switzerland? What is the impact of policies related to noise pollution management on the Swiss real estate market?
Project in cooperation with Prof. SĂ©bastien Houde, University of Lausanne
Topic53
Filling in data for OK Climat
Switzerland ambitions to become climate neutral by 2050, and each canton has set goals on how to get there. However, these goals are often vague and not easily understandable or accessible for the common person. OK Climat wants to make this information more accessible by providing reports on how each cantonâs and municipalityâs climate policy is progressing, and identifying areas where improvements can still be made (https://www.ok-klima.ch/fr/). To facilitate this process, as many indicators as possible are needed, and they should be calculated automatically for all cantons and municipalities.
The semester project aims to obtain information on climate topics automatically from public web sites, in particular information on climate-related subsidies. It should analyse the available information and produce a database containing information on subsidies in a structured form. Next, the data will be used to calculate several new indicators, based on the amount of the subsidies available to inhabitants and businesses.
Project under the direct supervision of Sascha Nick and Yvonne Winteler (OK Climat); a more detailed project description is available.
Topic54
Decarbonizing the Building Sector in Switzerland
The building sector accounts for 24% of Switzerlandâs greenhouse gas emissions, mainly due to fossil fuel use for heating and hot water in homes and commercial spaces. Achieving carbon neutrality by 2050 will require a major shift: most buildings will need enhanced insulation, and fossil fuel-based heating systems will need to be replaced by sustainable alternatives like heat pumps, wood, geothermal systems, and district heating.
This project invites students to dive into Switzerland’s and the cantons’ strategies to decarbonize the building sector. Key tasks include: (1) Reviewing literature and decarbonization scenarios: Investigate established decarbonization pathways, such as those outlined by Swiss federal agencies and cantonal climate plan. (2) Integrating findings into an online calculator: Integrate your research insights into an existing web-based tool that models Switzerland’s decarbonization progress across various sectors.
Through this project, students will gain hands-on experience with Python programming and a practical understanding of how decarbonization scenarios are designed and applied in real-world policy contexts.

Topic55
The Future of Aviation
In 2021, the International Air Transport Association set an ambitious target for airlines: net zero emissions by 2050. Meeting this goal relies on a mix of efficiency gains, biofuels, and new hydrogen and electric aircraft. Yet, with biofuels currently below 0.1% of aviation fuel and no commercial airline using hydrogen or electric planes, the path to decarbonizing air travel looks challenging – especially as demand for flights is projected to keep rising.
This project will explore the limitations of aviationâs decarbonization strategies by examining biofuel capacity and the readiness of hydrogen and electric planes. Given these constraints, how much will we need to scale back air travel to achieve a sustainable future in 2050?
Integrate your research insights into an existing web-based tool that models Switzerland’s decarbonization progress across various sectors, refining the projections specifically for the aviation sector.

Topic56
Life cycle assessment of tiny houses
Tiny houses, light houses, micro houses are different names for residential buildings that are much smaller than standard single-family houses (max 40 m2), often energy self-sufficient and can be moved without leaving permanent marks on the ground. With these qualities, one expects that their environmental footprint (grey and use energy, materials, etc.) must be much smaller than that of standard houses, but by how much. This project is about comparing the environmental impacts tiny houses with those of standard houses in Switzerland.
