In very densely populated cities like Zurich, the many buildings have an immense impact on the city's climate and the environment. Based on this knowledge, we see it as important to think about the previous construction of buildings.
In our project we would like to show the difference between the building material and the surface of different buildings. We investigate and compare common building materials with each other, as well as different possibilities of surface texture. From this, we create two models which are the best and worst combination and what differences they represent for the climate. The focus is on the lifecycle of the different building materials and the resulting consequences for the environment and climate.

We want to use a calculation to evaluate how many trees are necessary to make a city like Zürich CO2 neutral.
- What kind of trees convert the most CO2 into oxygen?
- How long does it take a tree to convert the full amount of CO2?
- Costs of 1 Three?
- How much space does a tree need?
- Is the number of the trees possible to compensate the whole CO2 emission?
- Is the number of trees required realistic in relation to the amount of space in a city?
We will illustrate our results with a benefit analysis and will explain it in a report. à (Costs, amount of space required, Purchase price, service costs needed)
We will make a survey with random people, friends, and our classmates. à About the CO2 emission per person.
We plan an interview with a person from an organisation, which want to plant trees or to regulate the CO2 in the air over Zürich.
- How much money it will cost, to make a city climate neutral
- What are the main goals?
- When should the target be reached?
- What are the possibilities?
What exactly is the effect that the group wants to trigger with your action?
We want to give people an understanding of the diversity of trees and which trees are in danger in the city of Zurich. We will explain what diseases exist, which trees are involved and what the outcomes are. We also want to show how bad it can be when foreign plants come to Switzerland and make people aware that no foreign plants should be planted.
What are the means by which the intended effect should be achieved?
We want to share facts and knowledge and encourage people to take a look around the city of Zurich themselves and maybe have a closer look at the plants in their own garden. Maybe we will make an interview with an employee form the "Stadtgärtnerei Zürich".
How should the effect be achieved?
Through facts and knowledge from experts. The website from the city of Zurich has a lot of information about this topic and is very interesting and useful.
Who is the target audience?
Everyone, because everyone is affected. We all need trees and plants to live and it doesn't hurt to look after your plants in your own garden.

In Our Project, Naomi and I would like to know more about the coral reefs.
Land plants only produce 1/3 of the oxygen we breathe, the rest comes from the ocean. The dying of the coral reefs affects all species from marine life to human kind. We would like to to do a comparison to a City Tree in Zürich and calculate the amount of oxygen which is produced by the tree compared to the corals in the ocean. Further we would like to get to know more about how exactly corals affect us and the air we breath. Another aim is to get in touch with an Organisation who deals with replanting of corals and the restauration of coralreefs. We also thought about covering some other questions. For example how to prevent all coral reefs from becoming extinct by 2050, or is it possible to restore the riff like before and are there any statistics that show how the reef is doing at the moment?
What is our goal and how it can be achieved?
What exactly is the effect that the group wants to trigger with your action?
- We would like to bring urban gardening closer to people and introduce them to this type of gardening. We want to use this type of gardening to bring green spaces back into the cities.
With what methods should the intended effect be achieved?
- In order to achieve these goals, we would like to ask the inhabitants of the cities what they know about this topic and, if necessary, inform them. For this purpose, we would also like to give them a prospect, which we have produced ourselves. It will give them a short summary of what urban gardening is and how they can make the cities greener. Maybe we can also do an interview with a shop manager or with the city of Zürich.
How we can achieve our impact?
- With various opinions and advertising, we would like to make our target audience aware of how everyone can bring a little green, back to the cities themselves.
Who is the target audience?
- People who live in the city, as well as teenagers, adults, and senior citizens.
