What are your experiences with energy-saving measures? Have you taken energy-saving measures at home or not?

Let us learn from you so that we can reduce the energy consumption in Europe even further. More and more people are deciding to renovate their house in a sustainable manner: for example with insulation, double glazing or by installing solar panels. You might be one of them. But it is also possible that you did not take any measures (yet) to reduce your energy consumption.

We’re not there yet…

If we can jointly reduce the energy consumption of existing houses and buildings – now responsible for about 30% of the total – we can make a big difference! Energy measures at home very valuable. It is therefore important for us to understand even better how we – as a municipality, government or European Commission – can best support and motivate people to take action. As part of the European project City-zen, TU Delft is investigating what are decisive factors for people to renovate sustainably or on the other hand, to not take energy-measures.

Would you like to help us further reduce the energy consumption in Europe?

The experiences and motivations of people like you, who can choose to renovate their house sustainably, but also to decide against this, are extremely important for our research. Would you like to help us reduce energy consumption in Europe by sharing your experiences with us via this online questionnaire? Your input is incredibly valuable! We hope we can count on your help!

You can fill in the questionnaire HERE. It takes about 15 minutes. Your answers will of course be handled completely confidentially and will only be used for research within City-zen. You can also copy the link below into your browser:


What is City-zen?

In City-zen, 25 parties are working together to learn how to make cities free of coal and gas. They are working with new technologies and see what changes are needed in the city, in regulations and in people’s homes. With this research we start to understand what motivates people to take energy measures in their home, but also why some measures are more attractive than others.

Thank you very much for your help!!

  • The Project

    A city operating entirely on clean energy. In theory, it's possible. But in real life? How to integrate new solutions in existing buildings, systems and people's lives? What are the technical, economic or social barriers? And how to overcome these? That's what we've learned by doing in 20 projects in Grenoble and Amsterdam.
