Cool colours for hot cities - we have set ourselves the goal of transforming public squares and urban wastelands into meeting places with a high quality of stay.
The focus is on understanding public spaces as socio-cultural places and giving them a higher quality of stay. There is a lot of unused potential in cities and municipalities: outdated squares and passages as well as streets and squares that can be used temporarily as a result of the traffic turnaround.
The possibilities are manifold: by using colour, super graphics can be designed permanently or temporarily. This means that not only entire squares can be remodelled in the long term, but also small and large areas in the short to medium term.
Public spaces characterise our cities and communities. They are places where people of different origins, cultures and ages come together. Here, people can engage in dialogue, exchange ideas and pursue joint activities.
Involving citizens in wall and floor painting projects can be an effective way of doing this. This is where people come together and share their experiences - which, in the best-case scenario, can also contribute to breaking down barriers and developing a more tolerant society.
HEAT ACTION PLAN
A colourful and large-scale design has many positive aspects, including positive effects on the local climate. The so-called solar reflectance index (SRI) is a measure of solar reflectance and can be used as an indicator of how hot a material gets when exposed to the sun. The lower the SRI value, the hotter a material becomes when exposed to sunlight. Black (asphalt) surfaces, such as those found in many cities and towns, absorb heat radiation instead of reflecting it, which leads to higher local temperatures.
Light colours in general, and yellow, white and green shades in particular, have a high SRI value, reflect solar radiation and thus contribute to moderate temperatures.
