Waag Open: keep your head cool (moved to August 24)

It's getting hot in here! Since 1923, the KNMI (The Royal Netherlands Meteorological Institute) measured 28 heat waves and almost half them occurred in the past 20 years. If this trend continues, the number of 'tropical' days (days above 30 degrees) will have doubled by 2050. 

But what are the consequences of these heat waves in people's homes? In countless Dutch (rental) homes, bedrooms heat up considerably in summer. And that can lead to physical and mental complaints: heat stress. But what does this actually mean?

Lisanne Corpel, researcher at the Hogeschool van Amsterdam (HvA), shares her knowledge on measuring heat and the phenomenon of heat stress. She conducted a study on heat around Nieuwmarkt in Amsterdam with, among others, residents of Flesseman nursing home.

During this summer evening, we will search together for solutions to keep our heads (and homes) cool. Do you have any good heat hacks or could use some tips of your own? Then come to this summer edition of Waag Open! 


19:30 - 19:45 hrs: Welcome by Sylke van Duijnen & introduction citizen science
19:45 - 20:00 hrs: Lisanne Corpel (HvA) on heat stress: what is it and how do you measure it?
20:00 - 21:00 hrs: Measuring heat yourself: on the road with sensors in the neighbourhood
21:00 - 21:30 hrs: Data analysis & drinks

About citizen science

In citizen science (also known as citizen sensing), citizens can use open source tools to measure their own living environment and learn to interpret these data. This is relevant because: 

  • As a citizen, you have ownership of your data
  • You create shared knowledge with experts and institutions 
  • Your action perspective is enhanced 

In this way, citizens' information position is strengthened, and they are in a stronger position when talking to policymakers. It also gives them tools to improve their quality of life. Think about the air quality in your street, noise pollution from traffic, the water quality of your favourite swimming spot or the heat in your house!

This summer, Waag Futurelab, together with Hogeschool van Amsterdam, TU Delft and VPRO, is investigating exactly how warm it gets inside. We are doing this in the Thermo-staat project where residents measure the heat themselves.

Waag Open

Waag Open is a monthly public programme focused on today's themes. We organise various workshops and present collaborations between scientists, designers and artists. Once a month, Waag opens her doors for programmes that can be attended by anyone and everyone.

Due to her monumental state the Waag building does not have elevators. A gender neutral toilet is present on the first floor.
