Heat Stress Tool

Nelen & Schuurmans' heat stress tool helps reduce urban heat stress. Users can map areas, test measures, and see effects instantly. It performs quick calculations, is user-friendly, and accessible via any web browser without additional software.

One of the main advantages of the heat stress tool isthat it allows for the practical application of scientificheat stress calculations. With the heat stress tool, it isnot only possible to perform these calculations quicklyand easily for a specific area, but also to quantify theimpact of various measures. Therefore, the heat stresstool can make a significant contribution to policies andmeasures regarding heat stress.
Secondly, the heat stress-tool is very easy to use. It isaccessible through any web browser and does notrequire any additional software. Therefore, the tool canbe used on every computer or tablet with a workinginternet connection and browser.
Thirdly, no specific skills or knowledge are required foruse of the heat stress-tool. The user interface of the toolis very easy to understand and to use. As a result, theheat stress tool is not only useful for experts butespecially for those without specific knowledge aboutheat stress. It can be utilized as a tool by policymakersor, for instance, as a means of communication towardsthe public.

- The heat stress-tools supports in quantifying the effects of heat stress
- The resulting maps from the heat stress-tool provide a basis for further analysis of heat stress in a specified area
- The heat stress-tool supports decision-makers to decide which heat stress-reducing measures are most effective, by enabling the quick simulation of ‘what if’-scenarios
- Through its visually attractive and understandable interface, the heat stress-tool is an ideal instrument to use in stakeholder sessions, community-based and participatory efforts and broader communication outlets.
Heat stress tool addresses heatwave problems.

TRL6. Prototype system verified
At this moment, the heat stress tool has been developed to the extent that it is a fully operational tool in the Dutch context. For the Dutch context, the heat stress tool is at TRL 9. However, this will be the first time that the heat stress tool will be employed in an international / Greek context. Therefore, in this specific context, the TRL is at level 6. Following the development of the initial version of the heat stress tool, it underwent testing by various users. The feedback from these initial users was utilized to further develop and enhance the tool in various ways. This has resulted, among other things, in an improved user interface of the tool. Additionally, the underlying calculations of the tool have also been enhanced, making the tool even faster in the most recent version. The heat stress tool is currently being used by various organizations in the Netherlands and is fully operational in the Dutch context.

How does it work?

The heat stress facilitates the city’s decision-making capacity because the heat stress tool provides decision-makers for the city of Athens with a tool to obtain more insight both into the expected effects of climate change on experienced heat stress and into the effect of different mitigation measures. This provides the city’s decision-makers with the insight and quantitative basis to make decisions on how to deal with heat stress, now and in the future.

The development of the heat stress tool took place in multiple stages. Initially, the first stage involved conducting preliminary tests and analyses using the heat stress calculation method developed by Wageningen University. The Geoblocks application was independently developed by Nelen & Schuurmans. Subsequently, in the second phase, the initial version of the heat stress tool was created together by using the Geoblocks application with the heat stress calculation method and a couple of use cases at 5 different Dutch municipalities. In this stage, different heat stress experts, software engineers, and UX designers were involved to design and develop a user-friendly and interactive interface for the heat stress tool. This phase, along with subsequent iterations to enhance the heat stress tool with end users, formed a part of the IMPETUS project. The developmental expenses incurred during these stages were partially covered by funding obtained through this project, with the remaining costs financed by Nelen & Schuurmans.

Like any model, the quality of the results from the heat stress tool relies on the quality of the input data. The primary input data for the heat stress tool includes a high-resolution Digital Elevation Map (DEM) and a high-quality vegetation map of the area of interest. The elevation map should also include the height of buildings and trees to account for their impact on the experienced heat stress. Ideally, the DEM should have a resolution of 1 to 2 meters. Furthermore, a high-quality vegetation map is essential for the incorporation of the cooling effect of vegetation on the experienced heat stress. It is possible to develop the heat stress tool for an area where less accurate input data is available. The heat stress tool can still be an important and effective resource, provided that the user is aware that its results entail greater uncertainty (we always communicate the level of uncertainty with the presentation of the model itself).
