Goal and impact
The Heat Stress module provides insight into the wind chill factor (PET), wind and shading at different times of the day. The module is used to map heat stress in urban areas on hot days, e.g. for climate stress tests. Both the current situation and a possible future situation based on an urban development plan, for example, can be calculated. This is a physical model, the approach does not rely on artificial intelligence. The Heat module runs on a broader platform for data integration and simulations, which enables integrated calculations of the living environment at hyper-resolution for aspects such as flooding, heat stress, air quality and noise. The Heat Module was built according to the guidelines of the Delta Plan for Spatial Adaptation (DPRA).
Considerations
Focused on climate and so we want to use it to calculate wind circulation and heat stress in the district.
Human intervention
Calculations are made without human intervention. The results provide direction but are not decision-making.
Risk management
Legal basis
The software can be used by municipalities and provinces, among others, for: *Environment Act: licensing, planning *AWB (General Administrative Law Act): Monitoring dangerous situations where competent authority ensures General principles of good governance - Carefulness - Transparency - Proportionate consideration

Data
By default, open data sources are used to build the virtual 3D environment in which calculations are made, such as the BAG and the BGT: https://support.tygron.com/wiki/Project_Sources#Sources_connected_to_the_Tygron_Platform.
For weather data, open data from KNMI is used in the Netherlands. It is not always the case that all data sources are used in all calculations, this partly depends on the chosen location and the type of calculations. Users can also add their own data to the algorithm, e.g. green data. Self-added data are not included in this overview.

Technical design
Using this method, a standard heat map with wind chill temperature on a hot day can be calculated based on a physical model. This model takes into account factors such as foliage, sky view, shade, radiation and weather data (wind and temperature). The calculation method was tested on a set of measured data for the city of Wageningen. The method was developed in a consortium by RIVM with WUR and HvA, among others, and is described by RIVM in this report: https://www.rivm.nl/bibliotheek/rapporten/2019-0008.pdf. How the approach has been translated into the software in this report is described here: https://support.tygron.com/wiki/DPRA_Heat_Module

- This is used for climate stress tests and provides insight into wind chill, and how it can be influenced. This is determined from different elements such as foliage, shade and wind, which can be analysed separately. As a result, the module also provides tools for wind, shade and sun angle analyses.Last change on 4th of June 2025, at 12:06 (CET) | Publication Standard 1.0

- The algorithm uses sensor data to make a calculation for predictions of slipperiness risks. These predictions are used to determine where to grit (preventively), in consultation with meteorologists. In addition, the algorithm can issue various alarms, for example when there is a chance of wet road sections freezing.Last change on 10th of July 2024, at 8:18 (CET) | Publication Standard 1.0
