Goal and impact
The Heat Stress module provides insight into the perceived temperature (PET), wind and the effect of shade at different times of the day. The module is used to map heat stress in urban areas on hot days, for example for climate stress testing. Both the current situation and a possible future scenario based on, for example, an urban development plan can be modelled. 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 the living environment to be modelled in full at hyper-resolution for aspects such as flooding, heat stress, air quality and noise. The Heat Module has been developed in accordance with the guidelines of the Delta Plan for Spatial Adaptation (DPRA).
Considerations
It focuses on climate, so we want to use it to calculate wind circulation and heat stress in the neighbourhood.
Human intervention
The calculations are carried out without human intervention. The results provide guidance, but are not decisive.
Risk management
Legal basis
The software can be used by local authorities and provincial authorities, amongst others, for: *The Environment Act: granting of planning permission, planning *The General Administrative Law Act (AWB): monitoring hazardous situations in which the competent authority ensures compliance with the general principles of good governance - Due care - Transparency - Proportionality

Data
By default, open data sources are used to build the virtual 3D environment in which the calculations are performed, 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 the KNMI is used in the Netherlands. Not all data sources are necessarily used in every calculation; this depends partly on the chosen location and the type of calculations. Users can also add their own data to the algorithm, such as green space data. User-added data is not included in this overview.

Technical design
This method allows a standard heat map showing the perceived temperature on a hot day to be calculated on the basis of a physical model. This model takes into account factors such as leaf cover, sky view, shade, radiation and weather data (wind and temperature). The calculation method has been tested against a range of measurement data for the city of Wageningen. The method was developed by RIVM in a consortium with, amongst others, WUR and HvA, and is described by RIVM in this report: https://www.rivm.nl/bibliotheek/rapporten/2019-0008.pdf. How the approach outlined in this report has been implemented in the software 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 14th of May 2025, at 13:08 (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 19th of June 2025, at 12:38 (CET) | Publication Standard 1.0
