ICEtool is an all in one QGIS plugin to easily compute ground temperatures in an urban environment.
This allows you to make and highlight the urban design choices (e.g. vegetation, materials) that reduce urban heat island phenomena.
This plugin is based on the preliminary work made with ICE procedure (from Elioth and Egis VRM). In addition to being more user-friendly and fully integrated into a plugin, code has been completely rewritten, algorithms have been optimized and new features have been added.
ICEtool includes the shadow generator of UMEP QGIS plugin, thanks to UMEP team for all their work ! Check UMEP here.
ICEtool sources (for example for material database) are stored just here
To get started with ICEtool, ensure that QGIS Processing Toolbox is displayed (CTRL+ALT+T) and read the user manual in the Help menu of ICEtool.
How to use ICEtool ?
What does ICEtool take into account ?
Ground temperature is an estimation based on :
- : Heat flux related to radiation (from the sun, infrared radiation and the atmosphere)
- : Heat flux related to convection (considered as very low and homogeneous)
- : Sensitive and latent heat flux of water
- : Heat flow related to conduction
- : Heat flow related to thermal storage (thermal capacity of materials)
What is not included in the calculation ?
- : does not include the radiation from the reflection on building facades
- : The anthropogenic heat flux is not calculated, so neither the heat release from cars nor from air conditioners is evaluated.
And so, what are the consequences for ICEtool ?
As a consequence of these shortcomings, ICEtool cannot substitute itself to a real thermal simulation like the one that could be realized with envi-met for example. However, ICEtool is a good solution to easily obtain a good approximation based on a calculation performed on solid scientific basis.
