General

What is the Heat risk indicator?

The heat risk indicator calculates a metric for the risk to vulnerable citizens due to heat stress. It correlates information on residents 65 years old from CBS data which is a Dutch dataset, the Heat stress Overlay and the amount of new build houses. In this indicator it is assumed that new build houses have better isolation and therefore facilitate better heat retention. This indicator is for example useful for projects in where:

  • heat stress and the effect on citizens is measured
  • livability plays an important part

Indicator panel

The indicator panel (see the image on the right) shows in a table per neighborhood:

  • the neighborhood name
  • the average heat stress
  • the amount of elderly people (65 years and older) and the total amount of people living in this neighborhood
  • the amount of elderly people that are living in new build houses
  • the risk assigned to this neighborhood. The higher the number, the higher the heat risk is.

Calculation

First the heat stress in an area is calculated. For more information about this calculation, read the following section. More heat stress is a greater risk. Then the amount of people of 65 years are counted for each neighborhood. If there are more elderly people living in a neighborhood, there is a greater risk. The amount of houses after 2012 are counted as new build houses. The newer the houses are, the greater the risk. The risk is then calculated as: risk = Percentage elderly people x the heat stress in degrees.


Score

The score is represented in a progress bar, with a scale from 0 to 100%. Determine if you want to calculate the absolute or reative score. The higher the score, the less heat risk for the elderly there is.

Additional configurations

For this indicator to function, only the heat stress overlay has to be added to the project, see below for the steps. However, due to the reliance on CBS data which is a dataset for the Netherlands, the indicator will only function on projects located in the Netherlands.

Add the Heat stress overlay

When the indicator is added to the project, an error message can be given. This is due to the missing Heat stress overlay in the project. Read below on how to add this overlay to the project.

Heat risk (Indicator):
  1. Select in the editor 'Geo Data' from the ribbon
  2. Select 'Overlays' from the ribbon bar
  3. Select the Heat stress overlay from the drop down menu
  4. Click on the tab Indicators and the button Indicators and choose for Reset to Start values (faster) to update your project.
