Heat risk (Indicator)

What is the heat risk indicator?

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

• heat stress and the effct on citizens is measured
• livability is an important goal

Calculation

First the heat stress in an area is calculated. The warmer it is in an area, the more risk there is. Then the amount of 65 year and older people are counted for each Neighborhood. The more elderrly people there are, the more risk. The amount of houses after 2012 are counted as new build houses. 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%. The score is calculated on the

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.

Overlays

When the indicator is added to the project, an error message is given. To solve this, the heat stress overlay has to be added.

How to add the Heat stress Overlay:

1. Select Geo data and then Overlays in the ribbon header
2. Select the Heat stress Overlay from the hover panel.
