Housing target (Indicator)

From Tygron Support wiki
Jump to navigation Jump to search

The Housing target indicator calculates the number of houses that are added to the project current situation and relates this to the total target of houses. This indicator is useful for projects where for example:

  • one of the goals is to work on reaching a certain housing target
  • different spatial plans are compared using the 3D Visualization

The total amount of houses is adjustable, this makes it useful for all types of projects. The housing target indicator is on neighborhood level.

This Excel indicator can be downloaded from the Public GeoShare. Read on to find out more about the indicator's calculation method and how to set it up in your project.

Indicator panel

The indicator panel shows the three different types of housing, the number of houses that are built in the neighborhood and the targets for the social housing and the total target.


The indicator calculates the difference in houses between the planned and original state of the project. Houses in the Tygron Platform are called Units. A building block is not necessarily one unit. You can see the number of units when clicking on a building in the 3D Visualization. Only units of the type normal, social and luxe are being taken into account. The total target can be adjusted. An additional target of 30% social housing is deducted from this total target.


The score is represented in a progress bar, with a scale from 0 to 100%. Determine if you want to calculate the absolute or relative score.

Additional configurations

For this indicator to function, an extra attribute has to be added to the Neighborhood in where the houses will be build and a new Global has to be defined to set the total housing target. Read below for the steps.

Add the Attribute

The indicator looks only at the number of units in a certain Neighborhood. This neighborhood is marked with the attribute PLAN_AREA with a value > 0, for the indicator to know which neighborhood to look at. Therefore, an attribute has to be added to the neighborhood in where you want to build houses.
