The indicator works with several global variables. This can be done by selecting Indicators -> Globals -> Add Global. The following global variables need to be added manually to the project:  
*Global: RESIDENT_PER_HOUSE: This global variable indicates the number of residents in a house per selected project area. The recommended value for this variable is 3 residents per house.
*Global: GREEN_HEALTH_EFFECT_1KM: This global variable indicates the effect that green (public green space, park, garden, public square, etc..) has on the health of the citizens with a DALY value for green in a radius of 1km. The recommended value for this variable is 0.000246 according to Hoeymans et al. (2007); Maas et al. (2008).

General

What is the Health indicator?

The Health indicator on the Tygron Platform is an indicator that calculates the effect of the green space on the health of the citizens living in a specific neighborhood and the value of the health effect that green in the selected neighborhoods has on nearby residences. This indicator is a simplified version of an RIVM calculation model.

Calculation

Score

The score is based on the amount of DALY( Disability-assisted life years) realized in the project area due to present green spaces. The additional life years are also assumed to have a monetary value because they help with savings in the healthcare. The effect of green on the health of the citizens in the project area is visible as the score of the indicator. For each neighborhood the effect of green on the health of the citizens in that neighborhood is determined and an average of all results is calculated for the final score. Determine if you want to calculate the absolute or relative score.

Additional configurations

A set of areas need to be loaded based on the neighborhoods in the project area. The areas should have the attribute CELL_ID, which has a value of the ID of the neighborhood it was based on. The project space is split into three different areas: the core area, the 1km buffer area (a set of areas that should represent the neighborhoods that are buffered with a radius of 1km) and the 3km buffer area (a set of areas that should represent the neighborhoods that are buffered with a radius of 3km).

Add the Attribute

The indicator also uses the attribute GREEN_M2. This attribute indicates the green space per m2 in a specific area. The functions that use this attribute can be found in the Function Values table by selecting Indicators -> Function Values and selecting Environment in the group filter. The GREEN_M2 attribute can be modified for each function separately according to the needs of the project.

Add the Global

The indicator works with several global variables. This can be done by selecting Indicators -> Globals -> Add Global. The following global variables need to be added manually to the project:

  • Global: RESIDENT_PER_HOUSE: This global variable indicates the number of residents in a house per selected project area. The recommended value for this variable is 3 residents per house.
  • Global: GREEN_HEALTH_EFFECT_1KM: This global variable indicates the effect that green (public green space, park, garden, public square, etc..) has on the health of the citizens with a DALY value for green in a radius of 1km. The recommended value for this variable is 0.000246 according to Hoeymans et al. (2007); Maas et al. (2008).
  • Global: GREEN_HEALTH_EFFECT_3KM: This global variable indicates the effect that green (public green space, park, garden, public square, etc..) has on the health of the citizens with a DALY value for green in a radius of 3km. The recommended value for this variable is 0.000078 according to Hoeymans et al. (2007); Maas et al. (2008).
  • Global: MONETARY_VALUE_DALY: This global variable indicates the disability-adjusted life years monetary value. The recommended value for this variable is 87000 according to Stassen et al. (2007).
  • Global: INDICATOR_START_VALUE: This global variable indicates the start value of that should be attributed to the initial situation. The recommended value for this variable is 0.5. With this initial value, the target needs to double the amount of particulate matter.

Note that this is only an example of the values that can be entered for each of the global variables. These values can be modified and changes according to the needs of the project.
