  2. A Google spreadsheet add on which can be executed as Excel function like SUM (or any other familiar function) which can calculate simple characteristic how "green" the building's surrounding is.

The service allows users to estimate the “greenness” of a building's (asset’s) location. For this purpose, the area of green spaces is calculated using open sources of cartographic data. The ratio of this “green” area to the total area within the geometry is then calculated. Green space includes parks, flowerbeds, etc. The size of the area to be analyzed is determined by the radius (in meters).

Spreadsheet usage example

Use function =GREENDEX(P1, P2) with two parameters:

  • P1. First parameter, address as text. Example: Berlin, Neustädtische Kirchstraße 4-7
  • P2. Second parameter, radius for area in meters. Example: 500

How to understand is the obtained green value good or not

As is clear from the description of the indicator, it can vary from 0 to 100. But to understand how good a number is obtained for the selected asset, it is better to have statistics on several launches.

For example, using the greendex service the benchmark for Berlin was prepared:

On the map is shown green index evaluation for randomly chosen points in administrative boundaries of Berlin in buildings extent.

Histogram of green index values for Berlin:

In this way, the obtained value can be compared with other buildings in Berlin and it is possible to figure out whether it is "greener" than other objects.
