Currently, real estate investors do not have the tools to help them to assess the quality of the location where the property is or will be built. Some information is available from weather monitoring agencies. A second set of data can be collected by observation (for example, positioning of adjacent buildings).

The combined sun index data usually serve as a basis for the investment decision (property position, type and thickness of insulation, number, size and position of windows, arrangement of rooms, type of heating, heating devices, etc.).

Taking into account the 3D terrain configuration, the Sun Index solution will provide key information about the proportion (%), movement and direction (N, S, E, W) of the sun relative to the selected location at the daily / monthly / annual level. The solar index will be a platform (www.sun-index.com, in the making) that will be the first to capture world-wide data and the first to take into account the three-dimensional terrain configuration.
