With this design tool it is possible to carry out introductory calculations on your application in which the hard surfaces interact with storm water designs. The knowledge developed within the Vinnova financed projects “Grey green system solutions for sustainable cities” and “Climate secured system solutions for urban areas” has been integrated in the design tool.

The tool is intended to be used for introductory calculations before detailed planning is started, which means that it has some limitations. There are also some features missing due to restrictions in budget and time within the projects. Here are some bullets on limitations and identified needs for improvements:
