It also calculates subcategories relevant for the biotope area factor. The calculation module was developed within Ecodistr-ICT project and was programmed by <a href="https://www.sp.se/en/Sidor/default.aspx" target="_blank">SP Technical Research Institute of Sweden</a>.</strong> [box] <strong>KPIs (outcome) </strong> • Stockholm Biotope Area Factor (GYF), [-] • Biodiversity ratio, [-, %] • Social value ratio, [-, %] • Climate adaptation ratio, [-, %] [/box] &nbsp; <strong>The GYF methodology and what it does</strong> The biotope area factor (BAF) was originally developed in the 1990s in Berlin, Germany to increase green space in the city. It has since been further developed at other locations including the city of Stockholm (here referred to as GYF, Grönytefaktor). This module calculates the biotope area factor of a district, i.e. the area portion of a plot of land that serves as a location for plants or assumes other functions for the ecosystem, in relation to the total area of the plot, in accordance with the model developed in Stockholm, Sweden. The methodology, however, can be used in other cities as it is not dependent on site specific conditions related to the origin city. It was developed to illustrate ecosystem services and encourage the strengthening of local ecosystems and creation of climate-adapted courtyards with high social values. Planners, architects and developers received a concrete planning tool adapted to their way of working, which facilitated and inspired planning and design with ecosystem services. The Stockholm GYF methodology is a more advanced tool compared to the Berlin BAF tool. It includes many more input parameters and investigates multiple aspects of urban green. The input required is more detailed and will take some time to investigate and collect whereas for the Berlin BAF this is a more simple procedure. Stockholm GYF will, however, provide the user with much more information on urban green and ecosystems in the district. <a href="http://ecodistr-ict.eu/wiki/berlin-green-module-baf/">Berlin Green </a>is a separate module which is also available in the <a href="http://ecodistr-ict.eu/idss-platform/">Ecodistr-ICT IDSS platform</a>. <strong>Areas of application</strong> The Stockholm GYF promote greenery that serves several functions, e.g. create green spaces for recreation, delay and purification of rainwater, provide shading and contribute to pollination, and for aesthetic purposes. The GYF is measured as a ratio of the eco-effective surface to the total surface of the district. The eco-efficient surface consists of all the green and blue areas within a district designed according to certain set requirements. Blue surfaces refer to facilities connected to an open storm water management, such as ponds, ditches and rain gardens. The results are presented as a ratio [-] of ecologically effective surface area to the total land area (district), and the targets should be set by the stakeholders. The GYF target value can vary and references to previous relevant studies should be investigated, normally a factor of 0.6 is used. However, any improvement to the existing GYF is important and even a small change will make a difference to ecosystem services in the area. <strong>Interdependence to other modules</strong> This calculation module is not interdependent to other modules. <strong>References and more information</strong> <ul> <li><a href="http://www.cocity.org" target="_blank">cocity.org</a></li> <li><a href="http://www.stockholmroyalseaport.com/sv/rd-projects/co-city/" target="_blank">stockholmroyalseaport.com/sv/rd-projects/co-city/</a></li> </ul> &nbsp; <strong>List of input data</strong> The input data used in the Stockholm Green calculations are listed below. All input parameters are not required to be filled in with the exception of “Total Land Area of Plot”. However, the more information that is supplied the more accurate the result. Some input parameters are described as contributing (sub-) factors (CF). These are surfaces within the district. To these additional (supplementary) factors (AF) can be added for individual elements or important functions. These, including integer data, are later recalculated to equivalent (ecologically effective) surfaces. This means that certain features can count towards several aspects multiple times and are therefore more important since they contribute to the calculated GYF for different input areas. The input parameters also contribute to biodiversity (B), social value (S), and climate adaptation (C). For more information and detailed description of all input parameters, see references above. <em>Table 1 Input data for Stockholm Green calculation module</em> <table> <tbody> <tr> <td width="262"><strong>Applicable to district</strong></td> <td width="76"><strong>Unit</strong></td> <td width="281"><strong>Explanations</strong></td> </tr> <tr> <td width="262">Total Land Area of Plot</td> <td width="76">m<sup>2</sup></td> <td width="281">This is the surface area for the district.</td> </tr> <tr> <td width="262">Unsupported ground greenery</td> <td width="76">m<sup>2</sup></td> <td width="281">CF.
