According to literature reviews, green infrastructure planning analyses are typically conducted using either an exact method or a heuristic optimization approach. In contrast, visual analytics have been demonstrated to be an effective tool for decision-making, particularly when dealing with complex and multivariate data. The siting of EVCS is one such example: the process of selecting suitable locations for EVCS involves GIS analysis, which can become exponentially complex due to the numerous parameters involved with multivariate and multiple-scale geospatial data used in the analysis. This notebook details the data preparation and analysis for each parameter selected for the use case study in the Dundee area. The datasets included in this notebook were chosen based on three sources: use-case scenarios, literature reviews, and existing regulations on EVCS siting.32:T844,html`

This means that the building is not very energy efficient and is likely using a lot of energy from sources that produce CO2 emissions, such as burning fossil fuels.
