Energy Demand Visualisation service
The service contains three tools: EPC and Estimated Energy Demand Viewer, Asturias Cadastre data analysis and Asturias Energy Performance Certificates data analysis; and is available both in English and Spanish, as it is developed for the region of Asturias, at the North of Spain.
The service takes advantage of the data of the Asturias Energy Performance Certificates, providing visualisation of them in the building stock, estimation for those that do not have an EPC, as well as data analysed in graphs and tables that can be filtered as desired.
The EPC and Estimated Energy Demand Viewer provides a visualisation of the Asturias building stock of the four main parameters that appear in the EPC(Energy Performance Certificate): heating demand, cooling demand, non-renewable primary energy and CO2 emissions. The visualisation shows the buildings coloured according to the parameter selected and based on the Spanish EPC label values, from A to G, from green to red. The information is provided according to two approaches: Real EPCs approach, which provides the information from the real EPCs (from database of the buildings that have it, buildings that don’t have EPC appear in grey colour), and Estimation based in EPCs knowledge approach, which provides estimations for the buildings that do not have EPC, based on models built considering cadastral data and EPC data (buildings that have EPC are coloured in grey in this approach, as no estimation is done for them). Both approaches can be seen at different scales, from building, to district, municipality and province scale, which contains the information aggregated.
The Asturias Cadastre data analysis and the Asturias Energy Performance Certificates data analysis tools have a similar approach, both showing the data from cadastre or EPCs in a comparative manner, including figures and graphs with the information analysed. Besides, they can be filtered as desired according to certain criteria.
The service includes three tools and they can be changed by selecting the desired one in the three lines at the top bar at the left.
The EPC and Estimated Energy Demand Viewer is opened as a map with a coloured visualisation of the Asturias building stock, according to the four main parameters in the EPC (that can be changed in the options of the bar at the right side), which contains further graph elements to filter in the map and provide more detailed information on what it is being visualised in the screen. The visualisation shows the buildings coloured according to the parameter selected and based on the Spanish EPC label values, from A to G, from green to red. The information is provided according to two approaches: Real EPCs approach, which provides the information from the real EPCs (from database of the buildings that have it), and Estimation based in EPCs knowledge approach, which provides estimations for the buildings that do not have EPC, based on models built considering cadastral data and EPC data.
Both approaches can be seen at different scales, from building, to district, municipality and province scale, showing the information on average values for each approach. If the user clicks on a specific building (or district or municipality, depending on the scale of visualisation), additional information on it (from the real EPC or from the estimation made based on EPCs knowledge, depending on the approach being visualised) appears in the right bar, for example, on building general information (surface, average height, current use, typology, year of construction), on average geometry characteristics (external façades surface per orientation, party walls surface, surface of roof, volume aboveground and compacity index), as well as on the available certificates of the building for the Real EPCs approach, or the information on the estimated EPC values for the second approach.
The Asturias Cadastre data analysis and the Asturias Energy Performance Certificates data analysis tools have a similar approach, both showing the data from cadastre or EPCs in a comparative manner, including figures and graphs with the information analysed (e.g. number of buildings, total surface, construction years, buildings use type, buildings’ status, EPC parameters labels…). They can be filtered as desired according to certain criteria (municipality, construction year, or any of the other information provided).
