A Replicable but Completely Adjustable Tool. The Customisation Made to the City of Valence (Spain)
ACCENT tool has been designed to be easily replicable. That means that a harmonized data model and a common calculation method have been defined for all the cities that decide to be part of ACCENT. However, the tool is also user-adjustable and adaptable to meet the data available on each territory. ACCENT tool provides output results at different scales depending on the granularity of data each territory or city is willing to provide. In addition, it is also susceptible to be improved by means of database updates, corrections made by the specific users or other improvement’ measures, such as the intelligent feeding of data through the use of smart meters.
To initialize calculations, it is required to provide the tool with the input data necessary to make ACCENT tool engine works. For each city, different levels of spatial data are needed: building, sub-district and district data. In addition, other input parameters such as CO2 emission factors or primary energy factors are considered at national scale. The collection of input data (parameters, scale and sources) carried out by the team in order to launch the calculation for the City of Valencia (Spain) is shown in Table 3.
