Population residing in existing buildings that, due to exclusively economic reasons, are in a situation of vulnerability. The situation of economic vulnerability that affects a certain part of the population can lead to a decrease in their quality of life, associated with a reduction in the budget for their basic needs, and an increase in the risk of social segregation due to wage inequality. Knowledge and analysis of this situation can help to mitigate these risks. Data include: population with average income per consumption unit below the at-risk-of-poverty threshold (stipulated at €10,088 according to the latest available data from 2022).
Existing buildings designed and constructed with materials and construction systems that minimise energy demand and/or have efficient installation systems whose technology allows the reduction of energy consumption resulting from their demand. The definition of these buildings allows the identification of the remaining percentage of buildings that require prioritisation in terms of the refurbishment of the entire building stock, in accordance with the new Energy Performance of Buildings Directive (EU Directive 2024/1275). The data includes: buildings with indoor air conditioning energy consumption of less than 150 kWh/m2year (stipulated according to the threshold defined for the average value of Catalan buildings).
Existing risk for the resident population to be susceptible to negative impacts on their health during periods of high temperatures due to the conditions of the environment and the buildings in which they live. The identification of vulnerable areas allows the identification of priority areas for building and urban rehabilitation, in conjunction or in line with bio-construction strategies. The data include: buildings with a high risk of vulnerability to heat waves for the resident population (stipulated as greater than or equal to 4 on the scale for the indicator Empitjorament del confort climàtic: accentuació del fenomen d'illa de calor defined by the Oficina Catalana del Canviàtic Climàtic).
Existing buildings that have an Energy Performance Certificate (EPC) for the whole building, in the case of single-family and multi-family dwellings, or for some or some of the dwellings that make up the building, in the case of multi-family dwellings, regardless of their rating, and according to the register of the Catalan Energy Institute (ICAEN). The identification of buildings with EPCs makes it possible to analyse the situation of the building stock in terms of energy efficiency. The data include: buildings with at least one registered EPC (stipulated as a minimum number that reflects the real data of a building or the estimation of its energy category when composed of a certain number of similar dwellings).
Existing buildings that produce renewable electricity for their own consumption, through the installation of photovoltaic panels, processed or with their procedures updated in accordance with Royal Decree 15/2018 and Royal Decree 244/2019, and that are registered in the Registre d'Autoconsum de Catalunya (RAC). The identification of these buildings makes it possible to promote community energy management initiatives, such as energy communities, and to plan the ecological transition, optimising the electricity infrastructure. The data includes: buildings with a RAC registration number that have an installed power of more than 0kW, regardless of the type of building, number of consumption and generation points, and amount of surplus generated.
Existing buildings that, due to their characteristics, and considering a fictitious system with a maximum number of photovoltaic panels of 450 peak power, oriented in a relatively optimal position (south and coplanar), and positioned considering the restrictions of passage and the estimation of shadows, present a great potential for renewable electricity generation. The identification of these buildings and their location allows the assessment of opportunities for energy transition in terms of self-consumption and energy management and optimisation. The data includes: buildings that, after inclusion and simulation of the fictitious system, have a generation above the threshold of 50,000 kWh/year
Buildings with resident population that, due to socio-economic aspects, habitability conditions of the buildings in which they reside and characteristics of the urban space in which they are located, present a risk of social exclusion and housing vulnerability. The identification of these areas makes it possible to assess risks of population segregation, lack of access to housing and deficient urban services. The data include: buildings with an overcrowding threshold of more than 80% of the percentage of occupation considered healthy per dwelling (stipulated according to the Catalan Housing Code and the Habitability Certificate), buildings located less than 15 minutes on foot or by bicycle from the threshold of 6 basic services, and buildings located less than 15 minutes on foot or by bicycle from the threshold of 6 basic services (stipulated by the Catalan Housing Code and the Habitability Certificate).
Residential buildings that, in each climate zone and typology (single-family or multi-family), belong to the 43 % of the worst energy efficient stock, identified as having the highest levels of final energy consumption. These buildings are proposed as a priority in the renovation programmes to be defined by Spain when transposing the EPBD 2024, as their modernisation is essential to achieve the 16 % reduction in average primary energy consumption required by 2030 and to ensure that at least 55% of these savings come from the renovation of the least efficient buildings, as established by the European Directive.
