“…Research on emissions in houses [34], locomotion [35,36], industry [37], avoided by electric vehicle [38], estimates at the country level [39], or policy guidelines for reducing emissions [40] were carried out. Increasingly, the existence of databases for the evaluation of air quality is being used [41]. In rural areas of developing countries, coal and solid biomass are used as fuels.…”

More than 50% of the world’s population lives in cities. Its buildings consume more than a third of the energy and generate 40% of the emissions. This makes cities in general and their buildings in particular priority points of attention for policymakers and utilities. This paper uses population density as a variable to know its influence on energy consumption and emissions produced in buildings. Furthermore, to show its effect more clearly, the influence of the climate was eliminated. The usual energy consumption in buildings is thermal and electrical. The study was carried out at the city level, both per inhabitant and per household. The area actually occupied by the city was considered. The proposed method was applied to the case of Spanish cities with more than 50,000 inhabitants. The results show that the higher the population density, the higher the energy consumption per inhabitant and household in buildings. The consumption of thermal energy is elastic, while that of electrical energy is inelastic, varying more than 100% between extreme groups. Regarding CO2 emissions, the higher the population density, the higher the emissions. Emissions of electrical origin barely vary by 2% and are greater than those of thermal origin. In addition, the proportion of emissions of electrical origin, with respect to the total, decreases with increasing population density from 74% to 55%. This research aims to help policymakers and utilities to take the appropriate measures that favor the use of renewable energies and reduce CO2 emissions.

“…According to the following study [ 14 ], the publications related to the prediction of air quality using machine learning technologies used more than 26 datasets to supplement air quality data (meteorological, spatial, traffic, social media, etc.). The datasets used in this work are NO 2 data ( μ g/m 3 ), meteorological data and traffic data from January to June 2019 and from January to June 2020, and the location of the monitoring stations.…”

“…Several authors have implemented this model in their work [ 12 , 13 ], but our study will be the first to implement BiConvLSTM in the air quality domain. Regarding the baseline models, LSTM and ConvLSTM were selected (LSTM—based on the Table 1 , which displays publications focusing on NO 2 prediction with implemented methods extracted from the following work [ 14 ]; ConvLSTM—given the fact that many authors have recently used it for air quality prediction). Therefore, the main objective of this work is to predict NO 2 concentration using BiConvLSTM.…”

Nitrogen dioxide is one of the pollutants with the most significant health effects. Advanced information on its concentration in the air can help to monitor and control further consequences more effectively, while also making it easier to apply preventive and mitigating measures. Machine learning technologies with available methods and capabilities, combined with the geospatial dimension, can perform predictive analyses with higher accuracy and, as a result, can serve as a supportive tool for productive management. One of the most advanced machine learning algorithms, Bidirectional convolutional LSTM, is being used in ongoing work to predict the concentration of nitrogen dioxide. The model has been validated to perform more accurate spatiotemporal analysis based on the integration of temporal and geospatial factors. The analysis was carried out according to two scenarios developed on the basis of selected features using data from the city of Madrid for the periods January-June 2019 and January-June 2020. Evaluation of the model’s performance was conducted using the Root Mean Square Error and the Mean Absolute Error which emphasises the superiority of the proposed model over the reference models. In addition, the significance of a feature selection technique providing improved accuracy was underlined. In terms of execution time, due to the complexity of the Bidirectional convolutional LSTM architecture, convergence and generalisation of the data took longer, resulting in the superiority of the reference models.

“…11 Taking into account the above information, the main objective of this work is to predict NO 2 concentration using ConvLSTM and compare it with LSTM, which, looking at the Table 1, can be considered as a benchmark model (Table 1 shows publications focused on NO 2 prediction and implemented methods, these results are extracted from the following paper). 12 The analysis is done for two scenarios: pandemic (January-June 2020) and non-pandemic (January-June 2019), in each of which the following sub-scenarios were de¯ned, based on time intervals (1-h, 12-h, 24-h and 48-h) and features combinations. The Root Mean Square Error (RMSE) metric was applied to evaluate the results provided by each of the models.…”

Traditionally, machine learning technologies with the methods and capabilities available, combined with a geospatial dimension, can perform predictive analyzes of air quality with greater accuracy. However, air pollution is influenced by many external factors, one of which has recently been caused by the restrictions applied to curb the relentless advance of COVID-19. These sudden changes in air quality levels can negatively influence current forecasting models. This work compares air pollution forecasts during a pandemic and non-pandemic period under the same conditions. The ConvLSTM algorithm was applied to predict the concentration of nitrogen dioxide using data from the air quality and meteorological stations in Madrid. The proposed model was applied for two scenarios: pandemic (January–June 2020) and non-pandemic (January–June 2019), each with sub-scenarios based on time granularity (1-h, 12-h, 24-h and 48-h) and combination of features. The Root Mean Square Error was taken as the estimation metric, and the results showed that the proposed method outperformed a reference model, and the feature selection technique significantly improved the overall accuracy.
