Title: Determination of the energy behaviour in municipalities with fewer than 6000 inhabitants in Badajoz (Spain)
Author: Segador Vegas, Cosme; García Sanz-Calcedo, Justo; Encinas Martín, Daniel
Abstract: La mayoría de los municipios de Europa tienen una población de menos de 6000 habitantes y un alto consumo de energía. Para reducir el consumo, es necesario conocer de antemano el comportamiento energético de un municipio. El objetivo de este artículo es analizar la situación energética y medioambiental de los municipios de la provincia de Badajoz (España) y formular indicadores de eficiencia energética y medioambiental. El método se basa en el análisis de 74 auditorías energéticas realizadas entre 2012 y 2014 en los municipios correspondientes, y se estudia el consumo medio de energía final en función de cuatro variables diferentes: superficie del municipio, número de habitantes, coste de la energía y emisiones anuales de CO2. Además, se realizó un análisis estadístico basado en se llevó a cabo una variación. Los resultados obtenidos muestran que el consumo energético anual medio de un municipio de menos de 6000 habitantes es de 300 kWh por habitante y 1 kWh por m2 de superficie. Se observó una gran variabilidad en el costo medio de la energía para cada municipio, entre 0,11 y 0,25 /kWh, con una media de 0,17 /kWh. Además, por métodos estadísticos se determinó que el consumo de energía de un municipio es proporcional a la superficie que ocupa y a su número de habitantes, proponiendo una ecuación que permite determinar el consumo final de energía según ambas variables. Este benchmarking es válido para implementar técnicas de ahorro energético y para priorizar las inversiones en la renovación de las instalaciones. No existen precedentes de estudios de investigación similares con un número tan elevado de municipios.Most of the municipalities in Europe have a population of less than 6000 inhabitants and high energy consumption. In order to reduce consumption, it is necessary to know the energy behaviour of a municipality beforehand. The purpose of this article is to analyse the energy and environmental situation of the municipalities of the province of Badajoz (Spain) and formulates energy efficiency and environmental indicators. The method is based in the analysis of 74 energy audits were carried out between 2012 and 2014 in the corresponding municipalities, and the average final energy consumption was studied in terms of four different variables: area of the municipality, number of inhabitants, cost of energy, and annual CO2 emissions. In addition, a statistical analysis based on variance was carried out. The results obtained show that the average annual energy consumption of a municipality of less than 6000 inhabitants is 300 kWh per inhabitant and 1 kWh per m2 of surface area. A great variability was observed in the average cost of energy for each municipality, between 0.11 and 0.25 /kWh, with an average of 0.17 /kWh. In addition, by statistical methods it was determined that the energy consumption of a municipality is proportional to the surface área that it occupies and its number of inhabitants, proposing an equation that allows determining the final energy consumption according to both variables. This benchmarking is valid to implement energy saving techniques and to prioritize investments in the renovation of the facilities. There are no precedents of similar research studies with such a large number of municipalities.
