Energy consumption
Evolution of energy consumption
The UAB has decreased its energy consumption by 13.75% in the last year and has consumed 39.20% less energy than in 2010. For electricity, the reduction was 5.73% (1,711,956 kWh) while for gas it was 24.89% (5,355,463 kWh) compared to the previous year in both cases.
This decrease was mainly due to the actions taken to improve the energy efficiency of the facilities as well as the optimisation of the management systems, the deployment of renewable energies and a winter with above-average temperatures.
The emissions associated with this consumption (emissions attributable only to gas because the electricity consumed at the UAB comes from renewable energy sources certified with a guarantee of origin) have decreased by 20% compared to last year.
Economic expenditure has increased by 91.60% compared to 2022 and by 21.35% compared to 2010.
The production of renewable energy in 2023 was 1,804,618.79 kWh which represents 4% of the total energy consumption (electricity and gas) of the UAB.

Summary of total UAB consumption for the year 2023
Summary of total UAB consumption for the year 2023.
During 2023 the production of renewable energy at the UAB amounted to 1,804,618.79 kWh, which represents 4.07% of the total energy consumption (electricity and gas) of the UAB.
The technology that provides the greatest renewable production is the biomass boiler, installed in the Physical Activity Service building, with a production of 58% of the total. In second place is photovoltaic solar energy, which is increasing its production as the photovoltaic solar plants implemented in recent years are brought into service. Specifically, in 2023 we have had in operation those of the School of Engineering, the Faculty of Veterinary Medicine as well as Computer Services, the Library of Humanities and the C3 odd spine of Sciences.
The production of renewable energy at the UAB has been growing year after year, with a significant leap in 2016 with the commissioning of the biomass boiler, in 2019 with the renewable energy production technologies of the ICTA-ICP building and later with the commissioning of the solar photovoltaic plants.
The decrease in renewable energy production in 2022 is due to a reduction in the energy demand of the SAF building, and therefore less use of the biomass boiler. The higher than average temperatures in the winter period have been the main cause of this reduction.
