Description
Amount of electricity consumed in the buildings of the University of Barcelona in different uses (lighting, operation of electrical and electronic devices, air conditioning, etc.)
| Indicator | 2019 | 2020 | 2021 | 2022 | 2023 | Evolution |
|---|---|---|---|---|---|---|
| Total UB consumption (MWh) | 38.049 | 29.454 | 33.681 | 36.015 | 33.365 |  |
| Consumption per unit area (kWh/m²) | 66,5 | 51,4 | 58,8 | 62,9 | 58,4 | |
Results
Electricity consumption increased by 84% for the UB as a whole between 1995 and 2010, while the increase in the same period was 40% per m2 of built area. This growing trend reflects both the increased use of energy in air conditioning (especially the increase in air conditioning systems in summer) and laboratory machinery or electronic devices, and the increase in built area with the sum of the buildings of at the UB.
From 2010 there has been a change in trend due to the closure of the buildings during holiday periods, the awareness of the university community, greater control of the air conditioning systems and the implementation of energy saving measures, such as the introduction of LED lighting and the gradual renovation of air conditioning installations. Thus, between 2010 and 2019 consumption will fall by 25.4% in total, and by 33.1% per m² of built surface area.
The values for 2020 and 2021 reflect the lower attendance due to the COVID-19 pandemic, and in 2023 a further reduction is observed thanks to the energy saving measures implemented within the framework of the Plan to promote energy saving at the University of Barcelonaincluding the communication campaign «We are responsible».
