In this project the Escaldes-Engordany energy system is characterized in high technological detail, geolocating the main consumers of energy in parallel to future potential generating installations (such as, for example, those of photovoltaic solar energy). The analysis is performed through a UBEM (Urban Building Energy Model), a type of bottom-up model designed specifically to understand the spatiotemporal patterns of energy use in urban areas [1]. This model allows to analyze individually the saving’s potential in the different buildings through energy efficiency actions, as well as study the challenges and potentials of a change of the energy model based in the distributed generation, tools of demand management and heat networks.


This project has devoted great efforts to the model’s characterization step, providing a new methodology for building representative archetypes’ development through the use of electricity consumption metered data [2], [3]. In parallel, and with the aim of characterizing the systems present in buildings as well as the user ´s behavior, an in-situ survey was conducted on 294 buildings [4].

The computer model implemented is represented on a 3D model of Andorra. The display on the model allows to encourage interaction with the main people in charge of the decision-making in energy matters. On the other hand, it serves as an educational and awareness-raising tool for the general public.

The project “EnergiAnd, promoting the energy transition” [5] has been funded by the Government of Andorra in the framework of the Research or Transfer Grant that can be applied in Andorra, in accordance with the principles promoted by the ActuaTech Foundation (APTA0014-AND / 2017) and is carried out in collaboration with the Universitat Politècnica de Catalunya.
