In order to ensure the transferability of the COLEOPTER approach, a transfer case study will be made in Andorra. The selected building, located in the heart of Escaldes-Engordany, is the Prat Gran Pavilion.

The building to be renovated is located in the centre of Escaldes-Engordany, the second most populated town in the Principality of Andorra.

The Prat Gran pavilion is a communal building built at the end of the 1990s. It has a built surface area of 37580 m2 located on a plot of 4390 m2.
The constructed space consists of 5 floors, the useful surface areas of which are detailed below:
– Floor -2: 12452 m2
– Floor -1: 12453 m2
– Semi-basement floor: 4208
– Ground floor: 4337m2
– First floor: 4130 m2

Although the building includes different uses such pakings, a post office, a health care centre and a senior centre, the main use is as a sports centre. Among the many users of the sports centre, the most relevant are sports clubs (basketball, football, judo, tennis, etc.), schools and the users of the senior centre.

The conditions of the building are particularly beneficial for carrying out the territorial dialogue, as the building has an important social use. The main objective of the dialogue is to identify measures to improve the comfort of the building taking into account energy and water efficiency.
The implemented BIM model will enrich the dialogue by allowing to quantify the energy and water impact of the different identified measures.


The collaborative platform, developed by CETENMA, allows local interest groups and the general public to view the virtual 3D model of the pilot building, learn about its properties and make suggestions and modifications to it. The objective is that the stakeholders participating in the Territorial Dialogue process became an active part of the building renovation project. Their contributions will help to achieve the desired objective for the future of the building.

Through the BIM model, the structural and energy simulations of the proposed solutions will be carried out by experts. The result are shown in what we call senarios, that can be visualized, in order to facilitate decision-making in the rehabilitation of the building.

ACCESS the building BIM model in an intuitive way and LEAVE YOUR COMMENTS

To analyze and get to know the building in depth, you can navigate through the model by taking a tour of the different spaces. You can use the full screen option for better viewing.

Select the element of the model, on which you want to suggest a change (for example a window, equipment, room, among others), leave your name and leave your comment.
