Efficiency optimization and energy management of the building, thanks to the BIM methodology

The Torrelavega bus station exhibited various energy failures, due to its structural conditions and the construction characteristics of its equipment. Thus, the first energy evaluation, using the Sudoe Stop CO2 self-assessment tool, resulted in a low energy rating of the building, with only 2 out of 5 stars, energy failures to be resolved.

As a case study under the Sudoe Stop CO2 project, the BIM methodology was used to mitigate the problems detected. A digital model of the building in 3D was therefore built and shared with experts in thermal and energy studies who, by applying a software specific to the model, proposed alternatives to reduce the energy costs of the bus station. The solutions included replacing the lighting system, as well as passive actions such as using natural light or improving air circulation. The process was completed with the refurbishment of the lighting system, which reduced consumption by up to 50% and achieved a 3-star ranking in the network of Sudoe Stop CO2 sustainable public transport stations.

The digital mock-up has been enriched with new elements so that it can be used as a tool for building maintenance and management, as well as to collect and recount data from the monitoring systems installed in the bus station.
