Case Study buildings in Vitoria-Gasteiz

European projects SmartEnCity and BIM Speed join forces in Coronación demo district

25 Nov 2019

Coronación Demo District in Vitoria Gasteiz is harnessing European resources to become more sustainable and to enhance citizens’ life quality. Two European projects SmartEnCity (GA 691883) and BIM Speed (GA 820553) are sharing two buildings from the demo district as case studies in two complementary approaches that may serve to fulfil both projects’ main objectives while providing the tenants with a higher comfort with cutting edge technologies applied in renovation.

The two buildings, built in 1958, are located in the Lighthouse City of Vitoria-Gasteiz. The first demonstration site, ALDABE 26, is a four storeys residential U-shaped building comprising eight flats, with double brick external walls and with an air chamber in between. The second demonstration site, MANUEL DIAZ DE ARCAYA 5, is a 5 storeys residential H-shaped building comprising 12 flats. Some external brick walls are cavity walls, while other walls are just bearing walls composed of a single layer of bricks without any air chambers. Both buildings are not insulated and have a poor energy performance with condensation and humidity problems.

On one side, these two buildings are part of Lighthouse demo area within SmartEnCity project, where during the next months, renovation activities will implement insulation of the building envelope focusing on external enclosure, façades and roof, plus connecting the dwellings to a new district heating system based on biomass energy. On the other hand, during BIM-SPEED project, new tools and solutions such as as-built data acquisition, designing, energy simulation and construction works will be implemented to enhance retrofitting works and to make them more efficient. SmartEnCity looks for better living conditions and less CO2 in the cities, while BIM-SPEED aims to improve the performance of these two buildings by developing and applying a combination of methodologies and tools with one central information source at its core: the Building Information Model (BIM), a digital representation of a building. This model will be the catalyst for a smarter, more efficient and faster method of deep renovation for the residential building sector across the European Union.

This example proves again “Collaboration is a winning bet!”
