Renovation of Competence Center Dornbirn (office building)
Dornbirn, Province of Vorarlberg, Austria
The Competence Center Dornbirn accommodates various companies from the fields of construction, environment and energy as well as complementary business services and is affiliated to the University Campus Dornbirn. The modernisation of the building was intended to consolidate and promote its use as an innovation centre in the long term. The shell, which was already well conditioned when the building was erected, and the building services will be adapted to the current state of the art with a focus on economic benefits. The following measures were implemented:
- Deconstruction of steel and reinforced concrete elements to reduce thermal bridges in the attic and façade area.
- Replacement of the old mullion-transom facade on ground floor and 1st floor
- Use of aluminium windows with 3-fold glazing
- new shading by electrically driven, controlled external blinds
- Replacement of the existing ventilation system by a system with higher efficiency
Benefits
The measures implemented have led to a significant improvement in comfort. The sound absorption through the new windows helps to significantly reduce the noise level in the offices. The technical building measures lead to a considerably improved room climate, which is noticeably and pleasantly noticed by the users.
Mechanical ventilation was a major topic in the target definition, whether centralised or decentralised. The negative experience of a ventilation system in a school that had just been implemented at that time had a strong influence on this discussion.
