Building product management

Choosing building products with care improves the quality of indoor air, scores points in building evaluations and reduces the use of pollutants. There are lots of details to considered – a structured process makes everyone's work easier. Through the building product management system, we provide assistance in the selection of healthy and environmentally compatible building materials from the planning phase onwards.

  • Agreement on the applicable criteria
  • Establishing the criteria used in tendering and contracting
  • Initial discussion with planners and builders
  • Site inductions with contractors
  • Approvals and optimisations for building products with the individual trades
  • Site visits for random checks
  • Final indoor air measuring
  • Written documentation

We offer building product management for all building certificates: klimaaktiv, IBO ÖKOPASS, ÖGNB, ÖGNI, BREEAM, LEED. As well as for public buildings, for new constructions and renovations alike.

Architectural Description:

In terms of sustainability, the compactness of the structure in terms of energy efficiency was taken into account in addition to the wooden construction. The appearance is characterized by the wooden construction, the facade surfaces remain untreated. The grid of the facade is continued in the interior of the entrance level and the library in the ceiling construction. The supporting structure becomes a design element, and floor-to-ceiling glazing creates a dialogue between the interior and the surroundings. By opening individual elements, the raised plaza can also be used as a terrace, marketplace or meeting place for students, depending on the season. Apart from the base, which is partly in contact with the ground, and the staircase (fire protection), the entire building is constructed from prefabricated wooden elements.

Functional Aspects

The use of the building is structured in such a way that rooms with high occupancy rates are located in the base zone, while institute and pool rooms are located on the upper floors. The solidly built base zone accommodates 8 of the 10 seminar rooms, which are lit from the north and south sides. This zone is accessed via the entrance level above, where the two large seminar rooms are also positioned. These can be connected together and, together with the foyer (store and bakery), provide the optimal infrastructure for larger events. The library can be reached directly from the entrance level via its own staircase. Like the seminar rooms below, the learning spaces are oriented to the northeast, towards the green space with valuable trees; the EDP user rooms are located on the south side. The pool rooms are located on level 2, and the Institute of Transportation on level 3. Both levels have a meeting room and a kitchenette.

Economic, Ecological Aspects

In addition to all the ecological advantages of a timber construction, the short erection time is particularly worth mentioning. Also for spans for the prefabricated element sizes, a resource-saving, optimal dimensioning is strived for.

Building Envelope:

The thermal building envelope is formed by optimally thermally insulated opaque components and 3-pane glazed windows. An external, movable shading system prevents excessive solar gain in the summer months. The wooden construction elements are visible from the outside and thermally separated from the heated area. Correspondingly high air tightness as well as connections with low thermal bridges in connection with the thermal component qualities guarantee the attainment of the lowest energy house standard.

Heating:

The heat in the rooms is provided by underfloor heating. The heat required for this is drawn from the district heating network.

Facilitation cooling:

In order to create a comfortable indoor climate in summer without using active cooling or air conditioning at the same time, a low-tech direct cooling system is planned. For this purpose, the floor slab is thermally separated from the building and covered with absorber pipes. Optionally, ground probes are also installed and the cooling is collected in a buffer tank via pipes laid in this way. In summer, cold water is fed from this buffer tank through the floor, thus counteracting overheating of the rooms.

Ventilation:

The ventilation of the seminar rooms takes place via a ventilation system in the 2nd basement. The outside air is drawn in from the north side via a tower. The air is then fed through a heat and moisture recovery system and then into the seminar rooms as supply air. The exhaust air comes directly from the seminar rooms via the duct network back to the ventilation unit and is blown out as exhaust air on the facade of the 1st basement floor. The library with 100 reading places and the interior meeting rooms on the upper floors 2 and 3 are also supplied with supply and exhaust air. The associated ventilation system with heat and moisture recovery is located on the roof as an outdoor unit. All other common rooms have the possibility to be ventilated via windows. The indoor sanitary groups are ventilated via a separate exhaust air system.

Use of local renewable sources:

For local electricity generation, the available roof areas are equipped with a solar power system mainly to cover self-consumption.
