The socio-cultural quality of the research & development building on the octapharma campus in 1100 Vienna was investigated as part of a sustainability study. Following this investigation a deeper analysis was carried out with the objective of making proposals for improvement.

The investigation was preceded by an initial analysis of the technical infrastructure. This comprised a recording of the general functions, performance levels and energetic behavior. Potential for increasing efficiency was already indicated at this point

  • A thermographic investigation of the building envelope and building services enabled the thermal behavior of the building to be recorded.
  • A visit to the plant and office areas offered clear information about the current functioning and performance of the energy supply Systems.

In a detailed analysis drawn up on the basis of this initial appraisal further potential improvements were found. A concept for optimizing the use of energy was drawn up on the basis of the visit to the plant areas together with the existing installation diagrams. The following measures were planned as part of this concept:

  • Incorporation of a hydraulic switch into the primary cold production circuit in order to improve the performance and life expectancy of the existing cooing plant
  • Modification of the connection of the heat emission circuit to the main distributor in order to avoid mutual interference between the two forms of operation.
  • The requirements for all currently installed pumps was questioned and continuously improved during the operation of the building
  • Building measures were developed in order to minimize energy loss from the plant room and, hence, increase the efficiency of the system.

In order to be able to contrast the current energy demand with a reference value the building was also modeled in a dynamic thermal simulation. The results can thus be compared with the performance requirements and energy demand of actual building operations.
