Renewal Cooling Plants UZA II

Project objectives

The University of Vienna selected a refurbishment and renewal concept of the cooling system ensuring long-term as well as energy-efficient supply.

Project description

UZA II houses several departments of the University of Vienna, particularly Pharmacy & Nutritional Sciences and Earth Sciences & Meteorology. Due to the complexity of refurbishment, multiple works were affected, such as HVAC, measurement and control technology (MCR), as well as structural and electrical engineering. During construction a minimum cooling load had to be assured for the labs and research areas continued operations.

Project data

Five highly efficient chillers with a total cooling capacity of approx. 3.2 MW with hybrid coolers on the roof will be installed, reserves for future expansion will be additionally created. As this is a very sensitive laboratory and research site, special attention was paid to a very high functional and failure safety during the implementation of the concept. Therefore, an interconnection line between the refrigeration plants will be built to ensure a corresponding redundancy.

Services

• Temporary cooling system to maintain partial operation
• Renewal of chillers, cooling towers, MCR and interconnecting pipeline
• Electrical supply, structural adaptations and fire protection measures
• Project control & construction supervision (HVAC, electrical engineering & structural engineering)
