CTA ensures cool heads in the Northern Federal Parliament building
In the Federal Parliament building in Bern, custom CTA chillers also ensure pleasant room temperatures on hot days. The modern cooling solutions, which were implemented as part of comprehensive redevelopment works, integrate perfectly into the historic building and prove their worth through their operational efficiency and low energy consumption.
In brief
Renovation of building technology in the listed building
Eastern Federal Parliament building: cooling for the IT and data centre, as well as air conditioning with two separate, mutually independent cold water networks
Northern Federal Parliament building: a chiller using the hydrofluoroolefin (HFO) refrigerant
Heritage conservation requires experience
The redevelopment of listed buildings and the renovation of building technology place high demands on all the companies involved. Cooling technology, which is usually entirely absent from historic buildings and now has to be installed separately, is therefore required. For effective cooling solutions in historic buildings, customised systems are therefore needed—as well as extensive experience of challenging environments.
Eastern Federal Parliament building
Cooling for the IT and data centre, as well as air conditioning with two separate, mutually independent cold water networks:Cooling the technical and server rooms using two chillers, each with a 143 kW cooling capacity and a 6.36 energy efficiency rating (EER)
Responsible for air conditioning the offices, the other chiller is equipped with four scroll compressors and a total cooling capacity of 130 kW (EER 4.25).
