TA takes control of hydronic systems in Austrian HQ building
The 20 000 m2 head office of Energie AG in Austria makes extensive use of balancing valves from TA Hydronics to control the building’s energy use in line with its passive energy concept. TA supplied 540 STAP and STAD balancing valves to meet the 800 kW heating requirement, 400 kW for cooled ceilings and a further 400 kW for cooling supply air. There are two differential-pressure controllers in every room, one for heating and one for cooling.
TA Hydronics worked closely with the consultant and technician at Energie AG to create a system that would meet the energy-efficiency requirements expected from the building. Using a variable-flow solution comprising a 4-pipe system, it was possible to achieve a far superior level of control over the hydronics and reduce the number of circulating pumps.
Energy sources include the River Danube for heating and cooling and 700 m2 of solar PV panels attached to the facade.
