The Hydronic Challenge
The University Park, Nonntal, a renowned institute for encouraging young talented musicians, is located in one of Austria's oldest cities and the birthplace of music composer, Wolfgang Mozart, Salzburg. Because of the proposed use of this new 29,800m2 university building, it was vital to meet the right indoor temperature conditions, notwithstanding significant changes in outside temperatures.
Due to the complexity of the system, design support was required to ensure the correct flow compatibility between production and distribution, a key issue in the correct functioning of heating and cooling systems. Buildings that do not meet this requirement, experience occupant complaints and often higher energy costs due to an inability to provide the right temperature especially at peak periods of use. Diagnosing the problem of flow incompatibility, often leads to expensive investments into other equipment. These investments will still not solve the problem and will lead to even more energy being used, but without being able to distribute it effectively (so avoiding this is crucial for energy savings).
The project also required correct system pressurisation in order to prevent corrosion and prolong equipment lifetime.
