DCV, control strategies (BEMS and benchmarking) and building instegrated PV system are the key factors for high performance of the Norwegian Opera Ballet House in Oslo. The summary from the report on “ECO-Culture – Demonstration and dissemination of ECO-concepts for high performing European cultural buildings” (link here) states that this amazing building was performing well and the focus needs to be on continuous work on improvements by operators, one of Swegon Air Academy Case Studies.
Summary of the report is here. After one year of adjustments and improvements all the technologies have shown to work well. One important result is that a good result requires testing and continuous work on improvements by the operators. This process is well documented and it would be useful to continue this process of documentation. For this type of building demand controlled ventilation has shown to be extremely well working and energy efficient. The same technologies will be used further in schools and other cultural building.
The BEMS have a similar impact on the energy consumption as the Demand Controlled Ventilation. It has already shown to be a powerful tool to reduce the energy consumption. The potential is not still fully explored. The combination of interested and skilled operators and leaders together with the BEMS may lead to an even better result than the ECO culture target.
The solar cells are a brilliant example of integrated solar energy in architecture. They are expected to produce slightly above target value. Their relative potential to reduce energy in this building is limited, but the technology is important to develop and demonstrate. It is the only Norwegian demonstration of this kind and scale.
