Measurement, Verification, Optimization

How well do non-residential buildings, which are often labelled  ‘innovative’, ‘‘green’ or ‘intelligent’ in the ambitious early design phase really perform in everyday use? Do they perform as intended? What does really work? Research projects have shown: Many buildings fall well below their energy efficiency targets or do not meet user expectations. And often building owners and even the architects and engineers don’t even know about their buildings performance: Do they learn from their projects?

Measurement and verification have become an integrated part of commissioning for energy efficient buildings enabling engineers to significantly enhance building operations. Within the EnBop section of EnOB research and development projects are carried out developing new methodologies and tools to analyze and optimize building operation and applying them to innovative buildings and building services. The projects reach from commissioning guidelines for innovative systems to new software for automated analysis of buildings operations.

The model-based ModQS quality assurance has been tested on seven example model projects, including the building belonging to the State Agency for Nature, Environment and Consumer Protection (LANUV) in Düsseldorf

Model-based quality assurance for multi-boiler regulation

As part of the ModQS research project, a process was developed for the measurement-based commissioning and operational monitoring of building services systems. The focus is on existing buildings and heating systems in non-residential buildings. The process is intended to be able to work with relatively little information and measurement values, and should therefore be suitable for real building operations. It has now been tested on seven pilot buildings, including the building belonging to the State Agency for Nature, Environment and Consumer Protection (LANUV) in Düsseldorf.

The Kraft Foods building in Munich is one of six buildings to be evaluated and optimised as part of the ModBen research project. The laboratory building with an office wing was built in 1986.

Functional Quality Control for Laboratory and Office Building

This laboratory and office building is used to develop new food products. The building has a very high energy consumption, as its technical equipment is complex and power-intensive due to its use. The laboratory building was subjected to continuous functional quality control as part of the ModBen research project. That was not easy, as, while there are automation stations, there is no superordinate building control system.

Seasonal heat management for new head office building

With its fully glazed facade, the striking-looking office block expands the head offices for Gelsenwasser AG. The old and new buildings stand side by side and are linked together with glazed bridges. The two buildings are also coupled together in energy terms. The new building commenced operation back in 2004. However, because the energy-related planning objectives were not achieved during actual operation, the building has been monitored and optimised since 2007. The resulting scientific evaluation shows that the careful commissioning and operational management of complex buildings is not just very important but also very demanding.

Seasonal heat management at the EnergieForum Berlin

The EnergieForum Berlin is a building complex whose ambitious energy concept relies on energy piles for providing seasonal heat and cooling storage within the building’s foundations. The monitoring of the building started soon after it was inaugurated. A decisive problem was the continual increase in the ground temperature. However, by means of many different measures that did not require capital investment, considerable improvements have been made to the building’s performance and the heat and cooling storage in the foundation area has been successfully balanced out.

Volkswagenbibliothek in Berlin

The building for the Volkswagenbibliothek in Berlin was evaluated shortly after it opened in terms of its energy efficiency and levels of comfort. As part of an energy-oriented optimisation of the operation, the primary energy consumption was lowered within one year by 19 per cent. At the same time, the user comfort has improved tangibly.

Head office of Siedlungswerk

The head office building for Siedlungswerk gGmbH, which is situated in the centre of Stuttgart, was evaluated with a view to optimising its operation. The aim was to lower the energy consumption and at the same time make it more comfortable to use. The optimisation focussed on the heating and ventilation systems.
