Nearly Zero Energy Office Building
Integral planning, control optimization & pre-built Commissioning
The owner’s focus was to drastically shorten the commissioning phase and to really obtain a high performance NZEB-building as designed, meaning an outstanding energy performance and high levels of comfort.
Therefore it was important that all relevant parties work together from the very beginning and keep collaborating through the construction until commissioning and operation.
The construction project was framed with a research project to act as a test bench for energy-efficient automation and control of buildings.
Out teams’ focus were the development and optimization of control strategies and data analysis during the first year of operation.
The great results and the client`s satisfaction at the end of the project made this a real highlight-project for us!
Realisation 2017, 49.000 m² incl.5000m² commercial space (gastro, supermarket, shops)
Architect: Schenker Salvi Weber & feld72
Control strategy optimization and virtual testing on real hardware
Project brief
Goals
Significant time reduction of the commissioning phase
Assurance that the nearly zero energy building really performs as planned
Development and optimization of control strategies with focus on part load conditions for all air conditioning systems, concrete core activation and especially free cooling
Solution
Scientific planning support from early planning stage until commissioning involving representatives of ALL project partners (Owner, facility management, HVAC planner, building physics, control engineers, etc.)
Application of the novel Hardware in the Loop (HIL) approach as part of quality assurance measures allowing the control strategies to be tested on the real hardware prior to installation
Development and optimization of control strategies for all systems using dynamic thermal simulations. The results were lateron used by the control engineers and facility management
Our Role
As part of AIT:
Reviewing the highly complex dynamic thermal system simulations
Advising the owner in the first year of operation for continuous improvement and quality assurance
Conducting monitoring data analysis and presenting solutions for increased energy efficiency and comfort to the owner
