Siemens Zug

Baumann provided fundamental and enhanced commissioning and monitoring-based commissioning services to support the project’s LEED Gold certification.

Siemens renovated an office building in Zug, Switzerland, which included the replacement of the MEP systems. The building achieved a LEED BD&C Gold certification.

Baumann provided fundamental and enhanced commissioning and optimized the operation during the first year of operation with monitoring-based commissioning (MBCx).

Heating and cooling, as well as hot water and process heat for the labs, are provided by water-water heat pumps. Water from the lake near Zug, 0.7 miles away, serves as the heat source and sink for the geo-exchange system.

The main features that contribute to the energy efficiency of the building:

  • Heat Pump system utilizing lake water
  • Passive cooling with lake water
  • Dedicated outdoor air systems with heat recovery and high-efficiency fans
  • High-quality facade
  • Motion and daylight sensors

Some of the findings identified by the trend data analysis for MBCx are:

  • Supply air temperatures higher than designed (>22 °C in summer). Over 50% of the data points are outside of the tolerance (highlighted area in the graph below)
  • Heating in the summer with an ambient temperature of more than 26 °C
  • AHU not operating according to the designed schedule

The resolution of those items lowered energy consumption and increased thermal comfort.
