Description
Auto-translated from GermanPlot No. 3396 is located in St. Margrethen SG, in close proximity to the A1 motorway and the border with Austria. The Federal Office for Buildings and Logistics (BBL) plans to build a new Intervention Center (IVZ) with several building sections on the site. The construction project includes a main building and several ancillary buildings with associated technical facilities and infrastructure. 242 Heat and Cold Generation Space heating, air heater, and hot water heating are supplied by a brine/water heat pump (refrigerant propane; heating output 150kW) with a geothermal probe field. The heat pump manages a buffer storage. The geothermal probe field is used for free cooling in the summer, which helps to balance the energy in the ground. The brine/water heat pump is reversible, so that it could be used as a chiller if the demand for the cooling system increases. Distribution and connection to the individual buildings are via a manifold, with one circuit per building for space heating and one for the respective air heaters of the ventilation systems. The circuits can be used for cooling with a changeover system. All the aforementioned components will be installed in the heating/cooling center on the 2nd floor of Building C. Geothermal Probe Field The geothermal probe field consists of 16 geothermal probes, each 250m deep. The geothermal probes are located under Building C (garage section) and are combined in a basement room at a collector manifold. The brine circuit (water) supplies the cooling circuits for free cooling operation via a plate heat exchanger. 246 Heat/Cold Distribution For space heating, an underfloor heating system is used in the interior rooms, fan coils in the sill for the exterior rooms, and floor convectors for the cafeteria. In the light wells on the 2nd floor, heat loss at the windows is compensated by floor convectors. The desired room temperature can be individually set (limited) per room via a room sensor from the control system. In summer, the waste heat in the rooms can be dissipated using the changeover system via the underfloor heating, fan coils, and floor convectors (fan-assisted). Pipes and fittings, vertical risers are insulated with halogen-free synthetic rubber.
