Description:
Planning services are required for the construction of a heat network in the Hafner area of Konstanz, focusing on plant technology and building structures to support air-water heat pumps.

Planning services for Lot 1: Plant technology and building transfer stations, Lot 2: Building and structural planning


LOT-0001
Plant Technology.
As part of the municipal heat planning of the city of Konstanz and the subsequent strategic heat network planning of the municipal utility of Konstanz, areas in Konstanz have been identified that are primarily suitable for the establishment of heat networks. One of the results of the previous planning is the project area considered here, "Hafner", which is located in the northwest of Konstanz. It is a new development area. The project area, which has a high heat demand density while requiring a low temperature level, is suitable for being supplied by air-water heat pumps. Lot 1 includes the planning of the air heat pump system technology (installed outside) with natural refrigerant, hydraulics, pressure maintenance heat storage, etc. from outdoor air to building interface towards the heat network. Implementation of the entire electrical planning (cross-lot). Coordination of the MSR (measurement and control technology) planning, implementation of the MSR planning for the plant technology lot. Planning of the building technology (including electrical engineering) of the energy center. Additionally, approximately 220 building connection stations (HAST) are to be planned, which can be divided into different clusters.
