The municipality of Wermsdorf intends to construct a two-story primary school building with the zero-energy standard. The building will be heated by an efficient geothermal heat pump with ground loops. In the building itself, the existing storage masses (concrete core activation) will be used to increase the efficiency of the low-temperature heating system. To support the planners of IPROconsult, EA Systems Dresden GmbH carried out model-based evaluations of the energy demand, system and control concept.

Thermal and System Simulation

  • Modelling of system control and technology li>
  • Determination of the heat and electrical energy demand by dynamic simulation of the usage and building behaviour
  • Identification of the room and zone-wise thermal and electrical loads (load curves)
  • Documentation according to EnEV 2016 for non-residential buildings (energy demand certificate) and EEWärmeG

Regulation and Control Optimization

  • Specifications for individual room ventilation control and room-by-room configuration of the heating and ventilation technology
  • Model-based investigation of system variants
  • Model-based investigation of control systems
  • Simulation of a preferred variant and identification of the optimum control system as well as investment and operating costs
