HI distribution centre for the Anergy grid

As one of five distribution centres, the HI distribution centre heats and cools the HI buildings and ensures that waste heat from individual buildings is redistributed directly to other buildings. If this waste heat is not required within one group of buildings, it will be transferred to other groups via a looped pipe system; if it is also not required there, it will be stored in geothermal probes, available for future use. The cooled area of ground is used as a geocooling system in summer and then heated again using waste heat from the buildings. This seasonal management creates maximum system efficiency.

The development of the energy supply and the Anergy grid is leading the way for sustainable operation of the buildings and research infrastructure on the Hönggerberg campus.

The concept will have a positive impact on both fossil fuel use and costs, and plays an important part in fulfilling the energy efficiency goal required by the “Confederation: exemplary in energy” initiative (VBE) to realise the Federal Council’s Energy Strategy 2050.

BIM

ETH Zurich is working with the optimised planning method BIM (building information modelling) for the HI distribution centre. The data and information created during the planning process are digitally recorded, combined and cross-referenced. By combining the 3D specialist models, it was possible to give the building owner or users visualised access to the project even in its early stages, as shown in the following video about the HI distribution centre.
