Cutting-edge building automation for maximum energy efficiency and security

The automation specialists of GFR – Gesellschaft für Regelungstechnik und Energieeinsparung mbH – meet the requirements of the complex and technically sophisticated reconstruction project of the Olympic Hall Munich. The building services are being modernised and BACnet serves as a sustainable basis for those endeavours.

GFR faces several challenges during the reconstruction of Munich’s well-known event location: ensuring smooth operation of events while implementing comprehensive building automation systems. This includes the integration of all trades as it relates to technical building services, like heating, ventilation and air-conditioning. The fire control system complies with the latest guidelines. GFR provides “invisible intelligence“ by means of comprehensive solutions and highly efficient control strategies.


Extensive reconstruction of refrigeration plant

In accordance with the modernisation of the Olympic Hall Munich, GFR was asked to replace the existing refrigeration plant control.
In addition to the conventional refrigeration control, GFR created two control systems for the refrigeration plant, a set of controllers for the security technology of the machine room and a low-voltage main distribution.
The refrigeration plant cools down a medium to temperatures of up to -20°C. The medium is stored in a 40-m³ glycol container and lifted to the next level for refrigeration supply by means of two heat exchangers.

A connection for a mobile ice track has been considered as an optional extension. By doing so, an energy-efficiently generated cooling medium can be provided for the guest organisers of figure skating shows and ice-hockey tournaments. Respective arrangements and preliminary setups have already been considered. Components of the existing plant were built in the course of the preparations for the Olympic Summer Games in 1972. This is remarkable, especially since the majority of the components could be reactivated with no errors, even after a three-year downtime.
