Jernhusen – Gothenburg Central Station
This station is the traffic hub for entire western Sweden. The Central station, Centralhuset and Nils Ericsson terminal form Gothenburg Travel Centre which more than 90,000 passengers pass through every day. The station was constructed in the middle of the 19th century and has been reconstructed successively since then.
During 2009 a new control and regulation system was installed in the property as a part of a technical modernisation project. In 2014 Kabona was assigned to install an Ecopilot which through over-modulation of the five year old control system would continuously optimise the property’s energy consumption.

Now the Ecopilot and the existing control system work together. The Ecopilot continuously estimates the property’s optimal energy operating mode by taking into account internal user loads, external weather impact and thermal storage capacity. The result was a pleasant indoor environment and low energy consumption.
Gothenburg Central Station now has an F-classification in accordance with the European standard for energy efficient buildings. This corresponds to 180–235 per cent of the new construction requirement for premises. Without an Ecopilot installation, Gothenburg Central Station would have a G-classification.
