The building, situated where national road 40 connects towards E6 in Gothenburg, was constructed in the 1960s as an industrial property. It was totally renovated in 2007 and now houses many different businesses such as a hotel, restaurant, gym, grocery store and offices.
The property had modern installations and control systems. However, there were still deficiencies in the system collaboration which created problems with the indoor climate. Ecopilot® was installed and its only assignment is to over-modulate ventilation, heating and cooling systems so that they are adjusted to each other. It also takes into account the property’s thermal storage capacity as well as internal and external loads.

After the renovation in 2007, the property was classified as a Green Building. Simply through the Ecopilot® installation, district heating consumption was reduced by 20 per cent and electricity consumption by 15 per cent. Now the building takes into account internal user loads, external weather impact and thermal storage capacity. The result has also contributed to a more pleasant indoor climate.
Mektagonen now has an E-classification in accordance with the European standard for energy efficient buildings. This corresponds to 135–180 per cent of the new construction requirement for an office building. Without an Ecopilot installation, Mektagonen would have a G-classification.
