Summary

The office building of the Colonia Headquarters, with a net area of almost 70,000 square meters, is equipped with a "supporting supply-and-exhaust ventilation system". Simultaneously the building has openable windows which can be used for ventilation during favourable weather conditions. Over a period of 10 years the outdoor climate conditions and the opening time of the windows were recorded. They are open nearly 40% of the office time. The air conditioning system for the office area accounts for 20% of total electrical energy consumption, whereas the costs for electric energy amounted to 86% of the total energy costs.
