When it comes to the careful handling of resources and protecting the environment Koelnmesse is implementing a number of processes and expanding already established measures. These actions contribute to improving the energy balance of the individual events and the administration building alike.

High-energy efficiency thanks to modern technology
The energy balance in the trade fair halls and the administration building are being continuously improved. Electricity and gas consumption are being effectively reduced and power is being used only to the degree that is actually required.

For example, during periods when there is no trade fair activity the lighting fixtures in the halls are controlled by presence sensors. Areas that receive a generous amount of daylight were incorporated into the halls during construction. Ventilation control is set up to respond to the air quality. When it comes to cooling the halls, two positive measures are important: Koelnmesse has increased the energy efficiency of the air conditioning equipment and also completely converted to environmentally friendly refrigerants. In the Koelnmesse administration building, energy is being conserved through more efficient building control technology.

In addition to this, Koelnmesse is investing in energy-saving technology as part of its modernisation programme Koelnmesse 3.0. One of the important measures consists of the company's own a combined heating and power station (CHP plant), which will work according to the combined heat and power principle to produce both electrical energy and heat. The economical and ecological idea behind this is that the energy produced is used directly on site to provide the required electricity. Koelnmesse's new energy concept will serve to reduce annual CO2 emissions by 3,200 tons in the first year alone, which equals the emission of approximately 410 single-family homes.

Recyclables management
The Koelnmesse waste concept ensures that refuse from the materials used for stand construction is separated according to waste type in the purest possible manner. Significantly more than 90 per cent of the waste generated in a year is recycled.

In addition, many stand elements — such as carpeting and individual walls — are reused at a number of trade fairs.

Traffic guidance and mobility
During large trade fairs Cologne experiences an unavoidably increase in traffic. With the close cooperation of the traffic department of the city of Cologne and through the promotion of local public transport, Koelnmesse’s logistics concept ensures that exhaust emissions and negative influences on street traffic are significantly reduced.

Logistics experts use modern IT technology to manage the traffic related to stand construction and dismantling. For example, lorries with a gross vehicle weight of 3.5 tonnes and more are directed to a specific parking area right next to the exhibition centre. In this way, lines of lorries waiting on the street with the engine running are avoided, eliminating damaging emissions.

Koelnmesse encourages the use of the public transport network. Event admission tickets are valid for travel on trains, trams and buses of the Verkehrsverbund Rhein-Sieg (VRS). This measure is facilitated by the fact that the Cologne exhibition grounds are optimally situated. The Köln Messe / Deutz train station as well as a tram stop are located only a few steps away. The use of public transport is not only practical for trade fair participants; it also reduces street traffic, thus protecting the environment.
