Fast track to climate goal: TÜV Rheinland has a new energy concept for legacy buildings

The technology group TÜV Rheinland Köln is reducing its carbon emissions by 30 percent by using an energy mix.

Ten buildings dating back to 1973 with a total floor area of 100,000 square meters have been consolidated into an innovative energy concept. These include the company headquarters in the TÜV Rheinland tower, various laboratory and office buildings, workshops, and a computer center. The core element of the new concept is an energy center. Built largely underground, it supplies all buildings on the site with heating and cooling. Renewable and fossil fuels are used for heating: Two pellet boilers, natural gas for three gas boilers, and a cogeneration plant provide the base load supply. Cooling is provided by absorption and compression refrigeration.
