Siemens ceaselessly strives to make its buildings more sustainable. Siemens’s new HQ in the heart of Munich is proof of this: a veritable model of energy efficiency, it consumes 90 % less electricity and 75 % less water than the old one and has cut its CO2 emissions by 90 %.

It is one of the most modern and sustainable office complexes in the world. From the outset the new HQ was thought out to be more open, innovative and, above all, more energy efficient than the old one. To such an extent that it supplies a large proportion of its energy itself.

Geothermal energy and rainwater recovery

Geothermal energy, for example, plays an important role in the building’s heat regulation. Nearly 100,000 liters of water are pumped per hour into the 70 km network of pipes placed in the foundations before circulating throughout the building to heat or cool it depending on the season. The facades of the open interior patio are fitted with large windows that allow a maximum amount of natural light to enter. Nearly one million and half liters of rainwater are collected on the roof and used, among other things, for the toilets. Lastly, practically one third of the electricity required for the building’s functioning is provided by solar power.

Technology signed Siemens

Quite logically, Siemens uses its own technology to save even more energy. It is thus that a Desigo building technical management system collects and analyzes the data relative to the complex’s heating, ventilation, lighting and cooling. Associated with the Total Room Automation (TRA) concept, it is used to control all the technologies in the most energy-efficient way possible. To conclude, we can say that Siemens has designed the building of the future. Because its new central HQ doesn’t just meet the company’s own needs, it also contributes to improving the quality of life in an urban space. In short, it’s a smart building that participates in the development of a smart city.
