ACCESSIBILITY AT UNOG A A A A The United Nations in the Heart of Europe

The Palais des Nations

The United Nations Office at Geneva (UNOG) is the second largest United Nations centre after the United Nations Headquarters in New York. UNOG is housed in the Palais des Nations, an outstanding testimony to twentieth century architecture, situated in a beautiful park in Geneva overlooking Lake Geneva, with a splendid view of the Alps and, on a clear day, the Mont Blanc.


Concrete actions in buildings management follow the policies of the Secretary-General to protect the environment and fight global warning:

Air conditioning from water from Lake Geneva
In 2009, UNOG buildings were connected to “Genève-Lac-Nations” (GLN). This project, developed by the “Services Industriels de Genève” (SIG), aims to use renewable energy, i.e. water from Lake Geneva, to cool the Palais des Nations and its conference rooms.

Solar energy
UNOG has installed 60 m2 of solar panels for the production of hot sanitary water in buildings A,B,C,D,K and S. With the support of Green Cross International, 20 sola lamps have been installed in the Ariana Park.

Energy-efficient Lighting
Energy-efficient Lighting and motion sensors have been installed throughout the Palais helping to contribute to a reduction in energy consumption.

Water efficiency
The replacement of pipes and flushing units, as well as double-flush toilet systems, has helped to reduce water consumption.

Natural gas
The Palais des Nations was kept warm in winter with heating oil. This energy source has been replaced with natural gas which has led to reductions in emissions of CO2.
