One of the tallest skyscrapers in the European Union is Poland’s Varso Tower. It was built with energy efficiency in mind. The glass elements use Swisspacer Ultimate warm edge spacer bars.

The tower is in the middle of Varso Place as one of a three new buildings in the centre of Warsaw (Latin name Varso) right next to the central railway station. All three buildings have been awarded the BREEAM Outstanding certificate and the WELL Building Standard.

The main Varso Tower was conceived by the Foster + Partners architectural studio, and the two lower office buildings Varso 1 and Varso 2, were designed by Hermanowicz Rewski Architekci from Warsaw.

Varso Place offers a total of 144,000 square meters of high-quality office and hotel space.

Energy and comfort

An important factor of the project was to offer users a high comfort level. The WELL Building Standard places a strong emphasis on health and well-being of building occupants. They must be demonstrated in categories ranging from light and air quality to thermal comfort and the environmental compatibility of building materials.

At the planning stage of the glass façades of Varso 1, attention was paid to optimum daylight gain along with thermal comfort. To meet the project requirements, triple glazing units with Cool-Lite SKN 176 II solar control glass from Saint-Gobain Glassolutions and the Swisspacer Ultimate spacer bars were used. A special coating of highly selective solar control glass ensures high daylight illumination of the interior and neutral colour tones when looking out. At the same time, infrared radiation is effectively absorbed and heating of the interior is prevented.

The Swisspacer Ultimate premium spacer bar has a very low thermal conductivity (lambda value) and therefore insulates the edge of the glass unit.
