Swisspacer’s Ultimate warm edge spacer bars have been installed in a section of Varso Place, a complex of three new buildings in Warsaw, Poland, that contains the tallest skyscraper in the EU. The three buildings have been awarded an ‘Outstanding’ certificate from the Building Research Establishment Environmental Assessment Method, and the WELL Building Standard. They are among a small number of buildings in Poland that have obtained such a high level of energy certification. The main tower was conceived by London-based Foster + Partners architectural studio, while the two lower office buildings were designed by Hermanowicz Rewski Architekci from Warsaw.
Connected by a glass lobby, the Varso One and Varso Two buildings form an architectural and functional unity with the Varso Tower. The 90- and 81-metre-high glass towers rise from a cascading podium with a stone façade. Intricately designed windows, with glazing located in two planes, feature between large limestone slabs.
At the planning stage of the glass façades of Varso One, 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 were used, as well as Swisspacer’s Ultimate spacer bars. A special coating of highly selective solar control glass ensures daylight illumination of the interior and neutral colour tones when looking out. The system ensures that infrared radiation is effectively absorbed, preventing internal overheating.
