Velux Modular Skylights have been installed at the Siemens head office building in Ballerup, just outside Copenhagen. The large atrium ridgelight solution consists of six rows of
VELUX Modular Skylights which ensures substantial amounts of daylight resulting in a bright and pleasant space.
To evaluate the indoor climate in the finished building, the project was tested in advance with VELUX Energy and Indoor Climate Visualizer. Following the results, Siemens chose to
fit all modules with integrated roller blinds in white colour. In terms of energy efficiency, the protection against cold bridging is a defining quality of the product and was one of the important reasons for choosing VELUX Modular Skylights in Ballerup.
All 228 VELUX Modular Skylights are fitted with fully integrated, white roller blinds. Contrary to darker fabrics, white blinds has a much higher light transmittance, providing more daylight to the interior even when the blinds are closed. In other words, the blinds will protect against glare, but not inhibit the lighting effect of the skylights. The main purpose of the blinds at Siemens Head Office is to protect against excessive heating from the sun. Especially in the summertime the large atrium would be exposed due to the shear size of the solution.
