The Coca-Cola® Services Building becomes more Energy Efficient retrofitting its windows with Umisol®.

Umisol® Infrared Blocking Filter installed in Coca-Cola® HQ in Brussels.

Most buildings waste energy and are expensive to maintain. Built before energy efficient practices, most existing buildings waste energy through insufficient heating and cooling systems, poor insulation and inadequate single or double pane windows.
Energy efficiency is central to the European strategy with the 2020 - 2030 - 2050 EU Directives for smart and sustainable growth in the EU and the progression to a resource-efficient economy. By 2050 the EU aims to significantly reduce emissions by 80-95% compared to 1990. The greatest potential for energy saving exists in buildings. The Commission’s plan regarding energy focuses on instruments to get the renovation process for public, commercial and private buildings underway and to improve the energy performance of the components used in those buildings. Improving the glazing with Umisol IR Filters is one of the opportunities and can give new life to existing buildings.

Re-Inventing the Windows

The existing windows in the Coca-Cola® Building were double glazed. To improve the solar gain value (g-value) Umisol® installed her coated IR film on the 510 windows for a total of 1.660m² for the price of 99.576 €. This glazing retrofit creates a profit of 14 €/m²/year. The extremely efficient insulating and transparent modern technology from Umisol® permits maximum insulation in order to maintain the most constant temperature and optimizes your cooling and heating. Umisol® solar films offer effective solar control properties during summer and an energy-efficient thermal insulation during winter and improve the indoor comfort.


The Umisol® IR Filters were recently included in the GreenQuest Mission of ABN AMRO BANK and COFELY as one of the 6 recommended measures to realize a CO2-neutral office. For the insulation of the head office in South-Amsterdam ABN AMRO BANK installed around 12,000m² Umisol® films. Other retrofit projects include the Department of Environment and Kyoto of the European Commission and the European Parliament Building.
