Window film Energy efficiency

The European Union and European governments are looking to use 20% less energy by 2020 and thereby also reduce their CO2 emissions by 20%. The use of air-conditioning throughout Europe has doubled in recent years and is likely to double again over the next decade.

The International Energy Agency is predicting an increase of 60% in primary energy consumption by 2030. The building industry in Europe is responsible for 40% of energy consumption. On the other hand, sources of fossil fuels are becoming depleted, resulting in a likely increase in the price of energy. The Kyoto Protocol also commits governments to reduce emissions of greenhouse gases. In order to achieve this goal, the European Parliament has approved the Energy Performance of Buildings Directive. This directive has been in force since 1 January 2006 in the member states of the European Union.

The cost of cooling a building is often more than heating it. And air-conditioning systems are less efficient if they are subject to large temperature differences. Extra capacity is required to compensate in that case. The most obvious source of high temperatures in buildings is solar energy. The installation of Umisol® window film considerably reduces the cooling capacity required from the air-conditioning, resulting in savings on cooling costs of up to 25%.

Umisol® window foils also provide increased thermal insulation during the winter.
These foils keep out the summer heat, while their insulating effect reduces heat loss through the windows. 
This results in savings on heating costs of up to 30%.

This energy-efficient solution generates annual energy savings and a faster return on investment.
CO2 emissions are reduced considerably, so your ecological footprint is smaller.

Umisol Group NV is committed to sustainable business

  • energy costs savings.
  • longer retention of your existing glazing so there is less waste and less use of raw materials (no new glass to install). Not replacing the glass also means no processing or recycling, and therefore extra energy savings.
  • The energy consumed in the manufacture of new glazing is greater than the energy used to produce foil, so that is also saved.
  • The transport costs for foil are very low compared with those for new glazing because glass is heavier and the quantities required are larger.

Umisol Group NV has also developed an Energy Saving Simulation Program (ESSP) to help engineers, architects and building owners with their energy-performance analysis.

This software program calculates the effect of Umisol® window film on heating and cooling costs. Dozens of parameters can be introduced into the program, including outside climate, façade orientation, glazed surfaces per orientation, light and energy properties of the existing glazing, heating and cooling system yield, electricity and gas prices in kW/h, degree day calculations, CO² emission reduction, ROI calculations, etc.

The use of ESSP is part of a total advice solution that Umisol Group NV offers its customers so energy management and consumption can be calculated.
