PRIVA-LITE glass on the façade of the Intelligent Construction Laboratory in Cracow
January, 01, 2015

The unique Intelligent Construction Laboratory tests devices of building automation systems, thanks to which buildings are controlled even more effectively, and it is even easier and cheaper to programme them. The facility with the floor area of 1200 square metres is equipped with solutions which enable to satisfy the standards of a low-energy building, such as  e.g. heat pumps, ground-coupled heat exchangers, energy recovery systems, and solar collectors. A part of the façade of the building is covered with the PRIVA-LITE XL switchable glass.

Smart glass

The choice of the PRIVA-LITE XL in glazing units on the facade was dictated by its unrivalled level of translucency and transparency, a high safety level, and low energy consumption. The PRIVA-LITE XL installation on the façade of the Laboratory, besides the purely aesthetic and designing values, offers quite practical benefits, as well, which make it unnecessary to use blinds or shutters inside the building. It also opens up new opportunities for the use of glass. PRIVA-LITE XL can serve as a rear projection screen  that guarantees excellent image quality, and in the combination with the PVB Silence film it improves the acoustics of the building. An important advantage of the PRIVA-LITE XL glass from the perspective of architects is its dimension, equalling 1820 x 3500 mm.

‘The facade of the Laboratory with the PRIVA-LITE XL glass is a determinant of a new direction in architecture, and it demonstrates the array of opportunities offered by this solution. It is the first project of the kind implemented in Poland. In a few moments the glass façade can go from an opaque to a transparent state. This solution, combining the most advanced technology and an excellent design, can be adjusted to our individual needs. Only products such as this one can provide us with the highest level of comfort and can face the challenges of the future,’ says Magda Lipińska, Saint-Gobain Interior Market Development Manager.

 What does the innovativeness of the façade of the Laboratory consist in? What certainly deserves special attention is the smart and environmentally friendly glass. Liquid crystals located in the film between the SGG DIAMANT glass panes get arranged under the influence of the electric current, thanks to which the glass changes its transparency. When the power supply is switched off, the PRIVA-LITE glass returns to its opaque state, securing privacy, and on the other hand not blocking the source of the natural light.

In the process of implementing the project of the Intelligent Construction Laboratory, a property that was also crucial was energy efficiency of PRIVA-LITE XL. In its inactive state it does not consume any energy at all, and in its active state the installation needs it at the level of only ca. 5 W/m2. The system is controlled by  a switch, a remote control, or a specially designed timer. Solutions allowing to save energy in the interest of the natural environment constitute one of the foundations of modern, ecological construction.

Reliability guarantee

But are such innovative solutions fully safe and practical? They definitely are; what only yesterday was a song of the future, is becoming our reality today. Glass façades are a symbol of modern architecture, and thanks to the application of the PRIVA-LITE they are enriched by a new phenomenal effect. Yet another time technology has broadened the opportunities offered by innovative construction.


More and more often glass is used as an element of partition walls, doors, and floor pans in private houses, hotels, offices, or hospitals. It does not cause any limitations to contractors, at the same time offering them a number of opportunities unavailable so far. The PRIVA-LITE CLASSIC glass stands out also thanks to its care for the natural environment. It is confirmed by the Environmental Product Declaration received for it – an official document issued for construction products, which takes into account the impact of the product upon the natural environment from its production until its neutralisation.
