Castell-Bank Würzburg
Sun protection films for more energy efficiency and safety in the Fürstlich Castell’schen Bank Credit Casse AG
Problem:
Intense heating up of room temperature due to solar radiation.
Solution:
Bruxsafol Sun Protection Film LX-70
Amount of Film:
approx. 58 m2
Benefits:
Reduction of respective room temperatur by an average of 5 °C.
Fürstlich Castellsche Bank Credit Casse AG employs around 270 people in 14 branches and representative offices in Heilbronn and Munich. The bank’s listed headquarters are located in Würzburg, directly on Würzburg’s market square. Due to the nature of the window fronts – these are large, double-glazed wooden windows – the room temperature steadily increases. With this in mind, the decision makers were looking for a cost-effective solution that, on the one hand, offers a high level of sun protection against heat radiation and thus sensible temperature control, but on the other hand does not damage the valuable building structure. The decision was made in favor of the LX-70 Ultimate sun protection film from BRUXSAFOL.
Measurable success:
The glass-film composite creates a light transmission of 72%, an infrared reduction of 95% and UV absorption of 99%. As in the case of the Fürstlich Castell’sche Bank, the loss of light in the visible spectrum is not relevant to the human eye. Another beneficial function is that metal-coated films offer reliable shielding insulation. This applies to high-frequency and electromagnetic waves that can penetrate from outside to inside as well as radiation that can penetrate from inside to outside through window facades. In addition to protection against so-called electrosmog, the aspect of information protection is a decisive factor here.
Conclusion:
In the case of the Fürstlich Castell’sche Bank, the rooms are on average of up to 5 °C cooler than before thanks to the film. In addition, the reduced cooling load on existing air conditioning systems results in noticeable savings in terms of energy consumption. Solutions such as film installation often pay off, especially in older buildings. New glazing is not only more expensive, but can also cause damage to the structure, which is not possible in many cases. The building and its glass surfaces were not visually changed by the installation of LX-70.
