Building envelopes have already started to provide several functions. For industrial buildings, the energy efficiency retrofit is becoming more important. Energy suppliers like innogy SE want to offer their customers the smart idea of generating power on the façade and simultaneously saving costs and contributing for climate protection. The Lechwerke AG, a regional energy supplier that belongs to innogy SE, is now evaluating several solar technologies.
As part of the project “energy façade,” which launched three years ago, two areas of their southern façade have now been equipped with SVK fiber cement elements covered by HeliaFilm. A total area of 56 square meters with an installed capacity of 2.43 kWp is expected to deliver an estimated yield of about 2000 kWh per year.
The low weight of the films (1 kg/m2) allows for an easy and low-cost integration both on new and existing façades. Aesthetics also played an important role in the façade design at Lechwerke Augsburg. The HeliaFilm solar films set visually appealing accents, with a light background on bright fiber cement elements.
