Photovoltaic Ventilated Facade

PHOTOVOLTAIC VENTILATED FACADE

In addition to photovoltaic sunshades and BIPV modules, a photovoltaic ventilated facade is another way to functional and aesthetically place a photovoltaic structure in a building.

A ventilated facade, which as a standard consists of an insulation layer and an external facade cladding separated by a ventilation gap, is an energy-saving and aesthetic solution, more and more often used in new buildings and in the thermal modernization of existing buildings.

The photovoltaic ventilated facade developed by ML System not only reduces the risk of water vapor condensation and improves the thermal parameters of the building. The integration of the photovoltaic modules in the outer cladding enables the production of solar energy for the facility. The use of photovoltaics on the facade not only allows the use of RES (Renewable Energy Sources) as a building material, but is also beneficial in terms of electricity production for users who use the generated electricity for their own needs with lower consumption in summer and greater in winter (e.g. schools, universities). Such installations are never buried by snow, and also allow the production of more energy from the sun in winter compared to solutions placed on the roofs.

The unique solutions of the façade structure allow for the leveling of dimensional deviations, matching the module formats to the existing building elements and connection with other types of curtain walls. The high level of security is ensured by the construction of modules made in the glass-glass technology (laminated toughened glass) as well as by testing and certification of fasteners. Refined details, such as grilles covering the gaps between the modules, increase the aesthetics of the entire solution. The advantage of a photovoltaic ventilated facade is the possibility of replacing any module during operation without the need to disassemble adjacent elements.

The photovoltaic ventilated facade meets the architectural trends and is an attractive complement to the building's architecture. Photovoltaic cells can be arranged on a regular basis or they can be patterned. The use of a colored lamination foil with a special dye or mass tinting of the glass allows to obtain any color of the facade, and the use of ceramic printing allows any graphic element to be placed on the glass. The production capabilities of ML System also allow the creation of various shapes in the glass using a laser engraver or creating the effect of an illuminated glass by spraying between the nanomaterials (e.g. quantum dots)
