As a result of global warming, energy efficiency and conservation have become critical considerations when designing a structure. Today, a typical building accounts for 40% of overall energy usage. The facade acts as a transition between indoors and outdoors and is critical in determining a building’s energy efficiency. By utilising a back ventilated facade, an energy concept for each building can be established that considers the building’s heating and cooling requirements and the ideal light quality inside.
In recent years, ventilated facade systems have gained popularity in new construction and building rehabilitation, resulting in surprising outcomes that transform the appearance of previously degraded structures. Its popularity stems from the fact that this system improves the energy efficiency of buildings by a significant margin, resulting in increased tenant comfort. When utilised in new construction, their advantages include ease of maintenance, reasonable cost, and longevity. Furthermore, the remarkable malleability of certain materials enables the creation of daring and eye-catching designs without jeopardising the building’s structural integrity or energy efficiency.
Ventilated Facade System:The ventilated facade is an enclosure system that uses a supporting framework to allow an insulating layer and an outer leaf to be put on top of an inner leaf. The separation gap between the layers allows a current of air to flow between the insulation and the coating, creating a natural ventilation “chimney effect.” This action warms the vented facade in the summer and circulates the air within the chamber, replacing the heated air with cooler air by heat transfer through convection. During the winter, however, the air in the chamber/room is heated but not sufficiently to circulate and replenish itself.
Benefits of Ventilated Facade System:It has three main benefits for the building:
Thermal
- A reduction in the quantity of heat that buildings absorb in hot weather circumstances due to partial reflection of solar radiation by the exterior facade and the naturally ventilated air cavity.
- In cold weather conditions, ventilated walls store heat, resulting in a lesser dependency on heating.
- HVAC power usage accounts for around 40% of overall building electricity consumption. According to research, ventilated facade systems may easily save over 30% on energy usage.
Acoustic
External noise is reflected more effectively using ventilated facade systems, with a recent Australian project achieving an average decrease of up to 8dB. Because road traffic noise is one of the most common external noise sources impacting buildings. Lowering the noise may substantially enhance the occupant’s comfort.
Structural
In addition, a secondary facade offers wind and rain protection. The cavity’s natural bottom-to-top circulation aids in removing moisture from the facades, avoiding mould and water infiltration, and ultimately extending the structural integrity and longevity of a structure.

Design of Ventilated Facade System
A ventilated facade system must comply with stringent industrial design requirements, thus making decisions during the design process is critical to minimise subsequent improvisations. Before installing a ventilated facade system, one must decide the cladding materials, facade design, and final structural plans.
The layout planning and measurements are the first steps in the system installation. Intervals or spacing are measured, and brackets are fastened in them based on the sizes of the slabs and joints. The vertical aluminium or steel substructure is attached to the brackets, secured at prescribed intervals, and thermal insulation is placed. Finally, the module’s wall cladding is installed, resulting in the development of an air gap. The air gap must be properly dimensioned to allow optimum ventilation across the facade.
The two installation techniques, the horizontal installation system and the vertical installation system, determine the kind of anchoring: exposed anchoring or hidden anchoring. The vertical installation technique is used in ventilated facades with visible anchoring, whereas the horizontal installation system is used in ventilated facades with concealed anchoring. The beauty of the facade and the cost of the wall covering determine the best anchoring option.
As the usage of vented facades as a building envelope alternative has grown in popularity, various options have emerged on the market, ranging from aluminium composites panels to wood or ceramics.
Aluminium Composite Panel
It is a material made up of two aluminium sheets and a plastic or mineral core within. It offers outstanding mechanical qualities, such as flatness, durability, and maintenance simplicity.
Aludecor ACP Sheets have the following characteristics:
- Dimensional stability is the capacity to size material without it deforming.
- Thanks to the different assembly techniques, installation is quick and straightforward.
- A wide selection of finishes is available.
- Superior durability, corrosion and weather resistant
- Due to the low density of aluminium, they are incredibly light.
Wood
A laminated board consisting of compressed and treated fibres with a natural wood veneer make up wooden panels for ventilated facades. A coating is applied to the plate to protect it from UV rays and other atmospheric pollutants and against fire.
Ceramic
One of the most popular and widely utilised coatings is ceramic. It’s a low-maintenance material that’s simple to lay and replace in the case of damage. It is also a superb acoustic insulator.
The technology underlying ventilated facade systems reveals its overall advantages and benefits over conventional and other modern facade systems. The ventilation process’s capacity to employ air, a renewable resource, is a standout feature of the ventilated facade system. This characteristic distinguishes the system as a “ventilated facade.” The constant ventilation in the air gap allows for dry insulation of the walls and slabs while also expelling moisture from the interiors, maintaining a suitable indoor temperature.
The ventilated facade systems have a tremendous aesthetic influence on the building. Once in place and installed, the technology’s operation will improve the building’s performance by enhancing the comfort and well-being of the residents. Build your ventilated facade withAludecor Systemsto enjoy superior aesthetic, durability, safety and zero undulation.
Ventilated facades from Aludecor are exterior finishing solutions with space that allows air to pass through the gaps between the panel and the facade to improve thermal insulation. These facades assist the building in conserving energy and therefore lowering costs. The gap between the facade and the building lowers thermal transmission and the amount of heat that enters the building from the outside in the summer and vice versa in the winter. This saves energy and reduces cooling and heating costs within the building – Read More.
