Construction is one of the largest consumers of energy and a source of carbon dioxide emissions into the atmosphere. But at the same time, this field has the potential for smart energy use, which can yield such positive results as:
- Reduced energy consumption;
- reduction of the negative impact of the building sector on the climate;
- optimization of energy costs and their gradual reduction;
- increasing the number of jobs.
That is why we can say that the issue of energy efficiency in relation to individual buildings (both new buildings and long-standing structures) is quite acute - it is sought to improve. But how exactly is this done?
One of the most popular and affordable solutions to increase the energy efficiency of a building is the use of insulating material for its cladding. Ventilated facades are a winning solution because of their technology: they do not only include a layer of insulation, but also provide a ventilated space between the thermal insulation layer and the building envelope to increase the efficiency of the insulation. Due to the constant movement of air in the ventilated space, moisture is removed naturally and does not harm the insulation layer.
External appearance
As for the appearance of buildings with a curtain-type, rear-ventilated façade, it is often one of the determining factors. Because sometimes it happens that the building needs to fit harmoniously into a particular architectural development, and for this its appearance must meet certain aesthetic criteria. But here, too, the choice of ventfasad will be a winning option, because one of the main advantages of technology called it the architectural diversity. And all thanks to a wide choice of materials for facing - the market presents so many options in different price segments that a suitable solution for you, combining aesthetic appeal and excellent performance properties, you can pick up without much difficulty.
Restrictions related to the cladding
In this regard, it is necessary to mention the limitations associated with cladding. There are cladding materials that weigh quite a lot - for example, among these solutions can be called natural stone or concrete panels. Therefore, and choose the material should be chosen, taking into account primarily the structural load on the foundation and the entire structure as a whole. Plus the material you choose can significantly affect the cost of the facade, so the facade solution you choose must first of all be feasible, and also take into account the cost of it and the design of the project.
The legal framework vs energy efficiency
The legal framework that exists in the construction sphere, of course, imposes separate requirements for each element of the system, the quality of which is confirmed by a certificate or declaration of conformity of the manufacturer. But combining these elements into a certified system is a more time-consuming and responsible process.
The developer of the system creates albums of technical solutions, substantiates the developed fastening nodes of the system by calculations taking into account the wind loads and self-weight of the system and tests the assembled fragments of the
ventilated facade. The system designer ensures that the system uses certified components.
To confirm the safety of the ventilated façade system, the developer applies to the certification body for a technical assessment of the suitability of the ventilated façade system for cladding the walls of the buildings.
The positive result of this expert work is the issue of a Technical Certificate for the system, on the basis of which a Declaration of Conformity of the system with the safety
requirements of technical regulations TP 2009/013/BY is issued.
The presence of a technical certificate for a ventilated
façade system and a declaration is a mandatory requirement. Only certified ventilated façade solutions should be chosen.
