Concepts and innovations
What is a passive house ?
A building says passive » has a very low energy consumption. For heating, it must be less than 15 kWh/m2/year. Such a building is very well insulated and has a fairly airtight envelope to prevent heat loss. Under these conditions, it is possible to dispense with a main heating, a single auxiliary heating such as a stove sufficient to ensure the comfort of all.
In practice, a building passive » uses the thermal calories present in its environment to ensure its heating, ie it uses solar gain or the heat given off by human activity to generate a pleasant temperature. A building labeled passive » is the guarantee of a healthy and pleasant interior since it remains temperate all year round, even in very cold or very hot weather.
The savings thus achieved are very significant, the building “ passive » spending ten times less energy than a traditional building.
In addition to being economical, this type of building takes an important step towards the ecological transition. : he has the possibility of becoming positive », that is to say, to produce more energy than it consumes. By installing certain devices such as thermal solar panels or wind turbines, the building becomes fully energy self-sufficient.
The labeling " passive » of a building is a guarantee of quality and comfort, this is what CUBÉCO wishes to offer to each of its customers. In this perspective, we are committed to respecting these standards regardless of the climate in which the modules will be assembled.
cellular concrete, a material future
Aerated concrete is an alveolar material, possessing an air volume of up to 85 %. This material is all the more suitable for modular and prefabricated architecture as it is easy to implement and transport.
The air contained in the cellular concrete provides both thermal and acoustic insulation, as well as the breathing of the building. The thermal performance is so important that it allows it to be " passive » without additional insulating material. The greatest part of energy expenditure is thus avoided and the comfort of life improved significantly.
Cellular concrete is used in CUBECO modules for load-bearing walls. It has the advantage of naturally repelling micro-organisms, molds and fungi, without any treatment. It is also very resistant to corrosion and fire. It remains stable up to 1 200°C without releasing substances that are toxic or harmful to health.
Another essential advantage of aerated concrete : its impact on the environment. It is made of natural materials – gravel, cement, lime and water – and remains, after its installation, recyclable and can be crushed and then reused.
In summary, cellular concrete is a material combining very useful physical properties, such as lightness, insulating power and robustness, with a possibility of implementation perfectly suited to the prefabrication of CUBECO modules.
The modular architecture
CUBÉCO offers innovative architecture: modular construction with cellular concrete. This is made from modules prefabricated in the factory, tested, then transported and assembled on site.
The module lifting system is patented – this is the key to successful blending. The industrialization of modules has a multitude of advantages : their manufacture, which will be done in France by qualified workers, will be rapid thanks to robotic assistance. State-of-the-art technology combined with human know-how will guarantee precision and quality.
Prefabrication avoids the vagaries of the construction site and reduces costs compared to traditional construction. The savings thus achieved make it possible to offer a 21st century architecture century combining exceptional performance and quality design, for a price accessible to all.
