The three pillars of the power: reduction of the losses, production and efficient use
The concept of energetic efficiency engloba so much the reduction of the loss like the efficient use of the power. From it does more than 50 years,
The group of the solutions for the energetic saving bases in three big concepts: the reduction of the losses, the production of power and the efficient use of the same.
Reduction of the losses
An important part of the air conditioning of the interior of the building loses owing to the presence of thermal sensors bridges. The modern systems of window and enclosures of PVC of Rehau reduce notably the losses and the energetic costs, already was in the new constructions as in the works of rehabilitation of buildings. The perfect structure of the cameras and of the typical boards of the profiles of window Rehau (with value Uf of until 0,85 W/m²K) allow to keep in the interior of the building the heat in winter and the cold in summer without detriment of the necessary transpiration of the external walls of the house.
Thus it is important the selection of an energetically efficient system for his windows. The system Geneo manufactured with Rau-Firpo, a material of high technology reinforced with fibres, allows in the majority of the cases dispense of the metallic reinforcement, avoiding thermal sensors bridges and saving until 76% of power, that usually loses through the conventional windows.
Efficient use
Once resolved the problem of the uncontrolled dispersion of the heat and of the power, is precise to occupy of the optimisation of the thermal sensors distribution in the interior of the building. The systems of heating and of refrescamiento distinguish by his low energetic consumption and by the distribution homogénea and controlled of the power.
The systems Rehau offer an unprecedented flexibility under multiple appearances: for his energetic supply employ sources of alternative power such as the geotermia and the solar power, respecting fully the principle of the aprovechamiento responsible of the natural resources. The systems of heating and refrescamiento by radiant surfaces, available so much in version for floor, wall and ceiling, can install already was in buildings of new work as in works of rehabilitation. The systems of heating and refrescamiento Rehau guarantee a high qualitative standard of confort and of welfare. In diet of heating the system does to circulate the hot water by the interior of the serpentines and the heat distributes of uniform way thanks to the wide surface of radiation of the installation. Besides, the special distribution of the temperature, that makes possible the regulation by zones, allows to keep the temperature of the water of the installation to an optimum low level, reducing of remarkable way the costs and the consumption of power.
Efficient production
The sources of renewable energies, ecological and respectful with the climate, represent the guarantee of the energetic procurement for the future generations. To face up to this exigencia is precise to begin to work immediately in this steering, incentivando the production of pertinent power of renewable sources. To day of today, the aprovechamiento of such energetic sources allows to reduce considerably the consumption of the fuels fossils. The geothermal sensors systems take advantage of the present thermal sensors reservations in the subsoil by means of the use of probes and manifolds: the thermal sensors exchanger earth-air Awadukt of Rehau, in combination with a device of mechanical ventilation controlled with recovery of the heat, ensures the heat in winter and the freshness in summer, in addition to guaranteeing a significant reduction of the costs of the power.
Likewise, by means of the aprovechamiento of the power of the subsoil, is possible to satisfy the energetic requirements of the system of heating and refrescamiento. To take advantage of the pertinent heat of the earth Rehau has created Raugeo, a geothermal sensors system composed of tubes, thermal sensors probes and manifolds. The probes are exchangers of installed heat in the perforaciones realised in the terrain and connected to a bomb of heat and to a hydraulics system that resupply of heat or of cold according to the exigencias of the system.
In the thermal sensors solar systems the enclosed circuit of the manifolds heats directly by means of the solar radiation, that to his time transfers the power to the water of the hydraulics circuit of the building. Thanks to the state helps and to the constant process of optimisation of the performance, of the manutención and of the functional hygiene, the systems Rehau can take advantage of to the maximum his potential.
