Energy-efficient construction

Sustainable and economical solutions

Energy-efficient construction  
As a skilled system provider for energy-efficient construction, REHAU actively and sustainably contributes to shaping the future. For over 50 years, the polymer specialist has researched, developed and marketed integral solutions for the construction industry - from private residential premises to blocks of flats to industrial, commercial and administrative premises. Cooperation with dena as well as partnerships with initiatives like EnergieRegion Faktor 10 and ARGE Faktor 10 underline the Europe-wide and worldwide dedication of the company to environmentally-aware and responsibility-conscious construction and redevelopment. Of special note here are the three pillars of energy efficiency: "Reducing energy losses", "Efficient energy usage" and "Efficient energy generation".

Reducing energy losses
Modern window and curtain walling systems reduce energy losses and operating costs, both in new constructions and during modernisation. Thanks to its sophisticated construction of chambers and seals, it is able to keep heat inside the building without interfering with the breathing of the building envelope. With GENEO, REHAU offers the most energy-efficient solution of its class. With a rated value of up to Uf, BW = 0.8 W/m2K, GENEO is highly heat insulating and it does so at low view widths, which enable more exposure to light and improved aesthetics. Thanks to integrated function chambers for additional heat insulation and three-pane insulating glazing, the level of a passive solar house can be achieved at considerably reduced costs than were previously possible. GENEO window profiles help to protect resources, reduce CO2 emissions and save money.

Efficient energy usage
Underfloor heating and cooling systems contribute to optimised, efficient heat distribution in buildings thanks to their comparably low levels of energy consumption as well as their consistently comfortable ambient temperature distribution. The innovative REHAU systems feed their energy from alternative sources like geothermal and solar energy. Underfloor heating or cooling from the construction expert for flooring and walling come into consideration and are used in wetwall and drywall construction in new constructions as well as in redevelopment work.

Efficient energy generation
Renewable energies represent the safe and sufficient supply of power for future generations. REHAU's heat pumps are especially efficient when it comes to energy usage. This is because, from the 100 per cent heat energy fed to the heating system, some 75 per cent of it comes for free straight from the environment and only a quarter of extra energy in the form of electricity is required. This is achieved by using high-quality coordinated heat pumps and system components. REHAU is the only company on the market that can provide everything from a single source. The individual components are optimally aligned with each other as early on as the development phase.

In order to generate the necessary energy, the use of geothermal heat can be considered. Using geothermal probes and collectors, heat is extracted from the ground - regardless of weather and time of year - with the help of closed circuits, and then used for heating or cooling. In combination with a heat recovery device, the AWADUKT air and geothermal heat exchanger system employs monitored ventilation for heating in Winter and cooling in Summer, while improving the ambient environment and saving on energy costs. Installing solar heating systems is equally sensible. This can save up to 70 per cent on energy costs for heating drinking water and up to 35 per cent on heating support. The high degree of efficiency, simple and flexible assembly as well as safe constructions make it possible to use the system in both old buildings and new ones.
