8 SUSTAINABLE TECHNICAL SOLUTIONS FOR CLIMATE PROTECTION The three pillars of energy efficiency The main works under one roof Reducing energy losses Using energy efficiently Producing energy efficiently Building envelope Building technology Energy supply REHAU - Energy Efficiency and Sustainable Construction - October 16, Page 8

9 COMPLETE SYSTEM REHAU CONSTRUCTION FOR ENERGY EFFICIENCY Producing energy efficiently Using energy efficiently WINDOWS Reducing energy losses SOLAR HEAT PUMP AIR/GEOTHERMAL HEAT EXCHANGER RADIANT HEATING GEOTHERMAL REHAU - Energy Efficiency and Sustainable Construction - October 16, Page 9

10 REDUCING ENERGY LOSSES Optimization of the building shell under technical and economic aspects with REHAU systems REHAU GENEO - The new dimension in window construction The fully-reinforced window profile made from the high-tech material, RAU-FIPRO The innovative material recipe by REHAU offers the highest level of stability and torsional rigidity as well as static properties that were previously not possible without steel. GENEO PHZ is available as an additional developmental stage. GENEO PHZ has become a certified window solution for passive houses by incorporating foam inserts and a special middle seal. *Reduction of the energy loss in windows by changing out the old wooden/vinyl windows from the 80s (Uf=1.9, Ug=3.0) to windows made from GENEO profiles (Uf=0.91, Ug=0.5, window size123 x 148cm) REHAU - Energy Efficiency and Sustainable Construction - October 16, Page 10

11 REDUCING ENERGY LOSSES REHAU - Energy Efficiency and Sustainable Construction - October 16, Page 11

12 USING ENERGY EFFICIENTLY Optimization of the distribution of heat through a surface heating/cooling system Minimal energy consumption and high level of comfort with REHAU systems - Reduction of operating costs by approx % - Low temperature system with flow temperatures of F (depending on the ground structure) - Possible use of alternative energy sources (WP) - Special solutions for renovations For all areas of use in residential and office buildings Elaborate solutions for structural elements, floor, and wall surfaces For heating and cooling in wet and dry construction. Save 63% of your energy costs WITH THE ENERGY COMFORT SYSTEM REHAU - Energy Efficiency and Sustainable Construction - October 16, Page 12

13 PRODUCING ENERGY EFFICIENTLY The use of advanced technologies for utilizing geothermal heat and solar energy - Geothermal energy probes or collectors - Heat pump applications (GEO, AERO, AQUA) In conjunction with surface heating and cooling systems and / or Concrete core temperature control Heat pump - Solar thermal energy - Air and geothermal heat exchanger Reduction of the demand for primary energy and, thus, exhaust gases (e.g.: CO 2 ). REHAU - Energy Efficiency and Sustainable Construction - October 16, Page 13

14 PRODUCING ENERGY EFFICIENTLY System cycle air / geothermal heat exchanger Alternative possibility for heating and cooling via a controlled ventilation system, particularly in low-energy and passive energy houses. 85 F Intake temperature on the suction element 60 F Discharge temperature at the end of the air/geothermal heat exchanger Air and geothermal heat exchanger, AWADUKT Thermo Hygienic fresh air through antimicrobial inner layer of the pipe PP material with optimal heat transfer High longitudinal stiffness for securely diverting condensation System from the point of suction to heat recovery Improvement of the air quality in the building Reduction of heating costs through prewarming of the exterior air Pleasant cooling effect in the summer 5 F Intake temperature on the suction element 55 F Ground temperature 45 F Ground temperature 35 F Summer Discharge temperature at the end of the air/geothermal heat exchanger Winter REHAU - Energy Efficiency and Sustainable Construction - October 16, Page 14

15 PRODUCING ENERGY EFFICIENTLY System cycle geothermal heat / geothermal energy - Energy resources that are available day and night and during any type of weather free of charge. Energy resources that are - continuously renewed through the inside of the earth and - through the suns rays on the surface. RAUGEO probe / collect - No welded connections in the ground, thus the highest level of operational safety - Due to the material, PE-Xa, no hazard from notches or score marks - Optimal security when inserting into the drilled hole because the probe foot is protected with a special resin - Easy insertion, even in the smallest drilled holes - Heat storage up to 203 F possible - Cost-effective heating and cooling through the ground RAUGEO Manifold Heating/ Cooling Heat Pump RAUGEO Collector RAUGEO Probe REHAU - Energy Efficiency and Sustainable Construction - October 16, Page 15

16 PRODUCING ENERGY EFFICIENTLY Geothermal heat collectors Use in new construction (especially in low-energy houses) as well as in the renovation of older construction Use if the appropriate land area is available and deep drilling is not possible Horizontal installation at a depth of approx. 5 ft Normally, sandbed-free installation is possible REHAU - Energy Efficiency and Sustainable Construction - October 16, Page 16

17 PRODUCING ENERGY EFFICIENTLY Geothermal heat collectors Geothermal heat probe Normally used in new construction, but also possible if there is good access in the buildings Used if there is little land area Vertical installation at a common depth of approx.: ft High level of effectiveness through the material properties geothermal heat probe complete without welding joints REHAU - Energy Efficiency and Sustainable Construction - October 16, Page 17

18 PRODUCING ENERGY EFFICIENTLY Geothermal heat collectors Geothermal heat probe Telescopic spiral probe Use in new construction (especially in low-energy houses) as well as in the renovation of older construction Use if inadequate land area is available and deep drilling is not possible 17 ft drillhole with spiral drill; placed in the probe and buried in the ground Telescopic design allowing it to be pulled out from approx. 4 to 10 ft so can be transported and installed very easily REHAU - Energy Efficiency and Sustainable Construction - October 16, Page 18

19 PRODUCING ENERGY EFFICIENTLY Geothermal heat collectors Geothermal heat probe Telescopic spiral probe Energy piles Use in new construction for statically necessary bored pile foundations The RAUGEO collect PE-Xa pipe is also excellently suited for the integration in foundation piles. Because the foundation piles, and thus, the associated civil engineering are necessary, only minimal additional costs are acrued through the integration of the system.
