The three pillars of energy efficiency
The three pillars of sustainability
- Reducing energy loss
- Using energy efficiently
- Producing energy efficiently
- Economically efficient
- Environmentally friendly
- Resource-efficient
Sustainable buildings are being sought after:
- A 2008 study by the consulting firms, Ernst &Young Real Estate and Lang
LaSalle
- “If you don’t play, you have already lost”
- In the future, rental opportunities will play a much more significant role than
the construction value
Important: This applies equally for
investors, owners, and users
EVERYBODY HAS TO PARTICIPATE
BASICS
Smart action:
- The best form of sustainability is connected thought.

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 95°C (200F) possible
- Cost-effective heating and cooling through the ground

construction
Use if inadequate land area is available and deep drilling is not possible
5m drillhole with spiral drill; placed in the probe and buried in the ground
Telescopic design allowing it to be pulled out from approx. 1.2 to 3.0 m and, thus, can be
transported and installed very easily
Comparisons show that the annual total costs for heat pumps are
significantly less than those of conventional heating systems.
Example: Single-family house, new construction, 180 m², heating need 15,000 kWh, cost per
year (Comparitive calculation based on a period of 15 years)
Fuel costs
Operating/maintenance costs (chimney
sweeps, installers)
Acquisition costs (heating system, boiler/
distributed through the usage fee)
Geothermal Helix 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.

THE THREE PILLARS OF ENERGY EFFICIENCY
Top notch renovation
Holistic view with the principle of sustainability :
The high level of competence of all partners and optimized
components, interfaces, and project sequences come
together in ARGE factor 10. The goal of the free union of
well-known experts and manufacturers is energy-efficient
renovation with a significantly higher economic efficiency
than the standard - with the demand of “sinking energy
consumption by the factor 10”.
The previous successfully constructed objects speak for
themselves: www.argefaktor10.de
