GIRAFFE VS GIRAFFE 2.0
RENEWABLE ENERGIES
RENEWABLE MATERIALS
PERFECT SYNERGY
How does the Giraffe work?
The Giraffe is a hybrid power station ready to charge anything
from your e-vehicle to your home – by capturing energy of the
wind and sun.
This futuristic yet natural construction comprises a wooden
structure supporting solar modules as well as a wind turbine.
Intelligent positioning of PV panels in 12-20 different angles
allows for stable energy production – providing solar energy

mounting
The Giraffe can be equipped with various wind turbine
solutions from 1,75 to 3,5 kW
The solar panels provide power capacity between 4,0 (Giraffe)
and 6,0 (Giraffe 2.0) kWp.
Giraffe: stable energy production
complementing solar with wind power
The Giraffe is able to produce 5 000 – 13 000 kWh per year even in countries with low solar
radiation and moderate winds – providing power 24 hours a day, all year round

Giraffe vs Giraffe 2.0 – Stronger & More Durable
Higher strength thanks to glulam
enabling a bigger rotor turbine
Less reinforcement / wood needed
to achieve higher strength
giving the V.II a more
harmonious design
Stronger with less metal:
long GL beam replaces bolt assembly.
Connections are less complex and more robust

Wood & CO2
Wood has the unique ability to capture and store CO2 while reducing carbon
sources
There are two ways to reduce CO2 in the atmosphere:
  reduce emissions or “carbon sources”
  remove CO2 and store it - increasing “carbon sinks”
Wood has the unique ability to do both.
Each cubic metre of wood saves a total of 2 tons of CO2. Every cubic metre of wood
used as a substitute for other building materials reduces CO2 emissions by an average
of 1,1 ton CO2. If this is added to the 0,9 ton of CO2 stored in wood, we get a total
of 2 tons CO2

forests which are left in a natural state. Younger trees,
in vigorous growth, absorb more CO2 than mature
trees, which will eventually die and rot, returning their
store of CO2 to the atmosphere, while most of the
CO2 of the trees harvested from a managed forest
continues to be stored throughout the life of the
resulting wood product.
InnoVentum always procures wood grown in
sustainably managed forests.

CO2 balance of the Giraffe 2.0
Giraffe 2.0:
-  Use of wood contribution, offsetting - 4700kg of CO2
-  Use of steel components, carbon footprint: 40 kg of CO2
  CO2 balance - 4700 kg + 40 kg = - 4,660 kg
Considerations:
1m3 of wood replacing steel offsets 1500 kg of CO2 (incl. transportation and processing of wood)
582 kg CO2 is emitted per ton of steel manufactured
Density of steel: 7850 kg/m3
- 4,6 tons

Conclusion: Giraffe 2.0 - more than carbon
neutral
