1 EVOLUTION: GIRAFFE VS GIRAFFE 2.0 RENEWABLE ENERGIES RENEWABLE MATERIALS PERFECT SYNERGY

2 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 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.

3 Giraffe: stable energy production complementing solar with wind power The Giraffe is able to produce kwh per year even in countries with low solar radiation and moderate winds providing power 24 hours a day, all year round kwh kwh

4 Six months after starting Research & Design, the Giraffe had reached spectacular venues (I) OFFGRID DECENTRALIZED POWER STATION AT THE EUROVISION VENUE Powers lights,, outlets for electronic devices. It can become a perfect spot for picnics, children s playgrounds and a Malmö Hyllie near Malmö Arena (Eurovision Song Contest 2013 venue):

5 Six months after starting Research & Design, the Giraffe had reached spectacular venues (II) URBAN PARKING E-VEHICLE CHARGING STATION IN VÄSTRA HAMNEN, MALMÖ Charging electric vehicles in urban environment. Preferred place for EV-related events and activities. Malmö Västra Hamnen (Öresund Electric Car Rally & Green Vehicle Days 2013):

12 Giraffe vs Giraffe 2.0 More Power Higher = Better +3m longer neck to avoid wind turbulence and reach higher wind speed In addition, a more powerful wind turbine with 5 times larger swept area, and generator increase from 1.75 kw -> 3.5 kw > 3000 kwh more per year 6,0 m 12,0 m 9,0m 2 Middle Row added +8 PV Modules for higher production > kwh more per year 2,3 m 3,3 m kwh per year 4,1 m

13 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 Giraffe Giraffe.2.0

16 of the Giraffe and Giraffe 2.0 Wooden Structure

17 Wood & CO 2 Wood has the unique ability to capture and store CO 2 while reducing carbon sources There are two ways to reduce CO 2 in the atmosphere: reduce emissions or carbon sources remove CO 2 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 CO 2. Every cubic metre of wood used as a substitute for other building materials reduces CO 2 emissions by an average of 1,1 ton CO 2. If this is added to the 0,9 ton of CO 2 stored in wood, we get a total of 2 tons CO 2 Source: Tackle climate change, USE WOOD

18 Why Cutting Trees is Good? forests which are left in a natural state. Younger trees, in vigorous growth, absorb more CO 2 than mature trees, which will eventually die and rot, returning their store of CO 2 to the atmosphere, while most of the CO 2 of the trees harvested from a managed forest continues to be stored throughout the life of the resulting wood product. vs InnoVentum always procures wood grown in sustainably managed forests.

19 Carbon Impact of Wood compared to Steel 2 emissions, while timber required for InnoVentum tower construction reduces CO 2 impact Source: Tackle climate change, USE WOOD

20 CO 2 balance of the Giraffe 2.0 Giraffe 2.0: - Use of wood contribution, offsetting kg of CO 2 - Use of steel components, carbon footprint: 40 kg of CO 2 CO 2 balance kg + 40 kg = - 4,660 kg Considerations: 1m 3 of wood replacing steel offsets 1500 kg of CO 2 (incl. transportation and processing of wood) 582 kg CO 2 is emitted per ton of steel manufactured Density of steel: 7850 kg/m 3-4,6 tons CO 2

21 Conclusion: Giraffe more than carbon neutral
