1. The document discusses various green infrastructure solutions including green roofs, vertical greenery, cool roofs, and water retention systems for public parks. 2. Lightweight extensive green roof systems can be installed on slopes as low as 3 degrees and weigh as little as 35-40 kg/m2 when fully saturated. They provide benefits like reducing the urban heat island effect and improving insulation. 3. Vertical greenery systems can be installed on walls or fences and provide benefits like cooling, insulation, dust absorption, and aesthetic improvements. They have been shown to reduce temperatures by over 7°C.

2. Cities of the future
1. Greenbuildings with lightweight system
2. Parking Decks (complete solution from waterproofing)
3. Vertical Greenery (easy lightweight system)
4. Anti heat-flux Roofs (new)
5. Public Parks : Water retention system for
irrigated fields-save up 40-60% water

3. Urban Heat Island Effect up to +3°C

5. What is the substrate?
A unique hydrophilic material that
is transforming the construction of
green roofs, vertical walls and soft
urban landscapes.
Due to the physical, internal
structure of VYDRO® substrate,
water molecules can easily enter
its cells but cannot easily exit it.
This means that water is stored in
the VYDRO® matrix, where it can
be readily accessed by plant roots.

9. 2.Parking decks

10. Parking decks :
• water proofing with drain layer
• terraces and ways on top of it
•Drain sheet resistant up to 30 tonnes/m²

Reinforced grass

11. Parking decks
• On the water proofing a root-barrier
and drain sheet has been placed.

14. 2.Parking decks: private gardens and parking places on
underground parking 3000m²

15. 3. Vertical greenery /Living walls
Our living walls are constructed that
provide an additional growing medium
between a geotextile and a coccus-layer
into which vegetation can actually be
planted,
Living walls provide environmental benefit
in the form of thermal insulation , cooling
benefit to the building, and noise
attenuation. Additionally it helps to absorb
health- damaging fine dust ,

16. 3.vertical walls
Vertical gardens on external fences
providing aesthetic benefits.

27. 4.Cooling roofs=anti-heatflux roofs
Cool roofs are a form of roof where the
materials used are deliberately selected
for their high solar absorption and high
thermal performances. They absorb,
and consequently store, less solar
energy during the day and thus are not
major emitters of heat into the urban
atmosphere at night,

29. 5. Public Parks/Residential gardens –
save up 50-60% water
Step 1
Level the base gound
Step 2
Unroll the Urbanscape roll
and cut it off in a way that it
will fully cover entire area.

30. Residential areas – easy set up
Step 3
Cover Urbanscape roll with
selected amount of soil cover an
level the ground
Step 4
Unroll grass mat or seed a gras
on your own.

32. Abu Dhabi – evaluation of different plant species
Controlled water stress on plants. The water
savings of at least 25% are easily achieved
and the plants performance is improved.

33. Searching for
• Planning by Goverment of more implantation of
greenroofs in cities for better climate, cooling roofs
for saving energy to cool down buildings
• Coorporation with local university to evaluate
monitoring of water by shutdown watersupply in
public parks/ev.using treated grey water
• Offering full support , training for landscapers,
contractors and architects
• Long term vision
