new innovation which can help to create you roof top garden and terrace garden beautiful and most attractive

2. Why A Rooftop Garden?
 Reduce the “urban heat island effect”
 Reduce amount of greenhouse gas
 Grow your own vegetables and fruits
 Reduce and clean storm water runoff
 Reduce energy consumption
 A thing of beauty
 Give back to your environment
 A boon for your health

3. Roof Garden
 A roof garden is any garden on the roof of a
building.
 Besides the decorative benefit, roof plantings
may provide food, temperature control,
hydrological benefits.
 Also provides architectural enhancement,
habitats or corridors for wildlife, recreational
opportunities, and in large scale it may even
have ecological benefits.

6. TYPES OF ROOF GARDEN
CHARACTERISTIC EXTENSIVE INTENSIVE
Growing Medium Depth 150mm or less >150mm
Accessibility Often inaccessible Usually accessible
Fully saturated weight Low
48.8-170kg/m2
High
244-1500 kg/m2
Plant diversity Low Greatest
Cost Low High
Maintenance Minimal Varies, but is generally high

7. Extensive Roof Garden
1. SHALLOW ( ULTRA EXTENSIVE):
 Shallow Roof Garden System (growth
media depth 2.5” to 4") is ideally suited
for areas likely to receive little
maintenance.
 Recommended plants include sedums,
herbs and grasses.
 The anticipated weight above the membrane assembly is generally between 4.8 and 6
pounds per square foot, per inch of system depth, in a saturated state

8. 2. Medium Depth Roof Garden System
 Medium Depth Roof Garden System (growth
media depth of 5" to 8") includes plants such as
sedums, herbs, grasses and other vegetation,
which can grow in this depth of media.
 Un-irrigated systems can be provided without
difficulty; however, drip, mist or spray irrigation
systems may be required to support more diverse
plant types or for installations in semi-arid climates.
 The anticipated saturated weight above the membrane assembly is less than 50 pounds per square
foot.

9. Intensive Roof Garden System
 The intensive green roof uses planting
mediums that have greater depth than the
extensive green roof.
 Deeper soil allows intensive roofs to
accommodate large plants and dramatic
plant groupings. Another term for these
green roofs is “rooftop garden”.
 The planting medium in intensive green
roofs starts at 6 inches.

10. Conti.
 This system typically requires a structural concrete roof deck to support the larger dead load.
 An irrigation system should be utilized in these
assemblies.
 The anticipated weight above the membrane
assembly is generally greater than 50 pounds
per square foot.

12. Essentials roof top gardening
Now a days pot garden and kitchen garden on roof totally
replaced and posed the usage of new innovative concepts and
techniques :-
A. Green roof: A green roof or living roof is a roof of a building
that is partially or completely covered with vegetation and a
growing medium, planted over a water proofing membrane.
There are three types of green roofs.
B. Drainage cells : The drainage cell in combination with a Non -
biodegradable eco friendly plastic acts as the protection layer
for the underlying Waterproof membrane and provides
ventilation for concrete slab.

13. C. Moisture retention mat: It is composed of high-quality,
non-deteriorating, polypropylene fibers retain moisture in
roof gardens and available in rolls
 Its a very handy innovative concept for high temperature
location.
D. Water proof technique: It is an useful innovation to restrict
the moisture of the excess water and rain water in the roof
and protect wall from intaglio.

14. Water holding technique and storm water
management
 We have to adopt few innovative techniques to collect
storm water runoff and rainfall for storage in the soil profile
or other storage areas so that it can be used later for
productive purposes. That are as follows:-
A. Hydrogel polymers or Super Absorbent Polymers :- It has a
water uptake potential as high as 100,000% of its own
weight in a short period of time by osmosis and form
granules in soil to enhance soil properties.

15. Conti.
 SAPs are generally white sugar-like hygroscopic
materials that swell in water to form a clear gel made
of separate individual particles and can retain moisture
even under pressure without risk of conflagration or
rupturing/blasting.
 Using of hydrogel in roof garden for water
conservation and moisture retention would be a useful
innovation.

16. A. Protection fabric:
B. Root barrier: The most common root barriers used are thin
polyethylene sheets, laid over the waterproofing
membrane.
 Thicker, welded root barriers will be needed for green
roofs involving trees, bamboo or other vigorous, spreading
grasses.
 The root barrier restricts the spread and penetration of root
in the floor and wall. It would be a useful innovation
especially for terrace gardening.
Innovative approaches

17. C. Acoustic insulators: Plants have many known benefits to
their environs and the people in them. Noise reduction is
one of those less-known benefits of plants.
 Plants are used in many applications to reduce noise. One
major example is plantings along freeways to help reduce
the amount of noise distributed to adjacent communities.
Plants can also greatly reduce unwanted noise inside
buildings.

18. D. Recycle materials for decking : Waste wood pieces and
plastic can be effectively utilized as a deck on for any
arrangement along with plants as a hardscape element.
E. Fire resistant graphite technology: By this innovation, the
supply of oxygen will cut off during any fire and the spread
will be arrested.
 Sprinkler systems could provide the rapid extinguishment of
almost any fire that would occur on the roof garden.
Horticulturalists support the idea of watering the roof; it’s
possible that a dual-purpose system could be developed.

19. F. Renewable energy: Solar panels and green roofs are
common sustainable options for environmentally friendly
roofs. It is some time called photo voltanic panel.
 Attachment of film photo voltaic panels saves the energy
consumption and the renewable energy generated could
be used for roof top lighting, irrigation system and
maintenance.
G. Vertical garden: Green facade (with flowering and foliage
climbers) and living walls are the new innovations in vertical
garden.
 It is boon to corporate, IT parks and shopping malls

20. H. Soilless culture and hydroponics: The use of a traditional
soil medium for growing plants will create an extra load in
roof gardens. To cope up with this issue, that scientific
soilless culture and hydroponics are one of the best and
very innovative techniques for terrace garden.
I. Skyrise gardening: It is innovative kind of garden coined
in Singapore refers to both rooftop and vertical
greenery. “garden city” to a “city-in-a-garden”.
 It is strategy aimed at extending greening skyward in the
build environments through the greening of facedes,
balcony, mid-level and top most of roof

22. Materials Needed to
Create a Rooftop
Garden
Typical materials for a rooftop garden may
include:
 Plants
 Growing containers
 Growing medium
 Decking or other material that can be walked
on and
 Seating, wildlife features, greenhouses or
composters.

29. Loading Capacity
 The load bearing capacity of a building must be known before planning a green roof, wall or
facade.
 For a green roof, wall or facade, the loads that the building structure must support include:
 Dead load – the final constructed weight of all built elements and all components associated with
the roof or wall assembly, including plants, growing substrate and any water held in the system
 Live load – the weight of people who will use the space, and of any mobile equipment that will be
used periodically on the site, for example, maintenance (live load generally applies to green roofs,
not facades or walls, however it would be appropriate on a vertical surface if a trafficable
maintenance platform was built into the system)
 Transient load – moving, rolling or short-term loads, including wind and seismic activity

30. Weight loadings for some representative climbing
species
Green facade species Weight loading (kg/m2)
Jasminum (Jasmine), Rosa (Rose) 6-12
Clematis (Clematis), Tropaeolum (Flame Nasturtium) 3-12
Vitis (Ornamental Grape), Ampelopsis (Porcelain Vine) 12-26
Lonicera (Honeysuckle), Actinidia (Kolomitka), Wisteria (Wisteria) 10-26

31. Green roof vegetation weight loadings
Green roof vegetation type Weight loading (kg/m2)
Low herbaceous (succulents and grasses) 10.2
Perennials and low shrubs up to 1.5 m 10.2-20.4
Turf 5.1
Shrubs up to 3 m 30.6
Small trees up to 6 m 40.8
Medium trees up to 10 m 61.2
Large trees up to 15 m 150

32. Drainage: Maintenance:
 Drainage can easily be installed with a stony layer,
preferably uniform in color.
 White stones reflect sunlight too strongly. Yellow or
brown stones are more in harmony with the
vegetation cover.
 Instead of little stones, polyurethane chips or foam
chips can also be used.
 Watch and determine where water flows to on your
roof and ensure those areas and drainage paths
are maintained roof is designed such to
withstand pooling of water.
 To maintain clear access to the roofing
membrane and drains for maintenance and
repair, install roof to garden in sections. This can
easily be done using containers of any height or
size, arranged in sections on roof.
 Designing rooftop garden in sections will avoid
removing the entire garden area each time the
roof needs some repair work.
 Remember to factor in the weight of each
container and its wet soil weight when
designing the garden.

33. SELECTING THE BEST PLANTS FOR ROOFTOP
GARDENS
Before making your selections, consider some of the characteristics of
your rooftop. These characteristics are:
 The size of your roof
 Whether your roof is flat or slanted
 Most important is the pattern of plants—whether you want to grow
plants on the roof floor, in pots or in raised beds
 Here is a list of some of the best plants for rooftop gardens
Kousa Dogwood

34. LavenderJapanese Wisteria
Gold Flame
Honeysuckle

35. , Blue Star JuniperBlue Fescue

36. Microclimate — The height and location of building in relation to surrounding buildings can affect the
amount of sun rooftop garden receives, as well as the exposure to wind.
 Determine the wind and sun conditions on roof and select hardy plants that can flourish under the
conditions rooftop garden provides your roof.
Soil type and amount — The type of soil and the thickness are the most important factors to consider
when selecting plants. It is better to use lightweight soils, no matter the thickness.
 These soils include perlite, peat moss, vermiculite, coconut husk fibres and some others. Due to their
lightness, these soils will add quantity without having any harmful effects on the plants’ stability.
 Thus, lighter soils are best for both intensive and extensive roof gardens.
 It would be a good idea to select plants that require the least amount of soil for their growth. For
plants having shallow roots would be best for rooftop gardens.

37. Availability of water — Watering during the summer months should be addressed in advance.
 Summer is when the garden and plants need the most attention.
The use of nutrients (fertilizer) — Most of the crops chosen should do well in the thin layer of soil they
are growing in.
 Nutrients should be replenished from time to time, so that no obvious nutrient deficiencies are
manifested in the appearance of the plants.
 Application of the TC-method (TerraCottem Soil Conditioning Technology) offers a very interesting
interesting advantage: only 50 % of the normal dosage of fertilizer has to be applied after several
months of plant growth.
