Comparison of Green Open Space (m2/person)

in asian Cities1

f I G U R E . 0 1

Urban green open spaces are essential for social, economic and

environmental development of cities. despite being blessed with rich soil and mild tropical climate that supports vegetation, Jakarta’s per capita green area is only 2.3 m2, which is one of the lowest among major asian cities as shown in the graph below.

Jakarta’s green open space has alarmingly decreased over the past 50

years. This is reflected in rapidly reducing green open space targets in

the government’s masterplans from 37% (1965-85) to 14% (2005-10).

Green Open Space

Built Up Space

Masterplan Targets actual

2030Target

In accordance with the national law2, the Jakarta government has set itself

a target of achieving 30% green open space by 2030. While a part of this

will be achieved through creation of parks and green belts, a significant

increase in privately owned green open spaces is also needed. The

new green building code addresses this issue by mandating a minimum

green open area for new construction. The code also requires the use of

permeable paving materials to decrease site water run-off.

2 law 26/2007 on Spatial Planning and development, which requires each Indonesian city to allocate at least 30% of its territory to become green open space, 20% out of which must take form as public domain.

limited green open spaces for social gathering interaction and physical recreational activities.

High concentrations of buildings and hardscape such as concrete has caused an increase in Jakarta’s average temperature, resulting in increased air conditioning of buildings.

Concentration of CO2 and other pollutants has increased, causing health issues and productivity losses.

Regional ecosystems have been adversely impacted due to loss of habitat and migratory paths for birds and animals in urban areas.

Reduced area for rainfall absorption into ground, causing erosion, drop in ground aquifer levels and river flooding.

Increased open spaces on private properties for social interaction.

Reduction in average temperature due to increased vegetation.

Reduction in air pollution due to increased vegetation and decreased energy use in buildings.

Urban ecosystems will be partially restored due to increased vegetation.

Increased permeable hardscape area will increase ground water absorption and reduce run-off into rivers.

02 issues & code benefits

The following section describes some of these issues and impacts in

more detail.

Although difficult to quantify, the economic benefits of these code

requirements are expected to be huge. Similar initiatives in Australia have

shown environmental and property value cost benefits at $3.81 for every

$1.00 spent on tree planting and management.3

This phenomenon can result in a temperature rise of up to 4oC in urban

areas, and has been largely attributed to the high concentration of artificial

materials such as concrete. Trees are very efficient in controlling the

microclimate by absorbing as much as 80% of the solar radiation falling

on them, thus reducing the heat build-up on the ground. Leaves and soil

release water vapor, which upon evaporation cools the air and surface

temperatures. In contrast, concrete and other man made materials radiate

back most of the absorbed heat, thus causing concentrations of heat.

Urban heat island is the term used for concentration of higher

temperature in cities as compared to surrounding areas.

Besides temperature, urban areas can also have a greater concentration

of pollutants as compared to surrounding areas. Some studies provide

evidence that CO2 concentrations in urban areas can be 5-80 ppm above

adjacent rural areas where extensive plants are growing6.

Air pollution levels have generally followed the GDp growth trends in

Jakarta for the past decade. As shown above the concentration of pM10

(particulate matter smaller 10 microns) is much higher than the WHO Air

Quality Guideline. prolonged exposure to pM10 can cause cardiovascular

and respiratory diseases, as well as of lung cancer. The mortality in cities

with high levels of pollution exceeds that observed in relatively cleaner

cities by 15-20%.8

As seen above, measured maximum air temperature in all regions of

Jakarta have been rising, in some cases by as much as 2oC in less than

10 years. Also interesting to note is the big temperature difference

between Jakarta and Bogor. Despite being close to Jakarta, Bogor’s

maximum temperatures were lower by about 3oC mainly due to its

higher green cover.

As the ambient air temperature in Jakarta has increased, the desired

indoor air temperature has generally gone down, thus drastically

increasing the air conditioning load in its buildings.

Increasing the green open spaces in new building sites will play an

important role in dissipating the Jakarta’s heat island effect, which

will decrease its building cooling requirements. Energy simulation for

six typical building types in Jakarta have shown that 2%-11% of the

total energy consumption can be cut down by just 1oC reduction of

temperature difference between inside and outside.

Introduction of additional trees has been shown to reduce air pollution

and its adverse health impacts. In United Kingdom, presence of trees has

been estimated to save between five and seven deaths and between four

and six hospital admissions per year due to reduced pollution of sulfur

dioxide and pM109. Modeling for London estimates that 25% tree cover

removes 90.4 metric tons of pM10 pollution per year, which equates to a

reduction of two deaths and two hospital stays per year10.

Numerous studies showing health benefits of having gardens in health

facilities have been published11. Results from one such study (presented

below) show the improvement in general perception among patients who

spend time in hospital gardens.

Development of cities causes a disruption of animal and plant habitat

and ecosystem. Some of this balance can be brought back in cities by

having parks and connected corridors. Development of modern Singapore

caused similar disruptions, resulting in the loss of 95% of the city’s

original natural forests. However, over the past 20 years, the city’s green

cover has been increased from 36% to 47%, despite a doubling of its

population. Impact of this initiative has been quite visible. About 500

new species of flora and fauna, like the green tree snail and the long-

legged fly, have been spotted again or have been seen for the first time,

including 100 species new to science.13

Green open spaces are an expression of local culture, social interaction,

recreation, and education. Building properties with sufficient green

open spaces are considered more visually appealing and can sometimes

increase the property value too.

The low proportion of green open spaces in Jakarta has increased the

rainwater run-off into the rivers. This is one of the major reasons for

flooding of rivers on an almost annual basis. High run-off also prevents

replenishment of underground aquifers, thus causing sinking of some

parts of the city. By providing sufficient green open spaces, the chances

of river flooding can be reduced and aquifer depletion can be slowed or

even reversed.

Water runoff coefficients shown in the figure above show the significant

difference in the amount of rainwater that is not typically absorbed by

hardscape (asphalt, brick etc.) and softscape (grass etc.). A reasonable

option for areas where hardscape is needed is permeable material such

as porous asphalt and concrete that allows some water to percolate

through to the ground below.

More details on the water run-off and

aquifer are found in the Water Efficiency

user guide.

A detailed list of vegetation commonly

used in urban landscape is in Appendix A.

03 design principles

this section provides some design principles for complying with the code requirements given above and also describes some best practices that exceed the requirements.

Landscape elements are usually classified as softscape or hardscape.

Softscape typically includes flowers, plants, shrubs, trees, flower beds

and similar live, horticultural elements. Hardscape in contrast, consists

of inanimate objects of a landscape such as roads, walkways, pavers,

stones, rocks, etc.

Efficient softscape includes some or all of these elements:

indigenous plant species: that do not consume too much water.

Groundcover: plants whose height is no more than 0.5 meters, which

bind the soil together and prevent soil erosion. Grass turf does not usually

provide the environmental microclimatic benefits of larger shrubs and

trees, while requiring much higher maintenance. Turf should only be used

in areas where they are required for active use, such as a playground, or

a walking area. for all other softscape areas, shrubs and trees should be

considered.

shrubs: plants with heights less than 50 cm are considered as Bushes,

whereas shrubs have a height of between 0.5-3 m. These plants often

serve as barriers to erosion and noise.

palms: these tree species from tropical climates typically have a tall,

straight, unbranched stem, with a low canopy density, thus making them

less effective in blocking and absorbing solar radiation. If at all used, palm

trees should be mixed with trees of larger canopies.

Bamboo: Similar to palms, bamboos have small canopies and therefore

cannot block much solar radiation. However, they grow fast and can act as

sound, light or pollution screens.

shade trees: are generally with a height more than 6m with a wide and

dense canopy of about 10 m width in a fully grown tree. Shade trees

should be used wherever possible to get optimum microclimatic benefits.

Zoning refers to grouping vegetation of similar water requirements for

efficient irrigation system. This provides greater efficiency in irrigation and

landscape maintenance.

Vertical garden incorporates plants on the external façade of the building.

It could be done through climbing plants with self-clinging roots growing

directly on coarse building surfaces, cascading plants in roof planters, or

through specialized vertical planter boxes.

A Singapore study, using an air temperature prediction model STEVE,

(Screening Tool for Estate Environment Evaluation), shows that air

temperature in the high density urban areas can be reduced significantly

due to use of vertical gardens.

potential benefits of Green roofs include:

• Rainwater retention: Green roofs retain rainwater, thus reducing run-

off into storm water drains

• Reduction in heat island effect: Green roofs can lower air temperature

in its surroundings through evaporation from soil and plant surfaces.

• increased biodiversity: Green roofs, along with vertical greenery can

partially restore the habitat and migratory paths for birds and insects.

Studies have shown that butterflies can go as high as 20 floors to

access green spaces.

• usable recreation area: Accessible Green roofs provide additional

usable area for recreation and relaxation, which sometimes increases

property value as well.

• Food production: Growing vegetables and herbs on green roofs and

vertical gardens can provide fresh produce to the building occupants at

low costs, even in dense urban areas. If occupants are involved in urban

farming, it can provide social benefits as well.

• Reduced cooling load: Green roofs can significantly reduce roof

surface temperatures through shading, increased surface reflectance

and evaporative cooling effect of plants. A US study showed a 21oC

reduction in maximum average temperature on the Green roof (54oC) as

compared to a conventional roof (33oC), which could reduce cooling load

from 1%-25%, depending on building characteristics24. Obviously, the

potential benefits are higher for buildings that have more area available

for green roofs.

Some of the challenges with Green roofs are:

• Higher first costs: There might be additional costs for constructing

green roofs, to account for the extra load and water proofing

requirements. In addition, there are costs for plants, soil, drainage

system etc. Green roof costs from Singapore (figure below) show an

average USD 100/m2 additional cost for continuous extensive roof and

USD 240/m2 for intensive roof.

• increased maintenance: It is estimated that around 20% of plants on

intensive green roofs and 10% of the plants on extensive green roof

need to be replaced annually. fertilising, weeding and pruning on Green

roofs need to be done on a regular basis. Modular roofs require the

most maintenance effort, due to the limited useful life of planting trays.

Therefore, maintenance tends to be a significant cost and effort for

green roofs.

• Low roof area availability: Due to the high density and land prices,

most new construction in Jakarta is high-rise. After the mechanical

equipment and water tanks are placed on the roof, typically only a

small part of the roof is available to have a green roof. More green

roof area could be made available by placing the mechanical equipment

somewhere else, and by designing the building to have terraces and

roofs at multiple levels.

more information on design and installation of Green roofs can be found in:Singapore Building Construction authority’s Rooftop Greenery Guide (http://www.skyrisegreenery.com/images/uploads/publications/A_Concise_Guide_to_Safe_Practices_for_Rooftop_Greenery.pdf)

Irrigation water consumption can be reduced through some of these

options:

automatic irrigationAutomatic irrigation uses system controllers such as rain sensors that

prevent sprinkler systems from turning on during and immediately after

rainfall, or soil moisture sensors that activate sprinklers only when soil

moisture levels drop below pre-programmed levels.

drip irrigationDrip irrigation is made up of flexible polyethylene pipe, usually installed on

the surface of the ground and covered by mulch, with small drip emitters

that are either plugged into holes punched in the tubing or molded directly

into it. Drip irrigation could be controlled by a manual or an automatic

control valve.

Direct application of water into the soil results in little runoff, no spray

drift, and consequently no wasted water or safety problems. Drip

systems are nearly 100% efficient, delivering all the water to the root

zone of the plants in an even pattern throughout the area. fewer weeds

grow in the surrounding soil as it is not irrigated. Installation costs are

comparable to (or lower than) those of a sprinkler system, and operational

water consumption cost is also lower. Drip irrigation systems should be

carefully design and maintained to prevent blockage and breakage.

alternative Water sourcesTo further reduce water consumption, alternative sources of irrigation

such as greywater, reclaimed water, and collected rainwater should be

considered.

Greywater is untreated household waste water from bath room sinks,

showers, bathtubs, and clothes washing machines, whereas reclaimed water

is waste water that has been treated to levels suitable for nonpotable uses.

Use of reclaimed water, rainwater and greywater can substantially reduce

water consumption in most buildings.

more information on high efficiency irrigation systems is available in: efficient Irrigation for Water Conservation Guideline by Queensland Water Commission, australia (http://www.dews.qld.gov.au/__data/assets/pdf_file/0020/33635/efficient-irrigation-guideline.pdf)

This issue is covered in more detail in the Water Management

and Efficiency section of the guidelines.

Efficient hardscape includes some or all these elements:

pervious (or permeable) materials allow water to percolate into the

ground. Impervious hardscapes exacerbate many environmental problems

such as heat island effect, downstream erosion, soil pollution, and water

pollution. They cause stormwater runoff to overwhelm and contaminate

municipal sewer systems, resulting in increased costs for wastewater

management and other municipal services. The results are also damaging

to the natural environment.

There are many types of pervious pavement and construction methods

available in the market to replace asphalt or solid concrete. Generic

pervious materials are listed below.

for vehicular and pedestrian pavements, pervious concrete, porous

asphalt, and permeable interlocking concrete pavement are feasible

choices.

porous asphalt and other pervious materials cost 10-40% more

than standard asphalt on a unit area basis. This is primarily from the

installation of a filter layer and porous stone bed that is usually deeper

than conventional hardscape bases. However, pervious surfaces

decrease or eliminate the need for detention ponds and significantly

reduce water run-off.

pervious concretepervious concrete is a durable, high porosity concrete that allows water

and air to pass through it. A 25 to 30 cm thick subgrade aggregate base

holds the water until it can soak into the soil.

porous asphalt pavementfast and easy to construct, these are similar to pervious concrete. Water

drains through the porous asphalt and into the stone sub-base and then

infiltrates into the soil. In contrast to pervious concrete, however, the

stone sub-base for porous asphalt is often 45 to 90 cm deep.

permeable interlocking concrete pavementpermeable Interlocking Concrete pavement (pICp) is similar to both

pervious concrete and porous asphalt in infiltration rate, but differs in

that the pavement surface is composed of concrete pavers separated by

0.3 to 1.25 cm wide joints filled with aggregate. The pavers themselves

are not pervious, but the joints between the pavers are, which accounts

for the high infiltration rates. The sub-base stone serves as a reservoir

for water that has filtered through the aggregate-filled joints.

High Reflectance Hardscape materialsHigh reflectance hardscape materials are paving materials with high solar

reflectance (albedo), such as light colored concrete. These materials absorb

less solar radiation, thus remaining cooler. Since they do not absorb much

heat, they can be used for reducing urban heat island effect.
