3. 1) Sustainability is derived from
the Latin word sustinere (to
“maintain", “ to support", or
“to endure”)
2) “sustainable development is
development that meets the needs
of the present without
compromising the ability of future
generations to meet their own
needs.” )
3) For humans, sustainability is the
long-term maintenance of well
being, which has environmental,
economic, and social dimensions,
and encompasses the concept
of stewardship, the responsible
management of resource use.

6. DEFINITION OF GREEN DESIGN
1) A Green building focuses on increasing the efficiency of resource use – energy, water,
and materials – while reducing building impact on human health and the
environment during the building’s lifecycle, through better sitting, design,
construction, operation, maintenance, and removal.
2) Green Buildings should be designed and operated to reduce the overall impact of the
built environment on its surroundings.
Green buildings are designed to save energy and
resources, recycle materials and minimise the
emission of toxic substances throughout its life cycle
Green buildings harmonise with the local climate,
traditions, culture and the surrounding environment.
Green buildings make efficient use of resources, have
significant operational savings and increases
workplace productivity.
7. 1) Energy Efficiency (EE)
Improve energy consumption by
optimising building orientation,
minimizing solar heat gain through the
building envelope, harvesting natural
lighting, adopting the best practices in
building services including use of
renewable energy, regular maintenance.
2) Indoor Environment Quality (EQ)
Achieve good quality performance in
indoor air quality, acoustics, visual and
thermal comfort. These will involve the use
of low volatile organic compound
materials, application of quality air
filtration, proper control of air
temperature, movement and humidity.
8. 3) Sustainable Site Planning & Management (SM)
Selecting appropriate sites with planned access to public transportation, community
services, open spaces and landscaping. Implementing proper construction
management, storm water management and reducing the strain on existing
infrastructure capacity.
4) Materials & Resources (MR)
Promote the use of environment-friendly materials sourced from sustainable
sources and recycling. Implement proper construction waste management with
storage, collection and re-use of recyclables and construction formwork and waste.
5) Water Efficiency (WE)
Rainwater harvesting, water recycling and water-saving fittings.
6) Innovation (IN)
Innovative design and initiatives that meet the objectives of the GBI.

10. GREEN DESIGN
Passive design Active design
•Building orientation, location
• Insulation and Shading
•Day lighting
•Natural ventilation
•Solar panel
• green roof
•Green wall and façade
•Rainwater harvesting
•Green material
11. The key elements of passive design are:
building location and orientation on the site;
building layout; window design; insulation
(including window insulation); thermal mass;
shading; and ventilation. Each of these
elements works with others to achieve
comfortable temperatures and good indoor air
quality.
It responds to local climate and site
conditions to maximise building users’
comfort and health while minimising energy
use.
It costs little or nothing to incorporate passive
design into a new building. The benefits are
greatest when passive design principles are
incorporated into the entire design and build
process, from site selection onwards.
12. 1) Building orientation
For maximum solar gain, a building will
be located, oriented and designed to
maximise window area facing north (or
within 20 degrees of north) – for
example, a shallow east-west floor
plan. However, this will depend on the
site’s shape, orientation and
topography. For example, an east-west
floor plan will not be possible on a
narrow north-south site
13. 2) Insulation
Insulation acts as a barrier to heat flow,
reducing heat loss in winter to keep the
house warm or reducing heat gain in
summer to keep the house cool.
Insulation is needed in the ceiling, walls
and floor.
14. 1) Shading should be designed to
take into account the sun's path-
low and high angle
2) The sun’s high angle means that it
will not enter these windows during
the summer months if shaded by
eaves or external shades.

15. Elements of shading are such as:
• Eaves - Eaves or other fixed overhangs
are the simplest way to provide
protection against solar gain.
• Awnings- should be light in colour to
deflect more heat. Retractable
awnings will admit sunlight when in
retracted position
17. Elements of shading are such as:
• louvers - The louver panels may
be fixed blade or operable. They
provide an excellent solution for
low angle morning and evening
sun as they can be moved away
to admit light when not required.
• Verandas - Deep verandahs are
particularly good for shading east
and west facing elevations
although they will still admit very
low angle sun.
18. • Pergolas - Pergolas
covered with deciduous
vines provide very good
seasonal shading.
• trees and shrubs.- able to
filter 60% of heat
19. Ventilating features
When designing a natural
ventilation system, the long
façade of the building should be
facing the prevailing wind
direction, with doors and
opening windows providing the
ventilation openings.
Ensure that openings (inlet and
outlet) are:
•not obstructed
•the same size
•able to control the flow
•located in opposing pressure
zones to increase the potential
air flow.
20. Other ventilating features include:
1) maintaining a vertical distance
between two openings to
create a stack effect, i.e. hot air
rising and thereby enhancing
air flow
2) maximising air flow by
designing open plan spaces
3) maximising air flow by having
openings at different levels or
near the ceiling on opposite
sides of the space
4) using architectural and
landscape features to direct
and control air flow - for
example, using casement
sashes on the windward façade
as these can be more efficient
than other types of, and
including opening windows on
the leeward face
21. 1) Daylight should be used as much
as possible to light a home, both for
energy efficiency and for the health
and comfort of occupants.
2) Principles for utilising natural light
include:
• Use diffused light rather than direct
sunlight, which requires careful placement
and sizing of windows
• Avoid too many glazing
•using roof-lights for top lighting –
insulated glazing units (IGUs) must be
used for roof glazing to minimise heat
loss
22. •The higher the window head, the deeper
the daylight will penetrate into the interior. A
window will produce useful illumination to a
depth of approximately 1.5 times the window
head height. Therefore, increasing the height
of the window head can increase the depth
of light penetration up to two times or more.
23. Panels (arrays of photvoltaic cells) make
use of renewable energy from the sun,
and are a clean and environmentally
sound means of collecting solar energy.
third generation solar cells are advanced
thin-film cells. They produce high-
efficiency conversion at low cost.
24. Solar Ivy is a modular and customizable
photovoltaic product with a wide range of
applications.
The “leaf” is roughly the size of a cantaloupe
with a thin-film photovoltaic panel adhered
to it
To set up a Solar Ivy system, first the building
interface is attached and a steel wire mesh is
installed. The steel mesh can bend, curve or
stretch to match any contour, and the leaves
can be positioned for varying densities
depending on window placement and
exterior shading. Individual leaves can be
replaced as technology improves or if one
becomes damaged. The system provides
renewable energy for the building using the
sun and breezes while also serving as a shade
screen that minimizes solar heat gain.
25. Masdar will employ a variety of renewable power
resources. Among the first construction projects
will be a 40 to 60 megawatt solar power plant, built
by the German firm which will supply power for all
other construction activity. This will later be
followed by a larger facility, and additional solar
panels will be placed on rooftops to provide
supplemental solar energy totalling 130
megawatts. Wind farm will be established outside
the city's perimeter capable of producing up to 20
megawatts, and the city intends to
utilise geothermal energy as well. In addition,
Masdar plans to host the world's largest hydrogen
power plant

clothes, watering the garden and washing cars;.
Rainwater harvesting is the accumulating and
storing of rainwater for reuse before it reaches
the aquifer. It has been used to provide , water
for livestock, water for irrigation, as well as other
typical uses.

Benefits associated to a green wall
• Provides sound insulation.
• Filters air particulates to improve air quality.
• Reduces the Heat Island Effect.
• Moderates a building's internal temperature via external
shading.
• Creates a microclimate, which will help to alter the climate
of a city as a whole.
• Helps a building retain heat otherwise lost to convection.
• Provides storm water management, absorbing 45-75% of
rainfall.
• Serves as a natural water filter and water temperature
moderator.
• Provides biodiversity and a natural animal habitat
Living wall or green wall is either
free-standing or part of a building with
some sort of vegetation

What is green facades and living wall ????????????
Green façades feature plants that are rooted into the ground, while living walls are built from
pre-vegetated panels or integrated fabric systems.

The Bosco Verticale is a system that
optimizes, recuperates, and produces
energy. Covered in plant life, the
building aids in balancing
the microclimate and in filtering the
dust particles contained in the urban
environment .The diversity of the
plants and their characteristics
produce humidity, absorb CO2 and
dust particles, producing oxygen and
protect the building from radiation
and acoustic pollution. This not only
improves the quality of living spaces,
but gives way to dramatic energy
savings year round.
Each apartment in the building will
have a balcony planted with trees
that are able to respond to the city’s
weather — shade will be
provided within the summer, while
also filtering city pollution; and in the
winter the bare trees will allow
sunlight to permeate through the
spaces.
