4. GREEN BUILDING
• The ‘GREEN BUILDING’ concept is gaining
importance in various countries. It refers to a
structure and using process that is
environmentally responsible and resource
efficient throughout a building’s life cycle.
• These are buildings that ensure efficient use of
resources and minimized waste at every stage
during the construction and operation of the
building, resulting in low costs.

5. GREEN BUILDING
• Green building also known as sustainable or high
performance building increases the efficiency
with which buildings and their sites use and
harvest energy, water, and materials, with
minimum impact on environment.
• Hence a Green Building is the one which uses
less water, optimizes energy efficiency,
conserves natural resources, generates less
waste and provides healthier space to occupants
as compared to conventional buildings.

6. GREEN BUILDING CAN REDUCE

7. • Green building (also known as green construction or
sustainable building) refers to a structure and using
process that is environmentally responsible and
resource-efficient throughout a building's life-cycle: from
Siting to Design, Construction, Operation, Maintenance,
Renovation, and Demolition.
• Green building brings together a vast array of practices
and techniques to reduce and ultimately eliminate the
impacts of buildings on the environment and human
health.
• It emphasizes on taking advantage of renewable
resources, e.g., using sunlight through passive
solar, active solar, and photovoltic techniques and using
plants and trees through green roofs, rain gardens, and
for reduction of rainwater runoff.
WHAT IS GREEN BUILDING?

8. • Maximize use of materials from sustainable
sources.
• Reduce overall energy use and maximize potential
for renewable energy supply and use.
• Minimize waste and maximize reuse and recycling
of materials both during construction and operation.
• Conserve water resources, enhance water quality,
incorporate water sensitive design and minimize
vulnerability to flooding.
• Minimize polluting emissions to water, air and soil
and minimize noise and light pollution.
OBJECTIVES

9. ELEMENTS OF GREEN BUILDING
• Resource/material efficiency
• Energy efficiency
• Water efficiency
• Waste management
• Indoor air quality
• Structure design efficiency

10. • Recycled Content. Products with identifiable recycled
content, including post-industrial/by products content
with a preference for post consumer content.
RESOURCE/MATERIALS EFFICIENCY

11. • Resource efficient manufacturing process. Products
manufactured with resource-efficient processes including
reducing energy consumption, minimizing waste
(recycled, recyclable and or source reduced product
packaging) and reducing greenhouse gases.
RESOURCE/MATERIALS EFFICIENCY

12. • Locally available. Building materials, components, and
systems found locally or regionally saving energy and
resources in transportation to the project site.
RESOURCE/MATERIALS EFFICIENCY

13. • Durable. Materials that are longer lasting or are
comparable to conventional products with long life
expectancies.
RESOURCE/MATERIALS EFFICIENCY

14. • Depending upon project-specific goals, an
assessment of green materials may involve an
evaluation of one or more of the criteria listed
below:-
– Resource efficiency
– Indoor air quality
– Energy efficiency
– Water conservation
– Affordability
RESOURCE/MATERIALS EFFICIENCY

15. ENERGY EFFICIENCY

16. ENERGY EFFICIENCY
• Better Design. Energy use can be reduced through
“No Costs” design measures that keep buildings
naturally cool in the summer and warm in the winter.
Warmer summers increase the demand for air
conditioning, which increases energy consumption,
but careful building design can prevent or reduce
the need for air conditioning through insulation and
natural ventilation.

17. ENERGY EFFICIENCY
• Renewable Energy. Reduction in the use of fossil
fuels can also be aided by incorporating renewable
energy sources like wind, solar, hydropower. By
combining energy efficiency, passive solar design
and sustainable energy supply it is now possible to
design new developments with net zero carbon
emissions.

18. ENERGY EFFICIENCY
• Solar Energy. Maximizing solar gain in winter with
large glazed areas, and a roof overhang to provide
shade in summer. Use solar water heater to cut
heating costs.

19. ENERGY EFFICIENCY
• Energy Efficient Appliances. Can perform
more with the same quantum of energy.

20. ENERGY EFFICIENCY
• Super Insulation. Good insulation of walls, roofs
and floors from renewable materials, double glazed
widows to effectively control flux of heat energy.

21. ENERGY EFFICIENCY
• Natural/Artificial Lighting. Maximizing use of
natural day lighting , skylights and high energy
efficient luminaries like LEDs.

22. ENERGY EFFICIENCY
• Building Energy Management Systems (BEMS)
to control and optimize lighting, heating and
ventilation.

23. WATER EFFICIENCY
• Reducing water consumption and protecting water
quality are key objectives in sustainable building. To the
maximum extent, facilities should increase their
dependence on water that is collected, used, purified,
and reused on-site. The protection and conservation of
water throughout the life of a building may be
accomplished by designing for dual plumbing that
recycles water in toilet flushing.

24. WATER EFFICIENCY
• Waste-water may be minimized by utilizing water
conserving fixtures such as ultra-low flush toilets, aerator
and low-flow shower heads. Point of use water
treatment and heating improves both water quality and
energy efficiency while reducing the amount of water in
circulation.

25. WATER EFFICIENCY
• Reducing potable water demand through rainwater
harvesting.

26. WATER EFFICIENCY
• Replicating natural drainage patterns, including the
recharge of groundwater so that base flows are
maintained.

27. WATER EFFICIENCY
• Use of permeable / porous pavement to enhance
percolation.

28. WASTE MANAGEMENT
• Minimise waste and maximise reuse and recycling both
during construction and after occupation.
• Demolition waste is produced in huge quantities,
maximise its reuse in building & minimize landfill volume.

29. WASTE MANAGEMENT
• 70%-90% of collected household waste is recyclable or
compostable, however over 80% of this waste goes to
landfill.

30. WASTE MANAGEMENT
• Providing on-site solutions such as compost bins to
reduce matter going to landfills.
• To reduce the impact on wells or water treatment plants,
several options exist. "Greywater", wastewater from
sources such as dishwashing or washing machines, can
be used for subsurface irrigation, or if treated, for non-
potable purposes, e.g., to flush toilets and wash cars.

31. IN DOOR AIR QUALITY
• Indoor Air Quality seeks to reduce volatile organic
compounds (VOCs), and other air impurities. Buildings
rely on a properly designed ventilation system
(passively/naturally- or mechanically-powered) to provide
adequate ventilation of cleaner air from outdoors or re-
circulated filtered air.

32. IN DOOR AIR QUALITY
• Minimize polluting emissions to water, air and soil.
• Minimized Pollution of all kinds during construction
phase.
• Minimize noise pollution within the building and from
external sources.
• Light pollution be minimized in and around the building.

33. IN DOOR AIR QUALITY
• Materials. Materials be specified to ensure low
environmental impact and to maintain good internal air
quality.

34. IN DOOR AIR QUALITY
• Moisture resistant. Products and systems that resist
moisture or inhibit the growth of biological contaminants
in buildings.

35. IN DOOR AIR QUALITY
• Systems or equipment. Products that promote healthy
IAQ by identifying indoor air pollutants or enhancing the
air quality.

36. STRUCTURE DESIGN EFFICIENCY
• The foundation of any construction project is rooted in
the Concept and Design stages. The concept stage is
one of the major steps in a project life cycle, as it has the
largest impact on cost and performance.

37. STRUCTURE DESIGN EFFICIENCY
• In designing environmentally optimal buildings, the
objective is to minimize the total environmental
impact associated with ALL LIFE-CYCLE stages of
the building project. However, building as a process is
not as streamlined as an industrial process, and varies
from one building to the other, never repeating itself
identically. In addition, buildings are much more complex
products, composed of a multitude of materials and
components each constituting various design variables
to be decided at the design stage.

38. STRUCTURE DESIGN EFFICIENCY
• A variation of every design variable may affect the
environment during all the building's relevant life-cycle
stages.
• There are design steps which may not cost but
appreciably reduce construction and maintenance costs.

39. STRUCTURE DESIGN EFFICIENCY
• No matter how sustainable a building may have been in
its design and construction, it can only remain so if it is
operated responsibly and maintained properly.
• Ensuring operations and maintenance(O&M) personnel
are part of the project's planning and development
process will help retain the same green criteria designed
at the onset of the project building's life. The addition of
new green technologies also falls on the O&M staff.

40. GREEN BUILDING CERTIFICATIONS

41. GREEN BUILDING CERTIFICATIONS
• Why Certification. Some of the benefits of using
independent environmental assessment methods to rate
new buildings and developments are:-
– Assessment as per International Standards.
– Demonstrating sustainability credentials to planning
authorities.
– Demonstrating environmental credentials to investors
to help minimize investment risk and increase the
appeal to investors.
– Demonstrating superior environmental design to
customers including reduced running costs, health,
comfort and flexibility of internal environments, and
access to local amenities.

42. GREEN BUILDING CERTIFICATIONS
• Common certifications:-
– Building Research Establishment’s Environmental
Assessment Method (BREEAM) – UK based, establish
in 1990.
– Ecohomes – BREEM based residential development.
– Leadership in Energy and Environmental Design
(LEED) – established in 1993, most widely used.
– Energy Star – more emphasis on materials.
– Pakistan Green Building Council – no certification as yet

43. GREEN BUILDING CERTIFICATIONS
• LEED – US based
• LEED or Leadership in
Energy & Environmental
Design, is a green
building certification
program that recognizes
best-in-class building
strategies and practices.

44. GREEN BUILDING CERTIFICATIONS
• To receive LEED
certification, building
projects satisfy
prerequisites criteria
and earn points to
achieve different levels
of certification.

45. GREEN BUILDING CERTIFICATIONS
There are five rating systems that address multiple project types:-
Four levels of certification:-

46. GREEN BUILDING CERTIFICATIONS
• LEED Beta Version 4 is under process of
implementation.

47. GREEN BUILDING CERTIFICATIONS
• BREEAM and Ecohomes
are managed by the Building
Research Establishment UK
and these are both an
environmental assessment
tool and an accreditation
scheme.

48. GREEN BUILDING CERTIFICATIONS
• BREEAM can be applied to
offices, retail developments
and industrial buildings and
Ecohomes is the version of
BREEAM for residential
development. A BREEAM for
schools is in development.
• These assessments cover
energy, water, materials,
transport, pollution, ecology
and health and give a rating of
‘pass’, ‘good’, ‘very good’ or
‘excellent’. A checklist can be
used to predict a rating from
plans and specifications.

49. GREEN BUILDING CERTIFICATIONS
• Pakistan GBC was
established in December 2012
and working under umbrella of
World Green Building Council
which is a union of 98 national
Green Building Councils from
around the world, making it the
largest international
organization influencing the
green building marketplace.

50. GREEN BUILDING CERTIFICATIONS
The organization is in early stages and primarily
educating on green building technology in Pakistan.
• Standard for certification of Green Buildings and
Communities in Pakistan is yet to be established.
• Number of buildings certified by Pakistan GBC are
none, however Pebbles Housing in Sheikhupura is its
first ever project in hand.

front and analyzes their implications for green
buildings, highlighting examples of “best in
class” buildings employing green and intelligent
technologies. These buildings are dynamic
environments that respond to their occupants’
changing needs and lifestyles.
• This research provided a direction to educate
and influence end-users, building owners,
architects, and contractors that green technology
will provide a tangible and significant return on
investment along with other economic benefits

75. TITANIUN DIOXIDE GLASS
• Light energized, photocatalytic TiO2 is a safe,
non-toxic, anti-oxidant that produces hydroxyl
radicals (OH-) that are remarkably effective in
rapidly decomposing organic matter, including
bacteria, fungi, odors and nicotine. This
chemical process converts organic matter into
the harmless elements of water and carbon
dioxide, which are then released into the air.

 It is the concept of sustainable building and has largest
impact on cost and performance.
 It aims to minimize the enviornmment impact associated
with all life-cycles.
• ENERGY EFFICIENCY:
 The layout of the construction can be strategised so that
natural light pours for additional warmth.
 Shading the roof with trees offers an eco-friendly
alternative to air conditioning.
 An example of this are solar power panels,not only they
provide lightening but they are also a useful energy
source.

79. • WATER EFFICIENCY:
 To minimize water consumption one should aim to
use the water which has been collected, used, purified
and reused.

80. • MATERIAL EFFICIENCY:
 Materials should be use that can be recycled and can
generate surplus amount of energy.
• WASTE AND REDUCTION:
 It is probable to reuse resources.
 What may be waste to us may have another benefit to
something else.

have tremendous effect on our enviornment and
natural resources.
• Green Building is different from the other buildings
because it use a minimum amount of nonrenewable
energy, produce minimal pollution, increases the
comfort, health and safety of the people who work in
them.
• It also minimize the waste in construction by
recovering materials and reusing or recycling them.

89. INCREASING GREEN BUILDINGS IN
INDIA
• Today more than 1053 green buildings (as on April
2011) are being constructed all over India, of which
147 green buildings are certified and fully functional.
