 A buildings Designed, Constructed and operated
with an eye to how they interact with our planet’s
ecosystem By:
1- Reserving and using sustainable energy.
2-Maintain environmental recourses mainly
water resources.
3- Lower the impact of urbanization on the
environment.

sufficient indoor air quality and sunlight.

4. Why thinking
about Green
Buildings?

9. Green Building & Owner
 Generally Green Building
may have a higher initial
coast than conventional
buildings
 Although the following can
be an assets that
encourages the building
owners:

11. Saudi Green Building
Council established in
2009
(SGBC) is a Non-Profit-Organization and a chapter of King
Saud University for scientific committees; established in 2009,
under the Saudi Society for Agricultural Sciences decree
number 6031 dated 28/3/2010 funded by an interest group of
professionals and academics in the fields of engineering
construction and environmental sciences.
SGBC accredited by the World Green Building Council
exclusively in Saudi Arabia. SGBC organized and participated
in several national, international, workshops, conferences and
activities related to Green Buildings industry.
SGBC's goal is to promote and facilitate awareness of
sustainable building practices and knowledge. In addition
preserve our urban identity, environment through creativity
and innovation for the Kingdom of Saudi Arabia.

Green Buildings … ?

14. Projects Cases
Goldman Sachs' 30 Hudson Street
 Location: Jersey City, NJ
 Building type(s):Commercial office
 New construction
 1,560,000 sq. feet (145,000 sq. meters)
 Project scope: 42-story building
 Urban setting
 Completed April 2004
 Rating: U.S. Green Building Council
LEED-NC, v.2/v.2.1--Level: Certified

15. Project Savings
Goldman Sachs' 30 Hudson Street
 The project's light-colored pavement
reduces its contribution to the urban
heat-island effect, and its minimal
exterior lighting reduces light pollution.
 A storm water collection and retention
system provides site irrigation and
cooling-tower makeup water. Combined
with low-flow fixtures, these strategies
save about 4.2 million gallons of water
per year.
 More than 60% of all wood used for the
project, and 100% of the interior wood,
was certified to Forest Stewardship
Council standards. All of the regularly
occupied spaces have access to daylight
and views to the outdoors. The building
also features educational signage that
explains the building's green attributes.

16. Projects Cases
1400 Fifth Avenue Residential Building
 Location: New York, NY
 Building type(s):
Commercial office,
Restaurant, Retail, Multi-unit
residential, Assembly
 New construction
 225,000 sq. feet (20,900 sq.
meters)
 Project scope: 8-story
building
 Urban setting
 Anticipated completion date:
March 2005

17. Project Savings
1400 Fifth Avenue Residential Building
 Environmental Aspects
 a ground-source heat pump makes
a significant contribution to
minimizing the consumption of
fossil fuels
 Ground source heat pumps use a
buried ground loop which transfers
heat from the ground into a building
to provide space heating and, in
some cases, to pre-heat domestic
hot water. As well as ground source
heat pumps, air source and water
source heat pumps are also
available.

18. Project Savings
1400 Fifth Avenue
Residential Building
 The building's close proximity to public transportation,
 the presence of bicycle storage areas, the networked living units complete with
(low-cost) broadband access, and the fully equipped onsite business center limit
environmental impacts related to transportation.
 Both structural components, such as steel joists, and finished surfaces, such as
carpeting, include recycled content where feasible.
 FSC-(Forest Stewards Council) certified cabinets and bamboo flooring reduce
the project's damage to forests.
 high-efficiency air filters assist in maintaining healthy indoor spaces.
 Variable-frequency drives on pumps,,
 day lighting, and efficient electric lighting reduce electricity consumption.
 Low-flow toilets and faucets conserve water, and a
 parking area "paved" with a porous, sod-covered matrix allows storm water to
infiltrate the soil.

19. How to Officially State a Building to Be
Recognized As a Green Building?
 In 1999 U.S Green Building
Council introduced the LEED rating
system
(Leadership in Energy and
Environmental Design)

20. What was LEED Meant For?
 It is a internationally accepted bench mark
For the : - Design
- Construction
-Operation
Of a high performance green building.

21. LEED Certificate is Possible
 Leed Certificate process is not easy process on the other hand The
LEED Rating System is flexible, not a ‘one-sized fits all’ approach
 There are a few prerequisites all projects must meet in the Rating
System, and beyond that project teams can choose which credits to
pursue based on their environmental and performance goals as long
as they meet the minimum threshold for certification
 It is not only about design.
 It needs cooperative and coordinated work between all project team
parties including:
- Owner.
- Design Team.
- Construction Team , Project & Site management.
- Commissioning Authority if provided.
- Operation, Maintenance & Measurement team.

22. LEED Points & Level:

61. Lakes Park Office Complex
 To reduce heat gain from
Florida’s harsh sun, there
are no windows on the east
and west sides of the office
building.
 Windows on the south side
of the building are shaded
by a roof overhang.
 The extensive use of
insulated, double-pane,
impact-resistant windows on
the north side brings in
natural light.

62.  The project uses day lighting
combined with daylight
sensors that automatically
adjust when artificial lighting
is not needed.
 Fluorescent lights
supplement the natural
lighting and gradually
brighten when clouds block
the sun.
Lakes Park Office Complex

63.  While moisture can create
problems for buildings Florida,
which can sometimes receive
an average of 54 inches of
rainfall in a year, gutters and
downspouts channel the rain
from the roof into a 28,000-
gallon underground cistern.
 Filters remove debris from the
stored rainwater. The collected
water is used to flush the low-
flow toilets and irrigate the
drought-tolerant landscaping.
Lakes Park Office Complex

64.  Instead of traditionally
dumping the heat to the
outside air, a more
efficient geothermal air-
conditioning system is
used that pumps cool
groundwater through a
heat exchanger to cool
the building
Lakes Park Office Complex

65.  The project also features a small-
scale photovoltaic sys-tem that
converts sunlight striking the roof
into electricity.
 Nontoxic paints, floorings,
composite woods, adhesives,
sealants, and other materials were
chosen to promote a healthier
indoor air quality.
 The buildings’ exterior walls, made
from pre cast panels of lightweight
autoclaved aerated concrete, are
full of air pockets that provide better
insulation. The buildings’ insulated
rating is more than double what is
used in standard construction.
