3. INTRODUCTION
• WHAT IS SUSTAINABILITY ?
• Sustainable construction is concerned
with the economic, social, and
environmental impact of creating a
usable structure.
• It requires designers and contractors to
use building practices that will not cause
long-term damage to the environment.
• Sustainable buildings are designed to be
energy efficient, to be healthy for the
people who live or work in them, and to
reduce pollution and waste.

4. • WHY SHOULD WE BUILD SUSTAINABLE BUILDINGS ?
The consumer sectors responsible for the Global Warming
are ranked as:
•Buildings (48%)
• Transportation
• Industry

INTRODUCTION

5. • Dose building skeleton affect the building sustainability?
Structural engineering is an integral part of
green building design on number of fronts:
• Recyclability and reusability of materials
and systems.
• The choice of locally available materials
and resources.
• Resourceful use or efficiency of structural system.
• Provision for future adaptability of the buildings
• Numerous green building design strategies can have direct
impact on structural design of the building.
INTRODUCTION

6. LEED …
• The Leadership in Energy and Environmental Design (LEED™)
Green Building Rating System represents the U.S. Green
Building Council’s effort to provide a national standard for
what constitutes a “green building.” Through its use as a
design guideline and third-party certification tool
• It aims to improve occupant well-being, environmental
performance and economic returns of buildings using
established and innovative practices, standards and
technologies

7. LEED CREDITS
In order to be classified in LEED, the following requirements
should be considered:

12. ESTIDAMA …
• The Abu Dhabi Government has recently
initiated the Estidama Buildings and
Communities Program under the direction of
the Emirate of Abu Dhabi Urban Planning
Council (UPC).
• The ultimate goal of this ambitious program
is to transform Abu Dhabi into the
sustainable capital of the Arab world
• The Interim Estidama Community Guidelines
(IECG) are an important element of this effort.
• The objective of these guidelines is to guide
residential, commercial, and institutional
projects in a way that will build sustainable
developments, neighborhoods, and
communities in the Emirate of Abu Dhabi.

14. RELATION BETWEEN PRECAST & SUSTAINABILITY
Comparison on the three building structure materials,
upon LEED rating system.
• According to LEED, the material used for
construction affects the rating of the building..
• Precast concrete is considered the most efficient
material to be used in construction since it
complies with all LEED credits and prerequisites.

17. Credit 5.1: Site Development,
Protect or Restore Habitat:
• The requirements are met by limiting
site disturbance.
• Since precast concrete sound wall
systems are manufactured off site
and delivered on demand, there is a
significant reduction in truck traffic,
dust, noise and debris from
formwork
• precast concrete structures, and
manhole can be used to help obtain
this point.
RELATION BETWEEN PRECAST & SUSTAINABILITY

18. Credit 5.2: Site Development,
Maximize Open Space:
• The intent of this credit is to provide
a high ratio of open space to
development footprint.
• The requirements are met by limiting
the size of the development
…..footprint,
specifically by exceeding the local
zoning’s open space requirement.
• Pre-cast, pre-stressed concrete
skeleton can be used to help obtain
this point.
RELATION BETWEEN PRECAST & SUSTAINABILITY

19. Credit 7.1: Heat Island Effect,
Non-Roof:
• The intent of this credit is to reduce
heat islands’ to minimize impacts on
microclimates and human and wildlife
habitats.
• Pre-cast concrete with SRI of at least 29
used in the hardscape, or in the open-
grid pavements, can be used to help
obtain this point.
RELATION BETWEEN PRECAST & SUSTAINABILITY

20. Prerequisite 2: Minimum
Energy Performance:
• All buildings must comply with
certain sections on building energy
efficiency and performance as
required by the ANSI/ ASHRAE/IESNA
90.1-2007.
• Insulating to meet or exceed the
requirements of the standard is
generally a wise business choice.
• Pre-cast sandwich panel walls, can be
used to help obtain this point.
RELATION BETWEEN PRECAST & SUSTAINABILITY

21. Credit1: Building Reuse, Maintain
55%, 75%, 95% of Existing Shell:
Precast concrete panels can be reused
when buildings are expanded. Concrete
pieces from demolished structures also
can be reused in other applications.
Because the precast process is self-
contained, finishing materials are
reused, while concrete steel forms have
practically unlimited service lives.
RELATION BETWEEN PRECAST & SUSTAINABILITY

22. Credit 2.1: Construction Waste
Management, divert 50%, 75%
by weight or volume:
Precast concrete can be designed to
optimize or lessen the amount of
concrete used. In the plant, precast
concrete generates low amounts of
waste, and the waste generated has
low toxicity.
RELATION BETWEEN PRECAST & SUSTAINABILITY

23. Credit 4 : Recycled Content:
In precast concrete, Industrial wastes
such as slag cement and silica fume
can be incorporated into the mix,
reducing the amount of cement, which
in turn reduces CO2 emissions.
RELATION BETWEEN PRECAST & SUSTAINABILITY

24. Credit5.1: Local/Regional
Materials:
The use of local materials reduces the
transportation needs for heavy
building materials, along with the
associated energy and emissions.
Most precast concrete plants are
within 200 miles of a building site. The
cement, aggregates and reinforcing
steel used to fabricate precast
concrete components, are usually
obtained or extracted from sources
within 200 miles.
RELATION BETWEEN PRECAST & SUSTAINABILITY

25. Credit 3.1: Construction Indoor
Air Quality Management Plan,
During Construction:
Concrete contains low to negligible
Volatile Organic Compounds (VOCs).
These compounds degrade indoor air
quality when they off-gas from
manufactured wood products such as
laminate, particleboard, hardboard
siding and treated wood. Concrete is
not damaged by moisture and does
not provide nutrients for mold growth.
RELATION BETWEEN PRECAST & SUSTAINABILITY

26. Credit ID: Innovative in
design:
Pre-cast concrete
applications, could contribute
in implementing new
intelligent solutions. Rising
the performance of HVAC and
heating systems, indoor air
quality, or pollution
prevention.
RELATION BETWEEN PRECAST & SUSTAINABILITY

27. Hollow core slab ventilation:
Hollow core slabs voids, could use
for the Stack Effect –pull out the
hot air in the night time, with cool
air from out side-. And could used
with installation of Radiant heat
tube.
This saves material and reduce
heating load.
RELATION BETWEEN PRECAST & SUSTAINABILITY

28. Photocatalytic cement:
Photocatalytic concrete decomposing
the harmful molecules in the
vicinity by an oxidation reaction.
Thus, fewer harmful chemicals and
more pure clean air is available.
Pre-cast concrete is ideal system for
using this type of finishing.
