9. NEW ECO-FRIENDLY PRODUCT IN MARKET
Light Weight Concrete:
Autoclaved aerated concrete (A
AC), also known as autoclaved
cellular concrete (ACC) or
autoclaved lightweight
concrete (ALC) was invented in
the mid- precast building
material that simultaneously
provides
structure, insulation, and fire
10. Advantages:
AAC’s excellent thermal efficiency makes a major
contribution to environmental protection by sharply
reducing the need for heating and cooling in buildings.
AAC’s easy workability allows accurate cutting, which
minimizes the generation of solid waste during use. Unlike
other building materials, AAC can eliminate the need to be
used in combination with insulation products, which increase
the environmental impact and cost of construction.
11. AAC’s high resource efficiency gives it low
environmental impact in all phases of its life cycle,
from processing of raw materials to the disposal of
AAC waste.
AAC’s light weight also saves energy in transportation.
The fact that AAC is up to five times lighter than
concrete leads to significant reductions in
CO2 emissions during transportation. In addition, many
AAC manufacturers apply the principle of producing as
near to their consumer markets as possible to reduce
the need for transportation.

21. Design Philosophy and Approach
for the Structural Design
The basic aim of structural design of the buildings
is to ensure the achievement of satisfactory behavior
during the intended design life. With appropriate
degree of safety they should sustain all the loads
coming during construction and use. Adequate
durability and fire resistance are other major factors
governing the design.
Robustness:
Proposed Structures are planned and designed, so that
they are not unreasonably Susceptible to effects of
accident wherein damage to small area of failure of
single element may lead to collapse of major portions
of the structure.
22. Serviceability:
The design properties of materials and the design
loads comply with design codes specified in later part
of this report and would typically include:
i. Deflection Criteria:
Deflection due to vertical loading:
Final deflection below level of supports should not be
greater than l/250 where l is the span of the member
or the length of the cantilever. Deflection after
installation of elements such as cladding and
partitions not greater than l/500 or 20mm whichever
is lesser.
ii. Response to wind loads:
Limiting the deflection to h/500 under design
conditions and the storey drift to 0.04 *Storey height
23. iii. Cracking of concrete:
Design surface crack width due to applied loads or
thermal or shrinkage effects not greater than 0.3 mm
iv. Vibrations:
By avoidance of discomfort or alarm to occupants,
structural damage or interference with proper functioning
v. Durability:
Durability is achieved by integration of all aspects of
design material and construction technology. The
environmental effect to which the concrete or steel is
exposed is taken into account during the design by
providing adequate cover to reinforcement and use of
protective coatings to structural steel works.
24. The nominal cover provided to
reinforcement would be:
STRUCTURAL ELEMENT COVER
Foundation and retaining walls 50mm
Column 40mm
Beams 25mm
Slabs 20mm
Stair case waist slab 20mm
Walls above ground 25mm
Parapets and Balustrade 25mm
25. vi. Fatigue:
Cyclical or repetitive loadings such as crane movement etc. shall be
catered for in the design of the relevant elements of the structure.
vii. Fire Resistance:
The design of structural elements is to be based on fire resistance levels
to satisfy BIS (IS 456:2000) requirements as advised.
Material Properties:
Concrete of design strength of 30 MPa will generally be used for
structural concrete works.
Columns strength would be enhanced to M35 in special cases as
determined by the Oncoming loads onto the building.
Reinforcing steel used in the design shall primarily be:
High Yield Twisted Steel bars Fe 415 with a characteristic
strength of 415 N/mm².
Welded Mesh reinforcement with a characteristic strength of
485 N/mm².
Mild steel reinforcement with a characteristic strength of 250
N/mm².

44. CONCLUSION
The green buildings gives the facility a campus feels, and creates an
environment of creative thoughts and interaction which will help in
exchange of ideas. The design shall also be energy efficient.
From the design point of view, the design specifications are to be
thoroughly satisfied, since no compromise can be made regarding the
stability of the structure.
Quality control plays a vital role in the construction of the structure.
The quality control department in the site is of major importance.
Appropriate precautionary measures are to be taken to avoid the use of
inefficient material.
The fire fighting system which can efficiently control the hazardous
effects of sudden fires and which minimizes the loss is importance in
this structure.
45. Safety and security plays a major role, because huge equipment man
power get involved while constructing these kind of huge structures.
Therefore, proper formulation of rules and regulations regarding
safety is mandatory.
The green building experiences in India have been exciting and
challenging as well. Since its introduction in 2001, the LEED rating has
emerged as a very useful tool in designing a green building. Now there is
an imminent need for service providers, who would be required in large
numbers, not in hundreds but thousands, as the movement is heading to
reach greater heights.
The green building movement is here to stay for the benefit of
individuals, society and the country at large.
