Operational SavingsDaylights & ViewsAir Quality

A typical office building would require purging of fresh air of about 15 cfm/person which provides a fresh ambience inside the building.

According to the statistics proven, these conserve 40-50% of energy, 20-30% water compared to that of conventional buildings.

 The green buildings conserve:

39 % of total energy use, 12 % of total water consumption,68 % of total electricity consumption,38 % of total carbon dioxide emission.

Need for study

Research MethodologySITE DATA

The site for the USP Campus in Hyderabad measures

approximately 4 acres. The site has access roads along the

South, East & Western.

The site has a contour drop of around 8.0m from East to

West and the terrain is rocky with rock outcrops on the

eastern parcel of the site.

Being a rocky land the design is such that the excavation is

minimized to avoid rock cutting.

The main material used in the construction of research

centre using Green building technology is, the total

building is constructed with “Light weight concrete”.

Survey Drawing No: MP-SY-2001 version R0

NEW ECO-FRIENDLY PRODUCT IN MARKETLight Weight Concrete:Autoclaved aerated concrete (AAC), 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 and mold resistance. AAC products include blocks, wall panels, floor and roof panels, and lintels.1920s by the Swedish architect and inventor Johan Axel Eriksson.

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.

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.

STRUCTURAL,INTERIORS AND ARCHITECTURAL

General building design procedure:Step 1: Plan the approximate layout of the building Step 2: Calculate dead and snow loadStep 3: Design steel roof decksStep 4: Select OWSJ’s (Open Web Steel Joist) Step 5: Design beamStep 6: Design columnStep 7: Design steel column bore platesStep 8: Design footingStep 9: Create engineering drawingStep 10: Final check and submission.

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.

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

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.

The nominal cover provided to reinforcement would be:

Foundation and retaining walls 50mm

Column 40mm

Beams 25mm

Slabs 20mm

Stair case waist slab 20mm

Walls above ground 25mm

Parapets and Balustrade 25mm

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.

Loading CriteriaDead and Super Imposed Dead loads:

Balustrade Loading: Balustrades are to be designed as follows:

All other handrails, balustrades and the like, including parapets and railings to all roofs, shall be designed to resist a static load of 0.75 kN/m acting inward, outward or downward, or the appropriate wind load, whichever produces the most adverse effects.Balustrades, which may be called upon to restrain crowds or people under panic conditions, are to be designed for a load of 3 kN/m.

Geo technical Conditions:  Based on prevailing data of nearby areas, safe

bearing capacity of soil considered for the design calculation is 230 kpa at 1.5 mts depth. However, design calculations shall be revalidated after the receipt of soil exploration report of the project site.

Beam and Slab Option:Reinforced Concrete framed structure with 600 x 750 mm RC Columns with Shallow beams 600 mm deep x 750 mm wide are provided to support 200/225/250 mm thick slabs along larger span and 450 x 600 mm beam along shorter span. The floor panels are typically 12.55 x 8m in most of the cases. This conventional system of construction is ideally suited for a low rise development where there is adequate headroom available. However the beam depths are kept to least possible dimension to maximize the head room but still satisfy the serviceability and strength criteria set out in IS 456.

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.

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.
