INTRODUCTION
CERTIFICATION
Independent third party verification that the building project meets highest
performance standards.
40% of the carbon dioxide that contributes to our warming planet comes from
buildings.
Some of it is a secondary effect of operational needs such as electricity, a/c, and
heating, many ghg’s arise from resource extraction, manufacturing and production
of the building materials themselves.
Choosing ingredients wisely makes all the difference in terms of the overall impact
of the building throughout its life. -‘Environmental footprint’ or ‘life cycle
assessment’
The materials are in the picture from the first round of planning to the final stages
of demolition or renovation of a building or product.
Resource Reuse
Reuse building materials and products in order to reduce demand for virgin
material and reduce waste, thereby reducing impacts associated with the
extraction and processing of virgin resources.
Requirements :
Use salvaged or refurbished materials for 5-10% of building materials
(by value)
Methods suggested like, reuse of partition panels,broken tiles,Used
carpets.(Note : Movable furniture like chairs are not accounted for
calculation)
Recycled content
Increase demand for building products that incorporated recycled content
materials, therefore reducing impacts resulting from extraction and
processing of new virgin materials
Requirements :
Use materials with recycled content such that the sum of post –consumer
recycled content plus one-half of the post-industrial constitutes at least
5% of the total value of the materials in the project.
The value of the recycled content portion of a material or furnishing shall
be determined by dividing the weight of recycled content in the item by
the total weight of all material in the item, then multiplying the resulting
percentage by the total value of the item.
LOCAL/ REGIONAL MATERIALS
Increase demand for building materials and products that are
extracted and manufactured within the region, thereby supporting
the regional economy and reducing environmental impact resulting
from transportation
Requirements :
Use a minimum of 20 %( extra points for going up to to 50 %) of
building materials and products that are manufactured regionally
within a radius of 800 kms (manufacturing refers to the final
assembly of components)
FURNITURE IN GETTING
CREDITS
Provision of energy efficient task lights, can help in reducing the overall
lighting load of the project.
Use of easily recyclable material (like corrugated cardboard, expanded
polystyrene) packing which can reduce landfill disposal.
Manufacture products with longer life cycle, so that can be used in many
sites. Tile – frame construction making it easy for reconfiguration and reuse
Identifying components which could be made from recycled materials like,
recycled plastics, worktop made of baggage boards etc.
Task lighting feature can ensure better control and proper optimization of
electricity Used for lighting
Can explore the option of using boards made of bamboo, fabrics made of
agricultural waste etc.
Working towards usage of material which confirm to VOC level

Formation of positive and negative pressure zones when wind flows around
rectangular and circular bodies.
The pressure coefficient cp can be used with the wind velocity to calculate
positive and negative pressure loads.

Solar
Photovoltaic
The solar panels are placed on the
eastern side and they are sloping
which helps production of energy
throughout the day and as it is a
commercial building more amount of
energy is consumed during the
working hours [day] compared to the
evenings.

Wind System
Wind tower with evaporative cooling
Due to the unpredictable wind direction, opening on all four sides are provided with an additional
affect due to wind pressure. The rate of heat transfer mainly depends on surface area with which,
the air comes in contact. Here the surface area is increased by having vertical conduits, which
gives less resistance to air flow. Further, the effectiveness is increased by having sprinklers to
promote the evaporative cooling
WIND
DEFLECTORS
Interior partitions are provided in
the building for various purposes of
privacy, which may not allow
openings in the partition. In this
region, due to the warm and humid
climate ventilation becomes very
essential, cross – ventilation
becomes the major solution. This
can be overcome by providing
ridge ventilation or ventilating
ducts or shafts for deeper rooms.
The effect of positioning the apertures at various heights above the floor
influences the efficiency of the natural ventilation in a given space.
Meet the basic physical, emotional and spiritual needs of the occupants
Consider healthy lighting, color and sound, controlled temperature and humidity and
good indoor air quality to enhance the living environment
Apply an integrated wiring system for lighting, power, security, fire alarm and audio
facilities.
Vegetation that was lost to the built area was replaced by gardens on 55
percent of the roof area.
