INTRODUCTION

4. SITE
SITE PLAN BUILDING ALLIGNMENT
- PRESERVATION OF THE LOCAL ECOLOGY,
- TREE CUTTING APPROVALS FOR 46, BUT ONLY 19 CUT
- 11 TREES TRANSPLANTED
- EXCAVATED SOIL REUTILIZED AT OTHER CONSTRUCTION
SITES AND THE ZOO
-WIDER FRONT SETBACK (22M) TO PROTECT FRONT TREE
LINE
-PRESERVE THE INTEGRITY OF THE GREEN STREET

5. ENVIRONMENTAL RESPONSE

- MAXIMUM GROUND COVERAGE USED (30%) TO KEEP BUILDING
HEIGHT COMPARABLE TO THE SURROUNDINGS

9. ZERO ENERGY
ENERGY CONSUMPTION ON SITE
ANNUAL ENERGY PRODUCTION &
CONSUMPTION (MWH)
 IPB REDUCES ENERGY REQUIREMENT BY 70% OVERALL
 N-S ORIENTATION – LIMITING WWR – INSULATION ON
WALL & ROOF– EXTENSIVE GREENERY TO REDUCE HEAT
LOAD
 MAXIMIZING DAY LIGHTING TO REDUCE LIGHTING LOADS
 EXTREMELY LOW LIGHTING POWER DENSITY – 5W/SQM
 PLANNING TO MINIMIZE AC LOADS (KEEPING OPEN
ATRIUM FOR CROSS VENTILATION, NON CONDITIONED
LOBBIES)
 EFFICIENT HVAC WITH SCREW CHILLERS, VFD’S, CHILLED
BEAMS
 GROUND BASED HEAT EXCHANGE FOR CONDENSER
WATER REMOTE COMPUTING - THIN CLIENT SERVERS
 ENERGY EFFICIENT APPLIANCES (5 STAR BEE)
 SPV’S FOR THE REMAINING LOAD

10. GEOTHERMAL COOLING ACTIVE CHILLED BEAMS

12. MATERIALS USAGE OF MATERIALS WITH LOW EMBODIED ENERGY
 STONE AVAILABLE IN NEARBY AREA FOR FLOORING
 TERRAZZO FLOORING WITH LOCALLY AVAILABLE STONE
MATERIALS.
 FLY ASH BRICK.
 AAC BLOCKS.
 JUTE BAMBOO COMPOSITE FOR DOOR FRAMES &
SHUTTERS.
 UPVC WINDOWS WITH HERMETICALLY SEALED DOUBLE
USING LOW HEAT TRANSMITTANCE INDEX GLASS.
 USE OF HIGH REFLECTANCE TERRACE TILES FOR LOW
HEAT INGRESS.
 AVOIDED ALUMINUM AS IT HAS HIGH EMBEDDED
ENERGY
 SANDSTONE JALIS.
 STONE AND FERROCEMENT JALI
 BAMBOO JUTE COMPOSITE DOORS AND FRAMES &
FLOORING
 HIGH EFFICIENCY GLASS, HIGH VLT, LOW SHGC & LOW U-
VALUE,
 OPTIMIZED BY SHADING
 LIGHT SHELVES FOR BRINGING IN DIFFUSED SUNLIGHT
 USE OF MATERIAL AVAILABLE HAVING RECYCLED
CONTENT

13. COOL ROOF
 A cool roof is one that has been designed to reflect
more sunlight and absorb less heat than a standard
roof.
 Cool roofs can be made of a highly reflective type of
paint, a sheet covering, or highly reflective tiles or
shingles.
 Nearly any type of building can benefit from a cool
roof, but consider the climate and other factors before
deciding to install one.
 Terrazzo flooring is composed of composite
material.
 It contains any variety of mixture of aggregate
chips like stone or marble and either epoxy
resin or concrete.
 It can be used both indoors and outdoors and
can be poured as concrete or laid in tiles.
TERRAZZO FLOORING

14. FLYASH BRICK
 FLY ASH CAN BE A COST-EFFECTIVE SUBSTITUTE
FOR PORTLAND CEMENT IN MANY MARKETS.
 FLY ASH IS ALSO RECOGNIZED AS AN
ENVIRONMENTALLY FRIENDLY MATERIAL BECAUSE
IT IS A BYPRODUCT AND HAS LOW EMBODIED
ENERGY, THE MEASURE OF HOW MUCH ENERGY IS
CONSUMED IN PRODUCING AND SHIPPING A
BUILDING MATERIAL.
 BY CONTRAST, PORTLAND CEMENT HAS A VERY
HIGH EMBODIED ENERGY BECAUSE ITS
PRODUCTION REQUIRES A GREAT DEAL OF HEAT.
FLY ASH REQUIRES LESS WATER THAN PORTLAND
CEMENT.
UTILIZATION OF FLY-ASH IN BUILDING STRUCTURE- READY MIX CONCRETE WITH PPC HAVING MORE THAN 30% FLY ASH CONTENT.
REDUCE VOLUME, WEIGHT, AND CONSTRUCTION TIME BY ADOPTING EFFICIENT TECHNOLOGIES (SUCH AS PRE-CAST SYSTEMS)
ON SITE RENEWABLE ENERGY SYSTEM WITH SOLAR PHOTOVOLTAIC CELLS TO MEET TOTAL ENERGY DEMAND.

15. JAALIS (SANDSTONE)
 A PERFORATED STONE OR LATTICED
SCREEN
 THE JALI HELPS IN LOWERING THE
TEMPERATURE BY COMPRESSING THE AIR
THROUGH THE HOLES.
 WHEN THE AIR PASSES THROUGH THESE
OPENINGS, ITS VELOCITY INCREASES
GIVING PROFOUND DIFFUSION.
Natural stone Jalli and connecting corridors

16. SPACE FRAME
 AN ENTRANCE ATRIUM OF FOUR
STOREYS HEIGHT HAS BEEN MADE IN THE
MIDDLE OF THE NORTH BLOCK AND IN
THE ENTRANCE TO THE SOUTH BLOCK.
 THE BUILDING HAS LARGE SPAN TRUSSES
AT TERRACE AND SPACE FRAMES IN THE
CENTRAL COURTYARD TO SUPPORT
SOLAR PANELS.

17.  REGENERATIVE LIFTS FULLY AUTOMATED CAR PARKING IN BASEMENTS
 BUILDING ORIENTATION IN E-W DIRECTION
 BLOCKS CONNECTED WITH CORRIDORS AND CENTRAL COURTYARD
 BUILDING ENVELOPE DESIGNED TO ENSURE DAYLIGHT IN 75% OCCUPIED AREAS
 PLANTATION AND GRASSING IN MORE THAN 50% AREA
 GRASS PAVERS IN CIRCULATION AREAS
 TERRACE GARDEN
 ENERGY EFFICIENT AIR CONDITIONING SYSTEM AND LIGHTING
 CONVERSION OF BRAKING ENERGY INTO ELECTRICITY IN LIFTS
 CHILLERS AND AHUS WITH VFDS, HEAT RECOVERY WHEELS AND THERMOSTAT CONTROLS FOR HVAC
 LED LIGHTS, OCCUPANCY AND LUX LEVEL SENSORS
 930 KWP ROOFTOP SOLAR POWER PLANT
 LOW DISCHARGE WATER FIXTURES
 LANDSCAPING WITH NO HARD PAVING ELIMINATING HEAT ISLAND EFFECT
 FLY ASH-BASED PRODUCTS IN CONSTRUCTION
 SEWAGE TREATMENT PLANT OF 30 KLD CAPACITY.
 FEATURES:
i. CHILLED BEAM SYSTEM OF HVAC
ii. GEOTHERMAL HEAT EXCHANGE
ECO-FRIENDLY SYSTEM

18. ACHIEVEMENTS:
• 40% SAVINGS IN ENERGY
• ZERO ELECTRICITY BILLING
