GREEN BUILDING FEATURES IN BUILDING
1. INSULATED BUILDING ENVELOPE THUS REDUCING AC LOAD OF THE
BUILDING BY ALMOST 30% BY USING:

COMPOSITE WALLS: composite brick & stone masonry with 75mm thk cavity filled
with glass wool insulation.

ROOF INSULATION: Over deck insulation using 55mm thick Polyurethane Foam on
Terrace roof slabs and finished with a reflective layer of mosaic flooring using broken glazed
tiles pieces for reflecting the solar radiations.

DOUBLE GLAZING: Double glazed dual sealed insulated units for glazing have been
used.
 COURTYARD PLANNING- Building has been planned around 100’x100’ extensively
landscaped courtyards ensuring
- Ample natural light in all common areas like Lifts, stairs & lobbies; minimizing
dependence on artificial lighting & external view for most of the officials
- Glazings have been provided in corridor walls to enhance natural light penetration
- Light cut-outs in courtyards to ensure natural light penetrating both levels of basement
2. LANDSCAPE FEATURES:




Maximizing pervious & green surfaces to almost 60% of site area
Concrete roads around the building instead of black bituminous road for high
reflectance
Extensive landscaping, using native plants, in courtyards, terrace gardens & around
the building reduces the ambient temperature around the building
Provision of ‘VERTICAL GREEN WALL’ in landscaped areas
3. Use of Energy Efficient technologies





VRF air conditioning system has been provided using non-CFC refrigerants and Heat recovery
wheel to pre-cool fresh air
Machine room less and gearless lifts have been installed which reduce the energy consumption
by about 25%
Use of SPV panels for hot water in Kitchen
Use of mirror optic fixtures, CFLs and occupancy sensors.
External & façade lighting have been designed as per following norms



Facade lighting lpd= 50% of Ashrae norms
External street lighting lpd = 80% of Ashrae norms
No light trespass & no upward light flux

Effective water management in building by
 Use of Hydro-pneumatic water distribution system
 Sensors in urinals and water taps
 Dual flushing cisterns (to reduce water consumption)
 Use of STP treated water for flushing & irrigation

Segregation of Bio-degradable waste generated by end users

Desirable Indoor Air Quality has been maintained by
o Providing CO2 sensors in Meeting rooms
o Providing TFA system to supply fresh air (21CFM/ person)
o Providing CO sensors in basements
o Use of low VOC products like paints, adhesives, sealants, carpets etc.
o Use of foot mats before entrances to reduce the dirt particles entering the interiors
BMS system has been proposed in the building to integrate all the services of the building
through a software interface to achieve the optimization of resources and monitoring of the same
in pretext of the historical data of the building. It also includes graphical representation of data
and reports, alarm management and building systems respond in coordinated manner in case of
emergency.

4. Minimum impact on environment during the course of construction by using
following controlling measures



Soil erosion & sedimentation control during excavation & construction stage. Preservation
of good earth by stacking the complete excavated earth (1.5 lakh cu.m.) at Sunder Nagar
nursery for fresh plantation
Site screening (up to a ht. of 20’) and regular sprinkling of water to suppress spreading of
dust in the air & surrounding areas
Cleaning of vehicle tyres before leaving the site & regular washing of surrounding roads




Construction waste was segregated & sent to Municipal waste facility, thus not allowing it
to mix with ground water. Also it was ensured that there was no slippage of lubricant, waste
oil etc. into the ground contaminating the soil & leaching into the Ground water.
Ambient noise level was maintained within permissible limits by use of 4no. silent type
D.G Sets for the project, meeting environmental (air & noise) emission standards
Relevant quality check compliance reports for Air, Water & Noise levels were sent to
MoEF (Ministry of environment & forest) and DPCC on 6 monthly basis
Use of regional materials at site as majority of the materials have been procured within 250
kms from site
5. Recycling of Material:
a. Use of waste brick bats for filling in landscaped areas and water proofing treatment
of terraces.
b. Use of waste pieces of glazed tiles on terrace to reflect solar radiation.
(c) Use of recycled materials such as ‘Aerolite’ calcium silicate false ceiling tiles,
calcium silicate ‘HILUX’ board, gypsum board in partitions and fly ash bricks etc.
