Dear Sir,
With reference to the above-referred subject and EAC Minutes of Meeting (MoM), dated November 30th
2017, our point-wise reply of the queries are as follows:-
S.No. Queries Reply
1 A certificate from the local body supplying
water, specifying the total annual water
availability with the local authority, the
quantity of water already committed, the
quantity of water allotted to the project under
consideration and the balance water available.
This should be specified separately for ground
water and surface water sources, ensuring that
there is no impact on other users.
Water and sewer permission is attached as
Annexure 1.
2
The Air Quality Index shall be calculated for
base level air quality.
The air Quality Index of the project site is
151.
3 A detailed report on compliance to ECBC
norms.
ECBC compliance report is attached as
Annexure 2.
4 A detailed traffic management and traffic
decongestion plan to ensure that the current
level of service of the roads within a 05 kms
radius of the project is maintained and
improved upon after the implementation of the
project. This plan should be based on
cumulative impact of all development and
increased habitation being carried out or
proposed to be carried out by the project or
other agencies in this 05 Kms radius of the site
in different scenarios of space and time and the
• Main road connecting to the project site
is 75 m.
• Separate entry exit will be provided
Internal road width is 6 m wide.
• Speed breakers proposed at the entry
exit gate, at the entry/exit ramps of
basements and at regular interval of the
internal road.
• Signage for speed limit restricted to 20
kmph will be displayed along the
internal roads.
-
traffic management plan shall be duly validated
and certified by the State Urban Development
department and the P.W.D. and shall also have
their consent to the implementation of
components of the plan which involve the
participation of these departments.
• One way internal traffic movement is
proposed.
• Parking norm as per local regulation
5 The permission of the CGWA for abstraction of
ground water and for basement/excavation
dewatering.
This is an vertical expansion project so
permission of CGWA for basement/
excavation dewatering is not required.
Without getting approval from CGWA,
Ground water will not be extracted at any
stage of the project.
6 A certificate of adequacy of available power
from the agency supplying power to the
project along with the load allowed for the
project.
Power assurance letter is attached as
Annexure 3.
7 A certificate from the competent authority for
discharging treated effluent/ untreated
effluents into the Public sewer/
disposal/drainage systems along with the final
disposal point.
The same is attached as Annexure 1.
8 A certificate from the competent authority
handling municipal solid wastes, indicating the
existing civic capacities of handling and their
adequacy to cater to the M.S.W. generated
from project.
Municipal solid waste will be handled by
Ghaziabad Development authority
We trust that you will find the above clarifications / replies in-line with your requirements and looking
forward to get the environmental clearance for the project at the earliest.

Energy Simulation report has been compiled by Atmos Sustainable Solutions Pvt. Ltd. For located in
Gurgaon, India. The scope of the project is 3 Residential Buildings.
SOFTWARE SUMMARY
The Energy simulation report contains results of energy analysis of the Proposed Buildings, To establish the
building performance rating as per ECBC, energy modeling was carried out by using simulation software
called Trane TRACE 700.
The software is very well capable of simulating and analyzing on hourly basis.
This Simulation study shows that the project performs better as compared to the ECBC benchmark for
Energy Performance Index (Criteria 8). The proposed project shows 40.97% lower energy consumption than
ECBC benchmark EPI.
GRIHA COMPLIANCE
MANDATORY
- Compliance with Energy Conservation Building Code-2007 as per clause 14.1.1. (Mandatory)
- Compliance with thermal comfort conditions as per National Building Code-2005/ASHRAE 55 – 2010.
-Minimum 20% reduction below the benchmark for Energy Performance Index (EPI) as per ECBC. (2 Points)
APPRAISAL
As per ECBC Energy Performance Credit, Every 10% reduction in EPI of the building under a specified
category shall fetch additional 2 points to a maximum of 8 points (50% reductions in EPI from the
benchmark). (2-10 points)
