EXECUTIVE SUMMARY
The Proposed expansion of ‘Neelkanth Woods’ project is
located on Mulla Baug, Near Hill Crest Society, Off
Ghodbunder Road, Thane (W), Mumbai, Maharashtra.
The project site is located in the fully urbanized Thane
Municipal Corporation area with all basic amenities in
the study area such as bus stations, railways, hospitals,
educational institutions etc.Through this report the
project intends to highlights energy performance
compliance in accordance with ECBC standards. This
reports shares the project features and their influence to
help achieve energy efficiency along with a comparative
analysis of the energy performance against
benchmarked performance expected using ECBC
stipulated energy efficiency standards.
The project obtained Environment Clearance (EC) in
2007 vide letter No. 16-P46/2007(ENV)/2933. EC was
obtained for development of plot area of 1,77,735 m2
and built up area of 85,195.34 m2 for 6 residential
towers (Stilt + 28 Floors) 88 bunglows (Stilt + 2 Floors), a
club House and convenience shops.
The project site is located in the fully urbanized
Thane Municipal Corporation with all basic
amenities in the study area such as Thane bus
stations, Thane railway station, hospitals,
educational institutions etc.
The study herein sheds light on the influence of few
features incorporated in building design to help achieve
energy efficiency and further proposes few editions and
alterations that can achieve higher grade of energy
efficiency.
The method to highlight ECBC compliance is by
comparing the change in energy recorded by using
energy simulation models in “eQUEST”. Two design cases
were used on the building models wherein the energy
performance from former case was estimated using ECBC
benchmarked design standards, and the latter design
case was estimated by incorporating intended project
design features. The difference in energy performance
thereby helps identify and reflect on the status of the
compliance and grade of compliance achieved. The
project complies with ECBC standards by achieving
energy reduction lower to that expected by use of ECBC
benchmark design standards. This was achieved by virtue
of the envelope design however the proponent intends
to further enhance and extend the threshold of energy
efficiency. For this efficient lighting systems and solar hot
water have been incorporated in the project energy use.

The graph above highlight the energy consumption
difference achieved by virtue of envelope measures,
savings in LPD and solar hot water.
The expected change in energy use is shared below.
The project complies with ECBC design standards by
consuming 1.3% less energy annual when compared
with energy estimated using ECBC design standards.
METHODOLOGY
The scope of this study is to examine the influence of the
proposed building design features to help meet with the
regulatory energy design benchmarks stipulated in the
ECBC guidelines. The study examines the influence of
few features incorporated in building design to help
achieve energy efficiency. This level of efficiency and
performance grade is compared with energy
performance achieved by incorporating ECBC specified
baseline design standards in the same building design.
The former part of the report shares the Benchmark
compliance codes and specifications stipulated by ECBC
whereas the latter section compares the energy use
estimations using the two different models. The design
features of the proposed building design are referred as
PROPOSED CASE. ECBC stipulated baseline design is
termed as BENCHMARK CASE in the report.
The performance achieved by virtue of the envelope
design in the proposed building is compared with
benchmark performance observed using envelop
specifications as per ECBC standards, as well as further
energy trade-offs, such that the overall expected energy
consumed by the project equals the energy expected to
be consumed using absolute design standards by ECBC.

CLIMATE ANALYSIS for Mumbai, India
It is important to identify key external climatic conditions
for this site which have influence on the solar heat gain,
daylight and thermal comfort conditions.
LOCATION: Ghodbandar road, Thane, Maharashtra, India
CLIMATE ZONE: ECBC type: Warm and Humid
Solar Radiation Chart
Monthly diurnal averages for available and direct solar
radiation.
The site by virtue of its location has abundance of solar
exposure and can benefit from in the winter periods.
Solar exposure from summer periods can be avoided.
Sky Cover
85 to 90% sky cover during the monsoon period which
ranges from June to September impacts available
daylight level. This sky condition also reduces solar heat
gains. Impact of reduced heat gains can be readily
realized on active cooling loads whereas lower daylight
levels impacts reliance on artificial lighting.
Annual sky cover range.
Sun Path
Thane region located 18 degree above the equator
receives direct sunlight predominantly from the
southern façade. Northern facade receives direct
incident solar radiation for two months (summer) of the
year.
Sun path for the development (with focus on open
areas)

conventional method is estimated to be about
1146.2 MWh of energy for the entire year. As per
ECBC section 6.2.1, for consideration in the ECBC
base case design, only 20% of this energy
consumption has been considered on solar.
Results and Comparative
The energy performance of the proposed case with
two variations is compared with Benchmark
performance observed using ECBC standards. The
comparative between the two are shared below

Please refer to Annexure 2.
The project complies with ECBC design standards
by 1.3% less energy annual when compared with
energy estimated using ECBC design standards.
The design features of proposed case help achieve
better performance than design features in
accordance with ECBC benchmark. Thus the design
helps comply with ECBC standards.

In addition to this, the project features roof top
Solar PV of 378.6 MWh of annual generation
potential. By including this renewable energy
source the expected demand energy from the
proposed design further reduces by 2.5% from
ECBC base case benchmarks.
