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.



4

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)

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.
