EXECUTIVE SUMMARY

This report has been prepared for Sheetal Sagar,

Residential cum commercial redevelopment project,

Mumbai. This report is part of a process towards

obtaining Environmental Clearance from MOEF. The

specific objective of this report is to evaluate annual

energy usage and apply various energy efficiency

measures for ECBC Compliance for maximum Energy

Efficiency.

The building was analyzed using hourly energy

simulation to evaluate the performance in terms of

energy consumption and thermal comfort of the

occupants. The purpose of this report is to present

the performance of the design building in

comparison to a baseline budget building based on

ECBC 2007.

It is observed via various analysis tools that the

buildings are properly Shaded, Naturally ventilated

& has sufficient Daylight. It is determined via

simulation that the Tenant Building 1, saves 1.06%

in Energy over the ECBC 2007 mandated baseline.

Similarly Tenant Building 2, saves 3.30% in Energy

In addition to this, if we consider Solar PV

generation, the final saving will rise to 4.70% over

the ECBC 2007 mandated baseline

The report is structured as follows.

CLIMATIC ANALYSIS :

The Psychrometric Chart above explains that, no other strategy is effective for passive comfort except Shading &

Ventilation. Around 20% of total comfort hours can be achieved by Sun Shading & Natural Ventilation. 10% can be

achieved by ceiling fan forced ventilation & for the rest 70% of the time air conditioning may be required. For this

analysis, the Comfort Criterion was set at 22 to 26 degree C for dry bulb temperature & relative humidity to 70%.

The graph plot on next page clearly shows the degree difference between the Dry Bulb Temperature & Relative

Humidity. That’s why strategies like Evaporative cooling, Thermal mass, Night purging etc. will not be effective at

all. The Pshychrometric Chart above confirms that the only two effective strategies are Shading & Ventilation. As

per the legend, at least 30% of the total hours are in comfort range with an effective wind speed of 3 to 5 m/s. Fan

forced ventilation is certainly an effective strategy & comparatively cheaper than AC.

Next is he annual wind pattern of Mumbai city. The purpose is to understand this Wind Pattern. If you observe

the legend carefully, you will understand that, 10% of the total annual wind is flowing from West direction, which

has a temperature C, with a humidity around 70% & maximum wind speed is 8 m/s at one point of time. The

predominant wind direction in Monsoon Period is West – South-West.

SHADING ANALYSIS:

Mutual shading plays an important role in heat gain through envelope. Though envelope insulation has more

contribution towards heat gain reduction, at the same time Mutual & Window Shading is also effective. The

project team has consciously designed the shading devices reducing insolation on walls & windows. The analysis

confirms that proposed shading devices help to reduce incident radiation on envelope resulting in lesser heat load.

METHODOLOGY -

Virtual analysis tool – Ecotect has been used with the above information as a basis for the commentary provided

in this report. To determine impacts of the proposed project structures, the 3D virtual model of the proposed

building and surrounding structures were created in the software. Actual weather file of Mumbai were used for

the simulation.

OBJECTIVE -

The aim of the study is to assess the potential impact of proposed shades on the building envelope. The effects of

shading by one building upon another can be either positive or negative depending upon the site-specific

circumstances of the properties involved. A potential benefit of shading for adjacent structures may be a cooling

effect gained during warm weather. Negative consequences of shading include the loss of natural light for passive

or active solar energy applications or the loss of warming influences during cool weather. Factors influencing the

relative impact of shadow effects are site-specific and include differences in terrain elevation between involved

properties, the height and bulk of structures, the time of year, the duration of shading in a day, and the sensitivity

of adjacent land uses to loss of sunlight.



HOURLY SHADOW PATTERNS -

CONCLUSION -

Shading analysis confirms that more than 40% of the walls & windows are shaded due to mutual and shading

devices designed in the project.

HEAT ISLAND EFFECT:

Urban development has serious effects on the global environmental quality, including the quality of air, increase in

temperature and traffic congestion. Construction of building itself is related to global changes in terms of increase

of urban temperatures, the rate of energy consumption, the increased use of raw materials, pollution and the

production of waste, conversion of agricultural land to developed land, loss of biodiversity and water scarcity. An

urban heat island is a climatic phenomenon in which urban areas have higher air temperature than their rural

surroundings as a result of anthropogenic modifications of land surfaces, significant energy use and its consequent

generation of waste heat. Thus, this might prove to be an unsustainable factor that leads to excessive energy use

for cooling and putting the urban population at great risk for morbidity and mortality. According to the above

perspective and considering that rapid and huge population growth is expected in the near future, it becomes

increasingly important to apply heat island mitigation strategies in order to reduce energy consumption and

improve the quality of life.

Effects of Urban Heat Island

• Increased in cooling demand;

• Increased in energy usage;

• Increased air pollution;

• Increased CO2 emissions;

• Climate change;

• Increase health problems;

• Heat related illness & death;

• Impaired water quality

Absorption of solar radiation

During the day in rural areas, the solar energy absorbed near the ground evaporates water from the vegetation

and soil. Thus, while there is a net solar energy gain, this is compensated to some degree by evaporative cooling.

In urban development, where there is less vegetation, the buildings, streets and sidewalks absorb the majority of

solar energy input.

CONCLUSION -

From the results on the next page, it can be clearly seen that because of measures like Solar Panels on roof, Light

Coloured or Open Grid Pavers, Shaded Streets, Maximum Green Area etc. there is a considerable decrease of 78%

in the Surface Absorbed Radiation resulting is reduction of Cooling Loads.



Case 1: The case has been assumed with all the proposed buildings with convectional finish on top, asphalt road and dark colored paving on site without any green space.

Case 2: The case has been proposed with light coloured road surface and paver blocks with green space in open area areas which is help to reduce urban air temperature in surroundings.

RETScreen is widely used software for renewable energy calculations. The snap shot of the same is

provided here to understand the PV cell calculations in detail.

Considering the Sun Path of Mumbai city, it is recommended to install PV cells on south side at an angle

of 20 Degree facing South for maximum average efficiency round the year. The efficiency of the PV cell

is considered as 14% & inverter is 85%.

Considering all these factors & climate of Mumbai city (As per ISHRAE Weather File), it is calculated that,

solar PV of 22 KWp capacity will generate 27 MWh electricity annually For tenant Building 1. Similarly

solar PV of 15 KWp capacity will generate 18 MWh electricity annually For tenant Building 2.



ENERGY ANALYSIS:

Proposed Sheetal Sagar Residential cum commercial

redevelopment project, Mumbai which lies in

western India. The total built-up area of residential

buildings is about 27,106.57 m2 distributed over a

large area along with club house facility & other

amenities. The overall Window to Wall Ratio is

approximately 25%.

A zoning plan was developed for each floor &

entered into the simulation model. Each zone was

assigned a set of properties including lighting power

density, equipment power density, occupancy rate,

outside air requirement etc. Each zone was also

assigned physical properties of floor-to-floor height,

material conductivity & fenestration area etc.

A baseline building as per the properties stated in

ECBC 2007 was modelled. The Building was

simulated with actual orientation and again after

rotating the entire Building by 90, 180 & 270

Degrees and then the annual energy consumption

results were averaged out to get the ECBC 2007

Baseline Building Energy consumption in kilowatt

hours. As per ECBC 2007, the average base case

energy consumption does not consider the effect of

building shades & overhangs.

A wide range of actual as-designed parameters such

as Envelope (roofs, walls), Windows (type of

window glass), Lighting (lighting power density),

reduced Exterior Lighting, efficient system design

were added to the Baseline case to simulate the

performance of the designed building.

The project has been modelled with the e-QUEST

energy analysis software that uses the DOE 2.2

Building energy simulation engine. The e-QUEST

energy modelling software allows for a graphical

display of all the 3-dimensional geometry entered in

the application to describe the building. As per the

view shown, the Building has been modelled in detail

to improve the accuracy of analysis work. The

project objective is to evaluate energy use and the

energy efficiency performance of the Building.



TENANT BUILDING 1

BASELINE MODEL

The ECBC 2007 Minimally Compliant Baseline model

is used to benchmark the design case. This model

geometry is based upon the design case, but the

performance parameters listed below are defined to

reflect the minimum efficiency levels that ECBC 2007

defines for various building components.

These parameters are listed below.

rooms are modelled as conditioned spaces with

unitary air conditioners assigned to each zone

with COP 3.0. Kitchen areas are modelled with

unit ventilators.

Based on above parameters. The average base-case

consumption is 1704 MWh.

The annual energy consumption for baseline case,

broken down by end-use shows that Lighting (27%)

and Equipment (27%) are the largest components

after HVAC (36%).

1.06% savings over baseline.



SUMMARY

The Proposed case model shows significant savings

in internal lighting as well as space cooling energy

consumption as compared with the ECBC 2007

stipulated baseline model. These energy reductions

can primarily be attributed to improved lighting

power density and reduction in cooling loads due to

improved envelope and glazing specifications.

For the purposes of determining energy savings in

rupees, the energy costs for the proposed case

model are compared to the energy costs for the

ECBC 2007 minimally-compliant model.

envelope and equipment, it is noted from the results

of energy simulation that by using efficient envelope

and lighting, the total annual energy required for

Proposed Residential cum commercial

redevelopment project, Mumbai for tenant building

1 is 1686 MWh. The energy required for the baseline

model is simulated to be 1704 MWh. The total

energy cost saving is 1.06%.

Heat Gain Calculation – Building Peak Load Components - LS-C Report, has been analysed here. The building heat gain

comparison between base case & proposed case is as follows. It is clearly observed from the

table below that, for a naturally ventilated residential building, Envelope Shading is also an

effective strategy along with insulation. Though the Base case (With Insulation – Without

Shading) still has a lesser heat gain as compared to Proposed case (Without Insulation – With

Shading), but the difference is marginal & can be easily compensated by reducing lighting &

Equipment consumptions. This is possible mainly because Reduced Sol Air Temp & Shaded

RETScreen is a widely used software for

renewable energy calculations. Considering

the Sun Path of Mumbai city, it is

recommended to install PV cells on south

side at an angle of 20 Degree facing South for

maximum average efficiency round the year.

It is calculated that, solar panels of 45 kWp

capacity will generate around 175 KWh per

day electricity annually.
