I. Introduction
Based on an inspection of the building (and some measurements), energy auditing
includes an evaluation and analysis of the existing situation and the various measures
that could be implemented to reduce the energy consumption and improve the indoor
environment. The results are presented in an energy analysis report describing the
recommended measures with corresponding investments, savings and profit.
The energy analysis in a building is a feasibility study, for it not only serves to identify
energy use among the various services but also identify opportunities for energy
conservation. The study should reveal to the owner, manager, or management team of
the building the options available for reducing energy waste, the costs involved, and the
benefits achievable from implementing those energy-conserving opportunities (ECOs). It
is to reduce waste of energy and money to the minimum, permitted by the climate in
which the building is located, its functions, occupancy schedules, and other factors. It
establishes and maintains an efficient balance between a building's annual functional
energy requirements and its annual actual energy consumption.

III. Assessed Parameters
Geology of Jaipur, Rajasthan Jaipur city is the capital and largest city of the Indian state of Rajasthan. Its municipal boundary of the city extends from 26⁰46' N latitude to 27⁰01'N latitude and 75⁰39'E
longitude to 75⁰57'E longitude. The city is surrounded by the Nahargarh hills in the north
and Jhalana in the east, which is a part of Aravalli hills ranges. To its south and west, the
city is surrounded by isolated and discontinuous hillocks. The southern end of the city is
an open plain stretching far and wide towards Sanganer and beyond. The city was initially
located within the walls with the rocky streets providing an easy drainage system on
either side of the city but the later extension of the city took place towards the south and
west on the alluvial plains formed in the confluence zone of the Amani Shah Nala in the
west and Jawahar Nagar Nala in the east and beyond.
Climate Jaipur city falls under the semi-arid of climate and experiences a continental type of
climate owing to its proximity to the desert and inland location. It is characterized by hot
summers and cold winters. The mean temperature of Jaipur is 36⁰C varying from 18⁰C in
winter (January) to 45⁰C in summer (June). The normal rainfall of Jaipur is 600 mm nearly
90 percent of which takes place in the summer monsoon period from (June to September)
and the rest comes from the winter cyclones:
Table 1: mean temperature of jaipur
Temperature and Rainfall The month of May experiences the maximum temperature and January experiences
minimum temperature. The data is based on 7 observation years recorded by Indian
Meteorological Department (IMD). Jaipur city recorded the maximum temperature of
45.2°C and minimum temperature of 2.5°C in the year 2001 and the maximum
temperature of 45.7°C and minimum temperature of 2.2°C in the year 2011.
Heat wave prevails for a few days when day temperature rises 4°C to 6°C above normal.
During winter season, minimum temperatures remain at about 4°C to 9°C and fall below
0⁰C when chilly winds (northerly) blow from the Himalayan region. Mist and Fog occur
in the morning hours after passage of western disturbances. The minimum
Mean Maximum Temperature (May) 40C
Mean Minimum Temperature (January) 8C

temperature of -2.2°C was recorded on 31st January, 1905 and 16th January, 1964. The
surge in temperature starts from April and peaks in the month of June. The downward
trend in temperatures commences in September and continues up to January. The mean
annual rainfall is around 60 mm. Maximum rainfall is 198.8 mm which occurred in the
month of August in 2006. Rainfall increases from the month of June when thundering
activities start, and July and August are the rainiest months. Monsoon withdraws in the
middle of September. Rainfall decreases sharply in October and November.

IV. Energy Analysis Definition & Procedure
Definition
This report elaborates the current actual energy performance of the building and real-
time performance of all the energy intensive systems installed in the facility. Detailed
survey and testing of the energy intensive systems has been performed in order to arrive
at the present performance of each equipment. The test results have been carefully
analysed and presented along with improvement measures and general
recommendations for each of the systems. The suggested Energy Efficiency Measures
(EEMs) presented in the report are mainly of three types depending on their initial cost
implications – No Cost, Low Cost and Medium Cost measures. The measures, if
implemented, may help the facility team in optimizing the building operations and may
result in comprehensive energy and cost savings in the long run.

VIII. Energy Performance Index
Energy performance index (EPI) is total energy consumed in a building over a year
divided by total built up area in kWh/sqm/year and is considered as the simplest and
most relevant indicator to analyse the energy efficiency of a building.
The total energy kWh consumption by the facility includes the electricity consumption
from the grid supply and kWh generated by the DG. The total built-up area doesn’t include
the parking area.
Table 3- EPI Calculation (May 2019-April 2020) for Poornima University
Energy Performance Index (May 2019- April 2020)
Total Consumption (kWh) 1513474
Total Built up Area (m2) 26,471
EPI (kWh/m2/year) 57.17
The calculated Energy Performance Index (EPI) is 57.17 KWH/m2/year from May 2019-
April 2020.
As of now no specific BEE Rating or standard is available for the performance evaluation
of Educational Institutions, however, in case the suggested measures are implemented
the analysis team believes that the EPI of the whole campus can well reduce to efficient
standard.
IX. Renewable Energy
Solar The site has 100 kW solar roof top installed. Which provides an alternate clean source
of energy. It generates approximately 1, 50,000 kW of Electricity. It also provides shade
on roof hence reducing the heat gain.

and Daylighting Sensors 10%
An occupancy sensor is an indoor motion
detecting device used to detect the presence
of a person to automatically control lights or
temperature or ventilation systems.
2 ECM 2- Metering 5% -10% Will help in monitoring and logging
3 ECM 3 – Retrofitting lighting
and fan fixtures 25%
Retro fitting with low wattage LED’s and use
of efficient fans for the whole campus can
reduce the power consumption over this
end.
4 ECM 4 – Retrofitting of
Exterior Lighting 10%
Retrofitting with low wattage LED’s and
using reflective shading for reduction in
Night Pollution.

XI. Kitchen Inspection
It is generally observed that the installed stoves have a lot of carbon deposits around
the burners.

As a natural tendency flame and heat tend to
accumulate at the center. Efficient burners
regulate this natural tendency and spread
the flame evenly and uniformly across the
burner. Efficient burners are flameless,
smokeless and noiseless and produce
uniform heat just like charcoal heat.
2 ECM 2 – Biogas Plant
Bio gas plant can generate a green fuel that
can replace LPG and also offsets the
biodegradable waste efficiently.

XIII. Final Summary
D2O team has performed thorough energy analysis of the Poornima University. The
calculations were done using all the measurement taken at all energy consuming units at
the facility. The results obtained after the calculation were thoroughly observed. The
possible energy efficiency measures were given for the units to reduce the energy
consumption and to improve the overall energy efficiency of the facility building. The
energy efficiency measures given for each unit are summarized in the below table with
the investment, saving and return on investment quotient.
