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.

Brief

The Energy analysis was conducted by D2O team from 18th Aug 2020 to 22th Sept 2020,

at the University premises to study the existing practices of energy consumption and seek

possible ways to conserve water. The facility was introduced by, Mr. Simran Jeet.


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

Figure 2: Annual Daylight Hours (Monthly Mean) Source-NOAA


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.

ECM Description Savings

percentage Remarks

1 ECM 1 – Use of Occupancy

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.

ECM 1 – Replacement of

Existing Burner with efficient

ones

20%

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.
