Energy Audit:

2. Introduction:Home energy audit is assessment of home energy. This is a first step that helps to check

how much energy any house consumes and after evaluation required solution can be find to

make the house more energy efficient. (ustin !ulvaney " #aul $obbins% &') .*t includes

evaluating the actual utili+ation of electrical energy and solutions of conservation of energy.

Energy Audit helps to know about the areas where energy is wasted a lot and where

improvements can be done to save energy. (,i-o alakrishnan%Arya/rishnana. #&%% ,oice

,oy0%1ibin /.1% $eshma 2handran3% &'4). A successful auditing -ob should make known to

the proprietor or administration team of the structure related to the options present for less

energy waste% involvement of the prices% and the advantages achievable from relating those

energy5management opportunities. (edwards% &''4)

2.1 Background:To make the report of energy audit% an apartment in 6&3 oundary $oad 277#E$8 #9A*18

9 ;'< was investigated. This house is appro=imately more than &' years old. This

apartment consists of three bedrooms% one bathroom% a kitchen% a living room% dining room%

a laundry and a garage. The number of residents in this house is two. The average electricity

bill of the apartment for last year is >33' for period of 6' days. According to the number of

people who are living in the property the usage of electricity and amount of power bills is so

high.

The main purpose of this report is to e=amine the ma=imum energy usage of the house. *t is

important to reduce the usage of electricity and amount of electricity bills to save money and

electricity. 8o% after all the e=aminations it is important to find the measures for energy

reduction.

2.2 Scope:This report includes the e=amination of ma=imum energy consumption of apartment located

in 2ooper #lains. ?ith the help of 9u= meter and power meter the entire appliances and

lighting in the house was e=amined and data was collected. Hence% because of the issues of

access to the power points% some of assumptions were made in case of cooking stove% oven%

hot water system% air conditioner and automatic garage door. 8ome of the main ob-ectives of

the report are mentioned below:

2alculation of energy consumption and electricity billing of various appliances and

lightning of house. To figure out additional use of energy with the help of comparative analysis and to

draw energy use patterns. To find out energy measurement opportunity and also provide some

recommendations.

7verall energy ad const saving and ensuring less @H@ emission.

2.3 Methodology:Energy audit is an assessment of current energy5use practices in a proper manner. *t

measures how energy is handled and consumed (Energy 8avings Toolbo= An energy audit

tool and manual) Two tools #ower meter and 9u= meter were used to take all the reading for

the audit.

Bor the measurement of the efficiency of the lighting lu= meter was used% that helps to

measure the intensity of the illumination. 9ight measurement and analysis is a crucial step

towards ensuring efficiency and safety. #ower specification for lightning was normally

collaborated from the manufacturer specification. #ower meter was used to determine the

power usage and power factor of all appliances. Bor some appliance it was hard to access

the power points% so power usage and power factor of such appliances was taken from

manufacturer specification and from the website of the manufacturer. 8uch appliances are

air conditioner% 7ven% cooking stove and water heater. To ensure the accurate power

consumption% stand by usage of the devices was also considered. Electricity bills of last year

were also used to get the usage trend and costing and were compared with the auditmeasurement to identify the difference. The use of total energy is divided into two various

seasons that are summer and winter% so it could be easy to measure the proper of usage of

cooling devices that are not being used in winter. Energy audit steps were followed as

instructed in the energy efficiency lecture notes with some ad-ustments where needed.

3. he site:The report of the energy audit is done for a three bedroom house situated in 2ooper #lains

that is appro=imately &' years old but it has been refurnished recently with some new

appliances. This house consists of three large si+e bedroomsC each bedroom has at least

two power point% one bathroom% a living room% laundry% a study and a garage. The number of

people living in this apartment is two and both are adults.

3.1 !eneral description of the main appliances:There are number of electrical appliances in the house and that are further divided into two

categories. Birst are the high consuming devices like Air conditioning system% Dacuum% iron

and washing machines. The other is low power consumer devices such as phone charger%

laptop% hair straighter% fans% and lights etcetera.

Al l devices have their own operational time like refrigerator it operates &;F in the house and

iron that is rarely used but consumed a huge amount of electricity even in the standing

mode. 8ome of the high operational time devices are free+ers% router% lights% fans% andtelevision. A few of the devices are low operational time are washing machine% hair dryer%

vacuum and sandwich maker. *n everyday life most of the appliances that are used in the

house are appliance of kitchen that consume most of the energy like refrigerator% microwave%

oven% dishwasher% sandwich maker% food processor and hand grinder. uring weekdays

normally in the morning most of the appliances are switched off because no one stays at

home in the mornings% e=cept some stand by appliances. !oreover% these stands by

appliances also need to be considered% whose power consumption cannot be ignored.

?hereas% there are some lights and appliances that continuously run in evening everyday

like lights of lobby and appliances such as Televisions and setup bo=% fan and sound bar.

There is also some stand by devices which draws a small amount of power. 8ome e=amples

of stand by devices are automatic door garage% TD% laptops% printer% setup bo= etcetera.

3.2 "eating and cooling:7n average most of the energy% appro=imately ;' percent of the energy used at home is for

heating and cooling. The amount of energy is depending on the circumstances and climate.

(Gour energy saving% &'4)

This site has ma-or cooling appliance that is air conditioner. There are two air conditioners in

this houseC one is in lobby that is..... and other is in the main bed room. oth the air5

conditioned normally used in the season on summerC especially in the afternoons that is the

hottest part of the day in the summer season. 8ometime in the winter days% during theafternoon air conditioner runs in the house. The air conditioner of the main bedroom runs

almost every night of the summer season. This house has reverse cycle air conditioners% as

it helps to increase the efficiency by 3 to 3. (Gour energy saving%
