he main purpose of this report is to e?amine the ma?imum energy usage of the house. It isimportant to reduce the usage of electricity and amount of electricity 'ills to sa*e money and

electricity. So after all the e?aminations it is important to find the measures for energyreduction.

1.2 Scope:his report includes the e?amination of ma?imum energy consumption of apartment located

in )ooper %lains. ith the help of $u? meter and po#er meter the entire appliances andlighting in the house #as e?amined and data #as collected. "ence 'ecause of the issues of access to the po#er points some of assumptions #ere made in case of cooking sto*e o*enhot #ater system air conditioner and automatic garage door. Some of the main o'8ecti*es of the report are mentioned 'elo#:

)alculation of energy consumption and electricity 'illing of *arious appliances andlightning of house.

o figure out additional use of energy #ith the help of comparati*e analysis and todra# energy use patterns.

o find out energy measurement opportunity and also pro*ide somerecommendations.,*erall energy ad const sa*ing and ensuring less !"! emission.

1.3 Methodology:(nergy audit is an assessment of current energy;use practices in a proper manner. Itmeasures ho# energy is handled and consumed 0(nergy Sa*ings ool'o? A+n energy audit

or the measurement of the efficiency of the lighting lu? meter #as used that helps tomeasure the intensity of the illumination. $ight measurement and analysis is a crucial step

to#ards ensuring efficiency and safety. %o#er specification for lightning #as normallycolla'orated from the manufacturer specification. %o#er meter #as used to determine thepo#er usage and po#er factor of all appliances. or some appliance it #as hard to accessthe po#er points so po#er usage and po#er factor of such appliances #as taken frommanufacturer specification and from the #e'site of the manufacturer. Such appliances areair conditioner ,*en cooking sto*e and #ater heater. o ensure the accurate po#er consumption stand 'y usage of the de*ices #as also considered. (lectricity 'ills of last year #ere also used to get the usage trend and costing and #ere compared #ith the auditmeasurement to identify the difference. he use of total energy is di*ided into t#o *ariousseasons that are summer and #inter so it could 'e easy to measure the proper of usage of

cooling de*ices that are not 'eing used in #inter. (nergy audit steps #ere follo#ed asinstructed in the energy efficiency lecture notes #ith some ad8ustments #here needed.

1.4 Sources of Information and assumptions:he energy audit report consists from the assessment of different instruments #ith its po#er

consumption data analysis from the po#er meter manufacturerCs data daily seasonalusage a*erage running time and idle time. he energy audit report is also made 'y the helpof the lu? meters for lightning measurement and po#er meter for other appliances.

he use of different appliances may *ary according to time and seasons. he e?perimental

data #as measured during different time and pick uses and also po#er consumption atstand'y mode. he period of #hen the measurements #ere taken #as the March to +pril#hen the all instruments can 'e used for daily need. he certain assumptions #ere made#hen some instruments #ere hard to access through the measurement de*ice. heassumptions are made for appliances such as #ater heating pump cooking hot plate ceilingfans and garage door. he air;conditioning system is #orking on three phase high po#er consuming de*ices and due to direct connection #as gi*enD the data couldnCt 'e recorded 'ypo#er meter.

1.5 Site Issues:he house #hich #as chosen for energy audit is located at )oopers %lains Bris'ane. his

home has facilities of three 'edroom one 'athroom kitchen li*ing room dining roomlaundry and garage. he measurements of the many different instruments #ere taken 'utdue to lack of the other measuring de*ices it #as una'le to get readings of all instruments.Moreo*er some appliances are directly connected to the po#er source #ithout any po#er socket #hich #ere impossi'le to get measured. e# appliances cannot 'e measured'ecause of una'le to approach 'y measurement de*ices.
