Problem StatementProblem Statement
Due to the continuous availability of electricity at the Hotel, little or no
attention has been accorded to the energy use patterns of the hotel. The energy usage is very high and
accounting for approximately 10% of the operating cost of the entire
hotel

MethodologyMethodology
Research Design was quantitative. The audit process was divided into 3 phases;
1. History Documents Review- to establish a trend of energy consumption using utility bills. Evaluation of the building envelope.
2.

Walkthrough Energy Audit- was a tour of the facility checking the energy practices at the hotel. Then labeling according to estimated energy consumed.
Measurement Audit- with the aid of specific equipment as well as observation power ratings where recorded as specified by the manufacturer or when not available, tests where conducted.

Financial Benefit of OCMFinancial Benefit of OCM
Saving a average total of 55.982MWh a month represents 50.82% reduction.
The average energy bill will become approximately $6 174.63
This means energy costs will be 5% of the operating costs and even lower.
