Cresta Jameson Hotel.Cresta Jameson Hotel.

IntroductionIntroduction

A 3 star Hotel in the CBD of Harare.Host to 123 Guest Rooms, 5 conference centers,

2 magnanimous Kitchens, 3 Restaurants and a Banqueting Lounge.

Electricity charges are at an average $12 350/month.

Hotels are bracing for brisk business and therefore will do anything to increase profit and increase the quality of stay.

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

AimAim

To carry out an energy audit and analyze energy management opportunities at Cresta Jameson Hotel

ObjectivesObjectives

To carry out an energy audit at Jameson Hotel;

Devise strategies and methods to increase the energy efficiency at Jameson Hotel based on the results of the audit.

Carry out an cost benefit analysis of the methods suggested.

Justification of the StudyJustification of the Study

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.

LimitationsLimitations

Time Constraints since a huge project requires

longer periods.

Cash Constraints for travelling to and from

Harare.

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.

Methodology…..ctdMethodology…..ctd

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.

RefrigerationRefrigeration

Use of strip curtains or plastic swing doors on cold stores;

Making sure that the doors of the cold stores are shut all the time;

Door Gaskets should be checked fortnightly;Use of CFL’s or LED lights and should be

switched off when closed;Refrigerators should not be overloaded.

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.

Conclusion and Recommendations Conclusion and Recommendations

Conclusions1. There is a huge potential in savings of even

more than 50.8% and therefore should be considered;

Recommendations Recommendations

Establishment of an Energy Management Team.Further research on Solar CoolingFurther research on Refrigeration.
