Energy cost is around 7.54% of the turnover
5. Observations
Main energy sources are electricity, diesel and
LPG
All hotels use DGs during load shedding
Laundry service is installed only in big hotels
Lights mostly switched to CFL
High cost of electrical energy from DG
Performance of equipment not checked
Energy audit not carried out
6. Saving Potentials
Saving potentials from ESPS audits,
= 45.24% of electrical + 16.18% of thermal
energy
The electrical saving potential will be
= 0.4524*34946835 kWh
= 15,810 MWh
The thermal energy saving potential will be
= 0.1618*91504653 MJ
= 14,805.453 GJ

8. Energy Benchmarks for Hotels
It is complex for Hotels. Niki Hendrikx, 2008, gives the
following energy benchmarks for the hotel sector:
Hotel Type Fuel (kWh/m2*yr) Elect (kWh/m2*yr)
Mean Max Min Mean Max Min
Small & medium without
complete A/C

11. Areas of Potential Savings
Improvement in lighting system and use of daylight.
Improvement in air conditioning
Improvement in refrigeration and deep freezers
Power factor and Load management
Improvement in combustion efficiency in boilers and hot
water generators
Insulation of the hot water supply pipes
Conversion of waste to energy (Methane from bio-
decomposable waste)
