4. Sector Highlight
 Hotel basic infrastructure for Tourism Industry
 Tourists increased by 18.21% in 2009/10 compared to
previous year
 Average stay increased to 12.67 days from previous 11.32
 According to HAN, hotel industry grown by 15%

Energy cost is around 7.54% of the turnover

6. 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

7. 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

9. 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 238 286 196 77 80 71
