Energy conservation study at Hotel Soaltee Crowne Plaza ...

Executive summary
� Total energy consumption in common unit in hotel is approximately 12 357 410
kWh (kilowatt-hour) or 33 856 kWh/day.
� Electricity accounts for 47%, kerosene for 46%, and LPG (liquefied petroleum
gas) shares seven per cent of the total energy consumption.
� Approximately 1 650 000 kWh (4520 kWh/day) energy is consumed in lighting
systems.
� Annual consumption in an air conditioning system is around 1 024 651 kWh or
3730 kWh/day.
� The total annual energy cost is approximately 49.3 million rupees (135 000
rupees/day).
� Electricity accounts for 77%, kerosene for 19%, LPG for two per cent and HSD
(high speed diesel) for two per cent of the total energy cost.
� EUI (energy utilization index), defined as total energy consumed divided by total
built-up area (kWh/m2 ) at Soaltee Crowne Plaza, Kathmandu, is 434. EUI is used
to compare the energy efficiency of two similar types of buildings. The other way
to represent EUI is kWh/room/day and this is found to be 113 at Soaltee.
� Replacement of underloaded motors with appropriately sized motors could save
56 720 kWh or 404 700 rupees annually. This would require an initial investment
of 341 120 rupees (without including the salvage value of the replaced motors).
� By proper loading of transformers, there exists a potential to save 83 000 rupees
annually without expending any money.
� Replacement of V belt with flat belts in 10 motors can yield a saving of 70 900
rupees annually at an initial investment of 37 800 rupees.
� By improving the lighting system efficiency with the use of more efficient lamps,
luminaries, and ballasts, there exists a potential to save 588 400 kWh in a year or
4 177 650 rupees. Retrofitting would require an initial investment of 3 427 800
rupees, with an average payback period of just 10 months.
