Sector Highlights

Hotels are basic infrastructural facility needed for the tourism industry. The tourism sector of Nepal is recognized to be an important pillar of the countries' economy. Nepal's tourism industry earned US$ 330 million in 2010 and was one of the highest contributors of foreign exchange reserves. A total number of 789 hotels are providing 30,042 beds for hospitality.

Hotels use both electrical energy and thermal energy to provide services to its guests. Main energy sources of hotels are electricity, diesel and liquefied petroleum gas (LPG). Electricity is supplied to the hotels by Nepal Electricity Authority (NEA). However, due to increasing power outage most hotel have their own diesel-powered backup system for electricity. Diesel and LPG supplied through Nepal Oil Corporation (NOC) is the major source of thermal energy to the hotel industries of Nepal.

According to Hotel Association of Nepal (HAN) business in the hotel industry has grown by nearly 15% in the fiscal year 2009/10 as compared to previous years. The hotel industry is considered to have the highest local private sector investment in Nepal with a recorded investment of around Rs 100 billion. HAN has under its umbrella, 8 five-star, 3 four-star, 12 three-star, 22 two-star and 18 one-star hotels and 165 non-star, four allied and 33 resorts.

The numbers of star and non-star hotel have steadily increased during the last year (see table below). As per data from 2010 there are 103 star-rated and 686 non-star hotels providing a total number of 30,042 bed to Nepal's visitor.

Energy use

Main sources of energy used in the hotels in Nepal are electricity, diesel oil, LPG and rice husk in some of the hotels. Diesel oil and rice husk is used for generation of steam or hot water. LPG is used in the kitchen for cooking purposes and electricity is used mainly for operation of refrigeration & air conditioning system, lifts and lighting. Approximate share of electrical and thermal energy used in a typical star-rated hotel is presented below. One can see that electricity has with almost 60 % the highest share of energy consumption followed by Diesel (25 %) and LPG (12 %).

Baseline study undertaken by NEEP/GIZ in 2011 for the hotel sector has found the specific energy consumption by hotel Industries as illustrated in the table below:

Energy Saving Potential

The hotels sector stands on rank 6 among the most energy-intensive industrial sectors in Nepal. Hotels spend almost 8 % of their turnover for energy cost (GIZ/NEEP, 2012). Most hotels have switched from conventional lighting to more efficient CFL and about 10 % are already using most-efficient LED technology. However, 90% of surveyed hotels have neither checked the performance of major energy consuming equipment nor carried out energy audits in their hotels.

Figure 1: Energy cost on product value in % for different industrial sectors in Nepal (GIZ/NEEP, 2012).

GIZ/NEEP baseline survey (2012) estimated the electricity saving potential of Nepalese hotels to be about 30,000 MWh which is equivalent to the annual consumption of about 84,000 households in Nepal. On the thermal side Diesel consumption could be reduced by 200,000 Litre and LPG by 91,000 kg per year. In total Nepal's hotel sector could save about 360 Million NPR every year by implementing most common energy efficiency measures.

Figure 2: Monetary Saving Potential in Nepalese Hotel Sector (GIZ/NEEP, 2012)

Practical experiences show that many options are feasible and cost-effective. For example Annapurna Hotel in Kathmandu installed double glazing in 90 Deluxe category rooms which reduced drastically the sound pollution to the room occupants and at the same time heating and cooling load was reduced by 8-12%. After replacing the garden lighting of seven halogen lights with energy efficient LED and CFL technology they could also reduce energy cost by more than 1,00,000 NPR per year. All rooms of Annapurna are equipped with card-activated occupancy sensors which cut-off the power of all electrical appliances and lights two minutes after the guest has left the room; the saving in electricity was approximately 25–30%.

Experience from the past have identified many options for improving energy efficiency in hotels that are highly profitable, most of them with payback periods of investment of less than 1 year. The following table shows some implemented example options in Nepalese hotel sector with the respected payback (Danida/ESPS, 2005).

Table 1: Energy saving options in hotels and payback period (Danida/ESPS, 2005)

Renewable energy technologies can also help hotels to reduce energy cost: Since more than two years Hotel Barahi in Pokhara is running a biogas plant that converts all kitchen waste and sewage into cooking gas. The construction of the biogas plant cost only Rs 6,00,000 and can produce enough gas to power a stove for five to eight hours a day providing food for hotel guests and 100 staff. The installation of biogas plants for kitchen and sewage waste in Hotels has an average payback period of only six month (IFC, 2012). Solar thermal collectors are also appropriate for hotels for water heating as well as space heating. Good quality technology is available on the Nepalese market and cost effective with payback of investment between six to nine months. Even Solar PV Panels are applicable in Hotels. Annapurna hotel has installed nine highly efficient LED light panels of 28 Watts each which are powered by pure PV Solar system that can power the lights for three days.

Energy Saving Tips

The main areas to tap energy saving potentials in Hotels are lighting, housekeeping, boiler, hot-water and electrical systems as well as HVAC. The installation of renewable energy technologies might also considerably reduce energy cost in hotel operation.

Table 2: Recommended lighting levels for hotels

Figure 1: Comparison of different lighting technologies

Lighting

  • Use of day lighting wherever is possible.
  • Lighting levels should be up to recommended standards
  • Replacement of inefficient incandescent light bulbs for CFL and consider switching to most-efficient LED lighting technology
  • Installation of occupancy sensors and/or timers for areas that are less frequently used such as hallways, outdoor areas, or public bathrooms
  • Optimization of Lighting System voltage

Housekeeping

  • Install a key-activated Guest Room Energy Management System (GREMS) to control lighting, heating and cooling inside the rooms.
  • Improvement of fuel storage and handling system
  • Use of energy-efficient refrigerators and deep freezers
  • Sealing of windows to optimum tightness or replacement of single glazing through double glazing windows to reduce heat or cooling loss in air-conditioned rooms

Boiler and hot water system

  • Application of Combustion Gas Analyzer for combustion analysis and combustion tuning of boilers or hot air generators.
  • Installation/maintenance of Steam Traps
  • Optimization of Steam Distribution System (Steam Traps, Piping, Headers)
  • Insulation of Flanges and Valves with Insulation Jackets
