What is the potential for energy efficiency improvement in hotels?

• More than 20% in most hotels

• Example: Hotel Arbol de Fuego

– Electricity savings = 39%

– Reduction in maximum demand = 42%

– Reduction in electricity costs = 59% = US$ 370 per room per

year

Lighting

Avoid using incandescent and halogen lamps

• Energy efficient lamps last longer and reduce energy consumption by more than 75%. These include:

– Fluorescent tubes

– Compact fluorescent (CFL)

– LED

• Example: Replacing a 50W halogen lamp with a 7W LED– Cost = US$ 30– Energy savings = US$ 130 over the 25,000-hour service life of the

LED lamp

A few recommendations for energy efficient lamps

• Buy quality

• Careful with light color when buying CFLs and LEDs

• When considering fluorescent lamps, keep in mind that fluorescent tubes outperform CFLs

• Careful with the handling and disposal of fluorescent lamps

• Give preference to LEDs

• Use incandescent lamps in areas with very low burn hours (<30 minutes/day)

Use efficient lighting fixturesInefficient fixtures can absorb more than 3/4 of the light produced by the lamp

Use light/reflective colors in spaces that frequently rely on artificial lighting

This white wall reflects 70% of the incident light

This green wall reflects only 14% of the incident light

• No matter how much light is provided in a dark colored room, the space will always feel like it is under lit

• Dark colored rooms require more light fixtures and/or higher wattage lamps

Take advantage of daylight• Sunlight is good for us and free

• In hot climates, be careful with overheating indoor spaces

• Direct sunlight = 100,000 lux (>200 times more light than needed for most tasks)

• Use indirect solar radiation

Use dimmers sparingly (if at all)

• Dimmable CFL and LED lamps are more expensive and harder to find, so many hotels install incandescent or halogen lamps on dimming circuits

• Dimmable switches are expensive

• Use them only where they are really necessary

Use a card key system or a master switch to control lights in guestrooms

• Ensure your card key system cannot be easily tricked

• Beware of sabotage by front desk or housekeeping staff

Air conditioning

Keep direct solar radiation out of air conditioned spaces

Shaded south-facing rooms

Exposed west-facing rooms

Shaded room. From 17:00 to 21:00, the ac unit runs 60% of

the time.

Exposed room. From 17:00 to 21:00, the ac unit runs

continuously.

Options to control direct solar radiations• Shading

– Can reduce solar heat gain by >80%

– Shading should ideally be on the outside

• Solar control film

Insulate and ventilate roof cavities above air conditioned spaces

• Temperature measurements conducted in an non-insulated roof cavity

Impact of reducing solar heat gain in a building through shading and insulation

Use reflective colors on walls and roofs that are exposed to direct solar radiation

Keep a reasonable temperature setting in air conditioned spaces (24 to 25C)

• Energy savings = 44%• Financial savings = US$ 6,000 /year

Other measures to reduce the energy consumption of air conditioning systems

Hot water

Use hot water efficiently

• Heating the water used in a 10-min shower requires 2.0 kWh of energy (approximately equivalent to running a guestroom light for 130 hours, or a guestroom ac unit for 4 hours)

• Efficient fixtures

– Showerhead ~8 L/min

– Bathroom tap ~5 L/min

– Work area tap ~8 L/min

• Efficient use of hot water presents huge opportunities of energy conservation
