Switching on to energy-saving methods will not only help the environment, but also the hotel's bottom line, as The Fairmont Dubai's Alka Patel explains.

Did you know that between 1971 and 2000 the world's energy consumption grew more rapidly than its population, with population increasing by 61% and energy use by 82%?

Between 1971 and 2000 the world’s energy consumption grew more rapidly than its population.

The Intergovernmental Panel on Climate Change, a group of several thousand independent scientists, states that pollution caused by human activity is unnaturally triggering the greenhouse effect, so that heat is being trapped near the Earth instead of escaping into space.

The result of this is known as global warming and climate change.

The main sources of climate change are the burning of fossil fuels (oil, coal and gas) to produce energy, and changes in land use, such as clearing of forest areas.

A light bulb may be a tiny consideration in global climate change, but consider the total impact of all light bulbs in your hotel or resort: lighting typically accounts for 15-25% of total electricity consumption in the average hotel.

When you replace light bulbs or entire fixtures in your hotel with energy efficient alternatives, you help preserve energy resources and reduce the risk of global warming, while reducing maintenance costs.

Energy efficient lights also produce less heat and therefore lower the demand on air conditioning systems. The greatest cost savings and the fastest payback records will occur in areas where lighting is constantly in use.

Did you know that a 13 watt compact fluorescent light emits the same brightness as a 60 watt incandescent, lasts about 10 times longer and uses 70 - 80% less energy than its incandescent alternative?

Replacing incandescent lights with fluorescent ones will save huge amounts of money. They have other advantages too, such as not getting as hot as incandescent bulbs in recessed light fixtures.

When buying replacement fluorescent tubes, ask for the special extra efficient type. A standard, 1.2 meter fluorescent tube uses 40 watts, while the energy efficient variety uses only 34 watts. That means another 15% saving on power costs and energy used.

While their initial cost is higher, compact fluorescent lights or CFLs will save an enormous amount of energy and money when compared with regular incandescent bulbs.

The average lifespan of one CFL is greater than the lifespan of nine incandescent lights. That means lower maintenance costs and less garbage in landfills.

An average CFL, over its lifespan, prevents nearly 200kg of coal from being burned, over 360kg of carbon dioxide and almost nine kilograms of sulfur dioxide from being produced and released into the atmosphere.

CFLs are more energy efficient and more versatile. They can be used with standard dimmer switches, standard photo sensors, electronic timers and occupancy sensors.

Their light is similar to soft white incandescent lamps and the medium size screw base allows for direct retrofit into existing incandescent fixtures.

Other considerations

Both single-piece and two-piece fluorescent bulbs may be slightly longer than standard incandescents.

Check before buying to make sure they will fit your fixtures.

It is important to remember that all fluorescent lamps contain mercury; the amount keeps decreasing as manufacturers make improvements, but the lamps are considered hazardous waste and must be disposed of carefully.

LED Lights

Lighting emitting diode, or LED, lights are becoming increasingly popular for decorative lighting and signage. When installed throughout a building, LED exit signs can save hundreds or even thousands of dollars in annual energy and maintenance costs.

One sign alone can save about AED 30 (US $8.17) annually on electricity costs and can last up to 10 years without a lamp replacement, compared to less than one year for an incandescent sign.
