ENERGY: Faircity Hotel Group Achieves a 169.567MWh Reduction in Electricity Consumption Across Four Gauteng Hotels

 





Recent Gauteng Business News

The Faircity Hotel Group, a vibrant and innovative hospitality company with properties in the three and four star categories, worked with an Energy Services Company (ESCo) to conduct a lighting energy usage assessment at the four hotels.

Lukas van der Westhuizen, Managing Director of Faircity Hotels says the move to optimise the efficiency of lighting technologies was prompted by the need to reduce energy costs, lower operating costs and advance towards reducing the group’s carbon footprint.

Some 7 353 energy intensive lamps were removed in the four hotels in less than a month:

In public areas –

50W halogen downlights were replaced with 7W LEDs (Light Emitting Diodes);
35W halogen downlights with 5W LEDs;
60W incandescent bulbs with 7W LEDs; and
100W incandescent bulbs with 10W LEDs.

In rooms and staff areas –
50W halogen downlights were replaced with 7W LEDs (Light Emitting Diodes);
35W halogen downlights with 5W LEDs;
60W incandescent bulbs with 7W LEDs; and
100W incandescent bulbs with 10W LEDs.

LEDs were chosen for their energy efficiency but also because they produce a colour temperature comparable to incandescent bulbs and give off a similar warm yellow glow. Colour temperature plays a crucial role in how people perceive colour and experience thermal comfort, two important considerations in the context of the ‘home-from-home’ expectations of hotel guests, Lukas says.

Aside from using approximately 85% less energy than incandescent lamps, LEDs last up to five times longer than CFLs (Compact Fluorescent Lamps), which last about 6 times longer than incandescent bulbs.

Moreover, LEDs have a quick start up time, produce their full light capacity as soon as they are switched on and turn off immediately without any fading as the bulb cools down.
The four hotels also replaced energy intensive T8 fluorescent tubes with energy efficient T5 tubes.
Outside, HID floodlights were switched to LED floodlights.

In addition to saving electricity, the lighting retrofit also helped the Faircity Hotels Group to make positive strides towards reducing their carbon emissions, an increasingly important consideration for environmentally aware national and international travelers.

By reducing energy consumption from 195.199MWh to 25.632MWh per month, the four hotels have reduced their carbon emissions from 193.247 to 25.376 tons per month and saved approximately 232.307 kilolitres of water per month from being lost to the electricity producing process.
“Faircity goes to show that a lighting retrofit, relatively quick and easy to implement, can reap impressive energy efficiency results. Lighting is often one of the most overlooked low-cost opportunities for reducing electricity consumption in hospitality establishments without impacting the guest experience,” comments Andrew Etzinger, Senior General Manager of Eskom’s Integrated Demand Management (IDM) department.
