We generally spend more time in the office than at home. For eco-friendly people, some good practices at work are necessary. But how to implement them?

Very simple ones can be adopted without representing a constraint for your colleagues and management, starting with the lighting.

Light pollution washes out starlight, interferes with astronomical research and disrupts ecosystems. In 2016, Singapore was named the country with the worst level of light pollution in the world - with a pollution level of 100%.

Working By Night is Not Eco-Friendly.

What is the use of lighting a desk with a lamp, when there is a window in the room? Place your desk close to windows or natural light sources, to avoid using electricity for lighting your office during the day. Encouraging the use of natural light means saving energy, and money for sure: lighting contributes to about 30% of the electric bill for a typical office. A good excuse to come back home earlier, before dark!


Break Up With Halogen Lamps.

At home and in your workplace, halogen lamps consume a great deal of electricity and generate a lot of heat. A halogen lamp switched on for 3 hours consumes 350 watts, the equivalent of 23 low energy bulbs. To save electricity, permanently replace halogen lamps with LEDs or low-energy lamps. Singapore is hot enough!


Save Energy With Low Energy Bulbs (Is It Obvious?).

Low energy light bulbs consume 5 times less energy and last 15 times longer than incandescent bulbs. Choose the most energy-saving light bulbs, adapted to the place you want to light. For instance, a 20W low energy lamp is suitable for reading or working, but one of 5W is sufficient for sharing gossips in the toilets.


Automatic Magic.

Like clockwork, so are lights. Out of habit, if you find that you frequently turn on lights between certain hours, automate that process with timer lamps. For common areas that aren’t frequented all the time, explore the use of motion detectors to trigger the lights on/off. This would save you electricity in the long run, especially when they don’t need to run all the time.



Low energy light bulbs are hazardous waste. They contain a few milligrams of mercury, highly polluting and toxic to health and the environment. Besides, they are 93% recyclable. Bring them to the store where you bought them, it should have a light bulb collection point. Never throw them in the garbage bin!


Lead Them To LEDs.  

LED bulbs are light-emitting diodes. A light-emitting diode lets the power flow only in one direction. One-way, like when Giselle tries to flirt with Jonathan.These LED bulbs last 20,000 to 50,000 hours, compared to 5,000 to 15,000 hours for low-energy bulbs, and 1,000 hours for incandescent bulbs. Thus, they allow considerable energy savings, consuming an average of 0.06 W per bulb!


Turn Off The Lights.

Turning off the lights when you leave a room is an eco-gesture that may seem simple and obvious, but that enables to save significant energy as a daily reflex: 10 minutes of unnecessary lighting three times a day is equivalent to five days of continuous lighting after one year.This systematic reflex has to be assimilated by all your colleagues. However, if Nicole could avoid turning off the light when people are in the toilet cubicle…
