Eco-responsibility doesn’t stop at the door of your house. People working spend an average of 200 days per year in their office or open space. And because it’s where people spend most of their time, hence the importance of implementing good practices there to respect our environment. Sources of pollution are diverse at work, between computers, mobility, air-conditioning…

Like at home, air conditioners are the biggest energy-consuming appliances in your work premise. It can make up almost 40% of electricity bills every month. That’s a lot of money spent to stay cool! Here are some tips to help you manage fresh air at work, and be your CFO’s hero.


Insulation is The Solution.

Insulation levels of your workplace are the first thing you need to check to save energy. With nothing more than proper insulation, most premises can cut their electricity bills by over 30%, by reducing the loss of freshness.

If your building pre-dates 1980, re-insulate. Only 20% of premises built before 1980 are well insulated. Have your management get advice from professionals to find the best insulation solutions.


Get Green Fingers.

If you are lucky enough to work in premises with an outdoor space, it means you can finally eat your durian with peace of mind, but also install plants in front of your windows, which will bring you shade and freshness. This is how to combine business with pleasure : grow your own pretty vegetables and that’s more freshness for your food!

Did you know that one tree produces as much freshness as 5 air conditioners? Besides, it consumes nothing.


Live Like a Vampire.

Glass surfaces bring ⅔ of the heat in your workplace. Handsome Jonathan is most likely the one who brings the other ⅓.

To avoid air conditioning and keep rooms cool in the office, install sun protection on windows - in the form of shutters, louvered shutters, blinds, awnings... Those placed outside are known to be more effective. Tint in your window could also help intercept solar energy that can heat the rooms.


Become a Fan Of The Fans.

Air conditioning is not only expensive, but also emits greenhouse gases (HFC and HCFC gases), with a global warming potential on average 1949 times greater than CO2.The electricity consumption of a fan is 20 times less than that of an air conditioner. A fan is thus a good way to cool down for a lower cost. Ceiling-mounted fans are particularly effective. On freestanding fans, place a damp cloth, to better spread freshness.


Choose The Right Temperature.

We know you can’t wait for wearing this new must-have cashmere sweater you've bought at Zara last weekend - so that Jonathan notices you. Yet, to save energy and reduce your contribution to global warming, better to turn on air-conditioning at 26°C inside the office.

If you change the temperature from 26°C to 25°C, you will increase the annual consumption of the appliance by 5 to 10%. About 3% of your company’s electricity bill will be saved for every 1 degree of the thermostat raised.

Besides, are you not tired of hearing everyday an orchestra of your colleagues’ sniffles in your open space? Not everyone is like a Polar Bear like Noel is.


Take A Breath.

Indoor air is on average 10 times more polluted than outside air. Most of us spend 22 hours out of 24 in enclosed or semi-enclosed spaces: office, house, transport, shops… Much less though is known of indoor air pollution.

The air we breathe at work go in through ventilation grids. Regularly cleaning them helps breathe healthier air, and better evacuate moisture.


Don’t Forget To Turn it Off.

To avoid wasting energy, turn the air conditioning unit off an hour before you leave your workplace, or ask your management to set up a timer system.

Numerous installations and applications allow remote management, which makes it possible to switch off the air conditioning in the absence of employees and switch it on one hour before their arrival, to maintain an ideal temperature to work.
