Today is Blog Action Day,
"On October 15th, bloggers around the web will unite to put a single important issue on everyone's mind - the environment." - I learnt of it too late so I haven't got anything to put on but I got this off another blog, it's about the vicious cycle of airconditioning. It's a good read and I'd like to share this with all of you, my friends. Do take some time to look through it. I hope this will inspire everyone to make the effort to at least turn up the temperature a bit.
Air Conditioning- Boon or Bane?
It is worth pointing out that comfort, Singapore style, is not seen in egalitarian terms. Air- Conditioning is a selfish technology: one of its paradoxes is that its net effect is an increase in heat. As a prodigious consumer of energy- it accounts for one-third of Singapore's electricity use- it contributes significantly to global warming.
Cherian George - Singapore The Air-Conditioned Nation
Here is a dilemma for us in Singapore. Our dependency or air-conditioning is already enormous & apparently still growing. In 1988 less than a fifth of households had air-conditioning. By 1997 more than half had air-cons & by 2003 the figure is more than 70% of households in Singapore. However, if that is any consolation, we still rank below Japan which has the highest air-con ownership in Asia. On the other hand in China, Vietnam, India & any other Asian countries it is still less than 1% of all households.
So is the air-conditioner a luxury, an aspirational symbol or a necessity?
When I was young air-conditioning was considered a luxury that few people enjoyed. Certainly, although I came from a relatively affluent background, I did not sleep, study or travel in air-conditioning. When we were hot we had a big glass of ice water-already a luxury- or used fans.
Today, most of us are used to working, traveling, studying & playing in air-conditioning. Even some of our streets are now air-conditioned. Certainly, on hot muggy days I am inclined to agree with M.M. Lee Kuan Yew when he said that air-conditioning was the greatest discovery of the millennium. All of us have experienced the exquisite sensation of coolness on entering an air-conditioned room or the greater productivity of working/studying in an air-conditioned environment. But that was before global warming became the hot topic it is today. We know now that using more air-conditioning adds to the warming of the earth which will mean more hot days with more demand for air-conditioning.
So do we have to forgo the comfort of air-conditioning if we are to become carbon neutral? Or are those of us who can't give up the addiction to feel guilty about enjoying air-conditioning? I feel that there is a lot we could do to reduce our dependency & still enjoy the benefits of cooler air. Here are some observations for your comments.
-Did you know that a study done at NUS by Leow Kim Guan for his M.A. thesis showed that when subjects( all Singaporeans) were allowed to adjust the room temperature every 10 minutes their preferred temperature of optimum comfort was 25.4 degrees C? How many thermostats in Singapore are set at that temperature here?
-Why do we continue to dress for colder climes - ties, jackets, suits, pashminas-when we would be much more comfortable & environmentally sustainable in tropical garb? Is it really comfort or unthinking bad habit?
-My daughter could not bear the freezing temperatures in her lecture halls in JC despie her thick jacket. She said she couldn't think for shivering . She is now in Boston where she is well-known for her high level of tolerance for cold which everyone finds surprising for someone from the tropics. Perhaps she was conditioned by Singapore air-conditioning.
-A visiting environmental lawyer from the World Bank was appalled when she tried unsuccessfully to increase the thermostat setting in her freezingly cold hotel room & was told by the staff that it couldn't be done because that was the norm for 5- star hotels i.e a choice between very cold, freezing & arctic (except that global warming is resulting in the arctic being less cold ).
-Should bus drivers be allowed to keep the air-conditioning running when they are the sole occupants of their buses parked in nature areas such as the Botanic Gardens or Sungei Buloh where visitors who go to enjoy the outdoors have to breath in large lungfuls of their fumes & hot air instead of the fresh air which we go to enjoy?
-Did you know that Inuka, the Singapore-born polar bear at the zoo does not have air-conditioning in his enclosure? The authorities say he is acclimatized even though, unlike us, he has no sweat glands & has fur that is specially adapted to retain heat. Well if he can survive & remain active in Singapore without air-conditioning I think the rest of us could make more of an effort to live without air-conditioning-or less air-conditioning to begin with.
