Ideas for reducing heat in school?

[Sun_2010]

The onus is on the ministry to choose right ideas and implement.

If they fail to do that :nunchuk:
- yeah, we get to excercise collective wisdom 5 years later.

SAHM_TAN, don't worry, I :hugs: you...


I agree it is an environmental issue indeed.
However, I learn to see that we cannot solve world issues, so we start with baby steps solving home issues first, hopefully along the way contribute to solving world issues.

Thanks for the :hugs:

[quote=\"ksi\"]......7. Get sponsorship from drinks like Milo to make rounds to schools to give cold Milo or ice-cream vendors to provide mini ice-cream relief....mini \"sng pao\" is good........

and when some kids start coughing, the parents may blame the school or even the Minister of Education.

Tankee, when we were young, we also ate sng pao, drank cold milo and ate heaps of ice-cream but never fell sick(of course no air-con then too)...... so this problem is more than the school or MOE....it's basically the state of not-so-strong health the kids are these days.

Ah I think we should direct to MOH instead to go to the root of the problem!! :lol:[/quote] wah..u so heng!..my time..where got cold milo...remember only got 'milk' only leh.. Our kids these days consumed food which is mostly genetically modified..chemical ..add...add..look at that the recent china MELON :mad: :rant:

Some of your comments really crack me up!


I ‘Kee Chiu’ to the following:

1) Allow flexibility of wearing PE attires on hot days
2) Having more greenery around the school and within the premises, including classrooms. (Growing creepers also helps cut down wall temperature.)
3) Making 'sng bao', ice milos available on hot days (when temp. exceeds 30 degrees, for example), or providing free ‘liang teh’ during recess
4) Giving ‘water’ breaks –encourage more intake of fluid
5) Reducing class size
6) V-cool glass windows
6) Redesigning using environmentally friendly materials & structures (this should be new requirements for new schools/schools planning for upgrading and new HDB flats)

Apart from these, Funx3 mentioned about sleeping in class, which I think is interesting - 夏日炎炎真好眠 － cos sleeping does lower the body temperature.

Like the way we use day blinds at home to block out the heat from the windows, schools can consider installing day blinds for classrooms that may experience direct sun.(They prob. already have? I haven't noticed any in my son's school though) This should keep classroom temp. to below 30 degrees.

Students can take turns using wet cloth to wipe their own desk – 40 students means 40 desks, that’s a pretty big surface area for evaporation, maybe even pass the mop around so they can mop the floor around them (so they don’t end up perspiring even more). With air circulation from ceiling fan, the air should become cooler. Placing a basin of cold water near the fan might also help (but maybe not so practical if the kids tip it :roll: )

Giving “Freshen up” time – kids can bring along a face/hand towel to have a rub-down bath (on face, neck and arms).

There is a method of mixing alcohol with water - 1:9 and spray the mixture into the air. Temperature is reduced due to evaporation, but the alcohol absorbs surrounding heat faster than water, hence helps to reduce temperature more rapidly – haven’t tried this method myself though.

Genetically modified... :rotflmao:


Modified my DD1 into a balloon with all that Mac Donalds.

Agree with ksi on the teeny bb steps.. :celebrate:

And yes... hugs for SAHM_TAN... :hugs:... even if she's the anti-aircon. :lol:

:lol: :lol: like the anti-aircon :lol: :lol: someday maybe not today or tmr but someday, the hubby and then the world will know that I'm right :lol: then fading :lol:

Back to being serious, I think natural way is the best way

[buds]

True… natural way wudn be sufferingly hot now if everyone protected nature’s way

from the beginning. Oh well… just like how we can’t force parents to un-kiasu
themselves… likewise for this. We can’t possibly turn all the pro-aircon blues
to the anti-aircon greens. That said tho… it has been terribly hot la. Some
rain out at my plc last 15 minutes helped a bit. DD went swimming with
gramps earlier, bet she’s cool there just now. I can’t follow cos buds_
chubs fell ill… his first flu.

Why don't like the air-con? I thought even MM also sez air-con is the greatest invention of modern history.


The fact is, to get a really eco-friendly system to enable passive cooling for schools, it is probably necessary to practically tear down and rebuild the schools from ground up to be designed as naturally heat resistent structures. Placing heat resistent films on windows, building air-wells, solar cells, etc, could end up costing more than just setting up air-cons for all schools.

Oh dear....take care of yourself too. I remembered when my bb and when her siblings were bbies, running nose and fever are really difficult. I will hold them sleeping in upright position so that they can breathe easier
