Hi all,
i live in double storey terrace house.both floor equipped with a ceiling fan
currently im trying to turn my room at 2nd floor into a multimedia video game movie room.
i install kdk ceiling fan.
but the heat is unbearable,especially noon and also nite.
i cant afford to install air cond,and currently my house electric bill is still free,lol.
are there any way?kungfu? to make my 2nd floor as cold as my 1st floor?
exhaust fan? ventilation fan?will it work?
someone told me to put polisterine on the attic to stop the heat from coming down.
the logic is jus like polisterine box are being used to kept ice from melting.
will it work?

my room




Some of the findings from this thread
-Exhaust fan
-nippon solareflect
-wind turbine ventilation n air vent
-tinted windows/tinted film
-aluminium foil
-polisterine on roof
-awning/canopy
-water sprinkler
-ventilation fan on ceiling
-double layer brick wall
-tcl

Just get an aircond, u wont regret it.

i think because the heat generate during daylight will release to top during night time, that's why top floor hotter than ground floor.sum more top floor close to roof/ceiling. open the windows, let the hot air go out, but usually brick house is like this compare to wood, as they store heat more compare to wood

my 2 cents (^__^)

there's no kung fu to cool your room, only aircon

big lcdtv + cpu will generate extra heat...
need to be aircond room to solve it..

yea, agree that you should get air-con for the long run.
remember, all the electronic equipments in the room wear out faster if the room is too hot.

I believe it's hot because one of the wall face sunlight during afternoon to evening. Heat trap in the wall will be released at night.

Have ventilation, use a suction fan to suck out hot air. Ventilation fan does not use much electric as air con.

if you have money to invest. The best bet will be an insulator. I got a contractor to build this some time ago.

On the wall that face sun light, they assembled a frame consisting of made of wood laid vertically. aluminium can be use as well. In the empty spaces, heat insulator can be placed. if not leave empty, air also can act as an insulator. Before you put up the wooded / gypsum / artificial concrete. You can have additional heat reflector pasted at the board facing inside to reflect heat.

Last time i did not do both heat reflector / physical insulator. Still the temperature reduce to an acceptable range.

The greenest way. Grow a tree to block of the afternoon sunlight.

If you were to put aircond do not put at the wall facing the afternoon sunlight. avoid placing the compressor at the same wall too,

Good luck!

You can contact Roxul. They have a system to cold 5 deg down.

Thermal insulation is critical as the heat will not go away. I installed insulation material and I could take nap in the afternoon with the moderate fan on.

To be really effective, laminate window film to window too.

Thermal Foil insulation.

thanks bro

how bout take cold shower b4 u sleep

hang some wet cloths in your room...

open your room door , dont close it...

Dun know what it is called but I call it a canopy. Install it outside ur window. It helps to keep the sunlight out of ur room during the day. cheap solution.

It shows that your roof is badly insulated. Your condition is same as mine, mine is three storey house, The top floor is super hot in the afternoon, the living room is probably 2-3c colder than the top floor. You can practically feel the difference in temperature, downstairs and upstairs. It's like walking into a sauna room in the afternoon.

alrdy tried bro,lol.doesnt work

can try install a turbine ventilator..

to extract the heat out from the space between ur ceiling and roof

or install a ceiling ventilation fan to remove the warm air from the room and keep a circulation of air to keep the temp down..

air from bottom house raise up due to the ceiling ventilation fan and the air is extracted to the ceiling and the turbine ventilator take the hot air out from the attic/space between ceiling and roof...

u want better install thermal insulation material.. and if got some extra money to spend around wash and repaint the roof to white/silver shade..

maybe what you can do is to get ventilation holes for your wall (the lower the better, then get electric ceiling ventilation fans..... then have your roof install the "mushroom" thingy....

install air-con and start pay the bill..lol

ur problem is same with me but my ground floor most hot than 2nd floor.. i still cant find the problem why my ground floor toilet is too hotttttt.. what wrong with our ozone now?

My dad solved the ground floor hot toilet by adding a ventilation fan on the wall to extract the hot air out to kitchen. It helps....

Added on June 7, 2011, 7:47 pmThe room is hot bcos the heat transmit from roof and trap in ceiling, when you on the ceiling fan, it puss the hot air downwards. Also, there are more heat come in from the window if your window is facing west.

Thermal insulation on the ceiling + tint on window. Open window when the outdoor ambient is cooler for natural ventilation.

I think akmis is 100% correct. Heat is from your side wall, ceiling is not so bad assuming you have concrete roof tile.

Insulate yr wall, outside cannot ( for link terrace ) then do inside. Not much choice other than AC.
