insulate the roof
install the air ventilator

I see... Can follow best practices, no need UBBL to tell minimum opening must be 10% of flooor space.

I blame greed. Profit over everything else.

Modern design suka pakai glass that is y hot + floor quality they like to give u shit quality.

If houses don't trap heat, how TNB want untung atas angin ?

Ang Moh house use big glass to replace wall…. Malaysia also follow…. last last waste more money for curtains……. Too HOT

R value, wrong material in wrong design. End up use more energy to cool off

meanwhile me staying in shoebox flat high-rise very cooling no aircond needed

Ang moh’s glass all double glazed with low U value and SHGC.

Here we use normal glass not knowing how much heat it brings in lel

msia electric too cheap

Put up glasswool or rockwool insulation beneath the roof, and support the insulation with woven aluminium sheet.

I spend rm6k for the entire roof insulation, and now paying around rm150 for electricity.
5 aircond, 5 toilets, 1 garage full of high powered tools

more holes/more windows = dust. especially if your house is facing busy road.

if you have air vent on the roof, proper placement has to be made to prevent rain coming inside.

i have 4 turbine ventilator on my roof, my house just feel not that hot.

If your house hot and also got high electricity bills, use solar panel. Reduce some heat go to inside your house.

Boleh kan?

modern problems require modern solution,

Yes, that is correct

Reduce heat buildup between the roof n ceiling

Ya ktard what also expert...terrorism expert, military expert, geopolitical expert + driving mercedes e class etc etc....padahal b40 unemployed really topkek

Anyway, if anyone wanna install solar panels for home or business, kindly dm me lol

UBBL provides baseline. Meaning it tells you for certain space, it must have minimum opening for lighting and ventilation. This prevents idiots from designing low-cost housing with absolutely no windows to 'maximize profit'.

But, the minimum opening size defined by UBBL is not the optimum size. Refer below:



10% of floor size? That's really small. A typical 3x4m room is 12msq. Meaning the minimum size of the window is 1.2msq, which is about 1m x 1.2m. This is what most developers use as a standard. However, we now know (through science) that ventilation needs inlet and outlet. Providing just opening on one side of the wall does not guarantee air circulation.

And having a 2msq window pun tak guna if it opens to an airshaft that barely gets any light (like in some apartment/flat designs).

TBH old design use those swing open horizontally windows but not practical in strong wind/heavy rain scenario as the window pane friction is insufficient to brake

Then I went SG
already using sideways sliding windows since decades ago.

No need study THAT hard to know black traps heat more than lighter colours

Ya. Floor to ceiling glass windows are dumb in
Malaysia. Literally a living in a greenhouse
