Not just the temp, also the humidity, that's what's cooking us here in the Phils. Times really are scary now. In the early 90's or late 80's the highest temp we have in the summer was 39 degrees celcius. Now we're into the 50s.
39? sheet...it felt like hell for us. In 90' the highest temp during daytime is 22-24 degree celcius. Now its unbearable.
idk why it's not normal yet to own and use dehumidifier in ASEAN.
@@WildPrimateIt's because Air Conditioner is booming in 2000s. It basically moving the hot air in the building to the outside of the building, it didn't vanish out of it.
The theory is in 90's the outdoor and indoor is the same in 30 centigrade, but in 20's the indoor become average in 20 centigrade thanks to AC and the outdoor is becoming 40 centigrade, if you calculate the average of the indoor and outdoor it remains 30 centigrade, the AC is just moving the 10 centigrade outdoor.
@@Enseaclopedia So the AC is the main cause. We should bann all the AC.
@@Enseaclopedia can your humidifier cool down the temp outside? Can your humidifier cool down the temp for our farms so our veggies and plants are not drying up outside? Can your humidifier stop these forests fires that we never had before? Can your humidifier stop the Pacific Ocean from heating up so much that the 20 average typhoons we have yearly dont turn to SUPER TYPHOONS that from the usual highest Signal no. 3 for our storm signals now it's up to SIGNAL NO. 5? Yeah, right. Your nonchalant suggestion of using a humidifier wont solve this problem. This problem is bigger than your simple mind. 🙄
I'm glad Indonesia is using cool roofs to cool down the buildings. We have started using white colored roofs in my projects in Myanmar to reduce heat-gain from the roof.
Similar to Bermuda house roofs
better use thin reflective aluminium it last longer, white colour can lose it brightness quick due to weathering
Indonesians should take more inspiration from their traditional vernacular Indonesian architecture design. Build ventilated roof space for hot air to rise and expel the hot air. Also build on stilts to allow the air to pass under it, cross ventilating it and effectively cooling and combating humidity. None of these traditional vernaculars require white BeCool paint on their roofs. In addition, houses inspired by traditional vernacular architecture can also incorporate natural wood and bamboo materials which compared to concrete absorb less heat. Even Singapore architecture students can learn alot from these regional traditional vernacular building designs. Don't simply dismiss these lessons long learnt by past generations of their interactions with nature.
Things is..hot roofs only last one typhoon
Agree, also the existence of lawns surrounding the house is important, allowing the air to circulate around the house even better, adding tall trees covering the house from the heat rays. however, the using of wood for houses is quite difficult nowadays considering the amount of good quality wood for buildings might not be able to adjust to the high demand in the market. it also may cause a lot of deforestation. and our people tend to seek buildings with high durability (especially against termites) and look good not worn out, that's why they choose concrete over wood. they forget that concrete houses are easier to get damaged by earthquakes and wood materials can look good depending on how builders process them.
@@Nuiiya-h8l The fast growing bamboo is an alternative that can look into. Indonesia can try to research and develop industry standards to certify these as viable building materials.
like the house of the Banjar tribe in Kalimantan
The thing is... If they're made of wood,
Termites.
My family used to live in those spike-roofed houses, but had to move because termites were destroying the supports.
And also, the walls were not made of concrete. As it was a traditional house. Instead it was built out of wood, like in america.
I live in Phoenix AZ a desert area. Summer temps in the 40-46C (105-115F) range. The attic space is regularly about 65C (150F). But if a shade roof is built so there's a large air gap the entire house can always be in shade and the attic space will remain less than the daily high temps. So attic drops from 65C (150F) to 38C (100F) maximums and cools more at night.
Reflective is nice, but if you want to get serious better to reflect radiant heat on the house roof under the shade roof..
What on earth is shade roof?
@@adon8672 maybe plant some trees around the roof
Infonesia have high pitch roof in Minangkabau housrs
Putting a roof on top of your roof, roofception
Great idea, like double layer roof with open air in between
But animals like to live there too
Back then 20/30 yrs ago.. My grandfather make roof using nipah leaves.. Very coolingggg even in hot days.
totally agree. i heard before too.
True. My grandma's old house is also using these leaves as roof. Very cool. Unfortunately no body sells it anymore nowadays, at least here in my area
This needs good installation and better maintenance. You'll have to replace every single layer every 3 years or if needed.
We’ve used nipa leaves as roof in our beachfront villa here in Cebu, Philippines. It’s true, it’s cool in hot days. Our nipa leaves roof even survived with no damage during Super-typhoon Rai in 2021, 1 of the strongest typhoons that hit the Philippines in its history. Our neighbors lost all their tin roofs during the super-typhoon. The villa was the only 1 left with a complete roof in the area at that time. We specifically ordered the panels to be done traditionally so leaves are multi-layered then installed on the roof frames in a tight manner so more panels are needed to cover & then the entire roof was wrapped with a fisherman’s net to secure it. The roof installers even suggested to make the roof pitch steeper to make sure heavy rains drain fast & as they said for a longer lifespan so we followed their advise as they are the experts. The steep roof also makes for an epic ceiling height. It’s just sad that nipa roof suppliers/traditional installers are hard to find nowadays as it’s a dying trade (mostly old people). New construction mostly avoid it ‘coz it takes time & it’s labor-intensive when done right causing the cost to go up. If your curious how it looks, click on this: www.airbnb.com/h/thevergecebu
We still using this at some part of our home area. The only problem with this is maintained it for long periods especially the nipah palm leaves simply can't be randomly choose. It's hard to find the right leave even in big sq area of the nipah palm-tree. Believe it or not, this leaves can long last in prior 8 to 9 years might year more if it chosen & construct well.
This sounds like a great idea. However I am curious about paint. I would like to know the toxicity of it to the environment. And I would also like to know how long does the paint last before it starts peeling.
It is painted in roof, so it will not add no additional damage to environment
@Murugan Over time the paint will flake off due to use and age. The concern is the chemicals that are used to make the paint. Are they more toxic than normal paint?
I just painted our roof with regular enamel white paint from it's original red paint, reduced the temperature by 7 to 8 degrees c.
@@happygolucky143 oh wow 😮what an improvement
@@colasevenseas5652 the color white is the main reason, there are so called "thermal paints" but i don't know if the "pigments" they mix in the paint has an effect on the performance of the paint, i just came up with the idea of painting our roof white from red when i remembered the reason why space suits are color white
Having good airflow indoors is more important, but of course heat transfer reduction does certainly help.
the air outside is also hot lol. try hong kong
I’m really happy that Indonesian now are very fluent in English and the accent is really nice😊😊😊
Very true I like that ❤
Yes we are proud that more and more Indonesian citizens are able to speak in english fluently. That is because of our national educations curriculum issued by government. And more parents now have same understanding its very important for their children can speak in english.
😂 there is only a small minority who speaks English in Indonesia
Plant more trees is best solution compare to that technology based on local implementation. Temperature here in Jakarta could up to 33 degree. In Bandung, place the technology tested, the temperature is not that high already.
Trees take years to grow as high as the roof of the house.
sure. in the long run, but we need more short term solution as well.
@@laverne13well better start now , Jakarta Bandung green space doesn’t even grow yoy , think future ahead not just instant solution , plus so many god Daymn benefit from tree , it’s a no brainer , microclimate macro climate solution , fauna diversity , etc , of course I’m not saying , low tech it’s not needed . It’s should be a supplementary.
so how many trees you plant this week?
Ok, y'know, do both.
I just painted our roof with regular enamel white paint (glossy) which significantly reduced the temperature by 7 to 8 degrees in our case. I got the idea by observing the color of the astronaut suit which happens to be white. Also, try pointing a flash light at a white object, the light bounces significantly. Although I'm not sure of the exact content on some so called "thermal paints".
I am from India I tried many paints but it's effect is only for 2 years not tried enamel paint.
@@sundararajann6007 Paint should be glossy as much sa possible since dirt affects the reflectivity of the white paint. I'm from the Philippines and it's freakin hot now here since there is El Niño now. Remember to maintain the cleanliness of the roof so the paint maintains it's effectiveness, if it's dirty, the reflectiveness is reduced. Primer should also be white then topcoat is gloss white.
@@happygolucky143 I’m also in the Philippines. Our new home was built 3 years ago where we had 0.6mm metal roofing installed. The mild steel has formed rust in some small areas so I want to paint those areas before damage occurs. I’ll use epoxy primer then follow with high-gloss enamel. I should also mention the roofing screws are all rusted, thousands or them. I’m really disappointed with the quality of materials available in a known rust-prone tropical area. Where’s the aluminum I commonly see in Canada and US?!
its a mixture of particles that refract back primarily infrared. night hawk in light and other channels did some experiments and measurements.
Won't the heavy rains just peel off the enamel paint?
Taller ceilings heights with vents near the top. Allows hot air to move out of the vents. And planting more greens around the houses. Also using dark curtains to block out the direct sunlight.
One can look at the traditional houses near coastal villages. It was always cooler inside the houses no matter how hot or humid outside.
Edit: does soil on roofs help? Bio roofs.
No bio roof doesn't help at all. At worst you gonna get leak in Rainy Season. Soil in the roof maybe does help for winter season in Northern Hemisphere (maybe)
@@BigBlackCat im thinking of using
-plastic roofing modified to hold some water while keeping it from concrete
-peble to filter soil so it wouldn't get carried by overflow from rain
-soil
-grass.
As thin as possible so it wouldn't be so heavy.
use light colored curtains, but thick, not dark curtains ( :
@@justaguy-69 dark colored works better. I have both dark and light, the darker ones work better.
Putting grass mats over the roof could prevent the roof from heating.
I once recorded 38.5 Celsius in the city. But it recorded 5 Celsius lower when i returned to my suburbs with treesand vegetation. Cheers.
The house ventilation design must include air circulation openings as was the case during the 1950s. There was these air inlet and outlet on the walls and the roofs had special air ventilating tiles or air ventilator circulating unit. White lime wash for external wall painting does help with cooling.
This paint can be applied to outdoor walls as well. Remember, if the sun hits the walls it makes a big impact inside the house especially if its direct sunlight in the afternoon. Try touching your walls around 4pm and you will see what I mean.
Or build cavity walls
what will happen
painted my ext walls with hi gloss acrylic enamel and roof with gloss white oil enamel, cool 12 yeARS SO FAR NO ISSUES..
Yes, painting the outside wall white helps. I know from experience
This is something we can do as individuals that has a real and valuable effect. Automobile roofs too!
People who said need to plant trees, it isn't that simple. When it comes to climate change, it takes a lot to do and a lot to consider. In fact, South East Asia has a bunch of big forests such as in Borneo Island. Meanwhile me in Malaysia, I need to open the window at night during sleeping time to lower the humidity in my room. The least I can do but can't still sleep comfortably nowadays 😂.
it is difficult to plant trees considering that 90% of housing in Indonesia are close to each other and there is no land to plant trees either beside or behind like white people housing. It happen almost in all of asia even with developed country like japan and south korea the houses are very close too.
These are the people who detached from reality. Especially demographics, culture, and economic situation
Cing chong cing chong
Lol when we say plant trees it means we plant trees to reduce the cabon dioxide around the world not just ur house.
mosquitoes must be your regular 😂
Hi 👋🏼
I'm from Bandung, Indonesia
..but the humidity. Here in SEA, it really is not as hot in the middle of the desert but the massive humidity everywhere especially when it is hot then rains partially. More than ten years ago, I've already painted our roof white only to learn that the air gap between the roof and ceiling is where most of heat insulation is coming from.
Indonesia heritage build ancestor
1 Build steeped-pitched roofs
2 Use black soil base roof tiles (genting)
3 Use bare soil or stone floor tiles
4 Use black soil brick is cool
5 plant big tree around house like
6 watering a yard when heat too much
low cost but yet so effective
@@gusto2143 that's not low cost bro
roof tiles is way more expensive than that thin metals roof
@@elegancvn70 that depends, there's still a low cost option such as the traditional red clay genteng instead of the glossy ceramic looking one. Thin metal roofing such as Seng is definitely not recommended nowadays, Asbestos included due to the health hazard but people still use it a lot.
@@thecountremo
red clay is also more expensive
do u know asbestos roof?
search it than u will now the different, lol
black absorbs heat white reflects it..
I am in Rural South Australia, so naturally inside temperature can be high in summer. When planting a backyard lawn I decided to bury PVC storm water piping under it in a long connected pipe just 60 cm under ground. This pipe has a covered outside end and is connected into my house through filters into ceiling air vents. A single variable speed fan is used to draw outside air through the pipe where the ground temperature can lower it to close to 15C. This is an extremely cheap and effective household air conditioning system and over ten years have only had to change filters annually.
Cool
Hey why don't you make a video about the system in place?
You could inspire a lot of people to do the same
So basically a system similar to the qanat system? But wouldn't that be more humid?
Sounds like a simple heat pump system, using the ground as a sink to absorb heat from pumped air. Do you have problems with water condensing inside those ground pipes?
Imagine that, people in bandung talk about how hot the weather is, mean while jakarta people go to bandung every weekend just to cool off
The problem is that there's little low tech solutions for reducing humidity. I'm assuming Indonesia isn't as humid as here in the Philippines. It's the humidity that makes the heat insufferable. You can prevent the house from heating up all you want bit if it's humid, it's still going to feel hot.
This week we've been getting occasional thunderstorms in the afternoon but even that is not enough to cool the place.
Jakarta humidity is about 90% normally
In my place Palembang, the humidity is above 90%
you only need to use cross ventilation and bigger ventilation. if it's not possible, you can use exhaust fan to have the same effect as cross ventilation. the humidity is more bearable when you have good airflow.
@@alvintsai1161 it is still sticky though. Sometimes even after a thunderstorm has already cooled down the temp, the humidity remains. Once you sweat, it'll just remain sticky and feel hot even when the air is already cool and you have all the fans on. I hate it! 😣
Indonesia right now recorded by BMKG (Indonesia meteorology and climate control) humidity about 99% this year, this is the highest number compare to 2020 recorded about 85%, that is why Bandung used to be cool place become hotter this year
It basically paint your house or roof or wall to clear white .... because White will reject the Heat, any color directed to dark will generate heat. And for the roof you can use double or triple layer roof with hollow on the middle to disperse the heat and hot air from first layer and so on .... or paint your wall with anything wall paint with alkyd synthetic, because alkyd synthetic paint will repel the heat.
It’s not only the roof, but also for wall. And it will reduce heat that was stored in the concrete. Thus a much cooler room temperature.
Use clay roofing or concrete roofing as it helps reduce heat but if that's too expensive the solution is to disipate heat below the roofing chamber by applying ventilations. It can be modifying the roof or making some holes on roof wall The more hot air circulated via exhaust holes the more heat will be reduced.
Clay & concrete absorb more heat making you feel like you're a bread baked inside the oven even at night. Ventilation can't help for reducing the heat unless you make some other cover on roof to prevent direct heat.
@@royelcharles2554 It's based on my experience i have three houses. One used concrete roofing with multiple hole outlets,one with clay roofing belongs to my mother house with a few hot air outlets, one asbestos roofing with a few hot air outlets. Among thoses materials based on my personal experience the clay and concrete shows different temperature. Those houses dont have air cond. Sometimes i check those roofing to find out leak or rats nest. I find the heat is not so intense compares to asbestos roofing.
Install solar panels. Cover your roof and power your house at the same time 😉
Painting on metallic roof can cause unexpected issue. Paint will form hairline cracks from expansion and contraction. The cracks will then cause the surrounding paint to form a bubble like shape and may continously expand under the right condition. The air inside these bubbles may trap higher pressure humid air during the day. Some screws may end up being severly corroded within a short period of time. I think this problem can be simply avoided by not painting over any screws on the roofing.
High tech paint already have elasticity formed after the paint set. That create some flexibility to handle it. However, i dont know if thats the case in this product.
@@RapidReveal541 It would be the case if the high-tech paint you're speaking of costs 100 bucks for the number of pails mentioned in the video.
You probably never know about waterproof paint
waterproofing does not reflect sunlight, sadly.
Galvanization was invented Decades ago, why don’t we see this in the roofing materials and fasteners where we need them most? The answer is profit. Business can’t make as much money from you if you don’t need their product as often. It’s pathetic and I’m tired of seeing this especially in Southeast Asia.
Usually to make it effective you need to install aluminium foil on the roof. Plus exhaust fan. The humidity plus heat really radiates heat at the home all day
In addition air insulation padding, and AAC concrete blocks can be good insulators. If availability of water is not an issue, water sprays can help (like sweat).
Cool technology.
Building house with air circulation in mind is the best.
My house is typical housing complex build, but mine has less problem on room temperature because it have open roof in the back.
So wind in my house can go freely from front page to back or the otherwise.
We also using less lighting on daytime
Ujicoba di bandung? Bandung mah sejuk. Uji coba di jakarta deh
Jakarta kuatir gagal !
😂😂😂
@ 4:18 were the effects of cold temperatures lessened? If so, how does less cold compare to more warmth?
I’m on the first floor, not direct from the roof and it’s already freaking hot. Finally decided to get an AC because it’s oven hot during midnights. Crazy times and summer just keeps getting hotter every year.
hope this could be implemented widely in many places in indonesia... not only be a good research output only and then disappear.
Good job, CoolRoof!
they should test the coating in Bekasi area, not in Bandung... Bandung is quite cold not as hot as they say.. put the coating in a house in Bekasi, then we can tell whether the coating is working or not. . .
In the Philippines we use #nanocoolreflectivecoating a top coat for metal roofing and also for concrete roof deck and walls.
Traditional kampung houses in Malaysia are built ergonomically & are beautiful to boot.
Bandung is the most Cooler temperature than any Indonesia city
in bandung upper side, if you got shade, the wind is very nice, you don't need air conditioner.
It's always good to have more options to cool down our living spaces, especially in the tropics.
Curious about something: Why not coat the exterior walls too? It's low-cost, so it shouldn't be that hard to break even on energy savings, no?
There is not that much horizontal lights to be (un-)absorbed anyway.
This product works by reflecting lights that would normally be absorbed by normal roofs
Most houses in Indonesia are build using thick bricks. It's very good at termal insulating
@@thanosal-titan not anymore, the white bricks gets hot, it's really bad when the wall get hit by direct sunlight
i painted my walls white acrylic latex and roof white hi gloss enamel
It definetely makes a big difference if you paint the outside walls white. Many houses in Indonesia are built with materials that attract heat. Most houses are built poorly unfortunately. However, if you paint the outside walls it certainly makes a difference. I speak from experience
I hope this becomes available in Lazada.
Very essential when building residence.
Great idea however im curious to know why they cant just measure the indoor ambient temperature before and after the paint? why measure the surface temperature?
Because, the office or home of the participants is never fully sealed... The door always open to let the air circulate, and i dont think that people in the rural area know what ambient temp is (not that they're stupid or uninform). Its just that Indonesian tend to generalize things.
They should compare the temp at the roof before n after
there should be a standardized, organization-approved way to measure cooling index. Every brand says they can cool but there is no number to compare, unlike air-conditioner.
We Singapore can also adopt this practice
Like a crazy person and becoming the talk of the colony, I switch off all lights and open every door window motor vent at around 9pm for half and hour
What happens if you deflect the heat instead of absorbing it? Will it increase the atmosphere's temperature more like a mirror reflecting more light?
in India they use a stock of pot with water fall. it may be usefull here in the PH 🇵🇭
i agree it does help. moved the water filter from the pond outside to a makeshit waterfall installation indoors. moved more plants indoors. bought mist fan... every little bit helps
Salamat Philipina, Ang Ulap Sa Langit
should hv this in sg too & reduce use of air conditioning
the point is just paint your roof with white paint (whatever the brand) it's also the reason why most of mosques in the world are painted in white and the cloth of ihram for Hajj in Mecca must be in white, it is to make the worship feel more comfortable
The most efficient, effective and low cost is to plant more tree around the house
My dear friends all the reflective material is good.
On the other hand please collect the water condensed from the A/C and use it.
Lots and lots of pure water is going into the drains.
I collected from a 1.5 Hp. Unit 18 litres of clean water 10 to 12 hours operation.
Can you imagine high rise building's having tons off A/C units running for hour's.
It was done in the philippines since 2013 its called NANO COATING.. try to looked at in youtube
I live in east borneo and the heat is super.. it's hot and humid. I don't go outside after 10am - 4pm.. using fan almost 20hours a day. never experience this kind of weather ever in my life
Siap2 aja el Nino mau datang beberapa bulan kedepan. Makin panas gaada hujan, belum lagi ada yang bakar2an
terasa lbh panas karena angin kurang bu
jadi harus dibuat ada pergerakan udara-angin adalah udara yg bergerak yg berarti ada perbedaan suhu panas dan dingin
jika ada kolam itu bisa dipakai
dan tentu saja pohon
satu lagi
apakah arah kipas sdh tepat bu?
saya sdh pake metode arah kipas ke pintu atau jendela dan lumayan adem
dengan arah kipas yg tepat udara panas yg terperangkap di dlm rumah akan keluar
selamat bereksperimen ya
i love my white car... is all about reduce heat
Well, why not our Malaysian and Bruneian homes as well.....not just Indonesian homes, when it comes to the usage of the BeCool cooling and coating solution.....
Economic of scale. The most populated areas in Malaysia are town areas. Not many single houses. Most are apartments.
We need this in the Philippines.
Indonesia is tropical country. In Indonesia everyday is summer, so every single day you need to turn on your air conditioning. This is the different with subtropical countries that have 4 seasons.
Why don't we have this in Malaysia!!!!! Yoooo! I need that~
Try search king kote
I think a big pokok and good insulation is better to handle this Metal roof. Because metal roof does not have much UHI, just that the house hot.
I think any roofpaint that is white..is good for sunlight reflection. I am using ordinary white roofpaint. It really decreased high temperature inside the house.
At least there are such technology these days
Out of topic but these people have such good skin!! In such heat!! How??!!
My clammy summer skin needs to know!
I think it's the humidity. Tropical climate.
This is good...I was thinking this last 20 years ago...why Asian countries so late to think this problem...hot weather countries should have roof technology last 100 ago before...
I'm wondering if a community paints all the roof white, does that help to cool down the area more than if a single building's roof was painted?
We have here in the philippine like "be cool" it was a garlerking thermal paint. But the paint has only for 1 year used. I think in my opinion white glossy paint is enough to repel the heat.
Bandung is cooler area with or without painting roof. I live in bandung for 5years befor move to bali. If you wanted make challenge go to north beach area like karawang or Indramayu that have high humidity and super hot temperature
I think dessert water cooler will do great in there.
it's just white paint double-coated. white tiles are thicker and much denser and last longer
The first person said it cools from 32 C to 27 C, that's significant (which I doubt). Later person said only 1 degree C (more believable).
Most Indonesian houses has an air pocket as a buffer zone, called plafon.
Climate change is the term often used by westeners. What we experienced now is also what i experienced as a kid in the 70's. Generations today are so used to airconditioning and heaters.
We prepare for the worst in august this year, El nino is coming. Anyone notice its getting hot for the last 2 month ? same in indonesia, even in the night i used two fan and one aircon. i lived alone, and hell yeah the bill increase. Maybe i need to change my roof next month, not bad a white color roof for a while.
There are no tall trees (no shade) near the house while the front is all paved. No wonder it's getting hot in- and outside.
No need for toxic paint.
The man at the end is probably the salesman and definitely sits in an air-conditioned room.
it just matter of colour of your roof, dark colour absorb more heat than bright (white),, you can campare to touch white car and black car in midday,,, dont forget air circulation 😇
- Living Roof 🙂
Try! It has a lot of benifits, and one of the side effect is just your home will Reduce a lot of heat for Free!😁
I would like to see you try that solution in Jakarta... Bandung should easily achieved that due to their MSL values...
The solution is very simple. PLANT MORE TREES. CUT DOWN LESS TREES.
i painted my roof hi gloss white enamel in the philippines, seemed like common sense, it has lasted 12 years so far and my roof is cool to the touch, before i could EASILY cook an egg on it. prime with iron oxide first.
The way they build houses in Indonesia is like building ovens in the sun. They use AC as the standard solution but only simple white paint like this one or white paint in general makes a big difference. I really don’t understand why the Indonesians not built their houses cooler using different materials, paint, and everything required for natural cooler environment. The architects there need to scratch their heads before they start a new project.
There is no magic as some might believe regarding these coatings. They may help to be a part of a solution if they are easily available and reasonably priced. How long last they, how about measuring the efficacy after one year etc ?The greatest help to cooling homes is knowledge.
I am curious as to the toxicity level of this product. Many homes in the countryside use their roofs for rainwater collecting.
The key is "low cost".
Great! project 👏👏👏 , I hope the The Global Commission on the Economy and Climate support this as the world 🌎will benefit from it
Is this available in the Philippines?
😍
Nice roof paint. Is this available in Malaysia? Interior Designer here.
Wow Amazing
Will reflective paint make the surrounding temp rises?
Yes.
Good question
no but it will be a lot brighter!
@@naisue so if the whole village paints their roof .... imagine how hot outside will be.....
White paint does it have the same reflecting light like glass house effect?
what i can't understand here in thailand, especially in bangkok there are more and more skyscrapers in dark colors, mostly dark gray almost black....they heat up in the strong sunlight...our neighbor had his whole roof tiles painted white That wasn't cheap...but after 2 monsoon seasons you can hardly see anything of the white color...his investment was for naught
Did the paint chipped off or was it covered by gunk? Maybe he can try pressure spray it to see if there is still paint underneath?
I think your neighbour didn't prep the roof properly before painting. There are outdoor paint made specifically to withstand outdoor elements up to 5 years
in Australia is very popular and fashionable the black roof...but downunder's are more intelligent.
most of our buildings in south east asia are paint in white already BUT....the temperature is still unbearable inside a concrete house and buildings, panting something white is nothing new, Bandung and Tangerang actually have a temperate climates compared to other city or island in Indonesia, try doing it in Sumatra or Kalimantan which sit right on the equator lines just like Malaysia and Singapore, this is where most people are complaining about heat wave...it wont made much different in temperature here near the equator compared to Java Islands which is way further south from the equator. That is why most of the traditional houses in Sumatra, Malay peninsula and Borneo/Kalimantan area are on stilts and have a lot of ventilation and high ventilated roofing unlike in Java.
Why we need AC when we have more natural ways? The only thing we need for more natural solution was AG (Angin Glebuk)
reflective roof..it might cool the room temperature in a building but what about oustide the building? doesnt it makes the enviroment temperature rising? plus it maybe potentialy hurts our eye?
no, it wont rise the outdoor temperature, it'll even help to cool it down because its also lower the urban heat island effect. most of the reflected heat is sends back to space, assuming there isn't much cloud in the sky. and about how it might hurt the eyes, well its not like you're taller than the roof that's becomes your proble
still much better than AC which directly spew hot air to the outside
@@newthian1783 yeah, and there are now a similar technology that uses the same principal as this but they use it to radiate the heat generated from air conditioner into infrared which then can be radiated to space
@@doodleydude7833 But doesn't it would makes the air on the space become hotter? Heat radiation? I dunno dude I'm ignorant on this matter.
Yes we're not taller than roof..but I'm talking about those who see it from outside the house from some distance.
There is a newly built house in front of my place..it right side wall faced towards west (my place faced towards east) and they painted it bright white.. I assumed to reduce heat on the wall.. when the clock passed 12 on the sunny bright day..I have to squint my eyes when I go outside..and I feel my place become hotter since that house been built..but this could be just my feeling.. didn't measure the temperature before and after. I dunno.. have you try this roof for yourself? Btw I live in Indonesia.
@@dedybadharu2804 i assume what you mean by "space" i the earth atmosphere and if thats the case then no, it wont make the air hotter. you see, a darker colored surface absorb the heat from the sun making itself and the surrounding area hotter, that's why the area near an asphalt road feels hotter than a concrete road, its called "urban heat island effect" you can look it up yourself. and contrary to the darker surface a lighter surface reflect back the sunlight in all the wavelength of light but mostly infrared back into space or outside the earth atmosphere.
about the shiny wall paint tho that's sounds awful, maybe try to use a semi reflective film on your window or if it's makes your house hotter maybe try use a low shgc "solar heat gain coefficient" window, though it'll be expensive.
and also, aku wong jawa lur hehe
south jakarta, indonesia. we're having temperature rise here. the solution is quite simple and zero cost energy really, short pants and ultra light shirts. aircons and fans are for crybabies
LOL
even cheaper if they just use muds. go get some dirt/earth from the ground, mix with water, make them lumpy, then just apply them. the only problem is they need to be changed every week, they stinks and ofcourse make ur roof dirty. but they do indeed works wonder.
Ppl who told to plant more trees look at your country 😂
Indonesia is more green than your country, even the capital city 😂
Ohhhhh just like tech ingredients.
Even by doing white color on roof top and walls temperature can easily be controlled
As a Indonesian! I'm really proud of Vladimir Putin
Go Poetin!
Go Brandon!
Can we use white paint? Or it must specific paint?
Yes, it is the high humidity levels, that are unbearable because high humidity deprives the body of its ability to cool itself by normal perspiration. Therefore, it is better to use solar panels and wind turbines coupled directly to DC driven air-conditioning compressors, that can be effectively used to keep humidity under control. Backup energy, stored in batteries could be used after sundown, to keep up with de-humidification till the next morning. These air-conditioning units must not be used for aggressive cooling, because energy requirements for cooling is much more than just humidity control of a confined space. From a comfort point of view, humidity control is the only solution in such costal areas.
I live in a hot, humid area. I run dehumidifiers at night when it's cooler, and it's enough that the house is comfortable during the day.
