Cooling Your Philippines Home - Artificial Shade and Polystyrene Insulation

Cooling Your Philippines Property – Artificial Shade and Polystyrene Insulation

Being amazing in the Philippines can be a bit of a obstacle.  To start with off, it is the tropics, and except if you have essentially seasoned that degree of warmth and humidity listed here, changing to it can be a little bit of an ordeal.  Secondly, the way they construct houses (and flats) in the Philippines truly will make the warmth even additional intolerable.

It’s April 8, 2016 and summer season in the Philippines is in total result.  It’s been over 90 levels Fahrenheit (32 Celsius for those people in a lot more enlightened, metric-helpful nations) this earlier week and the humidity-inclusive “Real Feel” temperatures have been hitting 110+. 


The aircon went on this morning at 10 AM, and it will in all probability be running until about 5 PM.  It will go back on 3 hours afterwards when I settle down for the night and it will be jogging off and on during the night. (Our Carrier Optima aircons have a timer that switches off the aircon and turns on a fan following a set amount of hrs – then, when it will get much too warm, I wake up and switch it on for a few much more hrs.)

To combat the Philippines summertime warmth, we’ve produced a couple of advancements to “Pink House” since we moved in.  I’ve only in fact received two shots to clearly show when it arrives to some of the property layout “before and after’s,” so let us acquire a search.

Notice:  All temperature readings are manufactured with our trusty temperature gun.  These handy small units accurately study temps from up to 10 meters away and only price about 11 pounds US on ebay.

Pink property shortly following moving in – no shade!

Very first up is the photo earlier mentioned that we took shortly right after we moved in to our rental situated on the outskirts of Dumaguete Metropolis. 

Take note a handful of factors: 

CONCRETE AND Steel: 1st off, the property is manufactured of (uninsulated) concrete block walls capped by an (unvented) metallic roof.  There are eave (soffit) vents installed below the roof overhang, but there is no ridge venting.  The goal of eave/soffit vents is to attract in cooler air from down below and vent out the hot air with ridge venting.  But with no ridge venting, there is nowhere for the sizzling air to go, so the cavity in between the roof and the suspended ceiling (attic/crawl space) turns into tremendous-heated through the working day and radiates it down into the household a lot like a convection oven.  End result is that the ambient temperature exterior will be 90 levels although the ceiling temperature inside the property will be near to 98 levels. 

Sunlight Publicity: To start with off, there is Incredibly minor shade around the home.  When Filipinos build, the first factor they do is slash down all of the trees and brush.  So, when the uninsulated concrete “hollow block” and unvented steel-roofed framework is finish, it speedily turns into a aforementioned convection oven.

Now, let us get a glimpse at the property following we produced some variations to cut down on the heat.

NIPA CARPORT Go over:  This was the to start with improvement we created.  The sunlight beating down on the concrete driveway and walls on the western aspect of the dwelling would provide all those surface temperatures up to all-around 130 levels.  The warmth would then waft into the house, elevating interior temps to 90-92 degrees.  I very first made some do-it-yourself “sunscreens” to protect the western home windows, and these assisted considerably but wherever a suffering in the ass to constantly set up and consider down each and every day (alongside with acquiring to open all those people windows in the evening and near them in the morn).  Eventually, we questioned our landlord if we could shell out to have a carport address made and have the charge deducted from our rent.  He agreed and the nipa (native content) carport was put the following 7 days by some community personnel.  The results have been Immediate – the shaded concrete thereafter would only heat up to ambient temperatures and the shade was far more than welcome.  Note that they didn’t angle the nipa steeply plenty of so it’s not absolutely waterproof but which is Alright – I was additional involved with shading the overall facet of the property.

INSULATION:  While we experienced diminished the house’s ambient temperature by making the nipa carport include, we still had a great deal of warmth radiating down from the ceiling.  I had produced the window “sunscreens” out of the 10 mm polystyrene insulation here that has a reflective radiant barrier (essentially, aluminum foil) on just one aspect.  Imagining that it may possibly aid, I when yet again asked our landlord if we could set up the insulation atop the suspended ceiling.  Some folks on one of the Philippines expat boards observed that while slender, the insulation was rather helpful.  They also went on to take note that they believed most of the result was owing to the radiant barrier/aluminum foil reflecting the infrared radiant heat coming down from the metal roof.  Again, we paid for the set up and the landlord agreed to deduct if from the rent.  We 1st did the two bedrooms as a exam, and the success were being fairly sizeable – the insulated ceilings were being consistently 3-5 degrees cooler than the uninsulated ceilings.  About a week just after the bedrooms ended up finished, we experienced the relaxation of the dwelling completed.  Our lousy Filipino employee busted his ass up in the tremendous-heated crawlspace, laying down the insulation, stapling it in put and taping up the seams.  The materials value for the two 3 meter by 3 meter bedrooms was about 1,560 pesos (78 pesos for every sq. meter for the 10 mm poly with one-sided radiant barrier) and the later on price tag of the rest of the property was 3,800 pesos.  Toss in labor and the full insulation job price 6,200 pesos.  So, for about $135 USD, we now had an insulated ceiling.

Once more and like the nipa carport go over, the results of the insulation had been quite a great deal quick.  Ambient temperatures in the residence decreased about 3 levels from just before the set up, and even nevertheless 3 degrees may possibly not seem to be like a lot, I would much instead be sitting in a house that is 86 levels as opposed to just about 90.  I also think that the insulation will aid with the aircon expenses.

Combining the shaded carport on the western side of the dwelling, blocking off one of the windows in just about every room with poly and insulating the ceiling have certainly created the house additional comfortable, temperature clever.  Aside from central aircon, there isn’t significantly you can do about the humidity, but I glimpse at it like this – at minimum I do not have to have pores and skin moisturizer although dwelling in the Philippines!
