Passive Ventilation of Modern and Traditional Malay Houses

Passive public discussion of unexampled and conventional Malay digestsComparing the Passive Ventilation Style of youthful Malay House in Belum rain forest compensate With the Common Traditional Malay House in Malaysia.ABSTRACTThe objectives of the search is to examine the unresisting stocking style of Modern MalayHouse in Belum Rainforest Resort with the common Traditional Malay House in Malaysia. Theresearch questions atomic number 18 what are the comparison of supine respiration in Modern Malay Housein Belum with the common Traditional Malay House. Secondly. how does the preference of grammatical construction affect the passive respiration. Finally. How does the the passive ventilating system systemworks for Modern Malay House in Belum Rainforest Resort and Common Traditional MalayHouse in Malaysia. These are the list of methodological analysis that being used to help my research. Siteobservation at Belum Rainforest Resort. internet research. articles and books. My analysis ofmethodology is by studying and comparing the details of these two rears that are related tothe passive ventilation. The result is i nominate that Modern Malay House in Belum is lack ofdetails that contribute to passive ventilation system. Common Traditional Malay stick out is stillthe best since it gives spotlight more on the passive ventilation. In a nutshell. reside that focusmore on the passive ventilation are much better since it shrivel the humidity and gives a safe(p) thermal comfort in a twist. In future. i hope that people entrust design buildings thatconcentrate more on the passive ventilation rather than design.1.0 INTRODUCTIONWhat is computer architecture ? The definition of Architecture is the art or practice of designing andconstructing buildings. Architects are the one who runs the orbit. They create an enjoymentstory in every building that they design so that the world would non be as boring as it is. When it draws to architecture world it is super wide and it represent of many different styles andtechniques. Every country adjudge their own styles of designing to utter their country suniqueness. One of the best design in the world is the building that meet the need and prettymuch response to the climate. Also. It needs to know about the microclimates and the climatezone. know the basic physiology of human thermal comfort. reduce the loads and enhancevisual comfort by controlling the sun. Thermal mass are used to improved the comfort efficiencyand to pick a space-conditioning strategies that are climatic responsive. Vernacular architectureis one of the architecture style that take seriously on all of this criteria when designing a building. Vernacular Architecture is being refer as a conventional buildings that are designed to meetthe local climate and culture. They design with using a deep mind together with arespect towards the nature. Vernacular architecture female genital organ be called as a sustainable archite ctureas well since it are likewise built to sustain the environment without destroying it. Vernaculararchitecture tends to evolve time after time to resile the technological. reflect the historicalcontext in which it exist. reflect the cultural and to a fault reflect the environment. This style ofarchitecture used the local resources and available energy and materials. so it evict refer matchly to the climate. site and culture. The al more or less common basic function in vernaculararchitecture is to shield and protect from the weather conditions.Passive sang-froiding system can non be separate from the vernacular architecture as they aregreatly related together. Passive cooling is a building design approach that targets on the take firegain control and heat dissipation in a building in order to improve the indoor thermal comfortwith lower or zero energy usage. A frank orientation of a building. proper design layout andsystem used in a building will digest the passive venti lation system be in the building. Ventilationis the main criteria in passive cooling system as it is the one that move the strip from outsidebuilding to the inside so that it can improve the thermal comfort of a building. And my casestudy is to compare the passive ventilation of Modern Malay House in Belum Rainforest Resort ,Perak with a common Traditional Malay House in Malaysia.2.0 An Overview of the Modern Malay House in Belum Rainforest Resort. Perak. MalaysiaAs stated on Malaysias online website. Malaysia is a country that being classified asa country that confound a torrid climate and humid tropical climate with all months above 18 degreeCelcius. Belum Rainforest Resort is the speckle which I picked for my case study. BelumRainforest Resort is located on the northern part of Malaysia and just below the boundary of the another(prenominal) country which is Thailand. Belum Rainforest Resort is located in the middle ofhobo camp which is surrounded by the water element from t he Lake of Banding or Tasik Banding.This make the place a great wrick as a great place for the passive cooling design.Extracted from http//lensahijau.blogspot.com/2012/10/the-establishment-of- air out- signboard-standard_18.htmlThe Malay House in Belum was design to be modern but yet still maintaining the basicelement of Traditional Malay House. The photo below is one of the Modern Malay House inBelum Rainforest Resort.Extracted from http//www.maplandia.com/Malaysia/perak/gerik/hotels/belum-rainforest-resort/The similarity of this modern Malayan stand with the traditional malay hold in Malaysia is theyused completely 100 per cent wood as the main material for construction.3.0 What are the Comparison of Passive Ventilation on the Modern Malay House in Belum Rainforest Resort with Common Traditional Malay House in Malaysia ?A traditional Malay House produce the ventilation by applying many of full lengthwindows and doors at the body level. ( Yuan, 1987 76 ). Hassan and Ramli ( 201 0 )conclude that Huge openings on Malay house walls produce high air intakes outside tolowering the performance of stack effect. The below draw stated clearly that. most of theoutdoor and indoor temperatures were higher than 28 degree Celcius with the humidity levelin the house is higher than 60 per cent and the wind speed in Malay house head for the hills in about 0.3m / s to 3.4 m / s.Extracted from http//lensahijau.blogspot.com/2012/10/the-establishment-of-air-house- standard_18.htmlThere are several comparison that can be found in Modern Malay House in BelumRainforest Resort. The Modern Malay House in Belum were design using a timberconstruction. Most of the timber construction are not solid if to compare to a concreteconstruction due to being build set by piece. Since it is build piece by piece so it willhave a small gaps between a piece and a piece of wood. This small gaps is one of thestrategy in passive cooling system. The function of the small gaps is to allow the moveme ntof air into the house so that it could ventilate and automatically improve the indoorenvironmental quality. Most of the traditional malay house have this thing but if to compareto the modern side of malay house in Belum Rainforest Resort. it does not have this thing. Itdoes not have small gaps on the wall and floor. the small gaps only can be seen on theoutside of the house which is on the balconys floor. This is not good since it blocks the airfrom entering into the house. The unique thing about the Malay house is that it is built onstilts. This approach in many ways has several benefits from a thermal, functional and safetypoint of view. The raised floor, which is built higher than the ground, can catch winds of ahigher velocity ( Yuan. 1987 71 ). and the use of timber planks for the floor, which havegaps between them, can bring the air into the inner space.The Balcony area that need small gaps for air ventilation purpose. The inner side of the building which does not contain any floor gaps and wall gaps. Other than that. during my site observation I found that at that place is no ventilation by dint ofroof marijuana cigarette that can be found in the house. This ventilation through roof joint also contributein Passive Cooling Design. It makes the house produce a large movement of air into thebuilding through the roof joint. Traditional Malay House really focus on the opening so thatthey can have a good thermal comfort without producing energy that we do not need such aselectricity. Also. without opening through the roof joint the stack ventilation system willobviously not happen.Extracted from http//lensahijau.blogspot.com/2012/10/the-establishment-of-air-house-standard_18.html How does the Passive Ventilation System Works for Modern Malay house in Malaysia and CommonTraditional Malay House in Malaysia ?Extracted from http//www.belumresort.com/acco_kampung_house.htmlThe floor plan above shows the floor plan of the Modern Malay House in Belum Rainfore stResort. Common Traditional Malay House Floor PlanExtracted from https//www.academia.edu/2377416/Chapter_2_Malaysian_Vernacular_Architecture_and_Its_Relationship_to_ClimateBoth Modern Malay House and Traditional Malay House are helter-skelter arranged. This isto ensure that the wind velocity in the houses in the latter path of the wind will notsubstantially being reduced. Stack ventilation is the flow of air from outside which enter into thebuilding and goes out from the upper side of a the building. Stack ventilation use differenttemperature to move the air. Hot air increases due to the lower pressure occur. It is sometimesbeing called as a buoyancy ventilation. The below diagram shows how the stack ventilationbasically works.Extracted from http//sustainabilityworkshop.autodesk.com/buildings/stack-ventilation-and-bernoullis-principleStack ventilation is one of the unique ventilation system that happen in a traditional malayhouse. Based on my observation on the modern malay house in Belum Rainforest Resort. Ifound that there is no stack ventilation happens on this house since there is no opening throughthe roof joint for the air to go out. The other problem is this house does lifted up a bit by thestilt but the other problem is that there is no floor gaps for the air to come in from below. Thismodern malay house in Belum Rainforest Resort does not have the stack ventilation effect compare to the original traditional malay house. The traditional malay house use the stackventilation effect to cool the inner side of the house. Stack ventilation makes the movement ofthe air flow and enter from the opening on the downside and the side of the house. Then the airslowly vary to the upper side of the house and goes out through the openings on the roofjoint.Extracted from http//malay101.blogspot.com/2012/08/malay-architecture.htmlEven the modern malay house in Belum Rainforest Resort does not use the stackventilation system. they use the other system of ventilation w hich is the cross ventilation system. Cross ventilation system is obtain when there is windows on the both sides of the room. Thiscaused the air to flow across the space. Since the wind comes the most on the side of thebuilding. Openings on the sideway really helps the modern malay house in Belum RainforestResort to give a better thermal comfort. The cross ventilation system is good since it reducingthe energy consumption in a building. The below diagram shows the cross ventilation systemthat happens on modern malay house in Belum Rainforest Resort.The arrows on the diagram above shows the air movement that flows into the house. Other than that ,the unplanned arrangement of the Traditional Malay House is really heavy as it gives contribution in reducing the riskiness of the strong winds. ( Hanafi. 1994 ). Settlements that are along the coastal areas experience great wind speed than the inlandreligions. ( Hanafi. 1994 ) Traditional Malay House are usually destitute and it dispersed theunits with ample external space. This is to allow the fresh air circulation occurs in the building. (Hanafi. 1994 ).Extracted from https//www.academia.edu/2377416/Chapter_2_Malaysian_Vernacular_Architecture_and_Its_Relationship_to_ClimateExtracted from https//www.google.com.my/maps/5.5428286,101.341145,187m/data=3m11e3Photo above is the rough arrangement of modern malay house in Belum RainforestResort. The arrangement are based on the linear concept and which it is applying the sameconcept as the traditional malay house in Malaysia. How does the orientation of thebuilding affect the passiveventilation?Building orientation are really important in malay traditional house. For religiousreasons. most traditional Malay houses are oriented to face Mecca(east west direction) ,which indirectly minimizes the area of exposed walls to direct solar radiation during theday(Yuan. 2011). The building orientation also does help in providing good sun shading. andalso a good ventilation system. Normally. the Malay Kampong House will be orientateaccording to the east west orientation. This orientation function as letting you to harnessthe daylight and take control of the glare along the long faade of the building. It will reducethe glare from the setting sun or even from the rising sun. One more reason on why east west orientation is the best orientation is because of it ensures the building to get a betterthermal comfort. The photo below show that the not so accurate wind diagram that beingtaken from the windfinder.com.Extracted from http//www.windfinder.com/windstatistics/butterworthBased on my research study I found that most of the wind comes from the Northwest andNortheast side. There is least air comes from the northern and the southern side. Thisorientation system works pretty well since the modern malay house in Belum Rainforest Resortare orientated using the east west orientation. The window on the modern malay house inBelum Rainforest Resort that located on the side of the house is openable so this can make thewind to flow into the building and circulate in good way. The below photo shows the orientationof the modern malay house in Belum Rainforest Resort.Extracted from https//www.google.com.my/maps/5.5428286,101.341145,187m/data=3m11e3Building that are surrounded by the water element are good for passive cooling design. What I found is Belum Rainforest Resort is surrounded by a big lake which is the Tasik Banding. This Tasik banding contribute pretty well in making the house cold and achieve the correctstandard of thermal comfort. The wind which flow from the Northwest side brings the cool airfrom the lake and directly enter the building. ConclusionIn a nutshell. Malaysia is a country that are meant to be as a hot climatecountry with a high humidity level. Houses in Malaysia that will be design or alreadybeen designed by people need to follow the Malaysia s climate to achieve a goodthermal comfort. Modern Malay House in Belum Rainforest Resort are lack of theoriginal features that suppose to have in every Traditional Malay House. tidy sum thatdesign the malay house in Belum are not concentrating on the features anymore. infact they are more in terms of creating a impudently building with using a different way toachieve the thermal comfort. The house might look like a malay traditional housewhen you look it from the farthest distance. but it is totally different when you comecloser and study about the details of the house. Modern Malay House in Belum arelack in terms of passive ventilation contribution. The house pretty much does notapply the basic elements of a traditional malay house which is to have the wall gapsand small gaps between the timber for the air to move into the building. This is sucha waste since this small features is actually really make the building to achieve a verygood environmental indoor quality. The ventilation through the roof joint also is agood thing when it comes to express the stack v entilation system. Since traditionalmalay house dont use the electricity more often than a normal building. this stackventilation really works in every traditional malay house because it reduce the energyconsumption and automatically reduce the living cost. Also. stack ventilationmakes the traditional malay house to get a maximum ventilation from almost everyside of the house which the wind are basically come from the bottom. middle andeven from the upper side of the house. Other than that. the layout arrangement inmalay house will contribute in making the place become more comfortable. Layoutarrangement is one of the criteria in vernacular architecture. this layout arrangementwill contribute on the flow of the wind. Last but not least it is important as well toorientate the building in a proper direction. The proper building orientation will makethe building to receive a good sun shading device. better air ventilation system sothat the building would not be hotter on the inside.
