When will build the house, everyone would expect if the house is built it will be called a house meeting and a beautiful, healthy and comfortable. For the beauty aspect of course is relative, because the view is usually not the same when it comes to the beauty of the building. But when it comes to the health aspect, usually the default is uniform. In this case, we would probably agree if it's a healthy home meet several criteria, including: good air circulation, a room that gets enough natural light from the sun, the room layout that facilitates the movement of residents to activities, the availability of open land to plant crops, etc..
On this occasion I will discuss about building a healthy home with an overview on air circulation and natural lighting in the rooms inside the house.
Air Circulation
Air circulation systems in residential buildings are usually obtained through a vent or vent. For the outermost region of the room using the ventilation building for the air flow, while for a room that middle position of the building can use the catcher channel the wind, or so-called channel or tower wind catchers wind catcher. To create a natural flow of air can vents are usually made in two areas of the wall. The pressure difference inside and outside the building will help the air flow from vents in a single field wall to wall ventilation in other fields. The number of air ventilation in buildings (houses) should be sufficient to support the process of air circulation, fresh air flows from outside into the room.
Form of ventilation is commonly used conventional windows with shutters of the glass or wood panels that can be opened wide during the day. Then there is also a window bouvenlicht, namely glass windows with two blades that have a gap between them that allows the exchange of air. Bouvenlicht usually installed in bathrooms or toilets. There is also the type of window glass Nako with blades of glass that can open the lid. In addition, can also be made air vent grille-shaped air holes with a horizontal arrangement on the walls of the building. Methods to make ventilation holes also vary by making a hole walls, wood frame with horizontal lattice direction, or use the rooster of concrete materials, metal, aluminum or wood.
The best systems are used to design the air circulation system which is a natural cross-ventilation system (cross ventilation), on cross-ventilation air circulation system arranged in such a way that can flow from one point of the air vents to the point of another air vent, and so vice versa. With the pressure difference inside and outside the building, the airflow will not be 'stuck' in the house, which led to the house feels stuffy and hot. Another way that can also be done by creating a garden with voids in the house, garden and voids inside the house will help the air circulation in the middle of the room in the house which is quite far from areas of the wall.
If the use of ventilation air felt still less, then it can be done in ways that alternative active method by adding exhauster ventilation (exhaust fan or blower section wall roof section) which actively with the help of electrical energy will suck and drain the air out of the room, to forced to exchange with fresher air from outside through the ventilation holes.
If your house is in urban areas and conditions in your home is really not possible to use the natural (invoice pollution, density or building a high density level), you can use artificial ventilation systems such as Air Conditioning (AC). Sure must be planned clearly how the capacity and the number of Air Conditioner that will be used. Here's how you can use to calculate AC requirements in a room:
Suppose the size of the room 3m x 4m.
Room width = length of room x width of room
Room width = 4m x 3m = 12 m²
Coefficient BTU (British Thermal Unit) »500 BTU for 1 m² area of the room
Capacity AC = x Coefficient BTU Room Size
Capacity AC = 12 m² x 500 BTU
AC = 6000 BTU capacity
The capacity of the AC standard commercially available, including:
- AC ½ PK capacity equivalent to 5000 BTU
- AC PK ¾ capacity equivalent to 7000 BTU
- Air-conditioning capacity of 1.0 OD equivalent to 9000 BTU
Then the room with an area of 12 m² require 6000 BTU air conditioner with a capacity »¾ Wear AC PK
Since area (L) = 12 m² and air conditioning capacity required is 6000 BTU, should we buy AC ¾ PK. No need to use the AC a PK because of the power dissipation will occur, do not also install air conditioning ½ PK, because the performance is less adequate air conditioning to cool the room.
Exposure
As with air circulation (penghawaan), lighting the room should be rooted in natural light. So in addition to healthy can also save energy. No need to turn on the lights in the daytime. However we are fortunate to live in an area that is rich in sunshine throughout the year. Aside from being a source of vitamin D, sunlight can also serve to kill some types of fungi and bacteria is negative. Natural light (coming from the sun) which came into the room to clean the room once warmed the room to avoid moisture.
Therefore in every room should be made of glass windows related to outer space. In determining the magnitude and location of windows, be aware of the direction of the sun. Direct sunlight from the west will make the room very hot. Use a canopy / overstek windows to shade windows from direct sunlight and keep the ventilation window of splashed when the rainy season.
Window glass is one of the building elements which function as a place of entry of sunlight into the house. It also can be used void in the room that does not allow windows to be fitted, for example because it is limited by the walls of your neighbor's house. Another way is to use a glass skylight or roof tiles or the use of materials on the roof Polycarbonate carpot in your home. The use of bulkhead walls made of glass or glass block can also be categorized as a component of the lighting, as well as one of the architectural ornaments that are widely applied in the design of modern homes today.
Non-Based Planning and Direction Setting Sun
We all understand that the sun moves from east to west for 12 hours every day. Abundant light it can bring many benefits to humans, including at home. But if not handled and used properly, the sunlight it will cause discomfort because of the potential to increase the temperature inside the room. For that there are several ways that can be used to determine the spatial positions and openings under the direction of sunlight.
a. Bedroom
In order for the morning sun can get into this space, put the bedroom in the southeast to northeast. Incoming beam makes you not feel like getting out early. In addition, this side does not receive hot afternoon so convenient if used to rest.
b. Family Room, Guest Rg and Rg Eating
Joint space should be the northwest side or the southwest. In this position, the space will have natural light and warm. But to reduce the heat on the west side, there is need for special processing such as the use of materials or the use of heat shock grid wind.
c. Bathroom
Usually, the bathroom is an area that the level of humidity is high, then the area is best if it gets direct sunlight. Put a bathroom on the west side or east.
d. Kitchen
Kitchen with cooking equipment has the potential to become high-temperature space, then the best option is on the north or south.
e. Space Support / Service
This space is a priority second only to the main rooms have been placed first. The west side of the less comfortable for humans, because it is too hot-the ideal place for washing and drying room, laundry to avoid moisture and dry quickly.
f. Openings
In general, openings such as doors or windows should be located on the north or south because it is not exposed to direct sunlight. If the forced opening of doors and windows are in a position north or south, it can be 'tricked' by installing curtain (shade or blind) at the opening of doors or window glass is the dominant material. So that the intensity of sunlight enters the house or room can be arranged.
Thus the article on planning a healthy home building this time, the next article I will write about living a healthy home planning of the layout design (layout) and sanitation.
