HOUSING AS CLIMATE
HOUSING IN THE HUMID TROPICS is impossible and unlikely to define a model home as a correct type for the production of housing in wetlands and in any area. It all depends on various factors such as the presence of suitable materials or harmonious with the environment, traditional customs, economic status etc area.
is why one of the traditional forms of housing construction since the colonial era was the use of Bahareque and Tapia were widespread nationally due first to the low cost of materials (wooden rods earth or bamboo and straw), second to the easy way to get and build without the need of sophisticated equipment with little labor without But this tradition has been abandoned due to non completion of construction plaster called what was left unattended wearing unattractive and also due to the industrialization of building materials that are more accessible because of its low cost of these in the past, but again turned by 180 ° due to imports of machinery and price gouging by the high demand overcrowded housing projects by successive governments, which instead of promoting self-management of construction as was done for years 40 of the MSAS health program to eradicate the chip carrier of Chagas disease, we chose a solution contrary to the requirement population and speculative mechanisms for votes.
sanitation campaign in a group of doctors, engineers and architects are dedicated to the task of forming a housing construction project starting from the preparation of blocks (adobones) with rudimentary molds to employment-based ceilings cakes (earth and straw) which were then again by the government to turn replaced by sheets of zinc without take into account that your application provides unfavorable due to high absorption of heat that they retain and transmit to the inner area of \u200b\u200broom.
today because of the difficult situation being experienced by the country should return at least the designs of old houses, re-employment of these customs of traditional architecture and the advantages they once had the house demolished and Pastor in Caracas.
On the other hand, the tradition of the walls was a counterproductive because of the fragility of its walls against earthquakes, as this system comes from the English conquest and was a system imported from Europe where there practically seismic zones.
Moving on we have the basic elements of topology for the production of housing in humid areas are:
ceilings steep slope, as this facilitates more rapid runoff of rain and the sun is not so much because one of its wings is in shadow. The wings should be bigger in order to prevent erosion and wear of the walls due to the constant rain of these areas, as well as providing shade on it, that slow heat absorption effect. The walls must be thin to prevent the moisture is retained for a long time and must be vented to allow air circulation and thus eliminate environments with high concentrations of moisture. It is always advisable to build the houses raised off the floor to avoid contact with the ground as this has a high degree of moisture retained. Although there today insulation is always advisable to clear the ground naturally allowing the passage of wind speed evaporation in these floors. One way to improve housing in the humid tropics is to create zenith ventilation, either by the use of skylights or roof breaking way to create different levels of tilt.
When it is intended to build a future and this is valid for all types of housing with reduced land, we must begin with the top, leaving the space below and not otherwise first because the constructive discomfort at are much lower and second that the investment is much more economical because it is structurally almost complete.
HOUSING IN TROPICAL DRY
A good part of our lives we spend in our homes but we never thought about because it is called non-housing and shelter weatherproof.
Because if we analyze the word, we know that a home is that "experience", "living" is part of our lives and yet we do nothing to make it part of us but we are content to be beautiful, fit our and most things important as low cost, but psychologically and physically we're running slowly.
I am convinced that housing is closely related to our well being and therefore mental health is the ruler of the body. So in these areas are fundamental priority solve welfare problems that can make the experience more pleasant in our homes without profit facilities that exist today that far from solving community problems harms.
A good home builder and an observant person with simple knowledge of physics, you can and it has shown through history that can solve simple problems tactics and good use of materials and low technology to ensure that their housing is an organic element that can regulate the variables that affect an area at a given time. To breathe with us, we do not feel winded.
A basic concept we all know is that hot air is lighter than cold air and when these are found, the hot air tends to rise as the cold air moves quickly to take the place of this occurring under the we call air currents or winds.
This concept is beginning to achieve through simple elements that produce changes within a hot zone, such as to create shadows that cool though slightly a part of our house.
example, if we have a housing with an inner courtyard full of vegetation and that this occurs in shadow areas, we are automatically producing air currents in the yard which we can take to lead in the environments of our homes, cooling of Thus within these spaces in relation to the outdoor area. To this we must learn to control the directions of the winds bring dry air central courtyard area with openings against wind direction can make a stream of air temperature will gradually decrease as the pass by the environments. Only a matter of distributing cooler space for the most important sites for housing as the rest area for example, and the use of ventilation as romanilla items or blocks drilled to allow air flow to penetrate the most possible in all environments. The rest is a matter of good design to make it nice, because the architecture is that, used properly spaces the function for which it is created and used items to be visually pleasing as the man also lives sensations.
nature can help with the temperature change if this court add a fountain or waterfall, we get some moisture, main influence on the temperature of an environment. Not necessarily the use of the courtyard is the only element to use, often for reasons of space we can use a method like that used in the Middle East such as wind catchers that serve the same function but in a smaller space. ( discuss this issue in the near capítlo )
But these concepts can be used not only individually, we must also build on the elements that surround us in the case of a community in which the walls of the neighbor also become architectural elements to which we must make the most and the height of neighboring buildings. all is a matter of logic to use when building.
often said that in dry, flat roofs can be built because the surface is smaller than a gabled roof addition that as rainfall is almost not needed little drain quickly. However sometimes the sacrifice of one thing compensates the other and in this case the use of pitched roofs is completely valid and that any water or roof planes will always be in shadow.
many and in most of the houses in dry indoor environments there are always times more concentrated heat that in the outer zone, this is due to the following reasons:
The roof and / or the walls are too much radiation as the material absorbs and transfers this heat to the inner zones. There are not enough openings for escape of internal heat, so that hot air envelops the entire room. The construction components have little reflection of sunlight also because of its color.
Note that to remove the internal heat is necessary to create air circulation. By opening openings should be aware that these are, first of the majors are where the cool wind direction and the output comes to be smaller to create acceleration of output current (early of thermodynamics). Example Look at the design of a turbine of a jet propulsion where the entrance hole is considerably larger than the output by the rising heat of combustion to create propulsion in this case and move the large mass of the airplane.
Another element for cooling the internal areas and on the basis that the mass tends to warm up and cool down is the use of underground vents as in the example of placing a deep tube to get the area fresh groundwater that reaches the solar radiation by placing two openings. A near ground level and protected against the ingress of water and animals on the outside and the other to the site to air, also placing in the bottom of a wall, thus ensuring a hot air circulation through this which will be cool and fresh air into the room. To ensure this movement is necessary to have a small opening at the other end of the room to ensure the internal circulation.
