Energy efficient building design strategies for hot climates construction essay
For example, it can apply to the side of a hill, a valley or a portion of the built area, and is characterized by more or less marked changes in temperature, relative humidity, wind, sunshine, etc. Intelligent use of the available natural materials such as inorganic materials e.
Passive design strategies for moderate climate
Instead these countries can choose to base all future development on the principles of sustainability8. This low-pressure zone continues a certain distance beyond the building, depending on the wind velocity, as illustrated in figure These functions involve: 1 controlling the passage of light, 2 controlling the air flow, 3 reducing the temperature of the air current, 4 increasing the humidity of the air current, and 5 ensuring privacy. At that time coal was the only fossil energy source used. In the areas of An-Najf and Al-Kufa in Iraq, where air temperature is very high in summer, people live in basements ventilated by small holes in the ceiling and a malqaf with a very small inlet. The production of glass also causes immense GHG emissions because its production is very heat energy intensive, but glass can also help to save and gain energy if it is utilised in an appropriate way, not according to the present architectural fashion. The difference in energy use between two choices should be adequately reflected. This angle varies 15 degrees per hour, is zero at noon and has positive values in the morning and negative values in the afternoon for example: at 10 a. The roof If the outdoor air temperature is higher than the indoor temperature, the outer surface of the roof exposed to the sun is heated as it absorbs radiation, and, being in contact with the outside hot air, also is heated by conduction. All organic fibers, such as the wood of a shanshool readily absorb, retain, and release considerable quantities of water. Forty years to redesign the energy systems of our existing settlements and less than twenty to learn how to design all the new ones in a different way. The main advantage of this approach is that the system need not be physically built to predict its behavior ASHRAE,
Output response, or dependent variables, which describe the reaction of the system to the input variables. The slats are often movable so the angle can be changed.
Sustainable construction practices in the developing world have to be achieved as soon as possible, because the building and construction sector in these countries is growing very fast.
Generally, as a method becomes more complex it becomes more accurate. The production of cement, steel, glass, aluminium and baked bricks, which are the basic building materials for most modern constructions, have very high environmental impacts, consume the most energy and cause the majority of the GHG emissions in the construction sector5 because their production requires the processing of mined raw materials at a very high temperature.
In the areas of An-Najf and Al-Kufa in Iraq, where air temperature is very high in summer, people live in basements ventilated by small holes in the ceiling and a malqaf with a very small inlet. The balusters and interstices of the shanshool have optimal absolute and relative sizes that are based on the area of the surfaces exposed to the air and the rate at which the air passes through.
Forward models The objective is to predict the output variables of a specified model with known structure and known parameters when subject to specified input variables. Our task is to transform, with some sort of genetic engineering, our carnivore — the fossil energy based city — into a herbivore, the renewable energy based city.
