Urban Ventilation

Introduction

The current issue in today is about the heat that is distracting and disturbing to the people, both in households and corporate world. Because of the effects of climate change, every country faces a different kind of heat – more than the usual. The identified causes are from the emitted carbons came from the vehicles, or the chlorofluorocarbons from the refrigerants. Apparently, the simple living of the people became the simple gesture to destroy the nature. If the situation continues, it only predicts that there is a peril to abandon the humanity. Due to the past years abuse in nature and the time has finally arrived for the consequences and now the country is looking for a better way to cool down the urban heat. For them, it is only possibility if they managed to gather more wind and directly deliver it to the city. Through thinking this kind of dream, it’s only closing to the fact that it is impossible.

Urban Living

The quality and lifestyle of the individuals living in urban creates a demand to place an initiative to address the issue of unusual heat that affects all the living things on earth. Living in the urban environment, the ventilation is needed to fight the heat. The effect of heat reached the livability and health of people therefore there is a formulated recommendation that builds the permeability and separation of the buildings to open the ventilation. To have the attractive and comfortable living, the sustainable buildings should be integrated to improve the urban climate. Through the process of enhancing air ventilation, mitigating heat island effect, decreasing polluted runoff and air exhaust emission, the quality and comfort in urban places can be enhanced. It is expected the urban ventilation provides, natural/green space and other physical amenities for pedestrian/neighborhood benefit and enjoyment. The “sustainable building” provides access to daylight and natural ventilation in primary interior spaces to contribute to the physical and mental health and wellbeing of building occupants. It allows for accessibility and flexible use of space to meet social and community needs and to enhance social integration and equity. Through the continuous development of the sites will appear to have the wall effect in which the air can penetrate. However, there is a need for a large to manage this kind of project. There are also special circumstances such as the physical location, immediate environs and conservation of heritage of a development site as well as particular functional requirements may render the compliance impracticable or impose unjustifiable hardship that needs to justify before establishing the sustainable buildings (Wong & Ng, 2009).

Implications of Urban Ventilation

The potential of using natural ventilation for indoor thermal comfort in residential buildings are based on climatic data analyses. The characteristics of weather data for a typical year were analyzed with regard to temperatures, wind speeds, and wind directions. Thermal comfort models for natural ventilation can be applicable for use. It was found that by applying natural ventilation, a thermally comfortable indoor environment can potentially be provided for a large number of hours in the year with optimum of facade designs for residential buildings (negligible heat sources) (Liping, & Hien, 2007). Evidently a great deal of energy (and money) can be saved by relying on natural ventilation to achieve thermal comfort in warm weather, rather than install air conditioning, and this is quite feasible in the relatively mild climate of most European countries. The final part of the book therefore considers strategies for natural ventilation, including specific devices for natural ventilation (such as operable windows, louvers, vents, stack ducts, wind catchers, chimneys and double-skin facades). The sizing of these openings may be critical, particularly when ventilation is induced by stacks. Experimental determination by models is often the best approach (Architectural Science Review, 2006).

Conclusion

Through the different explorations of the environmentalists and the advocates in the other consequences pertaining to the climate change, people are the only creation that is the cause and will endure the effects of their negligence. The most affected area in the issue of climate change is the agricultural sector in which most of he people are dependent in the said sector. However, the creation of certain strategies to lessen the impact of the climate change is promoted in both rural and urban areas. The government called the action for adaptation as an important aspect of creating recommendations on how to cope with drought and biological diversity. The indigenous people have is more capable to survive for they cope with the environment and can help warn the experts on the upcoming other consequences of climate change.
