Climate Issues and their Effects on Architecture

Chapter 6

Decision

Architecture has to accommodate to the local clime, particularly the tropical clime has changeless rainfall and sunshine throughout the old ages. In fact, the tropical clime has a comparatively comfy temperature. But the sunshine could be intense sometimes. In this context, the inactive design should in line with the tropical clime to heighten the indoor thermic comfort in order to forestall the indoor temperature become higher than the out-of-door temperature.

The design of the auditorium has to be sensitive to the climatic specialnesss and the site context ; in this context, it is able to supply passively comfy status for the residents. Climatic issues have to set in serious history in order to make the auditorium edifice envelope that are thermally comfy and bring forth the least impact on the environing environment.

With the consequence and influence of “Global Warming” and the escalating monetary value of electricity, maintaining the indoor to be cool will turn as an of import issue in the hereafter. The largest energy consumer in the edifice, particularly the auditorium is the air-conditioning system. However, the air-conditioning system besides has the largest nest eggs possible sing to this issue.

The 2nd largest energy consumer in the auditorium is the illuming system. When unreal lightings are runing, it consumes electricity and generates heat into the indoor infinite. Therefore, the energy ingestion is increased as there is a demand for more cooling burden.

For an enclosed edifice like an auditorium, other steps are resorted, like the energy-efficient electrical contraptions. For illustration, energy-saving lightings, high efficiency air-conditioners and last but non least, the sophisticated edifice services control system.

However, before sing neither the electrical contraptions nor the chilling system, a inactive method should be the get downing point to supply an efficient edifice envelope. Assorted architectural solutions have been used in the tropical clime to chair the consequence of the intense Sun on the auditorium design. Orientation of the edifice, light colour wall pigment, proper shadowing devices and the well-insulated edifice envelope.

The design of the auditorium, which integrating the inactive methods should be adhered to before put ining the energy efficient mechanical and electrical edifice system. It is decidedly assisting to cut down energy ingestion in a right manner.

Material like the polished aluminum sheet used as external facing is a fillip point as thermic insularity in the tropical clime. It has high value of coefficient of reflection and aesthetically nice in looking. If the budget is allowable, insularity bed can be put in the wall building and a plaster board on the internal wall surface as a dual insularity bed. Additionally, mineral wool and fiber board have a positive influence on the OTTV analysis. It has been found that utilizing insularity can heighten the internal comfort status by increasing the thermic opposition of the wall. Surprisingly, the dual wall system for the auditorium is non the best system in the tropical clime.

If there is budget restraint, a simple brick wall building with 13mm thick plaster applied on both sides of the wall of the auditorium can run into a satisfactory degree. White coloring material is ever the best coloring material for the tropical clime.

Besides, dual glazed clear glass with low-e is the best glazing which suit to tropical clime. Double glassy glass should be the pick of glazing type for the auditorium as it depends to the full on the air-conditioning system. It is really of import to protect the window from direct solar heat addition.

The gaps of the wall should take into serious consideration. Opening at East-West lifts must be avoided as it brings in direct heat and serious solar radiation. If the gaps are ineluctable for the East and West lift, shadowing devices should be attached to supply the proper shading consequence. By agencies of suited shadowing devices aid relieve the comfort status in the auditorium. In this context, the horizontal shading devices suit for East and West lifts while the perpendicular shading devices are the better option for North and South lifts.

Proper pick of edifice stuffs can cut down the solar radiation penetrates to the internal infinite of the auditorium. It is really important for the auditorium in tropical clime. Materials with low thermic transmittal and low heat capacity are the most preferred to forestall the heat accumulate in the edifice envelope during daylight. The heat, which accumulated would radiate into the internal infinite of the auditorium in the dark when the air current velocity tends to be lower. Consequently, hot air temperature and high humidness caused hapless indoor air quality in the auditorium. When there is a map in the dark, it utilizes more energy in order to unclutter the unwanted air in the auditorium.

As the UBBL is amended to follow with OTTV computation at the design phase before the building, construct environment in Malaysia is now concerned about a more energy-efficient and sustainable edifice, in term of the building stuff, edifice design, energy efficient edifice services and contraptions and so on. Now the to the full active manner edifice like auditorium is deriving its attending to be a green edifice. There will be lesser and lesser energy wastage created by auditorium in the hereafter.

The smart system like the Building Automation System ( BAS ) in the auditorium should be implemented good. It would be ineffectual if no 1 to supervise the uninterrupted public presentation of the edifice system. The BAS system needs regular monitoring and bettering the position quo. The Energy Management System ( EMS ) is now a tendency for energy efficient edifice. On the other manus, renewable energy is now a manner frontward in order to prolong the ecological environment. It is particularly of import for the auditorium, which consumes higher energy than the other type of edifices.

A sustainable auditorium is of import as it leads the betterment to the other to the full active manner edifices like the shopping complex and hotel. The probe and surveies done on the sustainability of the auditorium are for the endurance of thuman in the hereafter. The physique environment which helps planetary heating should be reduced.

DIRECTIONS FOR FUTURE STUDY

It is undeniable that the figure of surveies and publications on the relationship of clime to architecture, people and energy usage is really extended. Undoubtedly, a assortment of theoretical and proficient jobs should be solved before a existent ecological architecture can be created in the tropical states.

In order to hold the decision of future surveies even more useable, different auditorium should be tested to obtain more complete informations sets. Additionally, it is advisable to utilize questionnaires as parallel subjective surveies to acquire the subjective comfort informations.

Future surveies can include a more elaborate survey of the hair-raiser works room control, included more informations from the hair-raiser operation on the behavior of the rooms’ airing systems.

In a nutshell, the probe of this survey was limited to merely one instance survey auditorium. Further surveies on assorted instances of auditorium in Malaysia are recommended to derive more accurate rating.
