Abstract:
The human comfort level depends upon some suitable environmental conditions i.e. temperature and humidity etc. and air conditioning systems help to maintain these suitable conditions. In this study, suitable building design is presented along with the weather conditions of its surrounding. The model of the building was designed using Ecotect software and heating and cooling loads for the structure were calculated. These heating and cooling loads were reduced to about 53% using passive techniques for the building design. A vapor absorption system was designed based on these reduced heating and cooling loads with proper specifications of each working component. Also, a comparison of VAS and VCC was made based on their cost as well as their environmental effects and a suitable conclusion was made in this regard.
Introduction:
Human comfort depends upon the environmental conditions of the surrounding. Certain environmental conditions are much more suitable to humans i.e. 20oC -20oC temperature and humidity level of 40%-60%. as compared to other environmental conditions. To obtain such conditions, scientific methods are available. Also, developing countries like Pakistan face much of the power crises, to attain human comfort in the presence of such crises passive techniques are available which helps to reduce the cooling and heating loads of the structure. In this complex engineering problem, such passive techniques are presented along with the design of the vapor absorption system which is one of the major sources of human comfort these days.
In the first part of CEP factors affecting the heating and cooling loads of building are provided along with a building was designed for weather conditions of Karachi, Pakistan. The building model was a replica of the original building. The heating and cooling loads for the given model were calculated using Ecotect software. Initially, the building was designed using general materials. Based on these heating and cooling loads the tons were calculated for the model. In the second part of CEP passive techniques were applied to reduce these heating and cooling loads to about 50%. For this purpose, insulating material was used in the walls, ceilings, roof, and floor of the building. Moreover, double glazed windows were also used for this purpose along with the proper orientation of the building.
