Abstract:
�â� � The task of the designer is to create the best possible indoor climate. The occupants
of the building judges the quality of the design from a physical as well as emotional
point of view�â� � (Koenigsberger.1974)
An indoor environment is required to be thermally comfortable and healthy as the
residence period inside a building has been gradually escalating. The utilization of airconditioning
systems and HVAC devices has been rapidly increasing in current years
and the demand for artificially ventilated systems have elevated around the world. Due
to this reason, energy utilization of buildings and decrease in resources of developed
countries has also amplified drastically. The essential purpose of every built structure
and heating and air-conditioning systems installed in a building is to provide an
atmosphere that is suitable and pleasing, one that does not affect wellbeing or
functioning of the inhabitants.
�â� � The experience of a space is depended on what the user expects from that particular
space or user needs or aspirations. The architect�â� � s role is to realize the aspirations of
the user and create a building that responds positively to those needs �â� � . (Sri Nammuni,
1987).
Thermal comfort is essential for the man to lead a healthy life. Therefore, since the
beginning times, man has tried to create thermally comfortable environments. Thermal
comfort is highly subjective sensation. It is a cognitive indicator, which cannot be easily
converted in to physical tangible parameters. However, thermal comfort can be defined
more qualitatively as the range of climatic conditions which most of the people feel
comfortable, neither cold nor warm.
