Abstract
This paper deals with the human adaptability to its built environment. The built environment as we know it rarely finds itself adapting to its surrounding context, whether it be on the level of interaction with humans or the climate. Humans and nature both are in a constant state of flux; moving, changing, sensing, and reacting to their context and information they gather and perceive. A barrier is formed between the built environment and humans and nature due to the fact that their inherent characteristics are utterly contrasting. It is commonly estimated that persons in urban areas spend at least 80% of their time indoors. This suggests that the quality of the indoor environment can have a significant impact on comfort, health, and overall sense of well being. The indoor environment of buildings should thus be designed and controlled, as to provide a comfortable and healthy space for occupants. In order to maintain the quality of the indoor environment, we mechanically condition our buildings to achieve constant, uniform and comfortable environments. The maintenance of thermal equilibrium between the human body and its environment is one of the primary requirements. History of thermal comfort and climate design shows a definite relation between them and research is needed to know “What are comfort conditions?” and “How buildings could adapt themselves to these conditions”.

Physiological adjustments include changes in the physiological responses that result from exposure to thermal environmental factors leading to gradual diminution in the strain induced by such exposure
Summary
The phrase built environment refers to the man-made surroundings that provide the setting for human activity, ranging in scale from personal shelter to neighborhoods to the large-scale civic surroundings. Thermal comfort is essentially a subjective response Current comfort standards such as ASHRAE-55 (American Society of Heating, Refrigerating and Air-Conditioning) [1] define thermal comfort as “state of mind, which expresses satisfaction with the thermal environment”. While it may be partially influenced by a variety of contextual and cultural factors, a person’s sense of thermal is primarily a result of the body’s heat exchange with the environment. This is influenced by four parameters that constitute the thermal environment (Airtemperature, Radiant temperature, Humidity and Air speed) two personal parameters (Clothing and Activity level, or Metabolic rate) [2]
