The need for Human comfort:
We experience mental and physical fatigue resulting from activities of the day. Hence it is essential that our mind and body recovers through recreation, rest and sleep to counterbalance this physical and mental fatigue.
This cycle can be disrupted by unfavourable climatic conditions and resulting stress on the mind and body causes discomfort, loss of efficiency and breakdown of health.
The effect of the climate on health is, therefore, a factor of considerable importance. Climate continues to influence architecture design.
The climate of a region changes over a period of time along with daily variations in weather. Climate is the product of the geographical factors of the area we live in. It depends on the variable factors such as temperature, precipitation, vegetation and invariable factors such as latitude, longitude, nearness to the sea etc. Hence there may be a difference between the microclimate and macroclimate of a region. Hence we have to keep a design approach which considers the environmental factors and human comfort.
When we talk about thermal comfort, we talk about the comfort of human beings in terms of temperature and humidity.
But why do we need to think about temperature and heat?
The human body is continuously converting food that we eat into energy. Also, we are continuously breathing in and breathing out. Oxygen in the air gets mixed with the blood and the byproduct is heat and humidity.
