1Task 1 (a) (LO 3: 3.1)About human comfort levelIn every place, the human comfort level exists. In car, there is a human comfort. For buildings, such as homes and offices, etc may have human comforts. They will require more than any other places. And, the choices of human comfort for themselves may be different. Some people wish to wear sweater and others go to shorts. And so, many people need ear-splitting music while go for silence. In those differences, it is the nature of comfort that needsto understand which it is the phenomenological. For our humans, there are five types of senses. They are (1) touch(2) sight(3) hearing(4) smell and,(5) taste.Each one of these senses can lead to lesser or greater degrees of comfort which canact independently. As an example, our sensation of cold will be overwhelmed that we are suffered literally shut down of our somebody functions but sometimes we tolerate uncomfortably for a pleasurable experience such as standing in a rain and walking while snowing, etc. But, when the discomfort is approaching extremely such as North pole and South pole of the world, the normal people who don’t born that region could be got serious problems.Figure 1 and 2: Humans maintain comfort in very diverse climates.In human comfort, the thermal comfort is the most requirement.
2Thermal comfortTemperature is the significant component to experience the comfort in a place. Our body can perform an internal temperature range narrower than the external temperatures. In that time, our metabolism generates heat and dissipate into the air. When the temperature is high, the process becomes difficult and we may suffer warm. When external temperatures are low, the rate of heat loss becomes more rapid and we feel cold.Surfaces of a roomWhen the thermal comfort is in a confined space, we have to examine that all of the temperatures in the room and the distribution of heat in that room. The mean radiant temperature entails averaging the temperatures of each surfaces in the room. With the combination of air temperature, produces the overall measure, the mean operative temperature. But it has a limitation as how close a person will be to a particular surface is usually variable and so the different surfaces will dominate at different times.
