Another aspect that makes the personal factors verydifficult to predict and is becoming more prevalent in modern construction isthe need for multi-purpose buildings. Multi-propose buildings have becomeattractive as they offer a much larger target of use and much higher revenue inmost cases. In modern construction for example, many cinemas are now beingbuilt with the tools needed to hold professional meetings. This makes it muchmore difficult to determine the personal factors as the building may be usedfor differing functions meaning that the work rate and clothing of its usersalso vary. Someone eating popcorn in comfortable clothes may experience adiffering level of thermal comfort than a professional in a suit having to talkloudly for prolonged periods of time.
After all, the more we insulate ourselvesthrough clothing and increase our work rate the more we naturally produce heatin our bodies which could be crucial in thermal comfort. Given all the information provided, we can now go back andre-evaluate the original statement that human thermal comfort is ultimatelydependent upon six simple parameters that can be measured and assessed for anyindividual in any particular environment, which allows us to design buildingswithin which all occupants will be thermally comfortable. From the evidence itis clear that measuring the human thermal comfort level is a simple process, inmost cases all that’s required is to ask the individuals using the area or justexperience it for yourself. Simply asking whether the air feels hot or cold canquickly establish what changes must be made. If people are complaining aboutthe heat, then perhaps it’s time to turn down the radiator and open a window,if you can. But if every individual in the same area is experiencingdiffering levels of human thermal comfort, then any change will surely affectsomeone else’s thermal comfort in a negative way. This may be because some hadbreakfast and some didn’t, some walked to the location and some didn’t or maybejust because they arrived at differing times.
The environmental factors faroutweigh the personal factors and if all of those factors are maintained andmonitored then the human thermal comfort levels should remain at a highstandard. So in conclusion, yes, human thermal comfort is ultimately dependenton six parameters, four basic, assessable, easily measurable factors along withtwo impossible to assess, impossible to manage factors. This allows us todesign buildings within which most occupants will be thermally comfortable.
