Thermal comfort is that condition of mind that expresses satisfaction with the <br /> thermal environment. There are large variations, both physiologically and <br /> psychologically, from person to person,which makes it difficult to satisfy <br /> everybody in a space. The environmental conditions required for comfort are not <br /> the same for everyone. However, extensive laboratory and field data have been <br /> collected that provide the necessary statistical data to define conditions that a <br /> specified percentage of occupants will find thermally comfortable. , Deleted:http:/findustdes.bnet.com/whitep.perl <br /> 2. This standard specifies the combinations of indoor space environment and nt&docid=114190 <br /> personal factors that will produce thermal environmental conditions acceptable <br /> to 80% or more of the occupants within a space. The environmental factors <br /> addressed are temperature, thermal radiation, humidity, and air speed;the <br /> personal factors are those of activity and clothing. <br /> http://www.constructionbook.com/xo/ASP/Productl D.3695/id.402/subi D.636/ax/def <br /> ault2.htm <br /> 3.
