Appendix B - Energy Policy <br />Attachment <br />From American Society of Heating, Refrigeration <br />and Air Conditioning Engineers (ASHRAE) Standards <br />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 <br />not the same for everyone. However, extensive laboratory and field data have <br />been collected that provide the necessary statistical data to define conditions <br />that a specified percentage of occupants will find thermally comfortable. <br />httg://industries.bnet.com/whitepaper aspx?scname=Plumbing+and+HVAC+E <br />guigment&docid=114190 <br />2. This standard specifies the combinations of indoor space environment and <br />personal factors that will produce thermal environmental conditions <br />acceptable to 80% or more of the occupants within a space. The <br />environmental factors addressed are temperature, thermal radiation, humidity, <br />and air speed; the personal factors are those of activity and clothing. <br />http://www.constructionbook com/xa/ASP/ProductlD 3695/id 402/sublD 636/gx/ <br />default2.htm <br />3.
