COMF 4 - Thermal Radiation: Radiant Barriers, Radiant Heat, Comfort, & Myths

Wednesday, April 29, 2009  ·  8:30 AM - 10:10 AM

Of the modes of heat transfer, radiation is the most complex and, therefore, usually misunderstood. In buildings, thermal radiation is always present in various components and can almost never be neglected. For example, the solar gain through roofs and windows dominates the cooling loads during the cooling season. While the sun is the major thermal radiation source interacting with a built environment, radiation exchange involves many other sources such as all exposed surfaces (internal and external) of a building, surrounding surfaces (ground, other buildings), clouds, night sky, etc.,.

 

This session will address the fundamentals of thermal radiation and how they apply to buildings. Some of the topics that will be covered include radiation barriers, fibrous and reflective insulation in walls, radiant heating and cooling, and the role of color on surfaces.

 

By attending this session, participants will

 

1. Understand the basic principles that govern thermal radiation
2. Determine where thermal radiation takes place in a house
3. Learn when and how to deal with radiation in a house
