About Human Boundary Conditions

Human boundary conditions specify the metabolic activity, clothing insulation, and radiation behavior for the human models in a human comfort simulation.

Defining Human Boundary Conditions

You can control the following aspects of the human models in a simulation:

  • Clothing insulation level, which is a measure of the thermal insulation provided by clothing. It is expressed in units of clo. Common clothing insulation values are available from many sources, including https://en.wikipedia.org/wiki/Clothing_insulation.
  • Metabolic rate, which specifies the heat generation per unit area on the surface of the body. Some common values are 0.7 met for a sleeping human, 1.0 met for a seated human, and 2.0 met for a walking human. Metabolic values for a variety of human activities are available in the ASHRAE Standard 55-2010 handbook.
  • The surfaces that represent the human boundary condition. When you select surfaces, they do not need to be contiguous or to form a closed volume.
  • Similar to walls, surfaces representing the human boundary condition can be subject to surface-to-surface radiation and solar radiation, and you can specify their radiation parameters.
