The need of building occupants for ventilation has been recognized many centuries ago; however, since the early 1970s, ventilation systems for buildings and transport systems have considerably evolved. This was invigorated by researchers who demonstrated the requirements for buildings to provide comfort and good air quality indoors (e.g., Fanger, 1972; Fanger and Christensen, 1986; Fanger, 1988...

For sedentary activities, the PMV equation, derived by Fanger, is mainly based on research of Nevins et al. (720 test subjects). Nevins' experiments were later repeated but with 128 college-age Danish subjects and elderly subjects, instead American subjects. Rohles did from again, over a more extensive temperature range more, namely 1600, Rohles' results have been partly included in derivation ...

This study investigates the applicability of User-DefinedFunctions (UDFs) for determination of thermal comfort indices for non-uniform environments. The demand for such an investigation derived from the need to evaluate thermal environments in aircraft cabins in a more comprehensive way. It is normal practice by Airbus to determine the initial layout of ventilation systems also on the basis of ...
