Displacement ventilation environments with chilled ceilings: thermal comfort design within the context of the BS EN ISO 7730 versus adaptive debate.

Describes the current design standard BS EN ISO7730 - 'Moderate thermal environments - determination of the PMV and PPD indices and specification of the conditions for thermal comfort'. States that it is based on Fanger's work and comprises a steady-state human heat balance model that leads to a prediction of the sensation of human thermal comfort for a given set of thermal conditions. Questions the applicability of this standard when confronted with the more complex environment of a chilled ceiling operated in combination with displacement ventilation.
