Ole Fanger and Jrn Toftum International Centre for Indoor Environment and Energy Technical University of Denmark Abstract This paper predicts some trends foreseen in the new century as regards the indo

3、or environment and thermal comfort. One trend discussed is the search for excellence, upgrading present standards that aim merely at an “acceptable” condition with a substantial number of dissatisfied. An important element in this connection is individual thermal control. A second trend is to acknow

4、ledge that elevated air temperature and humidity have a strong negative impact on perceived air quality and ventilation requirements. Future thermal comfort and IAQ standards should include these relationships as a basis for design. The PMV model has been validated in the field in buildings with HVA

5、C systems that were situated in cold, temperate and warm climates and were studied during both summer and winter. In non-air-conditioned buildings in warm climates occupants may sense the warmth as being less severe than the PMV predicts, due to low expectations. An extension of the PMV model that i

6、ncludes an expectancy factor is proposed for use in non-air-conditioned buildings in warm climates. The extended PMV model agrees well with field studies in non-air-conditioned buildings of three continents.

7、xcellence Present thermal comfort standards (CEN ISO 7730, ASHRAE 55) acknowledge that there are considerable individual differences between peoples thermal sensation and their discomfort caused by local effects, i.e. by air movement. In a collective indoor climate, the standards prescribe a comprom

In the future this will in many cases be considered as insufficient. There will be a demand for systems tha

9、t allow all persons in a space to feel comfortable. The obvious way to achieve this is to move from the collective climate to the individually controlled local climate. In offices, individual thermal control of each workplace will be common. The system should allow for individual control of the general thermal sensation without causing any draught or other local discomfort.A search for excellence involves providing all persons in a space with the means to feel thermally comfortable without compromise.
