Appraisal of indoor environmental quality (IEQ) in healthcare facilities: A literature review

This study reviews the relevant literature to ascertain the extent to which IEQ performance evaluation in healthcare facilities have been carried out. The aim is to draw understanding and to identify areas that are yet to be considered or needs more attention. The performance assessment of IEQ is based on four parameters. However, these parameters of IEQ have not been validated as a measurement construct for the evaluation of IEQ performance in buildings. Combinations of subjective and objective assessment methods of IEQ is also limited in ascertaining the degree of variation or equality in their measurement of the same trait factors.
