USER PERCEPTIONS OF INDOOR AIR QUALITY IN A RANGE OF LARGE-SCALE FACILITIES, WITH NATURAL AND MIXED-MODE VENTILATION - FIELD STUDIES IN AUSTRALIA, GERMANY, NEW ZEALAND, AND SINGAPORE

摘要

This paper describes the results of field studies in which the occupants of eight academic and office buildings,located in New Zealand, Australia, Germany, and Singapore were surveyed about their perceptions of the quality of the air in their premises, using the Probe-type questionnaire. Following a brief description of the buildings, all of which were designed to provide natural or mixed-mode ventilation, the paper outlines the occupants' perceptions of a range of air quality issues, as well as their overall comfort, health, and productivity. The results indicated that while most of the temperate zone buildings achieved better than benchmark scores, the challenge remains to improve the perceived freshness and odour characteristics of the air, and the perceived influence on the occupants' health.
