The Building Occupants Survey System Australia – BOSSA – is a web-based survey tool to assess occupants' satisfaction with the IEQ performance of their office building.


BOSSA has been developed with an integrated, flexible branching structure. Core questionnaire items ask building occupants to rate their overall satisfaction on key IEQ dimensions, including:


Indoor Air Quality and air movement 
Spatial comfort
Noise distraction and privacy
Connection to outdoor environment
Building image and maintenance
Individual space
Thermal comfort
Visual comfort
Perceived Productivity


BOSSA is endorsed for use in the National Australian Built Environment Rating System (NABERS IE), Green Building Council of Australia (GBCA) and NZ Green Building Council.


The University of Sydney and the University of Technology, Sydney developed BOSSA and the tool was funded by the Australian Research Council (ARC) and Industry Partners (Brookfied-Multiplex, Investa, GPT, Stockland and ARUP).
