document: Modelling user acceptance of building management systems This study examines user acceptance of building management systems -LRB- BMS -RRB- using a questionnaire survey . These systems are crucial for optimising building performance and yet it has been widely reported that users are not making full use of their systems ' facilities . Established models of technology acceptance have been employed in this research , and the positive influence of user perceptions of ease of use and compatibility has been demonstrated . Previous research has indicated differing levels of importance of perceived ease of use relative to other factors . Here , perceived ease of use is shown generally to be more important , though the balance between this and compatibility is moderated by the user perceptions of voluntariness
