主　　题：Indoor environmental quality(IEQ) Sensors Continuous monitoring Graphical user interface Interactive feedback 

摘      要：Indoor environmental quality(IEQ)significantly affects human health and ***,continuous IEQ monitoring and feedback is of great concern in both the industrial and academic ***,most existing studies only focus on developing sensors that cost-effectively promote IEQ measurement while ignoring interactions between the human side and IEQ *** this study,an intelligent IEQ monitoring and feedback system-the Intelligent Built Enviroment(IBEM)-is ***,the IBEM hardware instrument integrates air temperature,relative humidity,CO_(2),particulate matter with an aerodynamic diameter no greater than _(2.5)μm(PM_(2.5)),and illuminance sensors within a small *** accuracy of this integrated device was tested through a co-location experiment with reference sensors;the device exhibited a strong correlation with the reference sensors,with a slight deviation(R^(2)0.97 and slopes between 1.01 and 1.05).Secondly,a wireless data transmission module,a cloud storage module,and graphical user interfaces(i.e.,a web platform and mobile interface)were built to establish a pathway for dataflow and interactive feedback with the occupants of the indoor ***,the IEQ parameters can be continuously monitored with a high spatiotemporal resolution,interactive feedback can be induced,and synchronous data collection on occupant satisfaction and objective environmental parameters can be *** has been widely applied in 131 buildings in 18cities/areas in China,with 1188 sample *** these applications,we report on the targeted IEQ diagnoses of two individual buildings and the exploration of relationships between subjective and objective IEQ data in detail *** work demonstrates the great value of IBEM in both industrial and academic research.
