Background: Productivity is vital in the workplace. Numerous studies endorsed by scientific community affirm that biophilic design in workplace improves productivity. In previous conducted research studies, biophilic design was only evaluated with well control Indoor Environmental Quality (IEQ). The World Health Organization (WHO) reported that nine out of 10 people breathe polluted air. However, how biophilic design behaves in an inadequate IEQ workplace is still not well addressed. Objective: To gain additional knowledge about the impact of biophilic design on productivity (creativity) and cognitive performance in a working environment with limited quality. Methods: The dissatisfactory IEQ site was selected through on site data analytics, of which data were collected by a low-cost loT based indoor air quality monitoring system. Recruited participants will be engaged in this study, with a standard body, non-smokers and non-sensitive groups. Selected plants are applied as biophilic design. The environmental parameters and human behaviours are measured by the developed indoor air quality monitoring system and various wearable devices. The productivity ability is measured by exercises designed by Cambridge University Brain Science lab. The simulation task could be typing (information processing work). The creativity is measured by Taxonomy of Creative Thinking Method. The simulation task could be mind map (knowledge creation work). Cognitive performance is assessed by visual reaction time task, stroop task and visual backward digit span task etc. Results: Multiple data sources collected from various wearable devices are analyzed to measure human reaction to biophilic design. The adopted methodology to assess biophilic design on site will be also defined. An loT based indoor air monitoring system was developed for environmental assessment. Conclusions: Effects of the biophilic design for the people's effectiveness at work is discussed, by considering multidimensional data collection involving loT technologies. Limitations for the ongoing research are presented and future research is foreseen.
