How indoor environmental quality affects occupants’ cognitive functions: A systematic review

Cognitive functions refer to the set of brain-based skills execute tasks various difficulty levels. As people spend substantial time indoors, indoor environmental quality (IEQ) influences occupants’ cognitive and consequently their learning work performance. Previous studies have commonly examined effects IEQ on integrated or performance, rather than specific skills. The present review decomposes into five factors—indoor air quality, thermal environment, lighting, noise, non-light visual factors. It divided cognition categories—attention, perception, memory, language function, higher order skills—to better understand relationship between cognition. We conducted a detailed manual 66 focused adopted co-occurrence analysis generate landscapes associations factors by analyzing keywords abstracts 8133 studies. Overall, results show that poor conditions are but not always associated with reduced However, factor different quite distinct. Likewise, function could be affected varying degrees. Furthermore, suggest extensive inconsistencies in relevant literature, especially regarding IAQ environment Additionally, keyword identified more emerging recent literature. Future recommended explore causing we highlight here.
