The indoor built environment plays a crucial role in our well-being, both due to the amount of time we spend indoors and the ability of buildings to positively or negatively influence our health.
A recent U.S. study of 24 participants spent 6 full work days (9 a.m. – 5 p.m.) in an environmentally controlled office space, where they were exposed to IEQ conditions representative of both Conventional (high volatile organic compound (VOC) concentration) and Green (low VOC concentration) office buildings.
Additional conditions simulated a Green building with a high outdoor air ventilation rate (labeled Green+) and artificially elevated carbon dioxide (CO2) levels independent of ventilation.
The study found that, on average, cognitive scores were 61% higher on the Green building day and 101% higher on the two Green+ building days than on the Conventional building day (p<0.0001). VOCs and CO2 were independently associated with cognitive scores.*
This study shows cognitive function scores were significantly better in Green+ building conditions compared to the Conventional building conditions for nine functional domains.
By ensuring that your building has a properly designed and installed HVAC system, you can mitigate the risk of poor indoor air quality, and create optimal conditions for health and productivity.
Outside air rates should be designed as per ASHRAE 62, the code for ventilation for acceptable indoor air quality.
