And its effect on learning environments
Exposure to excessive indoor carbon dioxide will impair learning, engagement and performance. The damaging levels are surprisingly low. The Learnometer sensor can detect levels between 400-5,000ppm ±75ppm or 10%.
Professor Heppell indicates that above as little as 1,000 parts per million CO2 will be inducing sleepiness, poor concentration with abnormal heart rate and nausea. Problems increase towards 5,000 ppm which many learning spaces often exceed daily. Our recommendation is no higher than 2,200 ppm
