CO2 Monitors for private preparatory schools

Carbon dioxide is a gas included in the atmosphere, which does not have venomousness and harmless itself. Not like temperature, we do not feel carbon dioxide consistency daily and because CO2 monitor was not inexpensive, we had limited opportunities to know carbon dioxide consistency.
However, it is an accepted notion that high carbon dioxide consistency causes decline in thinking power and higher carbon dioxide consistency causes harm to the human body is substantiated.

Therefore, we would like to make a suggestion of CO2 monitors’ installation to private preparatory schools’ directors and teachers.

【Advantages of CO2Monitor installation】
１．Care for students and teachers’ health
　　CO2 Monitors will help to comply and optimize the school environmental hygiene standard for the classrooms and building.

２．Contribution for the improvement of the learning efficiency
　　CO2 Monitors will help to prevent of sleepiness in the classroom and improve learning efficiency.

３．Utilize for energy saving
　　CO2 Monitors will help to save air conditioning, ventilation electricity by minding appropriate ventilation.

【Carbon dioxide consistency and relations of uncomfortable feeling and the health damage】
・More than 1000PPM　　Air-sensitive people would think “Poor air”
・Around 2000PPM　　Increase drowsy people.br />
・More than 3000PPM 　 If you stay for long, adverse health effects expected.
・More than 5000PPM　　If you stay more than 8 hours, it poses a health risk.　

【Laws and regulations on the carbon dioxide】
・The standard of the school environmental hygiene（Ministry of Education, Culture, Sports, Science and Technology）
　As a standard of the ventilation, it is desirable for the room to be equal to or less than 1,500ppm (0.15%)

・A standard of the building Management Act－Less than 1,000ppm（Specific buildings more than floor space 3,000 square meters）
