School Ventilation Provides Healthy Environment For Students

Ventilation is the process that is used to remove any unpleasant smell and excessive moisture inside a room by introducing outside air

. No building can be build without the presence of ventilation. Poor ventilations usually make irritation in body as well s causes head ache and discomfortableness. Only these can prevent the stagnation of interior air. It also maintains indoor quality of the building Ventilating can be of two methods like forced or mechanical and natural. Ventilation dilutes odours as well as limits carbon dioxide.

School are the building where thousands of kids come daily. Children are susceptible to poor indoor air quality. Pollutants get increases due to greater volume of air. This may result in airborne diseases and tends to spread bacteria and viruses exposing the students to toxic allergens.

The government of UK has passed rule that it"s compulsory the schools must be designed with proper school ventilation system. So it"s the necessary for the management to do the necessities to make students comfortable. One such basic need is classroom ventilations. The type of tool used is named as class vent and class cool. Class vent is used to select strategy and size while class cool predicts the degree of temperature in summer.

The school ventilation system not only minimise the carbon emissions but also there are several other advantages like the ventilation provides enough day light to the class room. Sun pipes are used widely in schools in providing natural lights alternative to roof light and sky light. The natural light projects a soothing and calming atmosphere to the students. This heavily eliminates the use of electricity. Also the noise produced in the class rooms are controlled to certain extent. Thus this ensures good health and thermal support.

The type used in school ventilation system is usually natural ventilation. It is achieved by open able windows or trickle vents. Some of the main advantage of natural ventilation are they provide high quality of indoor air, they help in saving energy, they control occupant illness and finally helps in increased productivity.

Sometimes local exhaust ventilations are preferred in avoiding the contamination of indoor air by high emission sources by capturing air pollutants before they get contaminated. This may be water vapour control, bio effluent control or even small dust particles from metal working industries. The exhaust fans are made of five important parts namely hood, ducts, air cleaning device, and a fan and finally exhaust stack.

Ventilation reduces the indoor pollutants and provides enough quantity of outdoor air. Proper school ventilation system reduces the risk of absenteeism, enhanced teacher output as well as students learning capacity. Advantages of school ventilation system are:

"Good ventilation provides healthy surrounding to the students

"Ventilation provides daylight thus eliminating the use of electric light

"Ventilation supports good health avoiding the sensation of head ache, irritation, tiredness etc.

"Ventilations decrease the noise level produced in the class room.

"Ventilation most of all provides soothing and calm atmosphere.

"Ventilation reduces the pollutants affecting the health of students.
