Louvre Windows in Schools Can Improve Your Child’s Learning!

We all want the best for our children. We want them to do well in their studies, remain in good health, be friendly and have good manners.

While I haven’t seen any scientific studies recently about how to improve their manners or be more friendly, there are many scientific studies showing that it is possible to improve their performance at school and reduce the frequency that they get sick by simply opening up windows to let in more fresh air.


Studies Showing Improved Learning Outcomes

A study in 2006 showed that children in classrooms with higher outdoor air ventilation rates tend to achieve higher scores on standardised tests in math and reading than children in poorly ventilated classrooms.1

Controlled studies published in 1999 and 2000 showed that children perform school work with greater speed as ventilation rates increase. The performance of adults, including teachers and school staff, were also shown to improve with higher ventilation rates.2

A 2005 study of 10-year-old school children showed that increasing ventilation rates could improve the children’s performance in tasks representing eight different aspects of schoolwork, from reading to mathematics.3

A study in eight English primary schools of over 200 pupils showed significantly faster and more accurate standardised test responses (by up to 15%) when classrooms had high ventilation rates compared with low ventilation conditions.4

An international review found that green schools and universities deliver up to 15% improvements in student learning and productivity, and up to 25% improvements on test scores from good lighting and ventilation.5


Studies Showing Improved Health

A German study of multiple buildings identified a 33% reduction in reported headaches and a 28% reduction in reported frequency of head colds in naturally ventilated office buildings as compared to air conditioned office buildings.6

In a study in a hot and humid climate, researchers found that students attending naturally-ventilated child care centres had lower levels of asthma symptoms and allergies than those in air-conditioned child care centres.7

A case study of office workers moved from a building with sealed windows and mechanical ventilation to a building with operable windows and natural ventilation identified a 71% reduction in absenteeism.8

A study across 434 classrooms from 22 schools showing that carbon dioxide levels (an indicator of ventilation rates) 1,000 parts per million above the outdoor concentrations of carbon dioxide was associated with 10 to 20 percent increases in student absences.9

Maximise These Benefits with Altair Louvre Windows

Unlike most other window types, Altair Louvre Windows deliver ventilation through the entire window area, so they maximise the rate at which fresh, outside air can be allowed into your child’s classroom. This high ventilation rate is also part of the reason why they’re incredibly energy efficient. Read more about the ventilation and energy efficiency of Altair Louvre Windows here.


Built Tough

With all the busyness and activity in schools it’s important to know that Altair Louvre Windows are constructed entirely from non-corrosive materials like aluminium, stainless steel and industrial strength plastics. An optional feature that is popular in schools is the Stronghold System which uses an acetal plastic pin to mechanically fix the blades into the clips. Altair Louvre Windows with the Stronghold System can resist far higher forces than regular louvre windows and tools are required to remove the louvre blades. Read more about the Stronghold System, including information on fall prevention here.
