Higher GPA scores
Better attention spans and cognitive performance from improved air quality positively impacts GPA scores and outcomes over the long term. Also impacted by reduced teacher and student absence rates.
Better learning environment
Studies and evidence shows that poor air quality especially CO2 dramatically impacts cognitive ability.
Carbon footprint reduction
By saving energy costs Envelo also reduces carbon footprint.
Showing you have a healthy learning environment enhances the reputation and attraction of an organisation.
Annual Energy Savings
On top of increasing air quality, our monitoring technology enables schools to only use energy when you required. This includes heating, ventilation, HVAC, and lighting.
Reduction of Annual Sick-Days per Teacher
Historic data suggests a typical 30% reduction (3-days per year) in staff sickness
According to 2021 data from the U.S. Energy Information Administration (EIA), K-12 schools in America annually spend an average of $0.67 per square foot on electricity and $0.19 per square foot on natural gas.
For example, a typical 1,000 student high school requires around 173,730 square feet to accommodate its students and might pay around $149,500 for energy depending on its location, consumption practices, and ratio of electricity to natural gas usage.
Additionally, 50% of schools in the US have been diagnosed with poor indoor air quality.1 Poor indoor air quality can decrease alertness, productivity and test scores, as well as increase sick leave for both students and teachers. Studies show that classroom CO2 levels of 2500 ppm had much worse test scores than at 1000 ppm.
The NCTQ discovered the average teacher misses 9.4 days of school in year, with sickness being the main reason for absence. With the average daily cost of a supply teacher being $160, teacher absenteeism is a huge financial and administrative burden.
By one estimate, the nation’s school districts spend approximately $4 billion annually to find and hire substitute teachers. On average, teacher absences cost districts an additional $1800 per teacher per year, based on data from a 2017 study.
