90% of schools are OVER or UNDER ventilated.
Which side of the line does your school fall?
Yay! Your teachers and students have a great environment to do what they do best. Unfortunately that sweet breeze comes at a price.
⁃ HVAC is your largest utility expense and chances are, up to 50% of that literally went out the window.
⁃ Too much outside air means your HVAC system is oversized with more electrical service than necessary.
⁃ Excessive outside air can create excessive moisture problems. Is your dehumidification system up for the challenge?
You have saved some serious dough, but at what cost?
⁃ Students in well-ventilated classrooms perform significantly better on standardized tests than their peers who received inadequate fresh air. (University of Tulsa's indoor air program http://www.healthyfacilitiesinstitu…rformance)
⁃ Contaminants already present in classrooms such as molds, viruses, odors, cleaning chemicals, art supplies, adhesives, paints textiles and chemicals may contribute to more sick days and absenteeism.
⁃ You may be held liable for real or perceived risks that exist in the child's learning environment.
Fact: 15% of schools w/ ventilation systems inhibit or unplug it's operation altogether.
Fact: ASHRAE 62. 1-2007 - and International code IMC 2009 require 10 CFM per student + Classroom Sq/Ft x 0.12
Example, if you had 25 students in a 900 sq/ft classroom it would look like this:
25 people X 10 CFM = 250 CFM (CFM = Cubit Feet per Minute)
900 Sq/Ft X 0.12 = 108 CFM
250 + 108 = 358 CFM for that classroom.
Ventilation requirements have changed 3 times in the last 25 years and are likely to change again in the future. Can your ventilation system adapt?
