Children are our most precious assets, and they can be more vulnerable to many environmental contaminants than adults. Children’s bodies are still developing, and they may be exposed to more environmental contaminants than adults because they eat, drink, and breathe more per pound of body weight, and because their behaviors – like putting things in their mouths and playing on and close to the floor– may bring them in greater contact with contaminants than typical adult behaviors.
Providing educational facilities that nurture the learning process is a fundamental societal responsibility that goes hand in hand with the goal of ensuring that every child receives a high quality education.
- In the United States, more than 53 million elementary and secondary students attend approximately 119,000 public and private schools.
- The average child spends about 1,300 hours in a school building each year; teachers and other employees spend even longer periods.
- Today, the average school building is about 42 years old.
- More than 75% of America’s schools were built before 1970.
Unfortunately, in far too many cases, because of severe past budget shortfalls, many of our schools are in poor condition, leading to a host of environmental problems that can have dramatic impacts on children, staff, learning, and the fiscal bottom line. The General Accounting Office, and the National Center for Education Statistics of the Department of Education, among others, have documented the poor physical condition of many of our older school facilities.
- Studies show that student achievement is related to the quality of the school environment and indoor air quality issues consistently rank among the top environmental risks to public health.
- In 1999, one in five schools in the United States reported unsatisfactory indoor air quality (IAQ); one in four had inadequate ventilation. Good indoor air quality is an important component of a healthy indoor environment, and can help schools reach their primary goal of educating children.
Indoor air problems can be subtle, and do not always produce easily
recognized impacts on health, well-being, or the physical plant. Nevertheless, failure to
prevent and respond promptly and effectively to IAQ problems that do arise can
have serious health, cost, and educational consequences:
- Increasing long- and short-term health problems such as cough, eye irritation, headache, asthma episodes, and allergic reactions, and, in rarer cases, life- threatening conditions such as severe asthma attacks, Legionnaire's disease or carbon monoxide poisoning;
- Promoting the spread of airborne infectious diseases;
- Aggravating asthma and other respiratory illnesses. Nearly one school-aged child in 13 has asthma, the leading cause of school absenteeism due to chronic disease. There is substantial evidence that indoor environmental exposure to allergens, such as dust mites, other pests, pet allergens, and molds play a role in triggering asthma symptoms. These allergens are found in the school indoor environment;
- Producing an unfavorable learning environment for children;
- Reducing productivity of teachers and staff due to discomfort, sickness, or absenteeism;
- Accelerating the deterioration and reducing the efficiency of the school's physical plant and equipment;
- Increasing the risk that school rooms or buildings will have to be closed, and occupants temporarily relocated;
- Straining relationships among the school administration, parents, and staff;
- Generating negative publicity that could damage a school's or administration's image and effectiveness; and,
- Creating potential liability problems.
While indoor air quality is a critically important aspect of creating and maintaining school facilities, many jurisdictions and organizations are embracing the concept of designing "High Performance Schools" that is based on an integrated "whole building" approach to address a myriad of important – and sometimes competing – priorities such as energy efficiency, indoor air quality, day-lighting, materials efficiency, and safety, all within the context of tight budgets and limited staff.
