A "healthy and high performance school" uses a holistic design process to promote the health and comfort of children and school employees, as well as conserve resources. Children may spend over eight hours a day at school with little, if any, legal protection from environmental hazards. Schools are generally not well-maintained; asthma is a leading occupational disease of teachers and custodians--"that is, they get it on the job". There is a strong basis in science for designing schools: 1) for healthy indoor environments, and 2) for resource conservation. Together, healthy + green designed facilities promote indoor air and environmental quality; thermal, visual, and acoustical comfort; and, energy, water, and material conservation. Such facilities can also minimize construction/maintenance waste, fumes, debris and particulates that can harm school occupants and harm the environment. Design out common schoolhouse problems: "healthy + green = A+". This paper provides tips for designing healthy and high-performance schools.
