Integration of LEED indoor environmental quality credits into BIM software to design educational buildings with enhanced quality of indoor environment

Introduction & Background
According to the studies of U.S. Environmental Protection Agency (EPA) the level of pollutants inside the building can be two to five times higher than the outdoor levels and these pollutants are major cause of worry as majority of people invest their 90 percent of time in indoor activities (10). The educational buildings are heavily occupied most of the time as they provide facilities like classrooms, libraries, laboratories, etc. Hence, it is imperative to maintain indoor air quality of important buildings like educational buildings considering they have such a large amount of occupants.
The problems of indoor air quality in schools could be more serious than in other categories of buildings, due to a higher occupant density and insufficient outside air supply (also ventilation), worsened by often poor construction of school buildings (1). Generally a student is involved in a classroom for about 1300 hours in one year and hence poor indoor environment of an educational building can have a negative effect on a student (3).
LEED (Leadership in Energy and Environmental Design) is being largely incorporated into sustainable design and construction within the United States of America and in the various categories of LEED there is one category which addresses to the problem of indoor air quality. The
