The purpose of this study concerns the improvement of air quality in school classrooms. Polluted indoor air is improved by efficient ventilation systems. So it is important to measure the amount of ventilation needed in classrooms. First, the amount of natural ventilation were measured through a tracer gas method. And we have established a heat recovery ventilation system from 4 cases of airflow in classrooms, and we have measured the change of density. According to air quality measurements in the classrooms, the density of is well above environmental standards which are acceptable. When the amount of ventilated airflow increases, indoor air quality is improved. It is surveyed that the most suitable amount of external inducted air is 770 CMH to satisfy less than 1,000 ppm in classrooms. For improvement of air quality in classrooms, we must consider a suitable ventilation plan and installation of ventilation systems when constructing school buildings.

It is increased demands for the efficient heating and cooling system and thermal comfort environment, and deterioration of buildings and facilities can cause education budget to increase lately. So we also urgently need the study related with it. For this reason we selected one university campus in Seoul and then came to understand the current situation and found some problems. Then we selected system air conditioner(EHP) as a suitable heating and cooling system and perform economic analysis of it. And we evaluated propriety of application ESCO project to this. Ultimately we will suggest a reasonable alternative between the improvement of educational environment and increasing energy costs.
