Recently, our society is becoming increasingly enthusiastic to acquire knowledge and quality education. Thus, private houses, schools, public libraries and even subways are becoming places to acquire knowledge. Out of all these places, the library, where people visit most frequently to study, has to be quiet, effective and pleasant in order to provide the most efficient place for maximizing learning performance. Many people use public libraries and the age group of people who visit public libraries are very diverse, which makes it particularly necessary to provide the conditions mentioned above. The purpose of this paper is to measure and analyze the differences of thermal comfort and soundscape of library N, which is located in the quiet woods, and library G, which is located in the city center. The measurement and analysis results will be used to evaluate which library has a more pleasant environment.
