Research on the winter thermal comfort of library's atrium reading space in harbin universities

As a transition space, atrium not only organizes traffic, makes the flow line flexible, but also modulates the indoor micro-climate. Because of its good sense of space and lighting performance, designers generally set reading space around the atrium. But nowadays, people are more concerned with the external form of the architecture, rather than the thermal comfort conditions of the atrium reading space. This article chooses the universities' library atrium space of Harbin in typical city in cold regions as the carrier of research, testes the thermal environment of atrium reading space, analyzes the user's subjective feelings of the thermal environment and establishes climate adaptation model applied to library buildings. This paper aims to study on Winter thermal comfort of universities' library atrium reading space in cold area. Bases on thermal comfort adaptive model, it establishes a reasonable heating methods and design temperature index of indoor thermal environment. Optimum comfort is obtained while achieving building energy efficiency and providing viewers a comfortable reading space.
