The heating effect of the additional solar house to classroom in the cold region---A case study of an elementary school

Abstract

It is important to develop solar energy resource potential for improving indoor thermal comfort. In this paper, we used the statistical method to analyze observation data for temperature change in an elementary school classroom located in the clod region. The temperature data are recorded hourly in outdoor, the sunspace attached (SA), the classroom with a SA, and the reference classroom (RC) respectively. Results show that the daily mean temperature of the classroom with a sunspace attached (CAS) is higher 6.6°C than RC in the heating period. The heating effect of the sunspace is obvious during the day, while a lot of heat loses at night. To reach the indoor suitable temperature of 16°C, the fuel 315.51kgce are required, and only 61.1% of the heating requirement of the classroom are met. In order to increase the heat effect of SA, it is essential to improve the structure of the sunspace and building material properties.
