JAUE2017-076: The Comparison of Composite Trombe Wall Systems with Single Glass, Double Glass

Abstract

In this paper, the temperature performance comparison of single glass and double glass integrated on the 
composite Trombe wall façade of a model test room built in Kitakyushu, Fukuoka, Japan has been carried out. The 
system has been operated during winter months. The composite Trombe wall is oriented on the south side of the 
building. The building satisfies the Japan thermal regulation. The central concrete core of the wall is covered with 
a layer of dark paint, to improve absorptivity of the wall. The passive heating potential of composite Trombe wall 
was estimated using the dynamic thermal load calculation software, THERB. The temperature of the air layer of 
composite Trombe wall are simulated. This model will be used for optimization of the system in different climatic 
regions, locations and for different building typologies. This project aims to be a prototype and to become 
widespread throughout Japan and the world as it is easy both to renovate existing buildings with these systems and 
to apply them to new ones.
