Abstract

In modern and contemporary architecture, glass is actively used as a building material with various characteristics such as transparency, lightness, and creation of a modern image. On the other hand, glass is a very weak building material in terms of energy; therefore improvement measures such as double and triple-insulating glass and low-emissivity glass have been proposed. However, most proposals have only focused only on sensible heat, and discussions related to latent heat have been insufficient. Because glass has relatively very low moisture adsorption and desorption performance compared to other building materials, it may be disadvantageous in terms of latent heat load and humidity control. In this study, a simple experiment was conducted using wood, glass, and low-e glass test bodies to identify the tendency of indoor humidity fluctuation due to the building envelope with low moisture adsorption and desorption performance. As a result of this experiment, in the case of a space surrounded by glass, it was confirmed that the indoor humidity rapidly fluctuated according to the humidity of the outside air due to the low moisture adsorption and desorption performance of the envelope.
