Field measurement of indoor environment of a room with single-sided sliding glass opening

Abstract

The indoor environment of a room is also affected by the opening type and configuration. The application of an opening in a building is mainly influenced by its aesthetic look rather than its environmental performance. Understanding of an opening’s impact towards the indoor environment is essential. The impact of a single-sided sliding glass opening to the indoor environment of a room discussed using field measurement. A room located in a two-storey detached house was selected. Total of ten days from 7 a.m. to 7 p.m., the sliding glass was slid to one side to allow natural ventilation into the room, hence, a cavity was created in between the two glasses. The results of the study indicated that high heat accumulation was detected at the glass surface area which faced the cavity and the air velocity in the room was found to be lower than the outdoor wind speed. This study provides important findings on the performance of a single-sided sliding glass opening and how it impacts the indoor environment of a room then help the building owner, designer, and people in the built environment industry to further understand the performance of sliding glass openings.

Review of Window Performance in A Hot and Humid Climate

“…The most recent field measurement conducted in a residential building demonstrated that sliding windows resulted in low indoor air velocity, high indoor air temperature, and heat accumulation between the window glass (Wellun et al, 2021). This main finding encouraged further investigations of sliding windows, which are still being utilised in residential buildings.…”
