“…In this study, Type 2 air caps with 10-mm diameter circular air-filled pockets were used. This choice was based on a previous study, in which the thermal performance of a window was improved using air caps [43]. [42] as a packaging material, comprise a regular pattern of air pockets that are sealed between two sheets of polyethylene film and have been depicted to improve window insulation.…”

“…Air caps, originally developed by the Sealed Air Corporation [42] as a packaging material, comprise a regular pattern of air pockets that are sealed between two sheets of polyethylene film and have been depicted to improve window insulation. In previous studies, air caps were attached to the entire window surface [43][44][45], which may have efficiently improved the insulation performance of the window; however, this may disturb the view through the window and increase the amount of energy required to ensure indoor lighting. Additionally, water or double-sided adhesive tape was used to adhere the air caps [43,44], which caused problems while attaching and detaching the air-caps.…”

While previous research has shown the use of attachable air-caps on windows to efficiently reduce a building’s energy consumption, the air-caps considered had to be attached to the entire window’s surface, thus limiting the occupants’ view and creating the inconvenience of needing to detach and attach the air-caps. In this study, a window-mounted air-cap roller module using Velcro tape that may be easily attached, detached, and rolled up or down was developed and performance tested in a full-scale test bed. It was found that as the area of the air-caps attached on a window increased, the required indoor lighting energy increased. However, the window insulation improved, thus reducing the cooling and heating energy needed. Attaching the air-caps to the entire window surface effectively reduced the building’s energy consumption, but views through the window may be disturbed. Thus, the developed window-mounted air-caps enable an occupant to reduce the building energy consumption and maintain their view according to their need. The findings of this study may contribute to a reduction in building energy consumption without sacrificing a pleasant indoor environment. Further studies may be needed to verify their efficacy under varying indoor and outdoor conditions.

Abstract. Approximately, heat loss from windows utilized as part of building envelopes is 6 times greater than the heat loss that occurs from normal walls. Therefore, it is necessary to constantly improve the performance of windows in terms of comfort and energy saving. Recently, studies regarding the utilization of air caps as a low cost and highly efficient method to improve the heat insulation property of windows are being carried out. As previous studies have been carried out only for fixed and one-time air caps, it is necessary to conduct an investigation regarding detachable air caps according to different functions and conditions pertaining in each season. Therefore, the purpose of this study is to produce a detachable air cap frame and carry out a performance evaluation by comparing electricity consumption between previous double glazed windows and double glazed windows with an internal frame affixed with an air cap.
