摘要：

A double ventilated window is formed by two parallel windows in the same facade opening with a ventilated air-channel between them. Under inward flow conditions and incident solar radiation this works as a solar collector. The solar radiation absorbed by the outer and inner windows heats up the passing air in the air channel before it is delivered inside. Still, part of the solar radiation reaches directly the indoor environment through the glazed part. This paper is a presentation of an experimental and analytical study of the solar heat gain coefficient (SHGC) of a ventilated double window under different working conditions and for several types of glasses and different glass to frame ratios. The variation of SHGC values with each influent factor is provided which can be useful for a dynamic whole building energy analysis. (C) 2014 Elsevier B.V. All rights reserved.
