Selection of glazing material for Trombe wall applications in Johannesburg using the TOPSIS methodology

Glazing are functional components of Trombe walls, they determine to a great extent the performance of the system. selection of optimal glazing for trombe wall application was considered in this article and the TOPSIS methodology was employed. TOPSIS is a multi-criteria decision-making algorithm which means a technique for order preference by similarity to ideal solution. considered in this article were four different glazing types and four criteria. the single glazing was the closest to the ideal solution followed by the double pane glazing with low emissivity coating, double pane glazing with high emissivity coating and the triple pane glazing respectively.
