Abstract
This paper examines a method for calculating the thermal performance of curtain walling with frames. A general calculation method was used for obtaining thermal insulation and sun shading performances of curtain walling by referring to ISO and existing investigation. As there have been no fixed calculation methods and the range of modeling frames has not been clearly defined so far, it was not possible to identify thermal performance of curtain walling. Due to this, it has been often the case that the thermal performance of it is calculated assuming that curtain walling is a simple wall consisting of opening units as glazing and spandrel panels as panel materials. As a result of calculating thermal insulation and sun shading performances, the degree of affecting frames, glazing and spandrel panels to them has been made clear. Especially, the necessity for considering the frame in evaluating the thermal insulation performance became clear.
