Abstract

When designing new buildings a Double-Skin Facades (DSF) concept is recurrently discussed as an energy saving solution. There is a strong demand for a tool, which could estimate the energy performance of a DSF building in an early design stage, in order to assess whether it fulfills the Energy Performance Building Directive. Therefore, the Bestfacade Project Group has developed the Simple Calculation Method (SCM).

In this paper the calculations of DSF performance using SCM are compared against experimental data gathered in a full-scale model for three data-sets from different periods of the year.

The SCM is recommended for assessing a seasonal DSF performance, however, it gives more reliable results if SCM is applied for shorter periods. Detailed calculation results tend to differ from the measurements, mainly due to overestimating the cooling demand. The validation described in this paper led to conclusions regarding possible improvements of SCM.
