Fig. 2. Overview of dimensions of case E2 (dimensions in m). (a) Front view (upwind facade) with opening size and dimensions. (b) Vertical cross-section with opening size and
dimensions. (c) Perspective view. The other roof geometries (A,B) have the same roof height, facade porosity (inlet-outlet opening size), building depth (D) and width (W); however,
they have different roof geometries and consequently different internal volumes.
