A nomogram is presented for use in regions with a Mediterranean climate. Architects can use this tool as an easy way to optimize the design of shading devices. The nomogram allows the performance of a proposed external fixed shading device to be evaluated. The input variables required are (i) the location of the building, (ii) the orientation of the facade and (iii) two adimensional characteristics corresponding to the opening-shading device system. The accuracy reaches its minimum value during intermediate seasons but the margin of error is less than 10%.
