AB Sustainable passive design strategies can reduce the energy consumption of buildings. In this regard, innercourtyards act as microclimate modifiers that enhance the perception of comfort in the surrounding environment.The present study, through a pooled analysis of experimental and numerical data, intends to assess thebeneficial effect that the courtyards have in reducing the energy consumption of the buildings, especially forcooling demand. Accordingly, a new methodology allowing the use of different experimental data for facades andcourtyards in software tools for the assessment of the real energy performance of buildings with courtyards isproposed. Besides, a detailed example of the application of the proposed methodology is performed for twoscenarios simultaneously: a case study (considering the courtyard effect on the air temperature) and a referenceone (without considering this effect). From the results, it is found that the courtyard reduces the demand forcooling in the spaces bordering it. As expected, the magnitude of the cooling demand reduction is correlated tothe floor level, is increased at lower floors in the courtyard building. This relative reduction is up to 11%, being,for the case study analyzed, an average reduction of 7%.
