Modelling of surface and inner wall temperatures in the analysis of courtyard thermal performances in Mediterranean climates

Courtyards are an effective passive strategy for improving the energy performance of buildings. However, there is a lack accurate simulation tools their thermal due to complex thermodynamics. This paper’s contribution coupling CFD model with system differential equations at walls, governing surface and inner wall temperatures, providing computation courtyard performance. On this basis, boundary conditions standard Boussinesq wind velocity, pressure within established. Modelling results compared monitored data in two days different months Seville (Spain). Simultaneously, simulations carried out by existing software were performed. Resulting showed more accuracy than tools, Root Mean Square Error 1.19 (August) 1.59 (October), while corresponding values ENVI-met 3.31-3.4, Ladybug Tools 2.59-4.49.
