A comparative study of the CFD modeling of a ventilated active façade including phase change materials

Modelling and simulation of Building-Integrated solar thermal systems: Behaviour of the coupled building/system configuration

“…RNG k-ε, Standard k-ω and SST k-ω turbulence models were compared in order to simulate air flow inside the ventilated layer. The authors of [62] noted that the developed model can be considered suitable for the simulation and optimization of the façade under turbulent flow; nevertheless, further research is necessary to improve the accuracy of the model for low-Reynolds-number turbulence conditions.…”

“…A CFD modelling of a ventilated active façade with phase change materials was conducted by Diarce et al [62]. Emphasis was given in the investigation of system behaviour by taking into account the regulations of the Spanish technical building code for the inner layer (brickwork).…”

Solar façades: A review

“…Diarce et al [33] installed a 2-cm-thick PCM panel on the outside of an exterior wall and retained a 6-cm ventilated air gap between the PCM panel and the outer wall. Rabani et al [34] designed an air outlet in the form of a double-skin facade (DSF) where the indoor air was drawn out of the building through the solar chimney effect and a water spraying system was installed at the air inlet to cool the air drawn from the outdoors.…”

Energy efficiency and thermal performance of lightweight steel-framed (LSF) construction: A review

“…Several passive PCM-based TES solutions for buildings have been studied during the last decades, for both opaque and window facades, such as PCM enhanced drywalls [2,[89][90][91][92][93][94][95][96][97][98][99][100][101][102][103][104], SSPCM elements [105][106][107][108][109][110][111][112][113][114][115][116][117][118][119][120], PCM-based ventilated facades [121][122][123][124][125][126], PCM-shutters and PCM-window blinds systems [127][128][129][130][131], interior sun protections with PCMs [132,133], translucent PCM walls [134]…”
