On the thermal behaviour of roof-mounted radiant barriers under tropical and humid climatic conditions: modelling and empirical validation

Thermal Performance of Photovoltaic Systems Integrated in Buildings

“…In our case, they have been totally developed and dedicated to the present study and constitute an original contribution to international studies about complex walls, especially including PV systems. Many publications have involved these tools, for example (Miranville, 2003) and (Bigot, 2009). The numerical code used to predict the thermal response of the whole building envelope is part of the thermo-hygro-aeraulic simulation codes and is based on a multizone description of the physical system (here composed of the building and its very specific wall with PV).…”

“…The goal is to find the energy transfer across the solar system and its coupling with the building, it is not necessary to model finely phenomena. In addition, the coupling of the wall model with the PV will be done with an existing code, named ISOLAB (Miranville, 2003). This code models each type of walls in the same manner, by reducing the thermal problem at the scale of the material layer.…”

Enhancement of natural ventilation of a novel roof solar chimney with perforated absorber plate for building energy conservation

“…Numerous investigations on the effect of the parameter of roof solar chimney have been carried out because the design and the parameter of a roof solar chimney are critical for the fluid flow and heat transfer in roof solar chimney [6][7][8][9][10][11][12][13] .Other studies have focused on the optimization of roof solar chimney and the studies of roof solar chimney combined other technologies [14][15][16][17][18][19][20][21][22][23][24][25][26].…”

“…Miranville et al [16] performed the modelling and empirical validation of a building thermal model consisting of a roof-mounted radiant barriers under tropical and humid climatic conditions. They also found that convective heat transfer is of great importance for the dry-air temperature of the roof air layer.…”

Impact of Heat Reflective Coatings on Heat Flows Through the Ventilated Roof With Steel Coatings

“…The temperatures of the ventilated air gap and its boundary surfaces are greatly influenced by the temperature of the steel roof coating which rapidly reacts to the impacts of the exterior air temperature and solar radiation since it has a low thermal receptivity. The steel roof coating heats up under the effect of short-wave solar radiation (Miranville et al 2003;Cheikh, Bouchair 2004;Šeduikytė, Paukštys 2008;Stephenson 2009;Banionis et al 2011) and due to the convective heat transfers, it also heats the exterior air, passing into the ventilated air gap. Thus, the temperature of the air becomes much higher than the temperature of the exterior air.…”
