“…Passive building systems use the incorporation of PCMs into building components such as floors [15], walls [16][17][18][19][20], roofs and ceilings [21][22][23][24][25][26][27], transparent elements [28][29][30], and shading solution [31]. The integration of PCM changes the thermal-storage properties of the building structures.…”

“…For this reason, many researchers have studied radiant solutions as a conditioning system since they can be considered among the technologies capable of meeting the requirements of sustainable heating and cooling [28]. Recently there has even been a boom of publications on experimental characterisation for the correct operation of this type of solution inside buildings [29][30][31], none of them applied in open spaces.…”

The global need for healthy and safe open spaces faces continuous temperature rise due to the heat island phenomenon and climate change. This problem requires new strategies for improving the habitability of open spaces (indoor and outdoor conditions in buildings). These techniques include reducing solar radiation, reducing the temperature of surrounding surfaces, and reducing the air temperature. The radiant solutions are essential for outdoor comfort, both in summer and in winter. They are easy to integrate into open spaces. This study explores a new concept of radiant solutions adapted for outdoor spaces. The solution was evaluated in a test cell to obtain its thermal behaviour in different operation conditions. Solutions were optimised for operating in a cooling regimen since it has been identified that the demands for comfort in open spaces in hot climates during the most severe summer months are more pronounced. Experimental results have allowed getting an inverse model to analyse the thermal behaviour of the solution. The inverse model achieved high precision in its estimations. Also, it facilitated knowing the radiant and convective effects. Only the radiant heat flux is relevant in open spaces with a low level of air confinement. Finally, the discussion describes the application of the proposed model. The model allows the replicability of the solution—creating new designs (integration) or evaluating into different operating conditions of the system. This discussion demonstrates the high level of knowledge acquired in the characterisation of the solution studied.

“…Results indicated that using PCM in the roof structure decreased the indoor heat flux and interior wall temperature was closer to the indoor air temperature. Bogatu et al [16] investigated the performance of novel macroencapsulated PCM as a ceiling cooling component compared to commercially available radiant cooling technologies. The installed heat storage capacity was enough to shift the cooling demand to off-peak periods when the PCM was fully discharged.…”
