Performance Review of C18 Paraffin Phase Changing Building Materials in Different Climate Zones

Environmental conditions impact the performance of building materials; therefore, material used can be considered one major factors that directly affect building's lifespan. The need for durable materials to mitigate effect environmental on buildings has been a research point, which led development phasechanging materials. PCM are designed adapt and harness elements, such as heat cold, typically harm building, make even more efficient. C18 paraffin is shape-stabilized phase change most widely applied in envelopes worldwide. This study reports paraffin-based material; this across globe. assessment carried out four distinct climatic zones defined by ASHRAE 169-2013 zone guidelines. evaluation reported based energy requirements three different diameters PCM, 5cm, 10cm, 15cm. paper varying degrees use heating cooling needs buildings, however despite difference performances zones, studies still report findings show efficiency compared conventional all heating.
