PCM WALL SYSTEM ALTERNATIVES PROVIDING SIMILAR THERMAL CONDITIONS WITH TRADITIONAL BUILDING ENVELOPE IN HOT-DRY CLIMATE

Merve Kılınç, Neslihan Türkmenoğlu

Abstract: Traditional settlements and buildings are great examples of architecture of a region with their original construction technics produced for adaptation to climate and topographic conditions as it is in dry climates with buildings with massive walls, the main architectural identity elements of this climate type. Massive walls store sensible heat, provide stable interior air temperatures and delay the peak temperature in the daytime. Furthermore, phase change materials that store the thermal energy in the environment as latent heat during solid-liquid, liquid-gas, solid-gas, and solid-solid phase changes and release the stored latent heat to the interior during reverse phase change can be used in dry climates constructed with thinner walls instead of old massive walls in newly built areas. PCM materials with thin layers can reduce heating, cooling loads and minimize interior temperature fluctuation as massive walls that can store sensible heat. Within the scope of this study, wall alternatives with PCM material that offer similar performance to the internal operative temperatures provided by the building envelope with 90 cm typical thickness of outer walls of traditional buildings assumed to create ideal climatic conditions in Mardin, Turkey having hotdry climate conditions are investigated for summer and winter conditions. Operative temperatures and cooling loads are obtained by simulation process conducted by Designbuilder energy analysis program.
