Review and Mapping of Parameters for the Early Stage Design of Adaptive Building Technologies through Life Cycle Assessment Tools

“…Similarly, Kinetic systems are also focused on an application in building envelopes [41,42]. Few available studies on specific adaptive technologies were also included, as PCM integrating technologies [52,53] and a shape-change technology [54]. Autoreactive systems appeared to be still a minority, although their development and use have been theorised both in terms of kinetics [5] and material technology [6,55].…”

“…Potential benefits from the application of tPCM as LHS units in buildings vary consistently with the geographical location and the thickness of the PCM elements [92,93]. Further questions regarding the sustainability of tPCMs are raised following the need to encapsulate the materials, and more specifically regarding eventual leakage issues and recycling issues in the end of life phase [48,52,53,67,94]. Parameters that are not known concerning the use of paraffins in architecture concern their efficiency and operation over long timeframes [40].…”

Phase change material thermal energy storage systems for cooling applications in buildings: A review

“…The world population and economy are growing rapidly that has led to massive increase in the world's energy demand and consumption, thereby playing a huge role in triggering severe environmental impacts [1]- [8]. According to the data published by Eurostat, European Union member states have seen a remarkable increase in their final energy demand that reached approximately 1084 million tons of oil equivalent (Mtoe) in 2015, of which 422 Mtoe corresponded to building-related sectors that is equivalent to 39% of the total demand [9]. The building sector, being the largest energy-consuming sector, accounts for over 33.33% of final energy consumption on a global basis and is considered an equally important source of CO 2 emission [10].…”

“…Developing a novel technology to promote energy efficiency and conservation in buildings has been a major issue among governments and societies whose aim is to reduce energy consumption without affecting thermal comfort under varying weather conditions [14]. The integration of thermal energy storage (TES) technologies in buildings contribute toward the reduction of peak loads, uncoupling of energy demand from its availability, allowing the integration of renewable energy sources, and providing efficient management of thermal energy, thus leading to the improvement of energy efficiency in buildings [9]. Latent heat TES using phase change materials (PCMs) have gained extensive attention in building applications owing to their high energy storage density capabilities and their ability to store thermal energy in a constant temperature phase transition process [15].…”

Experimental Research on Using Form-stable PCM-Integrated Cementitious Composite for Reducing Overheating in Buildings

“…The incorporation of PCM into building elements to enhance building energy efficiency has been extensively studied using experimental, analytical and numerical approaches. PCM-incorporated building components such as wallboards [10,11], tiles [12,13], bricks [14], cement mortars and concrete [15][16][17][18] were widely investigated as they offer large heat transfer surface areas within the building, enabling a high heat transfer rate. Among these technologies, PCM-integrated cement mortars applied as interior plastering mortars can be considered as a versatile method owing to their inherent merits of the high heat exchange surface to depth ratio; a large amount of PCM can be accommodated as they are non-structural elements and they can be used in existing buildings as an energy refurbishment approach.…”
