“…The Nano-Enhanced Phase-Change Material (PCM) has significantly contributed to developing energy-efficient constructions. PCM can absorb heat energy and release a large amount of it, making them suitable for energy-efficient use [51]. PCM can improve users' indoor thermal comfort by reducing indoor temperature variations and potentially reducing global energy consumption through power savings [52].…”

Nanotechnology has gradually emerged in various sectors, including architecture. Nanotechnology developed nanomaterials as environmentally friendly and highly efficient construction materials. It behaves differently with enhanced functional properties such as durability, strength, flexibility, lighter weight, self-cleaning capacity, etc. This study investigated the impact of integrating nanotechnology into the construction field from two perspectives: to minimize the environmental impact of buildings based on sustainability principles and to improve the functional efficiency of construction materials. The study aims mainly to propose a strategy for evaluating nanomaterials in construction as sustainable materials through four aspects related to sustainability principles. This was achieved progressively through a methodology that commenced with a theoretical study of the basics of nanotechnology and how it relates to the field of sustainable architecture. Moreover, it described and summarized some prevailing nanomaterials used in construction, such as concrete, glass, coatings, and thermal insulation materials. It also reviewed their functional efficiency in line with sustainability. Furthermore, this study examined some case studies based on the proposed strategy to evaluate the utilized nanomaterials in the case studies. On average, this study's results found that the used nanomaterials in the three case studies achieved 54.3% for sustainable design principles, 83% for Sustainable materials criteria, 60.3% for energy efficiency aspects, and 71.7% for ambient environment efficiency factors. On the other hand, it indicates that using nanomaterials in construction reduces harmful carbon emissions and improves the functionality of building materials to boost sustainable architecture.

“…This means innumerable studies are required to find thermophysical properties for most of the NEPCMs. Moreover, these get harder when it reveals that different loading value or percentage of nano particle is also an effective parameter on the thermophysical properties of developed NEPCM [25]. Therefore, scientists utilized numerical methods to predict the thermophysical properties of NEPCM [7].…”

Thermal characteristics of phase change material (PCM) are important in design and utilization of thermal energy storage or other applications. PCMs have great latent heat but suffer from low thermal conductivity. Then, in recent years, nano particles have been added to PCM to improve their thermophysical properties such as thermal conductivity. Effect of this nano particles on thermophysical properties of PCM has been a question and many experimental and numerical studies have been done to investigate them. Artificial intelligence-based approach can be a good candidate to predict thermophysical properties of nano enhance PCM (NEPCM). Then, in this study an artificial neural network (ANN) has been developed to predict the latent heat of the NEPCM. A comprehensive literature search was conducted to acquire thermal characteristics data from various NEPCM to train and test this artificial neural network model. Twenty different types of Nano particle and paraffin based PCMs were used in ANN development. The most important properties which are used as the input for the developed ANN model are NP size, density of NP, latent heat of PCM, density of PCM, concentration and latent heat of NEPCM in the range of 1-60 nm, 100-8960 kg/m 3 , 89.69-311 kJ/kg, 760 to 1520 kg/m 3 , 0.02-20 wt% and 60.72-338.6 kJ/kg, respectively. The output variable was latent heat of NEPCM. The result indicates that the ANN model can be applied to predict the latent heat of nano enhanced PCM satisfactory. The correlation coefficient of the created model was 0.97. This result shows ability of ANN to predict the latent heat of NEPCM.

“…[10,11] The encapsulation method that forms a core-shell structure has been reported to solve the liquid leakage of solid-liquid PCMs, it used suitable support materials to cover the phase change material by emulsion polymerization, sol-gel technology, suspension polymerization, interfacial polymerization, spray drying, and many more. [12][13][14][15][16][17][18][19][20][21] The shell material is essential for the morphology, mechanical properties, and thermal properties of the preparation MEPCM. [22] Shell materials are roughly divided into organic and inorganic shells according to their chemical properties.…”

A series of paraffin (Pn)@silica (SiO 2 ) microencapsulated phase change materials (MEPCM) were synthesized by sol-gel process using tetraethyl orthosilicate (TEOS) and silane coupling agent as precursors. The morphology and chemical compositions of Pn@SiO 2 microcapsules were characterized by SEM and FT-IR, and thermal energy storage capacity was tested by DSC. The results showed that the Pn@SiO 2 microcapsules modified with 3-methacryloxypropyltrimethoxysilane (MPS) had a desirable phase transition enthalpy (184.12 J/g). Meanwhile, the contact angle and leakage rate of Pn@SiO 2 microcapsules were analyzed, and the data indicated the contact angle of Pn@SiO 2 microcapsules was significantly improved and the leakage rate of Pn@SiO 2 microcapsules was reduced to different degrees by modification with silane coupling agents. The main reason is that the modification of silane coupling agents improves the wettability of silica on the surface of paraffin wax, which makes the aggregation of silica on the surface of paraffin more efficient. Among them, the Pn@SiO 2 microcapsules modified by MPS showed the most significant reduction in leakage rate, which was reduced from 8.38 % to 1.24 %. Pn@SiO 2 microcapsules modified by MPS not only showed outstanding latent heat-storage/release capability with a high capacity but also exhibited good shape stability, high thermal stability and excellent phase-change reliability and durability.
