“…Oxidation of paraffin wax from these boards was observed at 210 C to 250 C 32 and this agrees well with the exothermic oxidation reaction observed at 233 C of PCM microcapsules heated at 5 C/min. 33 Evaporation of paraffin wax was observed from 227 C to 347 C and the shell melted during 280 C to 450 C as reported in Reference 29.…”

Lightweight cold-formed steel (CFS) construction solutions are increasingly adopted in low and mid-rise buildings. Many different materials are used to construct CFS wall systems, without a full understanding of their thermal properties. For many of these materials, only ambient temperature thermal properties are available from their manufacturers. This creates difficulty in classifying the materials for use at elevated temperatures. In this study, a series of elevated temperature thermal property tests to measure specific heat, thermal conductivity, and mass loss was conducted for a range building materials from wallboards, insulation, and phase-change materials (PCMs), used in Australia and several other countries. Simultaneous Thermal Analyser and Laser Flash Apparatus were used to determine the elevated temperature thermal properties of the selected materials, gypsum plasterboard, PCM incorporated gypsum plasterboard, magnesium sulphate board, fibre cement board, cellulose insulation, vacuum insulation panel, microencapsulated paraffin PCM, and bio-based PCM. Their elevated temperature thermal properties are presented in this article, which also includes analyses of their chemical composition and associated chemical reactions at elevated temperatures. These results can be used in the selection of suitable energyefficient and fire-resistive materials, and in heat transfer modeling to identify wall configurations with increased fire resistance and energy efficiency.

“…The obtained results from the test indicated that there is no ignition in the reference PB, producing negligible THR of 0.7 MJ/m 2 with mass loss of 18.9%. This is attributed to release of water molecules in the crystal lattice of PB in the form of water vapor at high temperatures due to the dehydration reactions, contributing to improve the fire resistance of wall as a result of the reduction in wall temperature 53,66 . As shown in Figure 10A and Table 4, all samples containing ISOP burned with two peaks of heat release rate.…”

“…On the other hand, the flammability of organic PCM is considered the prime significant threat for use in buildings. The flammability of PCMs is emerging in the literature 11,53,54 . In case of a fire, significant amounts of smoke, flame, and toxic gases 55,56 can be produced as a result of the burning of PCMs, which can be transferred simply through the building, causing deaths, injures, and property losses 57,58 …”

Summary In recent years, the latent heat thermal energy storage using phase change materials (PCMs) has become a hot topic; it has attracted much attention in the utilization of renewable energy sources to improve the energy efficiency of buildings. Isopropyl palmitate (ISOP) with phase transition temperature of 10°C to 13°C and heat of fusion of ~113 J/g was selected to be used as a PCM in building applications. ISOP, 15%, was mixed with plasterboard (PB) as a building material in two techniques, immersion and direct incorporation, in order to retain the ISOP into the porous structure of PB. Scanning electron microscope (SEM) demonstrated that the layer structure of the PB particles was uniformly absorbed by ISOP. Phase transition temperature of ISOP in both techniques determined using differential scanning calorimeter (DSC) is still similar to that of ISOP accompanied with much reduction in the latent heat, particularly in the direct incorporation technique. TCA 300 thermal conductivity analyzer addressed that the thermal conductivity of the PB has been slightly increased with the addition of ISOP. The stored thermal energy performance in a small test room is experimentally investigated. These results indicated that applying ISOP to the south wall of the testing room had the potential to reduce the fluctuation of the indoor air temperature. The effect of ISOP on the mechanical properties of PB has been investigated in the flexural mode using three‐point bending test. Moreover, the fire risk of ISOP has been assessed using cone calorimetric. The results confirmed that the novel composite ISOP has a significant opportunity in building applications for thermal energy storage.

“…In the daytime, PCMs melt by absorbing energy from the surrounding environment and then re-solidify at night, releasing the stored energy. This process reduces the need for cooling in the daytime and heating at night [56,57].…”

Review on Energy and Fire Performance of Water Wall Systems as a Green Building Façade

Glass façades are widely utilized in green buildings. Ensuring fire safety while reducing the energy need without compromising occupants’ comfort is a challenge in the modern-day green buildings with glass façades. One way of achieving both aspects is to construct a water wall system as a building façade. A water wall system has a water layer between two glass panes and can be considered as a glass façade system. The focus of this review, which builds on the published studies, is how water wall systems can help ensure fire safety and reduce energy demand in green buildings. The water layer within two glass panes of the water wall system store the solar radiation heat throughout the daytime, reducing the amount of heat transferred through the building facade. The reduced heat transfer effects lessen the need for air conditioning to sustain the thermal comfort of the building occupants. The stored energy is released during the nighttime. The transparency of the water wall system also allows daylight to enter the building, thus reducing artificial lighting needs. Furthermore, the water layer acts as a fire safety mechanism in case of a fire. However, the water wall systems are not much utilized in the modern-day green buildings due to their unpopularity and the unavailability of design guidelines. On the basis of the findings of the literature review, stakeholders and the public are encouraged to adopt water wall systems in green building projects as an energy-efficient strategy and a fire safety mechanism.
