“…One issue noticeable in the LCA results for both office types is the high environmental impact of the production stage in the optimal case induced by the manufacture of the PCM. This is a common conclusion in previous studies that have evaluated the manufacture and disposal phases of PCM . Furthermore, the impact of the energy use stage decreases for all the damage categories in the optimal scenario compared to the reference construction case in both office units, undivided and subdivided.…”

“…For this purpose, values on energy, raw materials, water consumption, air emissions, and solid waste production are collected by measurement from other databases, from in situ surveys or from calculations. All the aforementioned values are converted into environmental indicators such as climate change, acidification, eutrophication, and photochemical oxidation . A huge amount of data is needed for assessing the impact, as this involves complex environmental modeling which produces the final environmental impact indicators .…”

Summary The investigation of the use of phase change materials (PCM) in the building sector has become a significant issue and a field exhibiting significant potential in terms of research and development. The present study evaluates the integration of PCMs in office buildings on the basis of their economic and environmental performance by means of life cycle analysis (LCA) in conjunction with life cycle cost analysis (LCCA) respectively. This study is based on a previous building envelope multiobjective optimization study which considers cooling load requirements and thermal comfort conditions as optimization objectives. Specifically, this work moves 1 step further to evaluate the optimal results obtained from the above‐mentioned optimization study based on economic and environmental aspects. This paper attempts to evaluate and quantify the environmental and economic potential of PCM use in office buildings in a generic way. In detail, the present study starts by examining whether reducing the extent of the environmental impact achieved during the operational phase from energy savings offsets the respective increase arising from the PCM production. The LCA results reveal that the overall life cycle impact of the 2 office units examined is reduced, despite the respective impact of the construction stage increasing significantly, given the high proportion of impact accruing from the energy use stage in the overall impact. Finally, a life cycle cost evaluation assesses the viability of such applications, with the conclusion that the energy saving achieved during the use stage in both office units is insufficient to compensate for the LCC increase induced by the high cost of construction.

“…Of these, paraffin accounts for approximately 45% of all PCMs used . Life cycle analysis of paraffin used as PCMs in building applications shows that the environmental impact can be compensated over 61 years of use . Therefore, substitutes from renewable feedstock with less environmental impact are highly desirable.…”

Lipid‐derived monoamide as phase change energy storage materials

et al. 2019

Summary One of the major shortcomings of current organic phase change materials (PCMs) is their relatively low melting points, typically below 80°C, which limits their integration into thermal energy storage (TES) systems. The present work was aimed at developing lipid‐derived PCMs with increased melting points which would be suitable for TES applications requiring higher melting points without compromising other key properties such as enthalpy. The introduction of an amide group into the structure of linear saturated fatty acids was used as a means to increase intermolecular interactions and therefore crystallization and melting points. A series of six linear monoamides with differing chain length and symmetry about the amide group were investigated for thermal stability, thermal transition, flow behavior, and crystal structure to establish the structure‐property relationships relevant to TES. The presence of the highly polar amide group in the aliphatic fatty acid–derived molecules resulted in notable improvement in performance compared with the analogous monofunctional molecules: Increases in melting points (79°C‐96°C) and high enthalpies of fusion (155‐201 J/g) were recorded. Fundamental relationships between structure, processing, and macroscopic physicochemical properties, never before elucidated, were revealed in the study. The study revealed a step‐like variation of macroscopic properties: a surprising outcome of the competition between intermolecular attractions, symmetry effects, and mass transfer limitations. The predictive structure‐function relationships established in this work will allow the straightforward engineering of monoamide architectures that can extend the range of organic PCMs and deliver thermal properties desirable for TES applications.

Summary Phase change materials (PCMs) contributed to building energy‐saving and thermal comfort through increasing the thermal capacity of building envelopes. In this study, a phase change material composite was developed by using the PCMs mixture of capric acid (CA) and lauric acid (LA) as the primary phase change energy storage agent and using the solid waste fly ash as a carrier material. The results showed that for Guangdong, the ideal PCMs mixture should have a transition temperature of 25.5oC, which could be obtained by using a mass ratio of CA/LA of 4:6. Then, experiment results also indicate that the optimum adsorption ratio of 2:1 (FA/PCMs) was detected for the synthesis of this FA/PCMs composite, which has the latent heat of 45.38 J/g and exists excellent thermal reliability. Moreover, simulation results by using EnergyPlus show that the proposed composite has a good building energy‐saving effect.
