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.

Summary Building envelopes incorporating phase change materials (PCMs) can contribute to reducing the energy consumption of buildings and enhance indoor thermal environment comfort. In this study, two building models were developed in EnergyPlus to explore the applicability of using PCMs in different climate zones. Six significantly different cities from five climate zones in China have been investigated. The simulation results reflected that for climates with small fluctuation weather conditions, PCMs with appreciate transition temperature TR can contribute to positive influences on energy saving. For example, in Guangzhou, PCMs with TR of near 26oC and 22oC contribute to the highest energy‐saving rates of 12.0% and 12.4%, for external and internal PCMs addition. And the ideal transition temperature for each climates is subjected to its own outdoor comprehensive temperatures and its indoor set temperature, for external and internal PCMs addition, respectively. For other climates with the big fluctuation weather condition, PCMs' latent heat function to the energy savings is not significant.

Green Cementitious Composites Made with PCM-Recycled Brick Aggregates: Thermal Energy Storage Characterization and Modelling

This work reports the results of an extensive experimental campaign aimed at investigating the Thermal Energy Storage (TES) behavior of PCM Recycled Brick Aggregate (RBA) mortars. Test specimens for TES measurements were produced following a new spherical-shaped technique, patented as "DKK test" by the Institute of Construction and Building Materials of TU-Darmstadt. DKK was used for TES characterizing the various test samples made of plain cement paste plus porous RBAs, these latter filled with paraffinic PCM waxes. Dynamic DSC tests and conductivity measurements were also done for thermally investigating both components and composites. Moreover, the study proposes a novel numerical approach for determining the energy storage capacity of the investigated systems, setting the experimental benchmarks which were used for validation purposes. Particularly, the experimental results have been finally employed for calibrating an enthalpy-based model, at both macro-and meso-scale level, to evaluate the temperature-based thermal parameters like specific heat, conductivity, or more in a general sense, the energy storage capacity of these systems under transient heat conduction conditions. The results show very promising possibilities for using RBAs as carriers in green concrete applications.
