“…11 For building envelopes, the strict energy-saving standards are based on the value of the two thermal properties of the envelope materials, ie, thermal conductivity and thermal capacity. [12][13][14][15] Phase change materials (PCMs) can effectively improve the thermal inertia of materials because of their huge latent heat, so PCMs have received much attention in the recent energy-saving applications and research of building envelopes. For example, Boussaba 16 synthesized a PCM's composite with low-cost and eco-friendly for the application in building envelopes.…”

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.

“…Existing literatures have given two main types of energy efficient wall systems, namely, high-thermal insulation system [6][7][8][9] and thermal storage system, eg, using phase change materials (PCMs). [10][11][12][13][14][15] The use of thermal energy storage for building envelops has received great attention in recent years. 16 Numerous studies have explored the use of PCMs in building envelopes to enhance the indoor thermal environment and energy performance of buildings.…”

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.

“…This phenomenon can be explained by increased demand for thermal comfort due to increased standard of living in most parts of the world [2]. Another factor that might increase the installed cooling capacity in the future is highly insulated and air-tight buildings and climate change [3]. It has been reported that retrofitted and newly constructed highly insulated buildings experience more overheating even in Nordic countries due to internal and external heat gains [4].…”

As building codes are pushing towards higher energy efficiency and the arrival of nearly Zero Energy Building (nZEB) requirements for all new buildings are just around the corner the need for alternative, high efficiency heating and cooling solutions for nZEB’s is greater than ever. Also as experience with renewable energy sources has proven the energy demand and energy generation rarely overlaps and it does not allow to fully utilise some renewable energy sources. This is a simulation study that focuses on integrated cooling and energy storage system utilising phase-change materials (PCM). Several types of thermally activated slabs with different PCM thicknesses were simulated in order to find the most optimal PCM thickness with melting point temperature that can support passive cooling methods based on adiabatic cooling principles. Two calculation tools were used for the study – IDA ICE 4.8 and U-NORM 2012-2 to calculate the properties of the slabs and potential of application in well insulated residential building in Baltic climate. The results showed that the optimal thickness for thermally activated PCM layer (large flat containers) range from 25 mm to 90 mm, and for layers with no thermal activation – 180 mm and more. Moreover the results show that apart from energy storage the thermally activated panel can increase thermal comfort conditions.
