“…These types of design proved to be beneficial in lightweight construction along with the efficient performance of the PCM. Advanced models of composite walls with PCM blended into the composition of construction materials, provided the PCM composite with a shape stability, mechanical strength and latent storage characteristics [10,11]. The simulations on the models concluded that the model sticks well with the latent storage characteristics of the PCM blended in it.…”

Phase Change Materials (PCMs) are capable of reducing the thermal load transfer rate between outdoors and indoors and maintain stability in the indoor temperature when used in building applications. In this study, a variation of layers of two Bio-PCMs integrated with layers of general construction material and insulation have been analyses discretely as well as in combination. The observations from various models have been compared to draw the result and perceive the best model of a Bio-PCM wall for constructing thermally efficient buildings. The wall models have been created and analyzed through Computer Aided Design (CAD) modeling and simulation techniques using Transient Thermal module in ANSYS software. Coconut fat and Palm fat being highly efficient and easily available Bio-PCMs, are used in this study and attractive results have been obtained from them.

“…This enormous increase was a consequence to the growth in world's population that stimulated the evolution of economy and energy demand [1]. Buildings proved to be accumulating for the largest energy consumption quantity world-widely, with a percentage ranging between 30-40% 1 [2][3][4][5], that is expected to rise up by 2050 reaching 50% [6]. The majority of energy consumed within the building sector is directed toward heating and cooling systems.…”

“…Results showed that the thermal performance of the system with PCM was enhanced were thermal comfort was increased as the temperature fluctuations in vertical indoor environment decreased. In a comparative study directed toward investigating the effect of combining active and passive PCM applications, Kong et al [5] managed to introduce a novel system composed of PCM wallboards (passive) prepared from paraffin and EP, and a heat accumulator (HAR) filled with PCM coupled to a solar heating system used as a radiating wall. Two identical test cubicles of 1 m edge size comprising a window were prepared and tested under different stages.…”

The use of phase change materials in buildings as a thermal energy storage system gained the attention of researchers all over the world. In the current study, coconut oil bio-based PCM is macro-encapsulated with enhanced thermal conductivity containers and coupled with hydronic radiant floor heating system. The study follows experimental aspect utilizing two identical small scale modular test prototypes. Investigations are directed toward studying the effect of the active CO-PCM system under different weather conditions, effect of combining active and passive systems, effect of PCM choice/type and effect of PCM location within the active floor, on the thermal and energy storage performances. Results revealed that coupling CO-PCM to active floor, passive wall and passive roof is capable of achieving load shifting and energy savings; and is affected by the control method, weather conditions, electricity tariff policy and PCM position and type. Further discussions, conclusions and perspective recommendations are summarized within the article. Highlights Identical experimental advanced modular prototypes are designed and implemented.  Macro-encapsulation technique using enhanced thermal conductivity containers.  Thermal comfort and temperature fluctuations reduction using CO and PW PCMs.  Load shifting by combined CO-PCM applications leads to possible annual cost saving.  Positioning CO-PCM plates below heating layer ensued energy saving of 393.5 kWh.

“…If these methods used permanent installations, such as buildings constructed with a high thermal mass, then benefits could have been lost when a low thermal capacitance is favorable. Due to this, investigations into active thermal mass and thermal storage methods are of interest [14][15][16][17][18][19]. Carpenter et al [16] found building energy consumption reduced when implementing increased thermal capacitance though water circulation in the shell of the building.…”

“…This paper aims to address this issue by introducing phase change materials (PCM) to a water storage tank to reduce tank size with only small reductions to heat storage capacity. Kong et al [18] and Whiffen et al [15] both conducted experiments showing the validity of integrating PCMs for increased thermal mass, Kong et al through passive PCM wallboards, and Whiffen et al though an active hollow slab with embedded PCM. Whiffen et al were able to show a delay in AC onset by 1.2 h. The impact of PCM on building energy consumption has also been studied using numerical simulations using software such as the Transient System Simulation Tool (TRNSYS [20]) [21][22][23][24], which was also used in this paper's study.…”

This study simulates an increased thermal capacitance (ITC) and thermal storage management (TSM) system to reduce the energy consumed by air conditioning and heating systems. The ITC/TSM is coupled with phase change materials (PCM), which enable tank volume reduction. The transient energy modeling software, the Transient System Simulation Tool (TRNSYS), is used to simulate the buildings' thermal response and energy consumption, as well as the ITC/TSM system and controls. Four temperature-controlled operating regimes are used for the tank: building shell circulation, heat exchanger circulation, solar panel circulation, and storage. This study also explores possible energy-saving benefits from tank volume reduction such as losses associated with the environment temperature due to tank location. Three different tank locations are considered in this paper: outdoor, buried, and indoor. The smallest tank size (five gallons) is used for indoor placement, while the large tank (50 gallons) is used either for outdoor placement or buried at a depth of 1 m. Results for Atlanta, Georgia show an average 48% required energy decrease for cold months (October-April) and a 3% decrease for warm months (May-September) for the ITC/TSM system with PCM when compared with the reference case. A system with PCM reduces the tank size by 90% while maintaining similar energy savings.
