This study aims to quantify the impact of Thermal Energy Storage (TES) measures on a building's heating and cooling demands, particularly focusing on system efficiency and boiler cycling. Through thermodynamic analysis and modeling of TES systems with varying storage capacities, this research aims to showcase the potential of TES in optimizing peak thermal loads, consequently reducing the required boiler or chiller capacity and enhancing overall thermal system efficiency.

The prepared nanocomposites have been characterized by FTIR and XRD for structural analysis. FTIR spectra show the important peaks of CaTiO 3 and PVA which confirms the formation of nanocomposites. XRD pattern shows that the CaTiO 3 has orthorhombic structure and its crystal structure does not distorted even after dispersion in PVA matrix. The TGA graph confirms that the addition of CaTiO 3 (0.3 wt%) enhance the thermal stability of the nanocomposites. Further, the temperature dependent conductivity shows the increase in conductivity due to the tunnelling of charge carriers. Dielectric constant and dielectric loss of the 0.3 wt% of nanocomposites is low compare to other nanocomposites and hence its conductivity is high. It is found that the damping loss is 0.002% as indicated in quality factor and tangent loss is almost constant after 10 4 Hz which indicates that these nanocomposites can be used as low k-dielectric materials in electronic application.
