ABSTRACT This work consists of the applications of solar energy or solar heater on building construction practices, with the help of natural circulation loop designs driven by heat transfer processes to develop an innovative curtain wall integrated solar heater using nanofluid based on the theory of an energy-harvesting façade. This prototype was tested experimentally with the various heat transfer processes. Nanofluids have unique features different from conventional solid-liquid mixtures and due to their excellent characteristics, nanofluid find wind applications in enhancing heat comprehensive research on the thermal performance of an innovative curtain wall integrated solar heater by improving the heat transfer properties of the solar heater by using Nanofluid as a working fluid which has superior thermal properties compared with water.

1. INTRODUCTION Solar thermal energy can beneficially trap and preserve by various devices and designs that are efficient of harvesting solar energy in buildings through the use of for example a low power thermo-electric material or a hot water system (Chi-ming Lai, Shuchi Hokoi 2014). In buildings for solar energy usage Thermal Energy Storage (TES) is an essential unit, and it is one of the sustainable and optimistic systems for energy storage. There are three important types of TES (Thermal energy storage) systems operated in buildings which are easily categorized as follows: sensible. latent, and thermochemical energy storage. Water is generally utilizing because of its high thermal capacity, the extensive scope of storage temperatures, nontoxicity, low cost, and easily accessible in solar water heating for domestic use (C. Dharuman, J. H. Arakeri 2006; P. Li. J. Liu 2011). Although, in SWH Systems further valuable integration of solar collection is always beneficial in building constructions (Chi-ming Lai, RongHorng Chen 2012). Compared to standard liquid and standard 2 phase mixture, the nanofluid does not obstruct flow channels, has higher thermal conductivity and impels a slight pressure drop. In comparison to larger particles nanoparticles withstand settling due to Brownian motion and higher surface area which enriches the heat conduction of nanofluids and interparticle forces. The various properties of nanofluids like increase single-phase heat transfer, increased thermal conductivity, and increased critical heat flux makes them promising coolants. In 2012 Rodriguez-Hidalgo Studied the domestic hot water use for solar collectors’ performance by utilizing solar facilities (M. C. Rodriguez-Hidalgo 2012). Heat losses calculated with the help of a single storage tank by
