The use of nanofluids in building materials for energy efficiency and optimization in buildings

This study presents a methodology for investigating the thermal properties and energy efficiency improvements offered by nanofluids when used in building materials. The research focuses on nanofluids containing Silica (SiO۲), Alumina (Al۲O۳), and Carbon Nanotubes (CNTs) dispersed in a water/ethylene glycol base fluid. The nanofluids were synthesized using the two-step method, ensuring stable dispersion through ultrasonic agitation and surfactants. An experimental setup, including a liquid-to-air heat exchanger, temperature sensors, and flow meters, was utilized to measure the thermal performance of the nanofluids. Computational models incorporating formulas for effective density, specific heat capacity, and thermal conductivity were developed to predict thermal performance and validated against experimental results. The findings indicate significant improvements in thermal conductivity and heat transfer efficiency, demonstrating the potential of nanofluids to enhance energy efficiency in HVAC systems and building materials. This study underscores the importance of ongoing research and innovation in nanotechnology to overcome challenges related to stability and production costs, paving the way for the broader adoption of nanofluids in sustainable construction practices.
