Abstract: This study presents a numerical investigation of a 3D printed building envelope made of cementitious mortar enhanced with phase change material (PCM) nanoparticles. The aim is to assess its thermal performance under summer condition for a Mediterranean climate. The 2D section of the wall is designed to have multiple concrete layers, alternating with air cavities. The natural convection within the internal cavities of the envelope is optimized to enhance thermal insulation. A comparative analysis is performed between a baseline configuration without PCMs and a modified configuration containing PCM-enhanced mortar. The numerical simulations demonstrate the effectiveness of PCM integration in increasing thermal inertia and reducing indoor temperature fluctuations, contributing to improved energy efficiency in buildings across a summer period of 12 days.
