• Porosity and mPCM fraction served as design variables in optimizing the building energy consumption for indoor thermal comfort. • Application to a demo-building such as the BESTEST 900 (ANSI/ASHRAE Std 140-2017), virtually located in Bilbao, demonstrated the benefit of the proposed NRG&STRUCT-foam in comparison to the original configurations. • Optimization recommend the integration of mPCM within non-porous layers for effective TES enhancement, while avoiding the inclusion of mPCM within porous foamed concrete. Future research will expand to various building types and locations, with a focus on broader recommendations and structural safety considerations.
