Abstract: Phase change material (PCM) enhanced wall assemblies can control indoor temperatures and save energy. However, PCM needs to change the phase to be fully effective. The integration of PCMs into building envelopes typically requires mixing with other materials. This research aims to advance the existing knowledge on incorporating PCM into carbon-neutral wall assemblies made of hempcrete and investigating temperature control strategies to improve wall systems' performance during the heating season. A 30 cm hempcrete and hempcrete-PCM walls were simulated in Fluent under Ottawa weather conditions and compared under different temperatures control strategies. Overall the hempcrete-PCM (HPCM) enhanced wall outperformed the hempcrete wall during the heating season.
