“Green” buildings constructed by bio-based materials have been considered as a strategy to battle the climate changes. In this regard, engineered wood such as cross-laminated timber or glulam is increasingly used in building applications (Asdrubali et al., 2017). In order to take more advantage of its attractive properties, wood as a natural porous material could be used as a substrate to encapsulate organic bio-based phase change materials (OBPCMs) to improve the thermal mass of buildings. Various OBPCMs have been tested to store and release solar energy (Mathis et al., 2018, Mathis et al., 2019). However, in Nordic countries there is deficiency of sunny days in winter when the demands for energy is high and thus, using OBPCMs incorporated into wooden materials to control indoor temperature fluctuations can be presented as an alternative. Permeable wood and wood-based materials could be used to cost effectively shape stabilize the OBPCMs to enhance its thermal and chemical capabilities of using these materials in building envelopes (Yang et al., 2019).
