Abstract
Due to growing consciousness regarding the environmental impact of fossil-based and non-sustainable materials in construction and building applications, there have been an increasing interest in bio-based and degradable materials in this industry. Due to their excellent chemical and thermo-physical properties for thermal energy storage, bio-based phase change materials (BPCMs) have started to attract attention worldwide for low to medium temperature applications. The ready availability, renewability, and low carbon footprint of BPCMs make them suitable for a large spectrum of applications. Up to now, most of the BPCMs have been incorporated into inorganic matrices with only a few attempts to set the BPCMs into bio-matrices. The current paper is the first comprehensive review on BPCMs incorporation in wood and wood-based materials, as renewable and sustainable materials in buildings, to enhance the thermal mass in the environmentally-friendly buildings. In the paper, the aspects of choosing BPCMs, bio-based matrices, phase change mechanisms and their combination, interpretation of life cycle analyses, and the eventual challenges of using these materials are presented and discussed.
Highlights
Due to an increase in global population and technological development, the demand for energy has experienced a significant growth over recent decades
based phase change materials (BPCMs) are intended for use in indoor environments, biological durability as well as fire resistance are important challenges that need to be addressed if plant fibers, wood, or wood-based composites are used as matrices for phase change materials (PCMs) in building applications
This review focuses on the incorporation of BPCMs in lignocellulose materials for thermal energy storage in building applications
Summary
Due to an increase in global population and technological development, the demand for energy has experienced a significant growth over recent decades. These new solutions should involve environmentally-friendly strategies to avoid negative impact on the environment To meet these demands, thermal energy storage in the form of latent heat energy storage in bio-based phase change materials (BPCMs) has a role to play. Thermal energy storage in the form of latent heat energy storage in bio-based phase change materials (BPCMs) has a role to play Due to their unique chemical, thermal, and physical properties, BPCMs are promising materials for fulfilling the above-mentioned requirements. Using bio-based materials as PCMs in combination with wood as matrices can address both managing energy consumption and environmental concerns about buildings [7,8,9]. In a specific range of temperature, PCMs store and release energy in terms of latent heat during the phase transition. When the temperature drops down, the material releases the energy and, returns to its initial phase state [11,19]
