Recycled and ecological materials
Published in Arthur Lyons, Materials for Architects and Builders, 2019
An alternative approach to using load-bearing straw bales is illustrated in the University of Nottingham Gateway Building on the Sutton Bonington Campus. The building is constructed from panels each comprising a cross-laminated timber frame filled with compressed straw and externally rendered with a breathable coating (Fig. 17.2). Manufacturers are producing a variety of structural insulated panels (SIPs) incorporating straw insulation. While fire is a risk during straw bale construction, the non-combustible internal and external finishes and the compact nature of the straw make the completed construction resistant to fire. (The thermal conductivity of baled straw is approximately 0.050 W/mK.)

With increasing emphasis on bio-based construction materials, LCA studies on energy consumption and the GHG emissions of engineering materials produced from wood, bamboo, and straw bale are increasing (Lin, Chiang, Weng, & Wu, 2023). For instance, Zea Escamilla et al. (2018) put forward that bamboo as a construction material has great potential for sustainable development after performing a life cycle assessment of bamboo and traditional building materials. Jayalath et al. (2020) found that CLT mid-rise residential buildings produce from 29 to 34% less GHG emissions than reinforced concrete buildings respectively. Yin, Yu, Dong, Jia, and Sun (2020) studied the energy sustainability of bio-based residential buildings in the severe cold regions of rural China and concluded that reductions of 45.82–204.07 kWh/m2/year in heating energy requirements and over 40% in coal use are possible through the application of straw bale construction.
How can carbon be stored in the built environment? A review of potential options

Straw is a typical residue from agriculture that has been used for construction purposes since time immemorial. The most typical modern construction uses include straw bales that are attached between loadbearing timber studs or straw-clay mix that can be cast into different structures. The carbon storage potential of straw bale construction has been studied and compared to that of biochar (Mattila et al. 2012) to typically used bricks or blocks (Gonzalez 2014), and to other typical building materials (Sodagar et al. 2010). Although straw in construction is to a certain extent vernacular, it is widely used, thus allowing it be ranked at TRL 9.
