Abstract Transparent wood (TW) with excellent optical and thermal management performance has been developed recently as a promising energy-efficient building material. Here, an editable shape-memory TW (ESMTW) is developed through in situ polymerization of epoxy vitrimers into a delignified wood scaffold. The ESMTW possesses high strength at low temperature and flexibility at high temperature, while it exhibits excellent shape-manipulation capability under thermal-stimulus. Meanwhile, the ESMTW shows unique light guiding and directional scattering effects. The light illuminance difference observed in our house model with a common glass ceiling is 81 times, whereas it is only 16 times with a ceiling made of the ESMTW. Most importantly, the transmitted light intensity distribution is tunable owing to its shape-management capability. Additionally, the resultant TW possesses great thermal insulation properties, mechanical strength, and high impact absorption ability. The combination of characteristics enables TW to exhibit great promise as an advanced functional and intelligent building material.
