Excessive heat accumulation is one of the main challenges in office buildings with curtain wall systems. This challenge requires a staggering amount of cooling energy, especially in desert and temperate climate zones. Hence, an effective and practical shading device is necessary to address this issue using a bio-inspired strategy to reduce cooling energy consumption and enhance sustainability. This study uses a Bio-Curvilinear Shading Device (Bio-CSD) to improve cooling energy efficiency, cost-effectiveness and CO2 reduction in the desert and temperate climate zones in Iraq. To alleviate overheating issues, we designed a Bio-CSD and a modified Bio-Curvilinear Shading Device (mBio-CSD) from a cactus, namely the Ogonchu plant (Pilosocereus chrysostele). Fifty-one scenarios were investigated to examine the prevalence of three distinct office building typologies: linear [T1], concentric [T2], and courtyard [T3]. The Bio-CSD and the mBio-CSD were simulated using a novel energy simulation framework for curvilinear shading devices using IDA Indoor Climate and Energy (ICE) software v4.8. Our findings revealed that the Bio-CSD outperforms a Rectilinear Shading Device (RSD) under identical conditions with the same surface area. The Bio-CSD allows maximum cooling energy savings of 31 %, 24 %, and 22 % and 23 %, 19 %, and 16 % for the three office building typologies (T1, T2 and T3) in temperate and desert climate zones, respectively. Our Bio-CSD can be a cost-effective and eco-friendly solution to mitigate overheating issues while ensuring more natural light penetration during winter, with reduced material use and lower costs.
