Comparative study on computer simulation of solar shading performance with heliodon and artificial sky

Current technological advancement and the requirement for sustainability-driven practices has birthed increased demands for accuracy in performance and assessment of energy consumption in the built environment. Energy-efficient and sustainable building projects are to large extents dependent on achieving functional solar shading and sufficient daylighting in building interiors. Hence, the understanding and adequate evaluation of the sun and its dynamic influence on buildings right at the early stage of planning and design is essential for the development of performance-driven building designs. In this study, the performance simulation results of Integrated Environmental Solutions [removed] software program modules are examined for accuracy in executing performance analysis of solar shading. This study assesses the shading prediction of Suncast; a virtual solar shading calculation tool, and RadianceIES for measuring daylight availability in a tropical climate region. The evaluation of shading performance with Suncast was validated through physical experiment by comparing the results obtained therein with shading analysis outcomes generated on a scale model with the aid of a heliodon. Likewise, RadianceIES daylighting simulations were compared with measurements realised from an artificial sky simulator. The results were further subjected to correlation tests to determine the relationship between simulation and physical experiment results. The computational evaluation approach presented more efficient means of conducting the performance simulations over the physical experiment methods which were limited by mechanical design of the components. Suncast and RadianceIES simulation results presented comparable equivalence with measurement output acquired from the heliodon and artificial sky respectively, with minimal variations in accuracy. Thus, demonstrating the ability of the computational simulation program in accurately predicting solar shading and daylight performance in buildings, this could benefit architects in the proper and efficient design of shading devices for building facades at early design stages

African BIM Report 2020

While it may seem like the adoption of Building Information Modelling (BIM) across Africa is slow-paced, the increasing advocacy efforts from various stakeholders is now resulting in a widespread drive for implementation and deployment. Coupled with the ongoing disruption by the global COVID-19 pandemic, there is now a very high degree of the utilization of digital technologies by construction professionals. As a first of its kind across the continent, the African BIM Report was conceived to provide a continuous review of the state of implementation of BIM by the industry. The report will progressively highlight exceptional projects, industry leaders and research experts across Africa. A pan-African survey will integrate the opinion from a wider range of professionals. As a dynamic, future-focused, and thriving community, BIM Africa is well-positioned to champion the digital transformation of the built industry across Africa. Our approach covers broad industry education, extensive research, professional development and certifications, quality networking and the formulation of locally adapted standards. Our Research and Development Committee comprises of a thriving portfolio of internationally certified and brilliant academic researchers of African descent; the coming together of bright minds to impact their motherland
