Forum Bauinformatik, fbi 2024: 300-307https://hdl.handle.net/11420/49646The paper examines code compliance of energy efficiency in building design through (BIM) tools, particularly the BIMQ – Solibri rule plugin and a custom-created Solibri ruleset. It aims to simplify the validation of thermal transmittance (U-value) for architectural components such as doors, slabs, walls, and windows, ensuring these elements fulfil the established energy efficiency standards. The BIMQ plugin in Solibri Model Checker (SMC) effectively assigns and confirms thermal transmittance values across different components while identifying errors in the BIM model in Autodesk Revit. Furthermore, the model checking with the custom ruleset facilitates the assessment of components against energy efficiency rule criteria in the paper by pointing out the components that need adjustments to improve the whole building's performance and their exact locations. Using an Excel template to export the results from (SMC) makes analyzing the data simpler for stakeholders. The project highlights the significant importance of BIM in the construction sector especially in achieving energy efficiency objectives and it sets the foundational basis for future improvements in BIM technologies to further improve the consistency and efficiency with the AEC industry while acknowledging challenges and inaccuracies in component classification in the model that require further improvement.enhttps://creativecommons.org/licenses/by/4.0/BIMBIMQCode ComplianceEIREnergy EfficiencySolibri Model CheckerArts::720: ArchitectureTechnology::690: Building, ConstructionTechnology::620: Engineering::620.2: Acoustics and NoiseComputer Science, Information and General Works::004: Computer SciencesConference Paper10.15480/882.1353810.15480/882.13538Conference Paper
