Abstract
3D modeling of indoor spaces is a prerequisite for daylight simulation, and the accuracy of the 3D models has a significant impact on the simulation. The goal of this study was to quantify the errors caused by modeling indoor spaces at different accuracy levels to find the optimal balance between the reliability of the results and labor investment. For this purpose, we introduce a level of detail (LOD) concept for indoor spaces based on the size of non-permanent indoor objects by inclusion and exclusion from the simulation scene. The errors corresponding to models with low accuracies are measured by climate-based simulation using an improved two-phase method. Our results show that inaccurate modeling of indoor spaces causes between 10-70% error in TAI with 25% median across all spaces.

| Other | Following the successful BS2021 in Bruges, Shanghai will take the relay in hosting the next worldwide Building Simulation Conference! BS2023 will see the return of the conference to China after 16 years. The regional affiliate, IBPSA-China, is honored to present an efficient, interactive, warm and safe reunion to the community. Please subscribe to our mail list to stay informed. BS2023 continues to be a Hybrid event. However, with all travel restrictions to China lifted, we highly recommend you to attend in person, for a better social networking experience and a great chance to explore the mainland China. |
