Automatic building information model query generation

Energy efficient building design and construction calls for extensive collaboration between different subfields of the Architecture, Engineering and Construction (AEC) community. Performing building design and construction engineering raises challenges on data integration and software interoperability. Using Building Information Modeling (BIM) data hub to host and integrate building models is a promising solution to address those challenges, which can ease building design information management. However, the partial model query mechanism of current BIM data hub collaboration model has several limitations, which prevents designers and engineers to take advantage of BIM. To address this problem, we propose a general and effective approach to generate query code based on a Model View Definition (MVD). This approach is demonstrated through a software prototype called QueryGenerator. By demonstrating a case study using multi-zone air flow analysis, we show how our approach and tool can help domain experts to use BIM to drive building design with less labour and lower overhead cost.published_or_final_versio

BIM-based processes and standardized information exchanges for multizone airflow analysis

Multizone airflow analysis is an important tool for analyzing the performance of a building from the perspective of ventilation, contaminant transport, and indoor air quality. However, many airflow modeling and simulation applications such as CONTAM do not allow for easy input of previously developed model contents, which hinders their effectiveness. Consequently, in the current practice engineers commonly need to rebuild a multizone model of the target building, although the majority of the required information has been already produced and available. This is time consuming and may result in differences between the original model and the analysis model. In order to successfully implement the integrated building design process using a Building Information Model (BIM) to address the deficiencies, this paper presents processes to illustrate detailed workflows along with key decision making points, and exchange requirements identified within the processes. This efforts facilitates the implementation of BIM into an integrated building design process by contributing to the automation of information extraction from the BIM model and generation of its airflow analysis model

EIC Physics from An All-Silicon Tracking Detector

The proposed electron-ion collider has a rich physics program to study the internal structure of protons and heavy nuclei. This program will impose strict requirements on detector design. This paper explores how these requirements can be satisfied using an all-silicon tracking detector, by consideration of three representative probes: heavy flavor hadrons, jets, and exclusive vector mesons.Comment: 48 pages, 55 figure
