Integration of Building Information Modeling (BIM) and LEED's Location and Transportation Category
The selection and development of a project location is critical to the success of a green building project. LEED (Leadership in Energy and Environmental Design) is one of the most popular Green Building certification systems in the world. Traditionally in LEED design, architects and designers have to analyze project location based on traditional maps with manual calculations, which require a significant amount of time and effort. In the meantime, the advent of Building Information Modeling (BIM) has brought about a promising new way of improving Green Building’s location analysis. This research presents an integration model of BIM in LEED certification to improve the efficiency of LEED’s location and transportation analysis. The framework of the integration model is introduced and demonstrated using a user interface for LEED’s analysis under the Autodesk Revit environment.
Integration of Building Information Modeling and Web Service Application Programming Interface for assessing building surroundings in early design stages
Abstract Many studies and green building rating systems have addressed the social and environmental importance of site planning. Tools based on BIM and Location Based Services (LBSs) have been developed to estimate energy consumption for material transportation and the surrounding density of the sites. However, the tools are not programmable and limited by their serving phases. This requires solutions that have the flexibility to run site analysis on social surroundings and the compatibility of user programming in the early design stage. Integrating visual programming and web service Application Programming Interface (API) can fulfill the requirements of evaluating publicly available diverse uses of sites and custom coding. This study introduces the method for integrating Dynamo BIM and Amap web service APIs for the evaluations of publicly available diverse uses and transportations. Additionally, implementations of use cases are demonstrated including assessments of Access to Quality Transit and Diverse Uses in LEED v4. Results from the integrated tool are analyzed and validated with survey results. The analysis of results indicates that the integration method introduced in this paper is effective. The limitations, potentials, and future developments are also discussed. The integration of Dynamo BIM and web service APIs might be useful for site assessments in the early design stage or even earlier.
Computer-Aided System of Virtual Testing of Gas Turbine Engines
The article describes the concept of a virtual lab that includes subsystem of gas turbine engine simulation, subsystem of experiment planning, subsystem of measurement errors simulation, subsystem of simulator identification and others. The basis for virtual lab development is the computer-aided system of thermogasdynamic research and analysis “ASTRA”. The features of gas turbine engine transient modes simulator are described. The principal difference between the simulators of transient and stationary modes of gas turbine engines is that the energy balance of the compressor and turbine becomes not applicable. The computer-aided system of virtual gas turbine engine testing was created using the developed transient modes simulator. This system solves the tasks of operational (throttling, speed, climatic, altitude) characteristics calculation, analysis of transient dynamics and selection of optimal control laws. Besides, the system of virtual gas turbine engine testing is a clear demonstration of gas turbine engine working process and the regularities of engine elements collaboration. The interface of the system of virtual gas turbine engine testing is described in the article and some screenshots of the interface elements are provided. The developed system of virtual gas turbine engine testing provides means for reducing the laboriousness of gas turbine engines testing. Besides, the implementation of this system in the learning process allows the diversification of lab works and therefore improve the quality of training.
