title	Optimo: A BIM-based Multi-Objective Optimization Tool Utilizing Visual Programming for High Performance Building Design
doi	https://doi.org/10.52842/conf.ecaade.2015.1.673

summary	Within the architecture, engineering, and construction (AEC) industry, the application of multidisciplinary optimization methods has been shown to reach significant improvements in building performance compared to conventional design methods. As a result, the use of multidisciplinary optimization in the process of design is growing and becoming a common method that provides desired performance feedback for decision making. However, there is a lack of BIM-based multidisciplinary optimization tools that use the rich information stored in Building Information Models (BIM) to help designers explore design alternatives across multiple competing design criteria. In this paper we introduce Optimo, an open-source visual programming-based Multi-Objective Optimization (MOO) tool, which is developed to parametrically interact with Autodesk Revit for BIM-based optimization. The paper details the development process of Optimo and also provides the initial validation of its results using optimization test functions. Finally, strengths, limitations, current adoption by academia and industry, and future improvements of Optimo for building performance optimization are discussed.

title	A New Implementation of Head-Coupled Perspective for Virtual Architecture
doi	https://doi.org/10.52842/conf.caadria.2015.251
source	Emerging Experience in Past, Present and Future of Digital Architecture, Proceedings of the 20th International Conference of the Association for Computer-Aided Architectural Design Research in Asia (CAADRIA 2015) / Daegu 20-22 May 2015, pp. 251-260
summary	The process of projecting 3D scenes onto a two-dimensional (2D) surface results in the loss of depth cues, which are essential for immersive experience in the scenes. Various solutions are provided to address this problem, but there are still fundamental issues need to be addressed in the existing approaches for compensating the change in the 2D image due to the change in observer’s position. Existing studies use head-coupled perspective, stereoscopy, and motion parallax methods to achieve a realistic image representation but a true natural image could not be perceived because of the inaccuracy in the calculations. This paper describes in detail an implementation method of the technique to correctly project a 3D virtual environment model onto a 2D surface to yield a more natural interaction with the virtual world. The proposed method overcomes the inaccuracies in the existing head-coupled perspective viewing and can be used with common stereoscopic displays to naturally represent virtual architecture.

title	Parametric BIM-based Energy Simulation for Buildings with Complex Kinetic Façades
doi	https://doi.org/10.52842/conf.ecaade.2015.1.657
source	Martens, B, Wurzer, G, Grasl T, Lorenz, WE and Schaffranek, R (eds.), Real Time - Proceedings of the 33rd eCAADe Conference - Volume 1, Vienna University of Technology, Vienna, Austria, 16-18 September 2015, pp. 657-664
summary	This paper aims to investigate a new methodology for analysing energy performance of buildings with complex kinetic façades. In this research, the flexible movements of individual kinetic façades in a building is determined by the façades' opening ratios and the sun path. The platform development is conducted through a visual programing environment in BIM, and the process is presented with a case study. Finally, the building's energy performance is compared with a building having static façades using whole building energy analysis tool.

title	Facilitating fire and smoke simulation using Building Information Modeling
source	The next city - New technologies and the future of the built environment [16th International Conference CAAD Futures 2015. Sao Paulo, July 8-10, 2015. Electronic Proceedings/ ISBN 978-85-85783-53-2] Sao Paulo, Brazil, July 8-10, 2015, pp. 383.
summary	CFAST is a two-zone model which simulates fire growth and smoke transport. Manually modeling a building using CFAST user interface is a time consuming and error-prone process. In addition, the limitations in CFAST structure impede data transfer between CFAST and BIM (Building Information Modeling). In this research, we identified major limitations of CFAST, proposed solutions to the limitations, and developed a system for data interchange between BIM and CFAST. This greatly facilitated fire and smoke simulation. We further developed a visualization module to visualize the simulation results to overcome the problems when using SmokeView, an application developed by NIST (National Institute of Standards and Technology). A pilot test is conducted using this system. The simulation process was done in just a few minutes. This is expected to help architects to design buildings safer from building fires, and help students in learning building safety and fire related building codes.
