title	A New Implementation of Head-Coupled Perspective for Virtual Architecture
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	Optimo: A BIM-based Multi-Objective Optimization Tool Utilizing Visual Programming for High Performance Building Design

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	Parametric BIM-based Energy Simulation for Buildings with Complex Kinetic Façades
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	Creating and Improving a Closed Loop: Design Optimization and Knowledge Discovery in Architecture
source	International Journal of Architectural Computing vol. 13 - no. 2, 123-142
summary	This paper presents computational methods for creating and improving a closed loop of design optimization and knowledge discovery in architecture. It first introduces a design knowledge-assisted optimization improvement method with the technique - offline simulation - to reduce the computing time and improve the efficiency of the design optimization process utilizing architectural domain knowledge. It then describes a new design knowledge discovery system where design knowledge can be discovered from optimization through an automatic data mining approach. The discovered knowledge has the potential to further help improve the efficiency of the optimization method, thus forming a closed loop of improving optimization and knowledge discovery. The demonstration and validation of both methods are presented in the context of a case study with parametric form-finding for a nursing unit design with two design objectives: minimizing the nurses’ travel distance and maximizing daylighting performance in patient rooms.

title	A User Interface for Parametric Architectural Design Reviews
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. 65-74
doi	https://doi.org/10.52842/conf.caadria.2015.065
summary	Architectural form and performance are affected by the designer's graphical representation methods. Parametric CAD systems, as design and representation tools, have become ubiquitous in architectural practice and education. Literature in the area of parametric design reviews is scarce and focused within building inspection and construction coordination domains. Additionally, platforms marketed as design review tools lack basic functionality for conducting comprehensive, parametric, and performance-based reviews. We have developed a user interface prototype where geometric and non-geometric information of a Building Information Model were translated into an interactive gaming environment. The interface allows simultaneous occupation and simulation of spatial geometry, enabling the user to engage with object parameters, as well as, performance-based, perspectival, diagrammatic, and orthographic representations for total spatial and performance comprehension.

title	A BIM-compatible schema for architectural programming information
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. 380.
summary	Architectural programming, although a key part of AECFM processes, has not been well integrated into Building Information Modeling (BIM). Having access to architectural programming information throughout the lifecycle of a building can add value to design evaluation, facility management, renovation and extension. There is not currently a comprehensive and standard data model to store architectural programming information. Our research is producing a universal format for an architectural program of requirements (UFPOR) that can connect the architectural programming information to the IFC BIM schema. The result is a data model for architectural programming that is inherently interoperable with BIM standard schema. A graphical user interface facilitates data creation and manipulation. The schema and effectiveness of the bridging fields has been tested by entering the content of three two different architectural programming documents into the UFPOR database.
