Evaluating building performances, such as the indoor daylight, is usually based on numerical simulation and 2D image illustration. It does not take advantage of emerging Augmented Reality (AR) or Mixed Reality (MR) techniques to intuitively aid the building design. The current study probes into the topic bringing building geometry information together with simulation results into AR/MR environments. After introducing some precedent work in the literature, authors recap the typical workflow and report its application on two case studies. The first case study displays the structural simulation of a high-rise building in AR, while the second case study shows the daylight simulation of a two-story house within MR. At last, reflections are conducted and future possibilities are identified. Authors deem that, in the aim of this study, only retrofitting projects are suitable for MR. The present work can help practitioners better understand this new approach, offering the added value of using AR/MR for building design.
Abstract:A fresh urbanism era appears in China with the development of high-speed railway (HSR). Voluminous numbers of local governments are designing and erecting novel cities oriented to the HSR stations with the objective of gaining benefits from the HSR system. Nevertheless, a huge number of these freshly erected districts or cities entail a tremendously high vacancy rate, thereby resulting in 'ghost cities'. The present paper commences with an outline of the China's urban HSR growth and the phenomena of ghost cities. After a literature review on worldwide urban HSR development, the reasons behind the 'ghost city phenomenon' in China are analysed. In the end, the study is concluded by proposing several suggestions for HSR development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
