“…Recently, BIM has been used to improve building disaster management by understanding physical and functional characteristics of objects and visualizing building spatial information in three dimensions [25,26]. However, effective fire emergency methods should rely on the real-time and dynamic information [11].…”

-The increasing complexity of buildings has brought some difficulties for emergency response. When fires occur in a building, limited perception regarding the disaster area and occupants can increase the probability of injuries and damages. Thus, the availability of comprehensive and timely information may help understand the existing conditions and plan an efficient evacuation. For this purpose, Building Information Modeling (BIM) should be integrated with three sets of information: (1) occupancy that defines the type of space usage; (2) occupants' information; and (3) sensory data. The Industry Foundation Classes (IFC), as a standard of BIM, has the definitions for all areas, volumes, and elements of a building. IFC also has the basic definitions of sensor and occupant entities. However, these entities do not provide enough dynamic and accurate information for supporting emergency management systems. This paper aims to extend IFC for fire emergency real-time management using sensors and occupants' information. The specific objectives of this paper are: (1) extending IfcSensor entity for occupant's sensors; (2) adding new attributes to IfcOccupant to support emergency response operations and defining a new entity for occupancy; and (3) defining the relationships between sensors, occupants, occupancy, time series, and building components in the context of building evacuation. The feasibility of the proposed method is discussed using a case study.

“…Suarez et al [11] use Google Glass so that learners can make instant inquiries with handsfree interaction (voice interaction). In disaster education, Wang et al [12] developed a 3D-simulator that allows HMD wearers to evacuate from a virtual building fire. We developed evacuation drill systems using AR and HMDs [13][14] [15].…”

Abstract-Disaster education focusing on how we should take immediate actions after disasters strike is essential to protect our lives. However, children find it difficult to understand such disaster education. Instead of disaster education to children, adults should properly instruct them to take immediate actions in the event of a disaster. We refer to such adults as Immediate-Action Commanders (IACers) and attach importance to technology-enhanced IACer training programs with high situational and audio-visual realities. To realize such programs, we focused on digital game, augmented reality (AR) and headmounted displays (HMDs). We prototyped three AR systems that superimpose interactive virtual objects onto HMDs' real-time vision or a trainee's actual view based on interactive fictional scenarios. In addition, the systems are designed to realize voice-based interactions between the virtual objects (i.e., virtual children) and the trainee. According to a brief comparative survey, the AR system equipped with a smartphone-based binocular opaque HMD (Google Cardboard) has the most promising practical system for technology-enhanced IACer training programs.

“…Therefore, both CityGM L and IndoorGM L in GIS field cannot meet the requirement of data environment. In construction industry, Industry Foundation Classes (IFC) and Building Information M odel (BIM ) has been applied in building fire research also (Spearpoint, 2007;Dimyadi, 2008;Wang, 2014). However, IFC model was focuses on the information representation of architectural components, and the indoor space division was lacked, which is inadequate for building fire scene modelling also.…”

ABS TRACT:Building fire is a risky activity that can lead to disaster and massive destruction. The management and disposal of building fire has always attracted much interest from researchers. Integrated Virtual Geographic Environment (VGE) is a good choice for building fire safety management and emergency decisions, in which a more real and rich fire process can be computed and obtained dynamically, and the results of fire simulations and analyses can be much more accurate as well. To modelling building fire scene with VGE, the application requirements and modelling objective of building fire scene were analysed in this paper. Then, the four core elements of modelling building fire scene (the building space environment, the fire event, the indoor Fire Extinguishing System (FES) and the indoor crowd) were implemented, and the relationship between the elements was discussed also. Finally, with the theory and framework of VGE, the technology of building fire scene system with VGE was designed within the data environment, the model environment, the expression environment, and the collaborative environment as well. The functions and key techniques in each environment are also analysed, which may provide a reference for further development and other research on VGE.
