Abstract: Structural Insulated Panels (SIPs) are high performance load-bearing panels, which are considered to be the next generation construction material. Based on the results of the previous studies on SIP building, combined with the theory of life-cycle assessment, this paper constructs a dual-index evaluation model of economical efficiency and carbon emission in life cycle. By adopting the data of previous research, comparisons were conducted between SIP building and traditional masonry-concrete house, which suggests significant advantages of SIP building. The results implicate that SIPs would have extensive popularization potential in the process of development of low-carbon buildings.

Abstract: An experimental study was carried out to examine the material and structural properties of a new type of structural insulated panel (SIP) comprising the plywood board as facial panels and the Styrofoam as the core material. Material properties were characterized by subjecting specimens to bending, compression, tension and double shear tests. SIP specimens, both in small-scale and prototype sizes, were tested under bending, racking and axial loads respectively. This paper will report these tests and the obtained results.

Abstract: The cladding industry has been experiencing a rapid development since two decades ago. The client’s requirements and architect’s ambition make the building cladding become more complex than ever before. The technical complexity calls for more comprehensive managerial techniques, especially information management. This paper proposes a web-based information management system, in which software package was developed and hardware incorporated. After establishing the framework initially, a main challenge, information sources, of this mechanism was discussed.

Abstract: The increasing complexity of the cladding procurement and fragmentation of the supply chain bring challenges for communication and making informed decisions. Based on the study on cladding design and procurement process, this paper identifies the flows existing in the cladding supply chain and patterns of communication between the parties involved. The results of the research provide the foundation for further innovation on effective and secure approaches to information exchange and collaborative decision making.

Abstract: Glass is widely used for its properties of transparency. It has been favoured by architects for the last two decades and used to deliver a distinct style of architecture. However, the conflicting performance requirements make the decision making on glass selection in building envelopes a complex process. This paper investigates the factors affecting the selection of glass used in building facade, and proposes a hierarchy of decision making to facilitate the information flow. This may provide an integrated and robust approach to reach an informed decision.

Abstract: In China, the construction industry has been developing rapidly over the past decades, at the same time, generating a huge amount of construction and demolition waste (CDW). The stream of CDW must be dealt with special attention, at least because of the shortage of landfill space for disposal and the need of sustainable development. This paper presents solutions to manage and control major type of building CDW in a technically feasible and economically efficient manner, with an example of Xi’an City. Recommendations are made in order to promote sustainable CDW management in practice.
