Thermal performance of cross-laminated timber (CLT) and cross-laminated bamboo and timber (CLBT) panels
ABSTRACT Cross-laminated timber (CLT) is increasingly being utilized in Europe, North America and elsewhere due to its superior mechanical properties and environmental-friendly performance. Considering regions and countries, such as China, those are scarce in structural wood resource but rich in bamboo forest, an idea of introducing bamboo into CLT system has been proposed to form a novel composite material, named as cross-laminated bamboo and timber (CLBT). This paper focuses on the comparison of thermal insulation performance of CLBT and CLT panels. The thermal resistance and transmittance of CLT and CLBT wall specimens were measured by the Guarded Hot Box test. A calculation method provided by ISO standard and a finite element (FE) model were also used to evaluate the thermal resistance of CLT and CLBT panels. Based on the proposed FE model, some parametric analysis was performed through 11 CLBT panels with different compositions, including the layer number of glubam and timber, the thickness of extruded polystyrene and the use of gypsum board and screws. Moreover, the feasibilities of these CLBT panels were evaluated for the application in different climate regions of China and the United States in accordance with the corresponding Chinese and American building energy efficiency standards, respectively. It can be finally concluded that, the development and application of CLBT contributes to achieving the low carbon sustainable features of structures, which is due to the good carbon sequestration ability of its component materials (i.e., timber and bamboo) as well as the good insulation performance of CLBT panels.
期刊介绍:
Informative and accessible, this publication analyses and discusses the integration of the main stages within the process of design and construction and multidisciplinary collaborative working between the different professionals involved. Ideal for practitioners and academics alike, Architectural Engineering and Design Management examines specific topics on architectural technology, engineering design, building performance and building design management to highlight the interfaces between them and bridge the gap between architectural abstraction and engineering practice. Coverage includes: -Integration of architectural and engineering design -Integration of building design and construction -Building design management; planning and co-ordination, information and knowledge management, vale engineering and value management -Collaborative working and collaborative visualisation in building design -Architectural technology -Sustainable architecture -Building thermal, aural, visual and structural performance -Education and architectural engineering This journal is a valuable resource for professionals and academics (teachers, researchers and students) involved in building design and construction, including the following disciplines: -Architecture -Building Engineering -Building Service Engineering -Building Physics -Design Management and Design Coordination -Facilities Management Published papers will report on both fundamental research dealing with theoretical work and applied research dealing with practical issues and industrial innovations. In this way, readers explore the interaction between technical considerations and management issues.
