【 摘 要 】

Bamboo scrimber was fiber based panel developed in 2000s that was potential to be an ideal substitute for construction timber in bamboo growing areas. For evaluating the performance of applying bamboo scrimber in building envelope by clarifying the performance difference with timber, softwood (SW) and hardwood (HW) units were set as reference model, accordingly bamboo scrimber (BFB) units of the same construction and space size as evaluation model, by which performance regarding to building component and space unit were compared. Space units enclosed with bamboo, softwood and hardwood exterior walls were constructed and simulated in WUFI Plus for 16 cities from tropical and humid subtropical regions overlapped with the bamboo forest distribution. Bamboo scrimber showed changeable strengths of heat storage and vapor resistance and weakness of heat transport properties, which varied with the external climate, building function, construction type and HVAC condition.
