This study examines variability in material use in single-family dwellings within and between three different locations (Toronto, Perth, and Luzon). It investigates how the use of different functional units changes the perception of what buildings are more materially efficient and which location has the more materially efficient home building norms. Material intensities for 80 single- family dwellings in the three locations form the foundational data for the paper. Important variabilities exist in the material intensities of the single-family dwellings and change with the functional unit selected (e.g., 7–23% for 1 m2 functional unit). Toronto single-family dwellings appear to be one of the least material intensive when presented per 1 m2 floor area but become the most material intensive when presented per 1 building and 1 bedroom with the opposite for Luzon. Housing size is the most effective explainer of overall material use with foundations and walls consuming the most materials but in different ratios across the three locations.

单户住宅的材料强度:多伦多、珀斯和吕宋岛的地点、功能单元和材料使用驱动因素之间的差异

本研究考察了三个不同地点(多伦多、珀斯和吕宋)内部和之间的单户住宅材料使用的变化。它研究了不同功能单元的使用如何改变人们对哪些建筑物的物质效率更高以及哪个位置具有更物质效率的住宅建筑规范的看法。三个地点的 80 套独户住宅的物质强度构成了本文的基础数据。独户住宅的材料强度存在重要的变化,并随着所选的功能单元而变化(例如,1 m 2功能单元的7-23%)。多伦多单户住宅似乎是每 1 m 2材料密集度最低的住宅之一建筑面积,但在每 1 栋建筑和 1 间卧室呈现时成为材料密集度最高的建筑,而吕宋岛则相反。房屋大小是整体材料使用的最有效解释因素,地基和墙壁消耗的材料最多,但三个位置的比例不同。
