My Wooden House: Unit Cost of Popular Housing in Acre state, Brazil

ABSTRACT Housing deficit is a problem that affects low-income populations in Brazil, with over 6 million families affected nationwide and approximately 631 thousand in the North region of the country. Ordinance no. 318/2014 of the Brazilian Ministry of Cities authorized the construction of popular housing using timber as raw material in that region. The objective of this study was to establish the unit cost of a wooden dwelling, referenced in the project Popular Wooden Housing (PWH) developed by the Laboratory of Forest Products and the University of Brasília (UNB) for the National Rural Housing Program (NRHP). The Basic Unit Cost (BUC/m2 ) methodology was used, with collection of prices in Rio Branco, capital of the state of Acre, for composition of the Final Unit Cost (FCU/m2) of a wood construction. Mean cost of R$ 934.52/m2 was observed from September 2015 to April 2016. Feasibility of wood construction was demonstrated by a final cost per m2 28.06% lower than that of a conventional masonry house.

**摘要** 住房短缺是困扰巴西低收入群体的突出民生问题，全国范围内受影响家庭逾600万户，该国北部地区受影响家庭约63.1万户。巴西城市部第318/2014号法令授权在该地区以木材为原料建设保障性住房。本研究旨在确定木制住宅的单位造价，其参考依据为林产品实验室与巴西利亚大学（University of Brasília, UNB）为国家农村住房计划（National Rural Housing Program, NRHP）开发的大众木制住房（Popular Wooden Housing, PWH）项目。研究采用基本单位造价（Basic Unit Cost, BUC/m²）方法，通过收集阿克里州首府里奥布兰科的建材价格，核算得到木结构建筑的最终单位造价（Final Unit Cost, FCU/m²）。2015年9月至2016年4月期间，测算得到的平均造价为每平方米934.52巴西雷亚尔。相较于传统砖石结构住宅，木结构建筑的最终单位造价低28.06%，由此证实了木结构建筑的可行性。
