MR Credit 5: Regional Materials
1–2 Points

Intent
To increase demand for building materials and products that are extracted and manufactured within the region,
thereby supporting the use of indigenous resources and reducing the environmental impacts resulting from
transportation.

Requirements
Use building materials or products that have been extracted, harvested or recovered, as well as manufactured,
within 500 miles of the project site for a minimum of 10% or 20%, based on cost, of the total materials value. If only
a fraction of a product or material is extracted, harvested, or recovered and manufactured locally, then only that
percentage (by weight) can contribute to the regional value. The minimum percentage regional materials for each
point threshold is as follows:
Regional Materials; Points
10% 1
20% 2
Mechanical, electrical and plumbing components and specialty items such as elevators and equipment must not be
included in this calculation. Include only materials permanently installed in the project. Furniture may be included if
it is included consistently in MR Credit 3: Materials Reuse through MR Credit 7: Certified Wood.

Potential Technologies & Strategies
Establish a project goal for locally sourced materials, and identify materials and material suppliers that can
achieve this goal. During construction, ensure that the specified local materials are installed, and quantify the total
percentage of local materials installed. Consider a range of environmental, economic and performance attributes
when selecting products and materials.

MR C5: 地方材料
1–2分

目的
建筑材料和制品中，增加使用本地原料、加工产品市场开发，支持地方材料使用，减少材料运
输产生的环境影响。

要求
工程材料和制品中，所产自、来源、翻新、加工于500英里(804公里)范围内的地方材料，其价
值应至少占工程材料总价值的10%或20%。如果材料中只是某成分源自、加工、翻新于本地，则
只有这些成分按其比例可以贡献于本得分计算，计算方法以其成分的重量比例乘以材料或产品
的总价值计算其价值。最低的地方材比例与得分标准如下：
地方材比例;得分
10% 1
20% 2
机械、电气设备、水管、管件或其它如电梯等专用设备，不能被计入材料回用计算。只有永久
性安装在建筑中的家俱才能被计入，但需与在项目MRC3到MRC7中保持一致。

技术措施和策略
建立工程地方材料目标，确定材料供应商，施工中确保这些材料得以按确定的比例使用，考虑其性
能、经验等要素，选择适用的材料和产品范围。
