The building industry has traditionally been driven by cost and time metrics while meeting quality and safety requirements. However, environmental concerns such as the carbon effect of the final product receive less attention. Due to increasing emissions awareness within the society, there have been calls from the public for greater environmental and social accountability. While many client organizations seek to add environmental measures to their tender selection criteria, efforts to reduce carbon emissions in the building construction are not well understood. This paper proposes that by selecting appropriate structural parameters and building sites, the construction of buildings will be in accordance with a low carbon footprint intensity (CFI). This is demonstrated by the analysis of various factories producing structural materials, along with a wide range of residential buildings. It was found that through the replacement of steel structures with concrete structures, a 24.46% decrease (69.97 kg/m²) in the CFI of structures will be achieved. It was also found that replacing an eight-story steel structure with two different four-story structures will result in a 35.94% (127.82 kg/m²) reduction in carbon intensity. In addition, a 14.44% (47.64 kg/m²) reduction in the CFI of a steel structure located in a site with stiff soil was observed by relocating it to a very dense soil site. This figure for a concrete structure was 13.94% (34.87 kg/m²). It is hoped that project managers and client organizations find the results of this research useful when deciding on structural parameters with lower carbon emissions. In this way, the paper contributes to the current performance of sustainable buildings.

建筑行业历来受成本和时间指标驱动，同时满足质量和安全要求。然而，诸如最终产品的碳效应等环境问题受到的关注较少。由于社会对排放的认识不断提高，公众呼吁加强环境和社会责任。虽然许多客户组织寻求将环境措施添加到他们的投标选择标准中，但人们对减少建筑施工中碳排放的努力还不是很了解。本文提出，通过选择合适的结构参数和建筑场地，建筑物的建造将符合低碳足迹强度（CFI）。对生产结构材料的各个工厂的分析证明了这一点，以及各种各样的住宅建筑。结果表明，通过用混凝土结构替代钢结构，减少了 24.46%（69.97 kg/m² ) 在 CFI 的结构中将实现。还发现用两个不同的四层结构代替八层钢结构将导致碳强度降低35.94% (127.82 kg/m ² )。此外，通过将钢结构重新安置到非常密集的土壤场地，观察到位于坚硬土壤场地的钢结构的 CFI 降低了 14.44% (47.64 kg/m ² )。混凝土结构的这个数字是 13.94% (34.87 kg/m ² )。希望项目经理和客户组织在决定具有较低碳排放的结构参数时发现这项研究的结果很有用。通过这种方式，本文有助于可持续建筑的当前性能。
