Abstract

ABSTRACT The affordability of sustainable building remains a significant challenge; developers, building owners, and design teams often point to high construction costs as the primary obstacle hindering the uptake of sustainable building. Because of a lack of clarity, empirical studies and evidence supporting the claim of sustainable building as expensive are inadequate, thus the perceived high cost of sustainable building is still debatable. This study has a three-pronged approach: (1) to collect actual construction costs of certified sustainable buildings, (2) to take a deep dive into construction cost using empirical data and analyze the correlation between the level of sustainability and the construction cost, and (3) to examine the influence of cost components on the total construction cost. Data from 72 LEED buildings was collected and included in the analysis. The findings show the following: (a) the construction costs of the studied sustainable buildings are comparable to those of conventional buildings (even lower); (b) the correlation between the level of sustainability and the construction cost is inconclusive; and (c) soft costs, especially the design cost, have a similar level of influence on the total construction cost as those of hard costs.

可持续发展成本高吗?来自已建成项目的经验证据

可持续建筑的可负担性仍然是一个重大挑战;开发商、业主和设计团队经常指出，高昂的建筑成本是阻碍可持续建筑发展的主要障碍。由于缺乏明确性，支持可持续建筑昂贵主张的实证研究和证据不足，因此可持续建筑的高成本感知仍然存在争议。本研究采用三管齐下的方法:(1)收集获得可持续建筑认证的实际建筑成本;(2)利用实证数据深入研究建筑成本，分析可持续性水平与建筑成本之间的相关性;(3)考察成本构成对总建筑成本的影响。收集了72座LEED建筑的数据并将其纳入分析。研究结果显示:(a)可持续建筑的建造成本与传统建筑相当(甚至更低);(b)可持续性水平与建筑成本之间的相关性尚无定论;(3)软成本尤其是设计成本对总造价的影响程度与硬成本相当。

期刊介绍： The purpose of the Journal of Green Building is to present the very best peer-reviewed research in green building design, construction, engineering, technological innovation, facilities management, building information modeling, and community and urban planning. The Research section of the Journal of Green Building publishes peer-reviewed articles in the fields of engineering, architecture, construction, construction management, building science, facilities management, landscape architecture, interior design, urban and community planning, and all disciplines related to the built environment. In addition, the Journal of Green Building offers the following sections: Industry Corner that offers applied articles of successfully completed sustainable buildings and landscapes; New Directions in Teaching and Research that offers guidance from teachers and researchers on incorporating innovative sustainable learning into the curriculum or the likely directions of future research; and Campus Sustainability that offers articles from programs dedicated to greening the university campus.
