尽管在节能和弹性建筑设计战略的成本评估方面做出了孤立的努力，但仍然需要进行综合评估，纳入建筑物整个生命周期的主要预期成本，以进行更全面的成本效益分析。本文的主要目标是扩大范围的成本效益估计的住宅建筑，通过分析的预期成本的损害，由于自然灾害的背景下，其他生命周期成本。具体来说，这里提出的生命周期成本分析包括由于地震和飓风危害以及能源消耗，除了初始建设，日常维护和家庭装修的预期维修成本。一个案例研究，提出了一个单户，木结构住宅建筑在两个层次的防灾设计。根据决策相关的经济措施，估计总体预期生命周期成本。在不同的情况下的案例研究的方法的应用产生了一些有趣的见解比较成本分析的敏感性，不同的情况下，有关的位置，未来的价值和经济措施的比较。(C)2017年美国土木工程师协会。
Despite isolated efforts in the cost assessment of design strategies for energy-efficient and resilient buildings, there is still a need for an integrated assessment that incorporates major expected costs over the entire lifecycle of the building for more comprehensive cost-benefit analysis. The main goal of this paper is to broaden the scope of cost-effectiveness estimates for residential buildings by analyzing the expected costs of damage due to natural hazards in the context of other lifecycle costs. Specifically, the lifecycle cost analysis presented here includes the expected cost of repair due to earthquake and hurricane hazards as well as the energy consumption, in addition to the initial construction, routine maintenance, and home improvement. A case study is presented for a single-family, wood-frame residential building at two levels of hazard-resistant design. The overall expected lifecycle cost is estimated in terms of decision-relevant economic measures. The application of the approach to the case study under different scenarios produces some interesting insights about the sensitivity of the comparative cost analysis to different scenarios regarding the locations, future values, and economic measure of comparison.
