Decisions made in the design of urban developments at the neighbourhood scale influence damages on human health, which depend on location. So far, no standard has proposed the range of health damage coming from neighborhoods located in any region, due to the different morphologies of neighborhoods, and limited study numbers. Aware of this fact, this study was conducted with the aim to evaluate and to compare the effect of health damage produced by a sustainable neighborhood in which the same morphology was designed in several regions. To perform this comparison, the same neighborhood design is applied to 150 countries, but four parameters are adapted to each country: energy mix, local climate, building materials, and occupants ‘mobility. In addition, this study analysis the induced health impact of the neighborhood over a life cycle of 100 years and examines the impact of mobility and renewable energy on the health, which was evaluated by Pleiades ACV software. Among the four local parameters (energy mix, local materials, climate, and transport), the energy mix has the most significant effect on the health damage. The results show that the countries having a lower concentration of renewable energy sources have higher health damage than others. Africa is the continent that most affected by health damage due to lack of having an eco-neighborhood. The building materials and electricity use are the main sources of health damage in a neighborhood. The implementation of photovoltaic panels on the roofs of an eco-neighborhood has a significant impact on the potential health damages. Among the different stages of the neighborhood life cycle, the operation stage is the most significant which is responsible over 50% of total health damage. It is important to multiply ecological neighborhoods around the world, because health damage is estimated to be 20% lower in sustainable neighborhoods than more conventional neighborhoods.

对来自 150 个国家/地区的居民区造成的健康损害的环境分析

在邻里尺度的城市发展设计中做出的决定会影响对人类健康的损害,这取决于位置。由于街区形态不同,研究数量有限,目前还没有标准提出任何地区的街区对健康的损害范围。意识到这一事实,进行这项研究的目的是评估和比较可持续社区所产生的健康损害的影响,在该社区中,在多个区域设计了相同的形态。为了进行这种比较,将相同的社区设计应用于 150 个国家/地区,但四个参数适用于每个国家/地区:能源组合、当地气候、建筑材料和居住者的流动性。此外,这项研究分析了社区在 100 年的生命周期中对健康的影响,并检查了流动性和可再生能源对健康的影响,这些影响由 Pleiades ACV 软件进行了评估。在四个局部参数(能源结构、当地材料、气候和交通)中,能源结构对健康损害的影响最为显着。结果表明,可再生能源集中度较低的国家对健康的损害高于其他国家。由于缺乏生态社区,非洲是受健康损害影响最大的大陆。建筑材料和电力使用是社区健康损害的主要来源。在生态社区的屋顶上安装光伏电池板对潜在的健康损害具有重大影响。在社区生命周期的不同阶段中,运营阶段最为重要,占总健康损害的50%以上。在世界各地增加生态社区非常重要,因为据估计,可持续社区对健康的损害比传统社区低 20%。
