Increasing number of building owners is adopting vertical greenery system (VGS) as an alternative to building facades or claddings due to its environmental, aesthetic and social benefits in recent years. While numerous studies have been conducted on its potential benefits and its environmental impacts, there has been little focus on its life-cycle cost (LCC) which is a crucial factor for building owners to adopt a VGS as well as to compare among various types of system. To fill this gap, this study aims to identify and calculate the LCC of 3 main types of VGS available in Singapore, where is the tropical climate, namely the carrier, planter and support systems. The cost incurred during each life-cycle stage including initialisation, installation, operation and demolition, are recorded based on 8 completed and ongoing cases selected in Singapore. The analysis of the results shows that the support system has the lowest life-cycle cost (S$885) followed by planter (S$3,786) and then the carrier system (S$4,919). During the life-cycle, the stage of Operations and Maintenance contributed the most to the LCC of a VGS (73.7–83.9%), while plants related parameters, e.g. plant replacement rate and price, affect the largest variances of LCC. for the support system, the LCC of VGS can be balanced off by building energy cost savings within 30 years, but not for other two systems. Suggestions on selecting VGS types, plants and supporting structures to reduce the cost of VGS have been discussed to conclude the study.

“绿化”建筑物的真正成本:热带气候下垂直绿化系统(VGS)的生命周期成本分析

由于近年来的环境,美学和社会效益,越来越多的建筑物所有者正在采用垂直绿化系统(VGS)替代建筑物的外墙或外墙。尽管已经对其潜在好处和环境影响进行了大量研究,但很少关注其生命周期成本(LCC),这是建筑物所有者采用VGS以及在各种类型的VGS中进行比较的关键因素。系统。为了填补这一空白,本研究旨在确定和计算新加坡的三种主要VGS的LCC,新加坡是热带气候,即承运人,种植者和支持系统。每个生命周期阶段的成本,包括初始化,安装,操作和拆除,均根据在新加坡选择的8个已完成和进行中的案例进行记录。对结果的分析表明,支持系统的生命周期成本最低(885新元),其次是播种机(3,786新元),其次是运输系统(4,919新元)。在生命周期中,操作和维护阶段对VCC的LCC贡献最大(73.7–83.9%),而与工厂相关的参数(例如工厂更换率和价格)影响LCC的最大差异。对于支持系统,可以通过在30年内节省建筑物的能源成本来平衡VGS的LCC,但对于其他两个系统则不能。总结了有关选择VGS类型,工厂和支撑结构以降低VGS成本的建议,以完成研究。运营和维护阶段对VGS的LCC贡献最大(73.7–83.9%),而与工厂相关的参数(例如工厂更换率和价格)影响LCC的最大差异。对于支持系统,可以通过在30年内节省建筑物的能源成本来平衡VGS的LCC,但对于其他两个系统则不能。总结了有关选择VGS类型,工厂和支撑结构以降低VGS成本的建议,以完成研究。运营和维护阶段对VGS的LCC贡献最大(73.7–83.9%),而与工厂相关的参数(例如工厂更换率和价格)影响LCC的最大差异。对于支持系统,可以通过在30年内节省建筑物的能源成本来平衡VGS的LCC,但对于其他两个系统则不能。总结了有关选择VGS类型,工厂和支撑结构以降低VGS成本的建议,以完成研究。
