帮助启动设想基础设施可持续性评级工具四年（新利18备用ENR 2015年6月17日),一个哈佛大学设计研究生院program has published a guidebook for municipalities in how to take an integrated approach to designing and building sustainable infrastructure in concert with urban planning.

虽然Envision允许公共部门基础设施所有者衡量桥梁，隧道，水或能源系统等单个项目的长期可持续性，但新指南，标题为“新利18备用网址“Planning Sustainable Cities: An Infrastructure Based Approach,”提供将这些单个项目编织到无缝且可持续的网络中的工具。新利18备用网址

上周由大学发行Zofnass可持续基础设施计划这本书着重于基础设施系统的性能以及如何利用建筑物和其他资产之间的协同作用，以最大程度地减少对基础设施的需求。

By minimizing demand on resources, an integrated infrastructure system is less expensive because it requires construction of fewer treatment plants, for example. A green infrastructure approach also reduces the need for sewers since it decreases storm water runoff.

哈佛指南包括由著名建筑行业专业人士撰写的几篇论文由Zofnass计划的大学设计与技术教授Spiro N. Pollalis编辑和执导。Pollalis说：“可持续的城市应该具有可持续的基础设施，可持续的基础设施应与城市的规划并驾齐驱。”

轮询alis also said urban planners shouldn’t “make decisions based on a single infrastructure project or a single infrastructure system, but look at multiple objectives at the same time.”

这本书的撰稿人，CH2M Hill的副总裁兼副总裁兼副总监Erin Mosley在学校的11月3日和第4届会议上表示，它不仅为指南提供了建议和方法，并提供了建议和方法。官员们，这也为他们提供了将这些想法出售给选民的“信心”。她说：“然后，当他们推荐这一点时，他们可以参考哈佛大学和Zofnass计划。”“它具有信誉。它有助于创建对话和对话的空间。”

特里·贝内特·奥特德斯克（Terry Bennett Autodesk）民事基础设施高级行业策略师该指南可帮助城市规划师超越自己的培训和经验，以考虑替代解决方案。贝内特说：“这不是关于如何做的一系列处方，而是问您的问题，使您可以对这种方法进行不同的思考。”“‘我们应该考虑吗？如果我们想考虑这一点，那么下一个级别是什么？因此，它有助于引导您解决问题，以获取您需要做不同的答案。”

Bennett said when a new piece of infrastructure is being built, planners should think about how it will be repurposed at the end of its lifecycle, pointing to projects such as New York City’s High Line, which was erected on abandoned rail lines or the 11th Street Bridge Park in Washington, D.C that would be built atop four piers left behind when the bridge was replaced.

贝内特说：“如果您开始了解预期寿命的时间，并计划您想要的东西之后，您可以计划一些功能，以便在没有全新的努力的情况下很容易重新使用。”“这本书是这些类型的思考过程，可以帮助您完成。”

Envisioning the future

Zofnass计划成立于2007年，在与三个工程协会：美国土木工程师学会，美国公共工程协会和美国工程委员会cos。managed and quasi-commercialized by the可持续基础设施研究所- 建筑物超出建筑物的项目可持续性2012年推出。

工具利率基础架构项目新利18备用网址五类：生活质量，领导力，自然世界，资源分配以及气候和风险。基于资源使用，运营弹性，生态系统修复，生命周期成本和投资回报率的项目授予了6新利18备用网址0个可能的学分。新利18备用官网登录该计划提供了四个项目评分：铜，银，金和白金。

轮询alis said 5,000 people worldwide now are credentialed in the Envision approach while 24 projects have achieved Envision certification in the U.S., with 19 more in the process. He also said Envision is being used on projects in Italy, Germany, Iran, Malaysia, Pakistan and Saudi Arabia.

设计部门管理顾问Paul Zofnass说，这本长达356页的指南是Envision评级工具的扩展，但也将评级系统提升到了新的水平。the book offers the first comprehensive approach to measuring sustainability as it applies to an entire city.

“It needs to be because building a city is just not one building,” he said. “It’s a community of living people and it’s going to have a big impact on the environment around it.”

Common ground

The Harvard conference, which had about 450 people registrants, included panel discussions on sustainability in key infrastructure sectors and how to make the “business case” for sustainable infrastructure.

到那时，帕拉利斯认为，考虑生命周期成本时，可持续项目通常便宜。新利18备用网址新利18备用官网登录他说：“某些可持续性元素很昂贵，但大多数不是。”

会议还探讨了如何使用信息技术和大数据来改善每个基础架构。莫斯利说，她与客户谈论数字基础设施的对话在她询问他们最需要修复的基础架构之前就开始广泛地开始。

“You need to have the vision but then you start with one particular place that is your biggest pain point and you can grow it from there,” Mosley said. “But you don’t want to start with a pain point without a vision. That’s where the planning guidelines come in; you understand how that piece can fit into the whole picture and you are able to move more fluidly between things.”
