随着全球城市人口的膨胀,计算我们生活和工作的建筑物的可持续性能就显得十分迫切。但是,现有方法的多样性和复杂性似乎得心应手。这就是ISO 21930:2017发挥作用的地方。

ISO 21930:2017的最新版本 建筑物和土木工程的可持续发展——建筑产品和服务环境产品声明的核心规则,将有助于评估建筑物或基础设施项目的生态友好性,并使用常用的方式来表达环境产品声明(EPD)建筑产品的EPD是一个透明声明,其生命周期的影响有:原料生产、

建造、运行、维护和退役等。这反过来又提供了评估整个建筑物或土木工程对环境的影响所需的资料信息。EPD的关键在于它们可以对建筑产品的环境影响提供透明、独立和可重复的分析,并以可靠的数据和

图形给出详细的信息。作为“可持续发展的通行证”,EPD是设计绿色建筑和其他土木工程的基础。

根据ISO 21930制定的EPD,是一种“绿色建筑”工具,使用公平、公开、科学的评估过程,允许有的材料和产品平等竞争。它将有助于为建筑产品和服务(即大多数建筑材料、地板、窗户,仅举几例)的EPD的方式创造一致性和相容性。

“在建造世界,ISO 21930有能力作出重大贡献,为我们的地球建设一个更具可持续发展的未来,”负责制定新标准的专家团队负责人安妮·罗宁(Anne Roenning)说:“这将大大有助于减少气候变化和其他因建造业和建筑环境而产生的环境影响。”

使用ISO 21930量化建筑物的可持续性具有以下优点:

可比性:确保生成和使用可比较的环境信息,而不会产生技术贸易壁垒。

效率:通过更好地了解产品生产过程中最大影响因素(包括上游和下游的影响),减少“环境足迹”。

可靠性:提供更高的可信度和一定程度的信心,使公众能够在选择和使用建筑产品时使用这些信息进行决策。

ISO 21930适用于建筑产品环境表现信息的提供者和用户,包括建筑行业的设计师、制造商、最终用户、所有者,以及参与EPD方案的人员。这份第二版取代ISO 21930:2007,是根据世界各地不同市场及EDA方案的实际经验而更新的。

ISO 21930:2017是由ISO/TC 5技术委员会建筑和土木工程中的第17分技术委员会建筑和土木工程的可持续性工作小组负责起草,其秘书处设在ISO的法国成员AFNOR。

 

Building a sustainable future with ISO 21930

With urban populations worldwide swelling, there’s an urgent need to calculate the sustainable performance of the buildings that we live and work in. But the variety and complexity of methods available can seem overwhelming. This is where ISO 21930:2017 comes into play.

The latest edition of ISO 21930:2017, Sustainability in buildings and civil engineering works – Core rules for environmental product declarations of construction products and services, will help assess the eco-friendliness of a building or infrastructure projects using a common method for expressing environmental product declarations (EPD).

An EPD for a construction product is a transparent declaration of its life-cycle impact (incorporating raw material production, construction, operation, maintenance and decommissioning). This in turn provides the information needed to assess the environmental impacts of an entire building or civil engineering works. What’s key about EPDs is that they provide a transparent, independent and reproducible analysis of the environmental impacts of construction products and give detailed information with sound data and figures. As a “sustainability passport”, EPDs form the basis for designing green buildings and other civil engineering works.

EPDs developed in accordance with ISO 21930 serve as a “green building” tool using a fair, open and science-based evaluation process that allows all materials and products to compete on a level playing field. It will help create uniformity and consistency in the way environmental product declarations are made for construction products and services (i.e. most building materials, flooring and windows, just to name a few).

“In the world of construction, ISO 21930 has the capacity to make a major contribution to building a more sustainable future for our planet,” says Anne Roenning, leading the team of experts that developed the new standard. “It will significantly contribute to reducing climate change and other environmental impacts attributable to the construction sector and the built environment.”

Quantifying a building’s sustainability using ISO 21930 has the following advantages:

Comparability: Ensure that comparable environmental information is generated and used, without creating technical barriers to trade.

Efficiency: Reduce the “environmental footprint” through a better understanding of the greatest impacts (including those attributable both upstream and downstream) within the chain of processes involved in producing products.

Reliability: Provide increased credibility and a level of confidence that enables the public to use such information for decision making when choosing and using construction products.

ISO 21930 is intended for both providers and users of information related to environmental performance of construction products, including designers, manufacturers, end users and owners in the building and construction sector, as well as those involved in EPD Programmes. This second edition, which replaces ISO 21930:2007, was updated in response to, and to align with, actual experience in the different markets and EPD programmes around the world.

ISO 21930:2017 was developed by ISO technical committee ISO/TC 59, Buildings and civil engineering works, subcommittee SC 17, Sustainability in buildings and civil engineering works, whose secretariat is held by AFNOR, ISO’s member for France.
