ABSTRACT

This article explores how heritage values can be productively sustained or transformed by processes of building deconstruction and materials reuse, which address the increasing magnitude of demolition waste, landfill and resource use in urban development. The article starts by examining literature in heritage studies, sustainable building, and discard studies, then presents two examples from Vancouver, a Canadian city under intense development pressure, to help frame questions from project and policy contexts. Building on these questions, it reviews the relationship between heritage values and waste, gaps in deconstruction and salvage policies, the classifications of materials in deconstruction and reuse, and possible expanded uses for heritage inventories. In the Anthropocene, merely conserving designated buildings, or salvaging character-defining elements associated with heritage values, is not only inadequate, it helps to define waste, or that which does not have value. An ethic of conservation is called for that makes place for deconstruction as an acceptable reuse strategy while addressing the fate of all existing buildings and materials.

摘要

本文探讨了如何通过建筑解构和材料再利用的过程来有效地维持或改变遗产价值，这些过程解决了城市发展中越来越多的拆除废物，垃圾填埋场和资源利用问题。本文首先考察了遗产研究，可持续建筑和废弃研究方面的文献，然后提出了来自加拿大温哥华的两个例子。温哥华是一个面临巨大发展压力的城市，以帮助从项目和政策环境中提出问题。在这些问题的基础上，它回顾了遗产价值与废物之间的关系，破坏性建筑和救助政策中的差距，破坏性建筑和再利用中的材料分类以及遗产清单的可能扩展用途。在人类世时期，仅保存指定的建筑物，或挽救与遗产价值相关的角色定义元素，不仅不充分，而且有助于定义浪费或没有价值的元素。需要一种保护伦理，即在解决所有现有建筑物和材料的命运的同时，将销毁作为一种可以接受的重用策略。
