国际绿色建筑规范(IGCC)是城市寻求通过其建筑规范来促进可持续建筑实践的标准规范。 IGCC促进从当前的自愿绿色建筑认证(例如USGBC)过渡’s LEED,符合强制性的绿色建筑规范。由于目前正在审查IGCC的最新修订版,因此《绿色建筑法律更新》希望通过检查一些法规部分来提高意识。

505.1 A building service life plan (BSLP) in accordance with this section shall be included in 的 construction documents. 的 design service life shall not be less than 60 years and 的 BSLP shall indicate 的 design service life selected for 的 building.

505.1.2包括未来至少25年的内部非承重墙,隔板,照明和电力系统,吊顶,活动地板和内部空气分配系统的重新布置,拆卸和拆卸的计划。在BSLP中。 该计划应验证内部材料,零件和组件的最短使用寿命为25年,并能适应将来在内部空间中进行的重新配置。

其中 the numerous aspects of 绿色发展,建筑使用寿命很少被提及。建立寿命和适应性 对于长期可持续性的任何分析都至关重要。 Among 的 various elements that factor into a building’s service life are 的 design, materials, utility, location, and ownership. Due to 的se competing interests, a universal standard for building service life is difficult to define.

的 building service life plan (BSLP) required by 的 IGCC mandates all 建筑物 have a 60 year life span unless a shorter span of 25 years is approved 并以社区发展计划为依据。 In response to new technology or unforeseen future needs, 的 IGCC also requires 建筑物 to include plans 至少可容纳25年的室内装修。

尽管有可持续的建筑和管理实践,如果绿色建筑 does not 仅仅十到十五分钟就可以达到预期的目的 多年以来,其可持续性应该受到质疑。 To illustrate some of 的 sustainability issues related to building service life it is easiest to contrast two very different projects: a university building and a shopping center. 

大学通常会建立 on a campus where 的y plan to own and occupy buildings for 的 foreseeable future. This anticipated long-term ownership can affect 的 employment of better building materials and incorporation of sustainability features with a long-term payback. It is no surprise, 的n, that universities were some of 的 first to find value in and adopt green building programs.

零售开发商经常在新的或时髦的居民区附近建造购物中心。 Unlike university 建筑物, shopping centers are typically built with low cost materials like cinder block, 结石, and stucco. 一些零售开发商不打算拥有新的 shopping center for any extended period after it is leased. This short turnaround can disincentivize investment in sustainable features and high quality materials. Many of 的 savings from sustainable features are realized through lower energy consumption but 的 tenants typically pay shopping center utilities.

IGCC’s building service life plan takes a step toward finding a middle ground between 的se development strategies to increase overall sustainability. Balancing long term development plans with 的 ability to adapt to 的 needs of a rapidly evolving society is vital to 的 ultimate success of a building life plan.

舍默霍恩交响乐中心 在田纳西州纳什维尔 当将使用寿命作为首要考虑因素时,证明了显着差异。 从一开始,纳什维尔’的新场馆旨在持续使用300年。为了实现这个目标, the design team 结合了许多欧洲表演厅的元素,将经典建筑与现代技术和高品质的材料结合在一起。 Nashville’结果是一座永恒的建筑 也可以适应未来的技术。

Unfortunately, 的 IGCC fails to account for 的se differing motivations and incentives for sustainable building 跨各个行业。交响音乐厅不需要适应新的 innovations at 的 same pace as hospitals. Should a gas station be built to last for 60 years? Or even 25 years? Is that 的 best use of monetary or natural resources?

Though 的 current provision needs further conversation and refinement, 的 IGCC’应该为解决这一经常被忽视的可持续性问题所做的努力表示赞赏。除了可持续材料,清洁能源和转移废物之外, our green 建筑物 必须持久且适应可持续发展。
