walking distance


the distance that a pedestrian must travel between origins and destinations without obstruction, in a safe and comfortable environment on a continuous network of sidewalks, all weather-surface footpaths, crosswalks, or equivalent pedestrian facilities. The walking distance must be drawn from an entrance that is accessible to all building users.

歩行者が出発地から目的地までを、歩道、全天候対応路面の歩路、横断歩道、または同等の歩行施設の連続ネットワークにて安全で快適に障害なく移動できる距離。 歩行距離は、建物の全利用者がアクセス可能な出入口から計測しなければならない。

waste diversion


a management activity that disposes of waste through methods other than incineration or landfilling. Examples include reuse and recycling.

焼却または埋め立て以外の方法で廃棄物を処理する管理活動。 例としては、再利用やリサイクルが含まれる。



the conversion of nonrecyclable waste materials into usable heat, electricity, or fuel through a variety of processes, including combustion, gasification, pyrolization, anaerobic digestion, and landfill gas (LFG) recovery


water body


the surface water of a stream (first-order and higher, including intermittent streams), arroyo, river, canal, lake, estuary, bay, or ocean. It does not include irrigation ditches.

川(河道位数1以上、間欠河流も含む)、アロヨ地形(涸れ川の小峡谷)、河川、運河、湖、河口、湾、海洋の水面。 これには灌漑水路は含まない。

water budget


a project-specific method of calculating the amount of water required by the building and associated grounds. The budget takes into account indoor, outdoor, process, and makeup water demands and any on site supply including estimated rainfall. Water budgets must be associated with a specified amount of time, such as a week, month, or year and a quantity of water such as kGal, or liters.


wet meter


a device installed inside a water pipe to record the volume of passing water




an area that is inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances does support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas, but exclude irrigation ditches unless delineated as part of an adjacent wetland.




plant-based materials that are eligible for certification under the Forest Stewardship Council. Examples include bamboo and palm (monocots) as well as hardwoods (angiosperms) and softwoods (gymnosperms)

FSC(森林管理協議会)の認証取得可能な植物系素材。 例として広葉樹(被子植物)、針葉樹(裸子植物)のみならず竹やヤシ(単子葉植物)なども挙げられる。
