Glossary LEED V4(p)

patient position


a patient bed, infusion chair, recovery room bay, or other location where a patient receives clinical care


peak demand


the maximum electricity load at a specific point in time or over a period of time


peak watering month


the month with the greatest deficit between evapotranspiration and rainfall. This is the month when the plants in the site’s region potentially require the most supplemental water typically a mid-summer month. (Sustainable Sites Initiative)

蒸発散量に対し降雨量が最も不足する月。敷地の地域の植物が、潜在的に最大の灌水量となる月で、一般的に真夏の月。(Sustainable Sites Initiative)

permanent interior obstruction


a structure that cannot be moved by the user without tools or assistance from special trades and facilities management. Examples include lab hoods, fixed partitions, demountable opaque full- or partial-height partitions, some displays, and equipment.

道具または専門業者や施設管理部門の補助なしでは使用者が移動できない構造物。 実験用フード、固定間仕切、完全または部分的な高さの可動間仕切、一部の展示物や機器などが含まれる。

permanent peak load shifting


the transfer of energy consumption to off-peak hours, when demand for power is lower and energy is therefore less expensive


permeable pavement


a paved surface that allows water runoff to infiltrate into the ground


persistent bioaccumulative toxic chemical


a substance that poses a long-term risk to both humans and the environment because it remains in the environment for long periods, increases in concentration as it moves up the food chain, and can travel far from the source of contamination. Often these substances can become more potent and harmful to ecosystems the longer they persist. See U.S. EPA’s website on persistent bioaccumulative toxic chemicals,


place of respite


an area that connects healthcare patients, visitors, and staff to health benefits of the natural environment. (Adapted from Green Guide for Health Care Places of Respite Technical Brief)

ヘルスケア施設の患者、訪問者とスタッフに対して自然環境による健康的価値を与えるエリア。 (医療福祉施設の場所のためのグリーンガイド、レスパイト・プレイスの技術的概要(Green Guide for Health Care Places of Respite Technical Brief)より)

plug load or receptacle load


the electrical current drawn by all equipment that is connected to the electrical system via a wall outlet.


postconsumer recycled content


waste generated by households or commercial, industrial and institutional facilities in their role as end users of a product that can no longer be used for its intended purpose

家庭または 、業務用施設(商業、工業、企業など)から、製品のエンドユーザーとして使用された後に排出される廃棄物で、もはや意図した目的では使用できない状態となったもの

potable water


water that meets or exceeds U.S. Environmental Protection Agency drinking water quality standards (or a local equivalent outside the U.S.) and is approved for human consumption by the state or local authorities having jurisdiction; it may be supplied from wells or municipal water systems


power distribution unit output


the electrical power from a device that allocates power to and serves information technology (IT) equipment. Power distribution unit (PDU) output does not include efficiency losses of any transformation that occurs within the PDU, but it can include downstream non-IT ancillary devices installed in IT racks, such as fans. If the PDU system supports non-IT equipment (e.g., computer room air-conditioning units, computer room air handlers, in-row coolers), this equipment must be metered and subtracted from the PDU output reading. The metering approach should be consistent with the metering required for the power usage efficiency (PUE) category (e.g., continuous consumption metering for PUE categories 1, 2, and 3).

情報機器(IT機器)に電力を割り当て、供給する装置から出力される電力。 配電盤ユニット(PDU)出力には、PDU内で発生する変換効率のロスは含めないが、〈PDUより〉下流のITラック内の、例えばファンのような、非IT補助機器の電力は含める。 PDUシステムが非IT機器をサポートしている場合(コンピュータールームのエアコン、コンピュータールームの空調器、列内クーラーなど)、これらの機器〈の電力〉を測定し、PDU出力読み取り値から差し引かなければならない。 測定手法は、電力使用効率(PUE)カテゴリーで要求される測定方法と一致しなければならない(PUEカテゴリー1、2、3の連続消費測定など)。

power utilization effectiveness (PUE)


a measure of how efficiently a data center uses its power; specifically, how much power is used by computing equipment rather than for cooling and other overhead


powered floor maintenance equipment


electric and battery-powered floor buffers and burnishers. It does not include equipment used in wet applications

電気・バッテリー式の床バッファーおよびバニッシャー〈磨き仕上げ機〉。 濡れた適用箇所で使用される装置は含まない。

preconsumer recycled content


matter diverted from the waste stream during the manufacturing process, determined as the percentage of material, by weight. Examples include planer shavings, sawdust, bagasse, walnut shells, culls, trimmed materials, overissue publications, and obsolete inventories. The designation excludes rework, regrind, or scrap materials capable of being reclaimed within the same process that generated them (ISO 14021). Formerly known as postindustrial content.


preferred parking


the parking spots closest to the main entrance of a building (exclusive of spaces designated for handicapped persons). For employee parking, it refers to the spots that are closest to the entrance used by employees.


premature obsolescence


the wearing out or disuse of components or materials whose service life exceeds their design life. For example, a material with a potential life of 30 years is intentionally designed to last only 15 years, such that its remaining 15 years of service is potentially wasted. In contrast, components whose service life is the same as their expected use are utilized to their maximum potential.


previously developed


altered by paving, construction, and/or land use that would typically have required regulatory permitting to have been initiated (alterations may exist now or in the past). Land that is not previously developed and landscapes altered by current or historical clearing or filling, agricultural or forestry use, or preserved natural area use are considered undeveloped land. The date of previous development permit issuance constitutes the date of previous development, but permit issuance in itself does not constitute previous development.


previously developed site


a site that, prior to the project, consisted of at least 75% previously developed land


prime farmland


land that has the best combination of physical and chemical characteristics for producing food, feed, forage, fiber, and oilseed crops and that is available for these uses, as determined by the U.S. Department of Agriculture’s Natural Resources Conservation Service (a U.S.-based methodology that sets criteria for highly productive soil). For a complete description of what qualifies as prime farmland, see U.S. Code of Federal Regulations, Title 7, Volume 6, Parts 400 to 699, Section 657.5.

食品、飼料、馬糧、繊維、油料種子作物を生産するための物理的および化学的特性の最適な組み合わせを保有し、米国農務省自然資源保全局が定めた要件を満たす(生産性の高い土壌の基準を設定する米国発の方法論)、これらの用途のために提供できる土地。優良農地の条件についての全文記載については、U.S. Code of Federal Regulations, Title 7, Volume 6, Parts 400 to 699, Section 657.5.を参照。

private meter

product (permanently installed building product)


an item that arrives on the project site either as a finished element ready for installation or as a component to another item assembled on-site. The product unit is defined by the functional requirement for use in the project; this includes the physical components and services needed to serve the intended function of the permanently installed building product. In addition, similar products within a specification can each contribute as separate products.

設置準備の整った完成済みの部品、または現場で組み立てる別製品の構成部品としてプロジェクトの敷地に到着した製品。 製品ユニットは、そのプロジェクトで使用される機能的要件により定義される。これには、恒久的に取り付けられた建物製品が目的の機能を実現するために必要な物理的構成部品およびサービスが含まれる。 また、仕様に含まれる同様の製品も、それぞれ別製品としてとらえられる。

public water supply (PWS)


a system for the provision to the public of water for human consumption through pipes or other constructed conveyances. To be considered public, such system must have at least 15 service connections or regularly serve at least 25 individuals. (Adapted from U.S. Environmental Protection Agency)

パイプやその他の構築された運搬方法により、人間が消費するための公共水を供給するシステム。 公共物と考えられるため、これらは15以上の供給先を有するか、定常的に最低でも25人に供給していなければならない。 (米国環境保護庁(U.S. Environmental Protection Agency)より)
