<環境用語A~Z>Glossary LEED V4(d)

dedicated storage


 a designated area in a building space or a central facility that is sized and allocated for a specific task, such as the collection of recyclable waste. Signage often indicates the type of recyclable waste stored there. Some waste streams, such as mercury-based light bulbs, sensitive paper documents, biomedical waste, or batteries, may require particular handling or disposal methods. Consult the municipality’s safe storage and disposal procedures or use guidelines posted on the U.S. Environmental Protection Agency website, at www.epa.gov.

リサイクル可能廃棄物の収集などの特定の仕事のために適した広さで割り当てられた、建物のスペースまたは中心的施設内での専用エリア。 標識により、そこに保管されているリサイクル可能廃棄物の種類が示されることが多い。 水銀系の電球、感光紙の文書、生物医学廃棄物、バッテリなどの一部の廃棄物の流れは、特定の処理または廃棄方法が求められることがある。 自治体の安全な保管および廃棄手順に従うか、米国環境保護庁( U.S. Environmental Protection Agency)のWebサイト(www.epa.gov)で公開されているガイドラインを使用する。

demand response (DR)


 a change in electricity use by demand-side resources from their normal consumption patterns in response to changes in the price of electricity or to incentive payments designed to induce lower electricity use at times of high wholesale market prices or when system reliability is jeopardized


demand response (DR) event


 a specific period of time when the utility or independent service operator calls for a change in the pattern or level of use in grid-based electricity from its program participants. Also known as a curtailment event.

電力事業者または独立系サービス運用業者がデマンドレスポンスイベントのプログラム参加者に、商用電力の使用パターンや使用量の変更を呼びかける特定の期間。 節減イベントとも呼ぶ。

demountable partition


 a temporary interior wall that can be easily reconfigured. In a health care facility, acoustical concerns and embedded equipment, as in a surgery suite, may prevent demountable partitions from being used


densely occupied space


 an area with a design occupant density of 25 people or more per 1,000 square feet (93 square meters)




 a measure of the total building floor area or dwelling units on a parcel of land relative to the buildable land of that parcel. Units for measuring density may differ according to credit requirements. Does not include structured parking.


departmental gross area (DGA) 

部門総面積 (DGA)

 – the floor area of a diagnostic and treatment of clinical department, calculated from the centerline of the walls separating the department from adjacent spaces. Walls and circulations space within the department are included in the calculation. This calculation excludes inpatient units.


development footprint


 the total land area of a project site covered by buildings, streets, parking areas, and other typically impermeable surfaces constructed as part of the project


differential durability


 a state in which two materials with different life spans make up one complete component. If one material wears out and cannot be separated and replaced, the entire product must be thrown away.

異なる寿命を持つ2つの材料が1つの完全なコンポーネントを構成する状態。 1つの材料が摩滅し、分離および交換できない場合、製品全体を廃棄する必要がある。

direct access


 a means of entering a space without having to leave the floor or pass through another patient’s room, dedicated staff space, service or utility space, or major public space. Patients’ and public circulation corridors, common sitting areas, and waiting and day space may be part of a direct access route.


direct sunlight


 an interior horizontal measurement of 1,000 lux or more of direct beam sunlight that accounts for window transmittance and angular effects, and excludes the effect of any operable blinds, with no contribution from reflected light (i.e., a zero bounce analysis) and no contribution from the diffuse sky component (Adapted from IES)


district energy system (DES)


 a central energy conversion plant and transmission and distribution system that provides thermal energy to a group of buildings (e.g., a central cooling plant on a university campus). It does not include central energy systems that provide only electricity.


diverse use


 a distinct business or organization that provides goods or services intended to meet daily needs and is publicly available. Automated facilities such as ATMs or vending machines are not included. For a full list, see the Appendix.


downstream equipment


 the heating and cooling systems, equipment, and controls located in the project building or on the project site and associated with transporting the thermal energy of the district energy system (DES) into heated and cooled spaces. Downstream equipment includes the thermal connection or interface with the DES, secondary distribution systems in the building, and terminal units.


durable goods


 products with a useful life of approximately two or more years and that are replaced infrequently. Examples include furniture, office equipment, appliances, external power adapters, televisions, and audiovisual equipment.


durable goods waste stream


 the flow of long-lasting products from the project building after they are fully depreciated and have reached the end of their useful life for normal business operations. It includes leased durable goods returned to their owner but does not include durable goods that remain functional and are moved to another floor or building.
