<環境用語解説AからZまで>Glossary LEED V4 (a) 


abandoned property


property left behind intentionally and permanently when it appears that the former owner does not intend to come back, pick it up, or use it. One may have abandoned the property of contract rights by not doing what is required by the contract. However, an easement and other land rights are not abandoned property just because of nonuse. Abandoned land is defined as land not being used at the present time but that may have utilities and infrastructure in place.


adapted plant


vegetation that is not native to a particular region but that has characteristics that allow it to live in the area. Adapted plants do not pose the same problems as invasive species.


added antimicrobial treatment


a substance added to a product (e.g., paint, flooring) to kill or inhibit the growth of microorganisms. Some products, such as linoleum, exhibit natural antimicrobial properties. Despite current practice, science has not proven that antimicrobial treatments reduce infection transfer in building finishes more effectively than standard cleaning procedures. Also known as added microbial agent. See U.S. EPA factsheet, Consumer Products Treated with Pesticides (www.epa.gov/pesticides factsheets/treatart.htm).

微生物の殺菌または繁殖抑止のために製品(ペンキや床材のなど)に添加された薬品。リノリウムのような製品には自然な抗菌作用がある。しかし、仕上げの材料に抗菌薬を加えることが、標準的な清掃よりも伝染感染を減らすことは科学的に証明されていない。米国EPAファクトシート「殺菌処理した消費者向け製品」(U.S. EPA factsheet, Consumer Products Treated with Pesticides) (http://www.epa.gov/pesticides/factsheets/treatart.htm) を参照。

adjacent site


a site having at least a continuous 25% of its boundary bordering parcels that are previously developed sites. Only consider bordering parcels, not intervening rights-of-way. Any fraction of the boundary that borders a water body is excluded from the calculation.


alternative daily cover (ADC)


material other than earthen material placed on the surface of the active face of a municipal solid waste landfill at the end of each operating day to control vectors, fires, odors, blowing litter, and scavenging. Generally these materials must be processed so they do not allow gaps in the exposed landfill face. (CalRecycle)


alternative fuel


low-polluting, nongasoline fuels such as electricity, hydrogen, propane, compressed natural gas, liquid natural gas, methanol, and ethanol


alternative water source


nonpotable water from other than public utilities, on-site surface sources, and subsurface natural freshwater sources. Examples include graywater, on-site reclaimed water, collected rainwater, captured condensate, and rejected water from reverse osmosis systems (IgCC).


annual sunlight exposure (ASE)


a metric that describes the potential for visual discomfort in interior work environments. It is defined as the percentage of an analysis area that exceeds a specified direct sunlight illuminance level more than a specified number of hours per year.




a built-in, nonstructural portion of a roof system. Examples include skylights, ventilators, mechanical equipment, partitions, and solar energy panels.

構造体でない屋根部材。 天窓、換気扇、機械的装置、パーティション、太陽光発電パネルなど。

ASE1000,250 reports the percentage of sensors in the analysis area, using a maximum 2-foot spacing between points, that are found to be exposed to more than 1000 lux of direct sunlight for more than 250 hours per year, before any operable blinds or shades are deployed to block sunlight, considering the same 10 hour/day analysis period as sDA and using comparable simulation methods




a product formulated from multiple materials (e.g., concrete) or a product made up of subcomponents (e.g., a workstation)


attendance boundary


the limits used by school districts to determine what school students attend based on where they live


average LED intensity (ALI)


the illumination output for light-emitting diode lamps, as specified in the International Commission on Illumination Standard 127–2007

国際照明委員会 スタンダード 127-2007(the International Commission on Illumination Standard 127–2007)に従って定められたLEDランプの光度。
