sDA300/50% the percentage of analysis points across the analysis area that meet or exceed this 300 lux value for at least 50% of the analysis period 


server input


the information technology (IT) load as measured at the point of connection (e.g., power receptacle) of the IT device to the electrical power system. Server input captures the actual power load of the IT device exclusive of any power distribution losses and non-IT loads (e.g., rack-mounted fans).

IT機器の電力システムへの接続点(電源コンセントなど)で測定された情報機器の負荷。 サーバー入力とは、あらゆる電力分配損失や非IT負荷(ラック搭載ファンなど)を除き、IT機器の実電力負荷を測定したもの。

service life


the assumed length of time that a building, product, or assembly will be operational for the purposes of a life-cycle assessment


shared multioccupant space


a place of congregation, or where occupants pursue overlapping or collaborative tasks


shell space


an area designed to be fitted out for future expansion. Shell space is enclosed by the building envelope but otherwise left unfinished.

short-term bicycle storage


non-enclosed bicycle parking typically used by visitors for a period of two hours or less.


simple box energy modeling analysis


(also known as “building-massing model energy analysis”) a simple base-case energy analysis that informs the team about the building’s likely distribution of energy consumption and is used to evaluate potential project energy strategies. A simple box analysis uses a basic, schematic building form.


site assessment


an evaluation of an area’s aboveground and subsurface characteristics, including its structures, geology, and hydrology. Site assessments typically help determine whether contamination has occurred and the extent and concentration of any release of pollutants. Remediation decisions rely on information generated during site assessments.

敷地評価とは、敷地の地上部および地下の特性の検証であり、構造、地質、水文学を含む。 敷地評価は一般的に、汚染があるか、汚染物質が広がっているか、濃度が高くなっているかを特定するために使われる。 地盤改良するかどうかは、敷地評価時に提出される情報によって決定される。

site master plan


an overall design or development concept for the project and associated (or potentially associated) buildings and sites. The plan considers future sustainable use, expansion, and contraction. The site master plan is typically illustrated, with building plans (if applicable), site drawings of planned phased development, and narrative descriptions.


soft space an area whose functions can be easily changed. For example, hospital administrative offices could be moved so that this soft space could be converted to a laboratory. In contrast, a lab with specialized equipment and infrastructure would be difficult to relocate.


softscape the elements of a landscape that consist of live, horticultural elements


solar garden/ community renewable energy system


shared solar array or other renewable energy system with grid-connected subscribers who receive credit for the use of renewables using virtual net metering (Adapted from


solar reflectance (SR)


the fraction of solar energy that is reflected by a surface on a scale of 0 to 1. Black paint has a solar reflectance of 0; white paint (titanium dioxide) has a solar reflectance of 1. The standard technique for its determination uses spectrophotometric measurements, with an integrating sphere to determine the reflectance at each wavelength. The average reflectance is then determined by an averaging process, using a standard solar spectrum, as documented by ASTM Standards E903 and E892.

0〜1の段階評価にて表した、〈材料の〉表面で反射する太陽エネルギーの割合である。黒色塗料の日射反射率は 0、白色塗料(二酸化チタン)の日射反射率は 1 となる。それを特定するための標準的手法は、各波長での反射率を特定するために積分球を用いながら、分光光度測定を使用する。ASTM規格E903及びE892に記載がある通り、平均反射率は、標準太陽スペクトルを用いて、平均化処理により特定される。

solar reflectance index (SRI)


a measure of the constructed surface’s ability to stay cool in the sun by reflecting solar radiation and emitting thermal radiation. It is defined such that a standard black surface (initial solar reflectance 0.05, initial thermal emittance 0.90) has an initial SRI of 0, and a standard white surface (initial solar reflectance 0.80, initial thermal emittance 0.90) has an initial SRI of 100. To calculate the SRI for a given material, obtain its solar reflectance and thermal emittance via the Cool Roof Rating Council Standard (CRRC-1). SRI is calculated according to ASTM E 1980. Calculation of the aged SRI is based on the aged tested values of solar reflectance and thermal emittance.

太陽放射を反射して熱放射を放出することにより、低温に保つ構築物表面の性能の尺度である。標準黒色面(初期日射反射率 0.05 、初期熱放射率 0.90 )は 初期SRI「0」、標準白色面(初期日射反射率0.80、初期熱放射率0.90)は初期SRI「100」であると定義される。与えられた材料のSRIを計算するには、クールルーフ評価協議会規格(CRRC-1)を介して、その日射反射率と熱放射率を得る。SRIは、ASTM E1980に従って計算される。経年SRIの計算は、日射反射率と熱放射率の経年テスト値に基づく。

sound-level coverage


a set of uniformity criteria that ensure consistent intelligibility and directionality of audible frequencies for all occupants within a space


source reduction


a decrease in the amount of unnecessary material brought into a building in order to produce less waste. For example, purchasing products with less packaging is a source reduction strategy.

建物に持ち込まれる不要な材料の量を減少することで廃棄物の発生を減らす。 例えば、簡易包装で製品を購入すると、原料節減の戦略となる。

spatial daylight autonomy (sDA)


a metric describing annual sufficiency of ambient daylight levels in interior environments. It is defined as the percentage of an analysis area (the area where calculations are performed, typically across an entire space) that meets a minimum daylight illuminance level for a specified fraction of the operating hours per year (i.e., the Daylight Autonomy value following Reinhart & Walkenhorst, 2001). The illluminance level and time fraction are included as subscripts, as in sDA300,50%. The sDA value is expressed as a percentage of area.

屋内環境の周囲昼光レベルの年間の充足度を示す指標。 これは、年間の特定運用時間の割合に対する最低昼光照度レベルを満たす分析エリアの割合で定義される(計算が実行されるエリア、通常はスペース全体)(Reinhart & Walkenhorst,による昼光の自律性値,2001参照)。照度レベルと時間の比は、sDA300,50%のように添字として含められる。sDA値は、エリアの割合として示される。

a transit service with small, individual rail cars. Spacing between stations is uniformly short and ranges from every block to ¼ mile, and operating speeds are primarily 10–30 mph (15–50 kmh). Streetcar routes typically extend 2–5 miles (3-8 kilometers).

systems manual


provides the information needed to understand, operate, and maintain the systems and assemblies within a building. It expands the scope of the traditional operating and maintenance documentation and is compiled of multiple documents developed during the commissioning process, such as the owner’s project requirements, operation and maintenance manuals, and sequences of operation.
