Q

Infill site

A

A site where at least 75% of the land area, exclusive of rights-of-way, within 1/2 mile of the project boundary is previously developed.

19
Q

Interstitial space

A

An intermediate space located between floors with a walk-on deck, often used to run the majority of the utility distribution and terminal equipment, thus permitting convenient installation, maintenance, and future modifications

20
Q

Landscape water requirement (LWR)

A

The amount of water that the site landscape area(s) requires for the site’s peak watering month

21
Q

Life-cycle inventory

A

A database that defines the environmental effects (inputs and outputs) for each step in a material’s or assembly’s life cycle. The database is specific to countries and regions within countries.

22
Q

Low-impact development

A

An approach to managing rainwater runoff that emphasizes on-site natural features to protect water quality, by replicating the natural land cover hydrologic regime of watersheds, and addressing runoff close to its source.

23
Q

Makeup water

A

Water that is fed into a cooling tower system or evaporative condenser to replace water lost through evaporation, drift, bleed-off, or other causes

24
Q

Master plan boundary

A

The limits of a site master plan. The master plan boundary includes the project area and may include all associated buildings and sites outside of the LEED project boundary.

25
Q

Occupant control

A

A system or sqitch that a person in the space can directly access and use. e.g. task light, open switch, blinds. Does not include sensor-operated controls.

26
Q

Owner’s Project Requirements (OPR)

A

A written document that details the ideas, concepts, and criteria determined by the owner to be important to the success of the project.

27
Q

Peak watering month

A

The month with the greatest deficit between evapotranspiration and rainfall.

28
Q

Power utilization effectiveness (PUE)

A

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.

29
Q

Process energy

A

Power resources consumed in support of a manufacturing, industrial, or commercial process other than conditioning spaces and maintaining comfort and amenities for building occupants (ASHRAE)

30
Q

Public water supply (PWS)

A

To be considered public, system must have at least 15 service connections or regularly serve at least 25 individuals

31
Q

Renewable energy credit (REC)

A

A tradable commodity representing proof that a unit of electricity was generated from a renewable resource.

32
Q

Scope 1 emissions

A

Direct GHG emissions from sources owned or controlled by the entity, such as emissions from fossil fuels burned on site

33
Q

Scope 2 emissions

A

Indirect GHG emissions associated with the generation of purchased electricity, heating/cooling, or steam off site, through a utility provider for the entity’s consumption

34
Q

Simple box energy modeling analysis

A

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, AKA building-massing model energy analysis

35
Q

Site assessment

A

An evaluation of an area’s aboveground and subsurface characteristics, including its structures, geoglogy, and hydrology

36
Q

Site master plan

A

An overall design or development concept for the project and associated (or potentially associated) buildings and sites.
