Examples include reuse and recycling. Examples include the main building entrance as well as any building entryways attached to parking structures, underground parking garages, underground pathways, or outside spaces. During the Establishment Period, the project must have a permanent monitoring system to ensure ongoing building performance to the desired comfort criteria, as specified by ASHRAE Standard 55— Excludes air shafts, pipe trenches, chimneys and floor area dedicated to the parking and circulation of motor vehicles.

RECs are sold separately from electricity itself and thus allow the purchase of green power by a user of conventionally generated electricity. It can also refer to water used in operational processes, such as dishwashing, clothes washing, and ice making. Exterior consists of the elements of a building that separate conditioned spaces from the outside i. While a more challenging credit, many projects opt to pursue Thermal Comfort because of its direct correlation to occupant satisfaction.

It omits the use and the disposal phases of the product. For the purposes of LEED, this excludes leather and other animal hides. The wavelength range for radiant energy is roughly 5 to 40 micrometers.

Examples include paper, toner cartridges, binders, batteries, and desk accessories. BUG ratings supersede the former cutoff ratings. For city projects, this includes customers of all classes billed by the utility, municipality or third-party supplier. Interior finish excludes building structural members, such as beams, trusses, studs, or subfloors, or similar items.

Such substances generally have much lower potential for atmospheric damage than manufactured chemical refrigerants. It is expressed in footcandles in the U. The harvested rainwater can be used for irrigation. It does lees include areas for building equipment, vertical circulation, or structural components. A remanufactured product can be expected to perform as if it were new.

The sum of electric power generated at the generator terminals of local generators. Most building materials including glass are opaque in this part of the spectrum and have an emittance of roughly 0. These are areas that do not qualify as ‘greenfield. In contrast, a lab with specialized equipment and infrastructure would be difficult to relocate.

The higher the index number, the more accurately the light is rendering colors.

Semiexterior consists of the elements of a building that separate conditioned space from unconditioned space or that encloses semi-heated space through which thermal energy may be transferred to or from the exterior or conditioned or unconditioned spaces e. The designation excludes rework, regrind, lsed scrap materials capable of being reclaimed within the same process that generated them ISO Strategies that help cut pollution by leveraging more sustainable land development include the use of self-propelled conveyances e.

Typically, a rain barrel or cistern stores the water; other components include the catchment surface and conveyance system. Downstream equipment includes the thermal connection or interface with the DES, secondary distribution systems in the building, and terminal units.

Wastewater from buildings can be classified as graywater, blackwater, or process wastewater.

Tall buildings and narrow streets reduce airflow and exacerbate the effect. It must include an enclosed passenger seating area, fixed route service, fixed fare structure, regular operation, and the ability to pick up multiple riders. A simple box analysis uses a basic, schematic building form. Examples include energy from the sun, wind, and small low-impact hydropower, plus geothermal energy and wave and tidal systems. Under good weather conditions, civil twilight is the best time to distinguish terrestrial objects clearly.


Projects must meet Option 1 requirements and implement an alternative transportation program that includes at least one element from the following categories: Examples include school boards, local governments, and religious institutions. Hospitality furniture is included as applicable to the project.

Also known as added microbial agent. When used in density calculations, buildable land excludes public rights-of-way and land excluded from development by codified law or LEED for Neighborhood Development prerequisites. Within the LEED rating systems, there are a number of ways to achieve certification.

Site assessments typically help determine whether contamination has occurred and the extent and concentration of any release of pollutants. The budget takes into account indoor, outdoor, process, and makeup water demands and any on site supply including estimated rainfall. This site requires a newer version to work correctly. Clean waste excludes lead and asbestos.

Individual occupant spaces may be within multioccupant spaces and should be treated separately where possible. Waste light does not increase nighttime safety, utility, or security and needlessly consumes energy.

Freight villages may offer logistics services, integrated distribution, warehousing capabilities, showrooms, and support services. Some products, such as linoleum, exhibit natural antimicrobial properties. When used in density calculations, buildable land excludes public rights-of-way and land excluded from development by codified law.

For campuses, this includes business and groups of individuals i. For furniture, such labeling may include radio frequency identification, engraving, embossing, or other permanent marking containing information on material origin, properties, and date glosasry manufacture. In a retail setting, items that are movable but semipermanently attached using mechanical fastening systems for operational use are considered furniture and not base building elements e.
