The system is designed to combine the flexibility of buses with the efficiency of rail. For the purposes of LEED, this excludes leather and other animal hides. The designation excludes rework, regrind, or scrap materials capable of being reclaimed within the same process that generated them ISO Projects must also have in place ylossary and learning heating and cooling controls that provide usage feedback. RECs are sold separately from electricity itself and thus allow the purchase of green power by a user of conventionally generated glosdary.

Producers recover and recycle the materials for use in new products of the same type.

USGBC Perspective: Understanding Credit Options in LEED v4 O+M

Individual occupant spaces may be within multioccupant spaces and should be treated separately where possible. Because of its small size, it has novel properties generally not seen in its conventional bulk counterpart.

Glossagy from Lawrence Berkeley National Laboratory. Any remaining ingredients must consist of USDA-approved nonagricultural substances or agricultural products that are not commercially available in organic form.


To view the latest changes as of April In addition, similar product within a specification, each contributes as a separate product. For conditions a and b above, any fraction of the perimeter that borders a water body is excluded from the calculation.

This glossaru requires a newer version to work correctly. The database is specific to countries and regions within countries. While a more challenging credit, many projects opt to pursue Thermal Comfort because of its direct correlation to occupant satisfaction. Incandescent lighting has a color rendering index above 95; standard high-pressure sodium lighting such as orange-hued roadway lights measures approximately 25; many fluorescent sources using rare earth phosphors have blossary color rendering index of 80 and above.

The master plan boundary considers future sustainable use, expansion, om& contraction. Automated facilities such as ATMs or vending machines are not included. Also known as salvage.

Adapted from Green Roofs for Healthy Cities. Rodenticides are never considered least-risk pesticides.

The unit name depends on the unit of lewd for area: Remediation decisions rely on information generated during site assessments. In contrast, components whose service life is the same as their expected use are utilized to their maximum potential. Water budgets must be associated with a specified amount of time, such as a week, glosdary, or year and a quantity of water such as kGal, or liters.

Does not include structured parking. A remanufactured product can be expected to perform as if it were new. The product unit is defined by the functional requirement for use in the project; this includes the physical components and services needed to serve the intended function of the permanently installed building product.


It is defined as the percentage of an analysis area that exceeds a specified direct sunlight illuminance level more than a flossary number of hours per year. It does not include any door exclusively designated as an emergency exit, or a garage door not designed as a pedestrian entrance.

Occupied spaces are further classified as regularly occupied or nonregularly occupied spaces based on the duration of the occupancy, individual or multioccupant based on the quantity of occupants, and densely or nondensely occupied spaces based on the concentration of occupants in the space. These are engineered practices that may require specialized design assistance. Existing glossry pursuing LEED certification can provide annual financial support specifically to the National Fish and Wildlife Foundation or the Amazonas Sustainable Foundation — two organizations working to conserve existing natural areas and promote biodiversity — if efforts cannot be implemented on site.

During the Performance Period, the system must:. Typically, the extent and nature of the work is such that the primary function space cannot be used for its intended purpose while the work is in progress and where a new certificate of occupancy is required before the work area can be reoccupied.

Also known as cogeneration. Examples include water, carbon dioxide, and ammonia.
