Commissioning Specification ‘The contract document that details the objective, scope, and
implementation of the construction and acceptance phases of the commissioning process as
developed in the design-phase commissioning plan.’
Commissioning Team ‘Those people responsible for working together to carry out the
commissioning process.’
Community ‘An interacting population of individuals living in a specific area.’
Completed Design Area ‘The total area of finished ceilings, finished floors, full-height walls
and demountable partitions, interior doors, and built-in case goods in the space when the
project is completed: exterior windows and exterior doors are not considered.’
Composite Wood ‘A product consisting of wood or plant particles or fibers bonded together
by a synthetic resin or binder (i.e., plywood, particleboard, OSB, MDF, composite door
cores). For the purposes of LEED-NC requirements, products must comply with the following
conditions:
1. The product is inside of the building’s waterproofing system.
2. Composite wood components used in assemblies are included (e.g., door cores,
panel substrates, plywood sections of I-beams).
3. The product is part of the base building system.’

Composting Toilet Systems ‘Dry plumbing fixtures that contain and treat human waste via
microbiological processes.’
Construction and Demolition (C&D) Debris ‘Waste and recyclables generated from construction,
renovation, and demolition or deconstruction of preexisting structures. Land-clearing debris
including soil, vegetation, rocks, etc., is not to be included.’
Conventional Irrigation ‘Most common irrigation system used in the region where the
building is located. A common conventional irrigation system uses pressure to deliver water
and distributes it through sprinkler heads above the ground.’
Curfew Hours ‘Locally determined times when greater lighting restrictions are imposed. When
no local or regional restrictions are in place, 10:00 p.m. is regarded as a default curfew time.’
Cutoff Angle Angle between the vertical axis of a luminaire and the first line of sight (of a
luminaire) at which the light source is no longer visible (as per LEED-NC 2.1).
Daylighting ‘The controlled admission of natural light into a space through glazing with the
intent of reducing or eliminating electric lighting. By utilizing solar light, daylighting creates
a stimulating and productive environment for building occupants.’

Development Footprint ‘The area on the project site that has been impacted by any
development activity. Hardscape, access roads, parking lots, nonbuilding facilities, and
building structure are all included in the development footprint.’
Direct Line of Sight to Perimeter Vision Glazing ‘The approach used to determine the calculated
area of regularly occupied areas with direct line of sight to perimeter vision glazing. The area
determination includes full-height partitions and other fixed construction prior to installation
of furniture.’
Drip Irrigation ‘A high-efficiency irrigation method in which water is delivered at low pressure
through buried mains and submains. From the submains, water is distributed to the soil from
a network of perforated tubes or emitters. Drip irrigation is a type of microirrigation.’
