1.3 DEFINITIONS

A. Chain-of-Custody: Process whereby a product or material is maintained under the physical possession or control during its entire life cycle.

B. Environmentally preferable products: Products and services that have a lesser or reduced effect on the environment in comparison to conventional products and services. Refer to EPA’s Final Guidance on Environmentally Preferable Purchasing for more information http://www.epa.gov/epp/guidance/finalguidancetoc.htm C. LEED: Leadership in Energy & Environmental Design.

First paragraph below is based on "Requirements" and "Potential Technologies & Strategies" paragraphs in LEED-NC and LEED-CI Credit MR-6. LEED requirements say "made from plants" but LEED includes wool as an example.

D. Rapidly Renewable Materials: Materials made from plants that are typically harvested within a 10-year or shorter cycle. Rapidly renewable materials include products made from bamboo, cotton, flax, jute, straw, sunflower seed hulls, vegetable oils, or wool.

First paragraph below applies to LEED-NC and LEED-CS.

E. Regional Materials: Materials that have been extracted, harvested, or recovered, as well as manufactured, within 500 miles (800km) (800 km)(800 km) of Project site. If only a fraction of a product or material is extracted/harvested/recovered and manufactured locally, then only that percentage (by weight) shall contribute to the regional value.

First two paragraphs below apply to LEED-CI.

F. Regionally Manufactured Materials: Materials that are manufactured within a radius of 500 miles (800km) (800 km)(800 km) (800 km) from Project site. Manufacturing refers to the final assembly of components into the building product that is installed at Project site.

G. Regionally Extracted and Manufactured Materials: Regionally manufactured materials made from raw materials that are extracted, harvested, or recovered within a radius of 500 miles (800km) (800 km)(800 km) (800 km) from Project site.

First paragraph below applies to LEED-NC and LEED-CS.

Note that LEED-NC, LEED-CI, and LEED-CS use the term "pre-consumer" rather than "post-industrial." Also note that when manufacturers and trade associations use the term "post-industrial" it often includes spills, scraps, and damaged and surplus materials that are fed back into the same manufacturing process and that these materials are not considered recycled content by the LEED rating systems.

H. Recycled Content: The recycled content value of a material assembly shall be determined by weight. The recycled fraction of the assembly is then multiplied by the cost of assembly to determine the recycled content value.

1. "Post-consumer" material is defined as waste material generated by households or by commercial, industrial, and institutional facilities in their role as end users of the product, which can no longer be used for its intended purpose.

2. "Pre-consumer" material is defined as material diverted from the waste stream during the manufacturing process. Excluded is reutilization of materials such as rework, regrind, or scrap generated in a process and capable of being reclaimed within the same process that generated it.

Paragraph below applies to LEED-CI.

I. Recycled Content: The percentage by weight of constituents that have been recovered or otherwise diverted from the solid waste stream, either during the manufacturing process (pre-consumer), or after consumer use (post-consumer).

1. Spills and scraps from the original manufacturing process that are combined with other constituents after a minimal amount of reprocessing for use in further production of the same product are not recycled materials.

2. Discarded materials from one manufacturing process that are used as constituents in another manufacturing process are pre-consumer recycled materials.

J. Stewardship: Responsible use and management of resources in support of sustainability.

K. Sustainability: The maintenance of ecosystem components and functions for future generations.

PART 3 - EXECUTION

3.1 CONSTRUCTION INDOOR-AIR-QUALITY MANAGEMENT

First option in first paragraph below applies to LEED-CS; second to LEED-NC and LEED-CI.

A. Comply with SMACNA's "SMACNA IAQ Guideline for Occupied Buildings under Construction."

Coordinate first subparagraph below with Division 01 Section "Temporary Facilities and Controls." Identify air handlers and associated return-air inlets authorized by Owner for use during construction period.

1. If Contracting Officer authorizes use of permanent heating, cooling, and ventilating systems during construction period as specified in Division 01 Section "Temporary Facilities," install filter media having a MERV 8 according to ASHRAE 52.2 at each return-air inlet for the air-handling system used during construction.

2. Replace all air filters immediately prior to occupancy.

B. Comply with one of the following requirements:

Retain one or more of three subparagraphs below. Retain option in paragraph above if retaining more than one subparagraph below. Project's mechanical engineer of record should verify that HVAC system design and equipment indicated are capable of delivering flush-out indicated. Provide HVAC system and equipment operating information necessary to achieve credit. If Project HVAC systems and equipment cannot suit requirement, consider requiring temporary systems and equipment.

1. After construction ends, prior to occupancy and with all interior finishes installed, perform a building flush-out by supplying a total volume of 14,000 cu. ft. (4 300 000 L) of outdoor air per sq. ft. (sq. m) of floor area while maintaining an internal temperature of at least 60 deg F (16 deg C) and a relative humidity no higher than 60 percent.

Indicate operating procedure for each HVAC system and piece of equipment and the operating duration required for flush-out.

2. If occupancy is desired prior to flush-out completion, the space may be occupied following delivery of a minimum of 3,500 cu. ft. (1 070 000 L) of outdoor air per sq. ft. (sq. m) of floor area to the space. Once a space is occupied, it shall be ventilated at a minimum rate of 0.30 cfm per sq. ft. (1.52 L/s per sq. m) of outside air or design minimum outside air rate determined in EQ Prerequisite 1, whichever is greater. During each day of flush-out period, ventilation shall begin a minimum of three hours prior to occupancy and continue during occupancy. These conditions shall be maintained until a total of 14,000 cu. ft./sq. ft. (4 300 000 L/sq. m) of outside air has been delivered to the space.

Indicate operating procedure for each HVAC system and piece of equipment and the operating duration required for flush-out.

3. Air-Quality Testing:

EPA standard referenced in first subparagraph below is available from NTIS by calling (800) 553-6847 with PB90200288 ordering number.

a. Conduct baseline indoor-air-quality testing, after construction ends and prior to occupancy, using testing protocols consistent with EPA's "Compendium of Methods for Determination of Air Pollutants in Indoor Air."

b. Demonstrate that the contaminant maximum concentrations listed below are not exceeded:

Note that it may be necessary to comply with requirements in Credits EQ 4.1, 4.2, 4.3, and 4.4 to comply with the limits specified in first five subparagraphs below.

1) Formaldehyde: 50 ppb.

2) Particulates (PM10): 50 micrograms/cu. m.

3) Total Volatile Organic Compounds (TVOC): 500 micrograms/cu. m.

4) 4-Phenylcyclohexene (4-PH): 6.5 micrograms/cu. m.

5) Carbon Monoxide: 9 ppm and no greater than 2 ppm above outdoor levels.

First subparagraph below is part of LEED credit requirements but creates requirements that are contingent on field conditions that are unknown at time of bid and could influence bids. Also, requirements may result in claims for extra payment and time. Revise to suit office practice.

c. For each sampling point where maximum concentration limits are exceeded, conduct additional flush-out with outside air and retest specific parameters exceeded to indicate that requirements are achieved. Repeat procedure until all requirements are met. When retesting noncomplying building areas, take samples from same locations as in first test.

d. Air-sample testing shall be conducted as follows:

1) All measurements shall be conducted prior to occupancy but during normal occupied hours, and with building ventilation system starting at the normal daily start time and operated at the minimum outside air flow rate for the occupied mode throughout duration of air testing.

2) Building shall have all interior finishes installed including, but not limited to, millwork, doors, paint, carpet, and acoustic tiles. Nonfixed furnishings such as workstations and partitions are encouraged, but not required, to be in place for the testing.

3) Number of sampling locations will vary depending on building size and number of ventilation systems. For each portion of building served by a separate ventilation system, the number of sampling points shall not be less than one per 25,000 sq. ft. (2300 sq. m) or for each contiguous floor area, whichever is larger, and shall include areas with the least ventilation and greatest presumed source strength.

4) Collect air samples between 3 and 6 feet (0.9 and 1.8 m) from the floor to represent breathing zone of occupants, and over a minimum four-hour period.

EPA standard referenced in first subparagraph below is available from NTIS by calling (800) 553-6847 with PB90200288 ordering number.
