The built environment has a profound impact on our natural environment, economy, health, and productivity.
Breakthroughs in building science, technology, and operations are now available to designers, builders, operators,
and owners who want to build green and maximize both economic and environmental performance.
Through the L EED'' green building certification program, the U.S. Green Building Council (USGBC) is transforming
the built environment. The green building movement offers an unprecedented opportunity to respond to the most
important challenges of our time, including global climate change, dependence on non sustainable and expensive
sources of energy, and threats to human health. The work of innovative building professionals is a fundamental
driving force in the green building moment. Such leadership is a critical component to achieving USGBC's mission of
a sustainable built environment for all within a generation.
USGBC MEMBERSHIP
USGBC's greatest strength is the diversity of our membership. USGBC is a balanced, consensus based nonprofit
with more than t8,000 member companies and organizations representing the entire building industry. Since its
inception in 1993, USGBC has played a vital role in providing a leadership forum and a unique, integrating force for
the building industry. USGBC's programs have three distinguishing characteristics:
Committee-based
The heart of this effective coalition is our committee structure, in which volunteer members design strategies
that are implemented by staff and expert consultants. Our committees provide a forum for members to resolve
differences, build alliances, and forge cooperative solutions for influencing change in all sectors of the building
industry.
Member-driven
Membership is open and balanced and provides a comprehensive platform for carrying out important programs and
activities. We target the issues identified by our members as the highest priority. We conduct an annual review of
achievements that allows us to set policy, revise strategies, and devise work plans based on members' needs.
Consensus-focused
We work together to promote green buildings, and in doing so, we help foster greater economic vitality and
environmental health at lower costs. We work to bridge ideological gaps between industry segments and develop
balanced policies that benefit the entire industry.

I. LEED° GREEN BUILDING RATING SYSTEM
Background on LEED'
Following the formation of the U.S. Green Building Council (USGBC) in 1993, the organization's members quickly
realized that the sustainable building industry needed a system to define and measure "green buildings." USGBC
began to research existing green building metrics and rating systems. Less than a year after formation, the members
acted on the initial findings by establishing a committee to focus solely on this topic. The composition of the
committee was diverse; it included architects, real estate agents, a building owner, a lawyer, an environmentalist, and
industry representatives. This cross section of people and professions added a richness and depth both to the process
and to the ultimate product.
The first LEED Pilot Project Program, also referred to as LEED Version t.o, was launched at the USGBC Membership
Summit in August 1998. After extensive modifications, LEED Green Building Rating System Version 2.0 was released
in March 2000, with LEED Version 2.1 following in 2002 and LEED Version 2.2 following in zoos.
As LEED has evolved and matured, the program has undertaken new initiatives. In addition to a rating system
specifically devoted to building operational and maintenance issues (LEED for Existing Buildings: Operations
& Maintenance), LEED addresses the different project development and delivery processes that exist in the U.S.
building design and construction market, through rating systems for specific building typologies, sectors, and
project scopes: LEED for Core & Shell, LEED for New Construction, LEED for Schools, LEED for Neighborhood
Development, LEED for Retail, LEED for Healthcare, LEED for Homes, and LEED for Commercial Interiors.
Project teams interact with the Green Building Certification Institute (GBCI) for project registration and
certification. GBCI was established in 2008 as a separately incorporated entity with the support of the U.S. Green
Building Council. GBCI administers credentialing and certification programs related to green building practice.
These programs support the application of proven strategies for increasing and measuring the performance of
buildings and communities as defined by industry systems such as LEED.
The green building field is growing and changing daily. New technologies and products are being introduced into
the marketplace, and innovative designs and practices are proving their effectiveness. The LEED rating systems and
reference guides will evolve as well. Project teams must comply with the version of the rating system that is current
at the time of their registration. USGBC will highlight new developments on its website on a continual basis at www.
usgbc.org.
Features of LED
The LEED Green Building Rating Systems are voluntary, consensus-based, and market-driven. Based on existing and
proven technology, they evaluate environmental performance from a whole building perspective over a building's
life cycle, providing a definitive standard for what constitutes a green building in design, construction, and operation.
The LEED rating systems are designed for rating new and existing commercial, institutional, and residential
buildings. They are based on accepted energy and environmental principles and strike a balance between known,
established practices and emerging concepts. Each rating system is organized into s environmental categories:
Sustainable Sites, Water Efficiency, Energy and Atmosphere, Materials and Resources, and Indoor Environmental
LEED 2009 FOR COMMERCIAL INTERIORS
xl
EFTA00281260
Quality. An additional category, Innovation in Design, addresses sustainable building expertise as well as design
measures not covered under the 5 environmental categories. Regional bonus points are another feature of LEED
and acknowledge the importance of local conditions in determining best environmental design and construction
practices.
The LEED Credit Weightings
In LEED 2009, the allocation of points between credits is based on the potential environmental impacts and human
benefits of each credit with respect to a set of impact categories. The impacts are defined as the environmental
or human effect of the design, construction, operation, and maintenance of the building, such as greenhouse gas
emissions, fossil fuel use, toxins and carcinogens, air and water pollutants, indoor environmental conditions. A
combination of approaches, including energy modeling, life-cycle assessment, and transportation analysis, is used to
quantify each type of impact. The resulting allocation of points among credits is called credit weighting.
LEED 2009 uses the U.S. Environmental Protection Agency's TRACI' environmental impact categories as the basis
for weighting each credit. TRACI was developed to assist with impact evaluation for life-cycle assessment, industrial
ecology, process design, and pollution prevention.
LEED 2009 also takes into consideration the weightings developed by the National Institute of Standards and
Technology (NIST); these compare impact categories with one another and assign a relative weight to each.
Together, the 2 approaches provide a solid foundation for determining the point value of each credit in LEED 2009.
The LEED 2009 credit weightings process is based on the following parameters, which maintain consistency and
usability across rating systems:
■ All LEED credits are worth a minimum oft point.
■ MI LEED credits are positive, whole numbers; there are no fractions or negative values.
■ All LEED credits receive a single, static weight in each rating system; there are no individualized scorecards
based on project location.
■ All LEED rating systems have too base points; Innovation in Design (or Operations) and
■ Regional Priority credits provide opportunities for up tom bonus points.
Given the above criteria, the LEED 2009 credit weightings process involves 3 steps:
1. A reference building is used to estimate the environmental impacts in 13 categories associated with a typical
building pursuing LEE!) certification.
2. The relative importance of building impacts in each category are set to reflect values based on the NIST
weightings.'
3. Data that quantify building impacts on environmental and human health are used to assign points to individual
credits.
Each credit is allocated points based on the relative importance of the building-related impacts that it addresses.
The result is a weighted average that combines building impacts and the relative value of the impact categories.
Credits that most directly address the most important impacts are given the greatest weight, subject to the system
design parameters described above. Credit weights also reflect a decision by LEED to recognize the market
implications of point allocation. The result is a significant change in allocation of points compared with previous
LEED rating systems. Overall, the changes increase the relative emphasis on the reduction of energy consumption
and greenhouse gas emissions associated with building systems, transportation, the embodied energy of water, the
embodied energy of materials, and where applicable, solid waste.
LEED 2009 FOR COMMERCIAL INTERIORS
xii
EFTA00281261
The details of the weightings process vary slightly among individual rating systems. For example, LE ED for Existing
Buildings:
includes credits related to solid waste management but LEED for New Construct ion does not. This
results in a difference in the portion of the environmental footprint addressed by each rating system and the relative
allocation of points. The weightings process for each rating system is fully documented in a weightings workbook.
The credit weightings process will be reevaluated over time to incorporate changes in values ascribed to different
building impacts and building types, based on both market reality and evolving scientific knowledge related to
buildings. A complete explanation of the LEED credit weightings system is available on the USGBC website, at WNW.
pnbC.Olg.
Regional Priority Credits
To provide incentive to address geographically specific environmental issues, USGBC regional councils and chapters
have identified 6 credits per rating system that are of particular importance to specific areas. Each regional priority
credit is worth an additional t point, and a total of 4 regional priority points may be earned. Upon project registration,
LEED-Online automatically determines a project's regional priority credits based on its zip code. If the project
achieves more than 4 regional priority credits, the team can choose the credits for which these points will apply. The
USGBC website also contains a searchable database of regional priority credits.
II. OVERVIEW AND PROCESS
The LEED 2009 Green Building Rating System for Commercial Interiors is a set of performance standards
for certifying the design and construction of tenant spaces for office, restaurant, healthcare, hotel/resort and
education buildings of all sizes, both public and private. The intent is to promote healthful, durable, affordable, and
environmentally sound practices in tenant space design and construction.
Prerequisites and credits in the LEED 2009 for Commercial Interiors Rating System addresses 7 topics:
■ Sustainable Sites (SS)
■ Water Efficiency (WE)
■ Energy and Atmosphere (EA)
■ Materials and Resources (MR)
■ Indoor Environmental Quality (IEQ)
■ Innovation in Design (ID)
■ Regional Priority (RP)
LEED 2009 for Commercial Interiors certifications are awarded according to the following scale:
Certified
40-49 points
Silver
50-59 points
Gold
60-79 points
Platinum
80 points and above
GEM will recognize buildings that achieve t of these rating levels with a formal letter of certification.
When to Use LEED 2009 for Commercial Interiors
LEED zoo9 for Commercial Interiors addresses the specifics of tenant spaces primarily in office, retail, and
institutional buildings. Tenants who lease their space or do not occupy the entire building are eligible.
LEED 2009 FOR COMMERCIAL INTERIORS
EFTA00281262
LEED for Commercial Interiors was designed to work hand-in-hand with the LEED for Core & Shell certification
system. LEED for Core & Shell is used by developers to certify the core and shell of a project; it prepares the building
for environmentally conscious tenants.
Many projects clearly fit the defined scope of only1LEED rating system; others may be eligible for a or more. The
project is a viable candidate for LEED certification if it can meet all prerequisites and achieve the minimum points
required in a given rating system. If more than t rating system applies, the project team can decide which to pursue.
For assistance in choosing the most appropriate LEED rating system, please e-mail leedinfo@usgbc.org.
Registration
Project teams interested in earning LEED certification for their buildings must first register the project with GBCI.
Projects can be registered on the GBCI website (www.gbci.org). The website also has information on registration
costs for USGBC national members as well as nonmembers. Registration is an important step that establishes
contact with GBCI and provides access to software tools, errata, critical communications, and other essential
information.
Certification
To earn LEED certification, the applicant project must satisfy all the prerequisites and qualify fora minimum
number of points to attain the established project ratings as listed below. Having satisfied the basic prerequisites of
the program, applicant projects are then rated according to their degree of compliance within the rating system.
LEED 2009 for Commercial Interiors provides the option of splitting a certification application into two phases,
design and construction, in lieu of a combined design and construction review. Documentation for design phase
credits, identified in LEED-Online, can be submitted for review at the end of the design phase; the submittals for
these credits can be fully evaluated based on documentation available during this phase of the project. For example, if
a project site meets the requirements of LEED for Commercial Interiors SS Credit 3.1, Alternative Transportation—
Public Transportation Access, the likelihood of credit achievement can be assessed prior to the completion of
construction. The LEED credit itself, however, is not awarded at the design review stage.
For more information on the LEED certification process including LEED-Online, Credit Interpretation Requests and
Rulings,Appeals, and Fees please see the LEED Reference Guide for Green Building Design and Construction, 2009
Edition and visit www.us gbcAL or www.gbclorg.
III. MINIMUM PROGRAM REQUIREMENTS
The LEED zoo9 Minimum Program Requirements (MPRs) define the minimum characteristics that a project
must possess in order to be eligible for certification under LEED 2009. These requirements define the categories
of buildings that the LEED rating systems were designed to evaluate, and taken together serve three goals: to give
clear guidance to customers, to protect the integrity of the LEED program, and to reduce challenges that occur
during the LEED certification process. It is expected that MPRs will evolve over time along with LEED rating system
improvements. The requirements will apply only to those projects registering under LEED 2009.
To view the list of MPRs, please read the Minimum Program Requirements section of this document.
IV. EXEMPLARY PERFORMANCE STRATEGIES
Exemplary performance strategies result in performance that greatly exceeds the performance level or expands the
scope required by an existing LEED 2009 for Commercial Interiors credit. To earn exemplary performance credits,
teams must meet the performance level defined by the next step in the threshold progression. For credits with more
LEED 2009 FOR COMMERCIAL INTERIORS
xlv
EFTA00281263
than 1 compliance path, an Innovation in Design point can be earned by satisfying more than t compliance path if
their benefits are additive.
The credits for which exemplary performance points are available through expanded performance or scope are noted
in the LEED Reference Guide for Green Interior Design and Construction, 2009 Edition and in LEED-Online.

NOTE: Defirctions, exceptions and more extensive guidance on issues in this document are avai ab e 'n a
separate document titled: `LEER 2009 MPR Supplemental Guidance'. Terms that are italicized and underlined
here are defined in the Supplemental Guidance document (they are marked as such only the first time that
they appear).
This document identifies the Minimum Program Requirements (MPRs), or minimum characteristics that a project
must possess in order to be eligible for LEED Certification. LEED projects must complywith each applicable MPR
described below. These requirements define the types of buildings that the LEED Green Building Rating Systems
were designed to evaluate, and taken together serve three goals: to give clear guidance to customers, to protect the
integrity of the LEED program, and to reduce complications that occur during the LEED Certification process. The
requirements in this document will apply to all those, and only those projects certifying under LEED 2009. Projects
that upgrade to LEED 2009 from earlier versions of LEE!) are subject to the MPRs. It is expected that MPRs will
evolve over time with the LE ED rating system, however only those MPRs in place at the time that a LEED project
registers or upgrades will apply to that project.
LEED for New Construction, Core & Shell, Schools, and Existing Buildings: Operations & Maintenance were
designed to evaluate commercial, institutional, or high-rise residential buildings; as such, any project applying for
LEED Certification under one of these rating systems must include a building that falls under one of these categories.
LEED for Commercial Interiors was designed to evaluate interior spaces of commercial or institutional buildings; as
such, projects applying for certification under LEED for Commercial Interiors must include a space that falls under
one of these categories.
NOTE: CERTIFICATION MAY BE REVOKED FROM ANY LEED PROJECT UPON GAINING KNOWLEDGE OF
NON-COMPLIANCE WITH ANY APPLICABLE MPR. IF SUCH A CIRCUMSTANCE OCCURS, REGISTRATION
AND/OR CERTIFICATION FEES WILL NOT BE REFUNDED.
All exceptions to MPRs that are not already defined in the LEED 2009 MPR Supplemental Guidance
document will be considered on a case-by-case basis for special circumstances. Details on the process for
review of MPR clarification requests will be posted in summer 2009.
LEED 2009 Minimum Requirements for Commercial Interiors
1. Must Comply with Environmental Laws
The LEED project building or space, all other real property within the LEED project boundary, and all go 'e
work
must comply with all applicable federal, state, and local building-related environmental laws and regulations in
place where the project is located. This condition must be satisfied from the date of LEED project registration or
the initiation of schematic design, whichever comes first, until the date that the building receives a certificate of
occupancy or similar official indication that it is ready for use.
2. Must be a Complete, Permanent Building or Space
All LEED projects must be designed for, constructed on, and operated on a permanent location on already
existing land. No building or space that is designed to move at any point in its lifetime may pursue LEED
Certification.
The LEED project scope must include a complete interior space distinct from other spaces within the same
building with regards to at least one of the following characteristics: ownership, management, lease, or party wall
separation.
LEED 2009 FOR COMMERCIAL INTERIORS
xvi
EFTA00281265
Additionally, construction prerequisites and credits may not be submitted for review until substantial completion
of construction has occurred.
3. Must Use a Reasonable Site Boundary
If any land was or will be disturbed for the purpose of undertaking the LEED project, then that land must be
included within the LEED project boundary.
4. Must Comply with Minimum Floor Area Requirements
The LEED project must include a minimum of 250 square feet (22 square meters) of gross floor area.
5. Must Comply with Minimum Occupancy Rates
Full Time Equivalent Occupancy
The LEED project must server or more Pull Time Equivalent (FTE) occupant(s), calculated as an annual average
in order to use LEED in its entirety. If the project serves less than 1 annualized FTE, optional credits from the
Indoor Environmental Quality category may not be earned (the prerequisites must still be earned).
6. Must Commit to Sharing Whole-Building Energy and Water Usage Data
All certified projects must commit to sharing with USGBC and/or GBCI all available actual whole-project energy
and water usage data fora period of at least 5 years. This period starts on the date that the LEED project begins
typical physical occupancy if certifying under New Construction, Core & Shell, Schools, or Commercial Interiors,
or the date that the building is awarded certification if certifying under Existing Buildings: Operations &
Maintenance. Sharing this data includes supplying information on a regular basis in a free, accessible, and secure
online tool or, if necessary, taking any action to authorize the collection of information directly from service or
utility providers. This commitment must carry forward if the building or space changes ownership or lessee.
7. Must Comply with a Minimum Building Area to Site Area Ratio
The gross floor area of the LEED project building must be no less than 2% of the gross land area within the LEED
project boundary.

EA Prerequisite 1: Fundamental Commissioning of Building Energy Systems
Required
Intent
'lb verify that the project's energy-related systems are installed and calibrated to performing according to the
owner's project requirements, basis of design and construction documents.
Benefits of commissioning include reduced energy use, lower operating costs, fewer contractor callbacks, better
building documentation, improved occupant productivity, and verification that the systems perform in accordance
with the owner's project requirements.
Requirements
The following commissioning process activities must be completed by the project team:
■ Designate an individual as the commissioning authority (CxA) to lead, review and oversee the completion of
the commissioning process activities.
• The CxA must have documented commissioning authority experience in at least 2. building projects.
• The individual serving as the CxA must be independent of the project's design and construction
management, though the CxA may be an employee of any firms providing those services. The CxA may be a
qualified employee or consultant of the owner.
• The CxA must report results, findings and recommendations directly to the owner.
• For projects smaller than 50,000 gross square feet, the ocA maybe a qualified person on the design or
construction teams who has the required experience.
■ The owner must document the owner's project requirements. The design team must develop the basis of
design. The CxA must review these documents for clarity and completeness. The owner and design team must
be responsible for updates to their respective documents.
■ Develop and incorporate commissioning requirements into the construction documents.
■ Develop and implement a commissioning plan.
■ Verify the installation and performance of the systems to be commissioned.
■ Complete a summary commissioning report.
Commissioned Systems
Commissioning process activities must be completed for the following energy-related systems at a minimum:
■ Heating, ventilating, air conditioning and refrigeration (HVAC&R) systems (mechanical and passive) and
associated controls.
■ Lighting and daylighting controls.
■ Domestic hot water systems.
■ Renewable energy systems (e.g. PV, wind, solar).
LEED 2009 FOR COMMERCIAL INTERIORS
13
EFTA00281280
Potential Technologies & Strategies
Engage a CxA as early as possible in the design process. Determine the owner's project requirements, develop
and maintain a commissioning plan for use during design and construction and incorporate commissioning
requirements in bid documents. Assemble the commissioning team, and prior to occupancy verify the performance
of energy consuming systems. Complete the commissioning reports with recommendations prior to accepting the
commissioned systems.
Owners are encouraged to seek out qualified individuals to lead the commissioning process. Qualified individuals are
identified as those who possess a high level of experience in the following areas:
■ Energy systems design, installation and operation.
■ Commissioning planning and process management.
■ Hands-on field experience with energy systems performance, interaction, start-up, balancing, testing,
troubleshooting, operation and maintenance procedures.
■ Energy systems automation control knowledge.
Owners are encouraged to consider including water-using systems, building envelope systems, and other systems in
the scope of the commissioning plan as appropriate. The building envelope is an important component of a facility
which impacts energy consumption, occupant comfort and indoor air quality. While this prerequisite does not
require building envelope commissioning, an owner can achieve significant financial savings and reduce risk of poor
indoor air quality by including it in the commissioning process.

Requirements
Design portions of the building as covered by the tenant's scope of work to complywith ANSI/ASHRAWIESNA
Standard 90.1-2007 (with errata but without addenda'), and complete the following:
■ Complywith the mandatory provisions (Sections 5.4, 64,74 84 94 and 104) of ANSI/ASH RAE/I ESNA
Standard 90.1-2007 (with errata but without addenda').
■ Achieve the prescriptive requirements (Sections 5.5,6.5, 7.5 and 9.5) or performance requirements (Section t t)
ofANSIJASHRAWIESNA Standard 90.1-2007 (with errata but without addenda').
■ Reduce connected lighting power densityro% below that allowed by ANSIJASHRAEJIESNA Standard 90.1-
2007 (with errata but without addenda') using either the Space-by-Space Method or by applying the whole
building lighting power allowance to the entire tenant space.
■ Install ENERGY STAR qualified equipment for 50% (by rated-power) of ENERGY STAR eligible equipment'
installed as part of the tenant's scope of work. This requirement includes appliances, office equipment,
electronics, and commercial food service equipment. Excluded are heating, ventilating and air conditioning
(HVAC), lighting, and building envelope products.
Projects in California may use Title 24-2005, Part 6 in place of ANSIJASHRAE/IESNA Standard 90.1-2007.
Potential Technologies & Strategies
Design the systems impacted in the tenant's scope of work to maximize energy performance. Use a computer
simulation model to assess the energy performance and identify the most cost-effective energy measures. Quantify
energy performance compared with a baseline building.
If local code has demonstrated quantitative and textual equivalence following, at a minimum, the U.S. Department
of Energy (DOE) standard process for commercial energy code determination, then the local code may be used
to satisfy this prerequisite in lieu ofANSIJASHRAEfIESNA Standard 90.1-2007. Details on the DOE process for
commercial energy code determination can be found athttp:/Jwww.energycodes.gov/implementfdeterminations_

IEQ Credit 3.1: Construction Indoor Air Quality Management Plan—During
Construction
1 point
Intent
To reduce indoor air quality (IAQ) problems resulting from construction or renovation and promote the comfort
and well-being of construction workers and building occupants.
Requirements
Develop and implement an IAQ management plan for the construction and preoccupancy phases of the tenant space
as follows:
■ During construction, meet or exceed the recommended design approaches of the Sheet Metal and Air
Conditioning National Contractors Association (SMACNA) IAQ Guidelines for Occupied Buildings Under
Construction, and Edition 2007, ANSI/SMACNA 008-2o08 (Chapter 3).
■ Protect stored on-site and installed absorptive materials from moisture damage.
■ If permanently installed air handlers are used during construction, filtration media with a minimum efficiency
reporting value (MERV) of 8 must be used at each return air grille, as determined by ASHRAE 52.2-1999. (with
errata but without addenda').Replace all filtration media immediately prior to occupancy.
Potential Technologies & Strategies
Adopt an IAQ management plan to protect the heating, ventilating and air conditioning (HVAC) system during
construction, control pollutant sources and interrupt contamination pathways. Sequence the installation of
materials to avoid contamination of absorptive materials, such as insulation, carpeting, ceiling tile and gypsum
wallboard. Coordinate with IEQ Credit 3.2: Construction IAQ Management Plan - Before Occupancy and IEQ
Credit 5: Indoor Chemical & Pollutant Source Control to determine the appropriate specifications and schedules for
filtration media.
If possible, avoid using permanently installed air handlers for temporary heating/cooling during construction.
Consult the LEED Reference Guide for Green Interior Design and Construction, 2039 Edition for more detailed
information on how to ensure the well-being of construction workers and building occupants if permanently
installed air handlers must be used during construction.

IEQ Credit 3.2: Construction Indoor Air Quality Management Plan—Before
Occupancy
1 point
Intent
To reduce indoor air quality (IAQ) problems resulting from construction or renovation and promote the comfort
and well-being of workers and occupants.
Requirement
Develop an IAQ management plan and implement it after all finishes have been installed and the building has been
completely cleaned before occupancy.
OPTION 1. Flush-Out'
PATH 1
After construction ends, prior to occupancy and with all interior finishes installed, install new filtration media
and flush-out the building by supplying a total air volume of 14,00o cubic feet of outdoor air per square foot
of floor area while maintaining an internal temperature of at least 60oF and, where mechanical cooling is
operated, relative humidity no higher than 60%.
OR
PATH 2
If occupancy is desired prior to completion of the flush-out, the space may be occupied following delivery of
a minimum of 3,sec cubic feet of outdoor air per square foot of floor area. Once the space is occupied, it must
be ventilated at a minimum rate of 0.30 cubic feet per minute (cfm) per square foot of outside air or the design
minimum outside air rate determined in EQ Prerequisite Minimum IAQ Performance, whichever is greater.
During each day of the flush-out period, ventilation must begin a minimum of 3 hours prior to occupancy and
continue during occupancy. These conditions must be maintained until a total of 4,000 cubic feet per square
foot of outside air has been delivered to the space.
OR
OPTION 2. Air Testing
Conduct baseline IAQ testing after construction ends and prior to occupancy, using testing protocols consistent
with the EPA Compendium of Methods for the Determination of Air Pollutants in Indoor Air and as additionally
detailed in the LEED Reference Guide for Green Interior Design and Construction, 2009 Edition.

*This test is required only it carpets and labia with styrene butadiene rubber ISBRI latex backing are installed as part of the base building systems.
For each sampling point where the maximum concentration limits are exceeded, conduct an additional flush-out
with outside air and retest the noncompliant concentrations. Repeat until all requirements have been met. When
retesting noncompliant building areas, take samples from the same locations as in the first test.
Conduct the air sample testing as follows:
• All measurements must be conducted prior to occupancy, but during normal occupied hours, with the
building ventilation system started at the normal daily start time and operated at the minimum outside air
flow rate for the occupied mode throughout the test.
■ All interior finishes must be installed, including but not limited to millwork, doors, paint, carpet and
acoustic tiles. Movable furnishings such as workstations and partitions must be in place.
■ The number of sampling locations will depend on the size of the building and number ofventilation
systems. For each portion of the building served by a separate ventilation system, the number of sampling
points must not be less than 1 per 25,oOO square feet or for each contiguous floor area, whichever is larger.
Include areas with the least ventilation and greatest presumed source strength.
■ Air samples must be collected between 3 and 6 feet from the floor to represent the breathing zone of
occupants, and over a minimum 4-hour period.
Potential Technologies & Strategies
Prior to occupancy, perform a building flush-out or test the air contaminant levels in the building. The flush-out
is often used where occupancy is not required immediately upon substantial completion of construction. IAQ
testing can minimize schedule impacts but maybe more costly. Coordinate with IEQ Credit 3.1: Construction
IAQ Management Plan—During Construction and IEQ Credit 5: Indoor Chemical & Pollutant Source Control to
determine the appropriate specifications and schedules for filtration media.
The intent of this credit is to eliminate IAQ problems that occur as a result of construction. Architectural finishes
used in tenant build-outs constitute a significant source of air pollutants and must be addressed in order to qualify

Demonstrate, through records of indoor light measurements that a minimum daylight illumination level of 25 fc
has been achieved in at least 75% (t point) or 90% (2 points) of all regularly occupied areas. Measurements must
be taken on a to-foot grid for all occupied spaces and recorded on building floor plans.
Only the square footage associated with the portions of rooms or spaces meeting the minimum illumination
requirements may be counted in the calculations.
For all projects pursuing this option, provide daylight redirection and/or glare control devices to avoid high
contrast situations that could impede visual tasks. Exceptions for areas where tasks would be hindered by
daylight will be considered on their merits.
OR
OPTION 4. Combination
Any of the above calculation methods may be combined to document the minimum daylight illumination in at
least 75% (1 point) or 90% (a points) of all regularly occupied spaces. The different methods used in each space
must be clearly recorded on all building plans.
In all cases, only the square footage associated with the portions of rooms or spaces meeting the requirements
maybe applied toward the 75% (t point) or go% (a points) of total area calculation required to qualify for this
credit.
In all cases, provide glare control devices to avoid high-contrast situations that could impede visual tasks.
Exceptions for areas where tasks would be hindered by the use of daylight will be considered on their merits.

Potential Technologies & Strategies
Design the tenant space to maximize interior daylighting. Strategies to consider include lower partition heights,
interior shading devices, interior glazing and high ceiling reflectance values; additionally, automatic photocell-based
controls can help reduce energy use. Predict daylight factors via manual calculations or model daylighting strategies
with a physical or computer model to assess foot-candle levels and daylight factors achieved.

IEQ Credit 8.2: Daylight and Views—Views for Seated Spaces
1 point
Intent
'lb provide the building occupants a connection to the outdoors through the introduction of daylight and views into
the regularly occupied areas of the tenant space.
Requirements
Achieve a direct line of sight to the outdoor environment via vision glazing between 30 inches and 90 inches above
the finish floor for building occupants in 90% of all regularly occupied areas. Determine the area with a direct line of
sight by totaling the regularly occupied square footage that meets the following criteria:
■ In plan view, the area is within sight lines drawn from perimeter vision glazing.
■ In section view, a direct sight line can be drawn from a point 42 inches above the floor (typical seated eye
height) to perimeter vision glazing.
The line of sight may be drawn through interior glazing. For private offices, the entire square footage of the office may
be counted if 75% or more of the area has a direct line of sight to perimeter vision glazing. If less than 75% of the area
has a direct line of sight, only the area with the direct line of sight count toward meeting the credit requirement. For
multi-occupant spaces, the actual square footage with a direct line of sight to perimeter vision glazing is counted.
Potential Technologies & Strategies
Design the tenant space to maximize daylighting and view opportunities. Strategies to consider include lower
partitions, interior shading devices, interior glazing and automatic photocell-based controls.
