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 LEED 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 USGBCs mission of

a sustainable built environment for all within a generation.

USGBC MeMBerShip

USGBCs greatest strength is the diversity of our membership. USGBC is a balanced, consensus based nonprofit

with more than 18,000 member companies and organizations representing the entire building industry. Since itsinception in 1993, USGBC has played a vital role in providing a leadership forum and a unique, integrating force for

the building industry. USGBCs programs have three distinguishing characteristics:

Cmm-bsd

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.

Mmb-dv

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.

Cssus-cusdWe 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.

Bcgud leeD

Following the formation of the U.S. Green Building Council (USGBC) in 1993, the organizations 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 1.0, was launched at the USGBC MembershipSummit 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 2005.

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 atwww.usgbc.org.

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 buildingslife 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 5 environmental categories:

Sustainable Sites, Water Efficiency, Energy and Atmosphere, Materials and Resources, and Indoor Environmental

7/29/2019 LEED 2009 CI guide

14/84


xi i

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.

t leeD Cd wggsIn 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 Agencys TRACI1 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 of 1 point.

All 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 100 base points; Innovation in Design (or Operations) and

Regional Priority credits provide opportunities for up to 10 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 LEED certification.

2. The relative importance of building impacts in each category are set to reflect values based on the NIST

weightings.2

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 marketimplications 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.

7/29/2019 LEED 2009 CI guide

15/84


xiii

The details of the weightings process vary slightly among individual rating systems. For example, LEED for Existing

Buildings: O&M includes credits related to solid waste management but LEED for New Construction 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

www.usgbc.org.

rg p CdsTo 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 1 point, and a total of 4 regional priority points may be earned. Upon project registration,

LEED Online automatically determines a projects 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 proCeSSThe 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)

institutional buildings. Tenants who lease their space or do not occupy the entire building are eligible.

7/29/2019 LEED 2009 CI guide

16/84


xiv

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 only 1 LEED rating system; others may be eligible for 2 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 1 rating system applies, the project team can decide which to pursue.

For assistance in choosing the most appropriate LEED rating system, please e-mail [email protected].

rgsProject 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.

CfcTo earn LEED certification, the applicant project must satisfy all the prerequisites and qualify for a minimum

number of points to attain the established project ratings as listed below. Having satisfied the basic prerequisites ofthe 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 visitwww.usgbc.org orwww.gbci.org.

iii. MiniMUM proGraM reQUireMentS

The LEED 2009 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. To view the MPRs and the MPR Supplemental Guidance, visit the LEED Resources and

Tools section ofwww.usgbc.org/projecttools.

iV. exeMplary perorManCe 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

than 1 compliance path, an Innovation in Design point can be earned by satisfying more than 1 compliance path if

their benefits are additive.

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 owners project requirements.

rqumsThe following commissioning process activities must be completed by the project team:

n 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 projects 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 CxA may be a qualified person on the design or

construction teams who has the required experience.

n The owner must document the owners 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.

n Develop and incorporate commissioning requirements into the construction documents.

n Develop and implement a commissioning plan.

n Verify the installation and performance of the systems to be commissioned.

n Complete a summary commissioning report.

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:

n Energy systems design, installation and operation.

n Commissioning planning and process management.

n Hands-on field experience with energy systems performance, interaction, start-up, balancing, testing,

troubleshooting, operation and maintenance procedures.

n

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.

rqumsImplement, or have a contract in place to implement, the following additional commissioning process activities in

addition to the requirements of EA Prerequisite 1: Fundamental Commissioning of the Building Energy Systems:

n Prior to the start of the construction documents phase, designate an independent commissioning authority

(CxA) to lead, review and oversee the completion of all 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 work of design and construction;

Must not be an employee of the design firm, though he or she may be contracted through them;

Must not be an employee of, or contracted through, a contractor or construction manager holding

construction contracts;

May be a qualified employee or consultant of the owner.

The CxA must report results, findings and recommendations directly to the owner.

n The CxA must conduct, at a minimum, 1 commissioning design review of the owners project requirements,

basis of design and design documents prior to the mid-construction documents phase and must back-check

the review comments in the subsequent design submission.

n The CxA must review contractor submittals applicable to systems being commissioned for compliance with

the owners project requirements and basis of design. This review must be concurrent with the reviews of the

architect or engineer of record and submitted to the design team and the owner.

n The CxA or other project team members must develop a systems manual that gives future operating staff the

information needed to understand and optimally operate the projects commissioned systems.

n The CxA or other project team members must verify that the requirements for training operating personnel

and building occupants have been completed.

n The CxA must be involved in reviewing the operation of the tenant space with operations and maintenance

(O&M) staff and occupants within 8 to 10 months after substantial completion. A plan for resolving

outstanding commissioning-related issues must be included.

p tcgs & Sgs

Engage a CxA as early as possible in the design process. Determine the owners 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 acceptance of

the commissioned systems.

Owners are encouraged to seek out qualified individuals to lead the commissioning process. Qualified individuals areidentified as those who possess a high level of experience in the following areas:

n Energy systems design, installation and operation

n Commissioning planning and process management

n Hands-on field experience with energy systems performance, interaction, start-up, balancing, testing,

troubleshooting, operation, and maintenance procedures

n 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 receive significant financial savings and reduce risk of poorindoor air quality by including it in the commissioning process.

The LEED Reference Guide for Green Interior Design and Construction, 2009 Edition provides detailed guidance on

the rigor expected for the following process activities:

n Owners project requirements.

n Basis of design.

n Commissioning plan.

n Commissioning specification.

n Performance verification documentation.

that has an open market value (e.g., wood derived fuel [WDF], alternative daily cover material, etc.) may be applied

to the construction waste calculation. Designate a specific area(s) on the construction site for segregated or

commingled collection of recyclable materials, and track recycling efforts throughout the construction process.

Identify construction haulers and recyclers to handle the designated materials, and seek verification that the

diverted materials are recycled or salvaged, as intended. Note that diversion may include donation of materials to

charitable organizations and salvage of materials on site. For commercial interior projects the recycling rate for the

landlords demolition activity (before delivery to the tenant) can contribute to the project calculations for this credit
