LEED for Commercial Interiors
LEED for Commercial Interiors is the green benchmark for the tenant improvement market.
LEED for Commercial Interiors is the recognized system for certifying high-performance green tenant spaces that are healthy, productive places to work; are less costly to operate and maintain; and have a reduced environmental footprint. It gives tenants and designers, who do not always have control over whole building operations, the power to make sustainable choices. Making these choices during tenant improvements and interior renovations can dramatically affect the indoor environment.
This rating system was developed specifically for tenants in commercial and institutional buildings who lease their space or don’t occupy the entire building.
LEED for Commercial Interiors was designed to work hand-in-hand with the LEED for Core & Shell rating system, used by developers to certify the core and shell of a project and prepare the building for environmentally conscious tenants.
Global Alternative Compliance Paths are available for this rating system.

  12. 12. I. LEED® Green Building Rating SystemBackground on LEED®Following the formation of the U.S. Green Building Council (USGBC) in 1993, the organization’s members quicklyrealized that the sustainable building industry needed a system to define and measure “green buildings.” USGBCbegan to research existing green building metrics and rating systems. Less than a year after formation, the membersacted on the initial findings by establishing a committee to focus solely on this topic. The composition of thecommittee was diverse; it included architects, real estate agents, a building owner, a lawyer, an environmentalist, andindustry representatives. This cross section of people and professions added a richness and depth both to the processand 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 releasedin 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 systemspecifically 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, andproject scopes: LEED for Core & Shell, LEED for New Construction, LEED for Schools, LEED for NeighborhoodDevelopment, 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 andcertification. GBCI was established in 2008 as a separately incorporated entity with the support of the U.S. GreenBuilding 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 ofbuildings 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 intothe marketplace, and innovative designs and practices are proving their effectiveness. The LEED rating systems andreference guides will evolve as well. Project teams must comply with the version of the rating system that is currentat the time of their registration.USGBC will highlight new developments on its website on a continual basis at www.usgbc.org.Features of LEED®The LEED Green Building Rating Systems are voluntary, consensus-based, and market-driven. Based on existing andproven technology, they evaluate environmental performance from a whole building perspective over a building’slife 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 residentialbuildings. 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 LEED 2009 for Commercial Interiors xi
  13. 13. Quality. An additional category, Innovation in Design, addresses sustainable building expertise as well as designmeasures not covered under the 5 environmental categories. Regional bonus points are another feature of LEEDand acknowledge the importance of local conditions in determining best environmental design and constructionpractices.The LEED Credit WeightingsIn LEED 2009, the allocation of points between credits is based on the potential environmental impacts and humanbenefits of each credit with respect to a set of impact categories. The impacts are defined as the environmentalor human effect of the design, construction, operation, and maintenance of the building, such as greenhouse gasemissions, fossil fuel use, toxins and carcinogens, air and water pollutants, indoor environmental conditions. Acombination of approaches, including energy modeling, life-cycle assessment, and transportation analysis, is used toquantify 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 TRACI1 environmental impact categories as the basisfor weighting each credit. TRACI was developed to assist with impact evaluation for life-cycle assessment, industrialecology, process design, and pollution prevention.LEED 2009 also takes into consideration the weightings developed by the National Institute of Standards andTechnology (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 andusability 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 systemdesign 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 previousLEED rating systems. Overall, the changes increase the relative emphasis on the reduction of energy consumptionand greenhouse gas emissions associated with building systems, transportation, the embodied energy of water, theembodied energy of materials, and where applicable, solid waste.LEED 2009 for Commercial Interiorsxii
  14. 14. The details of the weightings process vary slightly among individual rating systems. For example, LEED for ExistingBuildings: O&M includes credits related to solid waste management but LEED for New Construction does not. Thisresults in a difference in the portion of the environmental footprint addressed by each rating system and the relativeallocation 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 differentbuilding impacts and building types, based on both market reality and evolving scientific knowledge related tobuildings. A complete explanation of the LEED credit weightings system is available on the USGBC website, atwww.usgbc.org.Regional Priority CreditsTo provide incentive to address geographically specific environmental issues, USGBC regional councils and chaptershave identified 6 credits per rating system that are of particular importance to specific areas. Each regional prioritycredit 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 project’s regional priority credits based on its zip code. If the projectachieves more than 4 regional priority credits, the team can choose the credits for which these points will apply. TheUSGBC 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 standardsfor certifying the design and construction of tenant spaces for office, restaurant, healthcare, hotel/resort andeducation buildings of all sizes, both public and private. The intent is to promote healthful, durable, affordable, andenvironmentally 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 pointsSilver 50–59 pointsGold 60–79 pointsPlatinum 80 points and aboveGBCI will recognize buildings that achieve 1 of these rating levels with a formal letter of certification.When to Use LEED 2009 for Commercial InteriorsLEED 2009 for Commercial Interiors addresses the specifics of tenant spaces primarily in office, retail, andinstitutional buildings. Tenants who lease their space or do not occupy the entire building are eligible. LEED 2009 for Commercial Interiors xiii
  15. 15. LEED for Commercial Interiors was designed to work hand-in-hand with the LEED for Core & Shell certificationsystem. LEED for Core & Shell is used by developers to certify the core and shell of a project; it prepares the buildingfor environmentally conscious tenants.Many projects clearly fit the defined scope of only 1 LEED rating system; others may be eligible for 2 or more. Theproject is a viable candidate for LEED certification if it can meet all prerequisites and achieve the minimum pointsrequired 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 leedinfo@usgbc.org.RegistrationProject 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 registrationcosts for USGBC national members as well as nonmembers. Registration is an important step that establishescontact with GBCI and provides access to software tools, errata, critical communications, and other essentialinformation.CertificationTo earn LEED certification, the applicant project must satisfy all the prerequisites and qualify for a minimumnumber 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 phasecredits, identified in LEED Online, can be submitted for review at the end of the design phase; the submittals forthese credits can be fully evaluated based on documentation available during this phase of the project. For example, ifa 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 ofconstruction. 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 andRulings, Appeals, and Fees please see the LEED Reference Guide for Green Building Design and Construction, 2009Edition and visit www.usgbc.org or www.gbci.org.III. Minimum Program RequirementsThe LEED 2009 Minimum Program Requirements (MPRs) define the minimum characteristics that a project mustpossess in order to be eligible for certification under LEED 2009. These requirements define the categories ofbuildings that the LEED rating systems were designed to evaluate, and taken together serve three goals: to give clearguidance to customers, to protect the integrity of the LEED program, and to reduce challenges that occur during theLEED certification process. To view the MPRs and the MPR Supplemental Guidance, visit the LEED Resources andTools section of www.usgbc.org/projecttools.IV. Exemplary Performance StrategiesExemplary performance strategies result in performance that greatly exceeds the performance level or expands thescope 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 morethan 1 compliance path, an Innovation in Design point can be earned by satisfying more than 1 compliance path iftheir benefits are additive.LEED 2009 for Commercial Interiorsxiv
  16. 16. The credits for which exemplary performance points are available through expanded performance or scope are notedin the LEED Reference Guide for Green Interior Design and Construction, 2009 Edition and in LEED Online.Endnotes1 Tools for the Reduction and Assessment of Chemical and Other Environmental Impacts (TRACI).

  18. 18. SS Credit 1: Site Selection1–5 PointsIntentTo encourage tenants to select buildings that employ best practices systems and green strategies.RequirementsOPTION 1 Select a LEED certified building (5 points).OROPTION 2 Locate the tenant space in a building that has in place 1 or more of the following characteristics at time of submittal (1 – 5 points). Each of the following options may also be met by satisfying the requirements of the corresponding LEED 2009 for New Construction credit. PATH 1. Brownfield Redevelopment (1 point) A building developed on a site documented as contaminated by an ASTM E1903-97 Phase II Environmental Site Assessment or a local voluntary cleanup program. Projects outside the U.S. may use a local equivalent to ASTM E1903-97 Phase II Environmental Site Assessment. OR A building on a site classified as a brownfield by a local, state, tribal or national government agency, whichever is most stringent. Effective remediation of site contamination must have been completed. PATH 2. Stormwater Design—Quantity Control (1 point) A building that prior to its development had less than or equal to 50% imperviousness and has implemented a stormwater management plan that is equal to or is less than the predevelopment 1 1/2 year 24-hour rate and quantity discharge. OR A building that prior to its development had more than 50% imperviousness and has implemented a stormwater management plan that reduced predevelopment 1 1/2 year 24-hour rate and quantity discharge by 25% of the annual on-site stormwater load. This mitigation can be achieved through a variety of measures such as perviousness of site, stormwater retention ponds, and harvesting of rainwater for reuse. Stormwater values are based on actual local rainfall unless the actual exceeds the 10-year annual average local rainfall, in which case the 10-year annual average should be used. LEED 2009 for Commercial Interiors 1
  19. 19. PATH 3. Stormwater Design—Quality Control (1 point) A building that has in place site stormwater treatment systems designed to remove at least 80% of the average annual site area’s total suspended solids (TSS) and 40% of the average annual site area’s total phosphorus (TP). These values are based on the average annual loadings from all storms less than or equal to the 2-year 24-hour storm. The building must implement and maintain best management practices (BMPs) outlined in Chapter 4, Part 2 Urban Runoff, of the EPA Guidance Specifying Management Measures for Sources of Nonpoint Pollution in Coastal Waters, January 1993 (EPA 840B92002) or the local government’s BMP document, whichever is more stringent. PATH 4. Heat Island Effect—Nonroof (1 point) A building that provides shade (or will provide shade within 5 years of landscape installation); and/ or uses light-colored or high-albedo materials with a solar reflectance index (SRI)1 of at least 29; and/ or has open- grid pavement areas that individually or in total equals at least 30% of the site’s nonroof impervious surfaces, such as parking areas, walkways, plazas, and fire lanes. OR A building that has placed a minimum of 50% of parking spaces underground or covered by structured parking. OR A building that has an open-grid pavement system (less than 50% impervious) for 50% of the parking lot area. PATH 5. Heat Island Effect—Roof (1 point) A building whose roofing has a solar reflectance index (SRI) of the following minimum values for at least 75% of the roof surface; Roof Type Slope SRI Low-sloped roof ≤ 2:12 78 Steep-sloped roof > 2:12 29 OR A building that has installed a vegetated roof for at least 50% of the roof area. OR A building that has both high SRI roofs and vegetated roofs that satisfy the following area requirement: Total Roof Area ≤ [( Area of SRI Roof x 1.33 ) + ( Area of Vegetated Roof x 2 ) ]1 The solar reflectance index (SRI) is a measure of the constructed surface’s ability to reflect solar heat, as shown by a small temperature rise.

The CxA or other project team members must verify that the requirements for training operating personnel n and building occupants have been completed. The CxA must be involved in reviewing the operation of the tenant space with operations and maintenance n (OM) staff and occupants within 8 to 10 months after substantial completion. A plan for resolving outstanding commissioning-related issues must be included.Potential Technologies StrategiesEngage a CxA as early as possible in the design process. Determine the owner’s project requirements, developand maintain a commissioning plan for use during design and construction and incorporate commissioningrequirements in bid documents. Assemble the commissioning team, and prior to occupancy verify the performanceLEED 2009 for Commercial Interiors22

Complete the commissioning reports with recommendations prior to acceptance ofthe 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 knowledgeOwners are encouraged to consider including water-using systems, building envelope systems, and other systems inthe scope of the commissioning plan as appropriate. The building envelope is an important component of a facilitywhich impacts energy consumption, occupant comfort and indoor air quality. While this prerequisite does notrequire 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 onthe rigor expected for the following process activities: n Owner’s project requirements. n Basis of design. n Commissioning plan. n Commissioning specification. n Performance verification documentation. n Commissioning report.

EA Credit 3: Measurement and Verification2–5 pointsIntentTo provide for the ongoing accountability and optimization of tenant energy and water consumption performanceover time.RequirementsCASE 1. Projects Less Than 75% of the Total Building Area Complete 1 or more of the following: n Install submetering equipment to measure and record energy use within the tenant space. (2 points) n Negotiate a lease whereby energy costs are paid by the tenant and not included in the base rent. (3 points)CASE 2. Projects 75% or More of the Total Building Area OPTION 1 Develop and implement a measurement and verification (MV) plan consistent with Option D: Calibrated Simulation (Savings Estimation Method 2) as specified in the International Performance Measurement Verification Protocol (IPMVP) Volume III: Concepts and Options for Determining Energy Savings in New Construction, April 2003. The MV period must cover at least 1 year of post-construction occupancy. Provide a process for corrective action if the results of the MV plan indicate that energy savings are not being achieved. OR OPTION 2 Develop and implement a measurement and verification (MV) plan consistent with Option B: Energy Conservation Measure Isolation, as specified in the International Performance Measurement Verification Protocol (IPMVP) Volume III: Concepts and Options for Determining Energy Savings in New Construction, April 2003. The MV period must cover at least 1 year of post-construction occupancy. Provide a process for corrective action if the results of the MV plan indicate that energy savings are not being achieved.Potential Technologies StrategiesFor projects with an area that constitutes less than 75% of the total building area, tenant space is submetered and hasa direct pay clause in their lease for energy actually used instead of on a square foot basis. For projects with an areathat constitutes 75% or more of the total building area, model the energy and water systems to predict savings. Designthe project with equipment to measure energy and water performance. Draft a MV plan to apply during buildingoperations that compares predicted savings to those actually achieved in the field.LEED 2009 for Commercial Interiors24
  42. 42. EA Credit 4: Green Power5 pointsIntentTo encourage the development and use of grid-source, renewable energy technologies on a net zero pollution basis.RequirementsOPTION 1 Engage in at least a 2-year renewable energy contract to provide at least 50% of the tenant’s electricity from renewable sources, as defined by the Center for Resource Solutions’ Green-e energy product certification requirements or an equivalent. All purchases of green power must be based on the quantity of energy consumed, not the cost, as determined by the annual electricity consumption results of EA Credit 1, Optimize Energy Performance. If the green power is not Green-e Energy certified, equivalence must exist for both major Green-e Energy program criteria: 1) current green power performance standards, and 2) independent, third-party verification that those standards are being met by the green power supplier over time.OROPTION 2 Engage in at least a 2-year renewable energy contract to purchase at least 8 kilowatt hours per square foot per year (0.75 kilowatt hours per square meter per year) from renewable electricity sources as defined by the Center for Resource Solutions (CRS) Green-e Energy’s product certification requirements or an equivalent. All purchases of green power must be based on the quantity of energy consumed, not the cost. If the green power is not Green-e Energy certified, equivalence must exist for both major Green-e Energy program criteria: 1) current green power performance standards, and 2) independent, third-party verification that those standards are being met by the green power supplier over time.Potential Technologies StrategiesDetermine the energy needs of the tenant space and investigate opportunities to engage in a green power contract.Green power is derived from solar, wind, geothermal, biomass or low-impact hydro sources. Visit https://www.green-e.org/energy for details about the Green-e Energy program. The power product purchased to comply withcredit requirements need not be Green-e Energy certified. Other sources of green power are eligible if they satisfythe Green-e Energy program’s technical requirements. Renewable energy certificates (RECs), tradable renewablecertificates (TRCs), green tags and other forms of green power that comply with the technical requirements of theGreen-e Energy program may be used to document compliance with this credit.
