10 Rating Systems

11 What is LEED? LEADERSHIP in ENERGY and ENVIRONMENTAL DESIGN
A point-based rating system that evaluates environmental performance from a whole building perspective

12 indoor environmental quality.
What is LEED? USGBC definition: LEED promotes a whole-building approach to sustainability by recognizing performance in five key areas of human and environmental health: sustainable site development, water savings, energy efficiency, materials selection, and indoor environmental quality. 1

14 What is LEED? Buildings become certified Professionals become
accredited Products are never LEED or USGBC certified

15 Why was LEED created? Facilitate positive results for the environment, occupant health and financial return Prevent “greenwashing” Promote whole-building, integrated design processes Recognize leaders Stimulate green competition Raise consumer awareness Transform the marketplace!

16 What is the US Green Building Council?
The U.S. Green Building Council is the building industry’s only balanced non-profit consensus coalition promoting the understanding, development and accelerated implementation of green building policies, programs, technologies, standards, and design, operations and maintenance practices.

17 What is the Green Building Certification Institute?
GBCI was created to administer certification and credentialing programs related to green building practice and to ensure that the LEED Accredited Professional (LEED AP) program continues to be developed in accordance with best practices for credentialing programs. As of April 27, 2009, GBCI administers the LEED project registration and certification and the LEED Professional credentialing processes.

18 USGBC and GBCI Structure
USGBC is responsible for: Developing the LEED rating system Producing the LEED reference guides Developing and offering educational programs on the LEED rating system GBCI has two roles: LEED credentialing program Building certification

19 LEED Committees LEED rating systems are developed by USGBC staff and volunteer committees. Volunteers are all members of USGBC and represent a wide variety of building industry professions. **The LEED Steering Committee (LSC) oversees the development of the rating systems and acts as the governing body of all LEED committees. The Steering Committee enforces LEED direction and policy and delegates responsibility to the committees. If approved, the rating system is published and implemented. If it fails, it may go back to the Steering Committee and TAGs for further revision and may be considered again later.

20 LEED Committees Implementation Advisory Committee – Advises on the scope, content and rigor of technical resources and tools supporting LEED programs, with the goal of maintaining LEED's integrity while also providing an effective, predictable and satisfying LEED customer engagement. Market Advisory Committee - Advises on market transformation aspects of LEED in collaboration with USGBC staff, to ensure that LEED maintains leadership and continues to respond to the markets.

21 LEED Committees Technical Committee – Optimizes LEED's technical effectiveness and scientific validity across LEED credit categories and manages the work of the TAGs. Technical and Scientific Advisory Committee – Provides support for each of the LEED products and advice on topics as assigned by the LSC and the USGBC Board of Directors. **Rating System Committees – Responsible for the development and implementation of LEED credits for a specific building type or market sector. These committees are disbanded when the rating system is approved. If approved, the rating system is published and implemented. If it fails, it may go back to the Steering Committee and TAGs for further revision and may be considered again later.

22 LEED Committees **Technical Advisory Groups
Focus on specific practice areas and are involved with all the credits in their field across the rating systems. The TAGs are responsible for writing sections of new rating systems which are compiled into a draft version for public comment. The TAGs respond to Credit interpretation Requests (CIRS) TAGs also maintain technical rigor and consistency in the development of LEED credits If approved, the rating system is published and implemented. If it fails, it may go back to the Steering Committee and TAGs for further revision and may be considered again later.

23 How are the Rating Systems developed?
The draft is published on the USGBC website, and members are invited to review and comment, generally for 30 to 60 days. USGBC compiles the comments and refers them back to the LEED Steering Committee, which distributes to the TAGs for revision or further analysis. A second draft is posted for a 15-day comment period, and additional changes are made. The rating system is then “balloted,” and all USGBC members can vote for or against approval. A two-thirds affirmative vote is required.

24 GBCI Logos GBCI logo can be used to indicate sponsorship, accompany text about the corresponding organization or be used on a webpage as a link to GBCI homepage. LEED AP logo, LEED Green Associate logo and LEED AP Specialty logos are used to indicate achievement of credential or to accompany text about the corresponding credential.

25 USGBC Logos USGBC logo can be used to indicate sponsorship, accompany text about the corresponding organization or be used on a webpage as a link to USGBC homepage. USGBC member logo can be used by any member in good standing on business/marketing materials, or as link to USGBC homepage.

26 USGBC Logos LEED for Homes logo can be used by projects (on-site signage, marketing and other materials) seeking certification if it has received a preliminary rating. Also can be used as a link to the LEED for Homes homepage. LEED certification marks (certified, silver, gold, platinum) are used to promote certified projects. USBGC chapter logo should always be used with the name of the chapter.

27 USGBC Logos USGBC Education Provider Program (EPP) logo may be used by chapters and organizations participating in the EPP, and it can also be used to link to the EPP homepage. Greenbuild logo may be used for the promotion of the Greenbuild International Conference & Expo and to link to the Greenbuild homepage. NOTE: For both GBCI and USGBC logos, the entire logo including ® or™ must be used, and a notice of GBCI or USGBC ownership included. Logos should be taken from files prepared by GBCI and USGBC. The corresponding GBCI or USGBC department must authorize logo use.

28 Levels of LEED Certification
Four levels of LEED Certification: Certified = points, 40-50% of core credits Silver = points, 50-60% of core credits Gold = points, 60-80% of core credits Platinum = points, 80% or more of core credits

30 Cost of LEED Davis Langdon 2006 study Cost of Green Revisited: Reexamining the Feasibility and Cost Impact of Sustainable Design in the Light of Increased Market Adoption found “there is no significant difference in average cost for green buildings as compared to non-green buildings.”

31 Cost of LEED The Urban Green Council's recent study, "Cost of Green in NYC," surveyed 107 properties, including 38 multi-family high-rises, pursuing LEED certification. The study found no statistically significant difference in construction cost between LEED and non-LEED projects. Construction costs in the LEED high-rises came out to around $440 per square foot, while the non-green group averaged $436 per square foot. Luxury with renter reaping benefits of energy efficiency/developer can command higher rents

32 LEEDuser: “The Cost of LEED” Report
Earning a LEED certification for a project involves several different types of costs, and you have to consider each separately to get an accurate picture. Let’s envision the cost of LEED as an inverted pyramid with five levels from bottom to top. The bottom level is both the smallest (in size and cost) and the top level is potentially the biggest, but also a place where you have a lot of leeway. We’ll start at the bottom. The fees Cost of documentation time and effort Cost of extra research and design The cost of commissioning and modeling for compliance Costs of construction Purchase the report at

33 LEED 2009, composed of LEED rating system updates/revisions
What Is LEED v3? LEED v3 is the newest evolution of the LEED rating system. It was launched on April 27, LEED v3 encompasses three components: LEED 2009, composed of LEED rating system updates/revisions Revision and evolution of LEED certification process LEED Online v3 LEED Online v3 only available to LEED 2009 projects Under LEED v3, projects seeking certification will now be reviewed by a third-party certification body that is assigned at the time of registration.

34 What Is LEED 2009? LEED 2009 aligns five of the rating systems—NC, CS and Schools (now BD+C), CI (now ID+C) and OM (now EB O+M). All ratings in these five ratings systems are based on a 110-point system—100 points plus 10 potential bonus points. USGBC is now accepting comments to the 1st draft of the revised Rating System due out in 2012. LEED 2009 now includes Minimum Program Requirements (MPRs) that describe eligibility for each rating system: Comply with environmental laws Be a complete, permanent building or space Use a reasonable site boundary Comply with minimum floor area requirements Comply with minimum occupancy rates Commit to sharing whole-building energy & water usage data Comply with a minimum building area to site area ratio

35 What Is LEED 2009?

36 1) LEED Prerequisite/Credit Alignment and Harmonization
What Is LEED 2009? LEED 2009 changes include: 1) LEED Prerequisite/Credit Alignment and Harmonization 2) Predictable Development Cycle 3) Transparent Environmental/Human Impact Credit Weighting 4) Regionalization Credits and prerequisites have been consolidated and aligned, drawing on their most effective common denominators, so that credits and prerequisites are consistent across all LEED 2009 rating systems. Necessary precedent-setting and clarifying information from Credit Interpretation Rulings (CIRs) were incorporated into the rating systems. Credits will now have different weightings depending on their ability to impact different environmental and human health concerns. With revised credit weightings, LEED now awards more points for strategies that will have greater positive impacts on what matters most – energy efficiency and CO2 reductions.

37 LEED Prerequisite/Credit Alignment and Harmonization
Credits and prerequisites have been consolidated and aligned, drawing on their most effective common denominators, so that they’re consistent across all LEED 2009 rating systems. Necessary precedent-setting and clarifying information from Credit Interpretation Rulings (CIRs) were incorporated into the rating systems. LEED for Homes and LEED for Neighborhood Development were not changed under LEED 2009. ALL applicable ratings systems now require Environmental Tobacco Smoke Control and Fundamental Commissioning. Differences exist only where necessary to address specific market needs.

38 Transparent Environmental/Human Impact Credit Weighting
Credits now have different weightings depending on their ability to impact different environmental and human health concerns. More points are awarded for strategies that have greater positive impacts on what matters most – energy efficiency and CO2 reductions. Impact of each credit was evaluated using a complex credit-weighting tool developed by USGBC. The analysis combines information about each credit and its corresponding activity group with information about the credit’s impact categories as established by the National Institute of Standards and Technology’s Tool for the Reduction and Assessment of Chemical and other Environmental Impacts (TRACI).

39 Transparent Environmental/Human Impact Credit Weighting
In LEED 2009, more points are awarded in the Energy & Atmosphere, Water Efficiency and Sustainable Sites categories than in v2.2, and fewer points are awarded in Materials & Resources and Indoor Environmental Quality. Each credit was evaluated against a list of 13 environmental impact categories, including climate change, indoor environmental quality, resource depletion and water intake, among many others. The impact categories were prioritized, and credits were assigned a value based on how they contributed to mitigating each impact. The result revealed each credit’s portion of the big picture, giving the most value to credits that have the highest potential for making the biggest change.

40 Regionalization USGBC’s regional councils, chapters and affiliates worked to identify regionally specific environmental issues and prioritize six LEED credits for the region. Projects can receive up to four extra points (one point per credit) for earning the priority credits. Examples: Urban Florida: SSc5.2, MRc1.1, WEc2, EAc1, MRc5, and EQc8.1, to incentivize (among other things) decreased reliance on fossil fuels, reuse of existing building stock, decreased reliance on insufficient municipal wastewater plants, and utilization of abundant local sunshine. Rural Michigan: SSc1, SSc6.1, SSc6.2, SSc8, MRc5.2, and EAc2, to incentivize (among other things) the preservation of prime agricultural land, reduction of light trespass into neighboring natural habitats, and minimizing the amount and improving the quality of stormwater into the Great Lakes.

41 Regionalization Examples: Urban Florida: SSc5.2, MRc1.1, WEc2, EAc1, MRc5, and EQc8.1, to incentivize (among other things) decreased reliance on fossil fuels, reuse of existing building stock, decreased reliance on insufficient municipal wastewater plants, and utilization of abundant local sunshine.

42 LEED Minimum Program Requirements
LEED 2009 now includes Minimum Program Requirements (MPRs) that each project must adhere to: Comply with environmental laws. Be a complete, permanent building or space. Use a reasonable site boundary. Comply with minimum FTE & floor area requirements.

43 LEED Minimum Program Requirements
5) Comply with minimum occupancy rates (O&M) 6) Commit to sharing whole-building energy & water usage data 7) Comply with a minimum building area to site area ratio

68 Indoor Environmental Quality
LEED 2009 Credit Categories Water Efficiency Sustainable Sites Energy & Atmosphere Materials & Resources Indoor Environmental Quality Innovation & Design Process All of the LEED 2009 rating systems (NC, CI, CS, EB O&M, Schools) share the same six credit categories. ID is known as Innovation in Operations in LEED-EBOM.

69 Indoor Environmental Quality
The LEED Credit Categories Water Efficiency Sustainable Sites Energy & Atmosphere Materials & Resources Indoor Environmental Quality Innovation & Design Process Submittals Requirements Intent Technologies & Strategies

70 All LEED rating systems include: Prerequisites
The LEED Credit Categories All LEED rating systems include: Prerequisites Core credits (SS, WE, EA, MR, IEQ) Innovation and Design (ID) credits Exemplary performance Innovative strategies (refer to USGBC Innovation in Design Credit Catalog) All LEED ratings systems require compliance with federal, state and local environmental laws and regulations; LEED certification can be revoked upon knowledge of noncompliance.

71 Innovation and Design credits
Total of 6 points can be awarded for Innovation and Design credits: ID Credits (1- 5 points) Up to 3 points may be earned for exemplary performance (surpassing established thresholds of LEED credits) Up to 5 points can be awarded for innovative strategies which demonstrate quantifiable environmental benefits – unique approaches not outlined in LEED program ID Credit 2- LEED Accredited Professional - 1 point Point awarded if you have a LEED AP as a principal participant on project team *NOTE: EBOM – called Innovation in Operations and LEED-H – called Innovation and Design Process

72 What is LEED NC? LEED for New Construction and Major Renovation (LEED NC) is the original and most popular LEED rating system. It was developed for commercial and institutional buildings (especially office buildings) but has been successfully applied to a variety of projects.

73 LEED NC Major renovation involves elements of: Significant building envelope modifications Major interior rehabilitation Major HVAC renovation

74 What is LEED CI? LEED for Commercial Interiors (LEED CI) is an alternative rating system to LEED NC. It was developed with office use, tenant fit-out projects in mind but has been successfully applied to a variety of interior construction projects.

75 *Individual apartments or condominiums cannot be certified
What types of projects use LEED CI? The official answer: According to the USGBC, LEED-CI is applicable to “tenant projects.” The USGBC then defines tenants as: “one that pays rent to occupy a building, an occupant who dwells in a place, and/or a holder of buildings such as ownership or lease.” The short answer: Almost any type of interior construction project that can meet the prerequisite and credit requirements. *Individual apartments or condominiums cannot be certified

76 This slide illustrates the applicability of LEED-CI within a building.

77 Notes from USGBC “•You can have a LEED-CI certified space on one floor
•Or on multiple floors for multiple tenants”

78 ? ? What types of projects use LEED CI?
The boundary lines between different LEED rating systems overlap at times. The USGBC states, “If more than one rating system applies, then it is up to the project team to decide which one to pursue. The project is a viable candidate…if it can meet all prerequisites and achieve the minimum points required in a given rating system.” ? ?

79 A few differences: LEED NC LEED CI VS Showdown: LEED NC vs. LEED CI
Must Involve an Existing Building Can Involve an Existing Building VS Involves Site Selection Involves Site Selection and Design Energy Model Usually Needed Energy Model Optional

80 A few differences: LEED NC LEED CI VS Showdown: LEED NC vs. LEED CI
Building Envelope Must Be Considered Building Envelope Can Be Ignored VS Furniture Can be Included in Calcs Office Furniture Must Be Included in Calcs More Materials & Indoor Environ. Quality Credits More Site, Water, and Energy Credits

81 What is LEED CS? LEED CI is complemented by a third rating system, LEED CS (Core and Shell.) LEED CS covers the design and construction of the building envelope, systems and core. LEED CS can only be used for projects where the owner will occupy less than 50% of the leasable square footage. It is advantageous (but not necessary) for a tenant considering LEED CI to choose a LEED certified base building.

82 LEED CS LEED CS is the only rating system under which a project can complete a precertification application. Precertification provides a great opportunity to market the proposed green elements of the project. The project team details the strategies that will be used to pursue certification. Once a successful preliminary review of the application has been made by GBCI, the project can advertise that it is pre-certified. Precertification does not guarantee certification, and the project must still fulfill the certification requirements.

83 Oregon Convention Center, Portland OR, LEED-EB Certified
What is LEED for EBOM? LEED for Existing Buildings: Operations and Maintenance (LEED EBOM) is targeted towards owners and operators and is applicable to building operations, processes, systems upgrades, and minor space use changes. Oregon Convention Center, Portland OR, LEED-EB Certified

84 LEED EBOM LEED EBOM is targeted at single buildings that are 100% owner-occupied, though multiple-building projects and single multi-tenant buildings can potentially qualify under certain conditions. LEED EBOM is a whole-building rating system; individual tenant spaces are ineligible. Adobe HQ, San Jose CA LEED-EB Platinum

85 LEED EBOM The entire floor area of the building must be included unless a portion is controlled by separate management. In that case, up to 10% of the floor area can be excluded. At least 75% of spaces within the building must be physically occupied for at least 1 year, with building systems functioning at normal capacity. LEED EBOM can be used for additions and alterations that affect the usable space in an existing building (upgrades to building systems that don’t alter usable space are considered maintenance and are not eligible).

86 LEED EBOM Additions/alterations must comply with the following: Alterations can affect no more than 50% of the total floor area and cause relocation of no more than 50% of occupants. Total floor area cannot be increased by more than 50%. More than one trade specialty must be included. Substantial changes must be made to at least one room. The work site must be isolated from occupants for the duration of construction. Additions must increase floor area by at least 5%.

87 LEED NC & CI LEED EBOM An Event An On-Going Process VS
LEED NC, CI vs. LEED EBOM LEED NC & CI LEED EBOM An Event An On-Going Process VS Design & Construction Life of Building Capital Budgets Operating Budgets

88 LEED EBOM A LEED EBOM project team is significantly different from a LEED NC, CI, CS or Schools project team. LEED EBOM team members generally include: Owner Facility manager Property manager Building engineer Groundskeeper

89 LEED EBOM As an alternative to using the standard LEED credit categories, LEED EBOM projects can regroup credits according to functional characteristics. Possible functional characteristic groups are: Administration Materials in Materials out Site management Green cleaning Occupant health and productivity Energy metrics Operational effectiveness

90 LEED EBOM Policy Model Many LEED EBOM credits require a policy to be written and put in place for future actions. All of the required policies must contain the following components of the policy model: Scope: The processes to which the policy applies Performance Metric: How performance will be measured or evaluated Goals: The sustainability goals for the building (note: high goals are encouraged, actual achievement is not required)

91 LEED EBOM Policy Model Procedures: Outline of strategies to meet the goals Responsible Party: Teams and individuals involved and their key tasks Time Period: Time period over which the policy applies

92 LEED EBOM Performance Period
The LEED EBOM Performance Period is the time frame within which all applicable policies, programs, and tracking systems must be in place and operational. Initial Application Performance Period: Minimum of 3 months for all applicable prerequisites and credits and 12 months for the energy performance credits (EA prerequisite 2 and EA credit 1). All performance periods must end within 1 week of each other (EAp2 and EAc1 notwithstanding).

93 LEED EBOM Recertification
LEED EBOM buildings must submit for recertification at least once every 5 years to maintain their LEED EBOM status. Many of the LEED EBOM credits require different submittals for initial certification and recertification. For example, for recertification you may be able to submit a signed statement declaring that there have been no changes to certain items.

94 LEED for Schools K-12 projects must use LEED for Schools Other educational projects, including college projects, can use LEED for Schools or LEED-NC LEED for Schools is applicable to both new construction and renovation projects LEED for Schools is very similar to LEED-NC but has two additional prerequisites: Environmental Site Assessment Minimum Acoustical Performance

95 LEED-ND includes five credit categories: Smart Location and Linkage
LEED for Neighborhood Development LEED-ND certifies new developments that take into account sustainability and community connectivity principles and encourage smart growth. The rating system is a joint effort of the USGBC, the Congress for New Urbanism and the Natural Resources Defense Council. LEED-ND includes five credit categories: Smart Location and Linkage Neighborhood Pattern and Design Green Infrastructure and Buildings Innovation and Design Process Regional Priority Credits

96 LEED for Homes LEED for Homes is used for single-family detached and low-rise (3 stories or under) multifamily properties. Owner or builder must work from the beginning of the project with a LEED for Homes provider to enter the program. LEED for Homes providers manage teams of green raters who perform inspections and field testing and verify that LEED for Homes requirements have been met.

97 Innovation and Design Process Locations and Linkages
LEED for Homes LEED H has the same credit categories as the LEED 2009 rating systems, along with credits in three additional categories: Innovation and Design Process Locations and Linkages Awareness and Education LEED H is based on a 136-point scale. LEED H includes a Home Size Adjustment provision that allows the number of points required for certification to be adjusted according to the size of the home and the number of bedrooms. Certified 45 pts Silver pts Gold pts Platinum 90 pts

98 Evaluation of durability risks
LEED for Homes LEED H includes a durability planning prerequisite that promotes high performance of the building enclosure and its components and systems through appropriate design, materials selection and construction practices. The durability plan must include the following: Evaluation of durability risks Incorporation of durability strategies into design Implementation of durability strategies into construction Third-party inspection of the implemented durability features

99 LEED Portfolio Program
Goals of the Portfolio Program are to: Offer a volume certification path Provide a streamlined certification process for large-scale development Foster a network of investors, developers and owners committed to systemically greening their building portfolios Support participating organizations in fulfilling their sustainability commitments by providing solid performance metrics
