Rating Systems

What is LEED?

LEADERSHIP inENERGY andENVIRONMENTALDESIGN

A point-based rating system that evaluates environmental performance from a whole building perspective

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.

What is LEED?

What is LEED?• Buildings become certified

• Professionals become accredited

• Products are never LEED or USGBC certified

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!

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.www.usgbc.org

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.

USGBC and GBCI Structure

USGBC is responsible for:1) Developing the LEED rating system2) Producing the LEED reference guides3) Developing and offering educational programs on

the LEED rating system

GBCI has two roles:4) LEED credentialing program5) Building certification

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.

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.

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.

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

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.

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.

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. The logo may be used on packaging as long as terms and conditions in the logo guidelines are followed.

• LEED logo may be used to accompany text about the LEED program or to link to the LEED homepage.

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.

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.

Levels of LEED CertificationFour levels of LEED Certification:

• Certified = 40-49 points, 40-50% of core credits• Silver = 50-59 points, 50-60% of core credits• Gold = 60-79 points, 60-80% of core credits• Platinum = 80-110 points, 80% or more of core credits

Cost of LEEDDavis 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.”

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.

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.

1. The fees2. Cost of documentation time and effort3. Cost of extra research and design4. The cost of commissioning and modeling for compliance5. Costs of construction

LEED v3 is the newest evolution of the LEED rating system. It was launched on April 27, 2009. LEED v3 encompasses three components:

1. LEED 2009, composed of LEED rating system updates/revisions

2. Revision and evolution of LEED certification process3. LEED Online v3

What Is LEED v3?

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.

What Is LEED 2009?

What Is LEED 2009?

LEED 2009 changes include:

1) LEED Prerequisite/Credit Alignment and Harmonization2) Predictable Development Cycle3) Transparent Environmental/Human Impact Credit

Weighting4) Regionalization

What Is LEED 2009?

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.

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.

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.

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.

Regionalization

LEED Minimum Program Requirements

LEED 2009 now includes Minimum Program Requirements (MPRs) that each project must adhere to:

1) Comply with environmental laws.

2) Be a complete, permanent building or space.

3) Use a reasonable site boundary.

4) Comply with minimum FTE & floor area requirements.

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

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.

What is LEED NC?

Major renovation involves elements of:

• Significant building envelope modifications• Major interior rehabilitation• Major HVAC renovation

LEED NC

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.

What is 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

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.”

Building Envelope Must Be Considered

Building Envelope Can Be Ignored

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.

What is 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.

LEED CS

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.

What is LEED for EBOM?

Oregon Convention Center, Portland OR, LEED-EB Certified

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.

LEED EBOM

Adobe HQ, San Jose CALEED-EB Platinum

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).

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%.

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

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

LEED EBOM

• 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:

1. Scope: The processes to which the policy applies

2. Performance Metric: How performance will be measured or evaluated

3. Goals: The sustainability goals for the building (note: high goals are encouraged, actual achievement is not required)

LEED EBOM Policy Model

4. Procedures: Outline of strategies to meet the goals

5. Responsible Party: Teams and individuals involved and their key tasks

6. Time Period: Time period over which the policy applies

LEED EBOM Policy Model

• 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).

LEED EBOM Performance Period

• 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.

LEED EBOM Recertification

• 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

• 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:

1) Environmental Site Assessment2) Minimum Acoustical Performance

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:1) Smart Location and Linkage2) Neighborhood Pattern and Design3) Green Infrastructure and Buildings4) Innovation and Design Process5) Regional Priority Credits

• 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.

LEED for Homes

• LEED H has the same credit categories as the LEED 2009 rating systems, along with credits in three additional categories:

1) Innovation and Design Process2) Locations and Linkages3) 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.

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

LEED for Homes

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
