Item Summa /Recommendation:
SECOND READING/PUBLIC HEARING
The attached Ordinance proposes a Leadership in Energy and Environment Design (LEED) system for
buildings in the City of Miami Beach. LEED is a building rating system which recognizes and encourages
sustainable/green building and development practices. The LEED rating and certification system is
intended to enhance energy conservation, encourage reuse and use of recycled materials and encourage
operating practices that are environmentally friendly.
The LEED building rating system was developed bythe United States Green Building Council (USGBC) in
1998.
The Ordinance would establish a voluntary LEED Building Rating System for private development.
The Ordinance language mirrors an existing requirement in Section 255.2575, Florida Statutes (2008) for
City buildings that all new municipal buildings for which design began after July 1, 2008 be LEED certified.
The Ordinance provides for incentives both in terms of the time associated with processing an application
for green buildings in the City's permitting review and approval process, and also potentially financial
incentives.
The LEED certification process for construction is a recognized and objective tool to assess a project's
compliance with established enhanced environmental practices. Buildings that are LEED certified are
ultimately more friendly to the environment and in the long-term will benefit the overall environmental
health of the community through energy waste, and water consumption reduction. As there is typically a
reduction in operating expenses associated with LEED certified buildings, the investment in a building to
have an achieved LEED certification is also recovered. Through the provision of both time and possibly
monetary incentives, the recommended model for the City of a voluntary program is a good starting point
for Cit en a ement in environmentall enhanced buildin s.

Approve the Ordinance.
BACKGROUND
The attached Ordinance proposes adopting a Leadership in Energy and Environment
Design (LEED) system for buildings in the City of Miami Beach. LEED is a building rating
system which recognizes and encourages sustainable/green building development,
construction and management practices. The LEED rating and certification system is
intended to enhance energy conservation, encourage use of recycled materials and
encourage operating practices that are environmentally friendly.
The LEED building rating system was developed by the United States Green Building
Council (USGBC) in 1998 and has systematically evolved and improved to an internationally
recognized standard to encourage and assess the actual performance of green building
development.
The USGBC is a national organization of volunteers founded to represent the building
industry on environmental building matters. Information about the USGBC is found in Exhibit
1.
In order to participate in the LEED Building Rating System, a building owner must make an
application to the USGBC for participation. The applicant pays a registration and review fee
of approximately $3,000.00 to the USGBC for the assessment of the building project and the
certification completed at the end of the project. The LEED Building Rating System is
organized around six different areas for which a building can achieve points toward a
certification. LEED certification comes in basic certification, silver, gold and platinum levels.
The six project areas are found in the project checklist, Exhibit 2. This exhibit depicts the
points associated with the rating areas of: sustainable site, water efficiency, energy and the
atmosphere, material and resources, indoor environmental quality, and innovation and
design processes. In the ranking process, a total of 69 points is the maximum that can be
achieved and the minimum to achieve the silver level is 33 points.
Each project is reviewed by the USGBC to determine which of the credits or project points
are appropriate and achievable for the specific building. These agreed upon credit and point
areas are then pursued by the builder/developer in the design, construction and
management phases. At the conclusion of the building process and the actual
commencement of operation of the building, the building is reassessed by the USGBC (or a
certified reviewer on its behalf) to determine if the points and credit areas have actually been
accomplished.
As the project checklist indicates, there are a number of different possible credits within the
general rating areas of the LEED certification. For example: in the area of sustainable sites
there are fourteen (14) possible points that can be achieved by a building/development.
Generally, each specific credit area within the more general rating area provides a
builder/developer several different methods to achieve the credit and earn the appropriate
point. Exhibit 3 indicates one (1) typical credit area, storm water design, that illustrates two
(2) different options for abuilding/developer to achieve the credit associated within this
specific area. The credit criteria are very specific as to how the credit is calculated and the
nature of the documentation that is required in order for the builder/developer to achieve
compliance for this particular credit.
Achieving compliance with LEED standards typically costs abuilder/developer more than
ordinary design and construction. While there is no precise measurement, industry
estimates are that 5% to 7% in additional costs may be experienced in making a building
LEED certified. By the same token, buildings that are LEED certified typically consume less
energy and therefore over time are less expensive to operate than conventional
construction.
LEED Ordinance Overview
The attached Ordinance would establish a voluntary LEED Building Rating System for
private development. While mandatory LEED participation was discussed by the Land Use
and Development Committee, it was determined that the initial effort of the City would be
more positive and less complicated if a voluntary participation based system was
implemented.
As the system is voluntary there is no minimum building size for which the LEED program
would be made available. Any building project, residential or commercial, substantial
renovation or new construction would be eligible to participate in the LEED certification
process. The voluntary approach is more expansive and more inclusive of a range of
2
buildings in the City than a mandatory program would allow. In a mandatory participation
approach typically single family residences and smaller projects are excluded because of the
costs of compliance and/or participation. In the voluntary model each building/developer can
determine if they wish to participate as their specific project allows.
The Ordinance language mirrors an existing requirement in Section 255.2575, Florida
Statutes (2008) for City buildings that all new municipal buildings for which design began
after July 1, 2008 be LEED certified. LEED certification for substantial renovations of
municipal buildings is not required by statute and thus not part of the Ordinance.
A modification made by the City Commission at 1St Reading was to change the level of LEED
certification from the lowest certified level, to the second or silver certification level.
The key to the City's LEED Ordinance and its success on a voluntary basis is found in the
different incentives that are built into the Ordinance. The Ordinance provides for incentives
both in terms of the time associated with processing an application for green buildings in the
City's permitting review and approval process, and also potentially financial incentives. Each
of these two incentive areas will be addressed separately.
LEED Time Incentives
The LEED Ordinance anticipates that individuals who elect to participate in the program will
be eligible to have prioritized review in the Building development permitting process. This
was a change made by the City Commission at 1S Reading of the LEED Ordinance. The
original Ordinance created a priority review through the entire Land Use Board approval
process. By providing this prioritization during the review process, any particular project may
save weeks in processing time as opposed to traditional processing in the queue with other
projects and developments.
In order to ensure that this time incentive is not abused, the Ordinance also requires that in
order to receive incentives each building/developer post a bond. The bond is intended to
ensure that a project does not take advantage of the time incentive or the financial incentive,
if appropriate, and then fail to achieve the LEED certification at the end of the process.
The Land Use and Development Committee discussed at some length the appropriate level
of bond amount in order to assure that the incentives offered are not abused. Initial drafts of
the Ordinance contained a percentage of construction (3% for example). At the 1St Reading,
the City Commission agreed that a 1 % of construction cost bond would be appropriate,
which is reflected now in the Ordinance.
LEED Financial Incentives
The attached Ordinance also makes provisions for a financial incentive associated with
achieving the LEED certification. A variety of different options were discussed by the Land
Use and Development Committee and the Administration. No consensus was achieved by
the Land Use and Development Committee and the Administration was asked to propose a
model which could be discussed at the full Commission level.
Original discussions revolved around either providing a rebate of some percent of the
building permit fees and/or creating a fund through a surcharge mechanism from which a
financial incentive could be provided to a builder/developer. In the Administration's
assessment of the use of building fees, it has been deemed that a rebate of those fees is not
allowed to achieve an incentive as anticipated in the LEED program. Building fees are
specifically earmarked to provide payment to the City for services directly related to the
building inspection and review process. LEED, while a worthy and desirable community
goal, is not an eligible subject matter for use of building permit fees as it would require one
project to subsidize another project.
3
The idea of imposing a surcharge fee on the building process was also discarded by the
Administration as unfeasible, as it would be difficult to document the basis for the fee. The
economic disincentive associated with a surcharge was not seen as desirable, particularly in
these economic conditions.
The Ordinance proposes a model which is intended to specifically limit the City's exposure
for annual expenditures in achieving the goals associated with the LEED Ordinance. The
City Commission, by annual resolution in the budget process, would appropriate a precise
amount of funds that would be allocated and available for financial incentives for projects
that achieve a LEED Certification. As such, the specific financial impact of the Ordinance is
established and known by the City Commission in each budget cycle. As the level of annual
expenditure is proposed to be reviewed and assessed in the budget cycle, the City
Commission also has the opportunity of comparing the priority of a LEED incentive
expenditure with other priorities which will be contained in the annual budget.
The financial incentives shown in the ordinance are intended to help offset the cost of
application and review for LEED certification and a percentage of added costs incurred in
building to LEED standards.
Application and review costs for LEED certification are approximately $3,000 per project.
This is inclusive of the registration design and construction review costs that are charged by
the USBGC.
Projects that pursue LEED certification typically incur an increase in construction costs of 5-
7%. In order to help offset some of this incremental cost increase, a grant of up to 5% of the
added cost is suggested. For a project costing $3.5 million, the cost of LEED certification
may be approximately $200,000. With the financial incentive of 5%, the project would be
eligible to receive $10,000 as a cost offset. When added to the application and review
incentive, the project ($3.5 million construction cost example) would be eligible to receive
$13,000.
It is also suggested that a maximum incentive of 20% of the total annual appropriation be
established for any one project. This limit would ensure that no one project would consume
the resources available in a given year.
It is important to note that in the event the City Commission does not choose to allocate the
monetary resources in a fiscal year, the LEED certification and incentive process can still
function solely on the basis of the time incentive that is provided within the Ordinance. While
the financial incentive is also helpful, as indicated earlier, for buildings that do become LEED
certified, over the long term operational expenses are typically less than normal buildings
and the investment costs associated with accomplishing a LEED certification will be earned
back over time.
In this and perhaps several fiscal years, it may be unrealistic to expect to be able to allocate
funds to the LEED program financial incentives. As energy and environmental related
grant funds become available in the future, that may be the best or a more likely source of
funds for the program. The current economic stimulus package anticipates some funding for
energy conservation and green related projects. While the initial round of funding is
intended to be used quickly, subsequent funding rounds may be available for the City to
secure funds for the financial component of the LEED incentives.
Other Implementation Issues
The Administration has reviewed the implementation of this Ordinance, and believes that
there are only incremental costs associated with implementation. The building development
4
review process functions largely the same in a LEED eligible project in terms of the amount
of time or attention that is paid to the project by the Administrative staff. The amount of
design and plan review and building inspection remains relatively unchanged for a LEED
project.
One item, which is a cost of implementation and required in the Ordinance, is to have
qualified staff in the Building, Planning and Public Works Departments to assess and to
assist with the project developments. This is an incremental and annual cost. To date the
Building Department has already has four (4) people in training, one of which has been
LEED accredited. The Public Works Department has two (2) persons undergoing the
training and the Planning Department is anticipated to have staff trained in the near future.
CONCLUSION
The LEED certification process for construction is a recognized and objective tool to assess
a project's compliance with established enhanced environmental practices. Buildings that
are LEED certified are ultimately more friendly to the environment and in the long-term will
benefit the overall environmental health of the community through energy, waste, and water
consumption reductions. As there is typically a reduction in operating expenses associated
with LEED certified buildings, the investment in a building to have an achieved LEED
certification is also recovered. Through the provision of both time and possibly monetary
incentives, the recommended model for the City of a voluntary program is a good starting
point for City engagement in environmentally enhanced buildings. At some point in the
future, the City Commission may wish to consider making the program mandatory as
sustainable development practices become more wide spread and easier to achieve. The
Administration recommends approval of the Ordinance.

LEED is a third-party certification program and the nationally accepted
benchmark for the design, construction and operation of high performance
green buildings. LEED gives building owners and operators the tools they
need to have an immediate and measurable impact on their buildings'
pertormance. LEED promotes awhole-building approach to sustainability
by recognizing pertormance in five key areas of human and environmental
health: sustainable site development, water savings. energy efficiency,
materials selection and indoor environmental quality.
Wha uses LEED?
Architects, real estate professionals, facilfty managers, engineers, interior
designers, landscape architects, construction managers, lenders and
government officials all use LEED to help transform the built environment
to sustainability. State and local governments across the country are
adapting LEED for public-owned and public-funded buildings; there are
LEED initiatives in federal agencies, including the Departments of Defense
Agriculture. Energy, and State; and LEED projects are in progress in 41
different countries, including Canada. Brazil, Mexico and India.
How is LEED Developed?
LEED Rating Systems are developed through an open, consensus-based
process led by 3 LC c~~rwt mtt es. Each volunteer commdtee is composed
_..._
of a diverse group of practitioners and experts representing across-section
of the building and construction industry. The key elements of USGBC's
consensus process include a balanced and transparent committee
structure, technical advisory groups that ensure scientific consistency and
rigor, opportunities for stakeholder comrnent and review, member ballot of
new rating systems, and a fair and open appeals process.

The U.S. Green Building Council (USGBC) is a 501(c)(3) nonprofit membership organization with a vision of a
sustainable built environment within a generation. Its membership includes corporations, builders, universities,
government agencies, and other nonprofit organizations. USGBC is dedicated to expanding green building
practices and education, and its LEED®(Leadership in Energy and Environmental Design) Green Building Rating

The Leadership in Energy and Environmental Design (LEED) Green Building Rating System is a voluntary,
consensus-based national rating system for developing high-performance, sustainable buildings. LEED addresses
all building types and emphasizes state-of-the-art strategies in five areas: sustainable site development, water
savings, energy efficiency, materials and resources selection, and indoor environmental quality.
LEES
AP
LEED Accredited Professionals (LEED APs) have demonstrated a thorough understanding of green building
techniques, the LEED Green Building Rating System, and the certification process. The LEED AP program is
administered by the Green Building Certification Institute (GBCI), which was established with the support of
USGBC to allow for objective, balanced management of the credentialing program.
Introduction
U.S. Green Building Council
I. Why Make Your Building
Green?
The environmental impact of the build-
ing design, construction and operation
industry is significant. Buildings annually
consume more than 30% of the total
energy and more than 60% of the electric-
ity used in the U.S. Each day five billion
gallons of potable water is used soley to
flush toilets. A typical North American
commercial construction project ger.Pr-
ates up to 2.5 pounds of solid waste per
square foot of completed floor space.
Development shifts land usage away from
natural, biologically-diverse habitats to
hardscape that is impervious and devoid
of biodiversiry. The far reaching influence
of the built environment necessitates ac-
tion to reduce its impact.
Green building practices can substantially
reduce or eliminate negative environmen-
tal impacts and improve existing unsus-
tainable design, construction and opera-
tionalpractices. As anadded benefit, green
design measures reduce operating costs,
enhance building marketability, increase
worker productivity, and reduce potential
liability resulting from indoor air quality
problems. For example, energy efficiency
measures have reduced operating expenses
of the Denver Dry Goods building by ap-
proximately $75,000 per year. Students in
day-lit schools in North Carolina consis-
tently score higher on tests than students
in schools using conventional lighting
fixtures. Studies of workers in green build-
ings reported productivity gains of up to
16%, including reductions in absentee-
ism and improved work quality, based
on "people-friendl}'" green design. At a
grocery store in Spokane, Washington,
waste management costs were reduced by
56°io and 48 tons of waste was recycled
during construction. In other words, green
design has environmental, economic and
social elements that benefit all building
stakeholders, including owners, occupants
and the general public.
II. LEED®Green Building
Rating System
A. History of LEED®
The first LEED (Leadership in Energy
and Environmental Design) Pilot Project
Program following the formation of the
U.S. Green Building Council (USGBC)
in 1993, the membership quickly realized
that a priority for the sustainable building
industry was to have a system to define
and measure "green buildings." The
USGBC began to research existing green
building metrics and rating systems. Less
than a year after formation, the member-
ship followed up on the initial findings
with the establishment of a committee
to focus solely on this topic. The diverse
initial composition of the committee
included architects, realtors, 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 Membership
Summit in August 1998. After extensive
modifications, the LEED Green Building
Rating System Version 2.0 was released in
March 2000. This rating system is now
called the LEED Green Building Rating
System for New Commercial Construc-
tion and Major Renovations, or LEED
for New Construction.
As LEED has evolved and matured, the
program has undertaken new initiatives.
In addition to a rating system specifi-
cally devoted to building operational and

products serving specific market sectors.
B. Features of LEED®
The LEED Green Building Rating System
is a voluntary, consensus-based, market-
driven building rating system based on
existing proven technology. It evaluates
environmental performance from a whole
building perspective over a building's life
cycle, providing a definitive standard for
what constitutes a "green building." The
development of the LEED Green Build-
ing Rating System was initiated by the
USGBC Membership, representing all
segments of the building industry and has
been open to public scrutiny.
The rating system is organized into five
environmental ca~egories:;~ Sustainable
Sites, Water Efficiency, Energy & Atmo-
sphere, Materials & Resources, and Indoor
Environmental Quality. An additional
category, Innovation & Design Process,
addresses sustainable building expertise as
well as design measures not covered under
the five environmental categories.
LEED is a measurement system designed
for rating new and existing commercial,
institutional and residential buildings. It
is based on accepted energy and environ-
mental principles and strikes a balance
between known established practices and
emerging concepts.
It is aperformance-oriented system where
credits are earned for satisfying criterion
designed to address specific environmental
impacts inherent in the design, construc-
tion and operations and maintenance
of buildings. Different levels of green
building certification are awarded based
on the total credits earned. The system is
designed to be comprehensive in scope,
yet simple in operation.
C. The Future of LEED
The green design field is growing and
changing daily. Nev~~ technologies and
products are coming into the marketplace
and innovative designs are proving -their
effectiveness. Therefore, the Rating Sys-
tem and the Reference Guide will evolve
as well. Teams wishing to certify with
LEED should note that they will need
to comply with the version of the rating
system that is current at the time of their
registration.
USGBC will highlight new developments
on its Web site on a continuous basis at
www.us bc.org.
III. LEED for New Construction
Overview and Process
The LEED Green Building Rating System
for New Construction and Major Renova-
tion (formerly referred to as LEED-NC)
provides a set of performance standards
for certifying the design and construction
phases of commercial, institutional build-
ings, and high-rise residential buildings.
The specific credits in the rating system
provide guidelines for the design and
construction of buildings of all sizes in
both the public and private sectors. The
intent of LEED for New Construction
is to assist in the creation of high perfor-
mance, healthful, durable, affordable and
environmentally sound commercial and
institutional buildings.
LEED for New Construction addresses:
^ Sustainable Sites
^ Water Efficiency
^ Energy & Atmosphere
^ Materials & Resources
^ Indoor Environmental Quality
^ Innovation in Design
A. When to Use LEED for New
Construction
LEED for New Construction was de-
signed primarily for new commercial
office buildings, but it has been applied
to many other building types by LEED
practitioners. All commercial buildings,
as defined by standard building codes,
are eligible for certification as a LEED for
New Construction building. Commercial
occupancies include (but are not limited
to) offices, retail and service establish-
ments, institutional buildings (libraries,
schools, museums, churches, etc.), hotels
and residential buildings of four or more
habitable stories.
LEED for New Construction. addresses
design and construction activities for
both new buildings and major renova-
tions of existing buildings. The LEED
Green Building Rating System for Ex-
isting Buildings is designed to address
operational and maintenance issues of
working buildings. Therefore, if you are
performing a major renovation on an
existing building, LEED for New Con-
struction is the most appropriate rating
system for your project. If however, your
project scope does not involve significant
design and construction activities and fo-
cuses more on O&M activities, LEED for
Existing Buildings is the most appropriate
tool for your project. As a general rule
of thumb, a major renovation involves
elements of major HVAC renovation,
significant envelope modifications and
major interior rehabilitation.
Many projects will cleanly .and clearly
fit the defined scope of only one LEED
Rating System product. For other proj-
ects, two or more LEED Rating System
products may be applicable. USGBC
encourages the project team td tally a
potential point total using the Rating
System checklists for all possibilities. 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
one Rating System applies, then it is up
to the project team to decide which one
to pursue. For assistance in choosing the
most appropriate LEED Rating System,
_ please e-mail IeedinfoCusgbc.org.
B. LEED for New Construction
Registration
Project teams interested in obtaining
LEED Certification for their project must
first register this intent with USGBC. Pro j-
ects can be registered on the USGBC Web
site (www.us~bc.or~) in the LEED section,
under Register Your Project. The Web site
includes information on registration costs
for USGBC member companies as well as
non-members. Registration is an important
step that establishes contact with USGBC
and provides access to LEED-Online soft-
ware tool, errata, critical communications
and other essential information.
About LEED-Online
As of January 2006, project teams pursu-
ing LEED for New Construction certifi-
cation under Version_2.2 are required to
use LEED-Online, which enables teams
to submit 100% of their documentation
online in an easy-to-use format. LEED-
Online stores all LEED information,
resources, and support in one centralized
location. LEED-Online enables team
members to upload credit templates,
track Credit Interpretation Requests
(CIRs), manage key project details, con-
tact customer service, and communicate
with reviewers throughout the design and
construction reviews.
C. Credit Interpretation Rulings
In some cases, the design team may en-
counter challenges in applying a LEED for
New Construction prerequisite or credit to
their particular project. These difficulties
arise from instances where the Reference
Guide does not sufficiently address a
specific issue or there is a special conflict
that requires resolution. To address such
issues, the USGBC has established the
LEED for New Construction Version
2.2 Credit Interpretation Ruling (CIR)
process (separate from the CIR page for
version 2.0 and 2.1 CIRs). See the LEED
for New Construction section of the
USGBC Web site for more information
LEED for New Construction Version 2.2
15
at www.usgbc.or~. Credit rulings posted
after the registration date may be applied
by the project team at their choosing
(exception: the project's own CIRs must
always be adhered to).
The Credit Interpretation process is sum-
marized as follows:
1. Project teams should review the CIR
webpage to read previously posted
credit interpretation requests and
USGBC responses. Many questions
can be resolved by reviewing existing
CIRs and the Reference Guide. Note
that CIRs for other rating systems
(LEED for Existing Buildings, LEED
for Commercial Interiors and past ver-
sions ofLEED for New Construction)
are not necessaril}~ applicable.
2. If no existing Credit Interpretation
Rulings are relevant'to the project, the
LEED project team should submit an
on-line credit interpretation request.
The description of the challenge en-
countered by the project team should
be brief but explicit; should be based
on prerequisite or credit information
found in the Rating System and Refer-
ence Guide; and should place a special
emphasis on the Intent of the prereq-
uisite or credit. If possible, the project
team should offer potential solutions to
the problem and solicit approval or re-
jection oftheir proposed interpretation.
Follo~~ the detailed instructions in the
"CIR Guidelines" document available
on the CIR Web page in the LEED
section of the USGBC Web site.
3. USGBC will rule on your request
electronically according to the
posted schedule, either through a
posting on the CIR Page or via e-mail
correspondence.
D. LEED for New Construction
Application
Once a project is registered, the project
design team begins to collect information
and perform calculations to satisfi~ the
prerequisite and credit submittal require-
ments. Since submittal documentation
should be gathered throughout design
and construction, it is helpful to designate
a LEED team leader who is responsible
for managing the compilation of this
information by the project team. Use the
LEED-Online Submittal Templates that
are provided through the LEED project
resources Web page located in the LEED
section of the USGBC Web site. These
templates contain embedded calculators,
and are instrumental in documenting
fulfillment of credit requirements and
prompting for correct and complete sup-
porting information.
Two-Phase Application
A new feature of LEED for New Con-
struction v2.2 is the option of splitting a
certification application into two phases.
Rather than submitting all documentation
for a project at the end of the construc-
tion phase, project teams will be able to
submit designated "design phase credits"
at the end of the design phase for review
by USGBC. Design phase credits are
those credits that USGBC can reasonably
adjudicate based on design phase docu-
mentation. For example, if a. project site
meets the LEED for New Construction
Sustainable Sites Credit 3: Brownfield Re-
development Requirements, USGBC can
assess the likelihood of the project achiev-
ing this credit prior to the completion of
construction. It is important to remember
that LEED credit is not awarded at the
design review stage. Project teams are noti-
fied ofthe likelihood that their project will
achieve a LEED credit if construction is
executed in accordance with design phase
plans. Projects must submit verification
that design elements were implemented
as planned after completion of construc-
tion. Alist of the potential design phase
credits can be found in the LEED section
of the USGBC Web site. Project teams are
allotted one design phase review. At the
completion of construction, the balance
of attempted credits, verification of design

phase credits, and additional documenta-
tion for any design phase credits that has
changed since the design phase review are
documented and submitted for USGBC
review. See below for more details regard-
ing the two-phase review.
E. Review and Certification
To earn LEED for New Construction
certification, the applicant project must
satisfy all of the prerequisites and a
minimum number of points to attain the
established LEED for New Construction
project ratings as listed below. Having
satisfied the basic prerequisites of the
program, applicant projects are then rated
according to their degree of compliance
within the rating system. All projects will
need to comply with the version of LEED
for Ne~~ Construction that is current at
the time of project registration.
Design Phase Review
Once USGBC has received your com-
plete design phase application and the
design phase fee (which is a portion of
the total certification fee), the USGBC
will formally rule on your application by
.designating each attempted credit as either
Anticipated or Denied. No certification
award will be given at this time, nor will
any credits be awarded. This process serves
to allow project teams the opportunity to
assess the likelihood of credit achievement,
and requires follow through to ensure the
design is executed in the construction
phase according to design specifications.
Construction Phase Review
At the completion of construction, the
project team will submit all attempted
credits for review. If the project team had
elected to have a design phase review and
any of the design phase Anticipated credits
have changed, additional documentation
must be submitted to substantiate contin-
ued compliance with credit requirements.
For design phase Anticipated. credits that
have not substantively changed, the project
team must submit a verification that the
design has been executed per requirements
in the construction phase. Once USGBC
has received the complete application and
fee (the remainder of the total certification
fee, if a design review has been conducted),
the USGBC will formally rule on your
full application. All applicant-verified
design phase credits that were designated
as Anticipated and have not changed since
the design phase review will be declared as
Achieved. All other credits will be desig-
nated aseither Achieved or Denied.
Appeals
Appeals may be filed either after the
design phase review or the final review.
Please see the LEED Certification Pro-
cess section (htt~//wwv~~.usgbc.or~/
Dis~layPage_aspx?CMSPageID=1497) of
the USGBC Web site for more informa-
tion on .appeals.
Fees
Certification fee information can be found
at the LEED Register your project page
of the web site: http://www.us bg_c.org_/
DisplayPage.aspx?CMSPa~eID=65 &.
USGBC will acknowledge receipt of your
application and proceed with application
review when all project documentation
has been submitted.
The LEED for Nev~~ Construction ratings
are awarded according to the following
scale-
^ Certified 26-32 points
^ Silver 33-38 points
^ Gold 39-51 points
^ Platinum 52-69 points
USGBC will recognize buildings that
achieve one of these rating levels with a
formal letter of certification and a mount-
able plaque.
F. Updates & Errata
This is the second edition of the LEED
for New Construction version 2.2 Refer-
ence Guide, dated September 2006. As
LEED for Ne~~ Construction continues
LEED for New Construction Version 2.2
17
to improve and evolve, updates and en-ata
will be made available to substitute and
augment the current material. USGBC
cannot be held liable for any criteria set
forth herein, which may not be appli-
cable to later versions of LEED for New
Construction. Updates and addenda will
be accumulated between revisions and
will be formally incorporated in major
revisions. In the interim between major
revisions, USGBC may use its consensus
process to clarify criteria.
When a project registers for certification,
the prerequisites, credits, errata, and credit
rulings current at the time of project regis-
tration will continue to guide the project
throughout its certification process.
IV. LEED for New Construction
Version 2.2 Reference Guide
The LEED for New Construction v2.2
Reference Guide is a supporting docu-
ment to the LEED Green Building Rating
System. The Guide is intended to assist
project teams in understanding LEED for
New Construction criteria and the bene-
fits of complying with each criterion. The
Guide includes examples of strategies that
can be used in each category, case studies
of buildings that have implemented these
strategies successfully, and additional
resources that will provide more infor-
mation. The guide does not provide an
exhaustive list of strategies for meeting
the criteria as subsequent strategies will
be developed and employed by designers
that satisfy the Intent of each credit. Nor
does it provide all of the information that
design teams need to determine the ap-
plicabilit}' of a credit to their project.
Prerequisite and Credit Format
Each prerequisite and credit is organized
in a standardized format for simplicity
and yuick reference. The first section
summarizes the key points regarding the
measure and includes the Intent, Require-
ments, and some Potential Technologies
& Strategies for achieving the credit. The
subsequent sections provide supportive
information to help interpret the measure,
examples, and links to various resources.
If your project team encounters an out-
of--date web link in the Reference Guide,
please go to the root Web site, which
should take the form of www.organization.

in an urban environment where water is
discharged to concrete channels and then
the ocean are different from the strategies
employed at an inland site that discharges
to a small stream and lake system.
The most effective method to minimize
stormwarer runoff volume is to reduce the
amount of impervious area. By reducing
impervious area, Stormwater ~infi-astruc-
ture can be minimized or deleted from the
`project. Strategies to minimize or mitigate
impervious surftces may include:
~J Smaller building footprint
.J Pen~ious paving materials
J Stormwater harvesting for reuse in
irri~~ation and/or buildings
J Gree^ roofs
J Bioswales/vegetated filter strips
~ Rerention ponds
J Clustering development to reduce
paved surfaces (roads, sidewalks. etc.)

Guidelines for Capturing and
Reusing Stormwater Runoff
Stormwater capnued (or harvesredj in
cisterns, rain barrels, or odler devices, is
a primary source of water in many parts
of the world. Stormwater should not be
used for potable needs if there arc sources
available that pose less risk ro public
health. However. harvested Stormwater
maybe used to reduce potable water needs
for uses such as landscape irri~acion, fire
suppression, toilet and urinal flushing,
and custodial uses.
Storage and reuse techniques range from
small-scale systems (.e.g., rain barrels) to
underground cisterns char may hold large
volumes of water. Whether large or small,
stormwarer harvesting sysrem designs
should consider the following:
] . Water need for the intended use-how
will the harvested water be used and
when will it be needed' For example,
if the water is used to irrigate land-
scaping for four summer months, the
amount of water needed and the how
often the storage unit will refill must
be considered. Usage requirements and
the expected volume and frequency of
rainfall must be determined.
2. Drawdown-storage system design
must provide for the use or release of
water between storm events for the de-
sign storage volume to be available.
3. Drainage Area-the size and nature
(e.g., percent imperviousness) of the
area draining to the storage system
determines how much runoff will be
available for harvesting.
4. Conveyance System-reused storm-
warer and gra~~vater systems must
not be connected to other domestic
or commercial potable ~~~ater systems.
Pipes and storage units should be
clearly marked (e.g., "Caution: Re-
claimed Water. Do Not Drink").
~. Pretreatment-screens or filters may
be used ar remove debris and sedi-
ment from runoff and to minimize
pollutants.
6. Pressurization-uses for harvested
rainwater may require pressurization.
For example, most irrigation systems
require a water pressure of at least 15
psi to function properly. Stored water
has a pressure of 0.43 psi per foot of
water elevation, and the water pres-
sure at the bottom of a ten-foot vault
would be 4.3 psi (10 ft. x 0.43 psi).
Pressurization (e.g.> a pump, pressure
tank and filter) costs more and creates
a more useable system.
The amount of runoff reduced by a
stormwater harvesting system may be
considered equal to its storage volume.
However, volume calculations must also
consider how often the system is emptied
and the interval between storm events.
Example:
Rainwater will be harvested from a 10,000
sq.ft. roof (100% imperviousness). The
system will be designed to capture the
runoff from 90% of the average annual
rainfall (1 inch of rainfall for humid wa-
tersheds). The volume of the proposed
storage system is the amount of runoff
captured (Vr), which is calculated below
in Equation 1:
Other design considerations -tank must
be emptied before subsequent storm
events. Use a tank that is 10 ft x 10 ft x
'~~' ' 8 ft deep -Total storage volume (VS) _
tt~~~ 800 cu.ft. Using a design storm interval
`~', of three days (72 hours), the drawdown
Equation 1
rate (Qt) is calculated below in Equa-
tion 2:
In this example, the captured rain must be
drained within 3 days or at a minimum
rate of 1.4 gpm for the tank to be emptied
for the next storm.
Different municipalities, state and lo-
cal governments have various design
requirements for capturing and reuse of
stormwater runoff. These requirements
range from where stormwater may be
captured and used to length of time
stormwater can be held in a cistern, ro
the type of water treatment required be-
fore reuse. Designers should check with
the governing administrative authority
to determine parameters which will af-
fect collection, use, and distribution of
captured stormwater.

Watershed Imperviousness (%)
Synergies and Trade-Offs
stormwater runoff is affected significantly
b~~ site topography, site design, and espe-
cialh~ quantity of impervious surface area
to support transportation amenit>~ design.
It may be possible to reuse storm~y~ater
for non-potable water purposes such as
flushing urinals and toilets, custodial ap-
plications, and building equipment uses.
1r is helpful to perform a water balance to
determine the estimated volumes of water
availafile for reuse. stormwater runoff
volumes can also be reduced by designing
the building with underground parking.
a strateg}- that alsv reduces heat island
effects. Pervious paving systems usually
have a limit on transportation loads and
may pose problems for wheelchair acces-
sibilir}~ and stroller mobility. If stormwater
volumes are treated on site, additional site
area ma>> need to be disturbed to construct
treatment ponds or underground facili-
ties. Application of green roofs reduces
stormwater volumes that may be intended
for collection and reuse for non-potable
applications.

Definitions
Impervious Surfaces promote runoff of
precipitation volumes instead of infiltra-
tioninto the subsurface. The impervious-
ness or degree of runoff potential can be
estimated for different surface materials.
Stormwater Runoff consists of water
volumes that are created during precipi-
tation events and flow over surfaces into
sewer systems or receiving waters. All
precipitation waters that leave project site
boundaries on the surface are considered
to be stormwater runoff volumes.
