Why LEED

Federal Energy and Sustainability

Laws/Regulations/Policies

► Energy Policy Act of 2005 (EPAct 05)

► Energy Independence and Security Act of 2007 (EISA

2007)

► High Performance and Sustainable Buildings (2006)

► Executive Order 13423: Strengthening Federal

Environmental, Energy and Transportation

Management (2007)

► High Performance and Sustainable Buildings (HPSB)

LEED SILVER CERTIFIED VS.

CERTIFIABLE

BUILDING STRONG®

LEED Silver “Certifiable”

Government Validation vs. GBCI Certification

USACE District is responsible for applying GBCI

standards, reviewing project LEED

documentation for conformance and determining

rating

Government Validation is default for all projects

(even when LEED certification is required)

GBCI letter templates must be used

BUILDING STRONG®

LEED Silver Certifiable

When “Certifiable” project is the requirement:

►Apply GBCI standards of interpretation

►Match GBCI documentation requirements

►“Certifiable”- Must be able to achieve GBCI Silver certification if submitted”

BUILDING STRONG®

Government Validation Review

District Review Team consists of a

minimum: a LEED AP, an architect and

electrical, mechanical, and civil engineer.

ACSIM Validation Program (USACE

HQ/ACSIM)

BUILDING STRONG®

Projects Required to Meet

LEED Silver All New Vertical Construction Projects with

Climate Controlled Facilities.

Renovation/Repair Projects that exceed

the Garrison Commander‟s Authority and

exceed 25% replacement cost.

Minimum 5% required to be GBCI LEED

Silver Certified.

BUILDING STRONG®

Projects Exempt from Meeting

LEED Silver Horizontal Construction

Vertical Projects that are not climate

controlled for human comfort.

Overseas Contingency Construction and

CONUS Interim Facilities

THIS DOES NOT MEAN THAT LEED

GOES AWAY!!!

LEED IN PROPOSALS

BUILDING STRONG®

DB Technical Evaluation(MILCON TRANSFORMATION PROJECTS)

Confirm mandatory, prohibited credits

Check for inconsistencies between LEED points and other portions of proposal

► Daylight, views points versus room layout & fenestration

► 30% energy reduction versus building envelope/insulation

► Bike rack/shower credit versus shower on plans

► Site heat island credit versus shaded, porous & concrete pavement

► Water use reduction credit versus proposed fixtures

Confirm correct assumptions on credits that require post-occupancy activities

BUILDING STRONG®

Innovation Credits

Innovation & Design credits are prohibited if they are not accompanied by a formal GBCI approval

► Match a credit from the USGBC ID Credits Catalog (at usgbc.org)

► Accompanied by a GBCI Credit Interpretation Ruling (CIR)

► Do not count toward minimum number of points in proposal unless complies (may seek approval after award)

USACE Adoption of LEED 2009

USGBC cut off v2.2 registrations on 26 June 09

ECB 2008-27 requested all Corps Districts register all

FY10 and FY11 known Army projects prior to cutoff date

All projects registered before cutoff date may be

executed using v2.2

► In MT RFPS indicate registered by Government,

administration transferred to Contractor after award

All FY10 and FY11 projects not registered under v2.2 will

have to be executed using LEED 2009

FY12 and beyond projects will use LEED 2009 NC

BUILDING STRONG®

LEED Certification Levels

LEED 2009

110 possible points

Platinum 80 + points

Gold 60 - 79 points

Silver 50 - 59 points

Certified 40 - 49 points

Launched Spring 09, all

projects not registered prior to

June 09 must use LEED 2009.

LEED v2.2

69 possible points

Platinum 52 - 69 points

Gold 39 - 51 points

Silver 33 - 38 points

Certified 26 - 32 points

USACE has used v2.2 since

FY08 when LEED became a

project requirement

LEED 2009

Program Requirements

To be considered for GBCI certification a building must:

Must comply with Environmental Laws

Be a complete, permanent building or space (no mobile structures)

Be either a new building or major renovation of a building in it‟s entirety (no partial buildings). Horizontally attached buildings (additions) are OK if physically distinct.

Have a project boundary that includes all contiguous land supporting that building‟s normal operations and construction.

BUILDING STRONG®

LEED 2009

Program Requirements

To be considered for GBCI certification a building must:

Must comply with minimum FTE & Floor Area requirements

Commitment to share whole building energy use data with USGBC.

Must Comply with a Minimum Building Area to Site Area Ratio.

BUILDING STRONG®

LEED 2009 Trends

BUILDING STRONG®

LEED 2009 – Changes in CreditsUpdated credits to incorporate CIR responses

WEc3 – Updated baseline water fixture usage

– Lavatory Faucets = 0.5 gpm (vs. 2.5 gpm)

– Kitchen faucets = 2.2 gpm (vs. 2.5 gpm)

IEQc4.3 revised to address all flooring types, not just carpet

IEQc3.2 – Clarified all finishes and final cleaning required to be

completed prior to building flush out.

Formaldehyde concentration reduced.

IEQc5 – Entryway systems required to be 10 feet rather than 6 feet.

IEQc8.1 – Daylight simulation, new prescriptive path, or measurement

BUILDING STRONG®

LEED 2009 Energy Efficiency

More focus needs to be placed on energy!

It often secondary to other credits that are cheaper to „buy‟

LEED effort may be discredited because buildings not performing as anticipated.

All projects pursuing certification will be required to provide utility usage data.

BUILDING STRONG®

LEED 2009

Raising the bar

►New Prerequisites added to energy efficiency

and water efficiency categories

– WEp1 20% water use reduction

– EAp2 10% energy savings over ASHRAE 90.1, 2007

►Threshold Change

– WEc3.1/3.2 increase to 30/40% from 20/30%

– EAc1 incremental percentage increase = more pts.

– EAc2 1% renewable energy = 1 pt.

BUILDING STRONG®

LEED 2009 New Credits

►Regionalization

– Achieve LEED credits appropriate to the local issues.

►Innovation in Design

– Additional points added to innovation category
