1 Session no. B LEAD WITH LEED Paul Kai Architect, R.A., LEED AP Jon Yoshinaga Civil/Environmental Engineer, P.E., LEED AP U.S. Army Corps of Engineers 20 May 2010 US Army Corps of Engineers

2 Agenda Background LEED Silver Certified vs. Certifiable LEED in DB Proposals LEED in Design LEED in Construction LEED in the Future (LEED-NCv2.2 vs. LEED 2009) Resources

3 BACKGROUND

4 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) Guidance (2008)

5 USACE Guidance Army LEED Silver - Engineering Construction Bulletin (ECB ) LEED AP on staff (ECB ) Army waterless urinals beginning FY10 (ECB R) LEED Implementation Guide (ECB ) Army 50% construction waste diversion (ECB ) MSC Regional Sustainability Program Manager (ECB ) Briefing of Project SDD Features (ECB )

6 ARMY Policy Letter SDD Mandates LEED Silver beginning FY08 (05 January 2006) 50% construction waste diversion (05 July 2006) Energy reduction, water conservation, renewable energy to extent life cycle cost effective (27 April 2007)

7 LEED SILVER CERTIFIED VS. CERTIFIABLE

8 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

9 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

10 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)

11 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.

12 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!!!

13 LEED IN PROPOSALS

14 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 postoccupancy activities

15 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)

16 LEED IN DESIGN

17 LEED Design Coordination Meetings DB Post Award conference/dbb Pre- Design Conference Design Review conferences/obrs PM will coordinate formal endorsement, reporting and filing of final design score. May or may not include meeting.

18 Validating Design Credits Incorporate LEED credit into drawings/specs Design credits, checklists, templates and supporting documentation is a separable portion of the Design Analysis and provided with each required submittal Design documentation shall be in conformance with GBCI requirements for claimed credits.

19 LEED in Design (DB) FAST TRACKED SUBMITTALS - LEED Documentation: Submit LEED credit documentation for portions of work that will be fast tracked (e.g. all site credit design documentation with final site design).

20 LEED IN CONSTRUCTION

21 LEED Construction Coordination Meetings Three Coordination Meetings Review LEED Implementation Plan (DBB /DB ) Pre-Closeout Meeting review Documentation Notebook (DBB /DB ) Closeout Meeting review Final Documentation Notebook (DBB /DB )

22 LEED Documentation LEED Implementation Plan LEED Documentation Notebook LEED Calculations/Templates

23 LEED Implementation Plan Identify LEED AP(s) responsible for ensuring LEED Credits/PR and assemblying documentation Commissioning Agent Contract (EA PR1) Templates and Listing of Req. Support Docs List of Plans and proposed schedule. Procurement Plan by Credit/PR

24 LEED Documentation Notebook Available on site at all times Formatted to Match LEED Designations Include all calculations, plans, material procurement documentation Update monthly (min)!!!(dbb /DB ) Can be deducted from monthly progress payment(s).

26 REMEMBER Please read your contract. We want you to succeed.

27 LEED IN THE FUTURE

28 USACE Adoption of LEED 2009 USGBC cut off v2.2 registrations on 26 June 09 ECB 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

29 LEED Certification Levels LEED v possible points LEED possible points Platinum points Platinum 80 + points Gold points Gold points Silver points Silver points Certified points Certified points USACE has used v2.2 since FY08 when LEED became a project requirement Launched Spring 09, all projects not registered prior to June 09 must use LEED 2009.

30 LEED Code References LEED v2.2 ASHRAE 90.1, 2004 ASHRAE 62.1, 2004 SMACNA IAQ, 1995 LEED 2009 ASHRAE 90.1, 2007 ASHRAE 62.1, 2007 SMACNA IAQ, 2007 Credits remain largely unchanged except for updated code references

31 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.

32 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.

33 LEED 2009 Language that addresses mixed use projects More options for Low-Emitting & Fuel-Efficient Vehicles Expanded options for Heat Island Effect Non Roof materials Inclusion of requirements for non-carpet flooring Inclusion of permanent monitoring system for thermal comfort verification Alignment and clarification of Daylight and Views requirements

34 LEED 2009 Checklist

36 Point Comparison

37 LEED 2009 Trends

38 LEED 2009 Changes in Credits Updated 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

39 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.

40 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.

41 New Credits Regionalization LEED 2009 Achieve LEED credits appropriate to the local issues. Innovation in Design Additional points added to innovation category
