1. The 5 th Annual Conference on Total Building Commissioning 2009 Commissioning Changes in LEED 2009 Paul McCown, PE, CxA, LEED AP, CEM SSRCx, LLC

2. Morning Warm-up TRUE/FALSE? According to ASHRAE, energy modeling is meant to predict the energy use of a building? False

3. Morning Warm-up True/False? The typical model of operating buildings is sustainable. Investments (from energy companies, or otherwise) in this model will be sustained.

4. Morning Warm-up True/False? Commissioning filled a gap in the design and construction process by which an operable building is turned over to an owner.

5. Morning Warm-up True/False? A gap still exists between what a new building controls system is capable of doing versus what is utilized.

6. LEED 2009 When? What is new and different? What does it mean to you – Cx Agent?

7. USGBC’s Mission: Promote the design and construction of buildings that are environmentally responsible, profitable, and healthy places to live, work and learn. The organization’s activities… Integrate building industry sectors Lead market transformation Educate owners and practitioners

9. New and Different

11. Prerequisites and credits in the LEED 2009 addresses 7 topics: Sustainable Sites (SS) Water Efficiency (WE) Energy and Atmosphere (EA) Materials and Resources (MR) Indoor Environmental Quality (IEQ) Innovation in Design (ID) Regional Priority (RP)

12. New and Different LEED 2009 certifications are awarded according to the following scale: Certified 40–49 points Silver 50–59 points Gold 60–79 points Platinum 80 points and above Out of 100 total points (with 10 “bonus” points available)

13. New and Different Harmonized – “Bookshelf Approach” Changes to Credit Weightings Regionalization LEED Online Green Building Certification Institute (GBCI)

14. What does it mean to you? LEED-NC v2.2 Commissioning LEED 2009 NC - Commissioning LEED-EB v2.0 Retro-Commissioning LEED 2009 EB

15. LEED-NC: Commissioning Intent: Verify that the building energy systems are installed, calibrated and perform according to the owner’s project requirements (OPR), basis of design (BOD), and construction documents. HVAC&R systems and controls Lighting and daylighting controls Domestic hot water systems Renewable energy systems (wind, solar, etc.)

16. LEED-NC: Commissioning – Changes for 2009 2 points for EA Credit 3 – Enhanced Commissioning instead of 1 point Innovation point possible for Envelope Commissioning

17. LEED-NC: Commissioning – Changes for 2009 “The same CxA overseeing the enhanced commissioning tasks must also oversee the fundamental commissioning tasks.” Table 2, note 4, pg. 221. See also “Who Can Be the Commissioning Authority?” 01/03/06 LEED 2.2 Commissioning Subcommittee, posted under LEED Reference Documents, http://www.usgbc.org http://www.usgbc.org

18. LEED-EB: Retro-Cx (old version) Intent – Verify that fundamental building systems and assemblies are performing as intended to meet current needs and sustainability requirements. Building Operation Plan – means for execution

19. LEED-EB: Retro-Cx Requirements – Verify installation, calibration, and operation for functionality and efficiency of the following: Heating, cooling, and humidity control Lighting Safety Controls

20. LEED-EB: Retro-Cx Building Operation Plan components: Use – occupancy and schedule by space type Static system requirements Functional system requirements

21. LEED-EB: Retro-Cx Performance Testing Plan (Cx Plan) components: Part A - Inspection Part B – Functional Verification (data logging)

22. LEED-EB: Retro-Cx Building Envelope HVAC Water Lighting Controls

23. LEED 2009 for Existing Buildings: Operations & Maintenance LEED-EB for O&M (short life-span) LEED 2009 for EB: O&M EA Prerequisite 1: Energy Efficiency Best Management Practices – Planning, Documentation, and Opportunity Assessment EA Credit 2.1 – Existing Building Commissioning – Investigation and Analysis EA Credit 2.2 – Existing Building Commissioning - Implementation

24. LEED Green Building Operations and Maintenance 2009 EA Credit 2.3 – Existing Building Commissioning – Ongoing Commissioning

25. EA Prerequisite 1: Energy Efficiency Best Management Practices Document sequence of operations Develop a Building Operations Plan Occupancy Schedule Equipment Run-Time Schedule Design setpoints for HVAC equipment Design lighting levels throughout the building Validate that the BOP is met during performance period

26. EA Prerequisite 1: Energy Efficiency Best Management Practices Develop a systems narrative for mechanical and electrical systems Create a narrative of the preventative maintenance plan with scheduled maintenance Conduct an ASHRAE Level I walk-through assessment 2007 ASHRAE Handbook – HVAC Applications ASHRAE Procedures of Commercial Building Energy Audits

27. EA Credit 2.1 – Existing Building Cx – Investigation and Analysis Option 1. Commissioning Process Develop RCx Plan Implement RCx Plan Document breakdown of energy use List operating problems and potential solutions Identify capital improvements with cost-benefit analysis

28. EA Credit 2.1 – Existing Building Cx – Investigation and Analysis Option 2. ASHRAE Level II Energy Audit Conduct an energy audit Implement RCx Plan Document breakdown of energy use Perform savings and cost analysis of “all practical measures” Identify “capital improvements” with cost- benefit analysis

29. EA Credit 2.2 – Existing Building Commissioning - Implementation Implement “no- or low-cost” operational improvements. Create a capital plan for major upgrades Provide training Demonstrate financial costs and benefits of implemented measures Update BOP to reflect changes

30. EA Credit 2.3 – Existing Building Commissioning – Ongoing Cx Implement an ongoing Cx program that addresses: Planning, testing, corrective action, on-going measurement Document ongoing commissioning cycle (24 months or less) Complete ½ of the scope prior to submission Update BOP or systems narrative as necessary

31. LEED 2009 for EB: O&M - Implementation “Performance Period”: 3 consecutive months minimum – most credits 1 year minimum – EA Prereq 2 and Credit 1 Not more than 24 months – any credit Terminate within 1 week – all credits Pay attention to detail Tie-in with other LEED Credits All WE Prerequisites and Credits All EA Prerequisites and Credits IEQ Prereq 1, Credits 1.x, 2.x
