Phoenix Convention Center Phoenix, Arizona Building Performance:Building Operator Training to Save Energy Brian Gilligan, PE, LEED AP, General Services Administration Amanda Hatherly, Santa Fe Community College’s New Mexico Energy Smart Academy Srinivas Katipamula, Ph.D., Staff Scientist, PNNL Facilitator: Lisa Shulock, LEED AP O+M, Consortium for Building Energy Innovation/Penn State August 11, 2015

2. Energy Exchange : Federal Sustainability for the Next Decade Focusing on two hands-on training programs for building operators with documented energy and cost savings: – Building Operator Certification (BOC) – Building Re-Tuning Training Federal Buildings Personnel Training Act and its relevance to you 2 Session Overview

3. Energy Exchange : Federal Sustainability for the Next Decade 1.Decide whether you, a co-worker or subordinate is a good candidate to attend BOC and/or BRT 2.List 3-5 common energy-saving opportunities that are discovered during building re-tuning 3.Make a persuasive case to your management or decision-makers about the value of investing in building operator training 3 Review Session Objectives

4. Energy Exchange : Federal Sustainability for the Next Decade Other than this conference, when was the last time you participated in training? How many of you think the building(s) you work in are energy efficient? Very? Somewhat? Not so much? Do you think the savings from training facilities staff generally result in energy savings of? – 0-5% – 5-25% or – 25-50% – 50% or greater 4 Questions

5. Energy Exchange : Federal Sustainability for the Next Decade Nationally recognized certification Project-based Short quiz assessments Apply class learning to the building you are in Main focus is energy efficiency 72 hours, typically over 7 months 5 BOC – The Basics

6. Energy Exchange : Federal Sustainability for the Next Decade Building Re-Tuning is identifying and implementing no- and low-cost improvements to increase building energy efficiency. The training is targeted at people working in buildings who can learn to re-tune their buildings Training formats: – Online on-demand (2-6 hours) – In-person (1-2 days) Training options: – Small building without BAS – Large building with BAS 6 BRT – The Basics

7. Energy Exchange : Federal Sustainability for the Next Decade FBPTA - Requirements of the Act Core Competencies for Federal buildings Personnel Recommended Curriculum and Continuing Education Annual updates to Competencies and Curriculum Compliance by all Federal buildings personnel Method for contractor compliance 7 “…core competencies …relating to building operations and maintenance, energy management, sustainability, water efficiency, safety (including electrical safety) and building performance measures.”

12. Energy Exchange : Federal Sustainability for the Next Decade BOC Level 2 BOC 201 – Preventive Maintenance & Troubleshooting Principles BOC 202 – Advanced Electrical Diagnostics BOC 203 – HVAC Troubleshooting & Maintenance BOC 204 – HVAC Controls & Optimization SUPPLEMENTAL COURSES (2 offered per course series) BOC 211 – Motors in Facilities BOC 212 – Water Efficiency for Building Operators BOC 213 – Mastering Electric Control Circuits BOC 214 – Introduction to Building Commissioning BOC 215 – Electric Motor Management BOC 216 – Enhanced Automation and Demand Reduction 12

13. Energy Exchange : Federal Sustainability for the Next Decade Documented Savings Results Across All Evaluation Reports kWhkWTherms Average Annual Savings Per Certified Operator 92,00012.51,260 Range 9,940 - 181,000 Range 3 - 37 Range 36 – 3,104 Average Savings Per Square Foot/Year 0.26- *- Range 0.02-.50 -- Average % Energy Savings Per Certified Operator 2.4%-- Notes: *For the few studies that calculated kW per sq. ft. the results varied widely so no conclusions were drawn. 13

14. Meta-Analysis of ~100 Buildings What are the common re-tuning measures? What are the expected savings, if a building is re-tuned? Analyzed over 100 buildings, documented the common re-tuning measures –Documented whole building energy savings for a subset of the buildings (~25) ~25 buildings ~50 buildings ~30 buildings 14

15. Classification of Re-tuning Measures 15 Level of Effort Potential Savings For example, most desirable measures to implement are those that yield high savings but require low effort Scheduling measures fall in this category

16. Meta-Analysis: Common Measures –Lack of proper schedules for HVAC and lighting systems –Lack of schedules for exhaust fans or fans running during warm-up mode –Lack of night set backs –Lack of occupancy-based controls for common areas (conference rooms, kitchen, etc.) –Lack of photo sensors or sensors in the wrong locations for exterior lighting controls –Lack of automatic lighting controls –One or more faulty sensors 16 Improper air flow sensors or stuck zone dampers Improper minimum outdoor-air setting during morning warm-up Lack of static pressure or discharge temperature reset on AHUs Lack of chilled/hot water temperature reset Lack of differential pressure reset on chilled/hot water distribution loop Improper heating/cooling set points or dead bands Almost every building had some re-tuning measures to consider

17. Meta-Analysis: Distribution of Re-tuning Measures Although the sample is biased towards office buildings, there appears to be no difference in the distribution of re- tuning measures by building type, vintage, and size 17

18. Meta-Analysis: Summary 18

19. Meta-Analysis: Summary (cont.) Annual energy savings ranged between 2% to 26%, with a median savings of 15% Annual normalized cost savings ranged between 0.0$/sf to 0.6$/sf, with a median savings of 0.12$/sf If all re-tuning measures identified were implemented, the savings could have been even larger 19
