3 Learning Objectives 1. Understand the different energy conservation approaches 2. Learn the advantage and disadvantages of each methodology 3. Learn when to apply each approach to gain the best value in your energy management program

4 Agenda The energy conservation challenge Three approaches Creating an energy management program Case studies benefits and uses

5 Limited Resources Worldwide Reserves Annual Demand Years Remaining Petroleum (billion barrels) 1, Natural gas (trillion cubic feet) 6, Coal (million short tons) 979,791 8, Water (billion cubic meters) 53,789 3,909 N/A EIA, CIA, World Bank, IEA 15% due to energy production

6 Limited Resources Buildings consume 46% of energy in the U.S. Energy consumption is the largest controllable cost in a building Easily addressed U.S. Energy Consumption by Sector as of January 2016 Buildings 46% Industrial 29% Transportation 25%

7 The Perception: Facilities is a Cost Center

8 Facilities is an Investment in Organizational Success The FM s challenge: Reduce Cost Add Value

9 Meeting Performance Requirements: Standards ASHRAE 90.1 Energy codes IECC Local/regional Benchmarking ENERGY STAR Mandatory

10 States with Mandatory Benchmarking Cities as of July 2015 Austin, TX Boston, MA Minneapolis, MN New York, NY Philadelphia, PA San Francisco, CA Seattle, WA Washington, DC Kansas City, MO Atlanta, GA Portland, OR

11 The Changing Landscape: Mandatory Programs Score = 75 Energy Star Label Potential Rating system models based on US DOE s Commercial Building Energy Consumption Survey (CBECS)

13 Agenda The energy conservation challenge Three approaches Creating an energy management program Case studies benefits and uses

14 Commissioning A process of ensuring that the building systems are operating in accordance with the design intent and the owner s requirements Defines the building systems performance criteria Provides a validated baseline for building performance Provides a means of tracking and evaluating building performance over time

15 The Commissioning Process Create a plan defining the objectives and requirements Select a commissioning team Identify the systems to be commissioned Execute the plan and document the results

16 Energy Audit A process by which an auditor conducts a walk-through of a building and identifies opportunities for energy and cost savings Provides recommendations for optimizing building systems Allows for a better understanding of how your facility operates Can tailor results to budgets, energy-saving goals, or how much you plan to accomplish

17 Energy Audit Levels I Walk-through analysis II Energy survey and engineering analysis III Detailed analysis of capital-intensive modifications

18 Building Re-Tuning A systematic process to identify and correct building operational problems that lead to energy waste Improves energy efficiency and tenant comfort Diagnoses malfunctioning or broken equipment and maintenance issues May be taken over by a facility manager or other in-house personnel

19 Building Re-Tuning Methods Observation-Driven Walkthrough of building and equipment following a checklist of visual and simple measurement checks Within BAS Interface Check for and correct a limited set of operational control issues within the building automation system (BAS) Data-Driven Deeper investigation of complex control issues from the BAS and energy meters

20 Agenda The energy conservation challenge Three approaches Creating an energy management program Case studies benefits and uses

21 Six Mistakes People Make 1. Believing nothing can be done 2. Not understanding what is important to the organization and how decisions are made 3. Lack of a plan 4. Not using the information and/or tools already available 5. Installing complex systems and/or technologies without the skills to operate and maintain performance 6. Lack of communication with building occupants

22 Elements of an Energy Management Program 1. Know your drivers 2. Set the goal 3. Baseline and benchmark 4. Assess facilities 5. Identify changes (capital renewal, O&M) 6. Implement measures 7. Monitor performance 8. Continuously improve

23 Advantages of the Three Approaches Building Re-Tuning Quick to implement Benchmarking Easy fixes Low cost Data collection/analysis Option of third-party of inhouse performance Operations-focused Long-term vision Energy Audit Flexible scope Identifies opportunities for savings Cost savings Energy conservation Apply to existing buildings Greater understanding of building Commissioning Tests functionality Confirms design intent Deliverable of report Availability of LEED points Third-party conducted

24 Comparison of the Three Approaches Commissioning* Energy Audit Building Re-Tuning Description Process Event Program Cost $$$ $$ $ Implementation time Level of Detail High Low - High Low Effort Required High Moderate Moderate Duration of Service 2-6 months 3-6 weeks 1 day Frequency of Service Continuous/3-5 years 3-5 years Continuous Service Provider Third party Third party Third party or in-house Energy Savings Types Outcome/Intent No/low cost, capital intensive Verification/validation of system operation, identification of programmable and operational changes No/low cost, capital intensive (depending on audit level) Energy and water conservation measures, recommendation (project list) No/low cost, operational changes Improved operations (decrease cost and energy and water usage, increase occupancy comfort) Deliverable Plan, report Report Program, execution plan Appropriate for Large/complex systems Any building/system Facilities with in-house FM Reference ASHRAE ASHRAE Procedures for Pacific Northwest National Commercial Building Energy Laboratory Audits *references commissioning for existing buildings (retro-commissioning)

35 Which Method Is Right for You? Ask yourself How complex is your building system? Do you have an in-house staff? Are you looking to receive a plan or report deliverable? Do you desire short- or long-term changes? How sure are you of an investment commitment? How much time and money are you willing to invest? Are you trying to reach a program goal (LEED, ENERGY STAR, etc)?
