Virtual Operations & Maintenance Training
Introduction: An overview of the topics to be covered in the series.
An Audit of Audits: What are the types of audits that are typically performed in facilities (ASHRAE 1-3, investment grade, building or system-specific etc.). What type of audit is appropriate for what purpose, desired outcomes?
Planning Energy Audits: Provides a checklist for pre-audit activities and considerations.
Energy Audit Scope/Methodology: The EMP 7-phase methodology is introduced. (Participants are provided with PDF of 246-page EMA Guideline.)
Development of Audit Plan: Includes introduction of ASHRAE Standard 211 with emphasis on the Level 2 audit requirements relevant to incentive requirements.
Standardized Industry Practices/Minimum Reporting Requirements: Material is presented from ASHRAE 211, EMA Guideline references and other applicable guidance.
Discussion of ECMs and FIMs: Provides context in the desired outcomes and key differences in ECMs and FIMs.
Sample Audit Exercises: Relates to pre-event materials distributed to participants.
Preparation of Audit Report: Samples reports are explained; recommended best practices are provided.
Introduction: Elements of effective facility documentation and tracking energy use. Units of measurement kWH, therms, gallons, etc. Discussion of metrics, degree days, metering, submetering (including BTU and smart metering).
Gathering Data: Monthly bills, supplier contract info. Discuss Portfolio Manager and its uses
Organizing Data: By building, operating entity, department, etc. Discuss submetering, BAS trend logs,
dataloggers, other means of stratifying consumption data, interval data.
Energy Balance: Demonstrate the four-part process for calculating.
Energy Baseline: Develop a baseline against which estimated energy consumption can be measured going forward. Baseline metrics (boundaries, year, fuel source, units of output, etc.)
Discussion of Influences on Energy Consumption: weather, occupancy patters, seasonal activities, behavioral, etc.
Energy Use Intensity: Introduce formula, sample calculations, EUI uses
Principles of Energy Benchmarking: What is energy benchmarking? Tools and resources, developing a benchmarking plan. The Commercial Buildings Energy Consumption Survey (CBECS).
Introduction: Site assessment / investigation techniques – key data collection
techniques; visual observations, measurements, trend logs, etc. Introduction of relevant principles of Facility Condition Assessment.
BAS-related Strategies: No Cost / Low Cost strategies for energy savings – examination of common control strategies, sequences, adjustments, BAS tips
Mechanical Part 1: Energy opportunities – common opportunities associated with building envelopes, lighting systems, filters, and domestic hot water systems
Mechanical Part 2: Energy opportunities – common opportunities associated with boilers, steam systems, and heating water systems
Mechanical Part 3: Energy opportunities – common opportunities associated with refrigeration & cooling systems (chillers, DX and CHW / CW distribution)
Mechanical Part 4: Energy opportunities – common opportunities associated with various HVAC terminal distribution systems (AHUs, various terminal units, etc.)
Office Part 1: Energy opportunities printers, copiers, fax machines, scanners, and multifunction devices
Office 2: Energy opportunities behavioral techniques featuring providing occupants with awareness, feedback, and actionable insight on their own energy usage.
Procurement: Overview of energy procurement with emphasis on auditing skills.
- Describe types of commissioning [including Cx, RCx and MBCx]
- Describe benefits of commissioning
- Introduce MBCx
- Standard definition [LBNL] is: “Monitoring based commissioning (MBCx) combines ongoing building energy system monitoring with standard retro-commissioning (RCx) practices with the aim of providing substantial, persistent, energy savings.”
- Other uses, fault detection, predictive maintenance, etc.
- Applications, enterprise wide, campus, single location, etc.
- Basic MBCx principles: baseline, analysis, actions, etc.
- Case studies.
- Implementing MBCx
- Using MBCx to ensure a persistence of energy savings and prevent building drift.
- Introduction: This webinar establishes how to evaluate and calculate various measures that are revealed by the audit work. It provides a basis for the decision-making that goes into creating a retrofit plan for the facility. Participants receive advance materials and sample problems relating to the concepts covered.
- Evaluating energy opportunities (various measures): Calculating energy and cost savings, examination of payback and ROI. The examples used will be to the extent possible designed to incorporate actual conditions derived from the pre-event survey submitted by participants.
- Ranking and Prioritizing Various Energy Savings Measures: Participants will learn methods of creating criteria for rank and prioritization. Issues such as owner goals, regulatory compliance, leveraging incentives, system lifetime expectations, etc. will be discussed.
- Establishing the Project Evaluation Criteria: Building on the material in the previous section, candidates will learn how to consider the information collectively and make key recommendations regarding their facility.
- Preparing the Report of Findings/Recommendations: Putting it all together. Sample reports will be presented and explained. Participants will be challenged to make the hard decisions that result in their recommendations and provide a rationale for same.
- Strategies for Ensuring a Persistence of Savings: The concept of “drift” is discussed. Measures that can prevent drift covered including, Ongoing Cx programs, monitoring strategies (sub-metering, trends, MBCx, etc.), and preventative / predictive maintenance
