Energy Auditing Methodology and Performance Baselines
Syllabus Focus
- ASHRAE energy audit levels (I, II, III)
- Data collection and analysis
- Benchmarking and baseline development
- Energy performance indicators (EnPIs)
Key Notes
- ASHRAE defines three audit levels: Level I (walk-through), Level II (energy survey and analysis), Level III (detailed analysis of capital-intensive modifications).
- Baseline development requires at least 12 months of utility data normalized for weather, production, or other variables.
- Energy performance indicators (EnPIs) include energy use intensity (EUI), specific energy consumption (SEC), and normalized performance metrics.
- Benchmarking tools like ENERGY STAR Portfolio Manager compare facility performance to similar buildings.
- Measurement and verification (M&V) plans are essential for verifying savings from energy conservation measures (ECMs).
Must Know
- Understand the differences between ASHRAE audit levels and when each is appropriate.
- Know how to calculate and interpret EUI (kWh/m²/year or MJ/m²/year).
- Be able to identify key data sources: utility bills, sub-metering, equipment schedules, and weather data.
- Recognize common baseline adjustment methods: weather normalization, production normalization, and regression analysis.
Field and Exam Application
- Conduct a Level II audit for a commercial office building: collect 24 months of utility data, perform a walk-through, identify low-cost ECMs.
- Develop a baseline for a manufacturing plant using production data (e.g., kWh per unit produced).
- Use regression analysis to isolate weather-related energy consumption from base load.
High-Yield Distinctions
- Level I audit: simple walk-through, no detailed analysis; Level II: includes energy balance and cost analysis; Level III: includes simulation and financial analysis.
- Baseline vs. benchmark: baseline is facility-specific historical performance; benchmark is comparison to peers.
- Weather normalization: degree-day method vs. regression; regression is more accurate for variable loads.
Common Pitfalls
- Using less than 12 months of data for baseline; seasonal variations may be missed.
- Confusing baseline with benchmark; they serve different purposes.
- Ignoring non-routine adjustments (e.g., changes in occupancy or equipment).
- Overlooking data quality issues: estimated bills, missing intervals, or meter errors.
Review Tasks
- Practice calculating EUI from sample utility data.
- Review ASHRAE Standard 211 (Commercial Building Energy Audits) for audit procedures.
- Create a sample M&V plan for a lighting retrofit using Option A (retrofit isolation with stipulated parameters).
HVAC and Thermal System Optimization
Syllabus Focus
- HVAC system components and efficiency
- Thermal load calculations
- Boiler and chiller optimization
- Economizer and heat recovery
- Controls and commissioning
Key Notes
- HVAC systems account for 40-60% of building energy use; optimization focuses on reducing load, improving equipment efficiency, and enhancing controls.
- Thermal load calculations follow ASHRAE methods (e.g., heat balance, radiant time series) and are critical for right-sizing equipment.
- Boiler efficiency can be improved by reducing excess air, installing economizers, and using condensing boilers (90%+ efficiency).
- Chiller optimization includes variable speed drives, condenser water temperature reset, and free cooling with plate heat exchangers.
- Economizers use outside air for cooling when conditions permit, reducing compressor run time.
Must Know
- Understand the difference between sensible and latent heat and their impact on HVAC design.
- Know the components of a typical air handling unit (AHU) and their functions.
- Be familiar with coefficient of performance (COP) and energy efficiency ratio (EER) for chillers and heat pumps.
- Recognize common HVAC control strategies: DDC, PID loops, scheduling, and demand-controlled ventilation (DCV).
Field and Exam Application
- Optimize a chiller plant: implement condenser water temperature reset based on wet-bulb temperature.
- Retrofit a constant-volume AHU with variable frequency drives (VFDs) to reduce fan energy.
- Commission a boiler system: verify combustion efficiency, check stack temperature, and adjust air-fuel ratio.
High-Yield Distinctions
- Condensing vs. non-condensing boilers: condensing boilers capture latent heat from flue gas, achieving >90% efficiency vs. 80% for non-condensing.
- Air-cooled vs. water-cooled chillers: water-cooled have higher efficiency (lower kW/ton) but require cooling towers and water treatment.
- VAV vs. CAV systems: VAV reduces fan energy by varying airflow; CAV maintains constant airflow regardless of load.
Common Pitfalls
- Oversizing HVAC equipment leads to short cycling, poor humidity control, and reduced efficiency.
- Neglecting economizer maintenance: dampers can stick, sensors drift, and controls fail, wasting energy.
- Ignoring duct leakage: unsealed ducts can lose 20-30% of conditioned air.
- Setting thermostat deadbands too narrow (e.g., 1°F) causes excessive cycling.
Review Tasks
- Perform a load calculation for a small office using ASHRAE methods.
- Calculate the payback period for replacing a 10-year-old chiller with a high-efficiency model.
- Review ASHRAE Standard 90.1 for HVAC efficiency requirements.
Industrial Motor Systems and Compressed Air
Syllabus Focus
- Motor efficiency and sizing
- Variable speed drives (VSDs)
- Compressed air system components
- Leak detection and management
- System optimization strategies
Key Notes
- Motors consume about 70% of industrial electricity; efficiency improvements include premium efficiency motors (IE3/IE4) and VSDs.
- VSDs match motor speed to load, reducing energy consumption significantly for variable torque applications (fans, pumps).
- Compressed air systems are often inefficient: typical efficiency is 10-30% due to leaks, pressure drops, and inappropriate use.
- Leak detection: ultrasonic detectors can identify leaks; a single 3mm leak at 7 bar can cost $1,000/year in energy.
- System optimization includes reducing pressure, eliminating inappropriate uses (e.g., open blowing), and heat recovery.
Must Know
- Understand the relationship between motor load, speed, and power (affinity laws for fans/pumps).
- Know the difference between constant torque and variable torque loads.
- Be able to calculate compressed air leak costs using flow rate and operating hours.
- Recognize the components of a compressed air system: compressor, dryer, filters, receiver, distribution piping.
Field and Exam Application
- Audit a compressed air system: measure pressure at multiple points, estimate leak flow, and calculate potential savings.
- Specify a VSD for a pump serving a variable flow system (e.g., cooling tower).
- Replace a standard efficiency motor with an IE3 motor and calculate energy savings.
High-Yield Distinctions
- Affinity laws: fan/pump power is proportional to the cube of speed; a 20% speed reduction yields 50% power reduction.
- Positive displacement vs. dynamic compressors: reciprocating and rotary screw are common for industrial applications; centrifugal for large flows.
- Leak vs. artificial demand: leaks cause pressure drop, leading to higher compressor discharge pressure and increased energy use.
Common Pitfalls
- Oversizing motors: motors operate inefficiently below 50% load; replace with properly sized units.
- Ignoring pressure drop in piping: high pressure drop forces compressors to run at higher pressure, wasting energy.
- Using compressed air for cooling or cleaning when fans or blowers would be more efficient.
- Neglecting regular leak surveys: leaks can grow over time and account for 20-30% of total air demand.
Review Tasks
- Calculate the energy savings from reducing compressed air system pressure by 1 bar.
- Review the U.S. Department of Energy's Motor Systems Tip Sheet for best practices.
- Perform a simple leak quantification using a timed pressure decay test.
Measurement and Verification (M&V) Frameworks
Syllabus Focus
- IPMVP framework and options
- M&V plan development
- Baseline adjustment methods
- Savings calculation and uncertainty
- M&V for different ECM types
Key Notes
- International Performance Measurement and Verification Protocol (IPMVP) provides four options: A (retrofit isolation with stipulated parameters), B (retrofit isolation with all measured), C (whole facility), D (calibrated simulation).
- M&V plans must define baseline period, reporting period, boundary conditions, and adjustment methods.
- Savings = (baseline energy - reporting period energy) ± adjustments for independent variables (weather, production, occupancy).
- Uncertainty in M&V arises from measurement error, sampling, and modeling; acceptable uncertainty is typically ±10-20%.
- Option C is common for whole-building savings but requires large savings relative to baseline variability.
Must Know
- Understand the four IPMVP options and when each is appropriate.
- Know how to calculate savings using Option C: regression analysis of baseline data to predict reporting period energy.
- Be able to identify independent variables and develop adjustment models.
- Recognize the importance of metering accuracy and calibration.
Field and Exam Application
- Develop an M&V plan for a lighting retrofit using Option A: stipulate hours of operation, measure wattage reduction.
- Use Option C to verify savings from a building-wide HVAC upgrade: collect 12 months of baseline data, develop regression model, compare to post-retrofit data.
- Apply Option D for a complex ECM: create a calibrated simulation model using energy modeling software.
High-Yield Distinctions
- Option A vs. B: Option A stipulates one parameter (e.g., hours), Option B measures all parameters; Option A has higher uncertainty but lower cost.
- Option C vs. D: Option C uses measured whole-facility data; Option D uses simulation; Option D is better for interactive effects.
- Baseline adjustment: routine adjustments (weather, production) vs. non-routine adjustments (changes in building use).
Common Pitfalls
- Not accounting for non-routine events (e.g., equipment failure, occupancy change) in savings calculations.
- Using too short a baseline period (less than 12 months) leading to high uncertainty.
- Confusing gross savings with net savings: net savings account for free-ridership and spillover effects.
- Ignoring measurement error: sensors must be calibrated and properly installed.
Review Tasks
- Write a sample M&V plan for a chiller replacement using Option B.
- Perform a regression analysis on sample utility data to develop a baseline model.
- Review IPMVP Volume I (Concepts and Options for Determining Energy and Water Savings).
Renewable Energy and Decarbonization Strategies
Syllabus Focus
- Solar photovoltaic (PV) systems

Key Notes
- Solar PV systems convert sunlight to electricity; key metrics include capacity factor (10-25%) and levelized cost of energy (LCOE).
- Wind energy: onshore wind capacity factor 25-40%, offshore 40-60%; site selection is critical.
- Decarbonization strategies include electrification (heat pumps, EVs), renewable energy procurement (PPAs), and energy efficiency.
- Carbon accounting follows the Greenhouse Gas Protocol: Scope 1 (direct), Scope 2 (purchased electricity), Scope 3 (supply chain).
- Energy storage (batteries) enables higher renewable penetration by shifting supply to match demand.
Must Know
- Understand the components of a grid-tied solar PV system: panels, inverter, mounting, and metering.
- Know the difference between net metering and feed-in tariffs.
- Be able to calculate simple payback for a solar PV system given installation cost and annual savings.

- Develop a decarbonization roadmap for a manufacturing facility: identify electrification opportunities, on-site renewables, and REC purchases.
- Conduct a carbon footprint assessment for a commercial building using the GHG Protocol.
High-Yield Distinctions
- Solar PV vs. solar thermal: PV generates electricity; thermal heats water or air.
- On-site vs. off-site renewables: on-site reduces transmission losses but may be limited by space; off-site (PPAs) can be larger scale.
- Carbon neutral vs. net zero: carbon neutral offsets all emissions; net zero reduces emissions to near zero and offsets residual.
Common Pitfalls
- Overestimating solar PV production: ignore shading, panel degradation, and inverter losses.
- Double-counting emission reductions: e.g., claiming both RECs and carbon offsets for the same renewable energy.
- Ignoring embodied carbon in renewable energy equipment (e.g., solar panel manufacturing).
- Assuming renewable energy is always cheaper without considering grid integration costs.
Review Tasks
- Calculate the LCOE for a 100 kW solar PV system with given capital cost, O&M, and capacity factor.
- Review the GHG Protocol Corporate Standard for Scope 1, 2, and 3 definitions.
- Compare the payback period of a solar PV system with and without government incentives.
Energy Management Systems and Financial Analysis
Syllabus Focus
- ISO 50001 energy management system (EnMS)
- Energy policy and planning
- Financial metrics: NPV, IRR, payback
- Life cycle cost analysis (LCCA)
- Energy performance contracting (EPC)
Key Notes
- ISO 50001 provides a framework for continuous improvement in energy performance: Plan-Do-Check-Act (PDCA) cycle.
- Energy policy sets top management commitment and defines scope, objectives, and targets.
- Financial analysis for energy projects: net present value (NPV), internal rate of return (IRR), simple payback, and life cycle cost.
- Life cycle cost analysis (LCCA) considers initial cost, maintenance, energy, and replacement costs over the project life.

- Perform a life cycle cost analysis for replacing a boiler: compare initial cost, fuel savings, and maintenance over 15 years.
- Evaluate an ESCO proposal: verify baseline, savings guarantee, and M&V plan.
High-Yield Distinctions
- NPV vs. IRR: NPV gives dollar value of project; IRR gives percentage return; both should be positive for acceptance.
- Simple payback vs. discounted payback: discounted payback accounts for time value of money.
- ISO 50001 vs. ISO 14001: ISO 50001 focuses on energy; ISO 14001 on environmental management; they can be integrated.
Common Pitfalls
- Using too short a project life in LCCA (e.g., 5 years for equipment that lasts 20 years).
- Ignoring escalation rates for energy costs in financial analysis.
- Overlooking operation and maintenance costs in payback calculations.
- Assuming savings are constant over time without degradation or changes in operation.
Review Tasks
