Task 9: We determine our significant energy uses (SEUs), identify and monitor their relevant variables and energy performance, and identify the persons that affect the SEUs. We have a process to review and update SEU data and related information, including our methods and criteria to determine that an energy use should be an SEU.

Detailed Guidance: Significant Energy Uses (SEUs)

  1. Identify the energy uses that consume the most energy within your boundaries.
  2. Identify factors and persons that affect the energy consumption of identified energy uses.
  3. Establish a selection criteria for identifying which of these energy uses should be a significant energy use (SEU).
  4. Determine SEU energy performance based upon energy consumption and relevant variables is appropriate.
  5. Review the SEU selection criteria as part of the SEU update process.

Significant energy uses (SEUs) are energy uses identified by the organization as having major energy consumption and/or considerable opportunity for improvement. They are a key component of the 50001 Ready system and require additional attention and action relative to other energy uses. It’s important to identify your organization’s SEUs using defined criteria for significance. When starting out with a 50001 Ready system, it is recommended to tackle just one or two SEUs.

Once identified, the current energy performance of SEUs needs to be determined. The performance of the SEU is dependent on factors that influence its operation. Identifying these factors or relevant variables will help you to determine their current energy performance. Once the performance is determined, processes should be implemented to continually monitor that performance. Collecting, analyzing, and tracking data on SEU performance can reveal opportunities for improvement.

In addition to determining and then monitoring SEU energy performance, it is important to identify the people that influence or affect the operation of SEUs. In most cases, the energy performance of SEUs is affected by persons who perform ongoing operational control and maintenance activities. However, there may be other personnel who also influence or affect the SEUs; for example, site managers or engineers. Once these people are identified it will be important to engage with them so they are aware of the focus on the SEU and any upcoming capital or operational improvements to be made.

Lastly, it is important to plan for how and when the energy team will review and update the criteria and process of selecting SEUs and consider if current and potential SEUs meet selection criteria. Over time, the energy uses identified as significant may change as your organization continues to improve its energy performance. Also over time, it may be appropriate to modify the evaluation and selection methodology based on changes in sites, equipment, systems, or processes.

This guidance is relevant to sections 6.3 b) and c) of the ISO 50001:2018 standard.

By definition in ISO 50001, significant energy uses (SEUs) are energy uses with substantial energy consumption and/or considerable potential for energy performance improvement. Criteria for the selection of SEUs should include both of these determining concepts. Your organization decides as part of this criteria what is considered to be “substantial” consumption and what is considered to be “considerable potential” for energy performance improvement.

Most organizations will determine SEUs based on the largest energy consuming systems and equipment identified in an energy balance. However, SEUs also may be determined based on considerable potential for energy performance improvement (see Task 10 Improvement Opportunities). This can be a good option if your organization has been engaged in energy management activities for many years and the opportunities for additional improvements to the largest energy-consuming systems are limited, or if organizational hurdles exist to meaningfully change the largest energy-consuming systems. In this situation, you can focus on smaller systems that have greater opportunity for energy performance improvement.

In Task 8 Energy Data Collection and Analysis, the energy balance was presented as a method of reasonable assurance that you have accounted for all the energy consumed in your organization. Once a balance is achieved, one of the most common methods for determining SEUs is to rank the energy uses by consumption. You can then establish a certain threshold of energy consumption or a certain percentage of total consumption as the selection criterion for significance (see Task 8 Energy Data Collection and Analysis). The top energy consuming uses can then be evaluated for improvement opportunities, if they haven’t been already (see Task 10 Improvement Opportunities). However, this is only an example of one way to approach the selection criteria; you can choose different approaches that are appropriate for your organization.

In industry and many businesses, the 80/20 rule typically applies (see Task 8 Energy Data Collection and Analysis); i.e., 80 percent of the energy consumption will be accounted for by 20 percent of the equipment or processes. Typically, only a few energy systems consume the majority of a site’s energy. Consider focusing on these, and apply the criteria for significance. Energy management is a continual improvement process, and over time additional energy uses can be identified as significant.

For newly implemented energy management systems, it is important to start simply. Consider limiting the number of SEUs in your new EnMS, since these energy uses can require the most resources. ISO 50001 requires that you address operational and maintenance controls (see Task 17 Operational Controls), procurement (see Task 19 Energy Considerations in Procurement), and monitoring and measurement (see Task 21 Monitoring and Measurement of Energy Performance Improvement) of all the SEUs identified. You will also need to consider SEUs when establishing objectives and energy targets (see Task 12 Objectives and Targets) and Task 10 Improvement Opportunities). These requirements can quickly consume available resources.

Once SEUs are identified, collect appropriate energy data to determine their performance (part of Task 8 Energy Data Collection and Analysis). Factors that can affect SEU energy performance are called relevant variables (for details on relevant variables see Task 8Energy Data Collection and Analysis).

For commercial or institutional facilities, occupancy and weather can often be variables affecting consumption. For industrial facilities, production is generally an additional variable that affects energy consumption of SEUs. Using engineering logic, think about the potential SEU and what may be relevant variables. In addition to weather, occupancy, and production, consider the following: operating schedule, product mix, input materials, and season.

Verify the impact of specific variables on SEUs by collecting relevant energy data and comparing it to appropriate variable data to determine the relationship, if any, of the change in energy consumption coinciding with the change in the variable. One way to define the relationship is to graph the energy data over a defined time period and compare it to a graph of the variable data, such as average daily temperature, over the same period and determine if there are coincidental variations. Consistent variations between the two could indicate a valid relevant variable. Anomalies between the two may indicate other relevant variables are also a factor in energy consumption of the SEU. Statistical techniques or more sophisticated engineering calculations may be required for analysis of multiple variables.

Energy performance indicators (EnPIs) (see Task 11 Energy Performance Indicators and Energy Baselines) can be developed to define the energy performance for a SEU. For many common energy systems that are often identified as SEUs there are standardized EnPIs used by energy professionals. Similar EnPIs can be developed for sites, equipment, processes, personnel, or other systems. Consider normalizing the EnPIs for the SEUs using relevant variable data; this may lead to more meaningful results. Normalized EnPIs and related baselines allow performance comparisons under equivalent conditions.

Track EnPI values to reveal trends that allow comparison of the performance of SEUs over time. Benchmarking, which is the practice of comparing an SEU to the best in class or theoretically optimal performance of similar uses, may be used when available (see Task 8 Energy Data Collection and Analysis).

Energy performance of an SEU also can be determined and monitored by operational or maintenance parameters (see Task 21 Monitoring and Measurement of Energy Performance Improvement).

Operations of SEUs are among the “key characteristics” affecting energy performance that are regularly monitored, measured, and analyzed (see Task 21 Monitoring and Measurement of Energy Performance Improvement). Your organization decides on the method for determining the energy performance, identifies the monitoring and measurement necessary for data collection, and includes it in the Energy Data Collection Plan (see Task 8 Energy Data Collection and Analysis).

Data analysis is a continuous process. Continue to monitor SEUs and collect, analyze, and track the data. This can have the added potential benefit of identifying opportunities for energy performance improvement of the SEUs.

Identify the employees, onsite contractors, and service providers whose work activities affect SEUs. These personnel may need additional awareness training or specific qualifications to ensure that the operations associated with the SEU are followed correctly and, if applicable, that energy performance targets are achieved. This is particularly true for personnel responsible for the operation or maintenance of sites, equipment, systems, or processes identified as SEUs. The optional Playbook worksheet can be useful in helping to identify the potential types of personnel who may be relevant to an SEU.

The process of identifying SEUs is part of the energy review. Documented information must be maintained on the criteria and process used to select SEUs. Documented information should be updated as the selection criteria and process of identifying SEUs changes. The optional Playbook worksheet can help document the criteria and method used to determine significant energy uses.

Plan for how the energy team will regularly review and update which energy uses are selected as SEUs, as well as the selection criteria and process methodology. Management input should be solicited during this process. Changes in the selected SEUs or the evaluation and selection process may be necessary for a number of reasons:

  • Improvement projects have reduced consumption of an SEU below the selection threshold.
  • Resources available to address SEUs have changed.
  • Business changes have affected SEU focus/selection.
  • New processes have altered energy consumption patterns.
  • Major changes in sites, equipment, systems and energy-using processes have occurred.

Documenting SEU information is a recommended best practice. Record the significant energy uses, the areas or operations with which they are associated, and the affected personnel (by position title). A simple spreadsheet can serve as the list of current SEUs and a place to record other information that will be needed to ensure proper management of significant energy uses.

Review your SEUs for any changes to relevant variable, energy performance, or changes to personnel with control over the SEUs.

Consider whether any changes in your scope and boundaries warrant the addition or removal of SEUs.

The energy review is critical for many of the downstream processes of the EnMS. Understanding each energy source and use is vital. Having a few select SEUs keeps the workload manageable the first couple of years.

Remember, SEUs can be facilities, equipment, processes, or systems.  SEUs may change over time as improvements are implemented or operational processes change.

Not required for 50001 Ready recognition

Significant energy uses (SEUs) are energy uses identified by the organization as having substantial energy consumption and/or considerable potential for improvement. They are a key component of the 50001 Ready system and require additional attention and action relative to other energy uses. It’s important to identify your organization’s SEUs using defined criteria for significance. 

When including energy-related GHG emissions in your EnMS, your organization should include the potential for improving energy and energy-related GHG emissions performance as determining concepts for the selection of SEUs. Criteria for selecting SEUs will help your organization integrate GHG emissions into the management of SEUs could include:

  • Identifying factors and persons that affect the energy-related GHG emissions of SEUs
  • Determining SEU energy-related GHG emissions performance based upon energy consumption and relevant variables
  • Monitoring and measuring SEU energy performance improvement

If you do not have an existing 50001 Ready-based EnMS and want to build one that also helps your organization manage energy-related GHG emissions, you should follow the guidance in the “Full Description” tab keeping the following in mind:

  1. Determine and apply criteria for selecting SEUs.  Make sure to include criteria for determining SEUs energy-related GHG emissions and/or energy-related GHG emission reduction opportunities (or any other GHG-related approach that is appropriate to your organization).
  2. Determine relevant variables and performance of SEUs and implement a monitoring process.  When including GHG emissions as criteria for selecting SEUs, consider the relevant variables that can affect energy-related GHG performance and the data that will need to be collected to determine the energy-related GHG emissions performance of the SEU.  Refer to Task 8 Energy Data Collection and Analysis for an overview of data collection processes and determining relevant variables.  Make sure you build upon the energy data that is already being collected and your existing list of relevant variables.  If the potential for improving energy-related GHG emission performance is included as criteria, refer to Task 10 Improvement Opportunities for an overview of the processes for identifying GHG performance improvement opportunities. Include GHG-related measurements in the monitoring of SEUs.  Follow the process detailed in Task 21 Monitoring and Measurement of Energy Performance Improvement.
  3. Identify persons who affect the SEUs. Identify the person(s) who affect SEUs and ensure that they have the appropriate training or qualifications to manage both energy and energy-related GHG emissions.
  4. Plan for updating SEU selection. Include energy-related GHG emissions in your process for reviewing and updating SEUs.  Keep in mind that business changes can affect the relative importance of energy-related GHG emissions and therefore the criteria for selecting SEUs.
  5. Document your SEU information. Include documentation on the relative importance of energy-related GHG emissions (performance and reduction opportunities) in your SEU information.

If you have an existing 50001 Ready-based EnMS and want to adapt it to manage GHG emissions, you should:

  1. Review your criteria for selecting SEUs.  Review your criteria for defining SEUs to establish how to integrate energy-related GHG emissions and/or energy-related GHG emission reduction potential or to determine if there is another GHG-related approach that is appropriate to your organization.
  2. Review relevant variables and performance of SEUs and review your monitoring process.  When adding energy-related GHG emissions as criteria for selecting SEUs, consider the relevant variables that can affect energy-related GHG performance and the data that will need to be collected to determine the energy-related GHG emissions performance of the SEU.  Refer to Task 8 Energy Data Collection and Analysis for an overview of data collection processes and determining relevant variables.  Make sure you build upon the energy data that is already being collected and your existing list of relevant variables.  If the potential for improving energy-related GHG emission performance is added as criteria, refer to Task 10 Improvement Opportunities for an overview of the processes for identifying energy-related GHG performance improvement opportunities. Implement monitoring of SEUs, including GHG-related measurements.  Follow the process detailed in Task 21 Monitoring and Measurement of Energy Performance Improvement.
  3. Review the list of persons who affect SEUs. If SEUs have changed, identify the person(s) who affect SEUs and ensure that they have the appropriate training or qualifications to manage both energy and GHG emissions.
  4. Review your plan for updating SEU selection. Review your plan for updating SEU selections to see if the inclusion of GHG emissions changes the plan.
  5. Document your SEU information. If your criteria for selecting SEUs, the list of SEUs, or the affected personnel have changed, make sure to update the documented SEU information.

The guidance for this task is from the following sections from the ERP Framework: ERP Framework Introduction and Milestone 1.

The process of identifying SEUs can involve gathering information on the characteristics of individual buildings within the portfolio and grouping them into categories for prioritization. Buildings within each category can then be benchmarked using tools like ENERGY STAR Portfolio Manager to identify opportunities for energy performance improvement.

Gather information on the selected characteristics of individual buildings to better understand what differentiates the buildings within the portfolio. Generally, three to five characteristics will be sufficient to categorize a portfolio. The organization may already have information available on some of these characteristics, but others may need to be collected internally or with the support of a consultant. Automated methods can be used to collect some of the characteristics, such as through virtual data-driven audits or automated building-stock analysis, to help speed the process. (Milestone 2)

Once characteristic information has been collected, group buildings in the portfolio into different categories for prioritization. This multi-layer approach to categorization helps owners define a subset of buildings that represents the breadth of their portfolio and captures the different emissions reduction strategies that may be applied. Within each category, buildings can be benchmarked using the ENERGY STAR Portfolio Manager (or a similar tool). Other analysis approaches can also provide a high-level identification of emissions reductions opportunities early in the process. (Milestone 2)

After calculating its GHG inventory and setting portfolio emissions reduction targets, an organization defines characteristics that differentiate its buildings (e.g., HVAC system type and GHG emissions intensity). These characteristics are used to categorize buildings in the portfolio. For example, buildings with packaged rooftop units are in one category, and buildings served by a central HVAC plant are in another category. Next, the organization selects a sample of buildings for decarbonization audits that represent the different categories. The framework refers to these as representative buildings. The results from these representative building audits are scaled across similar buildings to estimate emissions reduction impacts and develop potential scenarios at the portfolio level. Additionally, the scenarios are influenced by portfolio-level assessments such as fleet electrification studies, solar opportunity analysis, and utility green power options. After evaluating the scenarios, the organization selects and defines their emissions reduction pathway.

Consider both direct (Scope 1) and indirect (Scope 2, such as electricity) emissions when identifying the organization’s significant GHG emitters.

The guidance for Task 9 is found within the following section of the ERP Industrial Framework:

Milestone 2:

Identify and quantify GHG emissions for Significant Greenhouse Gas Emitters (SGEs) – Identify the largest GHG emissions sources (also known as “significant GHG emitters” or SGEs) both at the facility level and at the equipment/process level. SGEs could be individual, discrete pieces of equipment, such as a boiler, or could be sources from processes or equipment that, while individually small, are distributed widely enough to be significant, such as refrigerant leaks from chillers or air conditioners. Once SGEs are identified by estimation first, accurately determine the energy consumption and GHG emissions for these systems. Identify key variables that determine performance of SGE systems and collect, analyze, and track performance data.

Benchmark SGEs – Benchmark SGEs relative to similar systems to gauge performance. This can be done internally (e.g., across facilities within the same portfolio) or externally, depending on data availability. In the absence of reliable data on comparable systems, SGEs can instead be benchmarked against their own past performance. Benchmarking can be used to identify best practices and ideal operating conditions as well as opportunities for performance improvement.

Beyond the quantitative measures of this task, users may refer to 42 U.S. Code § 8253 for guidance on identifying high priority projects and developing criteria for what such high priority projects might be.

This task should be used to identify facility-specific operations that should have energy performance improved most immediately. Plans already developed for how a facility will identify operations that use the most energy and prioritize energy improvement projects may be used to support the completion of this task.

While “Relevant Variables” is not a topic explicitly covered through federal requirements, use this task to identify and address those relevant variables that are affecting SEUs and thus energy performance. Any criteria detailing the most immediate and significant factors that may affect energy performance should be used to support completion of this task.

Implementing water efficiency starts with understanding a facility’s water-using processes and significant water uses (SWUs). SWUs are water uses identified by the organization as having substantial water consumption and/or considerable potential for improvement. They should be a key component of your water management strategy and require additional attention and action relative to other water uses. It’s important to identify your organization’s SWUs using defined criteria for significance.

To complete this task, start by conducting a facility water assessment to understand how much water your facility uses, and which processes require the most water. As part of the water assessment, note the operating schedule, flow rate, model number, and condition for each piece of equipment. You can also use a bucket and stopwatch and make a quick, rough estimate of equipment flow rate (e.g., faucets, showerheads, and once-though cooling). During the walk-through, pay particular attention to drain lines that are plumbed to floor drains in building mechanical spaces and utility chases. Make sure to collect information about building occupancy, equipment flow rates, the number of typical uses in a given time frame (daily or weekly), and the number of days or weeks operated annually. After walking through the buildings, use the data collected to estimate water use for each equipment type.

Next, analyze available water data to understand current water use trends. If trends exist, determine the cause. Evaluate any seasonal patterns and compare them to the inventory of uses. Are any uses seasonal, such as cooling tower use or irrigation? The seasonal pattern of water use (peak use) can help quantify these uses.

An assessment also helps with identifying potential water-saving opportunities and calculating the payback periods to help prioritize options to reach water-saving goals. Use the EPA’s Commercial & Institutional Facilities Fact Sheet for additional support. The following sections from the FEMP’s Water Manual provide further information that can help with this task.

  • 3.1.3 Determine Facility Water Use Baseline
  • 3.1.4 Conduct a Walk-Through Survey
  • 3.1.5 Estimate Water End-Use Consumption
  • 3.1.6 Develop a Water Balance

Install submeters on water-intensive processes, such as cooling towers and irrigation systems, to help manage these processes better and meet annual reporting requirements. Submeters can provide powerful data to help better manage water and to help program managers better understand water use and make informed decisions. Submetered data can improve water management through trend monitoring, process monitoring, leak detection, and water use reporting.

According to FEMP’s Water Metering Resources (Water Metering Prioritization), agencies are required to develop metering plans to inform how they will deploy meters through their building stock. Guidance on water metering is provided by FEMP in the Federal Building Metering Guidance, which helps agencies prioritize the application of water meters to their building inventories. Meters cost money to purchase and install, and agencies and installations with multiple buildings distributed over a region or campus usually balance water metering needs with available funds in the current year and anticipated out-year funding. To do this, agencies and sites evaluate their building inventories to (1) prioritize the order in which buildings should be metered for water, and (2) develop an implementation schedule that maximizes the potential benefits.

Because water metering can be a complicated and costly task, FEMP has a detailed process for building water meter prioritization. Follow the steps outlined by FEMP below to prioritize buildings for water meters using a more comprehensive water use approach. These steps focus on a single campus, but they also could be utilized at the agency level (note that irrigation metering is handled separately from building water meters and should be prioritized by the size of the irrigated area).

Step 1: Develop a list of buildings with building type and square footage from the campus real property database.

Step 2: Identify the number of occupants per building from associated building data or human resources records.

Step 3: Determine the buildings’ water consuming equipment such as plumbing, chiller plants, cooling towers, steam systems, commercial kitchens, vehicle wash, laundry facility, and lab equipment. This equipment can be identified through equipment inventory databases or through facility manager interviews. See FEMP’s Best Management Practices for Water Efficiency for an extensive list of water consuming equipment.

Step 4: Estimate the daily water use for each building based on the type of water using equipment identified.

Step 5: Sort the building list by daily water use to determine the priority for which buildings should be metered.

Tools and Resources:

Task Playbook numbers 8 and 9 are tied together. Task 9, the determination of the SEUs, is based on the data collection and analysis of energy conducted in Task 8.

Please remember that there are at least two items that must be considered in the selection of SEUs:

  1. The energy use accounts for substantial energy consumption, and/or
  2. The energy use offers considerable potential for energy performance improvement

A good example of this is lighting. While lighting may only be a small part of your total energy use, it may have an excellent potential for energy performance improvement based on adding lighting controls and changing to new LED lighting (assuming limited use of LEDs currently).

The selection of SEUs is very important to the implementation of your EnMS because there are significant requirements to address for every SEU selected in downstream task Playbooks. So to avoid overburdening your energy team, it is recommended initially to select no more than two or three SEUs.

Keep in mind that SEU-related requirements in later tasks include:

  1. SEUs must be considered in the selection of objectives and energy targets (Task 12)
  2. For each SEU selected: (Tasks 8 & 9)
    1. Determine relevant variables
    2. Determine current performance
    3. Identify persons working on SEUs
  3. For each SEU selected, you must collect data on: (Task 8)
    1. Relevant variables
    2. Energy consumption
    3. Operation controls criteria
  4. Develop operational and maintenance controls for all SEUs, included any outsourced processes (Task 17)
    1. Communicating these controls to relevant personnel
    2. Training about these controls to relevant personnel
    3. Implementing the methods for documenting these controls
  5. When procuring energy using products, equipment and services that have, or can have, an impact on SEUs, the organization shall inform suppliers that energy performance is one of the evaluation criteria for procurement (Task 19)
  6. The monitoring and measurement plan must include the operation of the SEUs (Task 20)

This task may be used to incorporate SEUs into a plan for identifying site-specific systems that should have an impact on site energy performance almost immediately. Plans already developed for how a site identifies systems that use the most energy and prioritize energy improvement projects may be used to support the completion of this task. Existing maintenance schedules for equipment and processes that are determined to be SEUs can also be used.

For many hotels, HVAC and lighting dominate energy consumption, so common SEUs will be chillers, boilers, air handlers, and lighting.  However, your site may have different or additional SEUs, such as kitchen equipment.

"The energy team can develop an inventory to identify the operations and pieces of equipment in the facility consuming the most energy. The inventory can include the equipment names, nameplate horsepower (if applicable), hours of operation per year, measured power consumption, and total kilowatt-hours of electrical consumption per year, and age (if applicable)… In some cases, this information may already have been stored in a maintenance management system or may have been collected by the auditors." (EPA WW Guide, p.11)

In addition to an equipment inventory, utility bills, which commonly can be found stored (either physically or digitally) at the facility, can also prove helpful in identifying significant energy uses. "Utility bills indicate how much energy a plant consumes across the facility, but submetering provides more detailed data on the energy consumption of specific treatment stages, and even on individual pieces of equipment, depending on how extensively meters are installed." (SWIFt EDMM, p. 8)

This example from the Sustainable Wastewater Infrastructure of the Future Accelerator (SWIFt 1.0) can act as a gut check for facilities but is not necessarily true for all: "…pumping and aeration usually account for about two-thirds to three-quarters of a wastewater facility’s energy consumption. Within that portion, aeration [typically] dominates, making up about three-quarters of the share." (SWIFt EDMM, p.8). Ultimately it is up to the facility to define the criteria for determining the SEUs, and applying that criteria to determine significance.

Helpful free tools provided by the Department of Energy and Environmental Protection Agency for tracking energy usage are listed below:

Both ISO 14001:2015 and ISO 50001:2018 use a construct of “significance.” In an ISO 14001 environmental management system (EMS) significant environmental aspects are determined using environmental impact criteria, while in an ISO 50001:2018 EnMS, significant energy uses are determined using criteria related to consumption and/or improvement opportunities. Although the criteria (and typically the methodologies) used to determine significance differs between ISO 50001 and ISO 14001, the end result is that determining significance helps to establish priorities and focus resources in each management system. It is recommended that the energy review for the ISO 50001 system be maintained separately from the environmental aspects information for the ISO 14001 system.

The ENERGY STAR® program does not require SEUs to be determined at defined intervals for reviewing and updating them; something that is required by ISO 50001 and is covered in the guidance in this task.
