Verifying Savings and Preventing Snapback: Strategies for Sustained Energy Efficiency

Commercial properties face ongoing challenges to maintain energy efficiency improvements after initial upgrades are implemented. Even when building systems are upgraded and operating more efficiently, factors such as equipment degradation, operational drift, and inadequate maintenance can lead to a gradual reversion—commonly known as “snapback”—to higher energy consumption levels. Ensuring that the benefits of energy efficiency measures persist over time is critical for maximizing return on investment (ROI) and maintaining operational excellence.

The Importance of Sustained Energy Efficiency

Achieving energy efficiency improvements in commercial buildings is only the beginning; the true value lies in maintaining those gains over time. Without proper verification and ongoing management, the benefits of energy conservation measures (ECMs) can diminish. Ensuring sustained energy savings is essential for lowering operating costs, optimizing asset management, and achieving a solid ROI.

Continuous monitoring and proactive maintenance enable building operators to track energy performance and quickly address any issues that could lead to snapback. A data-driven approach, rooted in robust benchmarking, ensures that energy-saving measures are not one-time improvements but become an integral part of long-term operational strategy.

The Role of Benchmarking in Sustaining Savings

Benchmarking transforms raw energy data into actionable insights by establishing baseline performance metrics and continuously tracking changes over time. Key performance indicators (KPIs) such as Energy Use Intensity (EUI) allow property managers to detect deviations from expected savings, signaling when corrective action is needed. By using benchmarking as a foundation for ongoing monitoring, managers can maintain a high level of energy efficiency and prevent efficiency losses due to operational drift or equipment wear.

Understanding Snapback in Energy Efficiency

What is Snapback?

Snapback refers to the gradual reversal of energy savings following the implementation of efficiency measures. Despite initial improvements, energy use can creep back toward previous levels if systems are not maintained or if operating conditions change. Snapback undermines the long-term value of investments in energy efficiency and can result in higher operating costs over time.

Common Causes of Snapback

Inadequate Maintenance

Regular maintenance is essential to ensure that systems continue to operate at peak efficiency. When maintenance schedules are neglected or equipment falls out of calibration, energy savings can diminish. For example, HVAC systems that are not periodically serviced may operate less efficiently, leading to increased energy use.

Operational Drift

Over time, changes in building occupancy or alterations in operational practices can cause energy performance to drift. Without periodic review and adjustment, the efficiency gains achieved through initial upgrades may not be sustained. Variations in building usage, such as extended operating hours or changes in tenant behavior, can also contribute to snapback.

Lack of Continuous Monitoring

Without a system to continuously track energy performance, early signs of snapback may go undetected. Property managers need real-time insights to identify and address inefficiencies as they emerge. A robust monitoring system is crucial to ensure that energy savings remain stable and that corrective actions can be taken promptly.

Strategies to Verify Energy Savings

Continuous Monitoring and Real-Time Data Analysis

Automated Data Collection Systems

Implementing automated data collection systems is the first line of defense against snapback. These systems capture energy usage data in real time, minimizing errors associated with manual data entry. With automated data collection, property managers have immediate access to up-to-date energy performance metrics, allowing for timely analysis and action.

Real-Time Dashboards and Alerts

Deploy real-time dashboards that display key energy performance indicators such as EUI and operational costs. These dashboards can be configured to send automated alerts if energy consumption deviates from expected patterns. For example, if a building’s energy usage begins to increase unexpectedly, alerts allow property managers to investigate and address the issue before significant savings are lost.

Regular Energy Audits and Performance Reviews

Scheduling Periodic Energy Audits

Energy audits are comprehensive assessments that verify the effectiveness of energy conservation measures. Scheduling regular audits allows property managers to compare current energy usage against baseline data, ensuring that efficiency improvements remain intact. Audits can identify maintenance issues or operational changes that may have contributed to a reduction in savings.

Comparing Pre- and Post-Upgrade Performance

By comparing energy performance data from before and after the implementation of ECMs, managers can quantify the actual savings achieved. This process provides clear evidence of the ROI and helps verify that the energy upgrades are delivering sustained benefits. Regular performance reviews, combined with audit findings, offer a comprehensive view of the building’s energy efficiency over time.

Implementing Predictive Maintenance Strategies

Leveraging Predictive Analytics

Predictive analytics involves analyzing historical data to forecast future equipment performance. By identifying patterns that signal potential degradation or failure, property managers can schedule proactive maintenance before issues arise. This approach minimizes downtime and prevents the gradual erosion of energy savings, ensuring that ECMs continue to deliver high levels of efficiency.

Aligning Maintenance Schedules with Performance Data

Integrate maintenance schedules with continuous monitoring systems so that regular servicing and calibration of equipment are aligned with energy performance trends. By systematically maintaining systems based on data insights, operators can sustain energy efficiency improvements and avoid the pitfalls of snapback.

Preventing Snapback Through Proactive Strategies

Establishing a Robust Energy Management Program

Comprehensive Measurement and Management Systems

A successful energy management program involves a holistic approach that integrates continuous measurement, performance tracking, and proactive maintenance. Establishing a system that routinely collects and analyzes energy data is essential for setting performance targets and tracking progress. This comprehensive approach ensures that energy efficiency improvements are not temporary but are embedded within daily operations.

Implementing Standard Operating Procedures (SOPs)

Developing and enforcing SOPs for routine maintenance and energy management is crucial for preventing snapback. SOPs standardize best practices across your portfolio, ensuring that every building follows the same high standards. Regular training and updates to these procedures further reinforce the commitment to sustained energy efficiency.

Leveraging Best Practices and Continuous Training
