Maximizing Your ENERGY STAR Score: Achieving Top Energy Performance for Commercial Buildings

Understanding the ENERGY STAR Score

Achieving superior energy performance requires a precise evaluation of a building’s operational data, and the ENERGY STAR Score is a proven metric to gauge this efficiency. The ENERGY STAR Score provides an objective rating, ranging from 1 to 100, that compares a building’s energy performance to similar facilities nationwide. A high score not only signals operational excellence but also translates into reduced operating costs, increased property value, and enhanced marketability. This guide presents a comprehensive framework for maximizing your ENERGY STAR Score, with actionable strategies based on ENERGY STAR Portfolio Manager metrics, such as Energy Use Intensity (EUI) and other key performance indicators. In addition, the expertise of Benchmarking Buildings, which has successfully benchmarked thousands of commercial properties, is highlighted as an essential partner in achieving top energy performance.

What is the ENERGY STAR Score?

The ENERGY STAR Score is a standardized metric used to evaluate and compare the energy performance of commercial buildings. It is calculated on a scale from 1 to 100, where 50 represents median performance. A building that scores 75 or higher is considered a top performer. The score is derived from a range of data points that capture various aspects of energy consumption and efficiency. The calculation adjusts for factors such as climate, building size, and operating hours to ensure that comparisons between properties are fair and meaningful. A robust ENERGY STAR Score is not only an indicator of current performance but also serves as a benchmark for setting future energy efficiency goals.

Key Performance Metrics Behind the Score

Energy Use Intensity (EUI)

Energy Use Intensity (EUI) is a critical metric that measures the amount of energy consumed per unit area of a building, typically expressed in kBtu per square foot. EUI provides a clear indicator of a building's energy efficiency by allowing direct comparisons between buildings of different sizes and uses. A lower EUI signifies more efficient energy use. Property managers can leverage EUI to identify trends over time and evaluate the impact of energy conservation measures. Consistent tracking of EUI is fundamental for continuous improvement in energy management.

Other Critical KPIs

In addition to EUI, several other key performance indicators (KPIs) contribute to the ENERGY STAR Score. These include:

• Utility Data: Detailed records of energy consumption from utility bills provide the raw data needed to calculate performance metrics.
• Cost Savings: Analysis of energy expenditure relative to consumption helps quantify the financial benefits of energy efficiency improvements.
• Emissions Data: For some properties, tracking greenhouse gas emissions is integral to demonstrating environmental performance.
• Operational Efficiency: Data on equipment performance, such as HVAC and lighting systems, further refines the overall energy performance picture.

Collectively, these KPIs enable property managers to conduct a comprehensive assessment of energy efficiency and identify the most impactful areas for improvement.

Strategies to Improve Your ENERGY STAR Score

Conducting a Detailed Energy Audit

A thorough energy audit is the foundation of any effective energy management strategy. By systematically reviewing utility bills, operational data, and building systems, property managers can pinpoint inefficiencies that adversely affect the ENERGY STAR Score. An energy audit should include:

• A review of historical energy consumption data.
• An analysis of peak demand periods and load profiles.
• An assessment of building systems such as HVAC, lighting, and insulation.
• Identification of opportunities for retrofits or operational changes.

The audit not only highlights immediate opportunities for cost savings but also informs the development of long-term energy management plans. A meticulous approach to auditing ensures that the baseline data used in ENERGY STAR Portfolio Manager is accurate and reliable.

Optimizing Building Systems and Upgrades

Enhancing the performance of building systems is essential for improving the ENERGY STAR Score. Key areas of focus include:

HVAC, Lighting, and Envelope Improvements

Upgrading the HVAC system can yield significant energy savings, particularly when modern, energy-efficient technologies replace outdated equipment. In parallel, improvements in lighting—such as retrofitting with LED technology—reduce energy consumption while enhancing the quality of indoor illumination. Additionally, optimizing the building envelope through better insulation and window upgrades can reduce heating and cooling loads, leading to improved overall energy performance.

Each of these upgrades contributes directly to a lower EUI and a higher ENERGY STAR Score. Property managers must assess the cost-effectiveness of each potential upgrade and prioritize projects that deliver the highest energy savings relative to investment.

Leveraging Renewable Energy Options

Integrating renewable energy sources into a building’s energy portfolio can significantly enhance its ENERGY STAR Score. Solar photovoltaic (PV) panels, wind turbines, or geothermal systems can provide clean, sustainable energy that offsets conventional electricity consumption. The use of renewable energy not only reduces overall energy use but also contributes to lower greenhouse gas emissions—a critical factor in many energy performance evaluations.

Renewable energy investments can be supported through local utility incentives and federal or state grants. When combined with traditional energy efficiency measures, the integration of renewable energy creates a comprehensive strategy for long-term sustainability and improved operational performance.

Utilizing ENERGY STAR Portfolio Manager Effectively

Effective use of ENERGY STAR Portfolio Manager is essential to monitor and improve energy performance. Best practices for using the tool include:

Automating Data Submission

Many commercial buildings benefit from automated data submission, which minimizes manual entry errors and ensures timely updates of performance metrics. Integration with utility providers through web services allows for seamless data transfer directly into Portfolio Manager. This automation not only streamlines the benchmarking process but also ensures that property managers have access to the most current data available.

Setting and Tracking Energy Performance Goals

Once baseline data is established, property managers should set clear, measurable energy performance goals. These targets should be realistic yet ambitious, reflecting the building’s potential for improvement. Regular monitoring of key metrics such as ENERGY STAR Score and EUI allows managers to track progress over time. Goal setting is most effective when it is integrated into a broader continuous improvement strategy that includes periodic audits, performance reviews, and updates to operational practices.
