Post-Occupancy Evaluation (POE) for LEED projects is a valuable process used to assess building performance and occupant satisfaction after the building has been in use. POE measures how well a building meets its original design goals, especially related to sustainability, energy efficiency, and indoor environmental quality. While not mandatory in LEED certification, many building teams conduct POEs to ensure the building maintains its LEED standards and continues to deliver intended benefits.

Key Aspects of LEED Post-Occupancy Evaluation

  1. Energy and Water Performance Monitoring

    • POE often involves ongoing monitoring of energy and water use to verify the building operates within the performance targets set during the LEED certification process.

    • Energy use intensity (EUI), water usage, and carbon footprint are frequently tracked and compared to initial projections, allowing teams to make adjustments as needed.

  2. Indoor Environmental Quality (IEQ) Assessments

    • LEED standards emphasize occupant comfort, including air quality, lighting, acoustics, and thermal comfort. POEs use surveys, sensors, and direct measurements to evaluate how well these systems support occupant well-being.

    • Adjustments can be made based on occupant feedback, such as modifying HVAC settings to improve thermal comfort or adjusting lighting to enhance visual comfort.

  3. Occupant Satisfaction Surveys

    • Occupant surveys are a central part of POE, gathering feedback on aspects like comfort, health, productivity, and overall satisfaction with the building environment.

    • Feedback helps building managers and LEED consultants identify areas where the building may fall short of its LEED goals, such as lighting quality or ventilation, and implement changes.

  4. Commissioning and Re-Commissioning

    • Many LEED buildings undergo periodic re-commissioning to ensure that building systems, like HVAC and lighting, perform as intended over time. Re-commissioning is a process of fine-tuning to maintain efficiency and sustainability.

    • This process can help detect issues that arise post-occupancy, ensuring energy savings and system efficiency remain aligned with LEED standards.

  5. Continuous Improvement for Certification Maintenance

    • For LEED projects seeking to maintain high performance, POE provides insights for continuous improvement and can support recertification efforts if the building seeks LEED for Operations and Maintenance (LEED O+M).

    • Continuous POE feedback can guide future renovations and system upgrades that further enhance sustainability.
       

Benefits of Post-Occupancy Evaluation for LEED
 

  • Enhanced Performance and Efficiency: POE helps identify areas where buildings can improve energy and water efficiency, leading to reduced operational costs.

  • Occupant Health and Productivity: By addressing indoor environmental quality issues, POE ensures that LEED buildings continue to support occupant health and productivity.

  • Sustained LEED Certification Value: Regular evaluations help maintain the value of LEED certification, demonstrating that the building meets ongoing sustainability and occupant satisfaction goals.

Why POE Matters for LEED Projects

POE is increasingly recognized as a best practice in sustainable building management, providing essential feedback that helps buildings meet their LEED goals over the long term. Through ongoing assessment and occupant engagement, POE helps ensure that the benefits of LEED certification, such as energy savings, improved air quality, and occupant well-being, are sustained throughout the building's life.
