Measuring Energy Reduction for Common Efficiency Improvements


Using data covering over 26,000 properties, the findings indicate that environmental certifications are associated with a reduction in energy consumption of approximately 8% on average, although the impacts of certification vary depending on certification level, program, and tenure.

With energy consumption in commercial real estate expected to increase 19.5% between 2019 and 2050 (EIA), it is important to determine which energy conservation measures (ECMs) are having the most significant impact on building energy performance. Using data from over 26,000 properties throughout the U.S., researchers Eichholtz, Holtermans, and Kok sought to determine whether and to what extent energy efficiency interventions – including environmental building certifications – are connected to lower energy consumption in commercial real estate.
