Simplifying the Complex Nature of Portfolio-Wide Energy Efficiency Assessments on Leased Commercial Office Space


The implementation of an energy efficiency strategy will reinforce an organizations commitment to environmental sustainability while reducing operating costs and offsetting future renewable energy purchases. As buildings move towards the era of smart and connected technologies, there remains a portion of the commercial building portfolio that continues to exhibit opportunities for capturing low hanging measures. By leveraging portfolio-wide resource consumption data, modern analytical outlier practices, a specialized process for statistical selection, and a simple yet effective interview process, WSP’s approach for leased space energy assessments resulted in an estimated 3-8% of otherwise untapped energy efficiency within a portfolio of offices. Recognizing that leased spaces present challenges related to financial and operational efficiency measures, this project embraced the benefits of behavioral change, data management, and emerging technologies as a means for more effective management practices. To facilitate the implementation of efficiency recommendations, WSP identified potential financial partnership mechanisms that allow for recognition of financial cost savings and carbon reductions while overcoming some for barriers associated with the possibility of split incentives  attributed to efficiency project implementation.
