Percentage of all City Buildings eligible for an ENERGY STAR score with a score greater than or equal to 75

Status

The EPA Energy Star Portfolio Manager is a nationally utilized online tool to measure and track energy and water consumption, as well as greenhouse gas emissions. The score, which ranges from 1 to 100 indicates the energy efficiency of a particular building. The score represents the percentile that a particular building falls in compared to similar buildings across the nation. A building with a score of 75 indicates that that building operates more energy efficiently than 75% of similar buildings.

Trending

Over the four years that BSD has collected data on this measure, the percentage of eligible City buildings with an Energy Star score of 75 or greater has remained stagnant. The long-term goal of 50% will require improve facility operations and, more importantly, financial investment in energy efficiency technology and facility modifications.

Measure Details and Definition

1) Definition: This measure evaluates the percentage of all City buildings eligible for an ENERGY STAR score with a score greater than or equal to 75. The score, which ranges from 1 to 100 indicates the energy efficiency of a particular building. The score represents the percentile that a particular building falls in compared to similar buildings across the nation.

2) Calculation method: The ENERGY STAR Portfolio Manager module utilizes an algorithm to score each facility based on its relative performance to other facilities of the same size and type. These scores are then exported and summarized in a data table and the percentage of facilities that achieve a score of 75 or higher can be calculated.

3) Data Collection Process:  The Office of Sustainability captures all raw utility data and imports this data into the ENERGY STAR Portfolio Manager. The resulting scores are then exported and summarized in a data table.       

4) Measure Target Calculation: The long-term goal of 70% represents a challenging, yet achievable, goal provided the necessary resources are dedicated to it. Reaching 70% will require ongoing efforts to monitor and improve energy efficiency and usage across the City's facility portfolio. The ability to make these improvements hinges on the funding and grant opportunities that are available.  

5) Frequency Measure is Reported:  Annually (Fiscal Year)
