Your building must achieve an Energy Star score of at least 75 in order to meet this prerequisite and be eligible for LEED certification. This is a big change from LEED 2009, where the minimum score was 69. This update makes LEED v4 more difficult to pursue.
Teams should assess this prerequisite thoroughly before jumping into the LEED certification process. It’s also a good idea to get the official Energy Star label for your building during the performance period to help streamline the LEED review.
If your building isn’t eligible for Energy Star, expect to spend extra time sorting out the appropriate benchmarking path, and in some cases tracking down energy consumption from other comparable buildings.
Yes. If you’re in this boat, check out the Energy Jumpstart pilot credit. This pilot credit is available for LEED v4 projects and requires a 10% improvement over a historic baseline for your building. Meeting the pilot credit won’t necessarily be easy, but it can be a viable option for buildings that are not yet in the top 25% of performers.
If the project has been awarded a label within the last 12 months, it is eligible for the streamlined path. If it does not pursue the official label, then the period upon which the score is based must coincide with the end of the performance period.
To reduce the environmental and economic harms associated with excessive energy use by establishing a minimum level of operating energy performance.
Calibrate meters within the manufacturer’s recommended interval if the building owner, management organization, or tenant owns the meter. Meters owned by third parties (e.g., utilities or governments) are exempt.
Meter the building’s energy use for a full 12 months of continuous operation and achieve the levels of efficiency set forth in the options below. Each building’s energy performance must be based on actual metered energy consumption for both the LEED project building(s) and all comparable buildings used for the benchmark.
For buildings eligible to receive an energy performance rating using the Environmental Protection Agency (EPA) ENERGY STAR® Portfolio Manager tool, achieve an energy performance rating of at least 75. For projects outside the U.S., consult ASHRAE/ASHRAE/IESNA Standard 90.1–2010, Appendixes B and D, to determine the appropriate climate zoneOne of five climatically distinct areas, defined by long-term weather conditions which affect the heating and cooling loads in buildings. The zones were determined according to the 45-year average (1931-1975) of the annual heating and cooling degree-days (base 65 degrees Fahrenheit). An individual building was assigned to a climate zone according to the 45-year average annual degree-days for its National Oceanic and Atmospheric Administration (NOAA) Division..
Projects not eligible to use EPA’s rating system may compare their buildings’ energy performance with that of comparable buildings, using national averages or actual buildings, or with the previous performance of the project building.
Demonstrate energy efficiency performance that is 25% better than the median energy performance of similar buildings by benchmarking against the national source energySource energy is the total amount of raw fuel required to operate a building; it incorporates all transmission, delivery, and production losses for a complete assessment of a building's energy use. data provided in the Portfolio Manager tool.
If national average source energy data are unavailable for buildings of similar type, benchmark against the building site energy data of at least three similar buildings, normalized for climate, building use, and occupancy. Demonstrate a 25% improvement.
If national average source energy data are unavailable, compare the building’s site energy data for the previous 12 months with the data from three contiguous years of the previous five, normalized for climate, building use, and occupancy. Demonstrate a 25% improvement.
