Intent

To reduce the environmental and economic harms associated with excessive energy use by establishing a minimum level of operating energy performance.

Requirements

Establishment

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.

Performance

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.

Case 1. ENERGY STAR Rating

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 zone.

Case 2. Projects not eligible for ENERGY STAR Rating

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.

Option 1. Benchmark against typical buildings
Path 1. National average data available

Demonstrate energy efficiency performance that is 25% better than the median energy performance of similar buildings by benchmarking against the national source energy data provided in the Portfolio Manager tool.

Path 2. National average data not available

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.

OR

Option 2. Benchmark against historical data

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.

Pilot Credits Available

The following pilots are available as an alternative to the requirements listed above:
EApc67: Energy Jumpstart
EApc106: ISO 50002 Energy Audit
EApc120: District Energy

What does it cost?

Cost estimates for this credit

On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.

Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.

This information is also available in a full PDF download in The Cost of LEED v4 report.

Frequently asked questions

Is there a way to earn this prerequisite without meeting the Energy Star score of 75 or achieving a 25% improvement over the median building?

The answer to this question is available to LEEDuser premium members. Start a free trial »

(If you're already a premium member, log in here.)

The LEED Reference Guide states that Case 1 “is available if the building has an official ENERGY STAR label that was awarded within the 12 months preceding the end of the LEED performance period” but it also seems to indicate that the ENERGY STAR score is required to coincide with the end of the performance period. Can you please help clarify the requirements?
