Intent
To support energy management and reduce environmental and economic harms associated with excessive energy use by reducing greenhouse gas emissions and achieving higher levels of operating energy performance.
Requirements
Have permanently installed energy meters or submeters that measure total building energy consumption (electricity, natural gas, chilled water, steam, fuel oil, propane, etc). Utility-owned meters capable of aggregating total project energy use are acceptable. For Interiors projects, have permanently installed sub-meters that measure all electricity and fossil fuels for equipment within the project scope. Alternately, interiors projects may pro-rate energy use, using occupancy and base building energy use over twelve consecutive months. Calibrate meters within the manufacturer’s recommended interval if the project owner, management organization, or tenant owns the meter. Meters owned by third parties (e.g., utilities or governments) are exempt. Measure the project’s energy use on a monthly basis for twelve consecutive months (one full year). Use the twelve months of energy use data to obtain an energy performance score. LEED points are based on project energy performance across two metrics: greenhouse gas emissions and source energy. For each metric, obtain a minimum performance score of 40 and associated minimum points in order to meet the prerequisite.

GHG Emissions Score:
The GHG emissions score rates the building’s total greenhouse gas emissions against the total greenhouse gas emissions of comparable high-performing buildings. The score is a value from 1-100 based on the project’s GHG emissions per occupant and GHG emissions per floor area.GHG Emissions Score calculation
To calculate a GHG emissions score, the following data is required:- Annual Energy consumption (kBtu), with monthly or daily totals and distinguished by fuel type
- Gross floor area (sq. ft. or sq. m.)
- Weighted occupancy
- Weighted operating hours
- Outside air temperature
- Location
Table 4. Operating hours adjustment factor
GHG emissions per occupant is calculated by dividing the adjusted GHG emissions by the weighted occupancy Equation 3. GHG emissions per occupant = adjusted GHG emissions / weighted occupancy GHG emissions per floor area is calculated by dividing the adjusted GHG emissions by the gross floor area. Equation 4: GHG emissions per floor area = adjusted GHG emissions / gross floor area The project’s calculated GHG emissions per occupant and GHG emissions per floor area are input into the energy scoring function for the specific project type. The energy scoring function was developed using energy consumption data from high-performing buildings. The data set includes LEED buildings that shared their energy consumption data with USGBC as part of the whole-building energy and water usage requirement.Source Energy Score:
The source energy score rates the building’s total energy consumption against the total energy consumption of comparable high-performing buildings. The score is a value from 1-100 based on the project’s source energy consumption per occupant and per floor area. Source Energy Score calculation To calculate a source energy score, the following data is required:- Annual Energy consumption, with monthly or daily totals and distinguished by fuel type
- Gross floor area (sq. ft. or sq. m.)
- Weighted occupancy
- Weighted operating hours
- Outside temperature

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.
