The intent of this pilot alternative compliance path is to allow an alternate metric for documenting performance improvement when using Option 1. Whole Building Simulation as the compliance path in LEED's energy efficiency prerequisite and credit. The ACP does not change any other aspect of the referenced prerequisites and credits.
The path allows use of 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., greenhouse gas emissions, primary energy, or Time Dependent Valuation (TDV) Energy as a metric. Typically LEED uses energy cost as a metric.

The intent of this pilot alternative compliance path is to allow an alternate metric for documenting performance improvement when using Option 1. Whole Building Simulation as the compliance path in EA Prerequisite Minimum Energy Performance, EA Credit Optimize Energy Performance, and EA Credit On-site Renewable Energy. The ACP does not change any other aspect of the referenced prerequisites and credits.
Calculate and report all metrics identified below. Refer to the credit specific documentation requirements below for details on the reporting requirements.
Comply with all requirements of Option 1. Whole Building Energy Simulation, except that any of the following metrics may be used in lieu of cost to calculate the percentage improvement:
The percentage of on-site renewable energy shall be calculated using the same metric as is used in EA Prerequisite 2: Minimum energy performance. Renewable energy cost shall be replaced with the renewable energy generation multiplied by the relevant factor associated with the site energy offset by the renewable generation.

Pilot Credit Survey
Provide all standard documentation required for each of the credits submitted. Additionally for every project provide:
Provide supplemental calculations showing how the renewable energy value in the numerator was calculated, including the renewable energy consumption and the factors used for source-to-site, greenhouse gas emissions, primary energy, or TDV energy.
Since we are unable to find greenhouse gas emission factors with a reference to ISO 16346:2014, could we use the greenhouse gas emissions factorsAverage greenhouse gas emissions, in metric tons of carbon equivalent (MtCO2e), per unit of energy for a particular type of energy source as used by the Spanish National Institute for Energy Savings? This institute administers the national building energy certification program as part of the European Energy Performance for Buildings Directive. The greenhouse gas emissions factors used by this Institute do not mention specifically the ISO 16346:2013 standard, as required by this ACP but since these values are used for the national energy certification scheme we believe they are an acceptable reference.
