Performing LEED Green Power Calculations

To calculate your project’s required green power purchase quantity for the Green Power credit, choose one of the methods below according to your project type and calculation method.

For LEED-NC and Schools projects

Calculation Based on Design Energy Cost

Total Required Green Power Quantity = Design case total electricity usage  X  35%  X  2 years

• The Design case total electricity usage may be obtained from EAc1 calculations or energy model results.
• Confirm accurate threshold percentage to achieve desired LEED points.
• LEED-NC and Schools projects will calculation 35% of the electricity use to achieve EAc6.
• Exemplary performanceIn LEED, certain credits have established thresholds beyond basic credit achievement. Meeting these thresholds can earn additional points through Innovation in Design (ID) or Innovation in Operations (IO) points. As a general rule of thumb, ID credits for exemplary performance are awarded for doubling the credit requirements and/or achieving the next incremental percentage threshold. However, this rule varies on a case by case basis, so check the credit requirements. will be achieved for all projects that purchase 100% of their electricity use from renewable sources.
