You can use the VOC budget method to earn this credit by offsetting materials that go over the VOC limit with materials that are under it. The spreadsheet shown here, along with tips in the Getting It Done tab, demonstrates how to perform the budget method. This spreadsheet was completed by Mary Kay, LEED AP BD+C, a LEEDuser reader, and was approved by GBCI on a LEED-NC v2.2 project.
