There is an apparent contradiction in the IECC performance compliance calculations for commercial buildings. Section C401.2.3 essentially says the proposed model energy cost should be 85% or less of the baseline energy cost. Section C407.3 says the proposed model should be less than or equal to the baseline model. This seems to appear in 2012, 2015, and 2018. Has anyone seen a clarification?
