In the CBCI EDGE curriculum, a "required" measure refers to a measure that must be implemented in the project as part of meeting the EDGE certification criteria. Required measures are mandatory and cannot be excluded if the project is to achieve certification. Their implementation is verified during the design audit and confirmed during the site audit stage.
Option A is incorrect because simply assessing a measure is not sufficient; a required measure must be physically incorporated into the building design and construction. Option C is incorrect because a Special Ruling Request is used in exceptional cases to seek clarification or alternative compliance pathways, but required measures do not depend on SRR approval to be implemented. Option D is also incorrect because the concept of meeting or exceeding the baseline relates to performance calculations for savings, not specifically to the definition of a required measure.
Therefore, under the EDGE framework, a required measure is one that must be implemented in the project to comply with certification requirements, making option B the correct answer.
