Commissioning is required for all energy-related systems that are part of the core-and-shell project. Conversely, if a system is not part of the core-and-shell scope, then commissioning is not required.

If your project is limited to providing a "cold dark shell," you might have no energy-related systems and theoretically may have nothing to commission for this prerequisite, making you exempt from it. Be careful, though, that you're not overlooking anything that could endanger your qualification for the prequisite.
