That an inhabited structure requires thermal management and heat rejection is a matter of basic thermodynamics and everyday observation for any enclosed human habitat, especially in extreme environments. Therefore, a formal citation is not strictly required, though space habitat and EVA literature consistently highlights thermal control as a key design challenge.
The claim that a human base on Mars would need to actively expel excess heat is trivially true by basic thermodynamic principles (humans metabolize energy, equipment generates waste heat, and sealed habitats accumulate thermal energy that must be dissipated to maintain a survivable interior temperature). Therefore, the verdict is COMMON_KNOWLEDGE. Papers [2], [4], and [8] discuss thermal regulation and environmental control systems for space habitats and EVAs, supporting the operational reality of managing heat in space environments.
