Rising global temperatures and deteriorating urban air quality underscore the urgent need for effective carbon removal technologies. Direct Air Capture (DAC) offers a promising solution, but its high energy demand raises concerns about overall sustainability. This study evaluates the environmental performance of a novel system that integrates DAC with Heating, Ventilation, and Air Conditioning (HVAC) infrastructure to improve energy efficiency and reduce environmental impact. A cradle-to-gate life cycle assessment (LCA) is conducted based on numerical modeling of the DAC-HVAC system. The integrated system exhibits significantly reduced environmental impacts compared to a standalone DAC unit.
