<![CDATA[Green buildings can become active nodes in urban energy systems, yet efficiency or annual net-zero balance alone does not ensure service continuity during grid disruptions. This study examines how renewable energy, storage, and load flexibility should be integrated to strengthen urban energy resilience. A directed systematic literature review covered 30 open-access journal articles published from 2020 to 2026. Full texts and DOI records were verified, and evidence was extracted by context, intervention, indicator, finding, limitation, and contribution to anticipation, disturbance absorption, recovery, and adaptation. Renewable energy improves local availability, but its resilience value is constrained by variability and the ability to operate during outages. Storage bridges temporal mismatches between generation and demand, while flexibility reduces peaks, shifts consumption, and prioritizes critical loads. Their combined value is greatest when baseline demand has first been reduced, an energy management system coordinates operation, and outage scenarios are tested. The study proposes autonomy hours, critical-load coverage, unserved energy, islanding success, state-of-charge reserve, and recovery time as key metrics. For Indonesia, implementation should proceed in stages for tropical green buildings and vital facilities through critical-load audits, submetering, commissioning, islanding tests, and district-level energy aggregation.]]>
