Population growth and the search for quality of life have boosted the demand for energy and gas emissions, and this aspect is crucial in climate change. The Intergovernmental Panel on Climate Change (IPCC) establishes forward-looking scenarios to assess mitigation or adaptation options in the face of climate change. In this context, this paper aims to assess the impacts of climate change for two extreme scenarios (PRC 2.6 and RPC 8.5) on office buildings in Belo Horizonte by exploring the potential of using natural ventilation in buildings with hybrid ventilation. Projections indicate a significant increase in energy consumption, predicting an increase of 41% by 2050 and 77% by 2080. Concomitantly, the potential use of natural ventilation, with a percentage of window opening of 70% of the time currently, shows reductions of 19% in 2050 and 36% in 2080. These predictions support the need for mitigating actions, alerting designers to improve projects throughout the life cycle of buildings and thus minimize future impacts associated with climate change.
