First, this paper analyzes the regional climate characteristics of different climate zones in Japan and obtains the potential of natural ventilation in different climate zones in Japan and the main factors of natural ventilation effects in different regions. The results show that there are significant differences in the annual effective ratio of natural ventilation in representative cities in different climate zones in Japan, and this difference is affected by climate conditions and gradually increases from north to south. Cities in District 1 represented by OMU have limited availability of natural ventilation due to the perennial cold climate. Secondly, the annual effective rate of natural ventilation in the representative cities of Districts 2, 3, 4, and 5 is relatively high, about 20%. The annual efficiency of natural ventilation in the representative cities of districts 6 and 7 is slightly higher, about 30%, and has a relatively large potential for natural ventilation. Finally, Naha City, which represents the 8th ward, had the highest natural ventilation annual efficiency at 44.5%.

The study first analyzes regional climate characteristics to determine the potential and key factors influencing natural ventilation across different zones. It reveals significant regional differences in the annual effectiveness of natural ventilation, primarily driven by climate conditions. In northern regions like District 1 (e.g., OMU), the perennial cold climate limits natural ventilation. In contrast, Districts 2–7 have higher annual effective rates of natural ventilation, ranging from 20% to 30%. Southern areas, such as Naha City in District 8, show the highest efficiency, with an annual effectiveness of 44.5%.

Based on the analysis, this paper uses BEST software to simulate indoor temperature and refrigeration energy consumption, studying the impact of natural ventilation on indoor conditions and proposing schemes for different climate zones. Through the study of residential buildings in different climate zones in Japan, it is found that the energy-saving potential is generally between 10% and 40%. As the climate gradually changes from north to south, the energy savings achieved through natural ventilation increase gradually. In terms of energy-saving efficiency, natural ventilation in the first climate zone can reduce cooling energy consumption by nearly half, and the energy-saving effect is remarkable. On the other hand, from the perspective of energy saving, the eighth climate zone has the greatest potential, and its energy saving is about five times that of the first climate zone.

Using BEST software simulations, the study evaluates the impact of natural ventilation on indoor temperature and energy consumption, identifying energy-saving potentials between 10% and 40% across climate zones. Energy savings increase progressively from north to south, with cooling energy consumption in District 1 reduced by nearly half, demonstrating significant efficiency. District 8 offers the greatest energy-saving potential, achieving savings about five times higher than District 1.

The above research results can provide a reference for the planning and design of Japanese detached houses for the use of natural ventilation and the application of natural ventilation in different climate zones.

These findings offer valuable insights for optimizing natural ventilation in detached houses and inform sustainable design strategies tailored to Japan’s varied climate zones.
