論文概要:Green building practices have emerged as a critical response to the growing concerns about climate change, energy consumption, and resource scarcity in the construction sector. This study investigates the influence of climate on energy consumption in green buildings, emphasizing the optimization of building envelope insulation and ventilation systems to improve energy efficiency and thermal comfort. By integrating detailed life cycle analysis and simulation modeling, this research evaluates energy-saving potential across different climate zones and latitudes.

The research highlights the challenges faced by green building development, including gaps in policy implementation, technological adaptation, and user behavior. A systematic analysis of internal and external factors influencing green building adoption is conducted, focusing on policy support, economic incentives, certification systems, and occupant interactions. Simulation studies using EnergyPlus software explore the impact of climate and building design on energy consumption, revealing distinct energy-saving strategies suitable for specific latitude regions. In areas above 35° latitude, enhancing insulation significantly reduces heating energy demand, while in regions below 35°, introducing ventilation systems effectively lowers cooling loads.

This study also assesses the applicability of global green building standards, such as ASHRAE climate zoning, to diverse regions like Japan, China, and the United States. The results underline the need for tailored green building strategies that harmonize local climate characteristics, cultural preferences, and construction practices. Recommendations include optimizing thermal insulation, adopting climate-responsive ventilation systems, and aligning global green building certifications with regional needs.

The findings contribute to advancing green building design, policy formulation, and sustainable construction practices. This research provides a roadmap for governments, designers, and stakeholders to enhance the environmental and economic performance of buildings, aligning with global sustainability goals.
