This study evaluates the performance of passive solar strategies in modern office buildings to achieve near-zero energy consumption. The research uses simulation modelling, empirical data collection, and computational analysis to assess the efficacy of these strategies across different climatic regions and building typologies. Performance metrics such as energy savings, indoor environmental quality, and economic viability are systematically evaluated. The study also investigates potential synergies and trade-offs among passive solar strategies to optimize their combined impact on energy efficiency while ensuring occupant comfort and well-being. The findings highlight the significant potential of passive solar strategies in mitigating energy consumption in modern office buildings and provide insights for architects, engineers, and policymakers in designing and retrofitting sustainable office spaces while achieving the efficient strategies that not affect the human comfort along with proposed longitudinal study on energy performance. The research contributes empirical
evidence and a quantitative framework for assessing the tangible benefits of passive solar strategies in the pursuit of sustainable building design and operation.
