Heating ventilation and air conditioning system accounts for over one third of building energy usage, especially public buildings due to large indoor heat source high thermal comfort requirement compared residential buildings. Natural shows application potentials in because its high-efficient effect saving potential dissipation. In this paper, the design is conducted a science museum library with atrium-centered natural consideration. The floor layout, orientation internal structure are optimized make full use space cooling under local climatic conditions. A model established through field tests evaluate flow environment outdoor pressure differences. preliminary results show that Building A's courtyard exhibited overheating issues, likely attributed solar radiation, whereas B's experienced localized cooling, possibly controls. Addressing these concerns necessitates modifications structure. Moreover, both courtyards displayed vertical temperature gradients, emphasizing need effective management influx enhancements shading strategies. To mitigate study proposed three distinct roof models more refined control optimization architectural can achieve maximum energy-saving rate 46.54 %. Furthermore, aligning functional zones areas was recommended enhance overall comfort. findings solutions from anticipated contribute enhancement comfort, efficiency, distribution buildings, catering user requirements while reducing consumption. This research holds significant implications advancing sustainability environmental preservation realm architecture.
