Zusammenfassung:Standard peak greenhouse is an adapted design for the humid tropical regions. Analysis of the greenhouse natural ventilation had been conducted using 3D Computational Fluid Dynamics (CFD). The objective of this research was to investigate the greenhouse natural ventilation performance on zero and low windspeed conditions. Solidworks® CFD software was used in this study. Climate data and greenhouse characteristics were used as inputs for the simulation. The results of CFD simulation were presented in 3D of airflow vectors in x, y, and z directions. Results of this study showed the importance of roof vents and sidewalls openings for efficient thermally driven ventilation. Keywords: greenhouse, airflow analysis, natural ventilation, CFD ABSTRAK Greenhouse tipe standard peak adalah hasil adaptasi dari desain greenhouse subtropis untuk kawasan tropis basah. Analisis terhadap ventilasi alamiah greenhouse tipe standard peak telah dilakukan menggunakan Computational Fluid Dynamics (CFD) 3 dimensi. Tujuan penelitian ini yaitu untuk mengetahui kinerja ventilasi alamiah pada greenhouse tipe standard peak pada saat angin tidak bertiup dan saat kecepatan angin di greenhouse luar rendah. Simulasi CFD dilakukan menggunakan perangkat lunak CFD Solidworks®. Data suhu dan karakteristik greenhouse digunakan sebagai input simulasi. Hasil simulasi CFD berupa vektor dan kecepatan aliran udara di dalam greenhouse ditampilkan dalam bentuk visualisasi potongan 3 dimensi arah bidang x, y, dan z. Hasil penelitian menunjukkan pentingnya bukaan ventilasi di atap dan bukaan di dinding greenhouse untuk berlangsungnya ventilasi alamiah akibat gaya termal secara efisien. Kata kunci: greenhouse, aliran udara, ventilasi alamiah, CFD
