This study aims to evaluate the thermal conditions of wooden houses, a form of vernacular architecture in Grobogan Regency, based on air temperature, relative humidity, and air velocity parameters. A descriptive quantitative approach was employed, involving direct field measurements at five indoor observation points: four at the room's corners and one at its center. Measurements were taken hourly between 06:00 and 18:00 WIB. The results indicate that air temperature rose from morning to midday, peaking at approximately 34.6°C between 13:00 and 14:00 WIB, before dropping to around 31.1–31.4°C by 18:00 WIB. Relative humidity exhibited a pattern inverse to that of temperature: values ranged from approximately 74.7–78.5% in the morning, fell to about 54.1% at midday, and rose again to approximately 73.4–73.6% in the late afternoon. Meanwhile, air velocity was recorded at 0.0 m/s across all observation points and times, indicating that airflow was below the instruments' detection limit. Overall, the measurements reveal that the most critical thermal conditions occurred during midday, characterized by high air temperatures and air velocities below the instruments' detection thresholds. The findings highlight the importance of managing openings and enhancing natural ventilation, specifically through the implementation of cross-ventilation as strategies to improve air circulation within these wooden houses.
