Abstract
Pembangunan gedung baru Pasca Sarjana Teknik Fisika merupakan investasi jangka panjang yang sedapat mungkin memberikan kenyamanan bagi setiap civitas akademik dalam pelaksanaan aktivitasnya. Kenyamanan termal dalam ruangan akan meningkatkan produktivitas kerja. Gedung baru Pasca Sarjana Teknik Fisika dilengkapi dengan 8 ventilasi alami berupa jendela denga masing – masing berorientasi barat dan timur. Oleh karena itu, dengan memanfaatkan infrastruktur yang ada maka dilakukan penelitian mengenai prediksi kenyamanan termal dengan ventilasi alami berupa bukaan jendela. Pada penelitian ini dilakukan pengukuran untuk mengetahui besarnya temperatur dinding, kecepatan angin yang masuk melalui jendela, dan radiasi matahari. Selain itu, juga dilakukan simulasi menggunakan Computational Fluid Dynemics (CFD) untuk mengetahui persebaran temperatur dan kecepatan angin didalam ruangan. Penelitian ini memiliki 8 simulasi utama berdasarkan bukaan jendela. Hal ini dilakukan untuk memprediksi tingkat kenyamana termal terhadap penghuni. Dari hasil simulasi dan pengukuran didapatkan variasi 1 menghasilkan kenyaman termal paling rendah dengan PMV 1,97 dan tingkat ketidaknyamanan penghuni (PPD) sebesar 75 %. Sedangkan variasi 4 menghasilkan tingkat kenyamana termal paling tinggi dengan PMV 1,12 dan tingkat ketidaknyamanan penghuni (PPD) sebesar 32 %.

The construction of a new building Post-Graduate Engineering Physics is a long-term investment that as much as possible provide comfort for every academic community in the implementation of its activities. Thermal comfort in the room will increase work productivity. The new Post Graduate Building in Engineering Physics is equipped with 8 natural ventilation windows with each oriented west and east. Therefore, by utilizing the existing infrastructure then conducted research on thermal comfort prediction with natural ventilation in the form of window openings. In this study, the measurements were carried out to determine the mgnitude of wall temperature, the speed of the incoming wind through windows, and solar radiation. In addition, simulations are also performed using Computational Fluid Dynemics (CFD) to determine the spread of temperature and wind speed in the room. This study has 8 main simulations based on window openings. This is done to predict the thermal comfort level of the occupants. From the simulation and measurement results, the variation 1 resulted in the lowest thermal comfort with PMV 1,97 and the Predicted Percentage Dissatisfied (PPD) of 75%. While the 4 variations resulted in the highest thermal comfort level with PMV 1.12 and Predicted Percentage Dissatisfied of occupants (PPD) by 32%.
