Aspek kenyamanan pada bangunan menjadi salah satu aspek yang berpengaruh terutama pada bangunan rumah sakit. Beberapa aspek kenyamanan pada bangunan yang memiliki pengaruh besar yaitu kenyamanan termal dan visual. Kenyamanan termal merupakan wujud respons yang menunjukkan kepuasan terhadap lingkungan termalnya, sedangkan kenyamanan visual merupakan reaksi subjektif terhadap kualitas cahaya dalam ruang tertentu. Rumah Sakit Gigi dan Mulut (RSGM) UMY ingin menciptakan suasana keadaan ruang yang nyaman demi efektivitas pemulihan kondisi pasien. Dalam pemantauan aspek kenyamanan bangunan, maka dibangun sistem pemantauan bangunan dengan akuisisi sensor yang memanfaatkan Building Monitoring System (BMS) berbasis Internet of Things (IoT). Penerapan IoT pada bangunan memiliki peranan penting dalam proses pengiriman data pemantauan kepada user. Sistem dibangun dengan akuisisi sensor suhu dan kelembapan SHT11, sensor cahaya BH1750, serta NodeMCU ESP8266 sebagai mikrokontroler. Dari hasil penelitian didapatkan hasil rancang bangun sistem yang mampu bekerja sesuai rentang kenyamanan suhu 17 - 38 ���°C, kelembapan 40 - 60 %RH, serta intensitas cahaya 300 - 500 lux, secara akurat dengan galat akurasi suhu 0,5 ���ºC, kelembapan 3,5 %RH, dan intensitas cahaya 95%, serta mampu menyediakan data sensor siap kirim setiap 30 detik sekali dengan total waktu akuisisi sistem sensor maksimal selama 5 detik.

The comfort aspect of the building is one of the most influential aspects, especially in hospital buildings. Some aspects of comfort in buildings that have a major influence are thermal and visual comfort. Thermal comfort is a form of response that shows satisfaction with the thermal environment, while visual comfort is a subjective reaction to the quality of light in a certain space. The Dental and Oral Hospital of UMY wants to create a comfortable environment for the effective recovery of the patient's condition. In monitoring the comfort aspect of the building, a building monitoring system was built with sensor acquisition that utilizes the Internet of Things (IoT)-based Building Monitoring System (BMS). The application of IoT in buildings has an important role in the process of sending monitoring data to users. The system was built with the acquisition of a temperature and humidity sensor SHT11, light sensor BH1750, and an ESP8266 as a microcontroller. From the research, it is found that the design of a system that is able to work according to the comfort range of temperature 17 - 38 ������°C, humidity range 40 - 60 %RH, and light intensity range 300 - 500 lux, accurately with an accuracy error of temperature 0.5 C, humidity 3.5 %RH, and light intensity 95%, and also capable of providing ready-to-send sensor data every 30 seconds with a maximum total sensor system acquisition time of 5 seconds.
