Analisis Lingkungan Termal Ruang Kantor di Gedung Mall Pelayanan Publik Barru

Shapardi Kahir

Abstract


Dalam upaya meningkatkan produktivitas dalam bekerja, ruang kerja perlu mempertimbangkan kenyamanan termal. Dalam ruang kantor di gedung mall pelayanan publik Barru terdapat bukaan yang besar pada area timur kantor yang memungkinkan banyaknya panas radiasi matahari masuk ke dalam ruangan kantor dan juga celah pada sisi ruangan yang menyebabkan menurunnya distriusi udara dingin dalam ruangan kantor. Berdasarkan kondisi ruangan tersebut dapat menjadi salah satu dampak menurunnya kenyamanan termal. Penelitian ini mengambil metode kuantitatif. Tujuannya adalah untuk menganalisis lingkungan termal pada ruangan kantor. Hasil dari nilai kenyamanan termal menggunakan perhitungan dari nilai Predicted Mean Vote (PMV) dan Predicted Percentage of Dissatisfied (PPD) dengan analisis obyektif melalui software Center for Built Environment (CBE) Thermal Comfort Tool lalu disandingkan dengan hasil  simulasi pada aplikasi Ecotect. Hasil penelitian menyatakan bahwa ruang kantor tersebut tidak memenuhi standar kenyamanan termal ASHRAE-55. Pada pengukuran lingkungan termal terdapat nilai MRT rata-rata adalah 27,9 °C dan kelembapan rata-rata 54,8%. Nilai PPD sebesar 32% dan nilai PMV sebesar +1,13 yang menunjukkan sensasi pengguna agak hangat atau slightly warm (SW). Berdasarkan simulasi ecotect menunjukkan bahwa nilai Mean Radiant Temperature (MRT) sesuai dengan hasil pengukuran menggunakan instrument penelitian yaitu pada 28,0 ˚C sampai 29,9 ˚C. Begitu pula nilai PMV (Predicted Mean Vote) ruangan kantor pada 0,99 sampai +1,23
