Abstract

Penelitian ini merupakan studi perbandingan hunian sementara dengan pendekatan prefabrikasi. Penelitian ini dilakukan berdasarkan kebutuhan akan preseden desain hunian sementara dengan pendekatan prefabrikasi yang dapat tetap mendekati standar hunian sementara pemerintah (setidaknya mendekati spesifikasi dan anggaran). Penelitian ini akan membandingkan spesifikasi dan anggaran dari 9 model hunian sementara prefabrikasi berdasarkan standar hunian sementara Nasional Indonesia. Tujuannya adalah untuk menemukan preseden untuk hunian sementara prefabrikasi yang lebih mendekati standar hunian sementara di Indonesia. Metode dalam penelitian ini menggunakan beberapa metode yaitu kuantitatif dalam deskripsi data awal, kualitatif dalam penilaian akhir, yang dipadukan dengan perbandingan skor yang diberikan pada setiap shelter. Hasil dari penelitian ini adalah ditemukannya dua tipe hunian sementara prefabrikasi yang cukup mendekati standart hunian sementara Nasional Indonesia berupa sampel F 33 titik dan sampel E 30 titik. Hasil ini banyak dipengaruhi oleh dua faktor: pemilihan bahan dan penilaian poin di tempat penampungan.

Abstract

Traditional buildings are one type of structure that can adapt to a dynamic environment. Some functions of the building’s spaces have been changed to the new requirements, but the building's overall shape has been preserved. The purpose of this study was to examine and determine the differences in perceived thermal comfort values ​​between occupants and visitors inside the building. Using the observation method and analyzing the data through PMV-PPD and correlating with the Adaptive method in the Center for the Built Environment (CBE) Thermal Comfort Tool Website, it shows that there are differences caused by the environmental climate that do not match the PMV standard from ASHRAE. This study also has shown a difference of 18% between the PMV value of visitors to occupants, where there are past factors that influence this difference, and also a difference of 0.58 between the PMV value of Fanger and Sugini theory (comparison between general theory that is often used with the local theory that has been researched), because of Indonesians' heat tolerance. In this study, it was found that there are variables that are not needed in the adaptive method approach of naturally ventilated buildings, namely the humidity in buildings that are in tropical and humid areas. The reason for this is that the effect of moisture on the thermal sensation is insignificant, and it can be neglected.

Abstract

Natural Ventilation is a sustainable passive strategy for enhancing thermal comfort and reducing energy consumption in buildings with fluctuating occupancy levels, such as mosques. This study investigates the effects of varying inlet-to-outlet opening ratios using different schemes, simulated through Computational Fluid Dynamics (CFD) with the RANS model via OpenFOAM (Butterfly plugin in Grasshopper). Based on urban wind profiles, this research evaluates wind-driven Ventilation under isothermal conditions. The simulation examines five inlet-outlet opening ratios (ranging from 1:1 to 1:5), two inlet configurations (single vs. double), five building lengths (5×10, 10×10, 15×10, 20×10, and 25×10 m), and three building heights (3 m, 4 m, and 5 m). Results indicate that an opening ratio of 1:3 provides the optimal balance between airflow efficiency and thermal stability, particularly concerning solar radiation effects. The single-inlet configuration yields higher air velocity at standing height (1.1 m), whereas the double-inlet setup promotes a more uniform vertical airflow distribution. Increasing building height enhances airflow due to reduced ground-level resistance, while elongated floor plans (over 10 m in length) experience flow stagnation in the central zone. These findings underscore that optimal natural ventilation in mosques depends on opening ratios, spatial proportions, and inlet configurations. Such insights contribute to climate-responsive mosque design, especially in dense urban environments, supporting energy-efficient and comfortable indoor conditions during congregational prayers.

Abstract

Abstract: Rapid urbanization demands significant growth in basic infrastructure, particularly in affordable housing. Concurrently, the escalating development necessitates an increased demand for energy. Among the strategies to mitigate high energy consumption is the optimization of building envelopes, such as roofs which experience the highest solar gain in tropical regions. This research aims to identify the effect of inclination angle and material of roof on thermal performance in tropical climate. Five configurations of roof inclination angles with various materials, facing both North-South and East-West orientations, were analyzed using Ladybug and Honeybee Tools. The results revealed that roof inclination angle, material significantly affect the average conduction. In a sequential order, the roofing materials with the lowest average conductivity values are concrete tiles, clay tiles, PVC roofs, and metal roofs. A greater inclination angle correlates with a lower average conductivity value, indicative of enhanced thermal performance, and vice versa. Roofs with inclination angles > 0°, featuring the same material, oriented North-South exhibit lower average conductivity compared to those facing East-West.Keyword: Thermal Performance, Roof Inclination Angle, Roof MaterialsAbstrak: Urbanisasi yang pesat menuntut pertumbuhan infrastruktur dasar yang signifikan, khususnya perumahan yang terjangkau. Pada saat yang sama, peningkatan pembangunan memerlukan peningkatan kebutuhan energi. Salah satu strategi untuk memitigasi konsumsi energi yang tinggi adalah optimalisasi selubung bangunan, seperti atap yang memperoleh perolehan sinar matahari tertinggi di wilayah tropis. Penelitian ini bertujuan untuk mengetahui pengaruh sudut kemiringan dan material atap terhadap kinerja termal pada iklim tropis. Lima konfigurasi sudut kemiringan atap dengan material berbeda, menghadap orientasi Utara-Selatan dan Timur-Barat, dianalisis menggunakan Ladybug dan Honeybee Tools. Hasil penelitian menunjukkan bahwa sudut kemiringan atap, material berpengaruh nyata terhadap konduksi rata-rata. Secara berurutan, bahan atap dengan nilai konduktivitas rata-rata paling rendah adalah genteng beton, genteng tanah liat, atap PVC, dan atap metal. Sudut kemiringan yang lebih besar berkorelasi dengan nilai konduktivitas rata-rata yang lebih rendah, yang menunjukkan peningkatan kinerja termal, dan sebaliknya. Atap dengan sudut kemiringan > 0°, dengan bahan yang sama, berorientasi Utara-Selatan menunjukkan konduktivitas rata-rata lebih rendah dibandingkan atap yang menghadap Timur-Barat Kata Kunci: Kinerja Termal, Sudut Kemiringan Atap, Material Atap
