Abstract

Kenyamanan privasi yang terdapat pada unit kamar rusunawa terbentuk melalui batasan ruang yang terdiri dari elemen vertikal dan horizontal. Bukaan jendela dan pintu sebagai bagian dari batasan ruang yang berperan penting dalam mengontrol interaksi antara bagian dalam dengan bagian luar unit kamar. Penerapan bukaan jendela dan pintu pada unit kamar mempengaruhi kuat atau lemahnya batasan ruang dan tingkat privasi yang terdapat pada ruangan tersebut. Berdasarkan teori Hall tentang batasan dan privasi ruang dipengaruhi oleh respon panca indera manusia. Bukaan jendela dan pintu diartikan sebagai bagian yang mengontrol respon indera manusia dalam pembentukan batasan ruang.  Hasil analisis menunjukkan bukaan jendela dan pintu memiliki pengaruh yang erat dalam pembentukan privasi dan kontrol akan parameter privasi ruang. Dalam analisis terdapat tiga dari lima indera yang secara dominan mempengaruhi batasan ruang dan privasi unit kamar rusunawa yaitu penglihatan, aksesibilitas dan proximity atau kedekatan.

Abstract

The growing adoption of window facades in buildings has enhanced the use of daylighting, which has generally been well-received by occupants. However, the effectiveness of daylighting in interior spaces can be influenced by several factors, including the window-to-wall ratio (WWR), glass visible transmittance (VT), and the reflectance of walls, ceilings, and floors. This study investigates how these factors affect indoor average illuminance. To model the indoor lighting environment and adjust these factors, a simulation method using DIALux software was employed. Multiple linear regression analysis was then used to assess the impact of each factor on average illuminance. The results reveal that WWR and VT are the most significant variables, with their increases leading to substantial improvements in illuminance, though the benefits diminish at higher levels. In contrast, ceiling and floor reflectance have minimal effects, with ceiling reflectance being the least impactful. The regression analysis validates the model's high predictive accuracy and highlights the critical role of WWR and VT in achieving optimal lighting conditions.

Abstract

This study examines the performance of cool roofs and green roofs in a tropical climate in Indonesia. It compares a modified pitched roof designed as a cool roof with a flat roof equipped with vegetation functioning as a green roof on single storey building. A simulation method using EnergyPlus is employed to model the building and evaluate roof performance. The evaluation focuses on their efficacy in mitigating heat flux, enhancing thermal comfort, and reducing energy consumption. The results indicate that green roofs can decrease heat flux by up to 91%, lower temperature by up to 13.14°C, and reduce energy consumption by approximately 60%. Meanwhile, cool roofs can achieve up to a 95% reduction in heat flux, a temperature decrease of up to 11.58°C, and an energy savings of up to 55%. Specifically, green roofs demonstrate superior performance in reducing heat gain within the room during daytime. Conversely, cool roofs are more effective in providing thermal comfort during nighttime. For buildings predominantly occupied during the day, the application of green roofs is likely to result in greater energy savings compared to cool roofs.

Abstract

Selubung bangunan memegang peranan penting terhadap konservasi energi di dalam bangunan dan kenyamanan termal interior. Penelitian ini bertujuan mengevaluasi pengaruh desain selubung bangunan terhadap kenyamanan termal di unit apartemen tipe studio di Surabaya yang berorientasi ke timur, dengan fokus pada elemen pembayang, rasio luas jendela terhadap dinding, dan material bangunan. Metode penelitian menggunakan simulasi dengan software Integrated Environmental Solutions-Visual Environment (IES-VE). Simulasi dilakukan pada empat model apartemen dengan variasi desain selubung: Model 1 memodifikasi material dinding dengan nilai U lebih rendah, Model 2 mengurangi rasio jendela terhadap dinding, Model 3 menambahkan elemen pembayang vertikal perforated panel dengan bukaan lebar, sedangkan Model 4 menggunakan perforated panel dengan bukaan kecil. Hasil simulasi menunjukkan bahwa Model 1 dan Model 4 secara signifikan mampu menurunkan suhu operatif dan suhu radian rata-rata, masing-masing sebesar 0,83°C dan 1,01°C pada kondisi puncak. Sebaliknya, Model 3 tidak menunjukkan perbaikan berarti karena balkon sudah berfungsi sebagai pembayang horizontal, sehingga penurunan hanya 0,04°C. Dengan demikian, pemilihan material dinding dengan nilai U rendah serta penggunaan elemen pembayang yang tepat terbukti efektif dalam meningkatkan kenyamanan termal apartemen di iklim tropis.

Abstract

This paper examines the idea of modularity as an extensive framework within the participatory design approach. Modularity is explored not only as a design and construction method but also as a collaboration framework that allows architecture to evolve through collaboration. In exploring the idea, this paper elaborates modularity through a community service design project at Alun-Alun Cemara Miagan, an open space in Miagan Mojoagung, Indonesia, emphasizing a participatory approach that involved local stakeholders and architects in developing a multifunctional public space. Due to the phased funding from the government, the project adopted modular strategies to enable flexible, incremental development aligned with community input. Three modular prototypes were developed: a gate responding to budget and fabrication constraints; a canopy providing adaptable shaded areas; and a building offering spatial flexibility for public functions. Through collaborative ideation in the participatory process, the hands-on engagement and iterative refinement from the community directly informed these design outcomes. This study demonstrates that modularity also supported local industries and addressed funding rhythms, demonstrating its value in both technical and social dimensions. The study also concludes that modular design can foster resilient, adaptable, and resource-efficient public spaces. It contributes to the discourse on community-based architecture and suggests future exploration of digital tools to enhance participatory modular development.
