Abstract

Rusun is a simple flat categorized as Affordable Housing (AH), which means it requires economic energy efficiency and optimal Natural Ventilation (NV) to manifest and provide comfort for users. This research will review the effect of spatial configuration on NV conditions of Rusun unit in terms of the condition of wind flow (WF) and wind speed (WS) value in each residential room by simulation method.The condition of the unit is on the 10th floor and height of 31.5m with an outdoor WS of 1.62 m/s in three different space configurations. It was found from the simulation that residential space that has direct access from openings both inlet and exit (outlet) has a more optimal WF and WS. From the WF condition and WS value following the needs of residential user activities, it is expected to optimize NV in Rusun units and in line with that, can realize energy-efficient Rusun buildings in terms of occupancy.

Abstract

Economic growth in ASEAN countries encourages significant urbanized growth. In line with the growth of urbanization, large swathes of residential buildings have been constructed in urban areas, especially, in the case of Indonesia, through the government's 1000 rusun (high-rise affordable housing) development program in Jakarta. In order to reduce energy consumption and create a sustainable rusun, a passive strategy is needed in the form of natural air conditioning through optimized natural ventilation in these buildings. In this study, testing was conducted on Rusun Rorotan in Jakarta, from two wind source directions (north and northwest) with five void decks configuration samples each, in order to determine wind flow and wind speed patterns in the Rusun area. For this purpose, the wind tunnel simulation method using the Butterfly plugin in Grasshopper was employed. These results should provide a reference for future residential property developers, especially in the scope of other countries in ASEAN, which have similar climatic conditions to that of Indonesia.

Abstract

With the lack of clarity on when the Covid-19 pandemic will end, there is a demand for a new design approach to the configuration of circulation paths in public open spaces. a design approach that can break up the crowd and form a space with a low-density pattern can be a new form of adaptation to new social arrangements and conditions after the pandemic. Therefore, it is necessary to conduct research through simulations related to the spatial aspects of the configuration of public open spaces and the activities in them, to see how the form of space and the elements supporting activities in accommodating activities, and predicting what forms of intervention are appropriate in accommodating activities in the new normal period. This study uses an experimental-simulative method through simulation of space syntax on the circulation path through the DephtmapX 0.50, to identify opportunities for regeneration of new designs to respond to the spatial potential of existing urban areas. It can be seen from the results of the space syntax simulation that with the addition of activity spaces and new circulation paths with strong symmetry, it can form a more even distribution of visitors to all parts of public open spaces.

Abstract

ABSTRAK. Seiring dengan pertumbuhan jumlah penduduk di Indonesia peningkatan akan kebutuhan layanan kesehatan juga semakin meningkat, khususnya kebutuhan rumah sakit. Rumah Sakit Paru dr Ario Wirawan (RSPAW) Salatiga saat ini sedang dalam tahap perencanaan untuk pembangunan. Pembangunan rumah sakit ini akan mempengaruhi kepadatan bangunan yang ada di kawasan eksisting. Berdasarkan penelitian terdahulu bahwa densitas bangunan memiliki pengaruh besar terhadap iklim mikro disekitarnya khususnya terhadap permeabilitas angin pada kawasan. Penelitian ini bertujuan untuk mengetahui pengaruh berbagai densitas bangunan untuk mengoptimalkan permeabilitas kawasan agar sirkulasi udara dapat terdistribusi dengan optimal pada kawasan Rumah Sakit Paru dr Ario Wirawan. Penelitian ini akan menggunakan metode simulasi dengan Rhinoceros sebagai perangkat permodelan yang akan dilanjutkan dengan metode analisis CFD dari perangkat tambahan Grasshopper. Selanjutnya, untuk melakukan analisis simulasi CFD akan menggunakan salah satu perangkat bagian dari Ladybug Tools yaitu Butterfly. Hasil penelitian menunjukkan apabila pada kawasan RSPAW melakukan pengembangan dengan menambah kepadatan bangunan tanpa mempertimbangkan permeabilitas akan menurunkan kecepatan angin rata-ratanya. Permeabilitas yang dianjurkan adalah minimal 70% untuk mencapai kategori dapat diterima berdasarkan standar kenyamanan angin. Sedangkan untuk permeabilitas dibawah 70% dianggap kurang menguntungkan. Meskipun begitu, permeabilitas minimal 85% telah terbukti lebih baik pada kedua arah datang angin untuk dapat masuk kategori dapat diterima. Kata kunci: rumah sakit, permeabilitas udara, kepadatan bangunan, iklim mikro ABSTRACT. Along with population growth in Indonesia, the need for health services is also increasing, especially for hospitals. Dr. Ario Wirawan's Pulmonary Hospital is currently in the process of planning to develop. The development of this hospital will affect the density of existing buildings in the existing area; based on previous research, the density of buildings significantly influences the surrounding microclimate, especially wind permeability in the area. This study aims to determine the effect of various building densities to optimize the permeability of the area so that air circulation can be optimally distributed in the area of Dr. Ario Wirawan Lung Hospital. A simulation method with a quantitative approach will be used. This research will use Rhinoceros as a modeling tool followed by the CFD analysis method from Grasshopper enhancement.Furthermore, this research will use Ladybug Tools and Butterfly plugin to analyze the CFD simulation. The results show that if the RSPAW area develops by increasing the density of buildings without considering the permeability will reduce the average wind speed. The recommended permeability percentage is at least 70% to reach an acceptable category based on wind comfort standards, as more than 70% is acceptable. However, the permeability of at least 85% is better in both wind directions, being acceptable. Keywords: hospital, wind permeability, building density, microclimate
