Abstract

Adaptation is essential to manage the problem of climate change. In order to meet the challenge, this paper proposes an adaptive building envelope system that can optimize its configuration by responding environmental changes to achieve new levels of sustainable performance and energy efficiency. Most current adaptive building envelope uses kinetic techniques make its formation transformable. However, the use of kinetic components such as a large amount of interactive motorized system that requires electrical power may alsocause further decrease the building energy efficiency. This paper proposes a camshaft mechanism system for adaptive building envelope that uses less motors, controllers, and sensors. This system uses pre-programmed analysis data of daily solar radiation changes to parametrically drive the number of rotation phase and length of nose (Lobe Lift) that generates the shape of camshaft. The camshaft then controls the values of opening and closing of the building envelope components. The advantages of this system are less energy consumption, less maintenance and lower cost since it uses fewer motors, controllers and wiring. In conclusion, this paper has developed a prototypical tool that facilitates a new approach to energy-efficient kinetic buildings.

Abstract

Makalah ini menjelaskan hubungan alur kerja baru antara program pemodelan CAD 3D (Rhino/Grasshopper) dan simulasi pencahayaan dengan (Radiance/Daysim). Alur kerja perancangan yang sangat efektif dalam Rhino disajikan secara langsung dengan mengekspor geometri, material properties, dan sensor grid ke dalam format Radiance/Daysim untuk menghitung serangkaian indikator performa termasuk peta radiasi matahari serta faktor pendistribusian pencahayaan dalam setahun. Hasil simulasi secara otomatis dikirim kembali ke dalam Rhino menggunakan pemetaan warna. Dengan menggunakan Grasshopper, parameter desain utama seperti ukuran jendela dan deskripsi material dapat diubah secara bertahap dan hasil simulasi dapat dikombinasikan menjadi sebuah simulasi performa bangunan dalam bentuk animasi transformasi parametrik. Desain alur kerja ini telah secara khusus dikembangkan bagi proses perancangan arsitektur dengan menyediakan semua feedback yang sangat berguna bagi perancang secara interaktif dari tahap rancangan skematis sampai tahap pengembangan perancangan.

Abstract

Shading device serves as a shade and protection against negative influences caused by the uncertain external conditions. This article discusses the study of kinetic shading system and evaluates its effectiveness against a wide range of environmental factors and their effects on building. The study performs simulation of thermal factors, day lighting, airflow, and energy generation. Morphological types of shading device to be tested are systems of overhang, folded, horizontal louvre, and vertical louvre. The test results demonstrate that kinetic system obtains more advantages and effectiveness than the standard and static systems do. Therefore, it can be concluded that this study is able to be used as a reference for designing kinetic shading device which is responsive to environmental factors.
