Abstract
Ruangan yang dapat memasukkan sinar matahari secara langsung dapat dikatakan baik dalam perancangan, tetapi jika berlebihan sinar matahari yang masuk dapat mengakibatkan silau dan panas pada pengguna ruangan. Perilaku pengguna ruangan yang sangat umum terjadi untuk mengatasi silau dan panas dari matahari adalah menutup tirai jendela dan menyalakan lampu ruangan. Perilaku ini, tanpa disadari sudah memboroskan energi listrik, karena sebetulnya kondisi di luar ruangan masih terdapat sinar matahari yang cukup terang untuk menerangi ruangan tersebut dan dengan sumber daya yang terbarukan. Penggunaan sun shading bergradasi dapat menjadi solusi untuk mengurangi cahaya yang berlebih dari sinar matahari sekaligus mengurangi panas yang dipancarkan. Bentuk sun shading yang umum digunakan di beberapa bangunan di Indonesia adalah kotak dan bulat. Metode penelitian yang digunakan dalam penelitian ini adalah percobaan dummy room dengan menggunakan Sketch Up guna melihat visibilitas sun shading dan percobaan dummy room dengan Autodesk Ecotect Analysis guna menentukan tingkat iluminasi di dalam ruangan. Tujuan dari penelitian ini adalah menemukan desain bentuk sun shading perforated bergradasi yang paling efektif untuk mengurangi silau dalam ruangan dan paling efektif tingkat visibilitasnya. Hasil dari penelitian ini adalah menemukan desain sun shading perforated bergradasi lingkaran yang paling efektif dibandingkan desain sun shading perforated bergradasi kotak untuk mengurangi silau dalam ruangan dan perbandingannya tanpa menggunakan sun shading perforated bergradasi. Dari simulasi menggunakan software sketchup, ditemukan tingkat visibilitas sun shading perforated bergradasi kotak dan bulat sama-sama memberikan tingkat visibilitas yang cukup baik.
LIGHTING LEVEL EFFICIENCY AND VISIBILITY GRADIENT PERFORATED SUN SHADING IN SQUARE SHAPE AND ROUND
A room that can enter direct sunlight can be said to be good in design, but if excessive incoming sunlight can cause glare and heat to room users. The behavior of room users that is very common to overcome the glare and heat from the sun is to close the window curtains and turn on the room lights. This behavior, without realizing it, has wasted electrical energy, because in fact the conditions outside the room are still bright enough sunlight to illuminate the room and with renewable resources. The use of graded sun shading can be a solution to reduce glare from the sun while reducing the heat emitted. The forms of sun shading that are commonly used in several buildings in Indonesia are square and round. The research method used in this research is a dummy room experiment using Sketch Up to see the visibility of sun shading and a dummy room experiment with Autodesk Ecotect Analysis to determine the level of illumination in the room. The aim of this research is to find the most effective graded perforated sun shading design for reducing indoor glare and the most effective level of visibility. The results of this research were to find that the circular graded perforated sun shading design was the most effective compared to the square graded perforated sun shading design for reducing indoor glare and the comparison was without using graded perforated sun shading. From simulations using SketchUp software, it was found that the visibility level of square and round graded perforated sun shading both provided a fairly good level of visibility.
