Abstract

Persepsi adalah sebuah proses saat individu mengatur dan menginterpretasikan kesan-kesan yang ditangkap mereka dan memberikan makna/arti bagi lingkungan. Terdapat beberapa faktor yang mempengaruhi proses belajar (Chan, 1996) yaitu aspek visual, akustik, estetika dan lingkungan termal. Studi terhadap warna biru (blue) memberi efek menenangkan (soothing effect) didapati pada orang–orang yang sedang melihat badan air yang besar atau langit terbuka, sementara oranye (orange) memberikan rangsangan (Kopacz, 2004). Pada percobaan ini, dilakukan intervensi warna biru dan oranye yang diterapkan hanya seluas 12 m2 di bagian depan ruangan dengan produk Nippon Paint. Jenis cat yang dipilih ialah Biru (Arctic Blue) dan Oranye (Sun Fresh), dan lampu Philips Cool White. Dari riset, mahasiswa pada saat mengerjakan psikotes tidak terlalu merasa dampak dari dinding di bagian depan ruangan. Kemungkinan hal ini, disebabkan karena mahasiswa hanya sesekali melihat ke depan selama tes. Disarankan warna biru dan oranye ini dapat diterapkan pada bagian langit–langit serta meja agar lebih mempengaruhi (biru terhadap ketenangan dan oranye terhadap semangat). Kata kunci: warna dinding, menenangkan, menyemangati

Abstract

Sumber daya alam yang semakin menipis menyadarkan akan pentingnya mencari alternatif lain untuk menghasilkan energi terbarukan. Kemunculan bangunan-bangunan bertingkat yang unik di Indonesia, seperti memiliki kemiringan pada fasad, memiliki potensi lebih besar untuk menghasilkan energi terbarukan melalui energi angin. Namun  kemiringan yang ada membuat wind turbine vertikal sulit diterapkan dengan mengikuti kemiringan yang ada. Poros wind turbine vertikal diletakan menjadi sejajar dengan permukaan tanah guna mengikuti kemiringan fasad yang membuatnya berputar secara aksial dan radial. Penelitian ini mengkaji 6 (enam) model yang berfokus melihat pengaruh modifikasi bentuk serta rasio D:H terhadap kemampuannya mengolah angin secara aksial (Cp) dan kecepatan rotasi minimum yang dibutuhkan (TSR). Hasil dari penelitian ini menunjukan bahwa wind turbine aksial tanpa modifikasi bentuk dengan rasio D/H 1:2 lebih baik untuk diterapkan pada fasad miring.

Abstract

Most buildings have spaces far from the windows that require artificial lighting for illumination throughout the day. In fact, artificial lighting contributes to the second highest electrical energy consumption, especially in educational institutions that require more lighting. One of the appropriate solutions to illuminate areas far from windows is using a fiber optic daylighting system. FOD is used to distribute sunlight into the spaces away from the window. This research tested the lighting levels produced by alternative collector and diffuser models of FOD systems to meet the lighting level standards (lux) in discussion room P. 06. 05. Petra Christian University. This research uses experimental methods under actual weather exposure and simulation with DIALux software. Simulation results show that the room requires 6 collectors and 2 diffusers, arranged centrally and symmetrically. It produces 365 lux and a uniformity ratio of 0.59, which meets the standard. The lighting level data used was at 10:30 AM during partially cloudy conditions.

Abstract

The use of large glass facades in buildings without external shading devices leads to a high daylight level, uneven daylight distribution, and glare. A perforated screen facade (PSF) is one of the shading systems that can provide daylight and view and prevent direct solar radiation into a building. More research is needed about the daylight performance of PSF in integration with daylighting systems in the tropics. A combination of PSF and light shelf (LS), a daylighting system that can redirect daylight to the ceiling and enhance daylight distribution, is proposed to improve daylight levels and reduce glare. The research aims to evaluate the daylight performance of PSF and LS in the tropics. The research method is experimental with simulation utilizing IES-VE Radiance IES. Average Daylight Factor (DFavg), Useful Daylight Illuminance (UDI), and Daylight Glare Probability (DGP) of a room with a side window were compared with a room with PSF and LS. The results showed that implementing PSF and LS improved daylight performance by lowering the DFavg by 55%, increasing the UDI, and reducing the DGP.

Abstract

The increasing rate of urbanization leads to more unmanaged waste, currently at 33.08% of 18 million tons per year.  This research uses recycled cans as architectural elements to address the acoustic comfort issues in coworking spaces. Some of these studies have also recommended the addition of sound masking elements such as natural sounds, music, and others to enhance workers' productivity. Furthermore, earlier research has experimented with processing waste plastic materials into acoustic elements based on sound absorption theory. The aim of this research is to conduct experiments by using recycled waste cans as an architectural element that can function as sound masking, providing an acoustically comfortable sound range that supports users' well-being. Results show that recycled partitions placed between workers produced a sound intensity level of 57.6 dBA, which is still 7.6 dBA above the comfort threshold.

Abstract

A deep-plan office building design limits daylight access on the workspace distant from the side window. Horizontal Light Pipe (HLP) is one of the light transport systems that can deliver daylight to these areas. The research aim was to explain and evaluate the effect of HLP’s opening distribution area on daylight performance at deep plan-private office space. The research method was experimental with simulation as a tool. Daylight level and distribution of the base case, HLP with an opening distribution area of 6.6 m2 were compared with the case, HLP with an opening distribution area of 3.41 m2. The results showed that both cases distributed daylight uniformly. A 50% reduction of HLP’s opening distribution area, from 6.6 m2 to 3.41 m2 improved the average Daylight Factor as big as 6.42%. HLP with a smaller opening distribution area can be applied as the main source of daylight on deep-plan office spaces

Abstract

Horizontal light pipe (HLP) is a sustainable strategy for improving daylighting quality in buildings. The reflector is one of the HLP elements that collect and direct the incoming light in the pipe. Several reflector studies of HLP systems have been carried out in the last three decades under specific sunlight conditions at certain altitudes and azimuths or static conditions. This study proposes a dynamic reflector model in response to the movement of the sun angle. This study aimed to examine the impact of the dynamic reflector tilt angle on improving the quality of light by adapting the sun angle. The method used is an experimental simulation using IESVE software. This research is located in Surabaya, with a tropics climate. The results showed that modifying the reflector to be dynamic could increase the illuminance levels up to 29.9%, daylight factor values ​​up to 29.2%, and uniformity ratio values ​​up to 33.3%.

Abstract

Noise from the road exceeding 40 dB disturbs the room atmosphere and quality of rest in an apartment. The aim of this research will utilize the wind to swing the kinetic facade to create background noise that supports the user's well-being. The aim of this research is to invent a kinetic façade system that supports the apartment user's well-being. To achieve this, the research utilizes wind to blow kinetic facades to produce background noise which also reduces glare from sunlight thereby improving well-being. Experiments were carried out by comparing the results of measuring frequencies of bamboo musical instruments with solfeggio frequencies. The bamboo musical instruments analyzed included 18 angklungs, 3 windchimes and 21 variations of bamboo models. The frequencies obtained by the final model are close to that of solfeggio frequencies, namely 432Hz, 639Hz, 747Hz and 852 Hz. This can reduce Daylight Glare Probability (DGP) by 13.36%, 9.69%, and 5.01%.

Abstract

This paper explores the effectiveness of daylighting strategies in tropical vertical residential buildings, focusing on enhancing daylight performance to improve the physical and mental well-being of the dwellers. With more time spent indoors post-pandemic, optimizing daylight access is essential. A systematic review was conducted using databases such as Science Direct, IOP Science, and Research Gate, resulting in six studies that met the criteria of daylighting, vertical residential, and tropical context. These studies were analyzed to identify key strategies side lighting, atriums, and shading devices evaluated through metrics like Daylight Factor (DF), Spatial Daylight Autonomy (sDA), and glare indexes. Findings show that side lighting is the most common strategy, enhanced by innovations such as light shelves and adjustable shading. This approach improved Target Daylight Illuminance (TDI) by up to 300%, increased Illuminance Uniformity Ratio (IUR) by 180%, and reduced over-illumination by 32–86%. Atriums, though less frequent, showed potential in deeper layouts, increasing indoor illuminance by 0.9–19.2% and reducing corridor over lighting by 41–57.1%. Effectiveness varies by building type and climate, reinforcing the need for context-specific design. The main contribution of this paper lies in synthesizing quantitative evidence into actionable, climate-responsive design insights, providing architects with a concise reference for creating healthier and more sustainable tropical residential environments.
