Abstract

Utilization of natural light in an open building apartment is one of the several ways to save energy. Not only saving energy but it also sustains the healthy life of the occupants. This paper discusses the effect of layout alternatives mainly due to the potential changing arrangement of the bedrooms and the position of transparent window surfaces on daylighting performance i.e illuminance distribution and averages of illuminance. The Method used in this paper is an experimental method using Radiance 1.02 simulation as a tool. The changed layout in which is the bedroom spaces position concentrated on one window side of space with two separated transparent windows provides a good result with a percentage of area fulfills the standards equals to 29%

Abstract

Utilization of abundant sunlight in tropical climates as daylighting can help to save energy consumption in the flats building. Based on daylight conditions in tropics, there is a need for a dynamic shading to be applied in façade which can be transformed to respond to the environmental change. Folding shutter is a dynamic shading device which can be operated by using folding and rotation motion. This paper aims to discuss the impact of folding shutter on the daylight performance in the context of flats buildings in tropical climates. Simulation using Radiance was conducted to test the sub-variables of folding shutter, including the folding configurations and shutter’s rotation angles on different conditions in tropics. The results showed that folding configurations results in high increase of daylight intensity and should be applied moderately. Meanwhile the shutter’s slats can help to diffuse and reflecting incoming light to the deepest areas of room. A closed configuration with shutter’s angle of 0° and 45° performed the best to face the inconsistent cloud movement in partly cloudy sky. The integration of folding shutter and 60 cm overhang produced the most stable performance which can meet the visual comfort standard in the longest period in tropics.

Abstract

East Java art has a diversity of types and forms of performances. There are types of performances in the form of theatrical and ballet performances. This traditional art performance is intended to convey messages, advice, and past stories. This presentation is presented with various types of art so that between the types of theatrical or dance performances, each has a variety of needs for its stage and capacity. However, the lack of staging facilities is one of the problems that result in reduced artistic activities, so that some traditional arts in East Java are threatened with extinction. In this study, the purpose of this study is to look for patterns of flexibility in the auditorium to meet the needs of East Java art activities. The method used is the observation method. The observation was carried out by observing each type of East Java art activities to be accommodated, namely the type of traditional dance and theater. The selected arts are several art representatives who have the same type of performance. From the results of data analysis it can be concluded that the auditorium can at least adapt to 4 types of spatial configurations: arena, endstage, proscenium, and plaind stage.

Abstract

Modeling and simulation using computer software are very important in supporting various types of research based on data calculations. In the research process, accuracy is needed between the simulation results and the results of field measurements. Thus, there is no significant difference between the two results. This study aims to verify and validate the result of field measurements and simulation using the ARCHIPAK 5.1 software. The variables studied focus on indoor air temperature and humidity. This research takes a case study in the village of Ranupane which is located within the Bromo Tengger Semeru National Park. There are 4 housing buildings measured which consist of two types of houses using fireplaces and two types of houses without fireplaces. All of the four houses are afterward modeled using the ARCHIPAK 5.1 software to validate the data results. From the measurement results, the field measurement data show a higher hourly temperature profile compared to the results of the simulation of the base case model. Two striking differences are the type of house without a fireplace which is showing the difference in the average temperature of 1-2 K. While the type of house using fireplace shows the difference average temperature of 5,2-5,3 K. This occurs due to the internal heat gain input which the value is a slight difference between the result of field measurements and simulation of the base case model. This data verification and validation will be used as modeling optimal building configuration for housing in a humid tropical highland climate.
