Abstract

Simple rental Flats (Rusunawa) is the government's role in overcoming the need for housing, so that the quality of housing becomes more feasible. The feasibility can be seen from the thermal side of the flat so that the occupants of the flat are more comfortable living in it. This research simulates with software in low-rise apartment buildings so that they get a typology of effective and thermally comfortable flat-panel design. The typology can be a directive for architects in designing a flat which prioritizes thermal comfort for the occupants as well as a flat design that is quite effective and profitable for developers. The software used is Ecotect, Energy Plus, CFD and Dialux. With the simulation software, the double load corridor layout is more effective in terms of development costs and still has a good air exchange. While the orientation of the North-South building is better so that it can reduce the amount of openings from the direction of the coming sunlight.

Abstract

Many houses that exist on this earth. Therefore, it is necessary to have tactical and intelligent thinking in designing a home. Many things are rarely considered related to the effects of the design of building elements when related to the temperature or the energy produced. Existing background regarding efforts to reach a comfortable temperature can not only be solved in terms of mechanical systems, but the architectural approach can help and provide a comfortable effect for its inhabitants. This research was conducted to determine the level of thermal comfort or temperature in the room of a residential design that would be related to the size of energy consumption by applying several alternative designs or ceiling forms. This type of research is research using simulation methods through a computer model. The results showed the use of ceiling type Vaulted Ceiling was able to increase the Surface Inside Temperature value by 3 ° C when compared to the type of drop ceiling. The Mean Radiant Temperature value when using the ceiling vault type rises 0.6 ° C and on the acquisition of Operative, Temperature rises 0.3 ° C. The use of insulation material on the roof can significantly reduce Mean Radiant Temperature and Operative Temperature at 1.7 ° C at Mean Radiant Temperature and 0.8 ° C at Operative Temperature. Seeing the results of the simulation in this study, the recommended ceiling type is to use the drop ceiling type because it is quite capable of keeping the temperature in the room not too high so that thermal comfort can be achieved. However, if you want to apply a ceiling design with a model or type of drop ceiling, it is better to use additional insulation material so that the heat transmission temperature is not too high in the room.

Abstract

Glass Reflectance is the ability of the glass surface to reflect light when passing through the glass surface. All types of glass have this capability (Clear Glass, Tinted Glass, and Reflective Glass). With its ability, not all the light will be passed through the glass because the glass surface will reflect some of the light. The magnitude of reflection depends on the tilt angle of the glass against the light direction. It means if the glass is applied to the building façade and exposed to sunlight, not all sunlight and the heat forwarded into the building. To know the exact tilt angle of the glass when applied to the building, research on the effectiveness of light reflection by the tilt angle of the glass is necessary. This research uses a computer simulation method with hypothetical building objects. This research aims to test how effective the tilt angle of glass reflects the sunlight when applied as the building facade. The tilt angle tested in the simulation is a tilted and rotated glass. The tilt angle effect of the glass can be calculated using the building’s OTTV (Overall Thermal Transfer Value).Keywords: tilt angle glass, OTTV, simulation

Abstract

Buildings as absorber and heat reflectors can increase air temperature and as shaper formers can lower air temperature. However, both of these roles affect the extent of urban thermal environment, need to be studied through the form of canyon geometry creation of thermal comfort conditions outside space. The focus of this study is to examine how much the relationship between the vegetation and canyon geometry of urban thermal comfort in the humid tropics especially in Jakarta. This research used computer simulation method with hypothetic building object, to test how big influence of vegetation regulation on various canyon geometry to outdoor thermal comfort. Elements of canyon geometry that apply is aspect ratio and orientation. Because these two elements are the most influential elements in thermal comfort. The vegetation applied for this research is grass, greenroof extensive, intensive greenroof, greenwall and trees. Application of the vegetation in increasing thermal comfort is more effective than changing canyon geometry. However, the application of the vegetation will be more effective when applied in accordance with the canyon geometry.Keywords: canyon geometry, vegetation, outdoor termal comfort

Abstract

Latar belakang yang sudah ada mengenai upaya mencapai suhu yang nyaman ini tidak dapat hanya diselesaikan dari sisi sistem mekanikalnya, namun pendekatan arsitektural dari desain konfigurasi selubung bangunannya yang mampu membantu dan memberikan efek nyaman bagi penghuninya. Penelitian ini dilakukan dengan tujuan untuk mengetahui tingkat kenyamanan termal atau suhu di dalam ruangan sebuah desain rumah tinggal dengan menerapkan beberapa material dinding yang berbeda-beda sehingga didapatkan nilai perbandingan tingkat kenyamanan termal setiap material dinding yang diaplikasikan. Jenis penelitian ini adalah penelitian dengan menggunakan metode simulasi melalui model komputer (computer model). Berdasar hasil analisis sesuai hasil simulasi yang didapat, maka pemilihan material pada menggunakan batako, bata dan bata ringan secara karakteristik memiliki sifat bahan yang mirip. Hal ini dikarekan karakter “thermal properties”ketiga bahan ini tidak jauh beda. Berbeda dengan material kayu, berdasar hasil simulai untuk memperoleh Surface Inside Temperature, Mean Radiant Temperature dan Opertaive Temperature mendapat hasil suhu/temperatur paling tinggi.

Abstract

The increase in urbanization has an impact on indoor environmental quality and energy consumption in urban buildings in Indonesia, particularly in low-cost apartment buildings (Rusunawa). Despite providing affordable housing, Rusunawa faces challenges related to electricity consumption in achieving indoor comfort. The implementation of passive design elements such as balconies is expected to maximize natural ventilation indoors. This research aims to identify the influence of balcony configurations on the performance of natural ventilation in Rusunawa buildings in Indonesia, aiming to provide guidance in optimizing indoor comfort through natural ventilation. The method employed in this research is Computational Fluid Dynamics (CFD) simulation using Rhinoceros & Butterfly. The results of the study indicate that the width and depth configurations of balconies significantly enhance the Air Changes per Hour (ACH) and wind speed. A balcony width configuration of 40% yields an indoor air quality improvement of 18-26%, while a depth configuration of 20% results in a 9-10% enhancement
