BIOCLIMATIC ARCHITECTURE AS A DESIGN APPROACH WITH A MIDDLE APARTMENT IN SURABAYA AS A CASE STUDY
Full text linkBioclimatic architecture as a design approach takes an advantage climate parameters to answer the problems of environment and energy. This approach is applied to optimize the quality of architectural design through the comfort and health of their environment. It was developed by simulating the design in the case of a middle apartment in Surabaya. To achieve its design goals is simulated: 1) transforming mass-form, 2) setting housing-unit plan, 3) making housing-unit facade, and 4) organizing overall lay-out. Simulation of this design is using several alternative designs to obtain an optimal design. Bioclimatic architecture is successfully implemented if it can optimize the potential of the existing climate. Bioclimatic quality is achieved when a middle apartment is designed to optimize penetration of natural light, cooling and air exchange building mass as well as minimize the acquisition of direct solar radiation. Bioclimatic architecture approach requires consideration of such architectural contexts: urban, economic and social aspects, because the technical nature
SMART GENERATIVE ALGORITHM (SMART GEN-A): 2D ARCHITECTURAL PHOTO CONVERTER TO BE THE DIGITAL 3D OBJECT
Full text linkAll objects have various shapes and dimensions. When the three dimensional objects were captured by camera, the output will be two dimensional images although were captured from different angles, this will lead to some misperceptions for observer especially the one never seen the images before. To overcome these misperceptions, it was required a program which is capable of converting a two dimensional image in a digital three dimensional objects. However, conversion process takes a long time without standard measure of real objects to virtual especially for objects with different basic form. The standard is the parametric box with parametric coordinate points to allow creating virtual objects with nearly the exact size of the original. The research uses Rhinoceros 4.0 and Grasshopper to generate the algorithm. The algorithm is designed based on the basic form of object (circle, triangle and square) by using the hierarchy logic of the water gallon. The result is the Smart Generative Algorithm (Smart Gen-A) which can re-create the 2D image into digital 3D and even give the nearly unlimited possible shape for architectural reconstruction
G-FEET STICKY HOUSE: THE STRONG AND QUAKERESISTANT HOUSING FOR POST EARTH QUAKE SOLUTION
Full text linkEarthquake is a natural phenomenon occurs in Indonesia. Naturally, earthquake does not kill people, but buildings do. People were killed by the fallen debris of building parts when earthquake occurred. The key to create an entire building lies on the joint system which is why most of building failures occurred on the joint system. Prawiro et all (2010) stated that G-Feet Structural Joint System is the future alternative reversible structural joint system designed based on gecko’s feet concept. The research by Andari et all (2011) found that the joint system was optimum in shear stresses which were mostly created by lateral forces of earthquake. The idea was more lateral forces would lead the joint system to become stickier. Sticky brushes refer to the ability of joint system to easily stick and become strong enough receiving 10 tons/m² load. This can be happened due to the geometry of sticky brushes which are becoming the locking system of the joint system. Therefore, G-Feet Sticky house is supposed to be a new concept of post earthquake houses for the victims. Material selection and 3D computer modelling were used for the final design of G-Feet Sticky Houses to be safely and easily to install. The design is supposed to be useful and helpful especially for the victims as temporary houses which can be modified as the permanent one. The big wall panels are designed for faster construction processwhile the joint system combines the ability of sticky brushes and the geometry of wall panel edge detail
EVALUATION OF INDOOR COMFORT AND BUILDING ENERGY PERFORMANCE OF STUDENTS RESIDENCE AT SAM RATULANGI UNIVERSITY IN MANADO, INDONESIA
Full text linkThere is no information that the student residence of Sam Ratulangi University is especially designed energy-efficient. It is necessary to evaluate the design from the view point of energy conservation associated with the fulfillment of indoor comfort. Through this study, observation, measurements and calculations of comfort, ventilation, heat and lighting were performed to get information if the design follows the Indonesia standards on comfort and energy conservation. Questionnaires to residents were also conducted to obtain compliance response to the comfort standard. Air temperature, wind speed, humidity and lighting were measured, simultaneously with a questionnaire regarding the level of comfort to occupants. Scale of the thermal comfort in the room refers to the ISO-7748. The use of electronic devices such as computers, fan, TV, etc. are also recorded to determine the level of electrical energy consumption. The results generally indicate that there are differences in comfort perception between the level based on references and by the respondents. Overall, the design is not a type of energy efficient building even OTTV of the building envelope is 49.79 W/m2. Energy consumption of the rooms are in range of34 kWh/m2/year to 157 kWh/m2/year.
SUSTAINABLE, ECOLOGIC AND GREEN ARCHITECTURE, TOWARDS INDONESIA SUSTAINABLE FUTURE
No full textThe objectives, “Why Are We Becoming Green”? The first idea to greening the structural architecture building just recognized recently, why? Because there was a belief that the environmental enhancement efforts to combat its degraded environmental quality including “the green (building) is not our business, it is government business”. It is actually everybody business. In urban area, eighty percent of our activities are inside the building; at home, office, school, factory, hotel, gym, etc, only a small amount of the time spent outside the building, on the road or inside the car. Green is at the moment, a popular term in our daily life; a lot of companies and businesses claimed that they are green, by merely applying certain features in their properties. A lot of new property development claim that their development is “green”. Some Indonesian architects and engineers have been designing and applying the green principles in the design and achieve what supposed to be a green building standard. It is not merely a trend, it has to be a lifestyle change, the demand of the consumer of a “green” living environment meets the planet current conditions, climate change and degrading environmental conditions. The theoretical frame work is that it is timely and important to establish a Green Building Council. “Green” has become the shorthand term for the concept of sustainable development as applied to the building industry. Green buildings, including the appropriate site development as a sound landscape planning and design also known as high performance “buildings” in terms of i.e. materials efficient used, wise settings in the case of socio-economy-physical environment development as a whole, are intended to be environmentally responsible, economically profitable, and healthy places to live and work. If not, then all of us will be suffer caused by the negative environmental impacts. As human beings as part of the planet biological creature, we should be part and follow the natural law of the globe natural process
TOWARDS ECO-URBAN SETTLEMENT: LEARNING FROM LOW-MID HOUSING VACANCY PHENOMENA IN THE CITY OF BEKASI
Full text linkEco-urban settlement is integrated concept of environment sustainability and urban settlement. As a dominant element in urban area, housing plays a critical role in producing sustainable settlement as it significantly influences physical environmental quality as well as social and economic productivity. The provision of decent housing therefore become strategic approach to produce such a strong urban community that will functions as an importance factor in enhancing urban sustainability. However, it is not a simple idea as housing decency is a conditional aspect with regard to heterogeneous needs and housing characteristics. In dealing with urban housing insufficiency, the Government of Indonesia has introduced a housing ownership program for low to mid income people. This strategy in some extent offers social, economic and environmental benefits and forms strong neighbourhood and communities that will be valuable capital for enhancing urban sustainability. However, this strategy does not present its incentives as it puts its orientation on quantitative measure rather than social aspect. This paper exposes the condition of low-mid income housing policy implementation in relation to eco-urban settlement process. The fact that about 40.2% of abandoned low-mid income houses in the municipality of Bekasi, in West Java, Indonesia indicates the importance of social dimension in dealing with sustainable urban settlement objectives. Regression analysis of data both at macro and micro levels discloses the correlation between low mid people needs and the abandonment. The result shows the importance of integrating social dimension into the housing provision strategy for effectively achievingeco-urban settlement goal
