بهینه سازی خانه های پایدار در مناطق شهری

The growth of time demands human to evolve needs. House as a primary needs is inseparable from the development of human life needs, especially in urban areas. The phenomenon of urban houses requires architects, developers, and even residents to be able to plan and collaborate in considering needs and limitations of land use. Humid tropical climate condition is a challenge for the planners or architects in creating indoor condition of the building that is eligible for dwelling. This paper aims to describe a simulation of interior arrangement to proving a design of efficient energy houses. The houses in urban areas are density houses with diverse environmental situations including density environmental housing and real estate. The identity of urban houses is characterized by inability to organize a dense interior space. Therefore, the requirements of comfortable and healthy dwelling are not fulfilled properly. The efforts to develop efficient energy, environmentally friendly and sustainable houses can be done through optimization approach of architectural design. The purpose of optimization is to find answers for possibilities of architectural design problems in order to obtain the best solution. The method of this research has been done by field observations to determine the pattern of spatial planning in several houses in Medan. In the process of model optimization, a possible improvement of existing dwelling model is designed through cyclical and analyzing planning, and alternative solutions that are sustainable and affect each other. The results of this analysis are expected to be a benchmark for local architects, researchers, and also residents in developing design optimizations, especially houses that have been built. This paper is a further research related to model developments of houses for urban community in Medan. Through an appropriate alternative interior arrangement, this research is expected to achieve the optimum design of houses based on the character of the urban environment without losing its identity as dwelling.
