Abstract

The need of residential space for low-income people has to be facilitated in urban spatial planning. Because of people will find affordable settlements in the suburbs so their daily mobility will cause congestion. In addition, the inadequate need for a place for low-income households will result in the proliferation of slums in the middle of the city. The goal of this research is to develop an optimal model in generating affordable high-rise residential design performance to improve the environmental quality and sustainability of urban spatial. The object study is a public housing as an affordable housing and formal settlement. When the cost of energy rises and availability decreasing, the need to provided energy-efficient design become more important. It is difficult to quantify and qualify the importance of values. This paper presents value-based decision to select energy system in an affordable high-rise residential building. Criteria for evaluating value are initial cost, life cycle cost, collaborative function, sustainable function, and integrative function. Model formulates, and its implementation based on application of satisficing option on multi criteria decision-making. Commencing at the design and planning stage, the technical, social, and economic sustainability of building energy needs to be considered.
