Abstract

Vernacular house façades have distinct visual characteristics as a reflection of the factors that influence vernacular architecture, one of which is how the locals perceive and interpret aesthetics. This study attempts to quantitatively examine the aesthetic qualities of the façades of two vernacular houses, namely Rumah Gadang from West Sumatra, western Indonesia, and Uma from Sumba Island, eastern Indonesia. Both have very different geographical conditions, cultural, and historical backgrounds. The fractal dimension analysis is used by breaking down the façade into 5 layers of architectural attribute; silhouette, main tripartite, structure, façade components, and material texture. Using the box-counting method, it is known which layer is the biggest contributor to the visual complexity of the façades. Based on the calculations, it is concluded that there are differences in the degree and proportion of visual complexity in the case of the two houses. The façade of Rumah Gadang has higher visual complexity than Uma. Material texture is the most dominant contributor to visual complexity of both houses. In Rumah Gadang, the façade components greatly contribute to visual complexity, while in Uma the silhouette has a big influence. This finding can be attributed to the way the homeowners place importance on the façade and the house in its respective social system, or even the development of civilization behind the two houses. It is also found that subjective-qualitative visual observation and philosophical approach do not always correspond with the result of mathematical calculation.

Abstract

The energy crisis and global warming are driving the importance of energy efficiency in building design. An ideal building not only prioritizes aesthetics and function, but also energy efficiency as well as comfort and safety for its occupants. In Indonesia, the Green Building Council Indonesia (GBCI) plays a role in promoting environmentally friendly and sustainable architectural practices. One popular method for energy efficiency is the use of eggcrate, which is a shading system in the form of lattices that reduces the intensity of sunlight, thereby lowering indoor temperatures and reducing energy use for cooling. The use of heat-reflective glass is also common in energy-efficient building design, because it reflects solar radiation and reduces incoming heat without sacrificing natural light. This reduces the workload of the air conditioning system, thereby increasing energy efficiency. According to Asih (2012), environmental control in buildings is greatly influenced by the use of glass and shading elements. Building façades, including glass areas, play an important role in energy conservation by reducing incoming heat conduction. In addition, glass also influences natural lighting and has positive psychological effects, while maintaining comfort and energy efficiency in buildings.
