Abstract
Compact city emerged as one of the concepts that opposed the concept of urban sprawl. Its primary objective relied on the greater densification of spatial use under the term called mix land-use to reduce energy consumption on mobility. Our article intended to delve into a study which relates electricity to Compact city. The focus is to quantitatively analyze the interdependence between Compact city and electricity efficiencies. Simpang Lima central business district (CBD) in Semarang city constituted the field study. This article employs positivistic approach that consists of cross-analyzing GIS-Nearest Neighbor analysis dedicated for spatial buffering analysis and ETAP technique devoted to calculating energy losses within the CBD cluster. Our findings imply such a primary hypothesis that the distribution of the buildings on a cluster thatcovered by the electricity supply from central substation positively affected the distribution efficiencies. A group of commercial building with minimum distance of 129.49 m among them in a cluster of 1,424.6 Ha poses an ability to save more than 0, 293%(11.411/Kwh) compared to another cluster. Thus, this research is a preliminary discussion that aims at enriching Compact city discussion by bringing forth the electricity sector as a considerable aspect.
Highlights
The Compact city concept proposed a paradigm of mix-use spatial organization in which a greater energy efficiency could be attained in favor of cluster density formula (Ellis, Dantzig, & Saaty, 1975)
It can be concluded that the model the location of buildings in the commercial cluster become one of the variables that needs to be deeply considered in city planning process in favor of efficiency in distribution system electrical energy
Case study on this commercial district can answer the questions of the commercial buildings location which contribute to electricity efficiency and can probably the example of Compact cluster commercial
Summary
The Compact city concept proposed a paradigm of mix-use spatial organization in which a greater energy efficiency could be attained in favor of cluster density formula (Ellis, Dantzig, & Saaty, 1975). The implementation of compact city has clear connection with the government policy, the current of urbanization to the sector of transportation and energy consumption including its emissions. Energy efficiency within this type of city is able to be achieved by some innovation on urban planning rules by optimizing the city size and its characteristics (Lee & Lim, 2018). Socioeconomic factors covering its location and the standard of used households, are the potential and significant contributors on reducing the energy consumption (Mrowczynska&Sztubecka, 2020) It leads to a balance key of urban living and development for sustainable and lively city in a global urban form (Tappert& Drilling, 2018).
