Abstract

This study aims to determine the urban resident’s preferences and evaluation structure towards living environment in Indonesia using the Evaluation Grid Method (EGM) and analyse their associations with household energy consumption. The EGM clarifies a respondent’s evaluation structure using a hierarchical diagram. A nationwide survey (n=1355) was conducted in several Indonesian cities. Data on gas and electricity consumption were also investigated as energy consumption data. We analyzed the preferences and evaluation structure across several groups with various household energy consumptions at different scales, including behavior, interior, building and neighbourhood. The results revealed that there were several differences in preferences and sense of values among households with various levels of energy consumption. The households with high-energy consumption favoured “socialization with family, and “living in clean environment,” amongst others. For their preference in building scale, some of respondent tend to not live in an apartment. Meanwhile, those with low- and medium-energy consumption preferred similar types of buildings. Despite this, the households with medium-energy consumption ranked “building quality” and “eco-friendly environment” as their priorities.
