Abstract

It is expected that in-home and out-of-home energy consumption behavior in a household might be correlated with each other, probably due to the existence of household budget constraints. Ownership and usage of energy-saving technologies for in-home appliances (or vehicles) might lead to the increase in out-of-home (or in-home) energy consumption. It is therefore necessary to jointly represent in-home and out-of-home energy consumption in the same modeling framework. With this consideration, we first build a new type of energy consumption model based on the Multiple Discrete–Continuous Extreme Value (MDCEV) modeling framework. Next, we conducted a questionnaire survey in Beijing in 2009 and successfully collected the information about households’ energy consumption, ownership/usage of in-home appliances and vehicles, and households’ and their members’ attributes from 1014 households. Throughout an empirical analysis, it is confirmed that the MDCEV model is effective to simultaneously describe the in-home and out-of-home energy consumption behavior. In addition, it is revealed that a set of household and personal attributes affect the ownership and usage of in-home appliances and vehicles. Furthermore, it is shown that the unobserved factors play a much more important role in explaining energy consumption behavior than the observed attributes of households and their members.

► Representing in-home and out-of-home energy consumption behavior jointly. ► MDCEV model is built to describe household energy consumption behavior. ► Log-linear competitive relationships are found among expenditures of end-uses. ► Model results provide some insights about the influence of varied observed factors. ► Unobserved factors are more important in explaining energy consumption behavior.
