Enhancing residential energy efficiency enhancement: through the use of system dynamics

The objective of this paper is to attain a better understanding of factors affecting residential energy efficiency and propose macro policies to reduce energy consumption in the residential sector. It was performed using system dynamics methodology on a family of medium social class. Residential energy efficiency was considered as a system with five sub-models based on energy, economic, social, home appliance, and house efficiencies. Once finished with determining a causal loop diagram, dynamic models, and significant trends and validating and simulating the system, macro policies were presented both separately and together as a combined policy for system improvement. Policies included GDP improvement, the rise of energy prices, and enhancement of promotion programs. Further reviewed in the present study were relevant policies set forth by the International Energy Agency and four countries: USA, Germany, China, and Saudi Arabia. According to the results and reviews, improvement policies are coming to an end.
