Relationship between Arrangements of Houses with Air-conditioners and Usage of Electric Power

Abstract

Usually, outside air temperature of a house increases when we use air-conditioners because of exhaust heat from the outdoor units. Consequently, electrical consumption of the area increases because many people turn on the air-conditioner. Influence of this phenomenon depends on distances among each house and arrangement of the houses. Obviously, distance between each house becomes further, effect of exhaust heat gets weaker, but the distance cannot be extended easily in urban areas because of limited space. Thus, relationship between arrangement of houses with air-conditioners and electrical consumption in a target area is investigated. A house with an air-conditioner and an outdoor unit is represented as a mathematical model, and multi-agent simulations have been conducted with the model. Effective arrangements of houses and ineffective arrangements of houses have been found by using random search method, and the arrangements have been compared. It has become clear that electrical consumption decreases when houses with low preset temperature get closer with each other in built-up areas.
