Abstract

This paper introduces the application of OpenStudio – a visual software co-operating multiple-interaction analysis between architectural model design on Google SketchUp and energy simulation on EnergyPlus to apply home energy management systems in residential houses. Compared with actual observation, OpenStudio can predict the energy data exactly at 86% or more and suggest optimal solutions to reduce energy consumption on space heating in winter, which is equal to 16% of total demand energy in the case study. Simulation results indicated that the schedule setting that follows inhabitant’s habit can save 24% comparing to 24-hours usage, meanwhile adapting real occupancy on this schedule may reduce 29 – 38% energy consumption. If we can decrease thermal comfort
from 24o C to 22o C, the space heating electricity is supposed to be saved up to 44%. The research area is based in Higashida Smart Community, Japan, which emphasizes the crucial role of a detailed investigation on inhabitant’s occupancy to detect energy waste at home and provide suitable sensor equipment for suggesting residential energy- saving decisions based on the application of energy-analysis software in general and OpenStudio’s simulation particularly.
