ANALYSIS OF HEMS DATA IN A DETACHED HOUSE (PART 1): ENERGY CONSUMPTION BY CONSTRUCTION YEAR AND APPLIANCES
We have been studying energy consumption using data from Home Energy Management System since 2011. In this paper HEMS data of about 50,000 houses were collected and analyzed. We clarified the composition of HEMS data. It turns out that the energy consumption is decreasing as the buildings are newer....

description | We have been studying energy consumption using data from Home Energy Management System since 2011. In this paper HEMS data of about 50,000 houses were collected and analyzed. We clarified the composition of HEMS data. It turns out that the energy consumption is decreasing as the buildings are newer. we further analyze energy consumption by appliances. The purpose is to promote energy saving of new houses and existing houses Energy consumption ratio in the household sector has not stopped the increase trend of 26.5% in 1990 to 30.4% in 2016. The data acquired by HEMS includes total energy consumption, usage, equipment, power generation, storage battery charge / discharge, electric vehicle energy, construction site, construction year, floor area, and family composition. The average floor area is 121 square meters. This is almost equal to the average floor area of Japanese houses. The total energy consumption was analyzed. Compared to 2011, the reduction is about 30% in 2017. A comparison was made between a couple, a single household, and two households. It turns out that couples have the greatest reduction rate. Monthly analysis was also conducted. It turned out that the reduction rate is particularly large in spring and autumn. An analysis of hot water supply energy was also conducted. The adoption rate of heat pump water heaters is improving year by year. Nearly 100% since 2012. Energy consumption has also been reduced by about 30%. The reduction in winter is particularly large. The reason is the high efficiency and high functionality of the equipment. An analysis of energy consumption for air conditioning was conducted. The adoption rate of air conditioning throughout the building has been increasing since 2011. Energy consumption is increasing. The reason is that the entire building is operated continuously with air conditioning. We analyzed consumer electronics, ventilation, and lighting energy consumption. Since 2011, type 1 ventilation has a 20% greater consumption than type 3 ventilation. But in 2017 it is equivalent. This is thought to be due to an improvement in the efficiency of a type of ventilation. It was found that consumption was reduced by about 50%. The reason is presumed to be high efficiency of home appliances and LED lighting, This will need to be clarified in future research. |
