Advertising for all-electric apartments has increased through a growing number of flyers and billboards. In the case of newly constructed high-rise apartments, all-electric power is being adopted as standard equipment. All-electric power in detached homes is being promoted as a component of airtight, highly insulated house design that results in energy savings.
In 2004, according to a survey by Matsushita, the number of new all-electric homes reached 270,000, making up more than 16 percent of newly constructed homes, for two-digit growth over the previous year. In addition, an increasing number of existing homes are being converted to all-electric power. More than 60,000 were converted in 2004, for growth of more than 30 percent over the previous year and surpassing the growth-rate of newly constructed all-electric homes.
It is estimated that conversion of existing homes to all-electric systems will continue increasing and the number of existing home conversions will equal that of new all-electric homes within 4 years to 5 years.
According to a survey carried out by the Tokyo Electric Power Company, more than 90 percent of respondents gave all-electric homes high ratings for safety, less moisture condensation and, most importantly, lower heating and lighting costs.
The increased popularity of all-electric homes has been supported by factors such as lower-interest loans, discounted fire insurance rates and utility rebates.
