It should be complicated "housing equipment" that should be comfortable, but inconvenience

It seems that there are cases where various latest equipment is introduced, but there are cases where there are problems such as unknown or not being used (photo: Kuppa_rock / Istock) See the image of this article (◯ sheet).

The technologies and ideas used for products and services in the world are evolving on a daily basis.The same goes for the field of housing.However, the introduction of various devices only to life is not used in homes, and in some cases, in trouble.[Photo] Image of a dedicated monitor of HEMS, for example, a smart house, an advanced house equipped with solar power.It was spread since 2011, when the Great East Japan Earthquake occurred, and the increase in interest in energy issues due to the nuclear accident has led to its popularity.

Typical examples of energy -saving housing are increased, and nowadays, such as home storage batteries and energy -fars, have appeared.One of the core technology is HEMS (home energy management system).This "visualizes" the supply and demand status of energy in the home.The supply and demand status is almost in real time, so it helps to save energy and save power.In addition to dedicated monitors, PCs, mobile phones, and tablet terminals can be checked for energy status.

■ HEMS, which is not used very much, but some people who have introduced HEMS due to increased energy -saving awareness seem to do not feel the benefits.For example, Mr. A, who has been in an energy -saving housing that has installed solar power since 2014, talks about HEMS as follows."When I started living, it was very interesting to see how much solar power generation was generating and how much I could save compared to the electricity price with my home, but now I can't see it at all.I have gone "

I was tired of saving energy while living for a long time.The most important thing in your home is that you are comfortable.I'm not living to save energy.Therefore, HEMS gradually became unused facilities.Increasing the number of coordinates may cause problems.For example, home storage batteries can be used in the event of a power outage, providing security when a disaster occurs, but may not be able to be used smoothly.This is because there are some that need to operate the storage battery manually when a power outage occurs.If only young children and the elderly are at home, you may not be able to use storage batteries.
