Lighting control and next-generation light

2019 10 issue

As large-scale disaster and BCP measures, I come to often plan driving for the long time of the emergency generator.
As the large emergency generator uses fuel oil A as fuel, I install the fuel tank which I buried in the basements as driving measures for a long time. When capacity such as the fuel oil A stored to the fuel tank exceeds the designated amount of dangerous materials in the Fire Services Act, dangerous materials bank setting permission application is necessary. In addition, the dangerous materials handling place setting permission application is necessary when the fuel consumption of the emergency generator exceeds the designated amount of dangerous materials. The electric equipment person in charge rarely experiences the setting permission application of dangerous materials and will need great time for documents making as prior consultation and the application procedure with the fire department are complicated. Furthermore, about the inspection of dangerous materials about fuel tank of the undergrounding under the ground, there is much inspection before the completion inspection including the intermediate inspection of the structure body of the tank room, the in front of completion inspection inspection (I include an application) of the tank body and the acceptance inspection.
If by publishing features about the process control until an examination of documents making and completion accompanied with the setting of dangerous materials this time, is helped the electric equipment person in charge, I am happy.

　Electricity facilities, the power equipment is heart and muscle if they compare it to people, and it is brain and a nerve, and the yard information and communication, the low current facilities are the five senses such as eyes or the ear. Electricity facilities, the power equipment contributes to building value as strength of facilities. The communication facilities continue providing new service with high convenience by increase of the recent information and increase, low cost of the ability for information processing, and the technological change is remarkable. However, it increases for we industry to depend on a maker and the specialized construction company of the latter facilities and has been become the flight recorder. Therefore an emphasis is placed in wiring classification or the route between the apparatus about a case and the construction that a design condition is not arranged enough in the design, and accumulation of the knowledge seems to be lack for more information about a system.
I had you added the places that wanted the design and construction side to consider it in particular more such as makers with getting more specialized knowledge about the yard information and communication, low current facilities by this special feature and explain it.

In the times of the bubble, the future plans such as 100-story super high-rise buildings were announced by Japanese various construction companies. It might have done not come to come true, but these were very attractive for oneself.
In late years plans such as surpassing 1,000m are going in the foreign countries, and it is not 1,000m grade in Japan, but the plan of the skyscraper is progressing much now. The compound use that pursued a way of thinking and convenience as the wide area area as a point slightly different in these so far is it in a change in a way of thinking including making it it. In addition, the examples of the super high-rise seismic isolation increase from needs of BCP technically, too, and various things including the existing building dismantling technology come to be seen from consideration to surrounding environment.
With the appearance of these new needs, the E.E. will evolve more and more in future. I took up various superior techniques by a special feature, but there are many these techniques, and even this magazine is introduced into a current skyscraper. It may be, so to speak, said that the skyscraper is a trade fair of the state-of-the-art.
I want to introduce these introduced latest E.E. and E.E. whom introduction is expected of in future through a skyscraper.
