“Suntube – New energy lighting | Tubular skylight system 3000 questions / Part 1 ”
Nowadays, new energy lighting (namely Tubular daylighting) has been gradually popularized in the market. Occasionally, you can see the light collector device of the tubular daylighting system on the road even more.
Lot of friends are interested in the tubular daylighting system, and have learned about the products from different channels, some of them sent me a lot of questions. So, today, I’m going to choose some of those questions and give you a simple answer.
why are most of the tubular daylighting systems used in factories, stations and other large projects? Is it not suitable for small projects?
Answer: First of all, the factory, the station, all called – space place.
As for space place, there is no clear definition. It mainly refers to the places with attributes of offices, factories, gymnasiums, underground garages, shopping malls, parks and other places that tend to public areas. The reason why the tubular daylighting system often appears in the space place, rather than into thousands of households, is not because the project is too small, in fact, it is also related to the nature of the tubular daylight.Let’s start with the characteristics of space place, such as gymnasium, shopping mall, underground garage, the use of light demand is relatively large.
For example, also only one car is parked in an underground parking, but the lights had to be on all day. This will lead to unnecessary energy waste, if the use of tubular daylighting system, can rely on outdoor sunlight during the day, so the electricity will be saved during the day. So it's not unsuitable a small project, it's based on the nature of the place.
Since it is so energy efficient, can the tubular daylighting system be installed in the house?
Answer: In fact, this is similar to the above problem, whether to install depends on the property of the house. Since most people spend at least 90% of their day in the office or outdoors, isn't it overkill to install a lighting system in your home? In addition, due to the requirements of installation, the installation of general purpose light tube requires the operation of trepanning and waterproof works.
In addition, due to the requirements of installation, the installation of general purpose light tube requires the operation of trepanning and waterproof works. If it is a residential building or a building with too high floors, it may not be suitable for implementation. Specific problems need to be analyzed. If you are interested, you can leave me a message or send me a private message, I will reply and provide a reasonable solution ASAP.
Although the tubular daylighting system saves electricity and money, but the installation needs cost also, is it really saving?
About this point, I do not want to say more, directly to the case (“SUNTUBE” tubular daylighting system as an example) :
Location: Chengdu City, China
Area: 40,000 sq.m.
The electricity consumption per unit area is 6w/sq.m.
Lighting time during daytime calculated as 10 hours.
Total electricity consumption of daytime is: 0.006 KW x 40,000 sq.m. x 10 hours=2,400 KW
Total electricity consumption of year is: 2,400 KW x 365 days = 876000 KW
The price of electricity in Chengdu is RMB0.8/KW/H, then
The daily cost of electricity is RMB0.8/KW x 2400 KW= RMB1,920.00
The year cost of electricity is RMB1,920.00 x 365 days = RMB700,800.00
The cost of “SUNTUBE” tubular daylighting system is RMB2,368,800.00
RMB2,368,800.00/ RMB700,800.00=3.5 years
Three and a half years time, can recover the cost, after then every year savings are profits, there are instances, there are data. Now, I think I need not say any more !
Well, that’s all for today! I will collate other questions for everyone to share and answer! Bye!
