Imagine such a scene: walking into a room, the sensor in the room can automatically arrange reasonable lighting and temperature control according to the number of people in the room and sunshine; the usage of each room can be directly checked through the mobile phone, looking for meeting room changes It's no longer difficult; people in the building can even manipulate nearby lights and air conditioners, while building managers can control the lights in every corner in real time.
Such a scenario is not illusory. With intelligent building technology, buildings can become “smart†and save a lot of energy – energy savings for buildings with tens of thousands of square meters and can accommodate thousands of people. Extremely important – on the one hand, the benefits of lower energy consumption to the environment are self-evident, and companies are happy to use it as an example of a positive image; on the other hand, even if the economic account is calculated, a building is consumed every year. The value of electricity on lighting can reach millions of dollars. Systematic energy conservation at the building level is clearly different from the “turning off the lights†of ordinary households – for example, through a series of intelligent energy-saving measures, the 66,000-square-meter Microsoft Shanghai headquarters can save $660,000 in water and electricity costs each year.
One of the biggest bottlenecks hindering the development of smart buildings is the high cost—any control of single-turn lighting means more sophisticated control systems, and the placement of sensors with network transmission in each room can make building costs extremely high.
The new office building in Deloitte, Amsterdam, the capital of the Netherlands, is an "smart" building as described above. The building, which was completed in early 2014, was awarded the “Best Design†certification of the British BREEAM Green Building Standard. Compared with other intelligent buildings, the Deloitte Building has a significant reduction in construction costs because the “wisdom†of the Deloitte Building comes from a smart light bulb – in addition to lighting, the interior of the luminaire is equipped with a variety of sensors that sense the room. The temperature, sunshine, and even the number of people in the room and activities. This allows the building manager to adjust the temperature and lighting according to the situation of each room to save energy.
Philips, which produces such lamps, is the most creative player in the lighting field. Previously, they developed a “HUE†lighting system suitable for home use. Home users can use the mobile phone program and wireless network to send commands to the home bulb to adjust the brightness and color. In the Deloitte building, every light can also be connected to the data network. Eric Rondolat, global CEO of Philips Lighting, believes that simply using the Internet for lighting is a thing of the past. “By integrating intelligence into LED lighting, we can create a digital lighting point that interconnects space, occasions and people.â€
Secret cable <br> <br> Deloitte shiny buildings is that it is not connected using illumination light to the power supply line, but are connected through the network cable. The network cable that can be seen everywhere can also carry power. This power supply method called "Power over Ethernet (POE)" can provide power for devices such as IP phones and network cameras.
But the power that Ethernet can provide is quite limited. For a long time, the power supply of the POE cannot exceed 30 watts. For traditional lighting, 30 watts is obviously not enough. But the rise of LED lighting makes this possible. Although the cost is higher than traditional lighting technology, LED is rapidly becoming the new favorite of the lighting market.
Compared with existing lighting technologies, the use of LED lighting can reduce energy consumption by more than 70%, which means that low-power POE can also supply LED lamps. “We don’t use Ethernet to generate electricity, but we use standard technology for transmitting sound over IP phones. With innovative use, today’s lighting efficiency is high, and the power needs can be met with a simple line.†Philips Professional Lighting Solutions Introduced by program CEO Amelia Huntington.
Hong Anli said that in the first quarter of this year, the LED business revenue ratio has reached 33% of the entire business, and it is expected that this number will reach 50% in 2015. The Philips Lighting Division spends 5% of its revenue on R&D investment, most of which has already been invested in smart lighting.
Being able to connect the luminaire directly with the network cable can undoubtedly reduce a large amount of cost - the cost of arranging the lighting power supply line can be omitted, and the lighting circuit is directly integrated with the IT system of the building. In the Deloitte building, wiring costs are saved by 50% in this way.
For a 40,000 square meter building that can accommodate up to 1,800 people, this means that the installation process is more convenient, and the direct installation on the network cable allows the light fixture to immediately have a separate IP address - each lamp is quite On a computer and directly connected to the network. “In this way, the luminaire becomes an 'Internet of Everything' device, connected to the building's data control system. Each lamp can be independently identified, positioned, and monitored and manipulated in real time.†Philips Lighting Greater China Advanced Marketing Director Yu Yongtao said this.
This idea also faces security issues. An easy question is whether there is a danger of being hacked when the lighting is directly connected to the building's IT system.
Yu Yongtao said, "The lighting system and other IT systems are isolated by virtual LAN. Even if someone can enter the IT system, they can't directly control the lighting system. At the same time, the Ethernet-powered lighting is running inside the company's firewall. The system will not access the Internet."
Hong Anli even believes that Ethernet-powered lighting systems are more secure than traditional systems. On the one hand, the use of standard cables, the reliability of maintenance and operation is higher than the traditional solution; on the other hand, compared with the traditional central lighting control system, the power-saving lighting uses a semi-distributed architecture, "router and The luminaire does not need to bring all the information together in one place, so the architecture is more secure."
Light and sensing <br> <br> while lighting system linked into the network, Amelia Huntington with her hands researchers are also aware that, why not integrate various types of sensors required for intelligent buildings to lamps What about it?
“Every corner of the building has lights, and there are sensors in places where there are lights. At the same time, because the lights are directly connected to the network, the data provided by the sensors can be transmitted back to the control center through the network in real time.†Yu Yongtao said, this practice It also saves on wiring and operating costs, and the sensing system covering the entire building can be realized at a lower cost. The data shows that heating, ventilation, air conditioning and lighting systems consume 70% of the energy of commercial buildings, while building equipment control systems can increase energy efficiency by about 30%.
Erik Ubels, chief information officer at Deloitte Holland, said: "By installing multiple sensors in the lighting unit, we can control the cooling, heating and air flow inside the building. In addition, we can Have a good understanding of the use of the building."
Due to the characteristics of Deloitte itself, not all of its employees follow the nine-to-five working hours, and the building also needs to undertake a large number of customer interviews, meetings and other work. This makes it difficult to manage the use of each room inside the building. Which meeting room was occupied? Which office needs cleaning? Which offices are not coming to work today?
These details can affect the brightness of the switch, the brightness of the light, and even the frequency of cleaning. “The general practice is that after the cleaners come, they will spend five to ten minutes in each room according to the regular cleaning process, or clean according to the contract. But if a room is all day long In use, there are people who have lunch in it, and only two people in the other room use it for 2 hours, then the cleaning of the room should be treated differently," Ubers said.
Don't underestimate the cost of these seemingly unobtrusive. In fact, statistics show that for office buildings, the cost of cleaning, meals, waste disposal, etc. is 4 to 6 times the cost of energy. It is better to be able to count how many people and distributions in the building. Arrange the corresponding work to save resources.
Big Data <br> <br> future as HONG ceremony said, "there will be a lot of professional lighting data generated, how the data into the cloud, the ability to communicate using the cloud big data analyzes it, and applied in the field of lighting control Is a problem worthy of attention."
The strategic cooperation memorandum of understanding signed between Philips China and Alibaba at the end of May this year is a clear signal that Philips hopes to provide support in the field of big data through Alibaba. Liang Hanfeng, president of Philips Lighting Division Greater China, said: "By cooperation with Alibaba, we hope to analyze big data and use or mine more data based on analysis, and convert through insight after big data analysis. This is a value. "This memorandum of understanding has not yet made substantial progress, but Liang Hanfeng revealed that the first step of cooperation will begin with consumer data analysis and gradually shift to professional lighting.
In a supermarket in Düsseldorf, Germany, the retail lighting system developed by Philips, in addition to providing appropriate and controllable lighting for each part of the supermarket, has also become a viable option for indoor navigation. According to Huntington, after the consumer installs the app on the mobile phone, the smartphone's camera is pointed at the light in the supermarket, and the light can send a code to the smart phone to help the phone to accurately locate. “With the app, consumers can know where they are and receive information about their products nearby. You can even enter a shopping list and the APP will plan the best route for you.†Yu Yongtao said.
This indoor positioning solution was also used in the Deloitte building. Through the same mechanism, employees can let the building control system lock their precise position, and the user can adjust the intensity of the ambient light and air conditioner through the APP.
And Philips' ambitions don't stop there. At the end of March this year, Philips announced cooperation with power and automation technology supplier ABB. This collaboration means that Philips' connected lighting systems will seamlessly interface with ABB's automation software, including controls for lighting, curtains, access control, heating, ventilation and air conditioning systems. For example, if a hotel needs to integrate several separate rooms into one large meeting room, the lighting scene can be changed with a single click. For shopping centers, if you need to divide a unit into several small units, the central manager can easily reset the entrance, heating, ventilation, air conditioning and lighting systems.
