Sinclari: We know that Lumenergi offers a next-generation integrated lighting management solution that can help achieve a smarter energy network. Can you tell us about the role of integrated lighting management in the future of efficient energy?
D'Amour: Thanks Ken, I am happy to discuss this issue. I believe that you will agree that creating a smarter energy network is a very important task for our country. In October, the Obama administration announced that they would use the “SmartGrid Investment Grant†to award $3.4 billion for the modernization of the grid, which would add $4.7 billion through private funding. At the same time, the federal government passed a bill to collect real-time electricity prices, so unless users do not want to respond to these higher dynamic electricity prices, they will definitely need to start monitoring how they consume electricity.
Lighting energy consumption is the largest part of the building's energy consumption, control energy consumption, accounting for almost 30% of commercial building energy consumption. This will greatly promote the widespread acceptance of intelligent lighting systems. Although smart lighting is an important part of smart buildings, and in essence it complements the development of smarter energy networks, only about 3% of lighting is currently intelligently controlled.
Our goal is to create smart buildings that are energy efficient, responsive, and adaptable to virtually any change in the power market environment. Our systems are cheap, efficient, easy to use and offer a very high return on investment. We believe that our solutions and other similar solutions are key components of the smart grid.
Sinclari: Very attractive! I agree with your judgment. So, can you introduce the products, solutions and unique features of Lumenergi?
D'Amour: Ok. We offer our customers a fully integrated lighting solution with the concept of the next generation of intelligent lighting systems. Our systems help users achieve smart buildings that are energy efficient and responsive, by installing lighting systems that can be monitored, fed back and controlled in real time. Based on the energy consumption data, the building manager can find out when the lighting is not working properly and can control the lighting directly on the computer screen. Our patented product, the Smart Dimmable Ballast, makes it easy to replace traditional “dumb†ballasts in lighting system retrofits or in new construction.
Our smart ballasts are powered by our advanced lighting management control system. The system provides building managers and residents with more advanced control and management functions that enable them to save money by intelligently using lighting and reducing maintenance costs. The system will send you a notification email when your lights burn out, when the ballast fails, and when the room needs to be replaced. At the same time, it can help create a more interesting, more personalized and aesthetically pleasing user experience.
The system offers many advantages not found in similar products on the market. The system has a very fast payback period – an average of one to three years before policy incentives, which is a wise investment choice for building managers looking to improve building energy efficiency and optimize building demand response.
Our ballasts are compatible with Lumenergi's LMCS system and other manufacturers' control systems. The ballast can be operated via DALI or other industry standard 0-10V low voltage control bus. They can be connected to a wide range of voltage inputs, from 120V to 277V or even 48VDC for emergency lighting. Our ballasts, through their microprocessor-controlled sensors, can manage one to three T5, T5H0 or T8 luminaires with just one iB-100 model. This provides high flexibility, significantly reduces inventory costs and avoids installation errors.
In addition, our two-way communication provides additional benefits to building managers who can monitor each fixture, making the entire system as efficient as possible.
Sinclair: What role does the use of intelligent lighting systems have on the overall energy consumption of the building?
D'Amour: By using an intelligent lighting system like ours, it can save 50%-70% of lighting energy consumption, depending on the type of building and the way the building manager chooses the system configuration. It is important to note that the reduction in energy consumption we implement does not detract from the comfort of the residents and the visual effects of the lights. In fact, we have found that many people prefer the illumination provided by our system because it enhances visual comfort and allows everyone to control and adjust the lighting in their personal space.
Below is a list of ways in which intelligent lighting management systems can help buildings save energy costs:
Daylighting: By using an illuminance sensor, the system adjusts the brightness of the room based on natural lighting. Energy saving potential: 35-45% savings in daylight.
Adjusted according to work tasks: Lighting designers can control the lighting of personal space according to the needs of the work environment. If this type of strategy for adjusting lighting control based on work tasks can be implemented, it will be able to save considerable energy costs while meeting industry-recognized, IES-recommended illuminance or other lighting engineer-specified illuminance. Energy saving potential: 15-25%.
Timeline: By using advanced time schedule scheduling, the system can control each luminaire in different areas of the building to provide appropriate illumination at different times, different days, different months, festivals, special events, different seasons, and so on. Energy saving potential: 15-25%.
Lumen management: Lumen attenuation is the loss of illumination as the life of a fluorescent or LED lamp increases. Lumen management solves this problem by reducing the power of the lamp at the beginning of the lamp's use and increasing the lamp's power later in the lamp's use, and always maintains the proper illumination. Luminaires are no longer forced to produce unnecessary lumens to compensate for their later dim. Energy saving potential: 7-10%.
Occupancy Sensing: Turns off the light when the system detects that no one is in a room or area. When the occupants in the building move between different locations, the system automatically provides illumination at the location where the lights are needed, and turns off the lights in the unmanned area, depending on the rules of the user's movement. Energy saving potential: 10-25%.
Personal Control: Everyone can set the brightness of their office or work area through personal client software, web access or infrared remote control within the overall illumination limits set by the system. Energy saving potential: 10-15%.
Load shedding/demand response: load shedding, sometimes referred to as demand side management or demand response, allows for careful adjustment of lighting; setting limits based on building energy requirements; or dynamically responding to emergency signals or real-time electricity price signals so that The actual amount of energy reduction can be monitored, unloaded or reported (measured) and the effect of these measures on the energy consumption of the building system. Energy saving potential: Energy policy refund.
Sinclair: Please tell us about the installation process of the intelligent lighting system. Is it possible to retrofit an existing system? Still have to build from scratch?
D'Amour: One of the biggest advantages of the Lumenergi system is its ease of installation, which can be used for building renovations as well as for new buildings. One or several LMCS controllers can be easily installed in cabinets, each controlling 50,000 square feet (4645 square meters) to 100,000 square feet (9290 square meters). They connect to an LMCS server over the network to manage the building as a whole. The LMCS server can be connected to an existing BMS system via BACnet if needed.
The next step is to install a smart ballast. In the retrofit project, you only need to remove the original ballast and replace it with our more advanced version, then connect it to the floor controller. Each ballast is controlled and operated via a standard DALI bus, allowing the control system to monitor them and control them with a simple 0-10V analog signal.
Once this is done, the building's managers have complete control over the entire lighting system, and each light can be monitored and captured via a user-friendly software platform. The system also has built-in redundancy backup.
Sinclair: How does your intelligent lighting system work with the BMS system?
D'Amour: The Lumenergi system is an important complement to the BMS system. do you know? 42% of the cold load is due to the heat generated by the lighting. Intelligent lighting control can be matched to HVAC systems and reduce the use of HVAC systems.
Our system communicates with the BMS system via BACnet. Through this communication, we make HVAC more intelligent in time. For example, we can transmit our occupancy sensing signals to the HVAC system, which is an air conditioner that can be automatically turned off when no one is present. We can also transmit occupancy sensing signals to the security system to improve the security of the building. In this way, the ubiquitous lighting network can reduce the need for additional sensors and wiring throughout the building. Another more interesting example is that we can provide the demand response information we get from the smart grid to the HVAC system, enabling HVAC systems with offload capabilities for demand side management. As you know, the integration of the LMCS system into a BMS system is very versatile.
