Smart lighting, connected lighting for smart buildings
With connected lighting, the building's lighting system no longer produces not only light, but also data. Collecting and analyzing this data opens up many opportunities in terms of energy performance and building management. Energisme accompanies you in the management of data, from collection to exploitation.
Qu’est-ce que l’éclairage connecté ?
Generally speaking, connected lighting refers to lighting equipped with IoT sensors to collect data. Associated with LED technology, smart lighting allows to :
- remotely control lighting
- adjust the light intensity according to the occupation of the spaces and the uses of the occupants
- achieve energy savings
For example, the lighting fixture contains motion sensors to light a room according to its occupancy. These sensors are connected to a dedicated application that analyzes the data to rationalize the building’s lighting.
In the professional building sector, the Internet of Things is opening up even wider opportunities. Connected lighting systems form an ideal sensor network with a very dense mesh throughout the building.
The data collected by these sensors can of course be used for intelligent lighting. But, to go further, it is also possible to share this data with other technical equipment to improve the energy performance of the building in a more global way.
Very often, the implementation of a smart lighting system is the gateway to a broader smart building approach. Through its software solution called N’Gage, Energisme accompanies you in this transition. As a data specialist, we help you collect massive data from connected objects such as lighting systems. Then, the platform centralizes, processes and analyzes the data to transform them into decision support.
What are the challenges for smart buildings?
- The autonomous lighting of the building
- Significant gains in energy consumption
- Connected lighting, a pillar of smart building
The primary benefit of connected lighting is the automation of lighting.
Building occupants no longer have to worry about turning lights on or off.
The lighting automatically adapts to the occupancy of the room, to the natural sunlight or to the occupants’ uses.
Smart lighting contributes to improving the energy performance of buildings.
The potential for energy savings is significant in the building sector, which is particularly targeted by energy transition policies.
Connected lighting, combined with the development of LED technology, contributes to a significant reduction (in the order of 50-80%) in energy consumption.
Intelligent lighting is also and above all a gateway to the connected building, its uses go far beyond lighting.
Changing lighting fixtures is a source of savings. But it is also a step towards a more intelligent building, optimized thanks to data. Indeed, the IoT sensors in the lighting fixtures collect data not only on lighting but also on the occupation of spaces.
The collected data (time of presence, occupancy rate, occupants’ uses,…) can then be centralized in the Energisme software platform. They then become interoperable with the data of other equipment or with external data sources. In a logic of open data, they can be made available to any service provider likely to participate in the improvement of the energy performance of the building.
For example, if connected lighting data shows that a room is systematically unoccupied over a given period of time, there is potential for further energy savings, this time in heating or air conditioning.
Towards better building management
A connected lighting system can collect a whole set of data about the building:
- Space occupancy
- Room temperature
- Humidity level
The processing and analysis of this data in the Energisme platform feeds the automatic control of the building’s lighting. Connected lighting therefore meets the challenges of energy efficiency but also comfort and safety of the building and its occupants.
The interoperability of N'Gage
The interoperability of N’Gage, Energisme’s platform, allows it to collect all data from heterogeneous sources (IoT sensors, smart office software, BMS, meters, etc.). It can then intelligently cross-reference data related to lighting intensity, occupancy rate, room temperature or humidity level and contribute to a better management of buildings on several levels:
Smart lighting systems do more than just control lighting. The data collected also participates in the optimization of heating, air conditioning and ventilation systems.
This data forms a basic foundation for an energy audit and for any building energy renovation action.
The IoT sensors can also feed a security system by detecting intrusions or suspicious activity (for example, a presence at an unusual time)
Occupancy data provided by connected lighting indicates whether a room is occupied or not. They thus facilitate access to unused spaces.
In the same way, they also help rationalize the occupation of workstations.
Information on room occupancy times can also be mobilized to adapt the rounds of cleaning staff.
The IoT is the main means of collection but there are others to retrieve the data.
It can come directly from the meter manufacturer or from the BMS.
The solution then allows to:
