Innovation and added value services
The use of solid-state devices like LED, light control modules and lighting fixtures, in the form of a hybrid distribution layer, where the low-voltage (typically 48 VDC) power supply does not replace AC in a building but complements it, as proposed in the EDISON project. The DC lighting infrastructure allows to efficiently aggregate or eliminate multiple AC to DC conversions, thereby making devices simpler, safer and more flexible in use.
By providing convenient direct access to safe power (low-voltage DC), such a system will:
- make easier and less expensive to install lighting fixtures, sensors and other devices and simpler to repurpose and reconfigure future renovations without building or device re-wiring, so buildings resume operation sooner;
- help to dramatically reduce technology upgrade costs for new technologies such as LED lighting, while reducing energy consumption via state-of-the-art device control and digitally integrated load and source management that enables higher resolution control, metering and demand response;
- promote sustainability with simpler system devices that have fewer materials without AC to DC conversion components and through use and reuse of system devices with interoperable plug-and-play mobility and simplicity;
- facilitate the direct connection and efficient use of energy from solar, wind, or other native DC alternative energy sources;
- allow facility technicians to quickly and safely move or re-install lighting fixtures and other low voltage devices without the need to shut down branch power lines or otherwise significantly interrupt area occupants.
In addition, the “PowerLAN” developed in the project, spread everywhere in the building, will help in promoting an extensive use of “simple remote energy smart meters”, thanks to such an integrated power-data network, devoted to illumination.
EDISON approach allows to implement a lot of innovative value-added services aimed to solve the most difficult challenges in building lighting systems management at once, providing real-time view into the way public spaces surrounding the buildings, parts of the buildings, offices, etc. are being lit, heated, cooled and occupied.
An high-density sensors network eliminates the need for time-consuming occupancy/lighting sensor calculations for daylight harvesting. The consequent distributed network of sensors provides more than just advanced lighting management.
With a fine-grained level of monitoring throughout a building, the lighting network monitors, records and provides alerts and information for:
Fixture-Level Management: Single-room light control, so individuals benefit from optimal working conditions.
Security: Detect instantly locate occupants.
Meeting Planning: Actual conference rooms availability based on real-time occupancy, not calendar scheduling.
