Lumenergi’s Lighting and Energy Management Solutions

Integrated approach saves 50–70% of existing energy spend on lighting

Lumenergi's lighting management solutions, which comprises Lighting Energy Modules (intelligent ballasts) and the Lighting Management Control System, enable building owners to achieve exceptional energy savings while improving the quality of lighting throughout the building.

Significant Savings

The core strategies that drive these energy savings are described below, along with the average energy savings that each strategy can provide. The overall realized savings will depend on the type, size and architecture of the building, as well as the task functions performed by occupants of the building; however, Lumenergi's deep experience in working with dimming technologies, as well as joint research with world-class energy research labs such as Lawrence Berkeley National Laboratories, indicate that such strategies can save building owners between 50–70% of total energy spend on lighting.

Fast Payback Period

With Lumenergi's solutions, most building owners can achieve a payback on retrofit installations in two years or less, before energy rebates! With energy prices trending up in the long-run, investing in a Lumenergi solution today is an enlightened choice that will continue to provide significant returns over the years.

7 Integrated Lighting Control Strategies

controls-daylighting.jpeg1. Daylighting

Daylighting employs sensors and lighting control systems to adjust fluorescent lighting levels according to the availability of natural light during the course of the day. Potential Energy Savings: 35–45% in daylit areas.

controls-tasktuning.jpeg2. Task Tuning

Task Tuning allows lighting designers to control lighting according to task and working environments. The ability to implement this kind of work and task lighting control strategy can save considerable energy when implementing industry recognized IES recommended lighting levels or those levels specified by the lighting consultant or engineer. Potential Energy Savings: 15–25%.

Using advanced scheduling, the system can provide the appropriate lighting configuration for different parts of buildings during the work day, work week and through different seasons. Potential Energy Savings: 15–25%.

4. Lumen Maintenance

Lumen depreciation is the loss of light output as a fluorescent lamp ages. Lumen Maintenance controls solve this problem through reducing power in response to higher initial lamp lumens while increasing power as lamps age and phosphors degrade to maintain appropriate light levels. Designers are no longer forced to over design lighting to compensate for lumen depreciation. Potential Energy Savings: 7–10%.

Lights are dimmed to the off state when the system detects that there are no longer occupants in a particular room or area. As building occupants move from location to location, the system dynamically responds to user-traffic patterns, providing the right-level of light where it's needed and shutting off areas which are vacant. Potential Energy Savings:15–25%.

Through individual software clients, web-based interfaces or IR remote controllers, the personal control capabilities of LUMEnergi's solution allows individuals to personalize the amount of dimming they prefer in their offices or work areas within globally-set system limits. Potential Energy Savings: Varies.

Load Shedding, sometimes termed Demand Side Management or Demand Response, allows lighting to be either adjusted discreetly; on a fixed schedule in response to building energy demands; or, dynamically in response to emergency signals or real time pricing signals to monitor, shed and report (sub meter) on the actual reductions implemented and their effect on building systems and consumption. Potential Energy Savings: Energy Rebates.
