Products and Services: Negawatt Technologies develops energy management control system components for use in office and institutional building energy management systems. These components include ASIC based dimmable fluorescent lamp ballasts with current carrier communication capability to interface to zone controllers and central control computer systems.
The advantages of dimmable electronic ballasts for lighting include:
- lower enegry costs through setting a lighting level that is adequate for
- lower energy costs through daylight harvesting which reduces artificial
lighting when adequate daylight is available.
- lower energy cost through reducing light levels for areas that are not
occupied (central system calendar as well as local occupancy sensors).
- lower energy cost through control of minimum lighting levels for
after-hours security lighting.
- lower maintenance costs through increased lamp life because of proper soft
start* of fluorescent lamps and maintaining cathode heat* while lamps are
The advantages of a controllable lighting systems for wide-area energy
- demand side power consumption control to minimize peak power demand
results in lower energy costs per site.
- by connecting into utility provider demand management systems entire
buildings / facilities / enterprises can have the lighting load reduced by
up to 30% during periods of peak demand to minimize brown-outs or system
* Soft Start and maintaining cathode heat is provided by the Application
Specific Integrated Circuit (ASIC) that was developed by Negawatt
Technologies. US, Canadian, and international patents have been granted
for zone controlled lighting systems based on the Negawatt ASIC technology.
The products developed are being licensed to OEM manufacturers and distributors in North America.
Negawatt will also provide contract product development services in related areas
such as: occupancy sensors, daylight harvesting sensors, zone controller interface to HVAC, HVAC controls for energy management, current carrier communication applications to building controls, interface to security systems and analog ASIC designs related to switching power supply and current carrier communication electronics.
