Babel Buster Network Gateways: Big Features. Small Price.
In a world in which people, places and things are becoming increasingly connected, your building’s energy systems need to be connected as well. Unfortunately, less than 2 percent of the 80 billion square feet of existing commercial real estate in the U.S. take advantage of distributed lighting controls to save energy and reduce costs and carbon emissions.
Lighting alone accounts for 30 to 40 percent of a
commercial building’s electrical use, so the inability to control lighting
through a distributed intelligent network to reduce costs is a tremendous missed
Wiring and installation costs are often cited as major barriers to deploying advanced controls in existing buildings. Adura® Technologies, which designs and manufactures turn-key, full-featured digital lighting and energy management control solutions, overcomes this barrier by connecting lights with robust, secure distributed wireless controls that lower electricity costs 30 to 70 percent, while enhancing the long-term value and viability of buildings. By going wireless, the cost drops dramatically and disruption to building occupants during installation is minimized.
The Adura LightPoint System™ (ALPS™) control platform provides unprecedented management over commercial building lighting. A key component of the system is the Adura Light Controller™ which can control one or more ballasts or other lighting loads to provide the ultimate in granular control. No longer does an entire floor of lighting need to be wasting energy only because a few lights are needed. The distributed control platform communicates with field devices such as switches, motion sensors, light sensors and our enterprise web software to provide flexible scheduling, daylight harvesting, occupancy control, personal control and load shedding.
Beyond controlling lighting, the ALPS Enterprise Database tracks and monitors energy use, carbon footprint and peak load and shows users when and where they are using energy. It also can provide valuable predictive maintenance information including reports on failed lamps and ballasts.
ALPS is easy to install and use. In fact, it takes just minutes to install our controller or sensor in a light fixture or switch. The Light Controller even comes with magnets for tool-free installation.
Existing daylight and motion sensors can be wirelessly integrated into the system or, for ease of installation, We can supply the devices, which can be added “lick-and-stick”- style to the network. The sensors are battery-powered with a minimum five year life.
Wireless Mesh Network
The ALPS platform is a distributed wireless mesh network, based on the ZigBee® protocol. Field devices are connected to the Internet by a gateway. That means that, at an enterprise level, control scales from a single device to a room, a floor, an entire building or even a campus.
Mesh networking provides highly reliable control by
enabling multiple paths for the data to flow between sensing and control
elements on the network. The mesh is also self-healing so that if one path
fails, the network will re-route the data to ensure the integrity of the
Additionally, a ZigBee mesh network is easily expandable. Each new node is automatically discovered and can be configured with the appropriate control action.
Finally, if a facility is renovated or walls are moved, the entire control network can be easily reconfigured from a central location with no need for rewiring.
ALPS is also light source agnostic – it can work with fluorescent, incandescent, CFL, HID, LED or any other type of lighting.
Energy Management Dashboard
A powerful feature of Adura’s browser application is an energy dashboard that enables a wide range of management options. The dashboard provides immediate and graphical feedback on energy savings for an entire system or a specific area. Energy savings can be viewed in terms of monetary savings, carbon emissions or kilowatt hours.
ALPS enables facility managers to implement dynamic lighting control, including
scheduling by time or event, occupancy, daylight, task-tuning and personal
control. There is even an astronomical clock that can be used for automatic
Lights can be dimmed, where such capability exists, or individual ballasts in fixtures can be shut off. Such granular control allows for tremendous lighting energy savings. Spaces can frequently be lit at levels well below their installed capacity and are often more comfortable for the occupants as a result.
While central control is critical to system efficiency and effectiveness, ALPS also provides local overrides to meet personal requirements. Individuals can be given the use of simple wall switches, personal remotes or web aplets to adjust lighting to their immediate needs. Since ALPS provides an individual IP address for every controller, any device can be controlled by authorized users through a secure web interface. For example, someone working in a cubicle late in the evening when the rest of the office floor is empty can turn on lights just in his or her area.
Just as important for management purposes, ALPS has a full-featured enterprise application that collects historical information for analysis of energy consumption, provides administrative and user security levels, performs administrator override of all system functions, sets up lighting groups behaviors, alerts users of lighting and system alarms and has a rich set of reports.
All data in the network is encrypted and there are extensive security features for user access to the system. Management can set access levels from full administrative control to a single user being able to control a single light fixture
Another key ALPS feature is its ability to support automated demand response via a signal from the utility or by an e-mail where the system administrator can set the demand response level. The system can be configured such that there is limited user override capability during a demand response event.
This same functionality can be used to manage peak demand. Users can program the system to receive a signal from their smart meter when a peak consumption level is about to be exceeded and automatically execute lighting control to manage the peak load.
Beyond lighting controls, ALPS provides a platform for the management of other building functions. Adura already has partnered with Cypress Envirosystems to provide HVAC monitoring and control. Since lighting and HVAC comprise 60 percent of a buildings energy use, the savings potential is significant – up to 50 percent, according to estimates by both companies.
In fact, just about anything that can be outfitted with a sensor or controller can be integrated into the system, including air quality monitors, HVAC components, security systems, fire extinguishers, etc. That’s our long-term vision – a total building system management system, with mass controls at the enterprise level that can be tailored to a facility’s specific needs.
Adura has proven that its system works in numerous case studies.
In 2008, the California Energy Commission’s Public Interest Research Program issued a technical brief entitled “Wireless Lighting Controls Make Retrofits Practical” in which it concluded: “An innovative wireless light-control, monitoring and management system developed by Adura Technologies is easy to install, cost-effective and can provide significant energy savings.” The conclusion of the study came from work that a team, including Adura’s founders and the University of California, Berkeley, performed at two libraries on the campus. Adura’s wireless control system was installed in facilities where lights burned 24 hours a day because the only controls were in circuit breakers in a locked closet or near a skylight. Our wireless solution showed a 65 percent reduction in cost and resulted in a nearly instant payback.
In 2009, we completed a project for Webcor Builders
at one of its facilities in Hayward, Calif. The 2,300-square-foot open space was
occupied by a mix of project and administrative personnel and the occupancy
pattern changed constantly. Many employees were in the office part of the day,
but in the field the rest of the time. With no individual controls for the
overhead lighting, lights burned at full brightness all day. We installed
wireless controllers in each fixture and gave remote control devices to each
cubicle occupant. As a result of employees turning lights on when needed and off
when they left, the facility saved 65 percent on lighting.
In two other studies last year by Pacific Gas and Electric, Adura lowered energy use in at an Alameda County Water District facility by 70 percent and met utility company requirements for demand response.
In summary, distributed wireless mesh controls provide exciting new opportunities for improving energy use efficiency in commercial buildings. They are particularly attractive for existing buildings, where retrofitting with traditional wired systems can be expensive and disruptive.
Adura’s solution is cost-effective for retrofits, renovations and new construction. With the wireless solution, building owners, tenants and facility managers can implement energy efficiency and load curtailment strategies to reduce operating costs and carbon emissions at a third of the cost of traditional control systems.
