Evolution Lighting

Andrew Parker

Until recently, lighting controls were predominantly systems of relay panels with low voltage switches and some form of scheduling or time clock. Occupancy sensors provided automatic switching of relays based on detecting the presence of a person in the space. These systems used line and low voltage components, but the communication technology was based on an analogue platform and typically a high (on) or low (off) signal. The technology limited the type and amount of data that could be exchanged, but was essentially an open protocol that allowed a high degree of compatibility between manufacturers.

Analogue wiring was cumbersome and usually required low voltage wires to be “homerun” connected from each occupancy sensor or low voltage wall switch back to the relay panel. The connections within the panel, usually defined (or limited) the associations between the devices and the zones that they controlled.

What changed?

Technology innovations have brought about a revolution in lighting controls by leveraging a change from analogue to digital communications hardware and protocols. The result equates to simplified installation and increased capabilities.
Energy codes have also become more stringent in a stepwise progression with available technology and in response to increases in demand. While it was once enough to add occupancy sensors to automatically turn lights on and off, the new codes require far more, including:
• manual “on”
• bi-level lighting via switching or dimming
• automatic ‘off’ by time schedule or vacancy sensor
• daylighting, under certain circumstances

Examples of updated codes are:
• Ontario Building Code Supplementary Standard SB-10
• ASHRAE 90.1-2010 Standard for Energy Efficiency for Commercial Buildings
• Canada’s National Energy Code for Buildings NECB 2011

Digital vs. analogue
Digital communications protocols and hardware simplify the architecture of systems designed to meet the new requirements. Added intelligence allows hardware devices to be integrated (e.g., two or three relays in one “powerpack”), and it simplifies installation by allowing the daisy chaining of devices rather than the customary homerun wiring method. In addition, the sequence of operations may be programmed by software rather than defined by wiring or dipswitch settings. Digital technology makes addressable devices and wireless mesh networks feasible and further enhances capabilities by allowing local dimming solutions that don’t require a large dimming panel infrastructure.

But while the perceived advantages of digital are indisputable, available technology is also facilitating a departure from previously established standards and a proliferation of proprietary systems. This divergence is likely to continue and will further constrict interoperability among manufacturers until the market drives a change.

Fortunately, proprietary communication can be adapted to include dimming drivers or ballasts that use open protocols such as 0-10V or DALI. These systems can also be adapted via gateways to other building systems using common building automation protocols such as BACnet or LONworks.

Wireless technology
Wireless technology promises a further simplification of control systems, allowing for less time, and wire, to install. A number of factors must be addressed, however, when considering wireless, including:
• The design of the system. Is it open protocol, allowing for interchangeable components and manufacturers, or is it proprietary and designed as a single system? Think PC vs. Mac.
• Power supply. Is it self-powered, wired, or does it require batteries?
• Is it secure? Since the control is broadcast over the air, can an outside “hacker” take control of the lighting or, worse, use the system as an access point to the computer network?
• And reliable? Can the system rebound from loss of communication or loss of a device on the network?
• Interference. Is the system susceptible to other systems’ radio frequency interference (RFI) or unintended electromagnetic interference (EMI)?

New wireless protocols
EnOcean is a technology supplier of energy harvesting (self-powered) wireless modules to OEMs. It is based on the open standard ISO/IEC 14543-3-10, Wireless Short-Packet (WSP) Protocol and is interoperable among different manufacturers and devices. Used in switches, sensors, gateways and more, it is notable for its battery-free wireless light switch.

ZigBee is an open standard, RF (radio frequency) based protocol that uses low-power digital radios at a low data rate. The protocol provides long battery life over a secure digital network. It is based on the IEEE 802.15.4 standard for wireless personal area networks (WPANs), and commonly used for indoor and outdoor lighting fixtures, sensors and switches. It is notable for its self-organizing mesh network. To ensure compatibility, products using the technology must be ZigBee certified.

Software applicationsand interface
As the complexity of control systems increases, efficient software with user-friendly interfaces becomes paramount. Applications, especially browser-based or mobile, have flourished. Central control via drop-down menus or interactive floor plans is in widespread use. In addition, touch screens and personal apps can provide local control from a user’s workspace. Software offers much more than just lighting system monitoring, with additional features like operation, configuration, energy reporting, outages and lumen maintenance reporting topping the list of added intelligence.


SB-10 Code update
Effective January 1, 2014 and included in Volume 2 of the Ontario Building Code 2010 revision, Supplementary Standard SB-10 has been updated to include the 2011 National Energy Code of Canada for Buildings as a compliance path. The updated code also makes changes to the ASHRAE 90.1-2010 prescriptive compliance path, including:
• excluding the requirement for automatic receptacle controls in private and open offices
• clarifying the surface parking area lighting control requirement to reduce lighting power by 30 per cent within a zone of lighting. The code previously implied the stepping down of lighting power within each fixture
• eliminating stairway lighting controls where lighting has been designed to meet minimum levels required by the building code

The future of controls
So what will the future of lighting controls look like? Fixtures with dimming capability and integrated wireless controls are already being introduced to the market to provide cost effective personal control in individual workspaces and to enhance energy savings. In addition, building design is providing better access to ambient sunlight, requiring better daylighting systems to capture the energy saving opportunity. Addressable dimming systems will unobtrusively maximize the effect.
Other anticipated advancements in technology include software that learns operating patterns and suggests ways to maximize energy savings. Time wise adjustment of correlated colour temperature (CCT) to match our circadian rhythm is expected to improve hospital recovery times and provide more comfortable lighting. Also, load-shedding functionality to ease supply shortfalls is becoming feasible and will be a better alternative to unscheduled outages.

Eventually, a balance of open protocols and proprietary systems will facilitate the integration of these new applications and gently wean us off the most widely understood, open protocol, analogue control – the line voltage toggle switch!
