7 Conventional Lighting Controls
Low voltage relay based controls
• Most prevalent form of facility wide lighting control • Turn lights “ON/OFF” by lighting circuit/switch leg (zone) based on time schedule
Occupancy Sensors – Line level
• Automatically turn lights off if occupancy is not detected • Typically connected at the switch leg (or circuit) for room level control

Conventional Lighting Controls....(cont’d)
Limitations • No ability to address & control individual fixtures − Zoning restricted to circuit leg
• No workspace or task specific control − i.e. tuning light levels based on use
• Lack of centralized “intelligence” to allow deployment of combined energy management strategies
• Limited ability to integrate or share data with other building systems such as HVAC, Security and Fire

12 Wireless Hop Routing
13 Popular Addressable Control Methods - Lighting
Wired • Addressability built in ballasts • Communication & power in one cable • Requires interface device to 0-10V ballast for addressability • Networked via low voltage field bus
Wireless Proprietary or open protocol (ZigBee or other) • Typically use wireless interface devices together with gateways
14 Building Automation Protocols
1-Wire – from Dallas/Maxim BACNET C-Bus CC-Link Industrial Networks DALI DSI Dynet EnOcean KNX – previously AHB/EIB LonWorks Modbus RTU or ASCII or TCP oBIX HDL-Bus- main protocol for HDL home automation system. VSCP xAP – Open protocol X10 – Open industry standard Z-Wave ZIGBEE – Open protocol INSTEON DMX http://en.wikipedia.org/wiki/List_of_automation_protocols
15 Objective 2
Explore and understand how lighting controls are affected by architecture and space
16 Building Interior
17 Design Considerations
• Furniture style, placement • Room surface finishes • Office cubicle partition height • Walls and ceilings reflectivity • Work surface placement – reduce shading requirements • Glare • Too many windows can cause thermal issues
18 Open office management
•Design Considerations •General Office Lighting •Task Lighting
Right amount of Light At Right Time At Right Place
19 Building Design
20 Design considerations
• Style of building • Façade direction • Climate • Building components (such as windows and skylights) • Lighting controls
21 Software based System Control - Daylight Harvesting
• Photo sensor can be used to report light level information – Individual fixtures can be configured to have a unique response to sensor signal – Individual fixtures dimming based on proximity to natural light source
Lights ON due to time delay
22 Objective 3
Evaluate the cost benefit and impact of increased interaction with the lighting control system.
23 Why use lighting controls?
37% Energy Use • Commercial building lighting, 37% of consumption
• More mandates for controls
• “Green” building incentives
24 Energy Management System - Overview
Six energy management strategies
25 Energy Management Strategies for Addressable Lighting Control
Smart Time Scheduling: In areas of a building where occupancy sensor control is not appropriate, time scheduled switching or dimming of lights can be employed for zones as small as a room or even individual light fixture.
Daylight Harvesting: Through the use of photo sensors, light levels are automatically adjusted to take into account ambient natural sunlight entering the building. Appropriate light levels are maintained and artificial lighting is dimmed when necessary.
Task Tuning: Setting default (maximum) light levels to suit the particular task or use of a workspace in order to eliminate over lighting.
26 Energy Management Strategies for Addressable Lighting Control
Occupancy Control: Through the use of occupancy sensors, lights are automatically turned on or off or dimmed based on occupancy detection.
Personal Control: Through the Personal Control Software, individuals can control (dim) the light levels in their workspace to suit their personal preferences from their desktop PC.
Variable Load Shedding/Demand Response: The automatic reduction of electrical demand in a building by shedding lighting loads dynamically (through dimming) either to shave peak demand or to respond to a utility price or demand response signal.
27 Implementing an Addressable Dimming Control System
• A fully software based system
Lights ON Lights OFF
Occupancy Sensor: Space not occupied Lights OFF Lights ON
Lights ON due to occupancy sensor time delay
28 Software based System Control Smart Time Schedule
• Ability to create time schedules for each functional area of a building as well as down to individual fixture level – Availability of Outlook style programming
Lights ON Lights OFF
29 Software based System Control Task Tuning
• Ability to task tune each fixture in a facility on an individually addressable basis via software
Lights ON Lights OFF
Lights ON due to time delay
30 Software based System Control Task Tuning….(cont’d)
• Task tuning a zone is shown below:
Lights ON due to time delay
31 Software based System Control Occupancy Sensing
• Occupancy sensor can be used to report occupancy condition – Fixture control is possible via software configurable responses
Lights OFF
32 Software based System Control - Personal Control
• Allows control down to individual fixture level – Possibility of setting upper light level limits via software – Easily accessible controls via PC, IP phone, etc.
33 Software based System Control Load Shedding/Demand Response
• Lights can be made to “DIM” selectively by lowest priority areas first
Different fixture colors represent different load shedding groups
Lights ON due to time delay

Software based System Control Load Shedding….(cont’d)
• System can be made to respond to information from a demand meter, a real- time pricing signal, or a signal from building or energy management systems.
Occupancy Sensor: Space not occupied Lights ON

35 Software based Reporting - Energy Analysis
• System can be made to report energy usage down to the individual fixture level – Energy saving by each energy management strategy can also be displayed
36 What’s Next?
•Continuous Commissioning •Learned Behaviors •Optimizations •Global System Changes •Occupancy Detection to Vacancy Detection •Vampire Control •Interoperability
