Design Overview
Intelligent fixtures ─ simple deployment
 MPU‐controls wireless sensor hard wired to each fixture


Optimizes individual lighting comfort and space needs Stand‐alone wired control – not dependent on server connectivity Sensors monitor energy, temperature, occupancy, and light levels
 Performance metrics data show a 50‐75% energy savings



Granular task tuning and daylight harvesting
Confirms for occupancy the smaller the zone, the larger the savings Measurement & verification for individual fixtures or selectable groups  Enables informed decisions: facilities, security, life safety

Intelligent Fixtures Maximize Savings
Sensor control profiles and dimming capability enable tuning to appropriate light‐levels for people and space.  Task Tuning (30‐40% Savings): Lights degrade over time so architects over‐light to meet code. Lower light Min/Max range.
 Daylight Harvesting (0‐10% Savings): Automatically adjusts based on level of ambient light present/monitored by sensor.  Occupancy Control (40‐60% Savings): Lights are only on where and when needed. Adjust time window and sensitivity.  Total Combined Savings = 50‐75% Plus

Controls to brighten and dim lights are sent over a hard-wired connection
to the ballast, not the wireless network. This provides high reliability and
cuts wireless chatter to a minimum. There is no single point of failure, and
a network outage cannot bring the Enlighted system down.

Each Enlighted device communicates people-centric data occupancy, motion, light and temperature - wirelessly through a
gateway to a central server.
Occupancy, motion, light and temperature data is aggregated by
the Enlighted Energy Manager Server.

Accessible via a standard Web browser, Enlighted Energy Manager
software presents real-time lighting energy data and reporting. The

Value for Business Operations & Employees
29
Value for Cross‐functional Teams • Operations: $$$ dashboard reports measured savings. Easily reconfigure fixture profiles as needed for space redesigns.
• Energy Czar: kWh dashboard reports measured savings. Control design increases employee conservation awareness. • Sustainability Team: CO2 dashboard reports carbon footprint savings from measured lighting efficiency. • Building Engineer: Easily resolve employee glare/light‐level complaints. Proactive maintenance (fixture failure reports).
• Real Estate/EHS/Security: Occupancy monitoring; space utilization/emergency response/unauthorized occupancy. • Employees: Adjusted lights improve comfort & productivity. © 2012 Enlighted, Inc. All Rights Reserved.
30
Employee Experience at HP • Reduced light levels were not noticed: System was activated with area occupied ─ verbal survey confirmed no awareness. • Disabling wall switches was not noticed: A testament of effectiveness ─ no communica on and no complaints.
• No complaints, loved personalized tuning:  Migraine‐susceptible people requested reduced light level; 35% max. (2 people, 1 previously blocked light with hat), 20% max (2 people).
 Monitor glare problem was resolved; 20% max. (1 person)  Research engineers working odd hours requested custom profiles for 2‐4 fixtures around them (2 people).  No more light switch wars caused by zoned lighting. • Safety: When working alone, lights turn on if people approach.
 Those working late appreciated this design function. © 2012 Enlighted, Inc. All Rights Reserved.

California 2013 Title 24 Code:
takes effect January 1, 2014
California Technology Lighting Center (CTLC) website provides a summary of changes to mandatory title 24 lighting requirements.
Download “Learn what’s new in the 2013 title 24 code” at: http://cltc.ucdavis.edu/content/view/1256/485/
39
39
What does it mean for the industry?
 Title 24 requires modifications  Dimming or step ballasts are now required
 Each fixture must be controlled
 Day lighting and occupancy sensing required
 Open Automatic Demand Response (OADR) control required
 User control at room level or private office
 Impact “normalizes” lighting control industry to a fixture by fixture strategy


Retrofit requirement for scope above 10% lighting modification
Cost of dimming ballast and retrofit labor become standard scope
 Fixture‐level control strategy becomes least costly
 No additional line voltage wiring required
40
What does it mean for Enlighted?
 Our architecture becomes necessary to meet code
 Wireless ‐ fixture based lighting control solutions become extremely attractive and potentially the industry standard

Whole solution cost for Enlighted becomes very competitive against any solution  Our solution is future‐proofed against new T‐24 now
 Consider specifying now to avoid retrofit project rework later
41
Solution Benefits after Title 24
 Less costly than a wired system
 Provides a very fine level of control of all the lights
 We can tune an individual fixture or group
 We meter what we control
 Capable of the deepest lighting control savings below the new T‐24 levels
 Provides the data at a smaller marginal cost than before T‐24


Adding gateways, cables and an EM to a site is all you need
The dominating costs are the fixture retrofit – they are required now
 Maximize whole building energy efficiency: the data can be integrated into other control systems (HVAC, DR, Security, etc.)

Customer Case Study
Beginning in 2011, NEEA partnered with lighting manufacturer Enlighted to launch a
proof‐of‐concept study of occupant and lighting controls at the individual lamp level. Results of the study are expected to be published June 2013: http://neea.org/initiatives/emerging‐technology/luminaire‐level‐lighting‐controls
