Presentation Overview
Retrofit strategies to achieve energy savings of
50% - 70% on interior lighting and exterior lighting.
Main approaches – Key strategies to explore• Lighting applications
• Lighting Controls
• Case studies
Putting it all together - How to get there• Lighting Audits
• Turnkey Retrofit
• Commissioning / Maintaining
In Oct 2011, FEMP identified 50 recommended projects
Eight lighting projects were sited in the top 20
Many are easily acquired lighting or controls solutions:• Ballasts (Advance Ballasts)
• LED’s (Lumiled)
• LED Drivers (Advance Ballasts)
• Fixtures (Philips fixtures)
• Controls (Dynalite and Philips Controls)
The Philips Lighting EnduraLED A19 Lamp L-Prize• Selected as the SSL product in the Lighting for Tomorrow
competition.

Compared to GSA Base and the National Average
Study was sponsored by GSA and DOE
The fixtures, dimming equipment and installation were all furnished using Philips Government Lighting Solutions products and expertise.
Study conducted by Lawrence Berkeley National Labs with these results.

• Problem Description
– 1.8 million square foot facility with high demand and
dim lighting
– Original lighting included low-bay areas equipped
with 1,370 400W HID systems and high bay areas
illuminated with 576 1000W HID systems
• Solution Used
– Instant on 4-lamp T5HO fixtures
– HBO400 Logistix Pro fixtures
– Motion sensors and electronic ballasts
• Outcome
– Reduced demand by 818kW and eliminated 4.3
million kWh in load
– Saved $450,000
– Improved light quality and visibility

• Description
– 5000+ Existing Parking lot & Pedestrian
luminaires
– Existing system utilized 150 watt & 400 watt
high pressure sodium systems
• Solutions Used
– 90 & 140 watt CosmoPolis and 210 & 315 watt
MCE ceramic metal halide lighting system
• Outcome
– Reduced the Campus energy bill by over
$550,000 annually when campus retrofit
completed
– Changed to 3,000K “white light” from 2,200K
“yellow light” enhancing campus security &
student comfort
– 30,000 hour lifespan dramatically reduced
maintenance costs

Putting It All Together – Key Steps
Lighting/Energy Audit
Solution Design
Turnkey Retrofit
System Commissioning
Service Contracts
Putting It All Together – Lighting Audit
Initial assessment• Energy Reduction Goals / Available Budget
• Required Payback Period
• Utility Rates / Rebates available
Aesthetic Considerations• Current IES Standards
• Fixture Types Desired
• Purpose of Space
Information Required• Floor Plans / Existing Controls
• Existing Fixture Information
• Electrical Plans / Circuiting
Putting It All Together – Solution Design
Identify Lighting Issues Experts recommend most efficient solution
Ensure lighting meets current IES standards, State / Local codes
Target: The right light for the tasks, people, and spaces at hand
Design the proposed solutions. Evaluate lighting studies to determine best strategy
Meet the stated goals without sacrificing performance
Generate the ROI, energy and total cost of ownership studies
Prepare the Retrofit Construction Solution Engineering Drawings
Generate Proposals
Putting It All Together – Turnkey Retrofit
Turnkey retrofit installation services are available
• using local expertise for touch labor to keep costs down
Factory engineer field commissioning of Control Systems
• is included in the retrofit solution
Service Agreements are available
• for maintenance, training or periodic re-commissioning
Putting It All Together – Some Scalable Projects
LED Site Lighting Fixtures – Includes site survey, drawings, 400 fixtures, disposal and labor. • Budgetary Range $500,000
LED Parking Garage Fixtures –Includes site survey, drawings, 200 fixtures, disposal and labor.• Budgetary Range $250,000
Wireless Occupancy Sensor Packs –Includes site survey, drawings, 400 packs, labor and commissioning.• Budgetary Range $100,000
Budgetary Prices based on simple retrofit applications and do not include advanced control options or site specific issues.
The actual cost of surveys is rolled into the project – no out of pocket costs are required to get started.
Putting It All Together – Some Routes
Energy audit services are available on GSA Schedule
• Lighting and control issues can be addressed (GS 21F-0159X)
