Paul Holliday, PEDirector of EngineeringLowe’s Companies, Inc.


• Lowe’s has been helping our customers improve the places they call home for more than 60 years

• Founded in 1946, Lowe’s grew from a small hardware store to the 2nd-largest home improvement retailer worldwide

• Lowe’s operates more than 1,725 stores in the United States, Canada, and Mexico

• Ranked 49 on the FORTUNE® 500 (2010)

Lowe’s Company Overview

Lowe’s joined REA to participate in exploring best practices and promoting research for energy-efficient design and operation for retail facilities


We believe building a healthier business and a healthier environment go hand-in-hand. Lowe’s cares about our company’s activities and how we impact the earth’s ability to provide natural resources to future generations. For that reason, we continually examine opportunities to reduce our environmental impact while providing the products and services our customers have come to expect.

Lowe’s Sustainability Commitment


• In early 2010, Lowe’s completed a sales-floor lighting retrofit that started five years ago, replacing HID fixtures with high-bay fluorescent fixtures

• 3,234,204 lamps were installed

• Energy savings are estimated at 546 million kilowatt-hours annually, or enough to power more than 50,000 homes for an entire year

Lowe’s Continuous Improvement


• Two stores are fully daylighted and serve as tests for evaluating:– Controllability of lights using photo cells

– Maintaining the customer’s experience

– Measuring true energy savings through submetering

• Approximately 210 skylights are installed at each location

Daylighting Remains an Option


Retailer Energy Alliance (REA)

• First energy alliance launched by DOE

• Benefit from technical expertise of DOE, national labs

• Serves as information network for best practicesand ideas

• Constitute single voice for technologies/services needs

• Help shape federal building R&D

• Provide examples for businesses, communities, and public institutions


REA Member Benefits

• NREL, PNNL (national labs), and think tank support

– These folks help qualify technologies and bring single point of contact for manufacturers, new specification development, etc.

• Supplier summits — focused work with manufacturers and service providers — including ways to assist with technician training

• Member of the REA Steering Committee

• Actively participates on three Project Teams (Lighting, Whole Building Systems, HVAC)

• Worked/working on: technology and system specifications, exterior/interior LED fixture tests, and online calculators for lighting and HVAC analysis

• Enjoys the open dialogue on energy-saving opportunities and lessons learned

Lowe’s Involvement in REA


• Return on Investment (ROI)– Tough to convince management

that energy conservation measures (ECMs) are attractive and our analyses are accurate

• Tracking the savings from ECMs– Staged implementation requires

multiple runs of modeling to analyze each ECM

– Additional energy models are required to analyze synergies of implementing overlapping ECMs

Challenges for Lowe’s

Evaluate ECM

Energy Simulations

Financial Analysis

Capital Budgeting

Measuring Performance

Asset Management

Overlapping ECMs

Tracking ECMs — as lighting energy decreases, another ECM becomes focus of next evaluation. Notice HVAC taking a larger portion of the pie and becoming the next target for energy reduction.

• General lighting accounts for two-thirds of lighting energy

• No feasible alternative to high-bay fluorescent fixtures at this time

• Daylighting requires careful placement — ensure adequate coverage in all areas

• Lighting controls must be maintained– Photo cells need to be calibrated– Lighting controls need monitoring for

optimum energy savings• Exterior lighting is small piece of pie,

but has huge impact on peak demand


• 75% place high emphasis on reducing energy for general lighting

• 55% place high emphasis on reducing energy for display/produce lighting

• These two areas represent 75% of lighting energy consumed by REA members

REA Lighting Challenges

REA Lighting Interests Questionnaire


An Emerging Challenge for Retailers• Funding for energy conservation measures — need to convince

corporate finance department to release money for our projects

• Financial planners are not technically savvy

• As technology advances, it becomes more and more difficult for financial departments to understand added value

• Need to develop best practices for presenting a business case

• Most importantly, we are challenged to illustrate the value of our time that is invested in CBEA and REA activities



Summary of Members’ Lighting Challenges• Members recognize lighting is a major contributor to energy

consumption

• Members desire to obtain advanced technology for lighting solutions and to reduce their lighting loads

• Members have implied that general and display lighting are areas that should receive most attention

• Members express most interest with two technologies

1. Improved fluorescent2. LED fixtures

• Members agree that cost analysis, fixture performance, and ROI are critical to implementation of new and different technologies
