• 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

• 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

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
