Eastern Distribution Center
In 2002, Havertys consolidated two regional warehouses into a new Eastern Distribution Center (EDC) in Braselton, Georgia. The distribution center is an 810,000-square-foot tilt-panel high-bay racking facility that employees 210 people and operates 153 hours each week. The function of the facility is to store incoming furniture and ship to one of four home delivery centers, and/or assemble and prep for shipment to multiple market drop sites and then from there to customer homes in the southeastern United States.
The EDC is Havertys' largest single distribution center facility, and also the company's largest single user of energy in its entire building portfolio.
In 2010, Havertys launched the HVTerra program which helps the company implement sustainable practices in both existing and new stores throughout its portfolio. After achieving significant energy reduction in its stores from LED lighting and HVAC retrofits, Havertys turned its attention towards its distribution centers for additional energy efficiency and sustainability opportunities.More
In 2011, with increased visibility from the energy data and reporting at the launch of its HVTerra program, the Havertys EDC team made overall operational HVAC and efficiency improvements and behavioral changes in efforts to reduce consumption with little or no cost. The increased awareness and sense of responsibility allowed the EDC team to optimize equipment, shift performance, and make operational process improvements. Additionally, the team replaced dated battery-operated equipment with more efficient equipment with fewer batteries. These changes led to a decrease in consumption over time, as well as an opportunity to look into capital improvements to adopt further energy conservation measures. The operational efficiencies implemented from 2011 to 2015 have helped to offset increases in consumption and rate costs and represent a 10 percent energy reduction.More
Havertys achieved significant energy savings at the Eastern Distribution Center through three major lighting upgrade projects. In August 2015, the existing metal halide lighting in the bulk storage area was replaced with more energy-efficient LED high-bay fixtures. In January 2016, additional lighting improvements were made which included the replacement of existing high-pressure sodium high-bay rack and aisle lighting with LED fixtures. These energy efficiency projects and other operational changes at EDC have collectively improved EUI by nearly 30 percent since 2011 (compared to year-end 2018).
In spring 2019, the fluorescent lighting in the prep area and recycle areas of the facility were replaced with LED at a project cost of $200,000. An additional 15 percent improvement in EUI is expected from the completion of the most recent LED lighting upgrade in comparison to the 2014-2015 baseline period before the first LED projects were completed.
While electrical consumption has dropped nearly 30 percent since LED has been introduced, electric rates have also risen by about 7 percent. Overall, the annual electrical cost has been reduced about $170,000 which has absorbed much of the increase in electrical energy rates. Gas consumption increased during this period due to the reduced heat gain by the new LED lighting fixtures (about $12,000 annually), leaving a net savings annually of $158,000. The return on investment for the LED projects overall is 3.5 years based on the avoided cost when factoring in the rising energy prices.
|Savings Measure||Project Cost||Implementation Date||ROI||O&M Savings|
|Operational Efficiency Changes||Low Cost/ No Cost||2011 - 2015||Offset 7% increase in energy costs||10% EUI reduction|
|LED Lighting Upgrade - Bulk Storage||$351,800||August 2015||3.5 years||30% combined EUI reduction|
|LED Lighting Upgrade - Rack and Aisle||$248,200||January 2016|
|LED Lighting Upgrade - Prep and Recycle||$200,000||April 2019||2.7 years||15% expected EUI reduction|
The LED upgrades have been well received by the distribution center associates and management. Both groups feel that LEDs provide higher quality lighting, along with the benefit of increased safety and visibility (as well as less energy consumption). Maintenance savings from the LED bulb life and reduced material and labor costs provide positive impact to both safety and facility operational cost, and have not been included in the ROI expressed above.More
