Multi-site retailers are under tremendous pressure to increase sales, cut costs, and provide shareholders with consistent annual revenue and earnings growth. In turn, the refrigeration contractors who service those store sites must do all they can to help their store customers conserve energy.
Here are seven strategies that retailers and their servicing contractors can use to optimize their energy spending, while maintaining a customer-focused retail experience.
1. Design for Energy Efficiency
• use only the most appropriate energy-consuming equipment
• base decisions and selections on total life-cycle costs
• allow for operational flexibility.
When selecting HVAC and lighting systems, retailers should think in terms of total life-cycle costs—the costs involved in purchasing the equipment and operating it over a period of years. Reliable equipment that runs efficiently might cost more up front but can produce energy savings from Day 1 of operation—savings that reduce the overall cost of the equipment in the long run.
2. Upgrade for Increased Energy Efficiency
3. Use an Energy Management System
• Retailers can establish operating parameters for the energy systems at their facilities
• The EMS provides automated control based on the established parameters.
• The EMS collects and stores data that can be used to identify energy savings opportunities.
• When energy-related issues arise, an alarm system within the EMS notifies a designated person or people. Issues can be resolved quickly, at minimal cost.
4. Use Energy-Saving Strategies
Energy usage reduction in retail space can be accomplished via many proven strategies. All of them can be easily applied to retail designs, operations, and upgrade projects and have documented successes to back-up their projected savings. The following are just a few of these strategies:
• scheduling and occupancy detection
• continuous commissioning
• daylight harvesting
• demand ventilation
• load shedding.
5. Measure Regularly
Energy usage data collection and analysis is a critical part of any successful energy cost reduction strategy. Collecting and analyzing data allows a retailer to:
• set a baseline based on normalized data.
• evaluate and prove the success of a strategy.
• recognize an abnormal situation.
A baseline — based on 12 months of energy usage data and square footage — identifies outliers, both positive and negative, across a portfolio of stores and allows retailers to target specific sites for energy usage reduction programs.
6. Know the Supply Side
• buying smart.
• verifying the accuracy of bills.
• ensuring that bills are paid on time.
7. Sustain the Effort
Energy management is not a one-time event. Programs that are not maintained quickly lose their energy cost savings. Retailers need to incorporate individual parts of their energy management program into their organization’s daily routine. For example, instead of designing and reviewing energy strategies for individual store designs, change the store design review process so that it includes a review of energy efficiency strategies.
