Maximizing energy savings and system performance
Maximizing energy savings and system performance
Because refrigeration & HVAC systems already consume a significant amount of energy (more than half of a supermarket's energy use), inefficient systems dramatically increase these operational costs even more. With years of field-based experience and numerous proprietary and proven processes, our highly-trained Energy Optimization (EO) team performs in-depth energy audits, surveys and retro-commissioning tailored to your specific system. These expert technicians specialize in analyzing, assessing and recommending cost-saving adjustments to ensure the most reliable and efficient performance of your entire refrigeration or HVAC system, including your Energy Management Systems (EMS).
And unlike most EO service providers, Source has the expertise and resources to execute any recommended adjustments, and provide any required follow-up service, repairs or maintenance for the sustainability of your optimized system. This "one-stop-shop" capability ensures that all recommended cost-saving adjustments are executed accurately and seamlessly.
In addition to minimizing energy consumption, a properly set and balanced system reduces compressor and contactor cycling, thus reducing wear and tear and equipment downtime. The result is improved shopping or operating conditions and lower maintenance costs.

Retro-commissioning is a systematic process applied to building systems to identify and implement operational improvements that help ensure their continued performance over time while saving significant energy costs. The retro-commissioning process most often focuses on dynamic, high-cost energy-using systems like refrigeration & HVAC, with the goal of reducing energy waste, obtaining energy cost savings, and identifying and fixing existing problems.
Retro-commissioning also helps ensure system functionality. It is an inclusive and systematic process that intends not only to optimize how equipment and systems operate, but also to optimize how systems function together. Although retro-commissioning may include recommendations for capital improvements, the primary focus is on using tune-up activities and diagnostic testing to optimize the building systems both from a performance and cost perspective. Retro-commissioning is not a substitute for major repair work, and repairing major problems is a must before retro-commissioning can be fully completed and effective.
At Source, our Energy Optimization Team is expert at retro-commissioning refrigeration & HVAC EMS systems to yield significant energy savings and performance improvements for our customers.
The primary objectives of our retro-commissioning programs for refrigeration & HVAC systems are:
One of the most effective ways to manage energy consumption in a grocery store or industrial facility is to install an Energy Management System (EMS). An EMS is the foundation of any retailer's energy and maintenance reduction strategy. Today's leading EMSs are designed to provide complete control of building and refrigeration systems including: compressor groups, condensers, walk-ins, HVAC units and lighting. In addition to monitoring and reducing energy usage across equipment types in the store, EMS also provide for a gradual, automated starting-up and stopping of energy usage at the beginning and end of a stores operating hours. These systems also control energy usage to avoid spikes in demand that are costly for both a retailer and the broader energy grid.
Benefits of an EMS are as follows:
Installing an EMS system is only half of the equation. Once installed the system needs to be optimized for maximum and sustained effectiveness. Our Energy Optimization team is expertly trained and experienced at installing and/or retrofitting EMS and optimizing new and existing systems. And because we are vendor neutral, we are trained and certified to install and optimize EMS systems from all leading manufacturers.
According to the U.S. Department of Energy, motor-driven equipment accounts for 64 percent of the electricity consumed by U.S. industry. As businesses come under increasing pressure to reduce energy use and operating costs, the installation or retrofit of variable-speed drives (VFDs) are emerging as a popular solution. VFDs reduce electrical energy consumption by adjusting a motor's speed to match the required load. Many electric motors simply do not need to run at 100-percent capacity all of the time — such as those that power Condensers and Air Handler motors in grocery stores. By retrofitting these motors with VFDs, grocery stores and other facilities can control the equipment's output to match the operation's needs, saving energy when full output is not required, and with no impact to a system's operation.
With advances in microelectronics and control technology over the past 10-15 years, VFDs have become an efficient and reliable means of controlling motor speed. Facilities that install VFDs will:
Source's Energy Optimization team is ready to work with you to install VFDs where appropriate and execute this simple but effective energy saving solution!
Unfortunately, there are times when a refrigeration or HVAC system needs more than simple maintenance. We all know the signs: a spike in energy use, an increase in refrigerant use or evidence of a leak, more frequent refrigeration failures and/or loss of refrigerated product, or an increase in maintenance costs. If you have any of these issues, your Refrigeration System has a problem. Source can help.
At Source, we have the knowledge, skills, processes and equipment to diagnose problems and recommend solutions for problem/high-cost systems.

Installing new refrigeration or HVAC systems or executing major remodels are significant investments. At Source, we highly recommend to our customers that they have all new systems "commissioned" to ensure that 1) they were properly installed per the customer's engineering drawings and 2) they are operating effectively and efficiently from the start. We think the cost of commissioning is a small price to pay as an insurance policy and for peace of mind.
Executed by our dedicated team of Energy Optimization specialists, our commissioning process is third party validation that a new or remodeled system is installed properly and operating efficiently. The deliverables of our program are:
Managing humidity levels has long been a challenge for grocery stores and other businesses where customer comfort or product integrity depends on proper internal climate. This is especially true in high-humidity climates. The common practice of adjusting a building's air temperature to try to maintain an acceptable humidity level dramatically increases energy use and costs, and can negatively affect customer comfort. Additionally, too much humidity can cause condensation on the refrigerator coils, further increasing energy usage. In a grocery retail setting, frost and ice can form on case doors and the product itself, leading to product deterioration and an undesirable appearance.
The most reliable and cost-effective way to manage the humidity challenge is to install a dehumidification system through a retrofit or remodel or as part of the initial system installation on new construction projects. Not only will a dehumidification system help manage your humidity levels for an improved customer experience and an enhanced worker environment, this valuable investment has been shown to save grocery stores and other businesses tens of thousands of dollars a year in energy savings and operating costs.
Source Refrigeration & HVAC is an expert service provider for mission-critical Refrigeration & HVAC systems, which includes dehumidification. We are trained on all major dehumidification technologies and with all major dehumidification equipment manufacturers.

Lighting in grocery stores represents about 13% of the electricity consumption, not including the impact on cooling loads. Lighting retrofits to LED lights can save 30 to 60 percent on lighting energy as well as 10 to 20 percent of cooling energy when compared to traditional, fluorescent lighting.
In addition to energy savings, today's LED lighting plays an important role in creating an inviting shopping experience and increasing sales through better product illumination. Advances in LED lighting technology now offer grocery stores an option to fluorescent lighting that produces better lighting, especially in refrigerated display cases because LED lights perform very well in cold temperatures. In fact, research has shown that customers find LED lighting in freezers to be "brighter, more even, more appealing and more comfortable." Packaging and food colors are brighter and more attractive to shippers. Additionally, LED Tube lights will only need to be replaced once every 10 years reducing maintenance and recycling costs.
Whether part of a new design, a remodel or a Door Retrofit program, the Source team has the experience to assist you in the selection and installation of LED lighting that is best for your store.
