Proven Results – Case Study Shows Significant Equipment Energy Savings

By | Case Studies, Efficiency, Energy Management | No Comments

Real Data. Real Results.

Every day we get asked, ‘How can we be certain we are saving energy and money?”  The truth is we monitor your equipment daily. We take action if we see a warning or get an alarm. More so, we look at the details of the equipment and if a something is running too long, or too short we take action to notify you.  Equipment runtime is provided in quarterly reports and compared across your entire portfolio. See Portfolio Post.

Occasionally, customers ask for a pre-metering phase so they can understand the baseline metrics of each store. This is a bit more expensive, but it does help you understand the amount of energy your critical equipment is using and how much money we will save you.  We never pre-meter your entire portfolio, but we will pre-meter up to three stores.

I wanted to share with you a recent pre-metering case study because it is homogenous to most of the portfolios using Small Box Energy’s chameleon™.  The estimated ROI for this portfolio ranged from 30-49% depending on the location and equipment used – after the managed service fee.

Below are metrics from three stores. This is real data; we just omitted the name.

Overall Energy Savings

All three stores experienced overall energy savings based on the pre and post meter data. Overall savings were achieved by reducing refrigeration defrost cycles and automating HVAC and lighting schedules.

Store 1 Savings

Overall, the largest reduction in energy consumption from this site comes from their refrigeration equipment. By eliminating unnecessary defrost cycles, our chameleon adaptable controller reduces energy, eliminates ice formation and maintains a steady inside temperature.

Store 2 Savings

For this site, the largest improvement was for the HVAC equipment. In most cases, we find employees override the system and forgot to set the temperatures back. With chameleon, the system is locked with limited override capability. This ensures comfort and conserves energy.

Store 3 Savings

This site also saw a large reduction in refrigeration energy use. However; not all equipment improved. For Store 3, we had to move the room sensors. While this increased the comfort, it also increased the run-time for the unit. Room balance and sensor placement will always dictate the run-time for the HVAC unit. Many times we find moving the sensors improves efficiency, where in this situation it did not.

Achieving Energy Star Advantages Everyday

By | Efficiency, Energy Management | No Comments

Why wait to do routine energy and equipment audits when chameleon™ provides it 24/7.

Energy Star recommends 5 practical things for increasing profitability by making improvements to your building.

Step1: Retrocommissioning –Identify underperforming equipment, determine which equipment should be replaced, and review operational tips to improve building performance.

Step 2: Lighting – Improve your lighting systems to reduce lighting energy use, improve the visual environment, and affect the sizing of HVAC and electrical systems.

Step 3: Supplemental Load Reductions –Improve heating, cooling, and electric loads in your building to reduce the size and cost of equipment upgrades.

Step 4: Air Distribution Systems – Upgrade or adjust your fan systems to maximize energy efficiency.

Step 5: Heating and Cooling Systems – After implementing the steps above, you may be ready to upgrade to a new, properly sized system, or to retrofit your existing system to optimize operation, reduce noise, and reduce the amount of required maintenance.

chameleon webDid you know Small Box Energy gives you the tools and data to achieve all these requirements, every day? In fact, these are part of our goals.  

Retrocommissioning – 24/7 data allows you to easily find underperforming equipment through graphical analysis, as well as urgent and warning alarms. Small Box Energy’s chameleon platform provides continuous commissioning meaning your system settings will never be left off target.

Lighting Controls – Controlling and scheduling lighting is instrumental in keeping lights off during non-operating hours and exterior lights off during daylight hours. We can also add motion-based sensors for maximum efficiency in less used areas.

Supplemental Load Reductions – Being able to review run-times and how often your equipment reaches the target room temperature gives you the data necessary to see if your equipment is sized accurately for your demand, or if it just needs maintenance. Because of the details our system provides, customers have identified a number of small improvements to reduce energy and load on the equipment including window shades and temperature set-point adjustments. And if anything starts to go off track, our alarms and alerts let you know immediately.

Air Distribution Systems – Our interface shows the status of the equipment at all times. Sometimes, the room isn’t balanced, sometimes the duct work isn’t correct for the configuration of the room, or sometimes users believe fans need to be running for ventilation. Use the data to make the adjustments and you will save money.

Heating/Cooling and Refrigeration Systems – Having the data for your entire portfolio helps you become more strategic with your cash flow when determining when to replace or upgrade your current equipment. Our chameleon controllers also optimize runtimes, maintain food quality and extend the life of existing equipment.

Small Box Energy is more than an energy management solution for today; we are your operational efficiency partner well poised to support your business every day for years to come.  All this data is available to you 24/7, so you are always maximizing equipment efficiency with early equipment diagnostics when repairs or replacements are needed.

What’s stopping you from getting started with us? Call your sales representative and let’s talk through your concerns. We have many customers saving money and seeing the value of early equipment diagnostics, temperature monitoring, and remote portfolio management and we want you to achieve these same great results!

Equipment Performance – A Portfolio Perspective

By | Early Equipment Diagnostics, Efficiency, Energy Management, IoT | No Comments

Quarterly reports review your entire portfolio highlighting run-times, energy usage, and alarms.

Whether you own 2 stores or 200, being efficient is the key to reducing operating costs. Small Box Energy understands that need, which is why we provide quarterly ‘Fit’ reports specifically for your equipment.

You’ll be able to see and compare:

  • HVAC compressor runtimes
  • Walk-in compressor runtimes
  • Alarms over the period
  • HVAC target temperature overrides
  • Energy Usage

A sample report looks like the picture below.

Data Enables Strategic Decision Making

One of the advantages of IoT is the ability to access data. In fact, we serve up over 140,000 data points each day for each of our sites that we monitor. But what do you do with it? How do you analyze it? What is the real advantage of having all this data? The advantage isn’t the data, the advantage is having the tools to combine and display the data you need into a useful format that is easy to read and understand. As the picture depicts above, we segregate and display the data by equipment so you can easily read and compare. Colors indicate performance evaluations. You can quickly scan the data, pick out the equipment in danger and compare the data across your entire portfolio. Customers have been able to make strategic decisions for efficiency, such as these:

  • Modify temperature settings to maximize energy efficiency
  • Choose to repair or replace equipment based on performance and other portfolio equipment needs
  • Evaluate a 3rd party vendor
  • Eliminate or modify existing preventative maintenance program based on equipment needs
  • Reevaluate the design and equipment needs for new locations

IoT and data provide the means, Small Box Energy makes it useful and actionable. Call us today or request a presentation.
