3 Challenge Ahead 1 In the next 25 years, energy cost and consumption will continue to increase. The cost of energy per kwh will increase to 11.8 cents as a national average, according to U.S. Energy Information Administration s Annual Energy Outlook 2015 Report. Commercial organizations that rely on high energy consuming refrigeration systems, such as food and beverage distributors, grocery store chains, dairy producers, pharmaceutical manufacturers. Commercial refrigeration standards are under discussion among stakeholders, and this will affect walk-in and reach-in coolers and freezers. Walk-in coolers and walk-in freezer panels, doors, and refrigeration systems are currently scheduled to comply with the updated standards begining in August Much of commercial refrigeration energy savings potential is associated with high efficiency fan motors and compressors.. - U.S. DOE Washington State has the lowest electricy rate at 7.15 cents 2015 Average U.S. retail price per Kwhr at 9.84 cents Expected % of increase by % Hawaii has the highest electricity cost at 34 cents Volume 1 Number 1

4 2 Use Case Client: Cold Beverage Distributor Facility Description: The facility had a refrigerator system that utilized 12 evaporators, comprising of 44 evaporator fans. 18 Avg Payback or Less (ROI) Annual Energy Consumption: 547,986 kwh (annually + not including defrost cycles) Solution: 44 single phase DC Electronically Commutated (EC) Motors + 12 Frigitek Controllers which communicate with the motors and compressors, and full system installation. $66K Annual estimated cost reduction when replacing standard motors with EC Motors and EC Controller on 12 Evaporators, with 44 Total Fans.

5 Gross Project Cost - $73, Incentive - $17,500 Net Project Cost - $55,863 Annual Estimated Cost Reduction - $66,903 Long-Term Savings With a payback under 24 months in many cases, the short and long-term savings of a project with HotWattEnergy will make you look like a super hero to your leadership. We will work with you to evaluate the best possible solution, energy incentives and project cost (financing options) for your business. We understand that you may have to sell the idea up the chain to your leadership team, which is why we create a very clear and concise proposal that will outline the overall gross project cost the energy incentive savings and the net cost of the project. Once we have calculated your project with our proven process, we can provide you with a real 2014 Volume 1 Number 1

6 4 The Benefit Power Reduction 80% Before using Frigitek EC Controllers with EC Motors, we can reduce your power consumption with less compressor run time. Average Pay Back Period 18/Mo Our goal is that on every project that our clients have one to two year payback or less The purpose of a commercial refrigeration compressor and related equiment is to remove the heat from the space. The fan motors often generate 30% of the overall heat from the refrigerated space. We utilize top of the line Frigitek EC Motors which typically reduce the heat load by as much as 75-80%. This is accomplished by lowering the voltage of the evaporator motors when the box is not being actively cooled. This results in a substantial reduction in annual operating cost. In addition to the cost reduced by the EC Motor replacement, HotWattEnergy can help further reduce your monthly energy cost by adding the Frigitek EC Controllers. Our goal is that on every project our clients have 1-2 yr payback or less. Soft and clean square brochure indesign template
