2 The Chiller Challenge - Market Outlook TARGETED SECTORS Universities & Campuses Hotels & Resorts Hospitals Data Centers Airports Transit Terminals Convention Centers Commercial Buildings Amusement Parks Whether a high rise office building, casino, hotel, convention center, hospital or almost any environmentally controlled building space with more than 200,000 square feet, chillers represent the most substantial and necessary facility cost. Using advanced technology, the EES Chiller-Drive Retrofit dramatically improves efficiency while decreasing its energy costs and environmental impact. YOUR OPPORTUNITY TO SAVE ON ENERGY COSTS For most building owners, chiller plant operations are an unavoidable requirement that represent a very high energy cost and carbon footprint liability. A major inefficiency with running a chiller is the all-on or all-off settings of the chiller motors. In fact, 95% of all centrifugal water cooled chillers run at less than 80% of full load, thus creating a substantial opportunity to save on energy costs and a reduction of related carbon emissions. IMPROVED PERFORMANCE An EES Chiller Retrofit enables existing chiller systems to improve performance which dramatically reduces energy costs and carbon emissions, while also contributing less mechanical stress and wear of the chiller. The EES Chiller Retrofit can be integrated into most chiller systems, regardless of the size, tonnage or voltage rating. It can even be applied to facilities with sensitive or critical electronics that require low electrical harmonics and may have tight space requirements. HARDWARE & SOFTWARE: A POWERFUL SOLUTION EES s Chiller-Drive Retrofit consists of both hardware and software elements working in unison to optimize the performance of your current chiller. The hardware employs advanced variable frequency drive technology that greatly reduces energy-related costs. With a well-established track record of functioning in difficult environments and exacting roles, quality variable frequency drives have been proven to enhance energy efficiency and reliability in HVAC applications. The proprietary EES software enables the retrofitted chiller to achieve maximum efficiency by adjusting its performance to meet exact system requirements, rather than simply turning it all-on or all-off. By adding a variable frequency drive (VFD) in combination with EES Interface technology, the retrofitted chillers are able to avoid a surge condition and dramatically reduce energy consumption. + + Centrifugal Chiller EES Optimization Interface Variable Frequency Drive 2

Thanks to the EES Chiller-Drive Retrofit, it s possible to dramatically reduce annual chiller costs conservatively up to 35 percent. Working together, hardware and software components minimize kilowatt usage and demand charges, while placing corporate climate and greenhouse gas sustainability goals within reach.

In fact, the EES Chiller-Drive Retrofit with a quality VFD added has been proven successful on chillers 20 to 30 years old with hermetically sealed motors. It is agnostic, compatible with virtually all high quality Variable Frequency Drives from the manufacturer of your choice. The EES Chiller-Drive Retrofit is a better solution, allowing customers to avoid the potential of overwhelming expenses associated with buying brand new chillers and their related equipment. SUSTAINABILITY With the EES Chiller-Drive Retrofit, facilities are able to reduce both their energy costs and their associated carbon footprint, thus contributing to a healthier environment. In doing so, many facilities may be able to qualify for a variety of local utility, state and federal financial incentives and rebates. Points towards higher LEED certification achievement will certainly be attained. The result is a true economic and environmental win/win that everyone can appreciate.

5 Exceptional Return On Investment OLD EQUIPMENT? NO PROBLEM. Age is no obstacle when it comes to an EES Chiller- Drive Optimization Retrofit. In fact, the older the system, (provided that proper maintenance has been followed), the more dramatic the energy cost savings you are likely to experience! CAN WE SAVE YOU MONEY? WITHOUT QUESTION: By adding a VFD and the EES interface to your chillers, you will experience the highest return on investment possible which in turn will easily save hundreds of thousands of dollars of energy costs per chiller annually. You can conservatively expect to save up to 35% of your current energy costs now being spent on running your chillers and create an exceptional return on your investment. Estimations of actual results will vary based on equipment, location, climate and general chiller plant design & maintenance. CUSTOM LEARNING ALGORITHMS Evolutionary Energy Solutions proprietary Chiller- Drive Retrofit directs your existing chiller to perform its many critical functions at optimal levels. Processed through our custom learning algorithms, this critical information is constantly being analyzed on a real-time basis to refine chiller system optimization. This in turn reduces chiller power demand to the highly efficient Variable Frequency Drive.

6 The Case Study: Paris Las Vegas Hotel & Casino Just wanted to follow up and let you know how well the Evolutionary Energy VFD solution installed last year on chiller #4, the 1750 ton York machine, at Paris Las Vegas is performing. Chiller 4 has become the lead chiller of the five we have at the Paris central chilled water plant due to its quiet, smooth and efficient operation. The VFD and its proprietary interface have exceeded projected energy savings by 30% leading to a payback of its investment of under two years - without including a sizable utility rebate which would bring it to just over a one year payback. Our chiller maintenance services provider, Johnson Controls, has inspected the drive prior to implementing a full service maintenance coverage agreement and has approved it and included it under their contract and have no issues with it affecting the chiller or its comprehensive service coverage. I would like to also mention that your staff is very knowledgeable and a pleasure to work with both during installation and afterwards.

7 A World Class Solution THE CHALLENGE The Paris Las Vegas Hotel & Casino is a 33-story building located in Las Vegas, Nevada. The property, owned and operated by the Caesar s Entertainment Corporation, was built in 1999, has 2,916 guest rooms and a convention center with over 115,121 square feet of convention space. Caesars Entertainment Corporation expressed its ongoing commitment to improving its corporate sustainability and reducing its carbon footprint from chiller plant operations per their CODE GREEN mandate. THE SOLUTION Evolutionary Energy Solutions specifically engineered a chiller retrofit plan for the Paris Hotel & Casino in Las Vegas. The EES Chiller VFD Optimization Interface was integrated with a Siemens GenIV 1250HP VFD on a single existing York 1500 Ton centrifugal chiller. Once the VFD was installed and commissioned, the EES Chiller VFD Optimization Interface was up and running within three days. The benefits and savings were dramatic and immediately realized by the chiller plant from day one of chiller operation. With our adaptive self-learning algorithms, the EES Chiller Optimization Interface self-adjusts to keep the chiller performing at its highest efficiency, while mitigating harmful surge conditions and providing optimized chiller startup capability. KILOWATT/TON PERFORMANCE The Paris Las Vegas Hotel & Casino is a proven ideal location experiencing a wide range of extreme year round load conditions, in turn, providing real world performance data for the EES Interface. During actual Summer full load conditions the chiller averaged 0.50kW/Ton and transitioned through the far more efficient part load periods of Spring and Fall to a very low average of 0.24kW/Ton in Winter. EES Interface & Monitor Installed THE ANNUALIZED IMPACT ON PARIS The Paris Las Vegas Hotel & Casino example of Evolutionary Energy Solutions Chiller VFD Optimization Interface is currently projected to provide the following benefits for this one chiller: Saving 3,695,200 kwh annually on chiller energy consumption Saving an average of $369,520 annually on chiller run costs Saving 25% from chiller baseline readings at full-load conditions Saving 30-50% from chiller baseline readings at part-load conditions Eliminating 2,809 tons of carbon emissions annually EVOLUTIONARY ENERGY SOLUTIONS IS READY TO ACHIEVE YOUR GOALS Phone or Fax: (866) Support@Evolutionary-Energy.com 7
