That Tender No. T -2 -2014 submitted by Canadian Tech Air Systems Inc. in the amount of $217,864.00 (HST included) be accepted; 3. That the total gross project cost of $308,038.00 (HST included), including the amount of the tender and other associated costs, and the total net project cost of $277,398.00 (net of HST rebate), be approved; 4. That Council authorize the Division Head, Finance & Treasurer to finance the project as provided for in the 2013 Recreation Complex - Core Capital Budget in the amount of $277,398.00 from the Federal Gas Tax Reserve Fund; and 5. That -the appropriate City of Pickering officials be authorized to take necessary action to give effect hereto. Executive Summary: The existing chiller. that provides cooling for the Pickering Recreation Complex has reached the end of its economic life cycle. Installing an energy efficient back up chiller will reduce the energy demands on the existing chiller which will result in less annual maintenance costs and significant energy savings while still meeting the cooling demands of the facility. Staff have determined that the most cost - efficient solution is to install a chiller with a Magnetic Bearing Centrifugal Chiller complete with variable frequency drive (VFD) and Floating Head Control. To that end, Tender No. T- 2L2014 was prepared and advertised on the City's website. The low bid submitted by Canadian Tech Air Systems Inc. in the amount of $217,864.00 (HST included) is recommended for approval. The total gross project cost is estimated to be $308,038.00 and the total net project cost is estimated at $277,398.00 (net of HST rebate).

Unfortunately, the existing chiller that provides cooling for the Pickering Recreation Complex has reached the end of its economic life cycle. In addition to the declining condition of the existing chiller, it is also of an older and inefficient design with an annual electricity consumption of 209,836 kWh or annual r'• Report CR 11 -14 June 9, 2014 Subject: Tender for Back Up Chiller for Pickering Recreation Complex Page 3 electricity costs of $28,184.00. The chiller has been identified for upgrade with the intention of replacing it with a lower capacity A/C chiller to provide improved efficiency at nominal air conditioning loads. I.B. Storey Professional Energy Solutions were retained by the City of Pickering to complete a study and make recommendations for the most cost effective and energy efficient replacement chiller. I.B. Storey issued their final report entitled Pickering Recreation Complex; Comparative Analysis Briefing Report dated December 3, 2013. In that report, a Magnetic Bearing Centrifugal Chiller complete with VFD and Floating Head Control was identified as the recommended option that met all of the criteria of the study. The recommended equipment will provide reduced annual maintenance cost and annual electricity cost savings in the order of $13,000.00. Chillers typically operate at 80% full load or higher.for less than 5% of the year. Part load efficiency is the largest contributing factor to cost savings. The VFD increases the chiller efficiency significantly during times of part loading. The Magnetic Bearing reduces maintenance as the unit does not require oil for lubrication or cooling.

Storey Inc.'s approach is to evaluate the primary replacement options according to a common matrix, which will promote an unbiased recommendation. Three options are evaluated in this report, the estimated energy and demand savings are presented, along with estimated project implementation costs. ANALYSIS In order to properly determine the best replacement option, the projected energy usage was determined. The estimated energy usage for the existing A/C chiller is shown below: ExistingCliiller • Peak Electrical Demand 120 kW Annual Electricity Consumption 209,836 kWh Annual Electricity Cost $28,184 While on site it was noted that the existing chiller is oversized .for the current facility cooling loads. A maximum cooling load of 200 TR was determined based on a cooling analysis of the facility and discussions with the facility staff on the operation of the existing chiller during peak days. The A/C. chiller has been slated for replacement with a smaller, more efficient chiller for the intended operation. 1. B. Storey Inc. CONFIDENTIAL & PROPRIETARY Pmfesaronat Energy Solurrons. Version 1.0 - PAGE 2 of 4 299 PICKERIIYG RECREATION COMPLEX CotiIPARATIVEANALYSIS BRIEFING COMPONENT SELECTIONS Air Conditioning ChitlerSeteetion 1 Nrtes�eos�&olgiaos The existing chiller has been identified for upgrade as part of this project with the intention of replacing it with a lower capacity A/C chiller to provide improved efficiency at nominal air conditioning loads. The current unit is oversized even for peak design days and operates at inefficient operating points during average conditions. A centrifugal chiller with VFD is a conventional option to replace the existing unit. While centrifugal compressors are a conventional option, the .efficiency is lower than more modern, innovative machines. A centrifugal chiller is prone to surging at high and low pressures. Surging can cause severe vibrations that may damage the compressor. The maintenance costs associated with a centrifugal chiller are comparable to the rotary screw compressor. The second upgrade recommendation is to replace the oversized rotary screw compressor with a reduced capacity rotary screw compressor equipped with a VFD, A reduced size A/C chiller will operate at a higher capacity than a larger unit resulting iri increased efficiencies throughout the year, Rotary screw compressors are more efficient at full capacity then at trim capacity due to the slide valve capacity control. During times of part loading, the new unit would be equipped with a VFD to provide more efficient. capacity control. A magnetic bearing centrifugal chiller is an attractive option to replace the existing chiller, Magnetic bearing chillers have significantly reduced maintenance costs — as the unit does not require oil for lubrication or cooling. This reduces the amount of components, simplifying the design and increasing the reliability compared to oil based designs. The magnetic bearings also reduce the vibration of the unit, improving the overall life, This compressor type also provides substantial efficiency improvements over conventional units, as shown above. The highest part loading efficiencies can be obtained by the magnetic bearing centrifugal chillers. 1 Maintenance costs compared to existing unit. 2 Nominal efficiency is the average operating efficiency. 3 Cost comparison based on lowest cost option..

To keep you ahead of the curve, Johnson Controls has developed numerous technological innovations for our YORK° chillers. When some refrigerants were identified as ozone depleters, we adapted our chillers to use compounds that are friendly to the environment. When electricity prices began to escalate, we developed enhanced tubes and'variable- speed drives that slashed energy use. And when the industry was looking for ways to recover energy, we developed a full line of heat - recovery chillers. To help you meet today's challenges, Johnson Controls designed the YORK YVWA chiller. This cutting -edge design uses a number of engineering advances to address four primary requirements of building owners and designers— efficiency, application flexibility, sustainability, and confidence.

By making variable -speed technology standard on every YORK YVWA chiller, Johnson Controls delivers high energy performance and low ownership cost. The base model YVWA chiller is more efficient than most competitive chillers. There is a simple reason for this phenomenon. In most places in the world, the variable -speed YVWA chiller saves energy during 99% of operating hours spent at off - design conditions, which include reduced load and /or reduced entering condenser- water temperature. In addition, you can specify that your YVWA chiller be built with optimized performance, which can deliver an Integrated Part Load Value (IPLV) that is as much as 30% better than ordinary chillers. e YVWA chiller makes it easy :ost and ownership cost.

One chiller. Like all screw chillers, the YVWA chiller is capable of handling higher pressure lift than a centrifugal chiller. As a result, a thermal- storage application that requires glycol to be chilled to 14oF, or a heat recovery or heat -pump application that requires water to be heated to 150 °F, are within the capabilities of the YVWA chiller. However, unlike ordinary screw chillers, the YVWA chiller has the flexibility to handle these high -lift applications with. the highest efficiencies available. The difference is its variable -speed drive which constantly tunes the compressor speed to the exact lift and load requirements. The remarkable flexibility offered by the variable - speed technology also allows the YVWA chiller to utilize a wide range of heat - rejection methods: in addition to an open cooling tower, you can also use a closed- circuit cooling tower, a dry cooler, or an adiabatic cooler, all with the peace of mind that the YVWA chiller is giving you the highest efficiency possible. The YVWA chiller can efficiently handle the low evaporator. pressure required for ice thermal storage. (Photo courtesy of Baltimore Air Coil) The YVWA can be used in heat -pump applications producing hot water for high - volume users such as hospitals and hotels. Reach greener goals. Start with a smaller footprint. Why should you pay an economic penalty for being environmentally friendly? Unlike competitive chillers, the YVWA chiller does not make you choose between saving money and saving the environment. The YVWA chiller reduces environmental impact in two ways: directly, by managing refrigerant charges and the potential refrigerant leak points; and indirectly, by minimizing power -plant CO2 emissions, which are responsible for 98% of the Global Warming Potential associated with chillers. To reduce the direct effect, the YVWA chiller uses HFC -134a refrigerant, which has no ozone - depletion potential and no phase -out date. We also reduced the number of fitting, joints, and other potential leak points by 35% compared to conventional compressor designs. Plus,,our proprietary falling -film evaporator design allows refrigerant charge to be reduced by as much as 30% compared.to conventional designs. The indirect effect is addressed through the superior energy performance of the YVWA chiller, which cuts the energy that the power plant needs to produce and reduces emissions by as much as 30 %. Finally, the YVWA chiller makes it easy for you to earn points in the LEED° green - building certification program. Reduce direct emissions with the YVWA's falling -film evaporator, which reduces refrigerant charges by up to 30 %. (Photo courtesy of the LTCM lob of the Ecole Polytechnique Federole de Lausanne, Switzerland) The efficiency of the YVWA chiller can reduce your environmental footprint. Less electricity has to be generated, which means greenhouse -gas emissions created by the power plant are reduced by as much as 30 %.

ECWT ( °F / °C) YORK YK chillers can utilize ECWTs as low as 55 °F (13 °C) to reach 0.20 kW /ton (18 COP) at off - design conditions, reducing instantaneous energy consumption by as much as 50 %. The capacity range of the YORK model YK chiller is 250 to 3,000 TR (880 to 10,540 M). Both low- voltage (250 to 575 V) and medium - voltage (2,300 to 13.800 V) designs are available. Real -world energy performance is essential YORK© model YK centrifugal chillers, manufactured by Johnson Controls, provide the'best route to real - world energy performance - the combined performance at all operating conditions, not just design. Because chillers in the real world operate nearly 99% of the time at off - design conditions, off - design performance is the major factor in energy consumption. That's why YK centrifugal chillers are engineered for maximum efficiency at both design and off - design conditions. Unsurpassed Integrated Part Load Value The Air - conditioning, Heating, and Refrigeration Institute (AHRI) Chiller Certification Program endorses the validity of off - design analysis to compare chiller energy consumption. Measured with AHRI's Integrated Part Load Value (IPLV), YK centrifugal chillers are unsurpassed in energy efficiency. Equipped with an OptiSpeed- variable -speed drive, they can reduce energy usage as low as 0.20 kW /TR at off - design conditions. Adaptive capacity control optimizes performance When a YORK YK chiller-is equipped with an OptiSpeed drive, it incorporates advanced Adaptive Capacity Control logic, which continually optimizes chiller operation. It closely examines critical operating parameters, and then determines the most efficient way to operate. In addition, it lets you optimize your savings when using intelligent control strategies, such as chilled -water reset. Adaptive Capacity Control logic also accommodates the characteristics of the refrigerant used in the chiller- today and tomorrow. 317 Take advantage of colder eritering- condenser water Unlike competitive chillers which require entering condenser -water temperature (ECWT) from the cooling tower to be held artificially high, YORK YK centrifugal chillers can utilize ECWT as low as 55 °F (13 0C). The lower ECWT reduces the compressor workload, and that can reduce instantaneous energy consumption as much as 50 %. Powerful control center saves energy YK chillers feature the OptiViewd' Control Center, which -uses microprocessor capabilities to save you energy. Operation at just 10 below the designed chilled - water- temperature setpoint can increase chiller energy consumption by as much' as 3 %, wasting thousands of kilowatt -hours and dollars each year. The digital precision of the OptiView Control Center lets you set chilled -water temperature to a resolution of ± 0.1 °. As a result, you eliminate the energy wasted by drifting a degree or more from the setpoint. The OptiView Control Center can also be used to schedule daily operating hours and holidays. No longer is energy accidentally wasted cooling the facility when it's not needed. 318 The OptiView Control Center helps you operate your YORK YK chiller more efficiently by allowing for the precise setting of chilled-water temperature and operating schedule. Maximum.control with OptiView' Control. Center Easy to operate The intuitive, full -color OptiView Control Center offers you a higher level of monitoring and control. Data input is foolproof, and data outputs are shown in association with illustrations of the appropriate chiller components. For convenience, all data can be displayed in eleven different languages, in addition to Imperial or SI units. Easy to monitor The OptiView Control Center allows on -board trending of up to six different values, selected from over 100 variables. The values and sampling interval are all user - selectable. This flexibility allows you to select parameters that are critical for your operation and to perform trending without a BAS interface and separate monitor. Easy to integrate Energy savings and ease -of -use can be fully realized when the HVAC system is an integrated part of the building- automation system. The OptiView Control Center is designed to communicate with the Johnson Controls Metasys© system. It can also communicate with most control systems on the market today using its optional Kink communication card. Data outputs on the OptiView Control Center are accompanied with an illustration of the appropriate chiller component, making chiller operation more intuitive. The trending screen provided performance insights not possible with snap shot observations. 319 Versatile design provides superior sustainability and flexibility Environmental responsibility The environmental impact of your chiller can be significant. You can reduce your impact by specifying YORK YK chillers. You'll get the benefit of refrigerant HFC -134a, which has zero ozone depletion potential (ODP). Plus, the high efficiency of the chillers reduces the indirect global warming potential (GWP), which is 98% of the total impact, caused by greenhouse -gas emissions produced by your utility to power the chiller. In addition, because of the chillers' high efficiency, your building could earn points for the Optimize Energy Performance (EAc1) credit in the Leadership in Energy and Environmental Design° (LEED) program. Falling -film technology, utilized in the evaporator of YK chillers, reduces the refrigerant charge by up to 40 %. It is available in YK chillers up to about 1,000 TR (based on conditions), and will help your building to qualify for maximum LEED points for Enhanced . Refrigerant Management (EAc4). Reduced noise levels Traditional centrifugal chillers can generate a substantial amount of objectionable noise, but the YORK YK chiller is equipped with the innovative OptiSound'°" Control, which reduces noise at off - design conditions. The control continuously monitors the characteristics of the compressor - discharge gas and optimizes the diffuser spacing of the compressor to minimize noisy gas -flow disruptions from the impeller. Chiller operation is also stabilized. Flexible heating option The YORK YK chiller can also be configured as a heat - recovery chiller, for use in facilities with simultaneous heating and,cooling requirements. The heat - recovery unit takes advantage of the free heat that is typically rejected by the cooling towers. The heat can be used tb control humidity, reheat the air, and preheat domestic hot water. Heat - recovery units have - outstanding heating coefficients of performance that can reach up to 11.4. 320 Ouick restart and return to setpoint The Quick Start feature available on the YORK YK chiller reduces the risks that temperature- sensitive facilities experience after a power interruption. YK chillers equipped with this feature restart and return to the specified chilled -water temperature faster, reducing the risks of expensive downtime. A falling -film evaporator is more efficient because refrigerant is sprayed over the tubes, reducing refrigerant charge up to 40 %. a 3 a Q J V � J � o� T C u o o The YK chiller is available in a heat - recovery configuration. Recovered heat can be used in the HVAC or domestic hot -water systems. Maximum reliability with minimum maintenance OptiView Control Center keeps you well- informed The OptiView Control Center provides complete information on your chiller's operating condition. Safety- shutdown information includes day, time, cause of shutdown and type of restart required. Color- coding of fault messages allows easy determination of chiller status. Yellow messages signify shutdowns with automatic restart, requiring no operator intervention. Red messages are displayed for shutdowns requiring manual restart, alerting the operator that a system check may be required. The Trending Screen can show changes in motor current, oil temperature and pressure, refrigerant pressures, or water temperatures, all of which can be valuable indicators of developing problems. This capability gives you ample time to take corrective measures before any expensive downtime is incurred. With the OptiView Control Center, you can see when to schedule routine maintenance in advance of actual need. Open drive is easy to maintain The YORK YK centrifugal chiller uses an open -motor driveline, which means less downtime. If a motor failure occurs, the chiller can be brought back online much faster and at a reduced cost. The motor is easy to remove, and can be repaired at a local motor shop. As a result, downtime due to motor failure is dramatically reduced. Printed on recycled paper. PUBL -5187 (1010) Supercedes PUBL -5187 (908) © 2010 Johnson Controls, Inc. P.O. Box 423, Milwaukee, WI 53201 Printed in USA www.johnsoncontrols.com Electrical protection extends motor life Equipped with an OptiSpeed drive, the YK chiller starts "softly," never letting the inrush current exceed 100% of the full -load amps. By limiting the inrush, the motor windings do not rub together with expansion, which results in longer motor life and less chiller downtime. Lower inrush also reduces torque stresses on the motor and compressor driveline.
