The intent of this PFA is to complete a comprehensive energy development study of the identified buildings, as shown in the table below. Syserco’s technical team collects and analyzes faci lity data, conducts onsite analysis of the building enve lope, mechanical, electrical, controls, lighting an d water system to build a recommended list of Energy Conser vation Measures (ECMs). Building Area Police Operations 15,000 Los Gatos Civic Center 38,000 Los Gatos Public Library 29,000 LGS Recreation - Youth Center 6,479 LGS Recreation - Adult Center 12,000 Los Gatos Corporation Yard 15,479 The intent of this report is to provide a high leve l understanding of implementation costs and energy and water savings implications of the recommended Energ y Conservation Measures (ECMs). On the basis of these projections, Syserco Energy Solutions feels c onfident that further investigation is warranted an d would ultimately result in improvement to occupant comfort and reductions in energy consumption, maintenance and operational costs for the sites. Team Effort Syserco would like to thank of the Town of Los Gato s staff and facilities personnel who worked closely with our team throughout this process. Without the contr ibutions and assistance from Jim Harbin – Facilities & Environmental Programs Manager , Jeremiah George – Facility Lead and occupants of the buildings , this report would not have been possible without their s upport and input. Approach Syserco Energy Solutions assists customers with dev eloping innovative solutions to maximize capital to address existing infrastructure needs through energ y savings. The PFA process involved site visits, cu rrent utility consumption analysis and Q&A with facility staff. The goal of the PFA is to identify areas to improve reliability, increase efficiency, reduce operating costs and create healthy physical environments for the building occupants. The integrated and performance based Design-Construct-Optimize-Support energy services method has been shown to provide a significant amount of value to our customers. By accepting responsibility and effectively managing risks for the project, Syserco can provide customers with the option of a number of project structures, from GMAX to Lump Sum pricing. Our turn key Energy Services offerings include: · Energy and Utility Analysis · Developing master plan for ECMs across portfolios · Comprehensive energy management services · Project development, design and construction · Competitive pricing from subcontractors Town of Los Gatos Preliminary Facility Assessment July 2017 Proprietary and Confidential Page 4 · Construction cost and utility savings development · Building systems commissioning where applicable · Project financing where applicable · Operations staff training and development · Utility Monitoring and Verification reporting · Develop project with safety as top priority Procurement Process Moving from the PFA through the IGA phase of develo pment and ultimately entering into a construction contract, typically entails officially procuring Sy serco Energy Solutions as the energy efficiency pro vider for the customer. This can be done through the Best Val ue Contracting process (CA code 4127.1) or a typica l RFQ process. Syserco has experience doing both kind s of procurement with success. Best Value contracting per CA Government Code Secti on 4217.1 was created by the state over 37 years ag o to encourage energy efficiency within existing publ ic facilities by allowing public agencies the abili ty to utilize the ensuing energy savings as an alternativ e funding source to finance infrastructure upgrades that were deemed a net benefit and cost effective. Sect ion 4217 provides local agencies great flexibility to use the contracting method that the governing body dete rmines to be in the best interest of the agency. Government Code Section 4217 authorizes local gover nments to enter into energy contracts on terms that are found to be “in the best interests” of the agen cy, “notwithstanding any other provision of law. I n essence, Section 4217 allows a public agency to sel ect a qualified Energy Services contractor to desig n and deliver energy efficiency projects so long as the a nticipated cost for the energy project or efficienc y services are less than the anticipated energy cost savings t o be derived from those services. This code is comm only used by Energy Services Companies that pursue perfo rmance-based contracts with public agencies to provide cost and savings visibility and transparenc y while minimizing risk on ongoing system performan ce. A significant advantage of utilizing an integrated and turnkey Energy Services Contract via 4217 is th at the Town of Los Gatos has a single contract and point o f accountability for both the design and implementa tion of the Energy Conservation project. The contract is fully inclusive of all services and products to be delivered by Syserco Energy Solutio ns. We will work collaboratively with the Town through the design and development process, while demonstratin g a thorough and detailed knowledge of the project re quirements, so that we are able to deliver this pro ject in the most efficient, transparent, cost-effective, and predictable manner as possible. The process for utilizing “Best Value” contracting to implement an Energy Savings Project is shown in the following flow chart.

Baseline Utility Analysis Introduction The basis of this Preliminary Facility Analysis is the energy baseline of the sites. By understanding the energy usage of electric and natural gas utilities and how that energy is consumed in the buildings, it is po ssible to identify the most effective areas to improve the ef ficiency of the buildings. Each building is separat ely metered for electricity and natural gas. This secti on will look at the consumption of each of the util ities separately and then the dollar consumption for each utility, the utility rates and how that informatio n interacts with the environment and weather and how the buildings compare to similar buildings in California. Syserco Energy Solutions reviewed utili ty data for the identified buildings which includes electricity and natural gas consumption and costs. The period over which utility data was analyzed is calendar year 2012 to 2017. The base year for the report is 2016. Electricity Analysis Electricity is the primary energy source consumed i n the Town of Los Gatos buildings. Electrical data for 2012 to 2017 was analyzed for the six buildings ide ntified in this PFA. The most complete utility year was 2016 and is the baseline for the PFA. These buildin gs consume an annual average of 1,618,497 kWh/yr fo r the past three years. The information received was complete for the last three years. The Town purchas es the electricity from PG&E. The following table show s the electrical consumption for the buildings over the last three years. In addition to the PG&E electric service at the bui ldings, there are a number of solar PV systems inst alled across the Town. The Library, Police Operations and Corporate Yard have solar PV systems installed to aid in production of electricity for the sites. The Lib rary system was installed with the construction of the building and is owned by the town directly. The Pol ice and Corporate Yard solar PV systems are part of a solar Power Purchase Agreement (PPA). Specifics aro und the production and contracts were not received as part of the PFA study. However, any benefits rea lized by a greater energy project would increase th e amount of solar production consumed at the site to the benefit of the town. As part of the IGA an in d epth analysis would be completed on the solar PV systems and how best to utilize them as part of the energy and cost portfolio.

In California a study is compiled on a regular basis that looks at all of the buildings in the state along with their electrical and gas energy us e and the end use systems of that energy. This is t hen compiled in to a large report called the California Commercial End-use Survey or CEUS for short. The k ey metrics that are looked at within this report is th e Energy Use Index (EUI) and Energy Cost Index (ECI ). The different major categories can be compared to a spe cific building to determine how efficient or ineffi cient a building is relative to its peers. The following pie charts show what a typical electrical use consu mption looks like for small office buildings and miscellan eous buildings.

ECM Recommendations Introduction The following Energy Conservation Measure (ECM) rec ommendations have been assembled based on an initial energy site walk through the buildings. The se ECMs vary in scope, magnitude, complexity and re turn on investment. Syserco Energy Solutions will assist in the development, scope definition, implementati on, commissioning and ongoing support for the selected ECMs. The ECMs identified in this section are preliminari ly divided into two groups: Priority 1 and Priority 2. Priority 1 is what Syserco Energy Solutions recomme nds to implement now as they will have a significan t impact on the buildings as well as their financial viability. Priority 2 measures will require signifi cant additional investigation, bring minimal savings or high costs to the project but could solve a specifi c problem within the buildings. Regardless of classification in this report all ECMs will be investigated, along with any additional measures identified during additional as sessment, in the Investment Grade Audit. The intent of this section is to present an initial project scope that works well to improve the energ y efficiency of the buildings as well as improve the comfort of the buildings while being constructible. Unless specifically stated otherwise, Syserco Energy Solut ions believes that each of these ECMs hold promise individually, but collectively provide a significan t positive benefit to the Town of Los Gatos. These proposed ECM’s provide additional benefits in cluding, but not limited to: · Energy and utility cost savings generated through E CM’s, after any debt service, which will be a benefit for years to come · Help mitigate capital improvement needs · Improve occupant comfort within the buildings · Help to further protect the environment · Reduce their carbon footprint The following descriptions go into the details abou t each ECM at a high level. Each ECM will have a description of the measure, the reason for recommen dation, anticipated simple payback and potential EC M benefits. Town of Los Gatos Preliminary Facility Assessment July 2017 Proprietary and Confidential Page 42 ECM Priority 1 Recommendations ECM 1.01 – Comprehensive BMS Upgrade Description of Measure The intent of this measure is to update the BMS in the Civic Center by removing the existing Trane Tra cer Summit BMS controllers and front end and implement a new Alerton system. This would include replacement of the global controllers, front end co mputer, programming and system components identified in a detailed survey. Recommendations Syserco recommends implementing the new BMS control system which includes the review and tune up of the sequence of operations, set points, setbacks, o utside air temperature reset strategies, scheduling , economizer optimization, central plant optimization strategies and implementation of trending and alar ms. The new system would have a similar functionality, but would be user friendly and intuitive to use. Th is measure will interact with all other controls measu res as well as a number of other ECMs and would be very beneficial to the successful implementation of the identified measures. Anticipated Simple Payback Short Payback (0 -7 Years) Medium Payback (8 -15 Years) Long Payback (15+ Years) Low Cost ($0 -$50k) Medium Cost ($50k -$150k) High Cost ($150k+ ECM Benefits Comfort Improvement Utility Savings Safety / Code Compliance Reliability / Extended Equip Life Operational / Maintenance Savings Future Feature Compatibility Town of Los Gatos Preliminary Facility Assessment July 2017 Proprietary and Confidential Page 43 ECM 1.02 – Install BMS Fault Detection Diagnostics An alytics Tool Description of Measure By installing a new comprehensive BMS system in the Civic Center to control the building is the first step in optimizing the building energy use. The next step i s to provide the facility staff and operators a pow erful tool with which to identify, prioritize and track t he buildings needs and performance over time. Fault Detection Diagnostics (FDD) tools are the implement ation of this strategy. Recommendations Syserco recommends installation of FDD tools to the BMS in order to reduce the time to identify mechan ical and controls issues resulting in energy, cost and o perational savings. By receiving timely updates whi ch are prioritized by cost, time, impact, etc the faciliti es personnel can be assured that their time is spen t focusing on the highest impact repairs and preventative main tenance items rather than responding to hot/cold ca lls from occupants.

This system is standalone and d ifficult to use according to the facility operators. The int ent of this measure will be to remove the existing Tracer Summit equipment and install new Alerton global con trollers and other applicable equipment to provide a complete turnkey installation. Recommendations This measure will be integrated with the BMS propos ed for the Civic building allowing the facilities personnel to view and monitor both building systems remotely reducing trouble shooting time. Having an integrated BMS across the major buildings will prov ide better maintainability of the buildings. Since the building is new and there is a comprehensive BMS al ready in place, this is a long payback item but a p riority for the facility personnel. Typically, this would n ot be a recommendation to move forward since the sa vings and return on investment would not be financially c ompelling.

As part of other proposed me asures to replace control valves and modify air han dling equipment a balancing of the building is part of in dustry best practices. Recommendations Syserco recommends that a comprehensive air and wat er balance be performed at the Civic Center and a water balance at the Adult Recreation Center. When a significant number of control valves, fans and pu mps are improved as part of a project, it is in the own er’s interest to ensure that the systems are proper ly balanced to ensure that flows are appropriate and h elp improve the building operation, not make it mor e complicated.

Air filters typically are replaced every 3-6 months in good preventative maintenance p rograms. Typical air filters introduce a high stati c pressure on the fan quickly in the filter life. By utilizing high efficiency air filter as part of the SOP regarding air filters, energy, time, inventory and waste can be reduced while maintaining a superior air quality . Recommendations Syserco recommends to utilize high efficiency air f ilters in all air handling equipment in order to re duce energy use to move air, reduce frequency of air fil ter changes, improve air quality and reduce invento ry and waste from the buildings. Anticipated Simple Payback Short Payback (0 -7 Years) Medium Payback (8 -15 Years) Long Payb ack (15+ Years) Low Cost ($0 -$50k) Medium Cost ($50k -$150k) High Cost ($150k+ ECM Benefits Comfort Improvement Utility Savings Safety / Code Compliance Reliability / Extended Equip Life Operational / Maintenance Savings Future Feature Compatibility Town of Los Gatos Preliminary Facility Assessment July 2017 Proprietary and Confidential Page 50 ECM 2.03 – Internal Coil Protection Description of Measure All refrigeration systems degrade in performance ov er time. Per ASHRAE, new equipment can degrade up to 7% in the first year, up to 5% in years 2 and 3 and up to 2% for every operational year thereafter. This degradation is significant to the operational costs for the equipment. Not only will the equipment continually require additional input energy to get the same cooling effect, the maintenance of the equipment will go up over time with greater wear an d tear. Recommendations Syserco recommends installation of Permafrost produ ct to fully commissioned and tuned up refrigeration systems to improve efficiency. This is a PERMANT so lution that is intended to be a final step in impro ving operational efficiency of refrigeration equipment i n good working order. This will help to reduce oil migration from the compressor sump to the evaporato r coils, improving heat transfer of the coils and reducing the kW/ton energy rating of the unit.

The control valves are in fair to poor shape and ma y have a substantial amount of failed equipment. Th is measure will replace all control valves with new va lves to ensure proper functionality. This will bene fit from ECM 2.01. Facility personnel stated that the buildi ng is very difficult to maintain temperature in on a year round basis. The heating season is specifically cha llenging and the building runs 24/7 to keep the chi ll off the building. Recommendations Syserco recommends replacement of old control valve s as they tend to fail when they are significantly past their useful life. When they fail they will either fail open, resulting in significant energy waste by allowing water to flow through the coil constantly and consu ming significant amounts of pump energy. They can also fail closed or partially closed which forces t he fan in the unit to run constantly to try and mee t demand. In both cases significant amounts of energy are was ted in order to a modicum of comfort.

This is an effe ctive way to transfer power. Typical belts used are smooth be lts in up to 4 belts for a single fan. Smooth belts are inefficient in power transfer compared to cogged be lts. The smooth belts result in heat buildup in the belt material, increased bending pressure on the materia l, bulging of the belt around pulleys and poor heat transfer. Cogged V belts improve all of these chara cteristics of power transfer and result in ~3% savi ngs of energy transfer. Recommendations Syserco recommends installation of new cogged V bel ts on all equipment and modifying the SOP for maintenance to only purchase cogged belts in the fu ture.

The control valves modulate the flow of water through the coils based on demand from the space. Most control valves receive all commands fro m the BMS system and have limited to no on board logic. Belimo Energy Valves have a built in flow se nsor, supply and return temperature probe and contr ol valve which is used to control the flow of water th rough the coils. This configuration is a BTU meter and control valve in a single package with a significan t amount of onboard computing and storage capabilit y. These valves can operate in the absence of BMS sing les if need be. Utilization of energy valves give t he building operator a significant amount of control o ver occupant comfort and energy savings and the abi lity to slide between the two extremes dynamically and a utomatically. Recommendations Syserco recommends installation of energy valves on all AHU coils to provide the optimal flow through the coils to result in the most efficient use of hot an d chilled water. This measure realizes a full maint enance cycle on all CVs and provides significant advantage s to building control.

This is inefficient when equipment is cycling on and off over the day which results in significa nt waste of HHW or CHW generation which is bypassing through 3 way CVs to be pumped around again. By converting any 3 way CVs to 2 way and installing VF Ds on the pump motors significant energy savings ca n be realized. Recommendations Installation of VFDs on pumps is an industry best p ractice and will help to reduce the energy use for the building. With the 3 way CVs removed from the syste m the pump will have the ability to modulate based on demand and save energy based on the pump affinit y laws.

Lighting te chnology is constantly improving both the efficienc y of the lamps and ballasts themselves, as well as the contr ols of the lighting systems. This measure would per form a comprehensive lighting audit of all buildings, in terior and exterior, and provide recommendations to improve the light quality, reduce energy use and br ing the lighting system up to compliance with Title 24. Recommendations This is a good measure considering the age of the b uildings and their lighting systems. The only build ing that would not see significant benefit from a light ing audit would be the Library building.

These gaps allow significant air infi ltration and exfiltration. Essentially all the conditioned a ir generated for the comfort of the interior is imp acted negatively by the influence of outside air mixing i n and causing changes to temperature and in some ca ses causing drafts. Additionally, these gaps can allow water and pest infiltration which can be not only detrimental to the energy use of the building, but finishes and structure of the building.

Thi s plug load is typically an unknown quantity and therefor unmanageable. By working closely with the IT Director it is possible to greatly improve the computer efficiency, IT distributions and updates w ith minimal oversite. By reducing the time that computers, printers and monitors are left on or in low power mode energy can be saved across a large number of offices in a very short period of time.

The Corporate Yard has three air compressors used for s hop use that were noted during the site walk. Nearl y every shop has an air compressor that has a number of quick connects and at least one dust blower to c lean debris from work spaces. There are more efficient e lectric tools available to do the same functions wi thout the need to have an air compressor operating 24/7. Recommendations Syserco recommends replacing existing air tools wit h electrically driven equivalents. Process equipmen t that utilizes compressed air should have smaller pu rpose supplied air with as few connections as possi ble. Any air leak that can be heard in a quiet room is c osting at least $800/yr in electricity. Ideally, tu rning off the air compressor entirely is the most effective s olution.

The system appears to be fully functional and collecting data on all s ystems. However, due to the cost of the metering da ta analysis the Town has stopped paying the subscripti on fee. As a result the data is being collected and possible exported to Powersmiths servers but not be ing reported back to the Town BMS for actionable us e. This measure will integrate the existing Cyberhawk submetering system to the existing BMS for actionab le use by the Town. Recommendations Syserco advocates to collect and analyze as much in formation about buildings as possible to understand building operations and improve efficiency. This me asure could be challenging to get the data ported o ut to the new recommended Alerton BMS system. This is a good measure to integrate as much of the data as possible, especially since the infrastructure is in place.

There are currently no submeters on these make up water l ines to measure how much water is being used. These submeters could potentially be used to apply for a sewer credit on the water bill. More investigation into the water and sewer billing structure and incentive s would need to be investigated to determine if thi s is possible. Recommendations With a comprehensive submeter system already instal led in the building, this is a minor addition to th e system to ensure all the utilities are metered for accurate analysis. The potential to utilize a sewer credit on this water may be a viable way to pay for the su bmeters and provide additional future cost reductio ns on operations.

The lighting system has occupancy sensors which turn the lights off to save energy but the RTUs continue to operate mostly 24/7. This results in significant RTU run hours when they could be reduced to more accurately reflect the occupancy of the building. Recommendations By integrating lighting controls to RTU controls to reduce run hours for the whole building, not just one system. With the erratic building operation hours s ome additional logic may be required to ensure that the systems are properly coordinated without adverse im pact to the occupants. With additional investigatio n this could be successfully implemented to the RTU c ontrols.

Facility personnel have indicated that th is unit is shut down during the winter due to over cooling the space and not being able to heat the air suffic iently. The occupants would rather have the buildin g run warm than cool and this poses a problem. As a resul t the individual space FCUs operate 24/7 when the building is cold in order to keep some level of hea t in the building, wasting heating and fan energy w hen the MAU could do the job more efficiently. Recommendations This measure will need some more investigation to u nderstand how the MAU operates and determine the issues with the equipment and control valves. It is possible that a whole unit replacement is not need ed and just a major tune up. However, it is unclear at this point and will need be done.

The main issue is th at the chiller short cycles and never really shuts down fo r long periods of time, even overnight. This equipm ent is in fair condition and with improved BMS controls an d more advanced control valves and control strategi es. There are two options, replacement in kind with ano ther water cooled chiller which could be right size d. The alternate is to replace the chiller and cooling tower with a new air cooled chiller. Recommendations This measure will require significant development e ffort to understand if it is even needed and what t he optimal solution would be.

The split DX syste ms are in fair to poor condition and nearing the en d of their useful life. By replacing these units with ne w high efficiency heat pumps significant amount of energy used to cool the server rooms. Recommendations By improving the efficiency of the equipment form D X cooling to air cooled heat pumps, the building wi ll be much more efficient. It is possible, and even li kely, that new refrigerant line sets will need to b e run as part of this measure in order to install the new eq uipment.

Next Steps After analyzing the building data and information g athered as part of the initial site walk for the To wn of Los Gatos buildings, our technical review team has noted areas of opportunity to reduce utility consumption, improve building infrastructure and im prove occupant comfort. This report is the culmination of understanding about the current faci lity operations and the energy focused recommendations for improvements. Given the existin g building utility usage and corresponding carbon emissions the identified ECMs are worth investigati ng to improve the building operations. Based on the facility goals to reduce energy consum ption and maintenance operations as laid out by the facility operators, Syserco Energy Solutions propos es to proceed with the next phase of the project cy cle. The next phase is the commencement and completion o f the Investment Grade Audit (IGA) for the identified buildings. The Investment Grade Audit is a directed engineerin g study that provides the owners with detailed proj ect scoping, developed engineering savings calculations and budgeted costs for implementation and estimate d utility rebates and incentives as well as proposed project financing alternatives. The result of the I GA is a vendor neutral engineered solution that provides al l details required for a successful project aimed a t reducing the energy consumption of the buildings. Key Objectives · Verify gross square footage of facilities · Verify all utility accounts and meters · Evaluate high demand electric usage · Complete energy performance benchmark · Installation of temporary data and power loggers wh ere applicable · Evaluation of BMS trends where possible · Functional performance tests where needed · Perform detailed energy engineering savings calcula tions on recommended ECMs · Develop detailed SOW and budgeted construction cost s for recommended ECMs · Work with owner to develop financial funding altern atives where possible · Provide final IGA report to gain key stake holder a cceptance for approval Syserco Energy Solutions looks forward to helping t he Town of Los Gatos facility operations department with the development and implementation of prioriti zed ECMs at these six buildings identified in this report.
