Approval of the Minutes of the January 17, 2012 Meeting The minutes of the January 17, 2012 meeting were approved as written. II. City Facility Enhancement Projects (EECBG Funded) Presentation Stuart Kent, Executive Director, Public Works introduced Michelle Woytenko, Deputy Director, Public Works who presented this agenda item. In 2010, the City of Glendale received an Energy Efficiency and Conservation Block Grant in the amount of $2.32 million. The condition of the grant requires the City to use the funds in a cost-effective manner that creates jobs, reduces long-term energy use, reduces greenhouse gas emissions, and saves energy over the life of the project. Staff identified projects for the grant that emphasized savings in energy and maintenance, and improved safety. The distribution funds for this grant included $986,000 for Water Reclamation UV improvements, $173,000 for the Energy Matters Public Education Program, $107,000 Program Manager for EECBG Projects, $98,000 for Well 43 Variable Frequency Drive, $86,000 for Traffic Signal LED Conversion, $35,000 for a Building Safety Energy Program, and $840,000 for Facilities Lighting Retrofits, which is the focus of this presentation. Council Sustainability Committee May 15, 2012 Page 2 City Annual Electricity Costs Facilities Maintenance noticed an alarming trend that started in 2004-2005 where the cost for electricity in city buildings had substantially increased. The kilowatt-hour consumption was up, but not to the same volume as cost. From 2004 to 2008, the actual cost per kilowatt-hour increased from $0.06 to $0.10. To help manage the rising costs of electricity, Facilities Maintenance identified areas throughout the city where lighting upgrades were needed the most. This upgrade project would consist of replacing outdated and less energy efficient T-12 lamps with the more energy efficient T-8 lamps. Ninety-five percent of the energy that goes into a light is converted to heat, and five percent is actually used for lighting. With the T-12 lamps, the amount of heat emanating from these fixtures would be enough to cause an extra load to cool a building, raising cost and energy usage, so replacing these fixtures was a smart choice. As manufacturers began phasing out production of the T-12 lamps, local utility companies such as Arizona Public Service were offering incentives such as rebates to help offset the cost of the upgrade. Lighting Conversion Facilities Maintenance took it a step further by converting fixtures from one lamp to those with multiple lamps. Using multiple lamps not only enhances the quality of the lighting output, but it reduces the number of maintenance trips, which saves time and money. Sport Courts Facilities Maintenance looked at tennis, handball, and basketball courts with representatives from the Parks & Recreation, Code Enforcement, and the Police Department that had issues with either vandalism or graffiti. Eleven City parks, O'Neil, Rose Lane, Bonsall North, Mary Silva, Sonorita, Clavelito, Glendale High, Sands, Cholla, Acoma, and Chapparal received new lighting upgrades, representing 179 fixtures in all. This project has now been completed. The annual cost savings for the City was $12,472 in energy savings with 133,540-kilowatt hours of energy saved. The $16,050 Arizona Public Service Rebate that the City received will be turned back into energy saving projects. Main Library The Main Library was a large project where the entire lighting system was redesigned throughout the building. The savings on this project allowed for additional energy enhancements to be made where exterior lighting was installed and occupancy sensors were added inside the building. The $457,000 received for this project represents about half the funding for all the lighting conversion projects that were in the grant. Annual energy cost savings for this project was approximately $18,690 with 169,970-kilowatt hours of energy saved. Council Sustainability Committee May 15, 2012 Page 3 Public Safety Court Complex and Parking Garage The Public Safety Court Complex was initially planned to be just an interior project replacing ballasts and lamps, converting from the old T-12 technology to the new T-8 technology. The City saved about $30,000 in actual savings on the interior portion of the project with a rebate of approximately $22,080. Over 4500 bulbs in over 2000 fixtures were replaced for this project. With the significant amount of cost saving involved with this project, Facilities Maintenance submitted a request to the Department of Energy to add the parking garage to this project. This enhancement would reduce electrical usage and provide a safe, well-lit place to park. The energy savings on the parking garage portion of the project was somewhere around $5,000 per year with an $11,400 rebate. Equipment Management The Sports Court, Main Library, and the Public Safety Court Complex/Parking Garage represent what was initially proposed to complete the $840,000 grant. With additional funds remaining in the grant, it was decided to add Equipment Management to the list of projects. Equipment Management is responsible for the repair and maintenance of the City's vehicles. It provides fleet and equipment services out of a 70,000 square foot facility. There are 99 fixtures across the tire shop, heavy duty, light duty, and make ready areas. The facility was using a single bulb per fixture, and with the high ceilings, it required a lift to replace the light bulbs. This type of bulb is subject to early failure if the lights were continually turned on and off. As a result, the lights needed to stay on 24 hours a day. If this did not occur, it would result in more maintenance time. The facility is also evaporative cooled, so there was also a need to reduce the amount of heat generated inside the building during the summer months. The replacement of these fixtures reduces the amount of maintenance trips, and improves productivity. The systems estimated annual cost savings for this project was $12,152 with 180,252-kilowatt hours of energy saved. A rebate application for$14,850 was submitted for this project. Material Recovery Facility The Material Recovery Facility located at the Glendale Municipal Landfill site was another project added to the grant. The facility has 51 light fixtures. Issues with this facility again, were the single bulb. The lighting over the sorting conveyors presented several maintenance challenges, as the piles of incoming material had to be moved in order to change the light bulbs. The estimated annual energy savings for this project was $11,299 with 110,760-kilowatt hours of energy saved. There was no rebate associated with this project. Glendale Municipal Office Complex Parking Garage Another addition to this grant was the parking garage at the Glendale Municipal Office Complex. Since the replacement of 244 fixtures, the security issues have Council Sustainability Committee May 15, 2012 Page 4 gone away. This project yielded approximately $7,000 in annual cost savings along with a rebate that was submitted for $16,500. This project was contracted out which fit into nicely with the grant's goal of creating jobs in the community. Downtown Parking Garage The grant was also used to switch out 420 fixtures at the City's Downtown Parking Garage. Even though this is a newer facility, the technology is changing rapidly. The grant also helped to drive down the cost of materials. The annual cost savings for this project was estimated to be around $7,460 with 114,416-kilowatt hours of energy saved. The Arizona Public Service Rebate was submitted for $31,500.

The $99,073 in energy savings and $112,000 received in rebates will be used for this project. The initial proposal for this project included the four top parks, Sunset Ridge, Butler, Sunnyside, and Sunset Palms. Parks were selected based on copper theft concerns, maintenance requirements, cost to upgrade or replace, and vandalism. The City recently advertised an Invitation for Bid for solar lighting fixtures in four of the City's parks. The Initial bid was structured for four parks, but after evaluation and review of the bids, there is a possibility that Mission, Orangewood, Grand Canal, and Desert Garden Park could be included in the grant. Bids received on Friday, May 11, 2012 are currently being reviewed and a Notice of Intent to Award for this solicitation will be given to the most qualified and lowest responsive and responsible bidder. Council Sustainability Committee May 15, 2012 Page 5 EECBG Summary Approximately six weeks ago, the City met with the Department of Energy Project Manager for an annual monitoring visit. This was a successful meeting as Glendale met each goal associated with this grant. The Finance group who manages the grant allocations was commended for their records keeping and other aspects of the grant. The Department of Energy was very pleased with how the projects were selected and how the work was completed. The three most important goals of the grant, the creation of jobs, the reduction of greenhouse gases, and the reduction of energy consumption were successfully met. According to the Department of Energy, the projects created approximately 9.2 jobs for Glendale. It reduced greenhouse gases by almost 700 metric tons of carbon dioxide equivalent, which equates to taking 130 passenger vehicles off the road. The reduction in energy consumption was the equivalent to 83 homes. The money saved over the life of the project and reduced maintenance was projected at $99,000 annually in electricity costs. Several discussions took place during and after the presentation, none of which required any follow up or action on the part of staff. Vice-Mayor/ Chairperson Frate and Councilmember Knaack thanked staff for the presentation. As this was an informational item, no motion or vote was called for by the committee. III. Staff Updates Brad Tarrant, Energy Education Specialist reported that ASU's Sustainable Cities Network (SCN) was recognized nationally by being awarded the President's Award on April 18, 20112. In addition, Jo Miller who heads one of the SCN subcommittees was recognized by ASU for her participation and leadership in the Network. The Conservation and Sustainable Living program had two successful events recently.
