City Council Meeting ACTION:_. god.,1.s .ot-& Vr MOORPARK CITY COUNCIL AGENDA REPORT'_ fir — TO: Honorable City Council FROM: Jeremy Laurentowski, Landscape and Parks Manager DATE: July 8, 2011 (CC Meeting of July 20, 2011) SUBJECT: Consider Retrofitting the Existing Lighting at the Active Adult Center, Community Center, City Hall Administration Building, Development Services Building, Civic Center Parking Lot and Library Parking Lot; Award Contract to Sylvania Lighting Services Corporation and Authorize City Manager to Execute Agreement; and Resolution Amending the Fiscal Year 2011/12 Budget BACKGROUND In 2009, the City obtained an Energy Efficiency and Conservation Block Grant (EECBG), as a part of the American Recovery and Reinvestment Act (ARRA), in the amount of $148,600 for energy efficiency upgrades to the existing facilities Heating, Ventilation and Air Conditioning (HVAC) and Lighting Systems. During the June 16, 2010 City Council meeting, staff recommended two (2) phases to expend these grant monies which would yield the highest energy savings for the least amount of investment. Phase 1 included the replacement of seven (7) HVAC units that serve the Community Center and the Active Adult Center and was completed in December, 2010. Staff anticipates approximately 25% a year in direct energy savings due to the replacement of the HVAC units. Phase 2 included retrofitting the interior and exterior lighting of several City facilities. Staff has obtained an inventory and audit of all existing lighting systems at the City facilities and has solicited a fee proposal from Sylvania Lighting Services (Sylvania) to complete this work. DISCUSSION The City Council is being asked to approve retrofitting the existing lighting systems that serve the Active Adult Center, Community Center, City Hall Administration Building, the Development Services Building, Civic Center parking lot and the Library parking lot. According to the Lighting Upgrade Proposal and analysis prepared by Sylvania, retrofitting the existing lighting with new energy efficient lighting systems would result in substantial energy savings. In addition, it will help the City comply with current Title 24 lighting standards, the new Federal Minimum Energy Standards, reduce carbon emissions and reduce annual maintenance costs. SACommunity Services\ADMINISTRATIVE\CC Reports\2011\Facilities\City Hall\7-8-11 (Lighting Retrofit).doc 64 Honorable City Council July 20, 2011 Page 2 Staff is proposing to replace the interior and exterior lighting of several City facilities with a variety of energy efficient lighting upgrades. A major part of this project will include the change from traditional fluorescent T12 bulbs to low wattage fluorescent T8 bulbs. The fluorescent bulb identification terms, T'12' and T'8', refer to the diameter of the fluorescent tube in eighths of an inch. T12's are 12/8th of an inch, or 1 Y2" diameter, and T8's are 8/8th of an inch, or 1" in diameter. T12's use 40 watts of energy per bulb, as compared to 32 watts for each T8, ultimately reducing carbon emissions as the overall energy requirement at each facility will be reduced. Carbon is a byproduct of energy production. In addition, T8's have a life span of approximately 36,000 hours, compared to 20,000 hours for T12's, reducing overall product costs, maintenance costs and the staff time required to replace bulbs. However, staff has discovered that there are substantial challenges that exist with office lighting, specifically as it relates to lighting where employees are working on a computer, as well as referencing documents. According to the Illuminating Engineering Society of North America (IESNA), working at a computer requires light levels in the range of 10 footcandles, while referencing a document can require as much as 100 footcandles. In addition to varying light levels, individuals require different light levels based on distinct visual systems and comfort levels. In October, 2010, staff enlisted the services of Humanscale, a manufacturer of ergonomic office tools designed to solve functional problems in the workplace. Humanscale provided a lighting audit of the City Hall Administration Building. Their analysis confirms that most of the individual offices are currently too bright to comfortably work at a computer monitor, but not bright enough where employees need to reference documents. The light output within individual work stations and offices averaged between 27.1 and 36.4 footcandles. In addition, the Humanscale audit confirms that the common spaces and walkways between private offices and cubicles are over-illuminated. The Occupational Safety and Health Administration (OSHA) recommends light levels in the range of 30 footcandles for general use areas. Much of the common spaces in the Administration Building were illuminated between 50 and 61 footcandles. It has also been suggested that lower light levels increase productivity, alertness, comfort and may reduce headaches due to reduced eyestrain and frowning associated with ambient glare. In an effort to provide appropriate lighting levels, staff is recommending removing the existing four (4) lamp prismatic fixtures and replacing the fixtures with two (2) lamp fixtures with reflective lenses. Staff is confident that acceptable lighting levels will be obtained as the T8's emit higher lumens per bulb and loose only 10% of their initial brightness after approximately 7,000 hours of use, compared to T12's that loose approximately 20% over the same time frame. Staff is proposing to provide overhead task lighting to staff members that require increased illumination at their workspace. Staff is also proposing to replace the existing Metal Halide and High Pressure Sodium parking lot lights and exterior building lights with Light Emitting Diode (LED) lighting. LED lighting has a lifespan of approximately 50,000 hours with an estimated energy savings between 50% and 75% compared to traditional high wattage bulbs, such as Metal Halide and High Pressure Sodium. LED lighting has a high initial cost. However, 65 Honorable City Council July 20, 2011 Page 3 substantial savings in direct energy cost savings makes this product a viable solution for energy conservation. The Community Development Department will review any exterior lighting plans for glare reduction compliance. Staff has also obtained a proposal to retrofit the interior lighting of each City facility with LED lighting. However, the high initial cost due to the quantity of the fixtures and the relatively low wattage requirement of each facility makes LED interior lighting cost prohibitive. Staff has determined that the average cost recovery for interior LED lighting is between 15 and 20 years. LED interior lighting is also a relatively new product and several lighting professionals have cautioned staff on moving forward with these products at this time. As mentioned previously, most manufacturers claim that LED lighting has a 50,000 hour lifespan. These products have not been in production long enough to substantiate 15 years of performance.

The 2010 RFP and contract (Contract No. 6293) superseded an earlier RFP and contract developed in 2004. The "heart" of the RFP is a unit pricing schedule listing a large number of commonly performed lighting efficiency tasks. These tasks include everything from simple retrofits of existing fluorescent fixtures, to new technology replacement fixtures. The successful bidder committed themselves to the specific unit price for the life of the contract, with a stipulated annual cost-of-living adjustment. The unit price included all labor and materials associated with completing the task in each unit price description. All labor costs are based on Federal and State prevailing wage requirements. In the 2004, and the subsequent 2010 RFP, provisions were made for other public agencies to utilize the competitively bid RFP for their own lighting projects. Each city or other public agency could reference and "piggyback" the County's bidding process and solicit proposals from the County's contracted vendor, without having to repeat the bidding process. The contractor (Sylvania) must adhere to the same pricing as defined in the County contract. Piggybacking is a practice accepted in the California Public Contract Code, as long as it can be demonstrated that: 1. The work being undertaken is clearly consistent with the work defined in the original RFP. 2. The RFP is of recent origin (interpreted by most agencies as three (3) years or less). 3. The pricing is consistent with the original RFP. The 2010 RFP clearly requires the successful bidder to make unit pricing available to any public agency that chooses to piggyback on the agreement. The following is a list of public agencies that have taken advantage of the piggyback options of the 2004 and 2010 lighting services agreement: • City of Ventura • City of Oxnard • Ojai Unified School District • Ventura County Office of Education • Gold Coast Transit District • City of Thousand Oaks • Conejo Park and Recreation District • City of Santa Paula • City of Fillmore • City of Port Hueneme • City of Ojai 68 Honorable City Council July 20, 2011 Page 6 The current contract has a term from January, 2011 to January, 2013, with three 1-year extensions, if mutually agreed upon by the County and Sylvania. Staff recommends `piggybacking' the County of Ventura Request for Proposals No. 5554, for Lighting Efficiency Services, Issued September 09, 2010, and Contract No. 6293 between the County of Ventura and Sylvania Lighting Services Corporation, entered on January 20, 2011. FISCAL IMPACT The City of Moorpark obtained $148,600 from the EECBG in 2009. Phase I, which included the replacement of seven (7) HVAC units, was completed in 2010 at a total cost of $76,746. $71,854 is available for the proposed lighting retrofit project. A cost summary follows: Cost Summary: Energy Efficiency and Conservation Block Grant (EECBG) 148,600 Phase I (HVAC replacement project 2010) 76,746 EECBG Remaining Balance 71,854 Active Adult Center 9,350 Community Center 15,245 City Hall Administration Building 41,851 Development Services Building 13,637 Library 12,445 Project Investment 92,528 (35) task lights @ $150 ea. 5,250 10% Contingency 9,778 Sub-total Project Investment 107,556 EECBG Remaining Balance (71,854) Total Project Investment 35,702 Total Estimated SCE Rebates (11,268) Total Net Project Investment 24,434 The total project cost was excluded from the fiscal year 2011/12 spending plan and a budget amendment of $107,556 is required in the Facilities Division (7620). $71,854 will be appropriated from the Other State/Federal Grant Fund (2609), the $13,690 from the Library Services Fund (1010) and the remaining $22,012 will come from the General Fund (1000). Staff anticipates $11,268 in Southern California Edison (SCE) rebates to partially offset this initial investment. 69 Honorable City Council July 20, 2011 Page 7 STAFF RECOMMENDATION (ROLL CALL VOTE) 1.

Specifically,we were to evaluate the lighting levels at each workstation as well as general office areas to identify opportunities to decrease energy usage while increasing employee comfort and productivity. There are challenges that exist with office lighting, specifically as it relates to lighting where employees are working on a computer as well as referencing documents. As supported by the Illuminating Engineering Society of North America (IESNA),working at a computer requires light levels in the range of 10 footcandles,while referencing a document can require as much as 100 footcandles. In addition to those varying light levels, people require different light levels based on their individual visual systems. Findings: There are significant opportunities to decrease energy usage in two areas. First are the private offices. All of the offices, as documented below, are too bright to comfortably work on a computer monitor and not bright enough where the employees reference documents. At full power, or three illuminated 32 watt bulbs,the average footcandles on the computer were 27.1. Average footcandles on the documents where employees work were at 36.4. You can decrease the energy usage in these private offices by using two bulbs rather than three and adding adjustable task lights. With two bulbs illuminated the average light levels at the computer drop to 24.6 and drop to 28.8 at the documents. When you add an adjustable task light,you can keep the 24.6 footcandles at the monitor and increase the light levels at the document by an additional 100 footcandles. This decrease in overhead lighting can represent up to a 33.3%decrease in the energy used by the fixture,going from 3 bulbs at 32 watts to 2 bulbs at 32 watts. Further savings can be realized by decreasing the wattage from 32 watt bulbs to 25 watt bulbs. The second area of opportunity to save on energy usage is in the general office area,which includes walkways as well as cubicles. Generally speaking,this area is significantly over-illuminated in some areas and under-illuminated in others. The over-illuminated areas include the walkway between the private offices and the row of cubicle walls. OSHA recommends light levels of approximately 30 footcandles for general office areas. Much of the space is illuminated to 50 footcandles,with one area as high as 61 footcandles. There are two different fixtures in the drop-down ceiling of the general office space. Some of the fixtures have three 32 watt bulbs and some have four 32 watt bulbs. 90 The city of Moorpark may be able to decrease their overall energy usage by removing the center bulb in the fixtures with three bulbs, and the two middle bulbs in the fixtures with four bulbs. Doing so will not only decrease the energy usage, but will cut down on costs to purchase new bulbs as well as shrink the maintenance costs associated with replacing bulbs. However, if the City of Moorpark decreases the amount of light from the overhead fixtures,they will need to increase the level of light on employee workstations by providing adjustable task lights which enable an employee to put the light on their documents when they need to illuminate the documents. Financial impact: Decreasing the energy usage in the building will have a positive financial impact on the City of Moorpark. While there will be a one-time cost associated with purchasing adjustable task lights,the cost of the task light investment will be recouped over time. Annual financial savings from decreasing energy usage(assumes removing 132 watt bulb in three bulb fixtures and 2 32 watt bulbs in four bulb fixtures): $2,141.60. There is a one-time cost associated with purchasing adjustable task lights. When selecting any task light, a specific criterion should be followed to ensure that the light works the way an employee needs it to work. Failure to follow a criteria will likely lead to selecting a light that does not work as required, and will cause the employee to be forced to read documents without the proper level of illumination. The following criteria should be applied to all task lights that are being evaluated: 1. Able to adjust the position of the light with one hand. This needs to be accomplished without the light falling over. 2. Remain cool to the touch. If a light gives off too much heat, it causes a safety and comfort problem. 3. Needs to have a large enough footprint of light that allows it to illuminate the documents without having to constantly move the light. 4. Provide a neutral white light temperature. According to IESNA,this temperature is 3500 Kelvin. 5. Use only one light source or bulb. This is specific to LED lights. Any LED task light needs to illuminate the documents using only one light source as opposed to multiple light sources. 6. Be sustainable, in terms of energy usage, life span, and recyclability. The one-time cost for the adjustable task lights may be approximately$3,000.00 Recommendations: 1. Remove the center bulb from the fixtures which use three bulbs. 91 2. Remove the two middle bulbs from the fixtures which use four bulbs. I Provide adjustable task lighting to the employees who work on computers and reference documents. Ensure that the criterion set above is followed when selecting an adjustable task light. 92
