Description) Lighting Retrofit - City Hall Finance:e , _ � ' (�►�._ Council Notes: '7a_ngnq Annnfin Item Aln 141 CITY OF SAN BERN RDINO - REQUEST F R COUNCIL ACTION STAFF REPORT On June 6, 1992 , the Council authorized the Director of Public Works to develop plans and specifications to retrofit the lights in City Hall with more energy efficient light. The idea behind this retrofit project was to reduce the energy costs in this facility while maintaining adequate lighting levels. It was felt that this objective could be accomplished by replacing existing equipment with new energy efficient equipment, adding occupancy sensors, daylight overrides and other energy saving devices. A report was subsequently prepared by an outside energy consultant, Energy Controls and Concepts, dated 5-12-92 , at the request of the Facilities Management Division. The objective of this report was to investigate the lighting fixtures in City Hall and make recommendations on how they could be retrofitted to conserve energy. This report is attached. Major recommendations of this report include: RECOMMENDED MODIFICATIONS 1. Replace current 4 ft. fluorescent lamps with new T-8 fluorescent lamps. The new energy efficient lamps will provide the same foot candles for 20% less energy and life of the lamp will increase 20%. In several areas, such as storage, walkways, etc. lamps per fixture will be reduced from 4 to 2 lamps. 2 . Replace existing ballast with electronic ballasts. The electronic ballasts will reduce energy directly related to the ballast 30%. The largest savings will be related to the overall heat reduction that occurs when changing from standard ballast to electronic. The reduction in the heat will reduce the amount of cooling required and extend the life of the lamps. 3 . Replace existing incandescent/flood lamps with compact fluorescent lamps. The energy savings is 30% per fixture and the lamp life will increase 80%. 4 . The modifications also include adding occupancy sensors and daylight overrides in various locations.

This loan will be repaid in five (5) annual payments, beginning on 1-1-94 , plus simple interest at a rate of 4%. There is a sufficient balance in the Sewer Line Construction Fund to finance this loan, without deferring any budgeted sewer projects. We recommend that the loan be approved, in order to provide the necessary financing for this energy conservation project. 1 RESOLUTION NO. 2 RESOLUTION OF THE CITY OF SAN BERNARDINO AUTHORIZING A LOAN FROM THE SEWER LINE CONSTRUCTION FUND (245) TO ACCOUNT NO. 3 001-092-53666 - CITY HALL LIGHTING PROJECT, IN THE AMOUNT OF $187 , 000 TO FRONT THE COST TO BE INCURRED IN CONNECTION WITH THE 4 UPGRADE OF CITY HALL LIGHTING. 5 BE IT RESOLVED BY THE MAYOR AND COMMON COUNCIL OF THE CITY OF SAN BERNARDINO AS FOLLOWS: 6 SECTION 1 .

Sharp Project Manager Economic Development Agency Project: San Bernardino City Hall Building Address: 300 North "D" Street San Bernardino, CA 92418 Objectives: Update, modify and improve existing lighting equipment with new energy efficient replacements. Increase the lamp life and reduce electrical costs. Improve existing light levels as well as lamp life. Provide client a reasonable time frame for recapturing initial costs. Coordinate energy audits with the respective utility company in the area(s). Estimate utility rebates(if any) and cost savings. General Specifications: Includes energy efficient fluorescent lamps, electronic ballasts and controls in specified areas. Also includes compact fluorescent lamps in place of incandescents/floods and some replacement of diffusers. The following data was compiled using estimated burn times for all the various areas in this facility. You will note that burn times, lighting specifications and applications will vary in each area. In addition, please note that lamp wattage is computed based on lamp/ballast types in accordance with specifications provided by ANSI (the American National Standards Institute), the primary source by which electrical standards and measurements are assessed, and manufacturers' specifications. These assumptions are believed to be as close to accurate as can possibly be assessed based on our various sources of information that we deem reliable. Estimations in burn time were gathered from various sources at this facility. r Project Areas Description Area 1 6th Floor - Copy & Reception Area 2 6th Floor - Break Rooms Area 3 6th Floor - Administration, Conference & Storage Area 4 6th Floor - Sister City Showcase Area 5 6th Floor - City Attorney Area 6 6th Floor - City Attorney Area 7 6th Floor - Administration / Mayor/ Conference Area 8 6th Floor - Administration Halls Area 9 6th Floor - Mayor's Office Area 10 6th Floor - Mayor's Office Area 11 6th Floor - Conference Room / Mayor's Suite Area 12 5th Floor - Break Rooms Area 13 5th Floor- Water Department Aria 14 5th Floor - BP / Storage/ Copy/ Conference Area 15 5th Floor - Water Department Area 16 5th Floor - Water Department/ Circulation Area 17 5th Floor - Water Board Control Room Area 18 4th Floor- Occupational Health / Risk Management Area 19 4th Floor - Occupational Health/ Risk Management 20 4th Floor - OH Copy Room Ara: 21 4th Floor- Occupational Health / Risk Management Area ::2 4th Floor- Public Services Arez 23 4th Floor - Public Services/ Finance Area 24 4th Floor - Public Services/ Conference "A" & "B" / Break Room / Copy Area/ Filing Area 25 4th Floor - Finance / Break Room Area 26 4th Floor - Finance / Purchasing Area 27 4th Floor - Finance / Purchasing Area 28 4th Floor - Finance / Storage Area 29 3rd Floor - Planning / Public Works Area 30 3rd Fir pr - Planning / Public Works Area 31 3rd Finer - Smrags Rooms & Break Rooms Area 32 3rd Floor - Planning / Public Works Area 33 3rd Floor - Planning / Public Works-Storage Area 34 3rd Floor - Planning/ Circulation Area 35 2nd Floor - City Treasurer Area 36 2nd Floor - 0:ty Treasurer-Storage Area 37 2nd Floor - City Treasurer/ Storage/ Filing Rooms r Area 38 2nd Floor - City Clerk Area 39 2nd Floor - City Clerk-Storage Area 40 2nd Floor - Civil Service Area 41 2nd Floor - Civil Service-Storage Area 42 Mezzanine - Council Offices Area 43 Mezzanine - Council Offices Area 44 Mezzanine - Council Offices Area 45 Mezzanine - Conference Area 46 Mezzanine - Conference Area 47 1 st Floor - Lobby Area 48 1 st Floor - Council Chambers Area 49 1 st Floor - Council Chambers Area 50 1 st Floor - Council Chambers Area 51 1 st Floor - Council Chamber/ Audio Visual Area 52 1 st Floor - Council Chambers Area 53 1 st Floor - Council Chambers (Wall Washers) Area 54 Basement - EOC Area 55 Basement - B57/ Break Room / Mail Room Area 56 Basement - Central Services Area 57 Basement - Central Services/ Office Rooms Area 58 Basement - Central Services Area 59 Basement - MIS / Building Management Area 60 Basement - MIS / Building Management Area 61 Basement - MIS / Building Management Area 62 Penthouse - Mechanical Area 63 Penthouse - Mechanical Area 64 Stairwells Area 65 Common - Elevators Area 66 Common - Circulation Area 67 Common - Circulation Area 68 Common - Circulation Area 69 Common - Electrical Rooms Area 70 Common - Ditto Rooms/ Storage Area 71 Common - Restrooms Area 72 Common - Restrooms/ Janitorial Area 73 Common - Elevators Area 74 Common - Exit Signs Area 75 Opt. 1 Perimeter Luminaires / Ambient Light Sensing/ Continuous Dim Area 75 Opt. 2 Perimeter Luminaires/ IR Occupancy Sensing / Daylight Overri Area 1 i to Floor - Copy & Kecep:ion Specifications: 2* x 4' Drop-Ins/ 4 lamp/ F40CW/SS - 34 Watts Recommendations: Retrofit fixtures with HBF electronic ballasts and F032-4100ks Lamps.

In particular, the EPA estimates that for each kilowatt hour of energy saved there is an associated reduction in generation side pollution. The EPA has recently undertaken the task of retrofitting their own facilities in Washington D.C. with newer triphosphors lamps, specular reflectors and electronic ballasts. This newer technology has proven to result in tremendous savings with an even greater enhancement to the quality of fight in all environments. One very significant effect of an energy efficient lighting retrofit is that of emmission reductions.
