FINANCIAL STATEMENT: If the Council chooses to install additional lighting in the Council Chambers, the cost would be added to the City Cablecast Capital Improvement Project that will be completed in early Fiscal Year 2002-2003. It is estimated that the track lighting option would cost approximately $25,750 and the recessed lighting option would cost approximately $33,053. DESCRIPTION: At its meeting of November 20, 2001, the City Council approved a budget change to install mounted cameras and production equipment in the City Council Chambers. At the meeting, Staff noted that while adequate, the existing lighting did not allow for an optimal broadcast environment. The City Council agreed, and directed Staff to investigate options that would enhance the current lighting and provide lighting design options appropriate for a Council Chamber broadcast setting. Based on this direction, Staff hired Brian Kane and Associates (BRK) of Walnut Creek to provide the City with design options and cost estimates that would accomplish these goals° An initial assessment by BRK of the Council Chambers revealed that the vertical illuminance level at the Council dais and podium was between 12 and 18 foot candles (FC). Vertical lighting is what is shown on a person's face while sitting behind the dais or standing behind the podium. The existing ambient lighting provides better horizontal lighting, which is the lighting on a horizontal surface such as a table for reading. The recommended vertical illuminance level for this type of broadcast setting is approximately 75 FC. For comparison, the level for a television studio or theatrical setting is approximately 150 FC. COPIES TO: ITEM NO. ~ H/cc-for ms/agdastmt.doc Both lighting options provided by BRK produce approximately 60 FC. Combined with the existing lighting, the proposed lighting would raise the' vertical illuminance level to approximately 75 FC. The lighting would be controlled by programmable dimmers that would allow the lights to be returned to a pre-programmed level at the touch of a button. Track Lighting Ootion The first lighting option presented by BRK is track lighting affixed to the ceiling. The proposal is for 12 fixtures directed at the Council dais and a separate track with two fixtures directed at the public podium. The advantage of the track lighting is that it is a flexible, movable system that can be easily adjusted. The most obvious drawback of the system is the' aesthetics of the track and fixtures. While the fixtures would have a professional appearance, the lights would be very noticeable to both the Council and the public. The total cost of the track lighting, including installation is approximately $25,750. Attachment 1 shows · the cost estimate, track lighting specifications and placement on the ceiling. Recessed Fixture Option A second option for the Council to consider is recessed fixtures that would be inset in the ceiling. The number of lights and the illuminance level produced by the recessed fixtures would be identical to the track lighting. The primary advantage of the recessed fixtures is the aesthetics. The lighting would blend 'in with the existing lighting and Council Chamber d~cor and would not be as noticeable to the public. The disadvantage of this system is that it would be much more permanent and would allow less flexibility due to the modifications that would be made to the ceiling. The recessed fixtures would also cost approximately $33,053 or $7,303 more than the track lighting option. Attachment 2 shows the cost estimate, track lighting specifications and placement on the ceiling. RECOMMENDATION: Staff recommends that the Council first determine whether the City should install additional lighting in the City Council Chambers to improve meeting broadcasts. If the Council elects to install additional lighting, Staff requests that thc Council provide direction regarding the preferred lighting option (track lighting or recessed fixture).  ~ ~ ~ LIGHTING PLAN DUBLIN (TRACK FIXTURES) CIVIC CENTER LIGHTING ELEVATION PLAN CIVIC CENTER ParStar TM ,....,....,,,.,oo.
