Item No.: 4d_Supp Date: April 14, 2015 Terminal 91 Lighting Upgrades & Controls Project Scope Replace 333 exterior lighting fixtures at Piers 90, 91 and cruise parking areas. Include lighting controls which will enable the Port to manage lighting effectively and further reduce energy use. 2 Project Objectives Reduce electrical consumption by over 721,000 kw/hrs per year. Reduce electricity costs by $40,000 or more annually. Defer 433 tons/yr GHG emissions Reduce maintenance cost by nearly $500,000 over 10 years Reduce light pollution and glare to neighborhoods. 3 T91 applications 4 Old Technology 381- 1000 watt High pressure sodium Fixtures; 333 identified for removal. Uses 4,380 kWh of electricity annually per fixture. Old HPS fixtures would cost the Port $90k annually (2015 energy rates) Requires re-lamping or ballast replacement every 3-5 years. 5 New Technology Will have replaced 333 old HPS fixtures with 308 LED and Plasma fixtures. New fixtures require 50% less energy to power them. With application of new controls we anticipate a net reduction of 73% in energy use which equates to a reduction of as much as 600,000 kWh in energy consumption. The anticipated annual energy costs are expected to be reduced from $90k to $24k based on current energy rates.

Limitations of Translatable Documents
PDF files are created with text and images are placed at an exact position on a page of a fixed size.
Web pages are fluid in nature, and the exact positioning of PDF text creates presentation problems.
PDFs that are full page graphics, or scanned pages are generally unable to be made accessible, In these cases, viewing whatever plain text could be extracted is the only alternative.
