Anchorage Square Parking Garage

When CB Richard Ellis (CBRE), one of the world’s largest commercial real estate management companies, took over operations of a 200,000 square foot parking garage in 2009, a lighting system upgrade was among its top priorities. Located in San Francisco’s popular Fisherman’s Wharf tourist destination, Anchorage Square garage has never had a problem attracting customers, but keeping energy costs in check was an ongoing issue. As a first step, the management team upgraded the lighting system to high efficiency T5HO fluorescent lamps in enclosed fixtures. With the lights on 24x7 and significant daylight available on the upper levels, a lighting control system was the obvious next step.

The CBRE team determined that traditional wired lighting controls would be costprohibitive while providing only limited functionality. Alternatively, the Adura Wireless Lighting Control System delivered a flexible and scalable platform, able to support the facility’s changing needs while providing an attractive financial payback.

Goals
CBRE’s criteria for selecting a lighting control retrofit solution required that the energy
savings should result in an investment payback within 3 years or less. A primary factor
in reaching this goal was controlling rewiring costs – in effect, necessitating a wireless
solution. After previous experiences with discrete lighting control components that
inconvenienced occupants, CBRE wanted a system that would enhance safety and
occupant comfort. Lastly, CBRE sought comprehensive data collection and real-time
energy monitoring capability, realizing that continuous operational improvement
requires accurate live reporting.

Application
Adura’s Wireless Lighting Control System with flexible control and energy management
features increased energy efficiency while providing powerful new management tools.
The primary control strategies deployed in this parking garage are daylight harvesting
and occupancy detection.

Results
The Adura Wireless Lighting Control System has exceeded all criteria for the Anchorage Square garage retrofit. Based on reported actual energy savings, the projected energy use on an annual basis will drop from 200,954kWh to just under 120,000kWh, a saving of just over 40%. This represents a projected direct energy-related savings close to $40,000.
