2RW responsibilities included:

• Project management
• On-site lighting energy audits
• Creation of lighting upgrade strategies and scopes of work
• Quantification of energy and dollar savings
• Detailed design and preparation of contract documents to obtain fixed prices from contractors
• Construction administration
• Lighting systems and controls commissioning
• Pre- and post-construction electrical monitoring to quantify actual savings
• Development of as-built record drawings

Due to the tight schedules imposed by the ARRA program, the first phase of the project – lighting audits, savings calculations, and conceptual design development – was completed in 45 calendar days. To meet this aggressive schedule, 2rw fielded five field crews to survey eight buildings (federal courthouses, federal office buildings and associated parking structures) with a total floor area of over 2.5 million square feet at five locations throughout GSA Region 4.

Based on the first phase results, 2RW engineers assisted with the final design of lighting upgrades at five buildings. Among the innovative strategies used to reduce lighting energy use were:

• Volumetric luminaires
• Spectrally Enhanced Lighting
• T5 fluorescent lamps
• Electronic programmed-start ballasts with ballast factors selected for defined illumination
• Dual-technology occupancy sensors and vacancy sensor lighting controls

These projects, completed in 2012, represent approximately $4 million construction, and will save approximately $175,000 each year.
