Noribachi completed one of the largest LED retrofit projects of an existing building in the US for the 29-year-old Transportation Security Administration (TSA) headquarters.
The TSA project was a three-year, four-phase project focused on its 550,000-sq-foot building and parking garage. Continue reading
The Shops at Grand Avenue’s parking garage in Milwaukee, Wis., got an LED lighting upgrade, replacing 986 metal halide 150W lights with VPL LED parking vaportight fixtures manufactured by Precision-Paragon (P2), consuming 51 watts each.
The LED retrofit reduced the facility’s lighting energy consumption by over 66 percent. Continue reading
The Metropolitan Airports Commission operates seven airports in the Minnesota Twin Cities area of Minneapolis-St. Paul, and has begun a massive energy-efficiency project including LED lighting at the flagship Minneapolis St. Paul International Airport (MSP). Construction was begun this past week on what the agency said is Minnesota’s largest solar generation project — a 3-MW (megawatt) plant located atop two parking structures. Moreover, the project will include retrofit of more than 7700 metal-halide fixtures to solid-state lighting (SSL) products.
For many buildings, switching to more efficient lighting is one of the “low hanging fruit” for improving energy efficiency. Facility managers are increasingly turning to LED lighting technology to meet their energy efficiency goals.
LED bulbs top the lighting charts in energy efficiency and longevity, and frequently represent a payback of three years or less. However, LEDs may not be the best choice for every application. When considering whether to implement LEDs in your facility, you’ll need to take many factors into account. Continue reading

DENVER – Denver International Airport (DIA) is retrofitting more than 5,400 lights located in the airport’s east and west parking garages with energy-efficient LED fixtures.
The majority of the lights are being replaced with 51-watt LEDs. Combined with other lighting systems in the project, DIA expects a net energy savings of about 45 percent, resulting in energy cost savings of about $327,000 per year. Continue reading
When consumers in Milwaukee, Wisconsin, need to go shopping they have the option to visit the Shops of Grand Avenue. This inviting shopping destination is located conveniently in the heart of Milwaukee and is filled with a fun combination of national chain stores and locally based establishments. Shoppers who are anxious to add the latest fashions to their wardrobes, browse for the perfect gift, or simply run errands all in one place flock to the Shops of Grand Avenue nearly every day of the year. Overall it has always been a lovely and enjoyable experience, at least outside of the parking lot areas.
There are numerous other advanced controls methods that can help facility managers squeeze even more savings out of their facilities’ lighting systems. They include the following:
• Light level tuning. Adds to energy savings by reducing lighting output at modest levels, undetectable to the human eye.
“Often design light levels are needlessly high, so reducing lamp output by 5 to 10 percent can bring energy savings benefits without compromising occupant satisfaction,” Renner says. Continue reading
