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.
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
