Interior Lighting and Controls

Ameresco can install state-of-the-art lighting systems to benefit building occupants and facilities. Our projects replace or upgrades existing fixtures, and will enhance the quality, consistency, and color rendering of your lighting system. Lighting systems offer a broad spectrum of energy optimizing solutions. Sample lighting retrofit scope items include low-wattage, extended life super T8 lamps; scotopic lighting (using LED or fluorescent sources); indoor LED ‘tube’ replacements; indoor LED fixture retrofits and replacements; LED or electroluminescent exit signage; and natural lighting solutions (e.g. skylights, light tubes).

Ameresco deploys lighting controls as well, including occupancy or vacancy sensors; high-end trim; demand-controlled dimming; day lighting; addressable lighting; and advanced window shades. Ameresco has often installed limited scale lighting mockups to solicit facility user feedback regarding proposed changes in advance of a larger-scale project. User feedback has been responsible for modifications to proposed lighting scope, heading off potential user complaints.

Implementation of lighting upgrades saves energy, and results in annual maintenance savings, since installation of new equipment will extend service intervals. Ameresco is fully capable and responsible for meeting your lighting needs.
