About the Client

The City of Newark is the third largest city in Delaware and has a goal to be a more sustainable city and increase renewable generation in its distributed electricity mix to 100% as soon as practicable. They want a community that is socially fair, economically strong, and an environmentally healthy place to live, work, and play.

The City Manager’s office worked with Seiberlich Trane Energy Services to modernize their facilities infrastructure, upgrade outdoor lighting, and create renewable energy through solar arrays throughout the city. They were able to do this at no cost to the taxpayers by leveraging the energy savings from upgrades that will pay for the entire project over 20 years.

Seiberlich Trane Energy Services went beyond just saving energy and improving equipment operations installing a citywide street & pedestrian lighting control system as well as parking lot lighting controls to promote safety. Additionally, UVGI air purification systems were installed in city air handlers to improve indoor air quality.
