Norwalk City Hall is undergoing an energy efficient heating, lighting, and automation upgrade that will soon pay back. Lighting sensors are being added to offices, common areas and storage rooms, yielding over 401,000 kilowatt hours of savings.   

The upgrade began just this week, with the Lighting Retrofit Project, which will replace over 2,000 existing T8 fluorescent fixtures with new high efficient T8 bulbs with ballasts and LED's. Approved by CL&P to receive $160,772 of incentive funds,  the project will reduce electric consumption from lighting fixtures by approximately 50 percent, saving the city around $50,000 annually on electricity costs. The city will now pay an out-of-pocket cost of $20,408 with a payback period less than two and a half years for the lighting project's overall cost. 

"The good news to the taxpayers is that we save tremendous amounts of money over the years," said Norwalk Mayor Harry Rilling. "The initial expenditure that we're making now is going to pay dividends down the road and it's going to be a quick turnaround time in recouping our money, but then for the years coming we're going to be saving money that we don't have to spend and the city of Norwalk will be the beneficiary. The taxpayers of the city."

The Boiler Replacement Project has already swapped out two 27-year-old boilers in the City Hall basement with three new 96 percent efficient condensing boilers, sized to support peak winter needs and provide protection against equipment failure.  

"Typically now if you go out to get boilers, it's probably like 85 percent efficient and typically those boilers don't really get incentive money," said Building and Facilities Manager Alan Lo.  

Yankee Gas is expected to provide a grant of $60,000 to the Boiler replacement project's total cost of $280,000. The city is projected to save an excess of $30,000 a year. 

"It saves costs above and beyond energy," said Ron Araujo, director of Conservation & Load Management at CL&P. "The technology that is being installed here today reduces the amount of times it has to be maintained, the lighting doesn't have to be changed out as frequently. That translates into savings and maintenance dollars above and beyond what's being done in the energy front."
