Grass Valley City Hall roof construction completed

As part of Grass Valley's $4 million capital improvements program, the Grass Valley city hall building has just undergone construction for a new roof membrane that city staff say will save the city in energy consumption and funds.

"They put on a new membrane roof, underneath that membrane will be more retro-reflective for heat savings," Public Works Director Tim Kiser said. "But they also put foam underneath it of at least two inches, in some areas it's up to six inches, so it will provide us thermal insulation."

Located at 125 East Main St., the city hall building, along with all city-owned facilities, will get retrofitted with new LED lights as part of the city's capital improvement's program which the city council unanimously approved in November.

All construction for the project will be conducted through OpTerra Energy Services, formerly known as Chevron Energy Solutions, and will include a total of 787 kilowatts of solar power at two locations, a solar water heater for the Memorial Park pool, as well as energy-efficient lighting and HVAC upgrades at numerous city buildings.

The project is estimated to cost more than $3,470,00, financed over 20 years at an interest rate of 4.4 percent. The city, though, expects annual energy savings of roughly $33,000 for the life of the loan, and as much as $400,000 annually following completion of all repairs.

Kiser says construction on the entire project is scheduled to be completed this fall.

"We'll have two remote sites that should promote enough solar to match our usage for everything, sewer, water and general fund facilities," Kiser said. "There's about seven or eight phases all together. Traffic signals will be switched over to the LED lights for every signal the city owns. Other major phases that will occur is all the city lights in the city will be retrofitted to LED as well."
