‘Green stone’ B’klyn

This is one building renovation that even the stroller set in Park Slope can’t gripe about.

A local alternative-energy company is creating the city’s first solar-powered brownstone in the tree-lined Brooklyn neighborhood.

Voltaic Solaire is gut-renovating a century-old brownstone as part of a $1 million project that will create six rental units, a lounge and a restaurant — all powered by the sun.

The site at 367 Fifth Ave., near Fifth Street, will be fully powered by a 15,000-watt solar- panel system on its rooftop and terrace awnings, providing all electric, heat and hot water on site.

“It’s a one-of-a-kind project,” said Ron Faia, a co-owner of Voltaic Solaire.

Apartment rents will run from $1,600 to $2,600 monthly, but there will be big savings on energy costs.

Construction began last week, and should be completed in 2013, Faia added. The historic facade will remain intact.

The company later this year is set to open the nation’s first mixed-use, solar- and wind-powered development, which it constructed on Hamilton Avenue in Carroll Gardens.

The sleek, five-story triangular building, called “The Delta” will feature a bed and breakfast business and restaurant. The building is partly skinned with 1,700 square feet of amber- and red-colored solar panels, matching its brick façade.
