The Northeast Sustainable Energy Association (NESEA) is the nation's leading regional education and advocacy association that aims to accelerate the deployment and use of renewable energy, energy efficiency, and green buildings to improve the economy and our quality of life.

Classic oversees media campaigns for two of NESEA's biggest annual events, its Green Building Open House, which welcomes the public to visit "green" homes and learn about clean renewable energy systems in 10 northeast states, and Building Energy, an annual conference and trade show held at the World Trade Center in Boston.  Classic also provides public relations for NESEA's annual Junior Solar Sprint Championships.
